Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

were evaluated for four hours time of onset of first diarrhea (min) total number of drywet

feces and total weight of wet feces (g) (65 66)

38 Phytochemical Evaluation

The initial screening of extracts were performed for different chemical constituents for

example alkaloids steroids terpenoids glycosides tannins phenols saponins and flavonoids

using previously published methods (67-70)

381 Test for Alkaloids

Mayerrsquos reagent and Wagnerrsquos reagent were extensively used to assess the presence of

alkaloids Crude extracts of EEJR NHJR EETG and NHTG were slightly warmed with dilute

HCl for 2 min in separate test tubes Filter paper was used for filtration After that solution was

divided into two parts and poured into two different tubes 2 to 3 drops of Mayerrsquos reagent or

Wagnerrsquos reagent was added in test tube White creamy precipitation was obtained which

showed positive result with Mayerrsquos reagent While reddish-brown precipitate with Wagnerrsquos

reagent confirmed the presence of alkaloids in the extract (71)

3811 Mayerrsquos reagent

5 grams of KI was mixed with DW Then more distilled water (qs) was added to make up its

volume up to 20 ml (Solution A) 136 g of mercuric iodide was mixed in 60 ml DW (Solution

B) After mixing both solutions their final volume was adjusted up to 01 litre (71)

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

26 Plants used

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

26 Plants used

There are eight genera of plant Juglandaccac family while the best-known species of the family

is J regia because it produces timber that can used for many purposes and edible nuts It is

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

34 Assessment of anti-arthritic activities

341 Arthritis induction

Thirty rats were segregated into five groups with each having 6 animals Group-I (vehicle

control) and group-II (arthritic control) were given vehicle ie 1 Tween 80 in water (54)

Group-III was considered as reference group and received piroxicam (10 mgkg bw po)

(58) Group-IV (EEJR) and group-V (NHJR) were treated with the dose of 500 mgkg bw

po respectively While group-VI (EETG) and group-VII (NHTG) were administered 400

mgkg bw po respectively (56) FCA (015 ml) was injected into left paws of all the animals

(sub plantar region) except vehicle control group at 0 day Animals were treated with extracts

and piroxicam starting from day 8 till day 28 (12)

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

26 Plants used

There are eight genera of plant Juglandaccac family while the best-known species of the family

is J regia because it produces timber that can used for many purposes and edible nuts It is

were evaluated for four hours time of onset of first diarrhea (min) total number of drywet

feces and total weight of wet feces (g) (65 66)

38 Phytochemical Evaluation

The initial screening of extracts were performed for different chemical constituents for

example alkaloids steroids terpenoids glycosides tannins phenols saponins and flavonoids

using previously published methods (67-70)

381 Test for Alkaloids

Mayerrsquos reagent and Wagnerrsquos reagent were extensively used to assess the presence of

alkaloids Crude extracts of EEJR NHJR EETG and NHTG were slightly warmed with dilute

HCl for 2 min in separate test tubes Filter paper was used for filtration After that solution was

divided into two parts and poured into two different tubes 2 to 3 drops of Mayerrsquos reagent or

Wagnerrsquos reagent was added in test tube White creamy precipitation was obtained which

showed positive result with Mayerrsquos reagent While reddish-brown precipitate with Wagnerrsquos

reagent confirmed the presence of alkaloids in the extract (71)

3811 Mayerrsquos reagent

5 grams of KI was mixed with DW Then more distilled water (qs) was added to make up its

volume up to 20 ml (Solution A) 136 g of mercuric iodide was mixed in 60 ml DW (Solution

3812 Wagnerrsquos reagent

Two grams of KI and 127 grams of I2 soln were taken in test tube Then DW (qs) was added

in tube up to 10ml (71)

382 Test for the steroids

Crude extracts of EEJR NHJR EETG and NHTG extracts of plant were mixed with 2 ml of

chloroform Conc H2S04 was mixed alongside wall of test tube After that acetic acid (2ml)

was added The formation of Green color confirmed that steroids are present in the extracts

(68)

383 Keller-Kilani for cardiac glycosides

Crude extracts of EEJR NHJR EETG and NHTG were mixed with glacial CH₃COOH (2ml)

having one drop of FeCl3 solution Then 1 ml of conc Sulphuric acid was poured with the wall

of test tube Ultimately dark brown ring appeared that indicates the existence of cardiac

glycosides (70)

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

26 Plants used

There are eight genera of plant Juglandaccac family while the best-known species of the family

is J regia because it produces timber that can used for many purposes and edible nuts It is

cultivated in all over the world especially in South of Asia West Indies South Eastern Eurpoe

Japan and in Eastern and Southern region of US The height of this plant is 25-35m while the

diameter of its trunk is 2m and grow well in full light of moon It is mostly present in mountain

region of Central Asia for the purpose of making medicaments J regia leaves has been

extensively use in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant and hepatoprotective (20)

anti-atherogenic and osteoblastic (23) aphicidal (21) antihyperlipidemic (24)

antiproliferative (25) antitumour immunoregulatory (26) and anti-mycobacterial (27)

activities Walnut is made up of many chemical compounds such as flavonoids caffeic acid

quercetin and ascorbic acid and due to presence of these compounds it has anti-oxidant activity

13

(50) The roots of Juglans are use to treat diabetes and its related drugs The leaves of plant

have anti-inflammatory anthelmintic depurative and astringent activity Thus they are used

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

were evaluated for four hours time of onset of first diarrhea (min) total number of drywet

feces and total weight of wet feces (g) (65 66)

38 Phytochemical Evaluation

The initial screening of extracts were performed for different chemical constituents for

example alkaloids steroids terpenoids glycosides tannins phenols saponins and flavonoids

using previously published methods (67-70)

381 Test for Alkaloids

Mayerrsquos reagent and Wagnerrsquos reagent were extensively used to assess the presence of

alkaloids Crude extracts of EEJR NHJR EETG and NHTG were slightly warmed with dilute

HCl for 2 min in separate test tubes Filter paper was used for filtration After that solution was

divided into two parts and poured into two different tubes 2 to 3 drops of Mayerrsquos reagent or

Wagnerrsquos reagent was added in test tube White creamy precipitation was obtained which

showed positive result with Mayerrsquos reagent While reddish-brown precipitate with Wagnerrsquos

reagent confirmed the presence of alkaloids in the extract (71)

3811 Mayerrsquos reagent

5 grams of KI was mixed with DW Then more distilled water (qs) was added to make up its

volume up to 20 ml (Solution A) 136 g of mercuric iodide was mixed in 60 ml DW (Solution

B) After mixing both solutions their final volume was adjusted up to 01 litre (71)

31

3812 Wagnerrsquos reagent

Two grams of KI and 127 grams of I2 soln were taken in test tube Then DW (qs) was added

in tube up to 10ml (71)

382 Test for the steroids

Crude extracts of EEJR NHJR EETG and NHTG extracts of plant were mixed with 2 ml of

chloroform Conc H2S04 was mixed alongside wall of test tube After that acetic acid (2ml)

was added The formation of Green color confirmed that steroids are present in the extracts

(68)

383 Keller-Kilani for cardiac glycosides

Crude extracts of EEJR NHJR EETG and NHTG were mixed with glacial CH₃COOH (2ml)

having one drop of FeCl3 solution Then 1 ml of conc Sulphuric acid was poured with the wall

of test tube Ultimately dark brown ring appeared that indicates the existence of cardiac

glycosides (70)

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

26 Plants used

There are eight genera of plant Juglandaccac family while the best-known species of the family

is J regia because it produces timber that can used for many purposes and edible nuts It is

cultivated in all over the world especially in South of Asia West Indies South Eastern Eurpoe

Japan and in Eastern and Southern region of US The height of this plant is 25-35m while the

diameter of its trunk is 2m and grow well in full light of moon It is mostly present in mountain

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population

Evaluation of anti-inflammatory and anti-arthritic activities of

Juglans regia L and Trigonella gharuensis Rechf

ABSTRACT

Background The genus of Juglans and Trigonella have long been used in folk remedy for the

treatment of rheumatoid arthritis and inflammatory disorders The leaves of Juglans regia and

herb of Trigonella gharuensis were collected from Northeast and Southwest areas of Pakistan

respectively

Purpose The study aimed to investigate the immunomodulatory and anti-inflammatory

activities of ethanol and n-hexane extracts of J regia and T gharuensis in different in-vivo

models of acute and chronic inflammation

Methodology Arthritis was induced in rodents using Freundrsquos complete adjuvant induced

model of chronic inflammation Extracts of J regia leaves and T gharuensis were administered

in the doses of 500 mgkg bw po and 400 mgkg bw po respectively Treatment was

started at 8th day of arthritic induction and sustained for 20 days with extracts and piroxicam

as control At 28th day all animals were sacrificed Arthritis was determined using an arthritic

scoring index Blood analysis and biochemical parameters were determined RNA extraction

reverse transcription and polymerase chain reaction (RT-PCR) was performed to determine

expression of pro-inflammatory cytokines such as TNF-α NF-ĸB IL-6 IL-1β COX-1 COX-

2 and anti-inflammatory cytokine IL-4 Prostaglandin E2 level (PGE2) was evaluated using

ELISA Paw edemas were measured using digital water plethysmometer

For evaluation of anti-inflammatory activities acute inflammatory paw edema models

(carrageenan- histamine- serotonin- and dextran-induced paw edema) ear edema model

xx

(xylene-induced ear edema) and castor oil-induced diarrhea model were used Qualitative

analysis and gas chromatography-mass spectrometry (GC-MS) analysis were performed for

the identification of potential anti-inflammatory phytochemicals

Results Treatment with J regia and T gharuensis extracts inhibited arthritic development and

significantly attenuated paw edema All evaluated histopathological parameters were found

significantly reduced after treatment with plant extracts The RT-PCR analysis showed

significant attenuation of pro-inflammatory TNF-α NF-κB IL-6 and IL-1β levels and

potentiation of IL-4 levels COX-2 expression level was also found reduced in extracts treated

groups ELISA demonstrated suppression of PGE2 levels in all extracts treated groups The

results of all extracts were comparable to the effects of piroxicam The treated groups restored

levels of Hb and RBC Moreover levels of WBCs and platelets were found to be nearly

normalized in treated groups The non-significant difference in the levels of creatinine urea

ALT and AST were observed Both plants extracts significantly reduced paw edema induced

by carrageenan in first (early) and second (late) acute inflammation phases indicating the

possible inhibition of autacoids as one of the mechanisms of anti-inflammatory activity The

extracts also significantly prevented histamine- and serotonin-induced paw edema which

complemented inhibition of carrageenan-induced inflammation in the first acute phase

Suppression of edema by plant extracts in dextran- and xylene-induced inflammatory models

supported inhibition of autacoids Attenuation of castor oil-induced diarrhea by both extracts

supported inhibition of carrageenan-induced inflammation via prostaglandin inhibition in the

second acute inflammation phase Qualitative phytochemical screening and gas

chromatography-mass spectrometry analysis indicated constituents with anti-inflammatory

activity for example fatty acid esters and flavonoids in both extracts

xxi

Conclusion Extracts of J regia leaves and T gharuensis herb ameliorated experimentally

induced arthritis which may be ascribed to their immunomodulatory effects Moreover

attenuation of inflammatory edema in different acute models not only validated anti-

inflammatory potential but also suggested possible inhibition of autacoids as one of the

mechanisms along with immunomodulatory effects of both plants

CHAPTER 1 INTRODUCTION

Rheumatoid arthritis (RA) is a chronic and autoimmune disease having worldwide prevalence

of 1 in industrialized populations (1 2) The symptoms of RA are characterized by stiffness

pain synovitis of diarthrodial joints resulting into articular destruction bone erosion and

pannus formation (3) TNF-α (tumor necrosis factor-α) stimulates IL-6 (interleukin-6)

production which causes deterioration of proteoglycans and collagen causing joint destruction

(4) It is also stimulator of B and T cells (5) IL-1β (interleukin-1 beta) is present in inflamed

rheumatoid synovial tissue and stimulates bone erosion and pannus formation NF-κB (Nuclear

factor-κB) stimulates recruitment of pro-inflammatory cytokines such as TNF-α IL-1β and IL-

6 (6) Activation of cyclo-oxygenase-2 (COX-2) by NF-κB exacerbates the inflammation

COX-2 activation also leads to the production of prostaglandin-E2 (PGE2) which in turn

causes bone erosion and cartilage destruction All these cytokines contribute towards

progression of RA (7 8)

FCA was used to induce arthritis in rat model Induction of arthritis through FCA in rat paw is

a well-recognized model of arthritis The features of this chronic poly-arthritic model closely

resemble with human arthritic model This model has been extensively used to evaluate anti-

inflammatory and immunomodulatory properties of plant extracts and therapeutic agents (9)

Inflammation is regarded as cardinal answer to injury and pathogens caused by body It is

manifested by augmented vascular permeability recruitment of leukocytes release of

cytokines and chemotaxis The two types of inflammatory conditions acute and chronic are

based on time duration and underlying cascades of events that lead to physical symptoms The

acute phase can be further classified into first (early) and second (late) phases (10) The early

acute phase is caused by the release of histamine and serotonin followed by the release of

2

bradykinin prostaglandins leukotrienes and activation of polymorphonuclear cells in the late

acute phase Increased vascular permeability leads to edema and inflammation (11 12)

Although inflammation is a shielding phenomenon of the body to injurious stimuli but its

pathophysiological implications are often undesirable Steroids opiates and Non-steroidal

anti-inflammatory drugs (NSAIDs) are preferred remedies to control the negative outcomes of

inflammation (13) Various disease-modifying anti-rheumatic drugs (DMARD) such as

methotrexate TNF-α and IL-1β antagonists have been used to treat autoimmune disorders but

their use is limited due to higher vulnerability of patients to infections (14 15) NSAIDs may

induce gastric perforation erosion and bleeding due to inhibition of prostaglandins (16)

Tolerance and dependence are associated with opiates (3) Peptic ulcer precipitation of

diabetes osteoporosis and increased susceptibility to infections are associated with

corticosteroids (17)

DMARDs are used as the mainstream for the management of inflammation and pain in arthritic

patients in addition to NSAIDs However the adverse effects of synthetic drugs suggest a need

to focus on medicinal plants due to the easy availability of plants and lower cost (18) The

undesirable adverse effects of above mentioned drugs specify worth of traditional medicinal

plants for the cure of inflammation and arthritis (19)

Juglans regia L (Enaglish name walnut local name Akhrot) belongs to the family

Juglandaceae These plants are distributed all over the world in temperate regions in particular

Asia United States Western South America and Europe (20) J regia leaves have been

extensively used in the pharmaceutical and cosmetic industry due to its easy accessibility (21)

Traditionally J regia leaves have been used to treat rheumatic pains (22) Its decoction has

also been used for rheumatic pain and inflammatory disorders (7) The plant is known to

possess antinociceptive (21) antidiabetic antimicrobial antioxidant hepatoprotective (20)

3

anti-atherogenic osteoblastic (23) aphicidal (21) antihyperlipidemic (24) antiproliferative

(25) antitumour immunoregulatory (26) and antimycobacterial (27) activities

Trigonella gharuensis Rech f is collected from the hilly areas of Quetta It is perennial herb

suberect 6-9 mm broad 50cm tall 14 cm long Petiole 1 cm long leaflets (28) Its distribution

is worldwide (29) It belongs to family Fabeacae the second largest family of flowering plants

(30) Traditionally member of genus Trigonella were used to treat inflammatory diseases

Different plants of Trigonella genus such as Trigonella stellate and Trigonella foenum

graceum possess known pharmacological anti-inflammatory properties (18 31) T gharuensis

is also known for possessing medicinally important active ingredients (32) We did not find out

any literature regarding its anti-inflammatory prospective So prime focus of this study was to

explore its anti-arthritic and anti-inflammatory potential

In order to evaluate antirheumatic properties of J regia and T gharuensis using FCA induced

chronic model of inflammation this current study was performed Furthermore this study also

investigated anti-inflammatory mechanisms of both plant extracts in various acute

inflammatory models using mice

11 Hypothesis

111 Null hypothesis

Extracts of J regia and T gharuensis do not possess anti-arthritic and anti-inflammatory

properties

112 Alternate hypothesis

Extracts of J regia and T gharuensis possess anti-arthritic and anti-inflammatory properties

CHAPTER 2 LITERATURE REVIEW

Rheumatoid arthritis (RA) is progressive as well as reversible when diagnosed at early stages

Joint inflammation redness cartilage damage and bone erosion are prominent clinical

manifestations of RA Laboratory findings showed leukocytosis anemia fever weight loss

and anorexia Joint inflammation is absent in early rheumatoid arthritis However when disease

progresses joint swelling appears with fusiform appearance RA can be classified into four

stages First stage does not include any destructive changes Second stage includes moderate

destruction of subchondral bone and cartilage damage Joint deformities are absent at this stage

although mobility of joint is compromised Stage 3 is crucial and it causes muscle atrophy

Stage 4 involves lesion of soft tissues of extra-articular organs (33) Extra articular involvement

affects other organs such as eyes lungs renal nervous system and various gastrointestinal

system It usually associated with mortality Usually 40 patients get affected with extra

articular disease when they encountered with this disease and during the course of disease (34)

21 Epidemiology

Rheumatoid arthritis is occurring throughout world Majority of population suffering with this

disease and its estimated prevalence is about 05-1 in Northern Europe and North American

and mean annual incidence is 002ndash005 Patient survival is decreased in 3 to 10 years It is a

multifactorial disease involving genetic as well as environmental factors The major risk factors

are sex age smoking infectious agents These factors contribute towards severity of disease

Females have higher risk of developing arthritis as compared to male due to estrogen which

has stimulatory effect on immune system (35)

Cytokines control inflammatory processes which participate in RA progression Imbalance is

well understood between anti-inflammatory and pro-inflammatory roles of cytokines This

5

imbalance causes the stimulation of chronic inflammatory mediators as a result of which ankle

joint damage occurs Therefore cytokines are the new targets for the treatment of arthritis (36)

22 Pathophysiology

Immunologic mechanisms RA gave a wide knowledge about the pathogenesis and etiology of

rheumatoid arthritis However the exact immune pathways for understanding pathogenesis and

etiology of RA is still insufficient There are some clinical and pathological manifestations that

are obtained from the activation of various interrelated immune pathways Modern concepts of

RA that is supported by laboratory studies animal models and clinical observation have

revised and reestablished some of the opinions Early study emphasized on the importance of

immune complexes and auto-antibodies in the initiation of RA It suggested a function of T

cells in initiating inflammatory response in RA It was recognized that these interrelated

mechanisms suggestively contribute in pathogenesis of RA T cells also play function in

initiating and perpetuation of disease Immune pathways play role in defining the implication

of possible treatment because their modulation directed towards specific targets gives benefits

to the patients suffering with RA (36)

RA is a progressive autoimmune disease having systemic effects The precise pathogenesis of

this disease is unidentified but there are some environmental as well as genetic factors which

play contributory role in this disease The interaction between pro-inflammatory cytokines as

well as B- and T cells promotes progression of RA The destruction of joint starts from synovial

membrane Activation of mononuclear cells and angiogenesis leads to synovitis in joints

Pannus is a part of the synovial membrane that is rich with osteoclast cells Pannus destroys

bones and the enzymes which are released by chondrocytes and synoviocytes degrade the

cartilage Antigen-activated CD4 T cells strengthen the immune response of body by activating

osteoclast mononuclear cells chondrocytes and also synovial fibroblasts The release of

6

cytokines from these cells especially the release of TNF-α IL-1 and IL-6 lead to inflammation

of synovial membrane In addition to articular effects of cytokines the pro-inflammatory

cytokines stimulate the systemic effects which include acute-phase proteins production

cardiovascular diseases anemia and osteoporosis (37)

Synovial fibroblast is a part of composite cellular network that plays a significant function in

pathogenesis of RA Lymphocytes and macrophages secreted factors that play role in the

activation of fibroblasts This activation pattern is further characterized by the changes in

regulating signaling cascades and genes expression and alterations in these pathways lead to

apoptosis (38) IL-1 along with TNF-α play role in dys-regulation of cartilage and bone

remodeling characteristics of RA In case of bone remodeling both cytokines stimulate the

formation of NF-κB ligand receptor activator that plays role in stimulating bone resorption

caused by osteoclastic activity TNF-α increases the formation of mature osteoclasts IL-1

cytokines show its effect directly on osteoclast to stimulate both cells which stimulate bone-

resorbing ability TNFα and IL-1 both cytokines aggravate the remodeling of cartilage but IL-

1 cytokine is more effective than another This cytokine stimulates the production of factors

and also increase degradation of cartilage matrix The improved understanding of pathways

mechanism that underlays the processes of destruction of the joint will enable for more specific

and selective application of pharmacological and therapeutic agents which target these pro-

inflammatory cytokines (39)

Study was conducted to determine different types of arthritis that was expressed by both

biologically and histo-chemically active nerve growth factor in synovium A model of arthritis

induced by carrageenan was used to assess joint inflammation on the level of NGF The study

determined that in the rats experimentally induced arthritis is caused by stimulation in nerve

growth factor in peri-vascular area in synovium It was determined that nerve growth factor

7

injection in synovium did not lead to any inflammation and destruction of the peripheral

sympathetic innervations considerably reduced both level of nerve growth factor and

inflammation following carrageenan injection

A histomorphometric method was used to determine the association between ostopenia and

arthritis that emphasized total changes in the composition of bone Carrageenan injection was

injected into the knee of mature rabbit to check the trabecular bone volume and its turnover

Histomorphometry method was used to study trabecular bone volume of femoral condyles and

was established by the special technique photodensitometry on the standard macroradiographs

Calcein fluorochrome is a newly developed technique that was used to study osteogenesis by

using histological sections which were not decalcified A major defeat of the cancellous bone

occurred within 49 days in lateral and medial femoral condyle in the arthritis group The net

Osteogenesis was emphasized within four hold It was considered that rise in the total bone

resorption leads to negative bone balance The study also showed that periarticular bone loss

of the RA is also directly linked with increased bone turnover When quantitative study on the

kinetics of bone remodeling in RA was done it provides the foundation for therapeutic attempts

to reverse or prevent the therapeutic attempts Osteopenia also increases the risk of fracture in

inflammatory arthritis (40)

23 Treatments

NSAIDs are extensively used drugs all over the world The adverse effects which restrain its

uses is GIT bleeding Endoscopic studies showed that 15 to 30 of patients usually

encountered with gastric or duodenal ulcer The major side effects of NSAIDs are bleeding and

more than 100000 patients are hospitalized and among which 16500 patients die as a result of

gastrointestinal events in the United States NSAIDS inhibited cyclooxygenase which is

involved in the synthesis of prostaglandin COX-I is overexpressed constitutively and it

8

protects gastric mucosa While COX-2 increases prostaglandin production which mediates

inflammation COX-2 inhibition prevented harmful effects of prostaglandin which is

inflammation and pain while COX-I inhibition is associated with harmful effects in the GIT

wall and inhibition of platelets aggregation Agents that inhibit COX-2 enymes showed similar

effects such as reduction of inflammation and pain similar to non-selective NSAIDs (41)

NSAIDs was invented in 1972 and they was introduced in market in 1982 by Pfizer Piroxicam

has long half-life which is 45 hours in human being It possesses analgesic and antipyretic It

has been used in treatment of RA Like others NSAIDs its mechanism of action is inhibition of

cyclooxygenase (42)

Cyclooxygenase act on arachidonic acid to form prostaglandins While isomers of these

enzymes transform the arachidonic acid to prostaglandins COX-1 a constitutive enzyme form

is present in the human body and play a role in the homeostatic function for example influence

blood flow and maintain normal gastric mucosa The COX-2 on another hand acts as an

inducer and is expressed to physiological stimuli and is also concerned in prostaglandins

production which arbitrate the pain as well as inflammation Non-specifically the Nonsteroidal

anti-inflammatory drugs (NSAIDs) reduce the production of both forms The beneficial effects

of NSAIDs through minimizing inflammation and producing analgesic effects occur by

decreasing synthesis of COX-2 but with some unwanted effects like mild bleeding and

gastrointestinal adverse effects occur due to concurrent inhibition of important COX-1 The

agents which selectively decrease the COX-2 synthesis while sparing the COX-1 regarded as

an highly interesting and beneficial therapeutically and can also characterize as a chief progress

in the treatment of RA as well as osteoarthritis (43)

Inhibitors of synthesis of PGE2 nonsteroidal anti-inflammatory drugs and some other

prostanoids can be used in the treatment the RA To understand mechanism by which

prostaglandin plays role in pathogenesis of this disease experiment was conducted on rats

9

Rats which lack each of the four known prostaglandin receptor E2 receptors were used

Homozygous deletion of all receptors (E1 E2 and E3) did not influence the arthritis

development while disease progress was found in mice which have low expression of above-

mentioned receptor These rats also showed the reduction in the inflammation when assessed

with low circulating serum amyloid A and IL-6 levels Therefore antagonists of these receptors

give new agents for treatment of RA (44)

Cyclooxygenase-2 is stimulated in inflamed joint tissues and is involved in the production of

prostaglandin While the exact phenomenon of cyclooxygenase expression is regulated stays

to be elucidated Various study suggested that prostaglandin play role in inflammation

angiogenesis and apoptosis These events are responsible of possible structural changes which

characterize the arthritic disease NSAIDs are prescribed for the treatment of RA and give

effective relief from the symptoms of RA while serious GIT complications occur with their

use The mechanism by which NSAIDS can reduce pain and inflammation in patients of

rheumatoid arthritis is that they inhibit the production of cyclooxygenase -2 while toxicity is

related to inhibition of COX-1 Selective C0X-2 inhibitors show better results when compared

with placebo and are effective for the management of RA symptoms They also improve the

GIT safety and tolerability Various studies also shows that there is still some complication of

NSAIDs with the selective COX-2 inhibitors The major feature is the rheumatoid arthritis is

overexpression of -2 protein in articular tissues While the exact molecular mechanisms are

still unclear By understanding more clear mechanism of COX-2 it will become effective to

treat rheumatoid arthritis easily

When anti-tumur necrosis factor α antibody (infliximab) and methotrexate are administered in

a combination for the treatment of RA it shows a positive effect Though some patients did

not show any response to this treatment The study was conducted on a patients with

10

rheumatoid arthritis by administering repeated high dose of intra-articular infliximab and

infliximab infusions into an inflamed knee When the patient was assessed it was determined

that that there were not any clinical effects When knee arthroscopic biopsy was done before

injection it was demonstrated that TNFα staining was present there Moreover

immunohistochemistry report revealed presence of lymphotoxin α Thus it was suggested that

the resistance to TNF receptor blockage might be due to insufficient amount of TNFα The

study also suggested that LTα may also have a significant role in RA

RA synovium is associated with increased levels of COX-2 as well as angiogenesis Both

phenomena were investigated and it was found that selective COX-2 inhibitor such as rofecoxib

effects on human dermal and reduce ability of angiogenesis and chemotactic activity The

pretreatment with selective COX-2 inhibitor (rofecoxib) considerably decreased angiogenesis

When RA was firstly treated with selective COX-2 inhibitor (rofecoxib) for at least 14 hours

followed by stimulation with the IL-1β less angiogenesis was observed The COX-2 induced

angiogenic activity is the important active mechanism in RA synovium hence these are

preferred drug therapies in the treatment of RA

24 Inflammation

Inflammation helps the body in healing wounds infections or damage and without

inflammatory response it is impossible to heal wounds Inflammation is very beneficial for the

body but can also be harmful if it is present in more quantity and can persist in body for long

time than usual When a baby is born various defences are naturally present in the body of

human which is known as innate immunity Inflammation is of two types In acute

inflammation onset of action in acute inflammation is very rapid however time period of

action is short The symptoms of chronic and acute inflammation vary depending upon nature

of disease The causes of acute inflammation are chemical agents (tissue necrosis reducing

11

agents alkalis and corrosive acids) physical agents (trauma vibration heat cold ionizing

agents) hypersensitivity reactions and microbial infections Chronic inflammation has slow

onset of action but duration of action is long

25 Role of Carrageenan histamine serotonin xylene and dextran

Carrageenan is commonly used chemical that play role in releasing inflammatory and

histamine prostaglandins leukotrienes TNF-α as well as bradykinin Acute inflammation

route of carrageenan is a biphasic and when carageenan is injected serotonin kinins and

histamine is released in first phase while second phase is responsible of release of prostaglandin

(45)

Histamine play crucial part in early inflammatory response Stored histamine present in white

blood cells eg basophils eosinophils and mast cells Mast cells are present in large quantity

at the site of potential injury such as feet mouth internal body surfaces nose and blood vessels

Non-mast cells histamine is also found in various tissues such as in brain where it functions as

neurotransmitter Another significant site where histamine is stored and released is ECL of

stomach The important function of histamine release from mast cells and basophils is

immunologic (46)

Basophilocytes from the patients (patients with rheumatoid arthritis) respond to the leukocyte

nuclei from normal people with the release of histamine A similar release of histamine induced

by nuclear components of DNA and RNA has been demonstrated in normal people Patients

with RA were treated with anti-histamines (H1 and H2) and results showed that there was a

direct effect of histamine in RA (47)

12

Serotonin has two functions related to inflammation that it increases vascular permeability and

causes vasodilation It is also a vasoactive amine just like histamine It also plays role in the

dilation of capillaries and in contraction of non-vascular smooth muscles (48)

Xylene is responsible for severe vasodilation and can cause edematous changes of skin that is

sign of acute inflammation Xylene is also responsible for histopathological changes such as it

increase the thickness of skin tissues when it is applied topically (49)

Dextran is responsible for infilteration of mononuclear cells as well as regenerative changes in

epithelium The exact mechanism through which dextran play role in inflammation is no clear

but studies show that it induces B cells T cells macrophages and polymorphonuclear changes

CHAPTER 5 DISCUSSION

The roles of anti-inflammatory and immunomodulatory substances in treating chronic

inflammatory conditions are well established RA is characterized by over production of TNF-

α NF-ĸB IL-6 IL-1β and PGE2 and reduced levels of anti-inflammatory IL-4 Substances

which down regulate pro-inflammatory cytokines have gained importance in the treatment of

inflammatory disorders (58 60)

J regia and T gharuensis have been frequently used for the treatment of arthritis in folk

medicine (56) FCA-induced model of rheumatoid arthritis is preferred due to its similarities

with human arthritic disorder characterized by synovial hyperplasia vascular formation

cartilage destruction and bone erosion (12) The pannus formation is a hallmark of RA which

is mainly composed of macrophages and fibroblasts like synoviocytes (73) It is believed that

erosion observed during rheumatic diseases is mainly due to TNF-α IL-6 and IL-1β (74) J

regia and T gharuensis extracts significantly attenuated bone erosion and pannus formation in

joints which was ascribed to attenuation of pro-inflammatory cytokines levels

The key focus in the treatment of RA is to reduce inflammation caused by pro-inflammatory

cytokines TNF-α is considered as main cytokine involved in the inflammatory disorders It

activates IL-6 in both paracrine and autocrine manner Activation of fibroblasts by TNF-α tends

to destroy cartilage by producing matrix degrading enzyme (58) NF-ĸB is associated with

resorption of bone by differentiation besides activation of osteoclasts These events also lead

to the development of Th1 response It is a transcription factor which activates other cytokines

IL-6 TNF-α in addition IL-1β and causes recruitment neutrophils as well as activation COX-

2 is activated by NF-ĸB thus amplifying prostaglandin production and inflammatory response

(5) This study showed that J regia and T gharuensis significantly decreased TNF-α and NF-

169

ĸB mRNA expression levels This might had caused minimizing of bone erosion inflammation

and formation of pannus These consequences are in line with the previous study (2)

IL-6 was considered a major instigator of joint inflammation in RA Earlier studies showed

that IL-1β and TNF-α are the major inducers of IL-6 and these are further responsible for

synovial inflammation and cartilage destruction in arthritic patients (75) It was a pleiotropic

cytokine maintaining hematopoiesis and bone metabolism It also regulated many immune

responses Increased production of IL-6 results into systemic inflammation and auto-immune

disorders It is responsible for osteoporosis and joint destruction in RA patients Inhibition of

IL-6 can prevent osteoclast activity in RA patients (76) IL-1β is more abundant in the

destructive tissues of RA patients (77) It is over expressed in inflamed synovial tissue

particularly in synovial lining and is elevated in lymphatic drainage of affected joints In

addition it is localized in affected joint thus causing pannus formation in the arthritic patients

(78) An increase in IL-1β levels in joints has been associated with the histological features of

RA There is a reason to believe that IL-1β is an essential cytokine that promotes inflammation

and joint destruction in RA (6) J regia and T gharuensis attenuated the mRNA levels Our

outcomes of this research study are similar with the inferences of already published study

which established that attenuated levels of IL-1β and IL-6 reduced cartilage and bone

destruction (79)

IL-4 mediates anti-inflammatory response and repression of macrophage activation (80)

Moreover it is responsible for negative regulation of NF-ĸB by increasing IКB IL-4 inhibits

osteoclasts which is liable for destruction of cartilage and bone erosion occur in arthritic

patients (81) Therapy with recombinant IL-4 have resulted in the inhibition of cytokine

production in patients suffering from RA (82) J regia and T gharuensis extracts significantly

170

increased IL-4 levels thus reducing RA development by upregulating anti-inflammatory

response

COX-1 and COX-2 enzymes possess effective physiological roles in biological signaling

pathways COX-1 entails homeostatic and inflammation-modulating potentials while COX-2

induces generation of prostaglandins to carry out inflammatory and pain outcomes (83) COX-

2 is over expressed in RA resulting in the over-production of PGE2 (84 85) Various studies

describe functions of COX-1 in maintaining the gastric mucosa integrity facilitating normal

platelet function and regulating renal blood flow The COX-1 and COX-2 levels were

significantly reduced by J regia and T gharuensis which could result in the inhibition of PGE2

levels However the extent of COX-1 suppression did not significantly counter the constitutive

outcomes of COX-1 which is in line with the results of other studies that the constitutive

functions of this enzyme are hardly affected in COX-1 knock-out mice (83)

We evaluated the levels of PGE2 and found high levels in arthritic control group (86) Binding

of PGE2 to prostaglandin receptors initiate the process of erosion of juxta-articular cartilage

(58) Treatment with J regia and T gharuensis attenuated PGE2 levels These outcomes are

in line with the study of (60 73) who showed that suppression of PGE2 was involved in bone

remodeling and suppression of inflammation caused by arthritis The considerable reduction of

TNF-α IL-6 IL-1β and increased levels of IL-4 in extracts treated groups confirm

immunomodulatory role of both extracts (87)

Hb content and RBC counts were reduced in arthritic control group which indicate anemic

condition in rats The anemia might be associated to low plasma iron levels that is negatively

correlated with significantly higher IL-6 levels (88 89) Bone marrow produced inadequate

cells in anemia and aberrant deposits of iron in synovial tissues (12) J regia and T gharuensis

171

nearly normalized these altered hematological parameters which are in accordance with the

result of the previous study (10) On the other hand WBC and platelet counts were found

increased in blood samples IL-6 could be responsible for high rise in leukocyte levels and

platelets (90 91) Treatment with J regia and T gharuensis restored white blood cell counts

and platelets Increased levels of ALP may be responsible for bone destruction and

mineralization (58) Both plant extracts and piroxicam significantly reduced ALP levels in

treatment groups To find out the safety of extracts we measured different biochemical

parameters for instance urea creatinine ALT and AST levels The results explained that no

significant difference was observed among all groups Hence validating the safety of extracts

in term of liver and renal parameters

Inflammation is a normal body response to harmful agents in order to get rid of noxious stimuli

but uncontrolled inflammation may lead to tissue damage (92) Modern scientific research is

inclined towards treatment of inflammation with natural products having least side effects and

being cheapest source (18) Investigation of anti-inflammatory activities of J regia and T

gharuensis extracts were performed using carrageenan as phlogistic agents while various other

agents were used to determine the autacoids inhibition as one the anti-inflammatory

mechanisms by extracts of plants Different supporting models like dextran-induced paw

edema castor oil-induced diarrhea and xylene-induced ear edema were also developed to

strengthen the inferences (93)

An excellent model was used for elucidation of the cascade of complex events such as

carrageenan-induced edema especially the interactions of autacoids as an anti-inflammatory

mechanism The first phase (1-2 h) started with the release of histamine serotonin and kinin

while the second phase was ascribed with the release of prostaglandin and bradykinins (12)

Extracts of J regia and T gharuensis inhibited paw edema at first stage and prevention was

172

also observed till fifth hours indicating its efficacy at second stage Results were authenticated

with the inferences of reported literature (56 94)

To determine possible inhibitory effect on markers involved in first phase we further

developed serotonin- as well as histamine- induced paw edema models Histamine and

serotonin increase vascular permeability and are potent vasodilators which in turn accumulate

fluids and leukocytes imparting edema and inflammation (95) All these events contribute

towards principal signs of inflammation It was previously suggested that inhibitory effect of

plant extracts determined using both serotonin- and histamine- induced paw edema models

might be ascribed to the inhibition of releasesynthesis of these autacoids (12) Significant

inhibitions were observed in both models when they were pre-treated with extracts of plants

Similar to the results of carrageenan-induced paw edema pre-treatment with ethanolic and n-

hexane extracts caused significantly higher prevention of paw edema These results were

further validated through dextran-induced paw edema model

Dextran-induced paw edema was commonly taken as an experimental model for inflammation

This model was accompanied by different mechanism of inflammation such as vascular

permeation which was increased due to release of serotonin and histamine followed by

activated kinins further promoted accumulation of neutrophils and osmotic edema having low

protein levels (96) The ethanolic as well as n-hexane extracts of J regia and T gharuensis

prevented dextran-induced paw edema significantly thus strengthening the inhibitory effects

of J regia and T gharuensis found using two different paw edema models induced by

histamine and serotonin

Xylene-induced ear edema was another model used to further strengthen inhibitory effects of

J regia and T gharuensis extracts on autacoids inhibitions Xylene mediates the release of

substance P an undecapeptide neurotransmitter which is widely distributed in central as well

173

as peripheral nervous system responsible for many physiological processes Vasodilation and

plasma extravasation caused by the release of substance P result into neurogenic inflammation

(97) Other studies described that mechanism of xylene induced inflammation was also in part

involved with the release of histamine and other mediators (98) The two suggested

mechanisms of inflammation are interlinked as substance P and histamine both induce the

release of each other Thus inhibition of substance P can negatively influence the release of

histamine and vice versa (99) Current study revealed that inhibition of paw edema induced by

histamine further validates attenuation of xylene-induced ear edema Thus inhibition of ear

edema further validated autacoids inhibition was another unique anti-inflammatory mechanism

of J regia and T gharuensis extracts

Castor-oil induced diarrhea model was used to evaluate role of prostaglandins in inflammatory

conditions (100) Castor oil is metabolized to ricinoleic acid which irritates the gastric mucosa

The irritation of mucosa in turn releases prostaglandin which stimulates intestinal motility and

mucus secretion (101) Both ethanolic and n-hexane extracts of J regia and T gharuensis

significantly prevented diarrhea Inhibition of castor oil-induced diarrhea validated inhibitory

effect of plants extracts in 2nd stage of carrageenan-induced paw edema Thus plants extracts

inhibited prostaglandin which was also suggested along with inhibition of histamine and

serotonin as underlying mechanisms of anti-inflammatory activity Plant extracts having

important biological compounds such as tannin flavonoids and alkaloids had been described

to have considerable anti-diarrheal activity (102 103) Flavonoids especially played an

imperative part in inhibiting synthesis of prostaglandin (104 105) Qualitative analysis of

plants extracts revealed that these contained flavonoids alkaloids and tannins in both plant

extracts which might be attributed anti-diarrheal activity and prostaglandin inhibitory activity

Anti-inflammatory activities are also frequently reported with detected phytochemical

constituents in current study (106)

174

Experimental studies of acute toxicity of plants extracts revealed that extracts were found

nontoxic at 2 gkg for J rgia and 16 gkg for T gharuensis The extract did not show any sign

of mortality and behavior changes This is in line with findings of Ruijun et al (53)

The GC-MS method is considered a direct and precise technique to evaluate the presence of

medicinally important components in plant extracts The analysis showed that J regia and T

gharuensis possesses different constituents with previously reported anti-inflammatory and

anti-oxidant properties such as methyl linoleate phytol along with squalene (107 108)

Presence of phytol ethyl palmitate and nonacosane impart anti-inflammatory activity to EETG

and to n-hexane NHTG extract Costunolide (224-trimethy-1233a68a-hexahydroazulene-

57-dicarbaldehyde) present in n-hexane extract of J regia significantly reduced

inflammation by inhibiting NF-kB (Chaturvedi et al 2011) and inhibits IL-1β expression

levels (109) hence validating the anti-inflammatory properties of J regia and T gharuensis

extracts The 388-Trimethoxy-3-piperidyl-22-binaphthalene-1144-tetrone present in n-

hexane extract of J regia also attenuated inflammation because it possessed considerable anti-

inflammatory and anti-arthritic properties (110) Ezhilan and Neelamegam had stated that 12-

Benzenedicarboxylic acid mono (2-ethylhexyl) ester retained considerable anti-inflammatory

in addition to antioxidant properties and interestingly we have found this compound in our

extract (111)

175

CHAPTER 6 CONCLUSION

The current study validates the traditional use of J regia and T gharuensis in inflammatory

disorders and RA Amelioration of joint inflammation in both acute and chronic models of

inflammation highlighted that J regia and T gharuensis extracts possessed significant

immunomodulatory and anti-inflammatory properties The attenuation of RA might be

ascribed to downregulation of pro-inflammatory markers such as TNF-α IL- -6 NF-kB COX-

1 and COX-2 and up-regulation of anti-inflammatory IL-4 Moreover PGE2 levels were also

found reduced after treatment with plant extracts The inhibition of autacoids in different

models of acute inflammation is suggested as one of the possible mechanisms of anti-

inflammatory activity Further studies are warranted to isolate active phytochemicals which

are responsible for anti-arthritic and anti-inflammatory effects

176

FUTURE PERSPECTIVE

J regia and T gharuensis possess considerable anti-arthritic compounds and anti-

inflammatory compounds which should be separated on the basis of activity-based

fractionation and isolation of compounds

Plants extracts should be administered through specific targeted drug delivery system

J regia and T gharuensis attenuated FCA induced arthritis by downregulating of pro-

inflammatory cytokines and upregulating of anti-inflammatory cytokine therefore

plants extracts may be effective in treatment of other inflammatory disorders such as

asthma ulcer gout and acute hepatitis etc

There is a need to further evaluate reproductive mutagenic teratogenic and toxicity

studies of J regia and T gharuensis extracts so as to determine their safe use in special

population groups such as animals of childbearing potential pregnant females and

neonates

Clinical studies are required to evaluate safety and efficacy of extracts on human

population
