Sepsis is a critical condition often caused by bacterial infections, either localized or systemic, can lead to maleinfection and is considered a common cause of morbidity infertility [6]. Apoptosis is a second prominent feature ofand mortality [1]. Sepsis is the biggest obstacle sepsis. This process is a mechanism of tightly regulatedpreventing improvement of the success rate in curing disassembly of cells caused by activation of certaincritical illnesses. It is a systemic inflammatory response specialized proteases called caspases.

DISCUSSION During sepsis the most common injury to the kidney

The present study demonstrated by dilation and congestion of renal blood vessel withhistopathological and immunohistochemical examinations, perivascular inflammatory cells infiltration and thesethat sepia tissue extract and polysaccharides attenuate results agreed with [39, 41, 33]. Activated macrophagessepsis-induced lung, kidney and testis injuries in the rat produce oxygen radicals are responsible for cellular lipidmodel of sepsis. peroxidation, protein oxidation and mitochondrial

We have used surgical operation similar to that impairment function, which cause further damage todescribed by [27] as a sepsis model by cecal ligation and tissues and can induce cell death [42]. Also, Wang et al.puncture (CLP) , which led to persistent fecal leakage from [5] demonstrated that CLP caused an increase in renalthe cecum into the abdomen, thus providing a capillary permeability. The cuttlebone extract showedpolymicrobial source of infection in rats and sudden normal glomerular structure with intact Boman's capsuleenterance of large numbers of pathogens and its toxins and normal renal tubular structures. These results wereinto the peritoneal cavity [30]. The host response towards supported by the findings of Subhapradha et al. [43] thatthese invading pathogens is characterized by systemic cuttlebone extract of Sepia aculeate showed goodpro–inflammatory response that is primarily mediated by antioxidant activity.cytokines , which can lead to fatal multiorgan failure and The testis of sham and cuttlebone extract treatedseptic shock [31]. The histopathological lesions , that groups showed normal histological structure of activewere observed in the Lung , kidney and testis in rats with mature functioning seminiferous tubules, the septic groupsepsis are due to sever bacteraemia and septicaemia that treated with methanolic extract of sepia improvedresult from rapid transfer of septic pathogens and its histological structure of seminiferous tubules, while thetoxins from the peritoneal cavity into the systemic septic group showed degeneration of spermatogonealcirculation . Gram negative aerobes and Facultative cells [44]. Also, it has been documented that ROSanaerobes such as E. coli which considers the most overproduction associated with inflammatory reactionscommon pathogen agents that identified in circulation in may be primarily caused by pathological bacterial strainsman and laboratory animals [32, 33]. that colonize or infect the reproductive tract [45].

The lung is one of the most common organs affected Caspases inactivate proteins that protect living cells fromin sepsis and cellular infiltration, together with the release apoptosis and they contribute to cell death by directof proinflammatory mediators, leads to the development disassembly of cell structures [46]. Cytosolic caspase-3of acute lung injury, characterized by oedema, activation is regulated by both TNF- receptor mediatedhemorrhage, destruction of alveolar wall with severe extrinsic and intrinsic apoptotic cascades (12). In theinfiltration of inflammatory cells and these results agreed different pathways inducing apoptosis, caspase-3 appearswith [34, 35, 36]. Loss of endothelial barrier integrity to play a central role as most pathways result in theresults in increased capillary permeability and the activation of caspase-3 [47]. Additionally, in situproduction of interstitial and alveolar edema [37]. It is now localization of cleaved caspase-3 has found some favorwidely accepted that the formation of inflammatory for histological labeling of cells in apoptosis [12, 33].mediators plays an important role in the pathophysiology Based on these data, we used caspase- 3of inflammation in acute lung injury [38]. Apoptotic cells immunohistochemical staining for determining theand bodies are recognized by specific surface receptors of apoptosis in pulmonary, renal and testicular tissues.tissue macrophages and digested [39]. Based on these The cytoplasm and the nucleus of pulmonary and rounddata, we could conclude that the increased mononuclear cells in the lung of the Septic group showed strongcell infiltration in lung tissue in sepsis group compared caspase-3 immunopositive reaction, this result agreedwith the other groups in the present study may be with Ozdulger et al. [26], they demonstrated septic lunginvolved in sepsis induced tissue inflammation and high injury through strong caspase-3 immunopositive reactionapoptotic activity. Another recent area of interest in the in rats. The nuclei of renal tubular epithelial cells of thepathogenesis of lung injury is the role of reactive oxygen Septic group showed strong immunopositive reaction,species . Apart from direct cytotoxic effects, reactive agreed with Messaris et al. [13] they investigated theoxygen species have important effects on the apoptotic death of renal tubular cells in rat CLP model ofinflammatory response mediated via changes in sepsis and Koca et al.
