Rights, Suffering, and a Cure
What do you think of when you hear the phrase animal rights? Do you think of crazy
activists breaking into laboratories and letting all the animals free? Or do you think of the
horrible pictures of animals suffering from chemical injections? Do you see animals being forced
to fight one another to the death? Do you think of die hard vegetarians who protest in front of
slaughter houses? All of those things are just small aspects that make up the larger picture of
animal rights. They are all equally important in their own way, but the animal rights issue that
hits home is the use of animals as product testing subjects. This issue bothers me the most
because I have three dogs and I would be horrified if anything ever happened to them. And the
thought of the things Ive seen in pictures happening to my dogs outrages me.
There are people out there who strongly feel that animal testing is inhumane and maybe it
is, but there is more to it that. Animal testing is the experimental use of non-human animals. The
main types of products scientists test include: house hold products, cosmetic products, and
pharmaceuticals. Some pharmaceutical products include HIV/AIDS drugs and vaccinations for
other diseases. To develop these pharmaceuticals animals are tested to see whether a new drug
will have an effect on the disease and whether the effect will be serious (Grinning Planet). And
to test the medicines and get results scientists use tests like the Mutagenicity test where
chemicals are administered into the bone marrow of the test animals. They also use the
Pharmacokinetics/Toxickinetics and Metabolism test which measures the rate of how fast they

absorb the chemical, how long it takes their metabolisms to work it out of their systems, and how
fast they sweat out the chemicals (American Anti-Vivisection Society). However, pharmaciticals
are not the main problem, cosmetic and household products are because ninety-four percent of
animal testing is done to determine the safety of cosmetics and household products (Animal
Testing).
Some household products that are tested on animals are bleach, washing-up liquid,
laundry detergent, insecticides, solvents, furniture polish and air fresheners (Testing Household
Products on Animals). To test these products they use tests like the Acute Toxicity test which
exposes the animals to a chemical by mouth, skin, or inhalation; or the Repeated Dose Toxicity
test which is used to evaluate chronic toxic effects on organs by orally taking a substance,
inhaling a substance, or placing a substance on the skin (American Anti-Vivisection Society).
There are also cosmetic products like eye shadow, eye liner, blush, hair spray, and
perfume that are tested on animals to see if they go blind or have some type of cornea damage.
They also expose animals to the chemical to see whether they develop skin irritations or get sick
(Grinning Planet). To test these skin based products scientist use the Skin Corrosivity test which
involves placing a chemical on a shaved patch of skin and using another shaved patch as a
control, and the Skin Sensitization test where substances are applied on the surface or injected
onto the animals shaved skin (American Anti-Vivisection Society). Cosmetic products,
household products, and pharmaceuticals are products that people use every day, products they
pick up in the store without even realizing how they are made; without even realizing that when
they buy them they are becoming a part of the reason that animal testing exists. And the way
these animals are tested for us to receive these products is inhuman and unnatural but scientist
use them because they have qualities that make it easy to observe the affects of the substances.

Most scientist and companies are only worried about the results so they use the animal
that they think will get them the best results which leads to many different animals being used.
Rabbits are used in the Draize Eye Irritancy Test because of their big eyes which make it easy to
observe the effects of the chemicals. In Acute Toxicity test rats and mice are most commonly
used because it is easy to perform a necropsy on them to see internal organ damage. Rats are also
used in tests like Pharmacokinetics/Toxicokinetics and Metabolism and Dermal Penetration
because it is easy to kill them and examine their insides. Guinea pigs are used in Skin
Sensitizations tests because it is easy to see the chemical reaction on the skin (American Anti-
Vivisection Society). Other animals used for product testing include dogs, cats, nonhuman
primates, and farm animals.
The way these tests affect these animals is something that humans cannot even begin to
imagine. The Draize Eye Irritancy Test uses household products, shampoo, pesticides, weed
killers, and riot control gases (Testing Household Products on Animals). The substance is
sprayed or put in the eye of an albino rabbit. No pain relief is given and the test goes on for about
seven days. The scientists look for signs of opacity, ulceration, hemorrhage, redness, swelling
and discharge. The testing of Acute Toxicity in animals is dangerous and sometimes deadly. The
test requires poisoning large numbers of animals in Lethal Dose 50 (LD50), which is conducted
until at least one half of the test animals die (Leeuwen, and Vermeire 240). In tests done for
cosmetics and pharmaceuticals test animals may develop tumors or other nasty conditions, and
are often killed intentionally at some point in the test so scientists can examine the animals'
innards for signs of damage (Grinning Planet). These tests did not crop up of their own accord
humans created them for a reason.

If animal testing continues more and more animals will be born just for the sake of testing
products, which is just as bad as puppy mills. The poor, innocent, abandoned animals from the
pound will continue to be used in the laboratory as test subjects. That doesnt need to happen
because animal testing can become a thing of the past because it is ineffective. For example, the
Draize Eye Irritancy test has often been condemned on scientific grounds because it produces
unreliable results which can bear little relation to human responses (Stop Testing Household
Products on Animals). According to Kelly Overton, an animal rights activist, we spent billions
of dollars to cure cancer in mice, but so far have failed to replicate human cancer in any animal,
let alone close in on a cure. Animal testing has proved to be unnecessarily painful and studies
have shown that these tests are ineffective, so there is no legitimate use for animal testing. So
why do we human subject animals to it? Because animals were the only option people saw at the
time, but thats not true anymore. There are new and more effective alternatives out there now.
One of those alternatives is cell culture the process by which a cell is grown under
controlled conditions. It is used in the 3T3 Neutral Red Uptake Phototoxicity Test to assess the
potential for sunlight-induced (photo) irritation to the skin (PETA). And the test systems based
on continuous cell lines have the exclusive advantage that they do not have to use animals in
experiments. The test has relitivly low cost rate and is very beneficial because it gives
researchers information that relate directly to humans. However, they lack the interaction
among different regulatory mechanisms and pattern formation in embryogenesis which are
crucial to development (Alderth H. Piersma). It also does not work because the researchers
cannot see the effects of the substance in a living body.
Another possible solution is to use that Murine Local Lymph Node Assay. Some
scientists believe that it will become new and effective way of testing products instead of animal

testing. Murine Local Lymph Node Assay is used as an alternative to guinea pig tests that screen
for allergic reactions on the skin. The LLNA tests, reduces animal use as well as pain and
suffering; it is also faster and provides dose-response information (AltTox). But the big problem
is that even though the protocols test with such specificity now that it requires far fewer animals
for testing than previous protocols it still doesnt stop the use of animal testing all together, it
only switched to using mice instead of guinea pigs. It also does not give enough accurate
information about the living systems of the human body.
The Rat Skin Transcutaneous Electrical Resistance tests are also a possible solution. The
European Center for the Validation of Alternative Methods believes that it is highly effective and
useful. They test two endpoints following the exposure of isolated rat skin for 2-24 hours to a
test chemical: changes in the transcutaneous electrical resistance and the binding of a dye,
sulforhodamine B (AltTox). The test is more humane because it no longer uses live animals to
test chemicals, but it still has a flaw. To get the rat skin that is used in the test scientist end up
killing the rats. Even though the rats are humanely killed, animals are still being killed in the
process and the purpose of an alternative is to stop the misuse of animals. And killing them for
their skin is defiantly abusing them.
Animal testing is dangerous and ineffective which is why we should use an alternative
method known as EPISKIN. It is an artificial skin, a human epidermis reconstructed on collagen.
EPISKIN can be, manipulated and adapted based on the tester's needs: it can be made to
resemble older skin, can be made to tan and, by using donor cells from women of different
ethnicities, can assess the efficiency of sunscreen for various skin tones ( Jeremy Elton
Jacquot). The ICCVAM and the European Center for the Validation of Alternative Methods have
both authorized the use of the EPISKIN test. And many scientists are saying that it could

potential stop all animal testing sometime in the future. That is the best way to go, humans dont
have to worry about using human subjects or animal subjects and the product companies and the
FDA still get the same response they wanted. However, there are those people out there who still
feel iffy about it. Some people feel it cost to much and all companies can afford it. Well animal
activist groups like PETA and the AAVS could help pay for the creation of this new skin. Or the
government could pitch in and help foot some of the bill. There are many way that we could
make it easier to pay for the skin. There are also some people out there wondering if the product
will even work for other types of tests. EPISKIN is still in the testing phase, but according to the
European Center for the Validation of Alternative Methods sometime in the future the
government will make it mandatory for the drug, food, and chemical industries to start using it
(Jeremy Elton Jacquot).
When you hear the phrase animal testing what do you think of? I know I dont think of
it the same way I use to. I use to see animal testing as scientist injecting various chemicals into
animals and rabbits were the main subject. But I have learned that animal testing is much more
than that. It is subjecting animals to potentially dangerous chemicals and substances. It is
spraying defenseless rabbits in the eyes with harmful solutions and initially inflicting pain on
them without providing relief. Subjecting them to lethal chemicals until half of them die and then
killing the rest to see how they were affected. Animal testing is cruel and ineffective. That is why
several scientists and companies have come up with several new types of alternative methods for
animal testing. However, not all of the methods they came up with are something people should
start using because they do not all work the way they should. A good portion of them still use
animals just a lower number of them and some of them are ineffective. But one test stood out
among the rest, the EPISKIN test. Its a win-win situation that makes everyone happy, it gets the

out of laboratories.
