Introduction Animals have been used for pharmaceutical testing throughout history. The Greeks in early BC were the first to carry out animal testing using live animals to test experiments and different medicines on. (en.wikipedia.org/wiki/History_of_animal_testing) Animal testing has provided many positives to human lives but is still a controversial issue. Some people believe that animal testing is unnecessary and alternatives should be considered. Others believe animal testing is essential to find if certain drugs are harmful to humans. Biology Animal testing involves testing pharmaceutical drugs on animals in order to see the effectiveness and side effects of the drug. This is usually carried out by inhaling, inserting or placing the drug on the animal’s skin. Two regular tests conducted are the LD50 test and Draize test. LD50 is a common animal test which stands for the lethal dose (LD) which will kill 50 per cent of the animals being tested in a certain amount of time. It involves the testing substance usually placed in the animal’s mouth via a tube. Animals are observed over a series of days to determine which dose of substance. LD50 is most commonly tested on rats and mice and is used to test drugs, agricultural chemicals, cleaners, and some cosmetics. (www.ccohs.ca/oshanswers/chemicals/ld50.html#_1_1) Draize test is an eye or skin irritancy test usually conducted on rabbits to determine if the pharmaceutical is safe by placing a substance on the skin or eyes. The rabbits are seized with restraints and their eyes are held open so they are unable to blink and wash the chemical out. The effects of the pharmaceutical are observed over the following days to see if any irritation or reactions occurs.( Vicki Katrinak,... ... middle of paper ... .../1/2 - Author Unkown, 2010,‘The Scientific Argument Against Animal Testing’ viewed 17 May 2010, www.whitecoatwelfare.org/aat-text.shtml). - Author Unknown, 2010, ‘How are Laboratory Animals Used’, viewed 20 May <2010 altweb.jhsph.edu/resources/faqs.html#3> - Cook, Kristen, 2006, ‘Pro-Test: supporting animal testing’ viewed May 17 2010, http://www.spiked-online.com/articles/0000000CAF94.htm - Katrinak, Vicki,2007, ‘Rabbits Used in Product Testing’, viewed 19 May 2010 < www.aavs.org/testingTypesBlinded.html> - Parent, Jason, 2010, ‘Is Animal Testing in Scientific Research Needed?’ viewed - Singh, Sonu, 2009, ‘Is There a Substitute for Animal Testing?’ viewed 26 May 2010,
The Draize and LD50 are the most common use and cruel experiments (Siegel-Maier). What Draize is a eye irritancy test. To perform a Draize experiment the animals head is secure so it won’t move and the substance is drop into the animals eye and the results are recorded . The animals eye is hold shut for 3 to 21 days. This test are only fifty percent accurate (Siegel-Maier). The Lethal Dose in 50 (LD50) is where animals are forced fed to find out the toxicity levels of substances. The test is finish when half the test subjects are dead. Some of them take as long as a month to die. The results gather from this experiments only “demonstrate the amount of a specific substance necessary to kill a dog or rabbit, not a human being” ( Siegel-Maier). This test are the most common use and yet not very accurate.
Every year about 241,000 rabbits are tortured in United States laboratories to test for the effects that household products, such as cosmetics, dishwashing liquid, and drain cleaner will have on their eyes ("Rabbits in Laboratories | PETA.org." 1). Scientists will drip chemicals into the eyes of the animal to see how much irritation it will cause, a process known as the Draize eye irritancy test ("Rabbits in Laboratories | PETA.org." 1). The test is certainly not pain free; it often causes distress, such as redness, swelling, and sometimes blindness. After the rabbits are finished being toyed with, they are killed ("Rabbits in Laboratories | PETA.org." 1). The Draize eye irritancy test is just one of the thousands of examples of profuse animal testing that has been going on for centuries. Mice, rats, dogs, pigs, cats, fish, birds and primates are tested every day by human beings in an attempt to learn more about the functions of our own bodies ("Update: Animal Testing" 2).
There are many pros and cons to the practice of animal testing. Unfortunately, neither side pleases everyone- including the general public, government and scientists. Animal testing is a process that has been going on for centuries for many different reasons; finding drugs and treatments to improve health and medication. Many medical treatments have been made possible by animal testing, including cancer, HIV drugs, insulin, antibiotics, vaccines and many more. Scientists usually use animals for testing purpose because they are considering similar to humans. Animals have their differences, and are also similarities. This is what comparative medicine is about: researches use both similarities and differences to gain insight into the many complex human biological systems.
In conclusion, animal testing is cruel and unnecessary. Scientists realize that testing drugs on animals is inaccurate and useless. "A growing number of doctors and scientists worldwide are pointing out the fact that animal research is totally useless and that its misleading results frequently prove counter-productive and damaging to human health."(The Human Victims: Animal-based Medical Research) Medical testing on animals is useless and should be stopped. The results from testing on animals is usually inaccurate and it is unnecessary to test on innocent animals.
Some animals that are tested on are being abused and not getting their fare treatment of social activities and some of the people testing them aren’t even being fed and if some animals miss behave the people with inject poison into one of the animals they’re testing on and will kill them and don’t really care because they can always just go get more.
The history of animal testing is a long and controversial one. Early Greek physician-scientists Aristotle (384 – 322 BC) and Erasistratus (304 – 258 BC), to name a couple, performed experiments on living animals. Galen (129 – 199 / 217 AD), also a Greek physician, practiced in Rome and was very important in the history of medicine. He conducted animal experiments to advance the understanding of anatomy, physiology, pathology, and pharmacology. In twelfth century Moorish Spain, an Arab physician by the name of Ibn Zuhr was the first to use animal testing as an experimental method for testing surgical procedures before using them on human patients. William Harvey was an English physician during the 17th Century. He experimented with many animal species aiming to demonstrate blood circulation. In 1859, Charles Darwin's evolutionary theory reinforced th...
There are many positive benefits to Animal Experimentation. It has been said that “not testing new pharmaceutical products on animals is highly dangerous” (HIV and AIDS Information and Resources). Many tests that are done on Animals and then released for the general use are; “Acute toxicity tests consisting of the administration of a single dose of a chemical at a concentration great enough to produce toxic effects and death. An example of such a test is the Lethal Dose 50 (LD50) test in which 50 per cent of the subjects in an experimental sample are expected to die. Biological screening tests designed to determine the biological activity of organic compounds in experimental animals. Carcinogenicity tests where animals, usually rodents, are exposed repeatedly during their life to potential carcinogens (cancer-causing agents). Developmental and reproductive toxicity tests consisting of several procedures designed to assess the potential of chemicals to induce miscarriages or to cause infertility or birth defects, usually in rodents and rabbits. Eye and skin irritation tests are designed to determine whether a particular chemical or product will cause irritation on handling or exposure. The notorious Draize test, in which ra...
"The yankee Veterinary Medial Association defines ANimal pain as an unpleasant sensory and emotional expertise perceived as arising from a particular region of the body and related to real or potential tissue damage" (Orlans 129). Animals feel pain in several of constant ways in which humans do; in truth, their reactions to pain area unit virtually identical (both humans and animals scream, such as). once animals area unit used for product toxicity testing or laboratory analysis, they're subjected to painful and sometimes deadly experiments. 2 of the foremost ordinarily used toxicity checks area unit the Draize check and also the LD50 test, each ofwhich area unit notorious for the extreme pain and suffering they inflect upon experimental animals. within the Draize check the substance or product being tested is placed within the eyes of AN animal (generally a rabbit is employed for this test); then the animal is monitored for harm to the tissue layer and alternative tissues in and close to the attention. This check is extremely painful for the animal, and visual defect, scarring, and death area unit typically the tip results. The Draize check has been criticized for being unreliable and a unnecessary waste of animal life. The LD50 check is employed to check the dose of a substance that's necessary to cause death in one-half of the animal subjects among an explicit quantity of your time. to try and do this check, the researchers hook the animals up to tubes that pump Brobdingnagian amounts of the check product into their stomachs till they die. This check is very painful to the animals as a result of death will take days or maybe weeks. in line with Orlans, the animals suffer from "vomiting, diarrhea, paralysis, convulsion, and internal hurt. Since death is that the needed terminus, dying animals aren't place out of their misery by euthanasia"
The optimistic viewpoints for animal testing are that it assists researchers in finding drugs and treatments to advance health and medicine. It is a legal requirement in most countries for drugs and vaccines to be tested in animals to ensure safety. The world would be a different place if animal research for medical purposes were done away with hundreds of years ago. Today many medical treatments have been made possible by animal testing, including cancer and HIV drugs, insulin, antibiotics, vaccines, etc. Animal testing and research is considered very important for improving human health; in fact, the scientific community and some of the general public support animal research. There are also groups of individuals who are against animal testing for cosmetics but they defend animal testing for medicine and the development of new drugs for disease.
Animal testing should be banned for unnecessary tests because why would the government want to put human through the same thing that the animals go through. Animals should not be guinea pigs to the horrible tests that the scientists run on them. The animals should be able to be free and not have to be strapped down and forced-fed. Animals feel the pain just as well as a human would, but a human can walk away from the pain and say “no”. Sometimes it is better to run tests on animals to find a cure for cancer, HIV, and other diseases but the government and the scientists should find a different way to do this with out killing so many animals.
...ch in Latin translates to “in glass”) methods, have provided versatility to safety testing. This is because in vitro methods can isolate tissue or cell components from either animal or human participants. In doing so, these assays can better predict the activities of drugs, antibiotics, vaccines, and chemicals in relation to human use (Rangantha & Kuppast, 2012). Moreover, the preparation and study involved in in vivo assays, or procedures that use whole organisms, is more complex than their in vitro counterparts. In particular, toxicity measurements in animals requires exposure to and ingestion of potentially lethal substances until 50% of the group dies off (Rangantha & Kuppast, 2012). This test, known as the Lethal Dose 50, has been replaced by the use of donated human tissue. By using human tissue it is also possible to detect toxic effects on human organs.
One of the many painful tests administered on animals in laboratories is the Draize Test. This experiment, introduced forty-five years ago by FDA toxicologist John H. Draize, "is used to measure the harmfulness of chemicals found in household products and cosmetics by observing the damage they cause to the eyes and skin of animals" (Products, 1, 97). The brutal result of these series of tests (usually on rabbits) leaves animals with mutilated, blind, or ulcerated eyes. At the end of these immoral tests, the animals are all killed to study their internal anatomy. (Products, 97)
Animal testing is an act of barbarism, the fact that animals are being bred to be a victim of crude experiments and then euthanized is cruel. An Eye Irritancy Test is a test in which albino rabbits have a substance entered into their eyes that are held open with clips for seven to eighteen days. The rabbits are confined in stocks with only their heads protruding while experimenters record the damage of the eye tissue which can vary to being swollen eyelids, inflamed irises, ulceration, bleeding, massive deterioration, and blindness. Many rabbits break their necks as they struggle to escape from the pain. Another savage test is an Acute Toxicity Test, also known as lethal doses, or poisoning tests. This test determines the amount of a substance that will kill a percentage of a group of test animals. Substances are forced into the animal’s body by tubes to the stomach, cuts to the throat, introduced to the eyes, mixed into food or inhaled through a gas mask. Reactions to this test can include convulsions, heavy breathing, diarrhea, constipation, emaciation, contortion, skin eruptions, and bleeding. The testing period continues until at least half of the animals die, approximately two to four weeks. Keep in mind, anesthesia is absent during these procedures.
To predict the effect it will have on humans, many different tests are performed on animals. A test created by John Draize, called the Draize eye test, is tested for eye irritancy. This test looks for the damage that chemicals may cause to the eyes. During the test, a substance is placed in a rabbit’s eye and the rabbit is observed in intervals. There are many consequences such as bleeding, ulcers, and blindness for up to three weeks and may even result in the death of the animal (aavs). Of the several experiments performed on animals for research purposes, they all appear to affect the animal
Doctors, nurses, animal care personnel, veterinarians, farmers, conservation managers, teachers, zoo keepers and others engaged in animal-related activities all benefit in animal research to broaden their knowledge. Testing is done as a check on the safety of new drugs or substances for human or animal use, and to check whether new batches of drugs and other agents like vaccines work. There is a legal requirement to test how safe and effective chemicals, drugs and other agents are before they can be sold.
