Animal
Testing
Behind medicines
and cosmetics that people are using in everyday life, there are a great number
of animals suffering from great pains and itchiness imposed by humans.

Today, approximately
100 million of animals are used for Animal Testing around the world (NAVS). Animals
are sacrificed for experiments as counterparts of humans and the purposes of these
testing can be classified into three main categories―to
advance scientific research, to study diseases and develop medicines, and to
confirm the safety of chemicals contained in products such as food or cosmetics.
Owing to these researches, people could discover effective preventives and
treatments for diseases such as rheumatoid arthritis, polio and hepatitis C. Also
the results of animal testing have also been prevented people from facing
harmful effects of products (NCB).
It is true that animals can be useful
models for studying specific aspects of human biology and diseases and the
likely effects of chemicals and medicines in humans. However, many people are ignorant
of potential risks of those outcomes experimented upon animals. Also, for the experiment,
animals are inflicted with great suffering given by people―for
example, they are force to have chemicals which might have toxicity, or they
are genetically engineered to have specific diseases which scientists want to
study(JAVA). It is obviously what people call animal abuse. In order to conduct
more reliable research and to improve treatment of animals involved in Animal
Testing for products, Japanese government should obligate companies 1) to
promote its treatment according to the principle of “3Rs” (Replacement,
Reduction, Refinement)and 2)to improve the availability of information related
to Animal Testing.
Animal testing involves two main
problems: biological difference between human and animals, and artificial
process to make animals ill. First problem, biological difference between human
and animals is most common argument against animal testing. According to Japan
Anti-Vivisection Association (JAVA), one of the Japanese non-profit
organizations against animal experiment, even though human and animals share
same DNA to some extents, there are specific differences such as body structure
and metabolic activity. JAVA claims that these specific differences greatly affect
the results of testing and those results are not reliable enough to apply to
human beings. There are a lot of evidences that supports JAVA’s view―For
instance, the widely prescribed arthritis painkiller called Vioxx was considered
to be safe and even beneficial because of the positive result achieved by
animal testing on mice. However, Vioxx was withdrawn from the market around the
world in 2004 because it caused heart attacks and strokes to approximately
320,000 people and 140,000 of them have died (MRMC). Another instance is the
case of the drug called monoclonal antibody (TGN1412).This drug was tested on
monkeys and though to be harmless since it did no harm on monkeys even 500
times the dose were given to them. However, when six human volunteers who participated
in the clinical trial were given a dose of the drug, all of them became fatal
(BUAV). From these instances, it is obvious that the results gained by animal
testing cannot be applied to human because it has possibility to cause harmful
side effects on humans. On the other hand, there are many scientists who
realized problems caused by specific differences and try to use chimpanzees as
a model for human biology because humans and chimpanzees share 98.4 percent of
their DNA and almost same creature. However, Andre Menarche, expert of animal
testing and former president of Doctors and Lawyers for Responsible Medicine in
UK, argues that the tiny difference in DNA is huge in terms of biological
effects. According to Menarche, chimpanzees are immune to fatal human diseases
such as HIV/AIDS, Hepatitis B and Malaria.
Artificial process to make animals ill
is the second scientific problem of animal testing. According to JAVA, the data
of animal testing cannot be applied to humans because humans’ diseases are
caused by complicated factors such as living environment, diet, inheritance and
stress.
Nice work so far, Kana. 24 hours prior to your tutorial, try to update this (add more about your solutions and add your Works Cited etc.). Talk to you next week!
