Animal Experimentation
Scientific researchers use animal experimentation for biomedical and veterinary research to enhance human health and possibly the welfare of other animals. They claim that successful medical treatments including antibiotics, vaccines and other drugs have been developed with the aid of animal experiments, and such research a crucial means of investigation of and the development of treatments for serious diseases. Some organisations are completely opposed to all animal experimentation, arguing that medical advances do not justify it. It is important that the effects of drugs can assessed before clinical trials on humans begins. Provided that it is carefully controlled, I do think animal experiments for medical research are justified, as long as it is really necessary and no other type of research is possible. An area that I do strongly disagree with is the use of animals for testing to
Another concern is that, despite stringent controls, some unforeseen effect might occur as the result of genetic manipulation. The possibility of viral contamination is eliminated completely with the use of recombinant factor VIII. Benefits The process of genetic engineering has great potential. Virtually all haemophiliacs who received factor VIII before the mid-1980s have contracted acquired immune deficiency syndrome (AIDS) or hepatitis from viral contaminants in the blood used to make the product. For example, the gene for insulin, needed for treating diabetics, is normally found only in higher animals. Hazards While the potential benefits of genetic engineering are considerable, so may be the potential dangers. Public opinion is against this type of testing as it is seen as cruel and unnecessary, and many products are now sold as 'not tested on animals'. There are many others, frequently supported by charitable donations, for example donkey sanctuaries and hedgehog hospitals. What concerns many people is that the long term effects of consuming such foods cannot be predicted, and consumers have rejected 'GM' ingredients in the foods they buy. Other uses of genetic engineering include increasing the disease resistance of crops, producing pharmaceutical compounds in the milk of animals, generating vaccines, and altering livestock traits. xicity of substances, such as cosmetics and shampoo. Genetic modification What is genetic modification? Genetic engineering is the method of changing the inherited characteristics of an organism in a predetermined way by altering its genetic material, or deoxyribonucleic acid (DNA). For example, genetic modification has been used to improve the texture of a tomato and to make it last longer. Another important use of genetic engineering is in the manufacture of recombinant factor VIII, the blood-clotting agent missing in patients with haemophilia. With genetic engineering it can now be introduced into a bacterial cell.
