ANIMALS IN RESEARCH: THE BIOMEDICAL MODEL

1. Although in modern times the practice of veterinary medicine has been separated from that of human medicine, the observations of the physician and the veterinarian continue to add to the common body of medical knowledge. Of the more than 1,200,000 species of animals thus far identified, only a few have been utilized in research, even though it is likely that, for every known human disease, an identical or similar disease exists in at least one other animal species.

2. Veterinary medicine plays an ever-increasing role in the health of man through the use of animals as biomedical models with similar disease counterparts in man. This use of animals as models is important because research on many genetic and chronic diseases of man cannot be carried out using humans.

3. Hundreds of thousands of mice and monkeys are utilized each year in research laboratories in the U.S. alone. Animal studies are used in the development of new surgical techniques (e.g., organ transplantations), in the testing of new drugs for safety, and in nutritional research. Animals are especially valuable in research involving chronic degenerative diseases because they can be induced experimentally in them with relative ease. The importance of chronic degenerative diseases, such as cancer and cardiovascular diseases, has increased in parallel with the growing number of communicable diseases that have been brought under control.

4. The study of animals with diseases similar to those that affect man has increased knowledge of the diseases in man; knowledge of nutrition, for example, based largely on the results of animal studies, has improved the health of animals, including man. Animal investigations have been used extensively in the treatment of shock, in open-heart surgery, in organ transplantations, and in the testing of new drugs. Other important contributions to human health undoubtedly will result from new research discoveries involving the study of animal diseases.
