vivisection (redirected from Vivisections)

vivisection (vĭv'ĭsĕk`shən), dissection of living animals for experimental purposes. The use of the term in recent years has been expanded to include all experimentation on living animals, rather than just dissection alone. The practice contributed to the outstanding progress that was made in the 17th cent. by William Harvey in understanding the circulation of the blood. However, the use of research animals in the laboratory did not become widespread in Europe until the 19th cent. In 1896, when the National Institute of Health originated in the United States, it began to take an active role in encouraging proper care and use of laboratory animals. Since 1945, the National Society for Medical Research has tried to explain to the public the nature and necessity of experimental procedures on animals. During the 1980s, the incidence of vandalism, harassment, and theft in research centers using animals for testing increased greatly. Most nations have government agencies that assume advisory or regulatory roles in the practice of vivisection. Private organizations in the United States concerned with vivisection include the American Society for the Prevention of Cruelty to Animals (ASPCA), the National Anti-Vivisection Society (NAVS), and People for the Ethical Treatment of Animals (PETA). In the United States today, strict rules and procedures, laid down by the National Institutes of Health and a number of other public and private organizations, ensure ethical and sensitive use of animals for research. The U.S. Department of Agriculture's (USDA's) Animal Welfare Regulations are among the most important documents setting forth requirements for animal care and use by institutions using animals in research, testing, and education. Regulations have been effective since 1985. Members of the Institutional Animal Care and Use Committees observe and enforce compliance to these rulings on institutional levels. The USDA regularly inspects all institutions that use animals for experimental purposes. Animals most frequently used in the laboratory include rats, mice, guinea pigs, rabbits, and monkeys. When animals more closely resembling humans in size and structure are needed, dogs and chimpanzees may be utilized. Animal experimentation is especially advantageous if offspring of several generations are to be observed: for instance, about 5 generations of mice can be observed in a year, whereas in humans the same experiment would require over 100 years.

vivisection

Operation on a living animal for experimental rather than healing purposes; more broadly, all experimentation on live animals. It is opposed by many as cruelty and supported by others on the ground that it advances medicine; a middle position is to oppose unnecessarily cruel practices, use alternatives when possible, and restrict experiments to necessary medical research (as opposed, for example, to cosmetics testing). Surgery on animals without anesthesia was once common; many people, most significantly Rene Descartes, claimed that animals did not really feel pain. Testing chemicals on animals to find the lethal dose still occurs despite alternative methods (computer simulations, tissue culture tests). An antivivisection movement in the late 19th century broadened its scope to include prevention of all cruelty to animals and later gave rise to the animal rights movement.
