Using animals for experiments.

New drugs are aimed at humans, but since testing on humans is not possible at the developmental stage, a new method of cloning human receptors and inserting them in an animal or yeast culture has been developed. These human cell lines can be used as screening systems for new drugs. 2) Peter Weeby is studying the organisms, fish and plankton, that live around hydrothermal vents, some of them on the deep sea floor. 3) Millions of diabetics are alive today because millions of dogs died. The Wellcome Trust gave grants of 6̋5m, for over 1000 projects, and over 200 of these used animals for experiments. 90% were rodents. Is animal research still needed? Bridget Ogilvie justifies tests on living animals. Thalidomide demonstrates this perfectly as tests had not been carried out on pregnant animals. Britain has very strict laws on animal experiments. We must continue to produce new antibiotics, to keep pace with bacterial changes, and need to test on animals that the new drugs are non-toxic.
