The Importance of Animal Experimentation for Safety and Biomedical Research

Scientists are coming under increasing pressure from activist groups to stop animal experimentation, branded as cruel and unnecessary for improving human health. This attitude, however, stems from an unrealistic evaluation of the situation and distorted information about present scientific knowledge. There is no question that most medical progress - perhaps all, in fac- has been attained through knowledge derived initially from experiments in various animal species. There is practically no way of replacing animals in these investigations and so-called 'alternative methods' are in reality merely complementary. Tissue cultures, cell, microorganisms, enzymes, membranes, mathematical models - all are useful for preliminary screening tests and for testing hypotheses, but the complexity of a living organism is such that in vivo studies are essential before any test can responsibly be made in man. This book presents the proceedings of an international symposium organized in Strasbourg (October 24-25, 1988), with the aim of assessing present-day requirements as regards animal experimentation in research related to major medical and toxicological problems still awaiting solutions.
