[Animal protection and animal experiment from the viewpoint of biomedical research].

Animal protection societies have recently launched strong attacks on the nature and extent of animal experiments in medical research and proposed measures in national parliaments to prohibit all experiments with animals. Scientists engaged in research with animals should examine their own research in the light of these criticisms, and give detailed reasons for the necessity of their investigations. In addition, they should be more concerned with the rectification of false conceptions and statements about the execution and objectives of animal experimentation. This involves explaining the nature and limits of the so-called alternative methods which are requested by animal protectionists as substitutes for experiments with live animals. Improvements in the conditions for research and the upkeep of laboratory animals at the universities during this decade have reached a high level. With the introduction of animal protection laws, uniform regulations have already been achieved in various countries and such regulations will soon be operative in Switzerland. Nevertheless, an open and objective dialogue between animal protectionists and scientists is desirable at this stage of the confrontation, with a view to clarifying their different viewpoints and objectives and searching for solutions.
