title: [Ethics and animal experiments.].
abstract: OBJECTIVE
  This is a major subject since the aim is to grant human beings physical, mental, social and spiritual well-being without forgetting the sacred rights of all animals. Most international codes dealing with health-related research practices state that research developed in human beings should be based on previous lab animal experiments or on other scientific data. This article aimed at explaining ethics in animal experiments.
  
  
  BACKGROUND
  The concepts of dissertation and thesis, experimental thesis, experimental essay or pilot experiment and experimental animal facilities are reviewed. Then, a historical retrospective is drawn about the first attempt to develop experimental research policies during the mid 19th Century, in London. It is highlighted that some criteria defined by that time still persist. The first animal research ethical committee was created in Sweden in 1979, followed by the USA in1984. In Brazil, animal research ethical committees were created as late as in the 90s. The Federal Law 6638 was passed in May 1979 and provides for the didactic-scientific practice of animal vivisection. This law, however, is still waiting for regulation. In addition, there are some drafts being analyzed by the Congress, which provide for the use of animals for teaching and research purposes. Finally, the policies adopted by the Brazilian College of Animal Experiments and the Universal Declaration of Animal Rights are presented.
  
  
  CONCLUSIONS
  Professors, postgraduates, residents and graduate students of a Medical School involved in animal research should be aware of the ethical principles aiming at protecting animals selected for scientific work.
