Brazilian law for scientific use of animals

The Brazilian scientific community claimed for a definitive systematization and for comprehensive and realistic national rules, to provide guidance and regulation, instead of sanctions, so that the question of scientific research involving animals could be better contemplated. This is beginning to occur now with Law n.(o) 11.794, sanctioned by the President of the Republic on November 8, 2008. Purpose: To describe the evolution of Brazilian regimentation for scientific use of animals and to analyze Law n.(o) 11.794. Methods: The legislation about the use of animals in teaching and in scientific research in Brazil and in Rio de Janeiro State was identified and discussed. Results: Until now, there was no updated general and systematizing rule regarding animal vivisection and experimentation for didactic or scientific purposes. The only specific law dates back to1979 and was not regimented. More recent laws equated the practice of scientific experiments to acts of abuse and mistreatment of animals, when alternative technology was available. Municipal laws that restricted the scientific practice of vivisection and experimentation with animals were created in the cities of Rio de Janeiro and Florianopolis. Conclusion: With the claim and collaboration of the scientific community, the sanction of Law n.(o) 11.794 regarding to the scientific use of animals represented an invaluable advance in spite of the presence of some points that eventually may require another type of treatment. The new Law states that it will be regimented within 180 (one-hundred-and-eighty) days, when some of these points could be better elucidated.
