Noncompliance with Public Health Service (PHS) policy on humane care and use of laboratory animals: an exploratory analysis.

The National Institutes of Health (NIH) is a major biomedical research-funding body in the United States. Approximately 40% of NIH-funded research involves experimentation on nonhuman animals (Monastersky, 2008). Institutions that conduct animal research with NIH funds must adhere to the Public Health Service (PHS) care and use standards of the Office of Laboratory Animal Welfare (OLAW, 2002a).

Report of the Working Group on Animal Distress in the Laboratory.

Finding ways to minimize pain and distress in research animals is a continuing goal in the laboratory animal research field. Pain and distress, however, are not synonymous, and measures that alleviate one may not affect the other. Here, the authors provide a summary of a meeting held in February 2004 that focused on distress in laboratory animals.

The HSUS's Pain and Distress Initiative: overview and update.

The Humane Society of the United States (HSUS) publicly launched its Pain and Distress Initiative in 2000, to encourage greater attention to the prevention and alleviation of pain and distress in research animals. The initiative's ultimate goal is the phasing out of all significant pain and distress in animal research by 2020. There have been several developments to date.

A demographic analysis of primate research in the United States.

An analysis of primate research in the USA, including the number and species of non-human primates used, types of research, levels of invasiveness, housing conditions and funding, is an important step in addressing various concerns (ethical and scientific) surrounding primate research. An analysis of monkey and chimpanzee research, conducted by The Humane Society of the United States (HSUS), demonstrated that the USA uses more non-human primates (including great apes) in research per year, than any other country in the world. The US government devotes approximately $575-800 million per year to primate research and care.

Possibilities for refinement and reduction: future improvements within regulatory testing.

Approaches and challenges to refining and reducing animal use in regulatory testing are reviewed. Regulatory testing accounts for the majority of animals reported in the most painful and/or distressful categories in the United States and Canada. Refinements in testing, including the use of humane endpoints, are of increasing concern.
