Developing standards in animal research review.

Thirty-two institutional animal care and use committees reviewed 4 hypothetic protocols involving experimental procedures frequently conducted on animals. Committees were in general agreement on the need to refine hypothetic protocols to minimize pain, distress, and other harm to laboratory animals. All but 2 committees sought modifications in each protocol, and in numerous instances, committees would not approve a protocol without major modifications. The committee responses delineated emerging standards governing specific areas of animal use, such as antibody production, induced disease, surgery, physical restraint, and behavioral conditioning. Committees had less consensus in their approach to assessing the justification for laboratory animal use. Apparently, this component of committee responsibilities presented the major conceptual and practical difficulties for committees engaged in animal research review.
