Final answer:
Dr. Nathan Brewer led the group of veterinarians that formed the Animal Care Panel in 1950, which is now known as the American College of Laboratory Animal Medicine. The ACP's legacy continues through the IACUC, which oversees the ethical use of animals in research and ensures compliance with federal regulations.
Step-by-step explanation:
The group of veterinarians that met in Chicago and formed the Animal Care Panel (ACP) in 1950 was led by Dr. Nathan Brewer. The ACP eventually evolved into what is known today as the American College of Laboratory Animal Medicine (ACLAM). Following the principles set by ACP and further reforms, at the local level, any facility using animals and receiving federal funding must have an Institutional Animal Care and Use Committee (IACUC). The IACUC ensures that the National Institutes of Health (NIH) guidelines are followed and includes a diverse group comprising researchers, administrators, a veterinarian, and at least one person not affiliated with the institution, ensuring ethical considerations in animal research. This committee is pivotal in overseeing and inspecting laboratories as well as research protocols involving animals, aligning with regulations such as the Animal Welfare Act (AWA) and the Public Health Service (PHS) Policy on Humane Care and Use of Laboratory Animals.
