The scientists, Judith Thomas and Juan Contreras, formerly at the University of Alabama at Birmingham (UAB), falsely reported that they performed double kidney removals on several rhesus macaques in experiments designed to test the effectiveness of two immune suppressing drugs -- Immunotoxin FN18-CRM9 and 15-deoxyspergualin (15-DSG) -- in preventing rejection of a single transplanted kidney. The experimental protocol was to remove one intrinsic kidney, replacing it with a transplant and starting the monkeys on immunosuppresants, and then remove the other intrinsic kidney a month later, according to Richard Marchase, UAB's vice president of research.
