title: Evaluation of the chronic hepatic toxicity of 6-mercaptopurine in the wistar rat.
abstract: The ability of choline (C) to prevent hepatic toxicity due to chronic administration of 6-mercaptopurine (6-MP) was evaluated in male Wistar rats. Two dose levels of 6-MP and two dose levels of C were used. Choline did not prevent or diminish the hepatic accumulation of triglyceride when administered in combination with 6-MP. The 6-MP did impair the growth of the experimental animals, and this effect was antagonized by C administration. The data provided experimental support for the clinical observation of growth impairment in children treated with chronic antimetabolite therapy for acute lymphoblastic leukemia.
