Cirrhosis of Choline Deficiency in the Rhesus Monkey. Possible Role of Dietary Cholesterol

One of five rhesus monkeys fed a diet deficient in choline and protein for 31 mo developed signs of cirrhosis at 26 mo. Five other monkeys were fed the same diet for 14 mo, at which time cholesterol comprising 2% of the diet was added. Three followed a sharp rise in hepatic lipids. One monkey developed marked hypercholesterolemia and showed signs of cirrhosis 2 mo after cholesterol supplementation. The findings indicate that the rhesus monkey is susceptible to choline-deficiency cirrhosis. They suggest that cholestrol supplementation accelerates this process.
