title: Serum total bile acid concentration in rhesus monkeys: effects of feeding cholesterol and inhibiting cholesterol absorption and synthesis.
abstract: The serum total bile acid concentration was measured in rhesus monkeys fed diets practically free of cholesterol and with added cholesterol at two levels. Also, the effects of inhibiting cholesterol absorption by feeding plant sterols and inhibiting cholesterol synthesis by feeding triparanol upon the serum total bile acid levels were studied. Cholesterol feeding significantly increased the serum bile acid concentration. The serum bile acid level was decreased in the high responders fed plant sterols but only when the diet contained the highest level of cholesterol. In both groups serum bile acid levels were not altered when cholesterol biosynthesis was inhibited by feeding triparanol. It is suggested that cholesterol feeding increases the serum bile acid level probably due to an increase in the intestinal pool of bile acids as a result of increased production of bile acids in the liver and their excretion into the bile.
