Effect of clofibrate feeding on some lipogenic enzyme activities induced by high carbohydrate diet.
Clofibrate administration by stomach tube or intraperitoneally for 3 successive days to rats fed standard diet or starved for 72 hr caused about 2-fold increase of malic enzyme activity in the liver and adipose tissue. The drug administered by stomach tube (but not intraperitoneally) to the rats fed fat free-high carbohydrate diet significantly blocked the inducing effect of the diet on malic enzyme activity in both tissues. Clofibrate blocked the induction by fat free-high carbohydrate diet of hexose monophosphate shunt dehydrogenases and ATP-citrate lyase in the liver. The amount of fat free-high carbohydrate diet consumed by rats received clofibrate by stomach tube was much less than by untreated animals. It is concluded therefore that the significant decrease of food consumption by rats receiving clofibrate by stomach tube is responsible for the inhibitory effect of the drug on some lipogenic enzymes activity induced by fat free-high carbohydrate diet.
