The effects of mazindol which is known as a anorexigenic agent on the free fatty acid metabolism in the brain were studied. One-half mg of mazindol was orally administered to rats weighing 500 g for 5 days. Body weight was reduced by 10%, compared to the control. Serum levels of free fatty acid, triglyceride, total cholesterol and phospholipid were decreased. The effect of mazindol on the incorporation of [ 1-14C] palmitic acid into various lipids in the brain were studied. When mazindol (5 mg) was administered one hr before injection of [1-14C] palmitic acid to the internal carotid artery of rats ad libitum, incorporation of [1-14C] palmitic acid into free fatty acids in the cerebrum and diencephalon was lower than that of the control, but incorporation into phospholipid and triglyceride were higher than that of the control. When mazindol was injected into fasting rats, incorporation into free fatty acid in cerebrum and diencephalon was increased compared with the control, and the incorporations into phospholipid and triglyceride were decreased.
