1. 1. Desiccated thyroid has a partial inhibitory effect on cholesterol-induced hypercholesterolemia and atherosclerosis in the chick. It also lowers the hyperphospholipidemia and hyperlipemia of cholesterol-feeding, decreases aortic cholesterosis, and is effective as a lipotropic agent against the cholesterol-type fatty liver. 2. 2. By contrast, the hypermetabolism-inducing agent dinitrophenol has little or no effect on plasma or tissue lipid levels. It is also ineffective as a prophylactic agent against cholesterol-induced atherosclerosis in the chick. 3. 3. It is concluded that the effects of thyroid on lipid metabolism and atherosclerosis are not mere nonspecific by-products of the induced generalized increase in metabolic rate. Thyroid hormone and the lipids appear to be closely linked metabolically. The hormone apparently influences cholesterol metabolism and atherosclerosis via specific intermediate biochemical reactions in which it participates. 4. 4. Cholesterol-induced atherosclerosis in the chick may develop with little or no increase in the hepatic total cholesterol concentration.
