The Inhibition of Coronary Atherosclerosis by Estrogens in Cholesterol-Fed Chicks

Abstract

Chronic administration of estrogens parenterally inhibits coronary atherogenesis in cockerels fed a cholesterol-supplemented diet, although no such prophylactic effect was observed against aorta atherogenesis. This protection of the coronary vessels is associated with depression of the plasma total cholesterol-lipid phosphorus ratio toward normal levels consequent upon estrogen-induced hyperphospholipemia.
