[Influence of radiation on plasma lecithin-cholesterol acyltransferase in rats].
Plasma cholesterol and lecithin-cholesterol-acyltransferase activity are studied in irradiated rats. Ionizing radiations cause an increase of cholesterol levels in plasma, concerning mainly ester fraction. Lecithin-cholesterol-acyltransferase activity in plasma of irradiated rats is diminued 48 hours after exposure. This decreased rate of LCAT is probably the consequence of the post-irradiation hypercholesterolemia.
