[Changing relative proportions of apolipoproteins of VLDL in chronic male alcoholics (author's transl)].

Apoproteins of very low density lipoproteins of plasma from male chronic alcoholics and healthy men serving as controls were investigated. VLDL were delipidated using diethyl ether-ethanol and were separated by polyacrylamide gel electrophoresis. The average relative concentration of apo Cll, Clll1 and Clll2 are investigated. The proportion of apo Cll is reduced, and that of apo Clll increased (particularly Clll1) in male chronic alcoholics compared to the normal and the ratio of apo Clll1 to apo cll was significantly increased. The Cll/Clll1 + Clll2 ratio is highly significantly reduced in patients. Changes in apo Clll1/Cll ratio in relation to hypertriglyceridaemia are envisaged. Furthermore apo Cll is believed to activate and apo Clll to inhibit lipoprotein lipase activity "in vitro".
