HDL-subfraction was studied in blood serum of drinkers after alcohol intake and control group of men-nondrinkers. Blood serum incubation with fibroblasts culture did not indicate principal differences between drinkers and nondrinkers both with normolipemia and hyperalphacholesterolemia. Increase of HDL2 and decrease of HDL3-subfraction were observed. Incubation of the same species with hepatoma cells culture (Hep G-2) demonstrated significant differences between normolipemia and hyperalphacholesterolemia. The reduction of HDL2 subfraction level and increase of HDL3 have been found in nondrinkers with normolipemia. The raise of HDL2 was demonstrated in hyperalphacholesterolemia (due to HDL2b and HDL2a in drinkers and HDL2a in nondrinkers). Besides, in several samples of normolipidemic blood serum taken after alcohol abuse the changes of HDL-subfractions were identical to those receiving in hyperalphacholesterolemia. It is postulated that one of the mechanisms of the alcoholic hyperalphacholesterolemia development is the decline of the transfer rate of cholesterol ethers to the liver and accumulation of HDL2 particles in total HDL pool.
