title: [HDL2 and HDL3 cholesterol in men and women in different forms of hyperlipidemia without arterial involvement].
abstract: The investigation was carried out in one hand on 54 hyperlipidemic men without arterial injury compared to 54 normolipidemic men, on the other hand on 50 hyperlipidemic women compared to 50 normolipidemic women. The hyperlipidemic subjects were separated in IIa, IIb and IV groups, according to WHO classification. Lipoprotein's separation was carried out by sequently ultracentrifugation and HDL2-HDL3 were isolated at a solvant density of 1.125 and 1.21; cholesterol was measured by enzymatic method. We observed a significant decrease of: (Formula: see text) ratio in all hyperlipidemic subjects compared to controls; but no significant variation of HDL2 and HDL3 cholesterol appeared in the three groups of hyperlipidemic subjects compared to controls; on the other hand we noted a HDL2 cholesterol greater in women than in men and this fact seems to prove a favorable action of this fraction in preventing atherosclerosis. The (Formula: see text) ratio remains the most discriminant factor of hyperlipidemia, but the: (formula: see text) ratio seems interesting and HDL2 cholesterol is always higher in women during hyperlipidemia with high risk, IIa and IIb.
