title: [Atherogenic oxidative and structural modification of low density lipoproteins in men with coronary atherosclerosis].
abstract: We studied parameters of structural and oxidative modification of low density lipoproteins (LDL) in 80 men aged 35 - 65 years with coronary atherosclerosis verified at coronary angiography in comparison with 80 men of the same age without ischemic heart disease. Biochemical studies included determination of parameters of lipid blood composition by enzymatic methods, subfractional LDL profile by electrophoresis in 2 - 16% gradient polyacrylamide gel, degree of oxidative modification of lipid (lipid peroxidation products) and apoprotein (carbonyl groups) components of LDL by fluorometric and spectrophotometric methods. In men with coronary atherosclerosis we revealed elevated level of small dense LDL and substantially oxidized lipid and apoprotein components of these particles. Independent association of structural and oxidative modification was shown.
