Impaired Antiatherogenic Function of High-Density Lipoproteins in the Presence of Various Risk Factors for Coronary Heart Disease

Abstract

We studied acception of cholesterol from Fu5AH hepatoma cells by blood serum from subjects with normal level of high-density lipoprotein cholesterol and hyperlipidemia (alone or in combination with other risk factors for coronary heart disease). Cholesterol-binding activity of high-density lipoproteins decreased in subjects with hyperlipidemia alone or in combination with excess body weight and/or arterial hypertension. Impairment of high-density lipoprotein activity was associated with changes in their phospholipid composition.

Association of serum apolipoprotein A-II concentration with combined hyperlipidemia and impaired glucose tolerance

“…Individual PL were separated by thin-layer chromatography [2]. CH-acceptor activity of serum HDL was estimated by the release of 3 H-CH from rat hepatoma Fu5H cells [2]. Oral glucose tolerance test was performed to reveal disturbances in carbohydrate metabolism.…”
