    Abstract:
    As the alpha-cholesterol concentration decreased in blood plasma of healthy men, relative content of oleic and linoleic acids was also decreased in phospholipids of HDL2 subfraction without any alterations in HDL3 fraction. In the patients with ischemic heart disease content of linoleic acid was lower in the phospholipids and the ratio free cholesterol (HDL2 phospholipids was higher as compared with the group of healthy persons exhibiting the similar low content of cholesterol in HDL. The molar ratio free cholesterol) phospholipids was higher in the HDL3 fraction of the patients as compared with healthy persons, however composition of fatty acids was unaltered in the phospholipids Activity of lecithine cholesterol acyltransferase was lower in the patients as compared with healthy persons exhibiting the same content of cholesterol in HDL. Administration of heparin into the patients was responsible for an increase in the level of unsaturated phospholipids in HDL2 fraction (while they decreased in VLDL/as well as for a decrease in the ratio cholesterol/phospholipids. The data obtained suggest that alterations in the physico-chemical properties of the fraction studied might affect the antiatherogenic characteristics of HDL.
