Antiatherosclerotic potency of high density lipoprotein of different origins: a review and some new findings

Abstract The antiatherosclerotic potency of isolated high density lipoproteins (HDL) of different origins was investigated in three experimental models: (1) isolated HDL were injected into cholesterol-rich fed rabbits; (2) the effect of HDL on the intracellular level of free and esterified cholesterol as well as on proliferation of smooth muscle cells and fibroblasts was investigated in cell cultures; and (3) we studied the influence of isolated HDL fractions on thromboxane (TXB 2 ) formation in clotting whole blood with different cholesterol content.
