Abstract

|
The oxidative modification of low density lipoprotein(LDL) has been implicated in the development of atherosclerosis. Oxidized LDL are found in macrophage foam cell, and it can induce an macrophage proliferation in atherosclerotic plaque. In this study, we investigated the hypothesis that gamisoyosan(GS) may reduce atherosclerosis by lowering the oxidiazability of LDL, To achive this goal, we examined the effect of GS on LDL oxidation, nitric oxide production in mouse macrophage cell line, RAW264.7, and the effect of GS on cupuric sulfate-induced cytotoxicity, LDH release, and macrophage activity. GS inhibited the generation of oxidized LDL from native LDL in RAW264.7 cell culture, and decreased the release of LDH from cupric sulfate-stimulated RAW264.7 cell. In other experiments, GS activated RAW264.7 cell, and prolonged the survival time, and increased nitric oxide production in Raw 264.7 cells.
