Abstract:
To evaluate the possibility that the ginseng saponins could be developed as an anti-arteriosclerotic agent, we examined the inhibitory effects of ginseng saponins (total saponin(TS), panaxatriol(PT), panaxadiol(PD)) on the expression of c-fos mRNA and the proliferation of cultured rat aortic vascular smooth muscle cells (VSMCs) stimulated by angiotensin II (Ang II). TS and PT (1.0 mg/ml) suppressed c-fos mRNA induction in VSMCs stimulated by 10-5 M Ang II. The order of inhibitory potency was PT>TS. Ginseng saponins (0.01~1.0 mg/ml) inhibited the proliferation of VSMCs stimulated by Ang II in a concentration dependent manner, the inhibitory potency was TS> PT> PD at 0.1~1.0 mg/ml. These results suggest that ginseng saponins may suppress Ang II-stimulated proliferation of aortic VSMCs which can be seen in atherosclerosis, hypertension and restenosis.
