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.
