[Effect of prim-o-glucosylcimifugin and 4'-O-beta-D-glucosyl-5-O-methylvisamminol con on proliferation of smooth muscle cell stimulated by TNF-alpha].
OBJECTIVE
To investigate the effect of prim-O-glucosylcimifugin and 4'-O-p-D-glucosyl-5-O-methylvisa-mminol con on the proliferation of smooth muscle cell stimulated by TNF-alpha.


METHODS
The primary cell culture method of smooth muscle cell (SMC) was established by attachment-block. The SMC was identificated by immunochemistry method, and the growth curve was drawn by cytometry. The third generation of SMC was adopted in the experiment. The effect of prim-O-glucosylcimif-ugin and 4'-O-beta-D-glucosyl-5-O-methylvisamminol con on the proliferation and cell cycle of SMC was investigated by MTT and flow cytometry respectively.


RESULTS
TNF-alpha of 5 micro g x L(-1) can stimulate the proliferation of SMC and increase the proportion of G2 phase and S phase in cell cycle which has great significant difference (P < 0.01) compared with control. The three dose groups of prim-O-glucosylcimifugin and 4'-O-beta-D-glucosyl-5-O-methylvisammin-ol con can inhibit the proliferation of SMC and increase the proportion of G0/G1 phase, which has great significant difference (P < 0.01) compared with model group.


CONCLUSIONS
Prim-O-glucosylcimifugin and 4'-O-beta-D-glucosyl-5-O-methylvisamminol con can inhibit the proliferation of SMC stimulated by TNF-alpha.
