| Popis: | To explore the effects of plasma containing Buyang Huanwu Decoction (BYHWD), a compound of traditional Chinese medicine, and its effective components (alkaloids and glycosides) and total Panax notoginseng saponins (TSPN) on vascular smooth muscle cell (VSMC) proliferation induced by platelet-derived growth factor (PDGF) in vitro.VSMC proliferation was induced by incubating VSMCs with PDGF-BB. Effects of different concentrations of blank plasma on the VSMC proliferation and 50% inhibitory concentrations of plasma containing BYHWD, its alkaloids and glycosides, TSPN and atorvastatin were detected by using methyl thiazolyl tetrazolium (MTT) method to determine the concentrations of plasma containing drugs for the following experiments. Then, MTT and flow cytometry methods were used to detect the effects of plasma containing BYHWD, its alkaloids and glycosides, TSPN and atorvastatin on VSMC proliferative activity and cell cycles.VSMC proliferative activity was enhanced obviously after PDGF-BB stimulation. The cell number in G(0)/G(1) phase was decreased and the cell quantity in G(2)/M and S phases was increased following PDGF-BB stimulation. Compared with PDGF-BB stimulation group, VSMC proliferation induced by PDGF-BB in plasma containing BYHWD, its alkaloids and glycosides, TSPN and atorvastatin groups was inhibited. In all plasma containing drug components groups, the cell number of G(0)/G(1) phase was higher and the cell quantity of G(2)/M and S phases was lower than those in the PDGF-BB stimulation group.BYHWD and its alkaloids and glycosides have similar roles of resisting VSMC proliferation to TSPN and atorvastatin. Alkaloids and glycosides may be the major effective substances of anti-VSMC proliferation in BYHWD. |
