ABSTRACT
Objective To investigate the protective effect of gross saponin tribulus terrestris(GSTT) on the apoptosis of pheochromocytoma cells(PC12 cells)induced by H2O2 and its mechanisms.Methods PC12 cells were divided into control,model,high dose GSTT(GSTT1) and low dose GSTT(GSTT2) groups.Apoptosis of PC12 cells was induced by H2O2 at the concentration of 300? mmol?L-1.The cell activity was determined by MTT.The subdiploid peaks showing cell apoptosis rate and ?m were detected by flow cytometry.Proteins of Bcl-2 and Bax were detected by immunohistochemistry.Results Compared with model group,the survival rate of PC12 increased(P

ABSTRACT
Aim To investige the protective effect of FMCL on the apoptosis of PC12 cells induced by H_2O_2 and its mechanisms.Methods Apoptosis of PC12 cells induced by H_2O_2 at the concentration of 0.5 mmol?L~(-1).The cell activity was determined by MTT.The morpholog changes were observed by invert microscope.DNA ladder was observed through agarose gel electrophoresis.The subdiploid peaks showing cell apoptosis rate and △?m were detected by flow cytometry.Results Compared with those of the Model group the cell activity of FMCL 100、30 mg?L~(-1) group reinforced,the injury of the cell relieved.The apoptosis rate of those two groups decreased,but the△?m and the cell activity increased in a dose-dependent manner.Conclusion FMCL can inhibit the apoptosis of PC12 induced by H_2O_2 which might be correlated with the increasion of △?m.
