Effect of Schizandrae Lignanoid on PC12 cell apoptosis induced by H_2O_2 / 吉林大学学报(医学版)

ABSTRACT

Objective To investigate the protective effect of Schizandrae Lignanoid(SCL)on the apoptosis of PC12 cells induced by H2O2 and its relative mechanisms.Methods PC12 cells were divided into four groups control group,model group,high dose SCL(SCL1) group,and low dose SCL(SCL2) group.Apoptosis of PC12 cells was induced by H2O2.The cell activity was determined by MTT,the cell apoptotic rate was determined by Annexin V-FITC/PI and ??m was detected by flow cytometry.The expressions of bcl-2 and bax were detected by immunohistochemistry.Results Compared with model group,SCL increased the survival rate of PC12 cells(P
