ABSTRACT
[Objective] To observe effects of HQSM on CK, LDH and AST activity in serum of acute myocardial ischemia rats caused by injecting pituitrin.[Method] SD rats were divided into several groups at random: normal control group,model control group, three HQSM groups(210mg/kg,150mg/kg,105mg/kg), positive control group(Huangqi Shengmaiyin and Diao Xinxuekang).The rats were treated with respective drugs by ig for 30 days, and pituitrin was injected respectively by caudal vein 1h after administering at the 29th and 30th days.Blood serum was taken out to determinate the activity of CK, LDH and AST at 1h and 24h after the last injection. [Result] The activity of LDH and AST in serum increased at 1h after injecting pituitrin, the activity of CK in serum increased,meanwhile LDH and AST was still higher than normal control group at 24h. HQSM could decrease the activity of CK and AST(P
