The effects of liqustrazin on cardiac hemodynamics,oxygen free radicals and lipid peroxide in serum and in myocardium during myocardial ischemia reperfusion injury in rabbits were observed.The group protected with liqustrazin,as compared to the nonprotected group, showed that LVSP, LV+dp/dtmax and LV dp/dtmax increased significantly (P<0 05 or P<0 01),simultaneously,in serum MDA content decreased remarkablely (P<0 05) and GSH PX/LPO rate increased very significantly (P<0 01) and in postischemia reper...
