摘要
本文对我院合成的苄普地尔的抗心肌缺血作用作了实验研究。在家兔结扎左冠状动脉的前降支造成急性心肌梗塞中,Bep5mg·kg^(-1)和Pro1mg·kg^(-1)均能使ECG的∑ST,NST,NQ降低,与NS组比较P<0.01,ST段恢复至等电位线的时间提前.梗塞心肌占全心重量的百分比减少,CPK测定值比NS组降低。Iso诱发大白鼠心肌缺血的实验中.Bep5,10mg·kg^(-1)与Pro5mg·kg^(-1)均可使∑ST↑↓的总mV数减少,与NS组比较P<0.01,病理组织学检查心肌损伤亦减轻。
Bepridil hydrochloride
(Bep) hydrochloride is a new , long - acting antianginal and antiarrhythmic agent. Through the observation of ∑ST.NST.and NQ of ECG or nitro blue tetrazolium chloride staining, we studied the effect of Bep on liga-tion of the left coronary artery in rabbits and the myocardial ischemia induced by isopre-naline in rats. The results showed that in the groups treated with Hep andpropranolol the
isoelectric level was facilitated. ∑ST.NST, NQ, thecreatine phosphokinase values and the weight percentage of infarcted myocardium were decreased. The myocardial ischemic injury was decreased by histopathological stud-
