ABSTRACT
Acute myocardial ischemia and reperfusion led to arrhythmias and increase of glutamic oxalacetic transaminase (GOT),lactate dehydrogenase (LDH),non-csterified fatty acid (FFA) and malondialdehyde (MDA) content, and decrease of superoxide dismutase (SOD) activity in rats. 3, 6-di-methylamino-dibenzopyri-odonium edetate (IHC-72) 5 mg?kg-1 iv significantly reduced the incidence of ventricular tachy-cardia (VT) and ventricular fibrillation(VF) ,shortened the duration of arrhythmias induced by reperfusion, decreased the release of GOT, LDH and FFA, obviously reduced the MDA content,and effectively protected SOD activity in ischemia-reperfused rat hearts. Our experimental results suggested that IHC-72 had protective effects on ischemia-reperfusion injury rat hearts in vivo. The mechanism of the protection might be associated with the inhibition of cellular lipid peroxidation.
