ABSTRACT
Aim To investigate the effect of L-arginine(L-Arg) on myocardium in rat which suffered from limb ischemia-reperfusion.Methods Models of limb ischemia reperfusion were made by tourniquet methods.L-Arg(150 mg?kg-1) were intravascularly injected before reperfusion.Contents of malondialdehyde(MDA),myeloperoxidase(MPO) and tumour necrosis factor(TNF-?) in myocardium were measured.Levels of creatine kinase(CK),creatine kinase MB isoenzyme(CK-MB) and nitric oxide(NO) in plasma were deter-mined.The mean arterial pressure(MAP,left venteicular systolic pressure(LVSP),maximal rise rate of left venteicular pressure(dp/dtmax)and the maximal fall rate of left venteicular pressure(-dp/dtmax)were monitored.Morphologic changes of myocardium were evaluated after reperfusion.Results After rats' limbs suffering from ischemia-reperfusion,levels of MDA,MPO and TNF-? in myocardium,CK,CK-MB and NO in plasma increased differently(P
