Abstract:
AIM To observe the protective effect of total flavone of Abelmoschl Manihot L medic(TFA) on myocardial ischemia reperfusion injury(IRI) in the rat heart in vitro. METHODS We adopted the method of in vivo perfusion set up by Langendorff to observe the changes of some markers, such as MDA,SOD,CPK,LDH,etc in the myocardial homogenate in the rat heart following ischemia and reperfusion. RESULTS TFA( 100,50,25 mg?L -1) can significantly reduce the lipid peroxidation product malondialdehyde(MDA), increase the activity of myocardium superoxide dismutase(SOD), decrease the transudation of creatine phosphokinase(CPK) and lactate dehydrogenase (LDH) from cardiomyocyte. And also, TFA caused an improvement of nitric oxide (NO) and its synthase, NOS. CONCLUSION TFA play a protective role on myocardial reperfusion injury in the rat in vitro via inhibition of lipid peroxidation, enhancement of anti-oxidation and relaxing of coronary artery.
