The therapeutic effects of 3′-daidzein sulfonate sodium on isolated myocardial ischemia/reperfusion injury and its relation with anti-oxidation / 中国药理学通报

ABSTRACT

Aim To explore the therapeutic effects of 3′-daidzein sulfonate sodium(DSS) on isolated myocardial ischemia/reperfusion injury and the relation of its mechanism to anti-oxidation.Methods An isolated rat myocardial ischemia/reperfusion injury was made,and the injury was treated with DSS.Following the treatment,the coronary blood flow levels,left ventricular systolic pressure,and activities of enzymes(LDH,SOD,GSH-Px) were measured.Results After treatment,the isolated myocardial tissue showed an increase in the volume of perfusion and an increase in the enzymatic activities of LDH,SOD,GSH-Px in the myocardial tissue.Conclusion DSS has a therapeutic effect on isolated myocardial ischemia/reperfusion injury because it enhances anti-oxidative activity in myocardial tissue.
