Abstract:

The purpose of this study was to assess the synergistic effect of polydatin and vitamin C on attenuating cardiotoxicity induced by doxorubicin (DOX) in rats. Polydatin could significantly increase the activity of SOD and the heart rate, attenuate myocardial pathological damage, decrease MDA content, slightly increase arterial pressure and GSH-Px activity, reduce intervals of QRS, QT and ST, and lower FFA content. The combination of polydatin and vitamin C could significantly increase arterial pressure and heart rate, decrease QRS interval and slightly reduce ST and QT intervals, significantly attenuate myocardial pathological damage, increase the activities of GSH-Px,T-SOD, Na(+) K(+) -ATPase and Ca(2+) Mg(2+) -ATPase, and elevate PCr and ATP contents, slightly increase ADP and TAN contents and PCr/ATP, and significantly decrease the contents of MDA and FFA, when compared with those in the DOX group. Meanwhile, the improvement effects on FFA content, the activities of ATPase and SOD and contents of ATP and TAN in combination group were more obvious than those in polydatin group; and the improvement effects on arterial pressure, heart rate, interval of QRS, GSH-Px activity, and MDA, ADP and PCr contents in combination group were slightly obvious when compared with those in polydatin group. In addition, the mRNA expression levels of AMPK-α2 and PPAR-α were slightly improved in combination group. The results illustrate that the combination of polydatin and vitamin C has the ability to enhance the myocardial protective effects by its antioxidative effect and improving energy metabolism.
