摘要
Objective:To probe into the intervening action of polysaccharides of Zhu Zi Shen(Rhizoma Panacis Majoris)(PZZS) on oxidative stress and hemodynamics in rats with adriamycin-induced chronic congestive heart failure(CHF).Methods:After SD rats were successfully modeled with adriamycin,they were randomly divided into a normal control group,a model group,a PZZS group,and a captopril group,and were administrated respectively.At the end of experiment,the hemodynamic function,whole heart weight index,and the blood CK,SOD,MDA,NO,NOS were detected;and the myocardial morphological examinations were carried out.Results:Compared with the normal control group,the arterial systolic pressure(SBP),diastolic pressure(DBP),mean arterial pressure(MAP),heart rate(HR),left ventricular systolic peak(LVSP),and left ventricular pressure change rate(dp/dtmax) significantly decreased,and left ventricular end diastolic pressure(LVEDP),whole heart weight index,the blood CK,MDA,NO,NOS significantly increased in the model group.PZZS significantly improved the hemodynamic function,lowered the MDA and NO levels,and decreased the CK and NOS activities in the CHF rats.Conclusion:PZZS can improve the hemodynamic function,and alleviate the oxidative stress reaction in the CHF rat.
