Abstract:
Aim To study the effect of pectin-adriamy-cin conjugate ( PAC) on cardiac toxicity .Methods 50 female SD rats were randomly divided into 5 groups with 10 animals in each group .Adriamycin ( ADM ) group received 3 mg? kg -1 , ip, every other day for 6 times.PAC group received ADM equivalent 1.5,3 and 6 mg? kg -1 , ip, every other day for 6 times.Control group received normal saline parallel to ADM .Rats were sacrificed and the echocardiogram , cardiac en-zymes , the oxidative stress levels in myocardial cells and histopathological changes after 48 h administration were detected.S180 ascites tumor bearing mice models were established to investigate the antitumor activity of PAC.Results The survival rate of ADM group was 50% and that of PAC each group was 100%.PAC could significantly increase body weight ,heart index and immune index and increase HR ,EF,FS,reduce LVIDd, LVIDs.PAC could also significantly increase the AST , LDH, CK, CK-MB level in serum .GSH-Px and SOD activities of PAC group were significantly increased and MDA contents were reduced , and histopathological changes decreased .PAC could effectively inhibit the growth of tumor cells and extend the survival period of mice.Conclusion PAC induces a significant reduc-tion in cardiotoxicity by increasing survival rate , im-mune and cardiac function , improving cardiac en-zymes ,oxidative stress and myocardial cell injury , and also PAC has obvious antitumor effect .
