Abstract:
Objective:To explore the effect of gingko flavonoids on the content of SOD and MDA and cardiac function in the rats with heart failure. Methods:Totally 40 male Sprague-Dawley rats were randomly divided into 5 groups by random number table meth-od, namely the blank group, the model group, low-dose gingko flavonoids group, high-dose gingko flavonoids group and metoprolol group. Except the blank group, all the other groups were subcutaneously injected 300 mg·kg-1 isopropyl adrenaline for two days to make the heart failure model. After that, metoprolol group was given metoprolol 20 mg·kg-1 ·d-1 , the ginkgo flavonoids group was given 250 or 500 mg·kg-1 ·d-1 ginkgo flavonoids extract, the other groups were given physiological saline with the same volume, and the treatment course was 8 weeks. After the treatment, cardiac function indices ( IVST, LVPWT, LVEDD, LVESD and LVEF) , SOD and MDA levels in cardiac muscle tissue and the pathological integral, and myocardial pathologic morphology characteristics were deter-mined. Results:LVEDD and LVESD of the two ginkgo flavonoids groups and metoprolol group were obviously improved compared with those of the model group, while LVEF, IVST and LVPWT were significantly decreased (P<0. 05), showing that the cardiac function was improved after the treatment. The levels of SOD were raised, while MDA and the pathological integral were decreased significantly in the two ginkgo flavonoids groups compared with those of the model group (P<0. 05), with a dose-dependant relationship. Conclu-sion:Ginkgo flavonoids have certain protective effect in heart failure rats, and the mechanism may be related to reducing the level of lipid peroxidation and improving the body antioxidant enzyme activity.
