Except the control group,the rest groups of mice were injected with Cytoxan at60 mg/kg to reproduce the immunosuppressive mice model,and were fed through stomach at 0. 5g/kg,1. 0 g/kg and 2. 0 g/kg Nuhuang Fuzheng Granules for seven days( twice a day); the positive control group was fed with Astragalus Polysacharin( 500 mg/L). The carbon clearance index,immune organ index,serum hemolysin were determined. IL-2,IFN-γ,and IL-4 levels in mouse serum were measured by ELISA. [Results] Nuhuang Fuzheng Granules could significantly incease the carbon granular expurgation index of mice with Cytoxan-induced immunosuppression,and the 2. 0 g/kg and 1. 0 g/kg dosage groups had better effect than 0. 5 g/kg dosage group( P < 0. 05); the spleen index of mice with Cytoxan-induced immunosuppression increased significantly and there was dose-effect relationship in a certain range of concentration; the thymus index and serum hemolysin HC_(50) were significantly higher than 0. 5 g/kg dosage group( P < 0. 05); IL-4 and IFN-γ in the serum was significantly higher than the model group( P < 0. 01),the increase of IL-2 was not significantly( P > 0. 05). [Conclusions] Nuhuang Fuzheng Granules can promote growth of immune organs and secretion of cytokines through improving the carbon granular expurgation ability of mice with Cytoxan-induced immunosuppression.展开更多
