Objective:To observe the effects of Jinhuang Fuzheng tea on spleen T

B lymphocyte proliferation and peritoneal macrophage immune function in the Immunosuppressed mice.Method: Mice were ig administrated Jinhuang fuzheng tea at high

middle and low dose for 10 days.The immunosuppression mouse model was caused by subcutaneous injection of cyclophosphamide（30 mg·kg-1） every other day.The determination of concanavalin A（Con A） induced T lymphocyte proliferation and lipopolysaccharide（LPS） induced B lymphocyte proliferation and natural killer cells（NK cells） and lymphokine-activated killer cells（LAK cells） activity was examined by tetrazolium blue（MTT）.The inducible nitric oxide synthase（iNOS） secreted by peritoneal macrophages activity was measured by enzymic method.Automatic detection microplate reader was used to determine the capability of phagocytosis neutral red.Result: The immunosuppressed mice which were given Jinhuang Fuzheng tea at low

medium and high dose groups showed a increased T and B lymphocyte A value（P<0.01）;The medium and high dose groups significantly improved NK cells LAK cell activity

phagocytic activity of peritoneal macrophages and iNOS activity in immunosuppressive mice（P<0.01

P<0.05）.Conclusion: The Jinhuang Fuzheng tea can promote the immune function in Immunosuppressed mice.
