| Abstract: | Objective] To discuss the protection and regulatory effects of Yupingfeng polysaccharides on immunosuppressed mice. Methods] The immunosuppressive mice model was established by 80 mg / kg cyclophosphamide. The spleen index,spleen lymphocyte proliferation capability,serum hemolysin antibody generation and serum IL-2 level of mice were researched,so as to observe the effects of Yupingfeng polysaccharides at different dosages( 100,200,400 mg / kg). Results] Yupingfeng polysaccharides enhanced the spleen index of immunosuppressed mice,improved the proliferation capability of spleen lymphocyte,promoted the generation of serum hemolysin antibody in normal mice,and protected against the secretion reduction of serum hemolysin antibody induced by cyclophosphamide. Besides,Yupingfeng polysaccharides enhanced the IL-2 levels in serum of both immunosuppressed and normal mice,especially that the middle-and low-dosage groups had relatively significant effects.Conclusions] Yupingfeng polysaccharides protected against the immunosuppression of mice induced by cyclophosphamide,enhanced the immune function and protected the spleen function of mice. |
