Effect of Chuanmingshen violaceum polysaccharides and its sulfated derivatives on immunosuppression induced by cyclophosphamide in mice / 中国免疫学杂志

ABSTRACT

Objective:In oder to investigate the effect of Chuanmingshen violaceum polysaccharides ( CVP) and Solfated Chua-nmingshen violaceum polysaccharides ( SCVP) on immunosuppression induced by cyclophosphamide ( CY) in mice.Methods: CY were used to induce immunosuppression in mice;Spleen and thymus indexes were used to evaluate the immune organs indexes;the [3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltet-razolium bromide,MTT] method was used to detect the proliferation of spleen lymphocytes of each group;the concentrations of IFN-γand IL-2 were assayed by ELISA kit.Results: SCVP and CVP could resist immunosuppression by promoting lymphocyte proliferation, increasing the contents of IFN-γ and IL-2, promoting immune organs development in immunosuppressive mice induced by CY.Conclusion:SCVP and CVP exhibited the potential to used as immunopotentiator.
