The effect of saponin isolated from stems and leaves of ginseng (SLG) on immunologic function in mice / 中国病理生理杂志

ABSTRACT

The effects of SLG on the immune function of normal and immune-suppressed mice were investigated. The results showed that SLG (50mg/kg, im) could correct the suppressive effect of cyclophosphamide, dexamethasone or prednisolone on spleen and. thymus weight, serum specific antibody level and lymphocyte transformation. SLG could also improve the phagocytic activity of peritoneal macrophages and enhance peripheral blood ANAE+-lymphocyte ratio of mice. No obvious effect of SLG on the normal mice were observed except that it could increase the antibody level of normal mice. The results implicate that SLG may have some immunomodulatory effect.
