Immunoloregulation effect of Angelica polysaccharide isolated from Angelica sinensis / 中国药理学通报

ABSTRACT

AIM To investigate the immunolore gulation effect of Angelica polysaccharide purified from Angelica sinensis(Oliv.)Diels. METHODS Index of immune organs was weighed and caculated. Phagocytosis of mononuclear macrophage (M?) was determined with carbon particle clearance test. Spectrophotography was used to estimate levels of serum hemolysis IgG, IgM. Mixed lymphocyte reaction was measured by MTT assay. RESULTS In certain concentrations (10～100 mg?kg -1 ), Angelica polysaccharide significantly in creased phagocytic function and spleen index inboth normal and immunosuppression mice,caused by sc cyclophosphamide, but showed no obviouse influnence on thymus index. It also remarkbly decreased levels of serum hemolysis IgG, IgM. CONCLUSION These results suggest that Angelica polysaccharide has potent enhancement on non specific immunity. However, it could suppress humoral immunity.
