摘　　要：目的:研究当归多糖对小鼠免疫功能的影响.方法:ig氢化可的松复制免疫抑制模型;测定胸腺、脾脏重量并计算脏器系数;碳粒廓清法测定单核巨噬细胞吞噬功能;测定血清溶血素IgG、IgM含量;MTT法测定细胞增殖.结果:在10～100mg·kg-1剂量范围内,当归多糖能对抗氢化可的松引起的小鼠脾萎缩,而对胸腺影响不大;显著增加氢化可的松免疫抑制小鼠的碳粒廓清率;而对小鼠血清溶血素IgG、IgM的生成有较强的抑制作用;当归多糖还能显著增强小鼠脾细胞和腹腔巨噬细胞的增殖.结论:当归多糖能增强非特异性免疫功能,而对体液免疫功能有抑制作用.AIM: To investigate the immunoloregulation effect of Angelica polysaccharide extracted from Angelica Sinensis (Oliv.) Diels. METHODS: Index of immune organs were weighed and calculated. Phagocytosis of mononuclear macrophage (M) were determined with carbon particle clearance test. Spectrophotography was used to estimate levels of serum hemolysis IgG, IgM. The cell proliferation was measured by MTT assay. RESULTS: In certain doses (10-100 mg/kg), Angelica polysaccharide significantly increased phagocytic function and spleen index in immunosuppression mice caused by hydrocortisone, while showed no obviouse influnence on thymus index. It also remarkble decreased levels of serum hemolysis IgG, IgM. In vitro experiments, Angelica polysaccharide could increase the proliferation of mouse spleen cell and macrophage. CONCLUSION: These results suggest that Angelica polysaccharide has potent enhancement on non specific immunity, however, it could suppress humoral immunity.
