研究了二色桌片参多糖－１（ＰＭＩ－１）在体内、体外的免疫调节作用．结果表明，二色桌片参多糖－１体外能促进小鼠脾淋巴细胞增殖，促进小鼠脾淋巴细胞分泌ＩＬ－２；体内能显著促进迟发型超敏反应，增加脾指数、胸腺指数；具有显著的免疫增强作用。The immunoactivities of PMI-1 are studied in vivo and in vitro. PMI-1(5. 50. 100u g/mL ) in vitro could promote the proliferation of mice lymphocyte, and increase IL-2 production as well. In vivo, PMI-1 could significantly improve the delayed-type hypersensitivity (DTH) degree and the weights of spleen and thymus, although it has little effect on the production of hemolysin antibodies. The results indicate that PMI-1 could remarkedly enhance the immunofunction in mice
