律白纯系小鼠隔日背部皮下注射1.5％浓度的黄芪皂苷甲0.1ml/次,共2周,经淋巴结组织学研究表明:(1)黄芪皂苷甲能明显促进B细胞增殖分化和浆细胞抗体合成,但对T细胞未见明显影响;(2)给药后,巨噬细胞超微结构和吞噬功能有不同程度的改变和增强。实验结果提示黄芪皂苷甲可能为黄芪在免疫促进作用方面的重要有效成份之一。 Pure white mice were subcutaneously injected with 1.5% astragaloside A at a dose of 0.1 ml every other day for 2 weeks. Histological studies of lymph nodes showed that: (1) Astragaloside A can significantly promote B cell proliferation and plasma cell antibody Synthesis, but no obvious effect on T cells; (2) After the administration, macrophage ultrastructure and phagocytic function have changed and enhanced to varying degrees. The experimental results suggest that Astragaloside A may be one of the important active ingredients of Astragalus membranaceus in immune promotion.
