牛大力多糖对免疫抑制小鼠的免疫调节作用

目的探讨牛大力多糖对免疫功能低下小鼠的免疫调节作用。方法采用环磷酰胺和荷瘤的方法建立免疫抑制小鼠动物模型,小鼠以灌胃的方法给予不同剂量牛大力多糖,利用MTT检测淋巴细胞转化及巨噬细胞吞噬中性红实验,分析牛大力多糖对免疫抑制小鼠的影响。结果牛大力多糖可增强吞噬细胞的吞噬功能,增加抗体形成细胞的数量,促进淋巴细胞转化。结论牛大力多糖明显具有增强小鼠免疫功能的作用,以高剂量组效果最为显著。

Immunoregulatory Effects of Polysaccharide on Immunosuppressed Mice

Objective To investigate immunoregulatory activity of polysaccharide of Niudali (NDLS) on immunosuppressed mice.Methods The models of immunosuppressed mice were established by treating with cyclophosphamide and tumor-bearing. Different doses of NDLS were orally administered to the mice. MTT method was used to observe the proliferation of lymphocytes and the function of macrophages in abdominal activity was also measured. Spectrophotometry was adopted to evaluate the ability of plaque forming cells.Results N...
