目的研究红景天多糖对体外正常人T淋巴细胞活性和对体外人胃癌细胞增殖的影响。方法采用MTT比色法和体外细胞培养计数法。结果红景天多糖对体外PHA诱导的正常人外周血T淋巴细胞的增殖有显著性促进作用(P<0.05);红景天多糖对体外人胃癌细胞增殖有显著性抑制作用(P<0.05),且红景天多糖作用强于香菇多糖(P<0.05)。结论红景天多糖可能是一种免疫增强剂,对胃癌可能有一定防治作用。
Objective To study the effects of rhodiola polysaccharides on the activity of T lymphocytes in vitro and the proliferation of human gastric cancer cells in vitro. Methods MTT colorimetric method and in vitro cell culture counting method. Results Rhodiola rosea polysaccharide on PHA-induced normal human peripheral blood T lymphocyte proliferation was significantly improved (P <0.05); Rhodiola polysaccharides on human gastric cancer cell proliferation was significantly inhibited (P <0.05) , And Rhodiola rosea polysaccharide was stronger than lentinan (P <0.05). Conclusion Rhodiola polysaccharide may be an immune enhancer, gastric cancer may have some control effect.
