海带多糖对小鼠T淋巴细胞及NK细胞活性的影响

将80只昆明小鼠随机分为8组,4组为正常小鼠,4组为环磷酰胺至免疫抑制小鼠.分别以250,500,1 000 μg/g的海带多糖灌胃正常小鼠和免疫抑制小鼠,以灌胃蒸馏水小鼠为对照,采用MTT法测定T淋巴细胞增殖能力,乳酸脱氢酶法测定NK细胞活性.结果表明,500和1 000 μg/g的海带多糖能够显著增强正常小鼠和免疫抑制小鼠的T淋巴细胞增殖能力,并能提高NK细胞活性.

Influence of Laminarina Japonica Polysaccharides on T-lymphocyte and NK Cell Activity in Mice

To observe the influence of laminarina japonica polysaccharides(LJP)on T-lymphocyte and NK cell activity in mice,the kunming mice were fed with LJP at doses of 250,500,1 000 μg/g.By using MTT method and LDH test,the effect of LJP on proliferating capability of T-lymphocyte and NK cell activity were evaluated in normal mice and immunosuppressive mice.The result showed that LJP 500,1 000 μg/g enhanced proliferating capability of T-lymphocyte and NK cell activity in normal mice and immunosuppressive mice.
