| 中文摘要: |
| 本文研究了螺旋藻中的硒多糖 (selenium polysaccharide,Se PS)抑制肿瘤细胞和对小鼠免疫功能的影响。发现硒多糖对肿瘤细胞的抑制率均大于相同剂量的多糖 (PS)。高浓度的 Se PS和 PS(10 0 mg· kg-1)处理能显著提高小鼠的脾指数 ;PS和 Se PS都能显著提高 CY处理后的胸腺指数和脾指数 ;剂量 5 0 mg· kg-1以上的 Se PS或 PS与 Con A协同作用能显著刺激小鼠淋巴细胞增殖 ;Se PS两个剂量 (5 0 mg· kg-1和 10 0mg· kg-1) NK细胞对靶细胞的杀伤率分别达到 33.2 %和 4 0 .8% ,与对照组 (19.0 % )相比 ,达到极显著差异 ,PS(5 0 mg· kg-1)达到显著差异 (2 9.9% ) ,PS(10 0 mg· kg-1)达到极显著差异 (38.0 % ) |
| English Summary: |
| Polysaccharide is used for adjuvant immunotherapy of malignant diseases.We studied the potential applicability of Selenium polysaccharide (SePS) from Spirulina platensis for improving immune function using an experimental model of murine lymphoma,compared with polysaccharide (PS) in Spirulina platensis. SePS and PS have no effect on thymus index;spleen cell proliferation was heightened by high concentrations of SePS and PS;synergism of SePS,PS with ConA is significant.SePS treatment enhance the ability of natural killer cell in mice spleen to kill target cell of YAC 1;conclusively,SePS treatment is more significant in the improvement of immuofunction than that of PS. |
