目的:探讨芦荟多糖对老龄大鼠免疫功能的影响。方法:以老龄大鼠为模型,观察不同剂量(5g/kg、10g/kg、20g/kg,体重)芦荟多糖对老龄大鼠免疫器官指数、巨噬细胞吞噬率和吞噬指数、脾淋巴细胞增值能力的影响。结果:不同剂量芦荟多糖对胸腺及脾脏指数无明显影响,但能明显促进老龄大鼠脾淋巴细胞增值转化,大中剂量并能提高巨噬细胞的吞噬率和吞噬指数。结论:芦荟多糖具有增强和促进老龄大鼠免疫功能的作用。
Objective: To investigate the effect of aloe polysaccharide on immune function in aged rats. METHODS: Older rats were used as models to observe the effects of different doses (5, 10, 20, and 20 mg/kg body weight) of aloe polysaccharides on immune organ index, macrophage phagocytosis and phagocytic index, and spleen lymphocyte proliferation in aged rats. The impact of capacity. Results: Different doses of Aloe polysaccharides had no significant effect on thymus and spleen index, but it could significantly promote the increase of spleen lymphocyte proliferation in aged rats. Large and medium doses could increase the phagocytosis rate and phagocytic index of macrophages. Conclusion: Aloe polysaccharide can enhance and promote the immune function of aged rats.
