摘要: 目的: 研究不同种属石斛多糖对小鼠免疫功能的调节作用。方法: 培养小鼠脾淋巴细胞,观察不同浓度铁皮石斛、齿瓣石斛、兜唇石斛、晶帽石斛中多糖成分对小鼠脾淋巴细胞增殖的影响;研究口服给药不同剂量石斛多糖,对小鼠碳粒廓清能力、脾脏指数的影响。结果: 齿瓣石斛多糖可以刺激脾淋巴细胞的增殖,增加小鼠碳粒廓清能力和脾脏指数,与铁皮石斛具有类似的作用,而其他种类石斛中的多糖成分的增强免疫活性较差。结论: 齿瓣石斛多糖具有增强脾脏免疫的作用。

Abstract: AIM: To investigate the accommodation of polysaccharide extracts from different genus of Dendrobium to the immunologic function in mice. METHODS: The splenic lymphocytes of mice were cultured in different concentration of polysaccharide extracts from Dendrobium candidum, Dendrobium devonianum, Dendrobium aphyllum and Dendrobium crystallinum Tchb. F. After that the effect to splenic lymphocytes proliferation was observed. Treated mice by p.o. different doses of Dendrobium polysaccharide then determined carbon clearance capacity. RESULTS: Dendrobium devonianum polysaccharide extracts could stimulate lymphocyte proliferation, increase carbon clearance capacity and spleen index, had a similar function with Dendrobium candidum. The polysaccharide extracts from other Dendrobium had no activity in enhancing immunization. CONCLUSION: Dendrobium devonianum polysaccharide could enhance spleen immune function.
