摘要: 试验旨在探讨党参多糖(CPPS)和硒化党参多糖(sCPPS5)对环磷酰胺(CY)所致免疫抑制小鼠免疫功能的影响。将96只小鼠随机分为8组,分别为正常对照组、CY模型组、CY+CPPS低、中、高剂量组、CY+sCPPS5低、中、高剂量组。正常对照组和CY模型组给予生理盐水,其余每组均用CPPS和sCPPS5按0.2、0.4、0.6 mg/g灌胃小鼠,每天1次,连续给药10 d。第11天,除正常对照组外,其余组分别腹腔注射0.04 mg/g CY,每天1次,连续3 d。各试验组末次给药24 h后,检测各组小鼠免疫学指标。结果显示,CPPS和sCPPS5各组的脾脏、胸腺指数均显著高于CY模型组(P < 0.05);刀豆蛋白A (ConA)和脂多糖(LPS)刺激时,CPPS和sCPPS5试验组的A570 nm值显著高于CY模型组(P < 0.05);CPPS和sCPPS5试验组IgG和IgM的含量显著高于CY模型组(P < 0.05),sCPPS5效果优于CPPS;综述所述,CPPS和sCPPS5均能够增强免疫抑制小鼠的免疫活性,硒化修饰后的CPPS效果优于未硒化修饰的CPPS,说明硒化修饰可以提高多糖的免疫活性。

Abstract: The study was aimed to observe the effects of Codonopsis pilosula polysaccharides(CPPS) and selenium-Codonopsis pilosula polysaccharides5(sCPPS5) on the immune functions of immunosuppressive mice induced by cydophosphamide (CY).96 mice were randomly divided into 8 groups:Normal control group,CY model group,CY+CPPS (low,middle and high dose groups) and CY+sCPPS5 (low,middle and high dose groups).Mice in normal control group and CY model group were lavaged with normal saline,the mice in other groups were lavaged with CPPS and sCPPS5 by 0.2,0.4 and 0.6 mg/g,respectively.Administration was carried out once a day for 10 successive days.On the 11th day,mice were manufactured immunosuppressed by a three-day intraperitoneal injection of 0.04 mg/g CY,except for the normal control group.After administrated with drugs for 24 h,the immunological indexes of the mice were detected.The results showed that spleen and thymus indexes of CPPS and sCPPS5 groups were significantly higher than that of CY group (P < 0.05).The A570 nm when stimulated with ConA and LPS,serum IgG and IgM contents of CPPS and sCPPS5 groups were significantly higher than that of CY group (P < 0.05) and sCPPS5 possessed better efficacy than CPPS.In conclusion,CPPS and sCPPS5 could strengthen immune activity of the immunosuppressive mice,but sCPPS5 was better than CPPS and selenylation modification could improve the immune activity of polysaccharide.
