摘要: 试验旨在探讨乳酸菌―芽孢菌发酵黄芪对小鼠免疫功能的影响。将84只小鼠分成6组,每组14只,分别为生理盐水组(阴性对照组)、未发酵黄芪组(阳性对照组,黄芪生药浓度为150 mg/mL)、试验Ⅰ组(黄芪生药浓度为60 mg/mL)、试验Ⅱ组(黄芪生药浓度为90 mg/mL)、试验Ⅲ组(黄芪生药浓度为120 mg/mL)、试验Ⅳ组(黄芪生药浓度为150 mg/mL)。小鼠采用灌胃方式给药30 d,最后处死小鼠测定其体重、免疫器官(胸腺和脾脏)系数、免疫因子(IgG、IL-6、sIgA)。结果显示,给药30 d后,试验组小鼠体重明显升高;试验Ⅰ组免疫器官系数极显著高于对照组(P<0.01);试验Ⅲ、Ⅳ组免疫因子IgG和sIgA均极显著高于对照组(P<0.01)。由此可知,乳酸菌―芽孢菌发酵黄芪对小鼠的免疫功能有很好的促进作用。

Abstract: The assay was aimed to investigate the immune effects of Radix astragalus fermented by Lactobacillus and Bacillus. Eighty-four mice were divided into six groups that were physiological saline group (negative control group), non-fermented Radix astragalus group (positive control group, 150 mg/mL), group Ⅰ(60 mg/mL), group Ⅱ (90 mg/mL), group Ⅲ (120 mg/mL), group Ⅳ (150 mg/mL). Mice were given medicine by gavage for 30 d and then they were killed to detect the weight, the immune organ (thymus and spleen) index and immune factor (IgG, IL-6, sIgA). The results indicated that the weight of experimental groups apparently rose; the immune organ index of group Ⅰ was extremely significantly higher than that of the control group (P<0.01), but the immune factor (IgG/sIgA) of groups Ⅲ and Ⅳ extremely significantly exceeded the control group (P<0.01). Finally, there were obviously promotional effects of Radix astragalus fermented by Lactobacillus and Bacillus on immune function of mice.
