Effect of Bifidobacterium fermented mixed fruit and vegetable juice on immunological function of mice

目的研究双歧杆菌发酵果蔬汁对小鼠免疫功能的影响。方法将小鼠随机分成纯净水对照组与发酵果蔬汁低、中和高3个剂量组,饮水法喂饲小鼠,测定小鼠胸腺和脾脏指数、腹腔巨噬细胞吞噬功能、血清溶血素测定、皮肤迟发型超敏反应(DTH)程度。结果与对照组比较,3种果蔬汁能显著增强巨噬细胞吞噬功能,增加血清溶血素抗体水平和DTH程度。结论双歧杆菌发酵果蔬汁能提高机体的免疫功能。

Objective To explore the effect of Bifidobacterium fermented mixed fruit and vegetable juice on immunological function of mice.Method Mice were randomly assigned to 10 groups：purified water control group and 3 groups of fermented mixed fruit and vegetable juice with low,medium and high dose respectively.The index of thymus and spleen,phagocytic capability of celiac macrophage,level of serolysin and degree of cutaneous delayed type hypersensitivity of mice were evaluated.Result The phagocytic capability of celiac macrophage,the level of serolysin and the degree of cutaneous delayed type hypersensitivity of all 3 groups of fermented mixed fruit and vegetable juice increased significantly compared with those of control group.Conclusion Bifidobacterium fermented mixed fruit and vegetable juice can enhance the immunological function of mice.
