【摘要】 研究海带多糖对小鼠肠黏膜组织SIgA及肠道菌群的影响。将40只昆明种小鼠随机分为4组,分别以250、500、1000μg/g的海带多糖灌胃小鼠15d,以灌胃蒸馏水小鼠为对照,分别取小肠黏膜、肠道粪便,采用试剂盒法测小肠黏膜组织的SIgA活性;采用微生物培养培养鉴定的方法计数粪便中双歧杆菌、乳杆菌和肠杆菌。结果显示500、1000μg/g的海带多糖能够促进小鼠肠黏膜对SIgA的分泌量并且能够增加肠道中乳杆菌数量;1000μg/g的剂量能增加肠道中双歧杆菌的数量;各剂量组对粪便中肠杆菌的量没有影响。由此提示海带多糖能够促进小鼠的肠道免疫。更多还原

【Abstract】 To observe the influence of Laminarina Japonica Polysaccharides (LJPS) on intestinal immunity SIgA and intestineal flora in mice. The mice were fed LJPS at doses of 250, 500, 1000 μg/g. By ELISA kit, The effect of LJPS on intestinal immunity SIgA activity were evaluated in normal mice. By microbial cultivation, the number of intestinal flora were observed. LJPS 500, 1000 μg/g enhanced secretion of SIgA and the number of Lactobacillus in mice, and LJPS 1000 μg/g enhanced the number of Bifidobacterium. It showed that LJPS increased secretion of SIgA and regulated intestinal flora in mice.更多还原
