摘　　要：研究黑米对小鼠肠道菌群及其相关指标的影响。24只昆明(KM)小鼠随机分成4个组:组1(饲喂基础饲料)、组2(饲喂30%黑米和70%基础饲料的混合饲料)、组3(饲喂60%黑米和40%基础饲料的混合饲料)、组4(饲喂90%黑米和10%基础饲料的混合饲料)。第6周收集小鼠粪便测定粪便含水率,第42天测定血清总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)以及肠道双歧杆菌、乳酸杆菌、肠球菌和肠杆菌数量。结果表明,与组1小鼠相比,摄入黑米后,试验组小鼠结肠双歧杆菌数和乳酸杆菌数显著上升(P<0.05),组2最高,其次是组3和组4;肠杆菌科数显著下降(P<0.05),组2最低,组4次之;组2和组4肠球菌数显著低于组1(P<0.05)。试验组小鼠的血清HDL-C和HDL-C/TC都显著高于组1(P<0.05),组4的HDL-C最高,组2的HDL-C/TC最高。表明摄入全谷黑米可以提高小鼠肠道益生菌数量,全谷黑米对肠道具有益生作用。Effects of black rice on intestinal flora of mice were investigated in this research.24 KM mice were divided into four groups at random and fed with the regular food（group 1）,mixed food（group 2,70% regular food combined with 30% black rice）,mixed food（group 3,40% regular food combined with 60% black rice）,and mixed food（group 4,10% regular food combined with 90% black rice） respectively.Fecal moisture contents were determined everyday in the 6th week,and serum total cholesterol（TC） and high density lipoprotein cholesterol（HDL-C） were also determined at the end of 6th week.Intestinal Bifidobacterium,Lactobacillus,Enterococcus and Enterobactericaeae were numbered by plate count method.As compared to the group 1,the numbers of bifidobacterium and lactobacillus in other 3 group increased significantly by intake of black rice;the numbers of Enterobacteriaceae and Enterococcus decreased significantly.Serum HDL-C and HDL-C/TC levels were also increased significantly by intake of black rice.Results clearly indicated that intake of black rice can increase the number of intestinal probiotics in mice.
