Description

一种用于改善肥胖和降低血脂的复合益生菌制剂
技术领域
本发明涉及一种复合益生菌制剂,特别是一种用于改善肥胖和降低血脂的复合益生菌制剂。
背景技术
妊娠期的肥胖是影响母婴健康的公共卫生问题。妊娠期的肥胖导致围产期的并发症如高血压、高血脂、高血糖等的发病率升高;同时母亲的肥胖是导致肥胖特质在代际间传递的关键因素。妊娠期母亲的肥胖也是预测子代肥胖的最佳预测指标。而儿童期肥胖的个体更容易发展为成年期的肥胖,影响远期的健康水平。因此,超重及肥胖的孕妇不仅影响自身的健康同时对子代的健康构成远期影响。目前世界范围内针对肥胖的改善手段非常有限。
肠道菌群作为人体被遗忘的器官,参与机体的免疫、代谢、发育等正常的生理功能。近年来关于肠道菌群与肥胖的关系成为国际研究的热点。尤其是厚壁菌门与拟杆菌门的比例变化可能是肥胖发生的始动及持续因素。肥胖孕妇其存在肠道菌群失衡,肥胖孕妇所产子代出现肥胖的比例升高,目前缺少切断肥胖母亲对子代代谢不利影响的有效手段。
发明内容
本发明提出了一种能够有效改善肥胖和降低血脂的复合益生菌制剂。
本发明的技术解决方案是:一种用于改善便秘的复合益生菌制剂,其特征在于:所述的复合益生菌制剂由以下益生菌按照一定的活菌数量混合而成:短双歧杆菌(Bifidobacterium breve):嗜酸乳杆菌(Lactobacillus acidophilus):干酪乳杆菌(Lactobacillus casei):嗜热链球菌(Sterptococcus Thermophilus)的比例为0.5-1.5:0.5-1.5:0.5-1.5:0.5-1.5;更为优选的比例为0.5-1:0.5-1:0.5-1:0.5-1;优选的比例为1:1:1:1,且混合后的复合益生菌制剂总活菌数量为至少20亿/mL,以这样一个比例用于动物实验。这是一种能够改善肥胖和降低血脂的复合益生菌制剂。
上文所述的短双歧杆菌(Bifidobacterium breve)、嗜酸乳杆菌(Lactobacillusacidophilus)、干酪乳杆菌(Lactobacillus casei)、嗜热链球菌(SterptococcusThermophilus)菌种都可以从现有的菌种库中购买获得,菌种号如下:短双歧杆菌(Bifidobacterium breve)15700TM*、嗜酸乳杆菌(Lactobacillus acidophilus)314TM、干酪乳杆菌(Lactobacillus casei)393TM*、嗜热链球菌(Sterptococcus Thermophilus)19258TM
本发明主要是利用现有的益生菌进行有机组合,其复合菌剂给予肥胖母体于妊娠期、哺乳期应用,研究表明其对肥胖母体及子代菌群紊乱、血脂代谢紊乱的改善作用,且其对子代的菌群及血脂改善作用可持续到成年期。

具体实施方式
下述非限制性实施例可以使本领域的普通技术人员更全面地理解本发明,但不以任何方式限制本发明。
实施例1
对妊娠期肥胖动物模型的研究
取上述短双歧杆菌(Bifidobacterium breve)、嗜酸乳杆菌(Lactobacillusacidophilus)、干酪乳杆菌(Lactobacillus casei)、嗜热链球菌(SterptococcusThermophilus)分别培养,收集菌体后使用生理盐水配制成混合菌悬液。选用SPF级C57BL/6J大鼠随机分为3组,分别为空白对照组,肥胖模型组,益生菌干预组,分别给予标准饲料(70%碳水化合物,20%蛋白质,10%脂肪)、高脂饲料(35%碳水化合物,20%蛋白质,45%脂肪)、高脂饲料同时每天给予益生菌(20亿)灌胃,饲养6周,6周后雌雄合笼,妊娠期及哺乳期分别为21天,子鼠母乳喂养21天后,全部给予标准饲料。检测母鼠妊娠第1天、子鼠21天及42天菌群的变化,分析母鼠及子鼠的体重及血脂变化。
各组小鼠体重变化情况
见图1,母鼠体重的结果显示肥胖模型组母鼠的体重明显高于对照组,复合益生菌合剂干预组母鼠体重明显低于肥胖模型组。子鼠体重的结果见图2,肥胖组子鼠体重明显高于对照组,复合益生菌合剂干预组子鼠体重明显低于肥胖组子鼠体重。
各组小鼠肠道菌群的变化
见表1,母鼠妊娠第1天肠道菌群变化的结果显示,高脂饮食导致母鼠肠道菌群α-多样性中的Chao1及Shannon指数高于正常组,复合益生菌合剂干预能够降低高脂饮食诱导的母鼠肠道菌群的α-多样性。

图1,针对母鼠肠道菌群门水平的分析结果显示各组间在门水平的差异不显著,然而在属水平:Bacteroidetes S24-7,Allobaculum及Sutterella在肥胖组的相对含量较正常组明显降低,复合益生菌合剂干预能够增加Bacteroidetes S24-7,Allobaculum及Sutterella的相对含量。此外肥胖组母鼠Lachnospiraceae,Bacteroides,Prevotella,Mucispirillum,Helicobacter,Rikenellaceae及Ruminococcaceae的含量高于正常对照组,复合益生菌合剂干预能够降低这些菌的含量。
针对子鼠21天(断乳期)及42天(成年期)肠道菌群检测的结果见表1,子鼠雌性21天肠道菌群的α-多样性中的Chao1及Shannon指数低于正常组,复合益生菌干预组雌性子鼠的α-多样性高于肥胖鼠子鼠。
