  探究枯草芽孢杆菌B10对高脂日粮诱导的小鼠的脂肪代谢及氧化应激的改善作用,并初步探讨其作用机制。将C57BL/6J雄鼠分为对照组(饲喂高脂日粮)和实验组(饲喂添加有枯草芽孢杆菌菌粉的高脂日粮)。饲喂30天后,收集小鼠的血清及肝脏样品。采用试剂盒测定抗氧化及脂肪代谢相关指标和肝脏中8-OHdG含量。使用荧光定量PCR测定小鼠肝脏中脂肪代谢和氧化应激相关基因的表达水平。饲喂含有枯草芽孢杆菌B10的高脂日粮能够有效降低小鼠的体重,减少血糖含量,降低血清中三油酸甘油酯含量及谷草转氨酶和谷丙转氨酶活力;下调肝脏中脂肪合成相关基因表达量,但上调脂肪分解相关基因表达量,并提高肝脏中抗氧化相关基因表达量。综上所述,枯草芽孢杆菌B10能有效调节小鼠脂肪代谢,并改善其氧化应激。
