摘要/Abstract

摘要： 选取60只30日龄雄性SD大鼠,随机分成4组,分别是对照常氧、对照低氧、试验常氧和试验低氧组,对照组饲喂基础日粮,试验组饲喂含亚麻籽油日粮,试验持续4周,研究亚麻籽油和低氧处理对动物采食量和体增重、血糖和肝脏脂肪利用等的影响。结果发现,雄性SD大鼠采食量和体增重不受日粮亚麻籽油影响,但低氧处理可显著降低大鼠采食量和体增重。低氧和亚麻籽油均能促进骨骼肌葡萄糖转运蛋白-4(GLUT4)mRNA的表达,但对总血糖没有显著影响;增加了肝脏过氧化物酶体增殖物激活受体-γ(PPARγ)mRNA表达和脂蛋白脂酶活性,促进低密度脂蛋白的分解,增加高密度脂蛋白含量。亚麻籽油在脂肪利用方面与低氧具有交互作用,能改善低氧时的能量不足。
