观察低出生体重大鼠不同发育时期骨骼肌形态结构的变化和胰岛素抵抗情况.采用孕期低蛋白饮食法建立低出生体重仔鼠模型.于出生后7 d、21 d、2月龄测定仔鼠空腹血糖、血清胰岛素值,并检测骨骼肌形态结构.自7 d至2月龄,低出生体重仔鼠骨骼肌纤维均有明显萎缩、排列稀疏紊乱;2月龄时超微结构明显异常.2月龄内低出生体重仔鼠血糖和血清胰岛素与对照组比较无差异.

To study the changes in skeletal muscle structure and insulin resistance of low birth weight rats.The low birth weight filial rat model was established by feeding low protein diet to the pregnant rat during gestation.At 7 d,21 d,and 2 months,blood glucose and serum insulin were measured,and the structure of skeletal muscle was observed.From 7 d to 2 months,the muscle fibers of low birth weight rat were atrophic and arranged in disorder.The ultrastructure of skeletal muscle was also abnormal distinctly at 2 months.No differences of blood glucose and rerum insulin were found between the two groups.
