Changes of skeletal muscle structure and insulin resistance in low birth weight rat / 中华内分泌代谢杂志

ABSTRACT

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.
