摘要: |
目的研究自发性2型糖尿病GK大鼠随病程进展的病理生理和组织形态学改变。方法选择自发性2型糖尿病GK大鼠为糖尿病动物模型,同源Wistar大鼠为正常对照组,检测其血糖、血脂、血胰岛素等生化指标,定期行口服葡萄糖耐量试验检测血糖,HE染色观察心肌和胰腺组织形态学改变。结果自发性2型糖尿病GK大鼠生长缓慢,体重随病程延长与正常对照组呈显著差异(P〈0.05);血糖轻、中度升高(P〈0.05)。血清甘油三酯水平显著升高,血清总胆固醇水平亦升高(P〈0.05)。GK大鼠呈高胰岛素血症,胰岛素抵抗指数也较对照组有统计学意义(P〈0.05)。胰岛在病程早期表现为肥大增生,晚期破坏、纤维化程度明显高于Wistar大鼠;GK大鼠心肌横纹欠清晰,纤维排列稍扭曲紊乱,部分可见心肌细胞溶解和间质纤维化。结论自发性2型糖尿病GK大鼠表现为轻中度高血糖、中度胰岛素抵抗,血脂升高,胰岛功能不足和温和的糖尿病心肌病变,且不伴随肥胖,是良好的2型糖尿病动物模型。 |
