摘要 目的制备与人类发病过程类似的伴高血压2型糖尿病大鼠模型。方法选择40只SPF级雄性Wistar大鼠随机分为对照组12只和实验组28只,对照组以标准大鼠饲料饲喂,实验组以高脂高盐饲料喂养,两组均饮用大鼠专用去离子水,16w进行正糖钳实验,确定胰岛素抵抗,腹腔注射链脲佐菌素(STZ)造成2型糖尿病。实验过程中每周测食量、水量和体重,每4w测血糖和尾动脉血压,实验16w时取血测空腹血浆胰岛素。结果饲喂高脂高盐饲料16w后,与对照组相比,实验组尾动脉血压明显升高,差异显著(P<0.01);实验组空腹胰岛素浓度明显高于对照组(P<0.01);与对照组相比,实验组葡萄糖输注速率明显降低,两组差异有统计学意义;STZ注射后实验组血糖明显升高,达到了糖尿病的诊断标准。结论高脂高盐饮食配合STZ腹腔注射可成功诱导出伴高血压2型糖尿病大鼠模型。
