目的:用高脂饲料加小剂量STZ腹腔注射建立实验性2型糖尿病大鼠模型。方法:Wistar大鼠,分为正常对照组、高脂饲料组、小剂量STZ组和高脂饲料加小剂量STZ组,每10 d测定大鼠血浆总胆固醇(TC)、甘油三脂(TG)、高密度脂蛋白-胆固醇(HDL-C)和血浆胰岛素及其反调激素胰高血糖素及皮质酮水平,连续50 d。结果:各组TC均有升高,高脂饲料组明显;高脂饲料组、高脂饲料加小剂量STZ组血浆TG水平升高;小剂量STZ组血浆HDL-C明显降低;小剂量STZ组和高脂饲料加小剂量STZ组血浆胰岛素和胰高血糖素水平降低,高脂饲料组血浆皮质酮水平有升高趋势,小剂量STZ组升高明显。结论:高脂饲料加小剂量STZ腹腔注射诱发2型糖尿病大鼠模型具有高血脂特点,血浆糖代谢相关激素水平可受影响。
Objective:To establish and evaluate type 2 diabetic rat model induced by both high lipids food feeding and low dose STZ(ip).Methods: Wistar rats were randomly divided into four groups: control group,high lipids food group,low dose STZ group,and both high lipids food and low dose STZ group.Plasma lipids level and hormone levels related to glucose metabolism were determined,compared and evaluated every ten days for fifty days in each group.Results:Plasma total cholesterol(TC) in treated group,especially in hi...
