用贵州小香猪建立一种新的2型糖尿病合并动脉粥样硬化模型,探讨高脂高蔗糖饲料对糖、脂代谢的影响.采用高脂高蔗糖饲料饲喂贵州小香猪,观察其体重、血糖、胰岛素和血脂的变化,并对胰岛β细胞功能、脂质在主动脉和肝脏组织沉积进行研究.结果发现,喂养8个月后,与正常对照组比较:实验组空腹血糖值明显升高,血清总胆固醇、甘油三酯水平升高,脂肪细胞肥大,胰岛β细胞受损,主动脉出现脂纹,内膜增厚,肝脂肪样变性.以上结果说明,高脂高蔗糖饲料可诱导贵州小香猪发生胰岛素抵抗、糖尿病和动脉粥样硬化,此模型适用于糖尿病并发脂代谢紊乱和动脉粥样硬化及其治疗的研究.

Aim To establish a new animal model of the human type 2 diabetes mellitus complicated with atherosclerosis and investigate the effects of high fat/high sucrose feeding on glucose and lipid metabolism in guizhou minipigs. Methods Minipigs were fed with high fat/high sucrose diet (HFSD) and the levels of fasting blood glucose, insulin, total cholesterol, triglycerides were measured. Dysfunction of the pancreatic β-cell were observed by immunohistochemistry. The aortic fatty streak-lesions were quantified following lipid staining with Sudan IV. L...
