Abstract:

该研究采用小剂量链脲佐菌素(STZ)尾静脉注射和高脂饮食8周建立大鼠T2DM模型,给予交泰丸治疗,检测葡萄糖耐量试验(OGTT)、空腹胰岛素(FINS)、游离脂肪酸(FFA)、血脂,计算胰岛素抵抗指数(HOMA-IR),胰腺组织病理学检查,脂质抽提法检测胰腺组织甘油三酯(TG)含量,原位末端脱氧核糖核苷酸转移酶介导dUTP标记法(TUNEL)法检测胰岛细胞凋亡情况。结果显示,模型组OGTT异常,FINS,HOMA-IR,FFA升高,血脂紊乱,胰腺组织见明显脂肪沉积,胰腺组织TG含量明显升高,胰岛细胞凋亡增加;与模型组比较,交泰丸组OGTT改善,FINS,HOMA-IR,FFA下降,血脂紊乱好转,胰腺组织脂肪沉积减少,胰腺组织TG含量明显下降,胰岛细胞凋亡减少。综上所述,交泰丸可有效治疗大鼠T2DM,其机制可能与减少胰腺脂肪沉积和胰岛细胞凋亡有关。
