摘要: 为研究Ⅱ型糖尿病及其并发症发生的机理,预防和治疗Ⅱ型糖尿病药物和保健品的研究提供动物模型和基础资料,用高能量饲料结合低剂量链脲佐菌素(STZ,30mg/kg,腹腔注射)给予动物,建立Ⅱ型糖尿病动物模型,并对糖尿病并发症相关的指标进行测定。结果:试验组动物血糖升高,对胰岛素敏感性下降,造模成功与糖尿病并发症相关指标测定表明,血清中血清糖基化终产物-肽(AGE-P)水平升高,肾脏中醛糖还原酶(AR)活性显著高于正常对照组;同时血清中脂质过氧化产物(MDA)升高,而超氧化物歧化酶(SOD)水平下降。结论:本次实验Ⅱ型糖尿病模型大鼠造模成功,并出现了并发症发生的指标变化。

Abstract: Objective The purpose of this study is to provide animal model of diabetes Ⅱ and basic data for studying the development principle of the diabetes and diabetic complication. Methods:The rat model of diabetes Ⅱ was made by fed with a diet enriched with energy and ip low-dose streptozotocin (STZ 30mg/kg). The indexes related to the development of diabetic complication were detected. Results:The blood glucose level of treated rats was significantly higher than that of normal control rats,and the sensitivity to insulin was decreased. The level of advanced glyco-sylation end products-peptide (AGE-P) and lipoid peroxidation products malondialdehyde (MDA) in serum and the activity of aldose reductase(AR) in kidney of the diabetes model rats were remarkably increased, compared with whose of the control rats,whereas the superoxide dis-mutase (SOD) activity in serum of the models was significantly decreased. Conclusion:The diabetes Ⅱ rat model can be successfully established by fed with a diet enriched with energy and ip low-dose streptozotocin. The levels of indexes related to diabetic complication were changed. And this change may induce the development of diabetic complication.
