1、湖北中医学院硕士学位论文速降糖对早期STZ糖尿病肾病大鼠保护作用的实验研究姓名:邱卫海申请学位级别:硕士专业:中医内科学指导教师:朱明方2003.6.1湖北中医学院硕士研究生毕业论文中文摘要目的通过观察速降糖对糖尿病大鼠血糖、血压、体重、肾重指数、尿素氮、肌酐、尿白蛋白排泄及肾组织转化生长因子$-、IV型胶原的影响,探讨该制剂对早期糖尿病肾病的保护作用及其机理,为进一步开发及临床应用提供实验依据。f寅强\采用腹腔注射链脲佐菌素(50mg/kg体重)的方法制备糖尿病大鼠模型52只,随机分为模型对照组(简称模
2、型组,12只)、速降糖小剂量组(简称小剂量组,lO只)、速降糖大剂量组(简称大齐j量组,10只),二甲双胍组(简称西药I组,10只)、二甲双胍合氯沙坦组(简称西药H组,lO只),再取10只正常大鼠作为正常对照组(简称正常组),共六组。各治疗组给予相应药物荆量灌胃,同时正常组及模型组给予等量的生理盐水灌胃,每日一次。治疗8周后,收集标本,检测血压、体重、血糖、肾重、血尿素氮和肌酐,用放免法测定尿白蛋白排泄量及通过免疫组化观察肾组织中转化生长因子pl的表达和IV型胶原的堆积。所有统计数据均用SPSSll0fo
3、rwindows进行统计学处理。结果1体重治疗前,各组大鼠体重无显著性差异。治疗后,速降糖大剂量组大鼠体重与模型组、西药I组和西药Ⅱ组比较,体重非常显著升高,P<0.01或P<0.05。小剂量组、大剂量组、西药Ⅱ组治疗前后无显著差异,P>0.05。2血糖治疗前,模型组和各治疗组血糖无显著差异,P>0.05;备治疗组与模型组比较血糖均非常显著性下降,P4、大鼠血压明显下降,P<005。4肾重指数与模型组相比,小剂量组、大剂量组和西药Ⅱ组的肾重指数均显著降低,PO.05。6尿白蛋白正常组和模型组有显著差异,P<0.05;小剂量组、大剂量组和西药Ⅱ组与模型组相比,尿白蛋白排泄显著降低,P5、P6、ebloodglucose、bloodpressure、bodyweight、kidneyweight、indexofkidneyhypertrophy(kidneyweight/bodyweight)、bloodurianitrogenandcreatinine、urinaryalbominexcretion(UAE)、expressionoftransforminggrownfactorD,(TGF一131)andaccumulationofcollagenlV(C-IV)inkidneytissue7、indiabeticratsinducedbyinjectingSTZintoabdomen.toinvestigatetllemechanismoftheprotectiveeffectontheearlydiabeticnephropathyandprovideanexperimentalbasisforfurtherdevelopingandclinicmedicatingSJtMethodsThediabeticratswereinducedbyinjectingStreptozotocinint8、otheirabdomensuccessfully,andtheywererandomlydividedintofivegroups:diabeticmodelgroup“modelgroup”(12rats)、lowdoseofSJTgroup“lowdosegroup”r10rats)、highdoseofSⅡgroup“highdosegroup”(10rats)、Metformingroup“drugIgroup”f1
