目的:应用链脲佐霉素(STZ)建立糖尿病豚鼠模型,观察糖尿病膀胱病(DCP)的病程进展,探究平滑肌特异性蛋白Smoothelin在其发病机制中的表达改变以及意义。 方法:50只英国种短毛雌性豚鼠,随机选择42只作为实验组,8只作为对照组。实验组单次腹腔注射链脲佐菌素(STZ),对照组注射相应剂量的枸橼酸缓冲液。全价饲养9周和12周,尾静脉取血通过血糖筛选确定入组豚鼠,中下腹部切开活体暴露膀胱并应用尿动力仪检测残余尿、排尿期最大逼尿肌压、膀胱容量及顺应性的变化,以逼尿肌收缩最大压力下降以及残余尿/膀胱容量Objective To investigate the expression of Smoothelin in urinary bladder of streptozotocin-induced diabetic guinea pigs and the possible mechanisms of diabetic cystopathy. MethodsFifty female guinea pigs were randomly divided into STZ-induced diabetic(42) and normal control(8). Urodynamic study was to evaluate the changes of bladder functionand and distinguish the diabetic cystopathy group among...学位:医学硕士院系专业:医学院_外科学学号:2452011115339
