摘要 目的:建立简便、稳定并符合临床病理特征的去垂体中枢性尿崩症大鼠模型。方法:将80只雄性Wistar大鼠随机分为对照组和模型组,模型组大鼠40只,通过立体定向垂体切除仪经耳道吸除垂体,2组大鼠均经代谢笼收集24h尿,24h后处死大鼠心脏取血放免法检测血浆ADH浓度,并在显微镜下解剖蝶鞍区观察垂体摘除是否完全。结果:立体定向去垂体性尿崩症模型成功率92.5%(37/40),去垂体大鼠存活率97.30%(36/37),模型组大鼠术后尿崩症状明显,尿量达(2.44±0.30)mL/h,对照组大鼠尿量为(0.46±0.14)mL/h(P<0.01);模型组大鼠尿比重(1.011±0.002)低于对照组(1.034±0.003)(P<0.01),血浆ADH浓度(230.73±13.30)ng/L,低于对照组(951.32±23.11)ng/L(P<0.01)。结论:立体定向去垂体可以建立稳定的尿崩症大鼠模型。
