摘要 目的:证实链脲佐菌素(STZ)腹腔注射法建立大鼠糖尿病性勃起功能障碍(ED)模型的可行性。方法:60只SD大鼠随机分为对照组(10只)和试验组(50只)。试验组按照50mg/kg的剂量单侧腹腔注射即时配制的STZ溶液。对照组单侧腹腔注射同等量的柠檬酸-柠檬酸钠缓冲液0.1mol/L。第4天测血糖,以随机血糖>16.7mmol/L定为建模标准;平均每周监测血糖1次,10周后将阿朴吗啡(APO)按100μg/kg比例皮下注射于大鼠颈部皮肤松软处,观察大鼠阴茎勃起情况。结果:实验组糖尿病成模率为94%(47/50),有3只大鼠出现STZ抵抗,成模后10周相继有10只大鼠死亡;试验组血糖明显高于正常对照组(P<0.01),体重、阴茎勃起次数、阴茎勃起率则明显低于对照组(P<0.01)。结论:STZ 50mg/kg单侧腹腔内注射能安全有效地建立大鼠糖尿病模型,颈部皮下注射APO 100μg/kg可有效地筛选出大鼠糖尿病勃起功能障碍。
