| 摘 要： | 目的 探讨氧化应激在糖尿病性阴茎勃起功能障碍（ED）中的作用。 方法 注射链脲佐菌素建立糖尿病大鼠模型，分别在注射8周和12周后观察阴茎勃起次数；取大鼠阴茎，测定阴茎丙二醛水平、总抗氧化能力，免疫印迹法检测阴茎核因子E2相关因子2(Nrf2)蛋白量的变化。 结果 糖尿病大鼠的阴茎勃起次数明显低于对照组，并随病程延长降低；糖尿病大鼠阴茎丙二醛水平明显高于对照组，总抗氧化能力水平明显低于对照组；与对照组比较，糖尿病组大鼠阴茎内Nrf2蛋白量随病程延长而降低。 结论 糖尿病性阴茎勃起功能障碍与阴茎氧化应激水平升高相关。

| Abstract: | Objective To investigate the effect of oxidative stress on diabetic erectile dysfunction( ED). Methods Diabetes mellitus(DM) was induced by streptozotocin (STZ) injection. Eight weeks and twelve weeks later, penis erectile function was detected by injecting apomorphine. The concentrations of malondialdehyde ( MDA) and total anti-oxygen capability (T-AOC) in penis were measured. Western blotting was used to measure nuclear factor E2 related factor 2（Nrf2） in both control and diabetic rat penis tissues in present study. Results Compared with control group, the erection times of DM rats decreased significantly. The mean level of MDA in penis of DM rats were higher than that of control group（EM>P/EM>﹤0.01）, and the mean level of T-OC in DM rats was lower than that of control（EM>P/EM>﹤0.05）. Nrf2 protein expression decr |
