有50%的男性糖尿病患者有阳萎,而阳萎会引起病人心理上的负担。为了研究阳萎发生的病理学基础,探讨其发病机理,作者采用链脲菌素诱导的大鼠糖尿病模型,在光镜和电镜下对其阴茎进行了病理学研究。选用12只雄性路易士大鼠,体重125～160g,静注链脲菌素(65mg/kg),制成糖尿病模型。所有糖尿病大鼠和6只年龄配对的对照组大鼠都允许自由饮水和进行标准鼠食,未使用饮食限制或胰岛素治疗其高血糖。用葡萄糖分析仪测定血糖浓度。在 50% of men with diabetes have impotence, and impotence can cause the patient’s psychological burden. In order to study the pathogenesis of impotence and to explore its pathogenesis, the author used streptozotocin-induced diabetic rat model, under the light and electron microscope pathological study of the penis.
