作者应用复式彩色超声监测阴茎血管反应,比较60mg罂粟碱和20μg前列腺素E_2(PGE_1)对阴茎血管的作用。材料与方法:34名年龄在24-66岁阳萎病人取平卧位复式彩色超声作检查,用Acuson128扫描仪5.0MH_2多普勒探头,在阴茎非勃起状态,测量其深动脉直径和动脉高峰收缩速率(PSV)。然后。给34 名病人注射60mg罂粟碱20μgPGE_1,间隔一定时间后,再测量上述两试验的的数据并将阴茎勃起分为四级:0级没有反应,1级轻微勃起,2级不完全勃起,3级正常勃起。所测得的数据做t检验处理。结果:没有病人在两试验中无反应。罂粟碱试验。3级勃起(14.7%)、2级(44.1%)、1级(41.2%)。PGE_1试验,3级勃起(17.6%)、2级(35.2%)、1级(47.1%)。两试验之间有很小的差别。罂粟碱和PG_1
The authors used penile color ultrasound to detect penile vascular responses and compared the effects of 60 mg of papaverine and 20 μg prostaglandin E_2 (PGE_1) on penile blood vessels. MATERIALS AND METHODS: Twenty-four patients aged 24-66 years with impotence were examined by duplex sonography. Acuson128 5.0MH_2 Doppler was used to measure the diameter of the deep arteries and the peak of the artery in the non-erect penis. Shrinkage rate (PSV). then. Thirty-four patients were injected with 60 mg of papaverine 20 μg PGE1. After a defined interval of time, the data from the two trials were re-measured and penile erections were divided into four grades: grade 0 with no response, grade 1 with slight erection, grade 2 with incomplete erection, grade 3 Normal erection. The measured data do t test. Results: No patient did not respond in both trials. Papaverine test. Grade 3 erection (14.7%), grade 2 (44.1%), grade 1 (41.2%). PGE_1 test, grade 3 erection (17.6%), grade 2 (35.2%), grade 1 (47.1%). There is a slight difference between the two tests. Papaverine and PG_1
