摘要
目的探讨海绵体肌电图诊断脊髓性勃起功能障碍的价值。方法将24只成年雄性SD大鼠(300～400 g)分成:对照组、T9和L6损伤组(每组8只)。损伤脊髓1周后,用肌电图仪采集注射阿朴吗啡前后阴茎肌电数据,采集频率20～3 000 Hz、扫描速度5 ms／d、灵敏度10 μV／d。用t检验方法分析统计数据。结果对照组使用阿朴吗啡10 min均方根振幅为(5．60±0．89)μV, 大于T9损伤组(3．60±1．14)μV(P<0．05);使用阿朴吗啡前、使用后5 min和10 min高／低功率比均为0．05±0．03,小于L6损伤组0．13±0．04、0．15±0．07、0．13±0．07(P<0．05)。T9损伤组使用阿朴吗啡后5 min和10 min平均频率分别为(122．40±47．99)、(151．80±76．42)Hz,较L6损伤组(278．83±118．66)、(265．00±81．35)Hz低(P<0．05)。结论海绵体肌电图对脊髓性勃起功能障碍有诊断价值。
Objective To investigate the value of EMG of corpus eavernosum （CC-EMG） in diagneais of erectile dysfunction after spinal cord injury. Methods Twenty-four male adult SD rats were divided into three groups equally： controls, thoracic cord injured （T9） and lumbar cord injured （L6） groups. After one week of being spinal cord injured, aU experimental rats underwent CC-EMG with a cutoff frequency of 20-3000Hz, an amplitude of ±10μV and a monitor speed time of 5 ms/d under apomorphine s. c. Results Root mean square of the controls was （5.60 ± 0.89）μV, greater than （3.60 ± 1.14）μV in the thoracic cord injured at 10 min.High/low power around 1400/140 Hz of the controls was 0.05±0.03, less than that of the lumbar cord injured before and at 5 min and 10 min. Mean frequency of the thoracic cord injured was （122.40 ± 47.99）, （151.80 ±76.42）Hz, lower than （278.83 ± 118.66）, （265.00 ± 81.35） Hz of the lumbar ones 5 min and 10 min respectively after apomorphine s. c. （P〈0.05）. Conclusion It is possible to develop CC-EMG to diagnose spinal cord injured erectile dysfunction.
