title: [Experimental study of corpus cavernosal nerve evoked potential in diabetic rats].
abstract: OBJECTIVE
  To observe the cavernosal nerve dysfunction of diabetic Sprague Dawley rats.
  
  
  METHODS
  Thirty-five Sprague-Dawley rats were divided randomly into diabetes model group(n = 25) and normal group(n = 10). Diabetes model was established by administration of streptozotocin (63 mg/kg) in single intraperitoneal dosing. Giving single wave stimulus, corpus cavernosal nerve was measured for its latent period of reaction and myopotential.
  
  
  RESULTS
  Compared with other groups, diabetic rats had longer reflection latent period(P < 0.01) and higher corpus cavernosum smooth muscle myopotential (P < 0.01).
  
  
  CONCLUSIONS
  The results indicate that corpus cavernosal nerve dysfunction may play an important role in the erectile dysfunction of diabetic rats.
