Abstract
Using female dogs, changes in the urethral pressure profile in response to vesical distension were studied. It was noted that during the collecting phase there was an increase in the amplitude of the profile tracing. These experiments revealed that this increase is not mediated through an autonomic reflex and does not reflect a significant enhancement of alpha-adrenergic activity. These changes are mainly due to increased tension of the urethral muscle, secondly to detrusor stretch.
摘要
使用雌性犬研究了膀胱扩张时尿道压力曲线的变化。注意到在收集阶段，曲线描记的幅度增加。这些实验表明，这种增加不是通过自主反射介导的，也不反映α-肾上腺素能活性的显著增强。这些变化主要是由于尿道肌肉张力增加，其次是逼尿肌伸展。
