Abstract
The influence of vesical distension of the urethral pressure profile was studied in female dogs, using a model in which the bladder and urethra were separated. There was a reduction in the urethral resistance involving its smooth and striated muscle components. This reduction was completely blocked by ganglion blocking agents. Atropine did not influence these changes. Propranolol could only partially block this reflex. The other possible mechanisms that could be involved were discussed.
摘要
利用膀胱和尿道分离的模型，研究了雌性犬膀胱扩张对尿道压力曲线的影响。尿道阻力降低，涉及平滑肌和横纹肌成分。这种降低被神经节阻断剂完全阻断。阿托品不影响这些变化。普萘洛尔只能部分阻断这种反射。文中讨论了可能涉及的其他机制。
