Vasomotor reactions to the increase of systemic blood flow by 100 ml/min occurred in anesthetized cats with left ventricular bypass: the increase of the pulsatile flow produced reflex vasodilatation, while its reduction to the initial value entailed vasoconstrictor reflex. In case of pulsatile perfusion responses of resistance vessels to the same change of systemic flow included opposite reflex and myogenic factors. Inhibition of the systemic myogenic vascular tone in absence of pulse alterations of pressure and flow is discussed.
在进行左心室旁路手术的麻醉猫中，当全身血流量增加100毫升/分钟时会出现血管运动反应：搏动性血流增加会引起反射性血管舒张，而当血流降至初始值时则会引发血管收缩反射。在搏动灌注的情况下，阻力血管对全身血流相同变化的反应包括相反的反射和肌源性因素。本文还讨论了在压力和血流无脉冲变化的情况下全身肌源性血管张力的抑制作用。
