Abstract

In anesthetized cats and rabbits responses of terminal pulmonary vessels to alveolar hypoxia, noradrenaline, histamin, acetylcholine and serotonine, were studied. The role of the vascular bed tone in regulation of pulmonary filtration-absorption function, was studied. A low motor activity of pulmonary microvessels was found. Their contribution to hemodynamic shifts in microcirculation was insignificant. Pulmonary vasomotor responses cannot be a reason for considerable extravascular accumulation of fluid in the lungs at a normal hydraulic permeability of alveolar-capillary membrane.

摘要

在麻醉猫和兔身上,研究了终末肺血管对肺泡缺氧、去甲肾上腺素、组胺、乙酰胆碱和血清素的反应。研究了血管床张力在肺滤过-吸收功能调节中的作用。发现肺微血管的运动活性较低。它们对微循环中血流动力学变化的贡献微不足道。在肺泡-毛细血管膜正常水力通透性的情况下,肺血管运动反应不可能是肺内液体大量血管外积聚的原因。
