Significant regional differences in the values of blood volume change response within one lobe of the lung upon the cervic sympathetic and parasympathetic nerves electrical stimulation have been demonstrated through the use of regional lung electroplethysmography method under the conditions of a minimal surgical trauma in dogs, cats, and rabbits kept in a supine position. The vascular component of the reaction has been isolated. It consists in blood volume increase in the lungs during the vagus stimulation and blood volume decrease during the sympathetic nerves stimulation. This response is very well manifested in central portions of the lung lobes and decreases progressively in peripheral direction. Blood volume changes due to different body positions relative to the gravitation direction have been demonstrated. Mechanisms of regional differences in blood volume changes have been discussed. The gravitation factor has been suggested to be also responsible for the formation of the neurogenic vasomotoric reaction in lungs.
通过在仰卧位的犬、猫和兔身上采用区域肺电阻抗容积描记法，在最小手术创伤的条件下，已证明在颈交感神经和副交感神经电刺激时，肺叶内血容量变化反应的值存在显著的区域差异。已分离出该反应的血管成分。其表现为迷走神经刺激时肺内血容量增加，交感神经刺激时血容量减少。这种反应在肺叶的中央部分表现得非常明显，并沿周边方向逐渐减弱。已证明了相对于重力方向的不同身体姿势导致的血容量变化。讨论了血容量变化区域差异的机制。有人提出重力因素也参与了肺神经源性血管运动反应的形成。
