Pulmonary arteries and veins reacted by constriction to electric activation of rostrally located medulla oblongata ventral structures (lateral paragiant-cell nucleus area) in acute cat experiments. In contrast to this, electric stimulation of medulla oblongata caudal ventral structures induced dilatation of lesser circulation vessels. Counter-phase changes in parameters characterizing pulmonary microhemodynamics (capillary hydrostatic pressure, capillary filtration index) in response to electric stimulation of the studied brain structures permit a conclusion on the high homeostatic parameters of pulmonary microcirculation when maintaining ventilation perfusion relationships.
在急性猫实验中，肺动脉和静脉对位于延髓前部腹侧结构（外侧巨细胞旁核区域）的电刺激产生收缩反应。与此相反，电刺激延髓尾部腹侧结构会导致小循环血管扩张。响应于对所研究脑结构的电刺激，表征肺微循环动力学的参数（毛细血管流体静压、毛细血管滤过指数）出现反相变化，这使得我们可以得出结论，在维持通气灌注关系时，肺微循环具有高度的稳态参数。
