title: [Blood filling and elasticity of pulmonary vessels after section and stimulation of the vagus nerve].
abstract: Blood content and elasticity of lung vessels in the central and peripheral portions of the posterior lung lobes were measured in experiments on dogs with intact chest using regional electroplethysmography of the lungs and catheterization of pulmonary artery branches. Electric stimulation of vagosympathetic nerves in the central portion of the pulmonary lobe might give rise to a considerable increase in lung lobe blood content due to a neurogenic vasodilatory effect without pressure elevation in lung vessels. However, further increase in blood content was confined to reduced elasticity of these vessels and was hardly possible without a noticeable pressure rise in pulmonary circulation.
