lobeline/hypoxia

The role of the autonomic nervous system on the pulmonary vascular response to hypoxia was studied in anesthetized open-chest dogs. Acute hypoxia elicited reversible decreases in the slope of the instantaneous diameter-pressure relationship of the main pulmonary artery. These decrements in vascular

The effect of various cardiovascular reflexes and reactions on the plethysmographically recorded penile volume in rabbit was investigated. Stimulation of the aortic nerve or direct stimulation of the carotid sinus produced increase in penile volume, while carotid occlusion produced decrease. Brief

Perfusion of thrombin and trypsin solutions through the frog carotid labyrinth acts on the carotid chemoreceptors and evokes reflex response of the anticoagulating system. The similarity of effects of both these agents seems to be due to similarity of their structures. Other agents acting on the

1. A technique for the perfusion of the rabbit liver with Krebs solution is described: the hepatic nerves were monitored for centripetal action potentials. Spontaneous afferent activity, and a good response to stimulating agents persisted for 7 h or longer.2. Action potentials were elicited by

We examined the effects of chemical and reflex drives on the postinspiratory inspiratory activity (PIIA) of phrenic motoneurons using a single-fiber technique. Action potentials from "single" fibers were recorded from the C5 phrenic root together with contralateral mass phrenic activity (also from
