Reflex control of vascular tone in anaphylactic shock

Communication I. The state of the pressor reflexes during hypotension due to anaphylactic shock

Pathological Physiology and General Pathology


Experiments were conducted on rabbits and dogs under conditions of anaphylactic shock of medium intensity. The pressor reflexes inhibited at the beginning of the arterial hypotension not only recover their function but even become intensified, in comparison with the normal condition. This indicated that in the given state the ability of the vasomotor center to respond to the pressor stimuli is not only restored, but even intensified. Phasic parabiotic changes of the pressor reflexes were not observed either at the beginning of the reduced arterial pressure nor during its restoration. The stimulation of the corresponding efferent nerve by impulses of different intensity demonstrated that the so-called “rule of force” remained undisturbed.
