[Effect of certain neuromediators on segmental mechanisms of vasomotor regulation].
Effect of m-cholinergic and alpha-adrenomimetic compounds on the systems of activation and reduction of spinal vasomotor neurones was studied in experiments on spinal curarized cats. It was shown that stimulation of m-cholino- and alpha-adrenoreceptors of the segmental structures produces an inhibition of the neurogenic vascular tone. However, cholino- and adrenomimetic drugs influence the different systems participating in the circulatory neurogenic regulation.
