[Effect of emotional-pain stress on the adrenocholinoreactivity of the smooth muscle of the portal vein].
Effect of emotional painful stress (EPS) on adreno- and cholinoreactivity of the portal vein was studied. EPS produced a significant decrease in adrenoceptor sensitivity of the vein to noradrenaline, which was not accompanied by a significant change of cholinoceptor sensitivity to acetylcholine. A possible mechanism of the phenomenon is discussed.
