title: [Catecholamine absorption by stomach tissues in normal conditions and in experimental ulcer].
abstract: Different topographic zones of the stomach and the duodenum differ in the intensity of accumulation of exogenous adrenaline (A) and noradrenaline (NA). NA is markedly absorbed by the tissues of the greater and lesser curvatures of the stomach and is absorbed less intensely by the pylorus and duodenum. As regards A an opposite picture is observed. Experimental neurogenic ulcer is followed by decreased accumulation of exogenous NA coupled with intensification of A deposition in the tissues of individual topographic zones of the stomach. The peripheral N-cholinoblocker quateron promotes the rise of exogenous NA reservation in the tissues of the stomach and duodenum.
