  • Title: Mechanisms of Discoordination of Contractile Activity in the Gastroduodenal Zone during Psychogenic Stress in Rabbits.
    Author: Ovsyannikov VI, Berezina TP, Shemerovskii KA.
    Journal: Bull Exp Biol Med; 2015 Aug; 159(4):446-9. PubMed ID: 26385409.
    Abstract:
    Inhibition of the contractile activity of the stomach induced by psychogenic stress persisted after blockade of muscarinic and nicotinic cholinergic receptors and α2 and β1/β2-adrenergic receptors. Stress-induced increase in contractile activity in the proximal part of the duodenum persisted during blockade of muscarinic and nicotinic cholinergic receptors, β1/β2-adrenergic receptors. At the same time, blockade of the above cholinergic and adrenergic receptors eliminated the stress-induced increase in contractive activity in the distal part of the duodenum.
