[The effect of the stimulation and blockade of the beta-adrenoreceptors on the myoelectrical activity of the small intestine].
Functional significance of beta-adrenoreceptors located at cholinergic interneurons of myenteric plexus was confirmed for motor responses to exogenous and endogenous acetylcholine, serotonin, histamine and bradykinin. A specific mechanism of the activation of small intestine's contractile apparatus by sympathoadrenal system seems to exist in the organism.
