[The role of the beta-adrenoreceptors in the manifestation of the peristaltic reflex].
Distension of the ileal segment was shown to induce its contraction in isolated portion of the cat ileum, the response being abolished by M-cholinergic blockade and preserved after N-cholinergic blockade. Blockade of the beta-adrenoreceptors or their stimulation did not affect the peristaltic reflex. The findings suggest that the excitatory beta-adrenoreceptors are not directly involved in the first phase of peristaltic reflex.
