[The cholinergic mechanisms of the excitatory effects from stimulation of the beta-adrenoreceptors in the pyloric sphincter and small intestine].
1993
: Jb been shown that beta-adrenergic stimulation by isadrine can lead to decreasing as well increasing of spre activity of the pyloric sphincter and small intestine administration of isadrine in conditions of the blockade of M- and N-cholinoreceptors suppressed the spike activity in all the portions of the intestine. The data obtained suggest that excitatory beta-adrenoreceptors are located on the cholinergic interneurons of the enteral nervous system. The suppression of the spike activity was, evidently, due to a stimulation of postsynaptic beta-adrenoreceptors.
