Ablation of the myenteric plexus impairs alpha but not beta adrenergic receptor-mediated mechanical responses of rat jejunal longitudinal muscle.


The mechanical responses produced by alpha and beta adrenergic receptor agonists were evaluated in control and myenteric neuron-ablated rat jejunal longitudinal muscle. The myenteric plexus of the jejunum was destroyed by serosal application of benzalkonium chloride (BAC). The beta adrenergic receptor agonists isoproterenol and sulfonterol produced a… (More)
