1. The role of epithelium in the non-adrenergic non-cholinergic (NANC) inhibitory response to electrical nerve stimulation as well as to the putative neurotransmitter, vasoactive intestinal polypeptide (VIP), was evaluated in guinea-pigs anaesthetized with chloralose-urethane. 2. The tracheal pouch, an in vivo method to demonstrate the NANC inhibitory response, was used in all experiments. The relaxation response was measured as a pressure drop (cm of H2O) in the pouch. The animals were given atropine (5 mg kg-1) and propranolol (1 mg kg-1) intraperitoneally to block adrenergic and cholinergic responses in the pouch...
