Abstract

By immunohistochemistry the three neuropeptides enkephalin (ENK), substance P (SP) and vasoactive intestinal polypeptide (VIP) were all localized to numerous nerve fibres in the circular smooth muscle layer and the myenteric plexus of the feline pylorus (1, 3). After pretreatment with vinblastine to block intraaxonal transport of transmitter peptides within neurons ENK and VIP immunoreactive nerve cell bodies could be demonstrated in the myenteric plexus of the pylorus. Immunohistochemical studies of the thoracic and abdominal vagal nerve trunks in man and cat have also demonstrated the presence of various peptides within nerve fibres (4). This study was undertaken to study the effects of the three peptides on the motor activity of the pyloric sphincter of the cat in vivo. The effects of pharmacological blocking agents on these motor responses and on the motor responses obtained at electrical efferent vagal nerve stimulation were also investigated.
