[Effects of pentagastrin and somatostatin on duodenal motility in chronic experiments].
Electromyography of the duodenums was performed in dogs, using two bipolar electrodes placed 5 and 10 cm aborally of the pylorus on the serosa of the duodenums. 10 days after implantation and 24 hours after the last meal the duodenal motility was registered in 9 bastard dogs for 5 hours. Pentagastrin, given as a 1-hour intravenous infusion, changed the interdigestive motility to an irregular (postprandial) pattern, which continued up to the end of measurement or was followed by a prolonged phase III with return to cyclic activity. Infusion of somatostatin for 1 hour interrupted the interdigestive motility leading to a prolonged phase I pattern and to partial discoordination. After the end of infusion phase III motility returning to cyclic activity or irregular activity were registered. A standard relaparotomy 10 days after implantation was performed in 3 dogs. Up to the second day of the postoperative period interdigestive cycles of duodenal motility were not obtained.
