Dogs exposed to 8 Gy 60Co gamma mid-abdominal irradiation exhibited emesis with an average latency of 102 min and an average of 7.4 episodes over 96 min. There were no significant changes in dogs subjected to a chronic bilateral subdiaphragmatic vagotomy, but emesis was prevented by ablation of the area postrema. Indomethacin pretreatment also prevented radiation-induced emesis in two of seven dogs and in the remainder reduced the average number of episodes. Domperidone pretreatment prevented radiation-induced emesis in all of four dogs tested. In electrophysiological studies recording from the area postrema the chemosensitive neurons were found to be normally silent in anesthetized preparations but excitable by a variety of emetic agents. After irradiation of the abdomen spontaneously active neurons were found with a discharge pattern that mirrored the behavioral pattern of postirradiation emesis. These studies are consistent with radiation-induced emesis being humorally mediated in the dog and implicate dopamine and/or prostaglandins as possible mediators.
