title: [Gastric mucosal changes induced by the augmented Histalog test: endoscopic and histopathological study].
abstract: A prospective study of the effects of maximal doses of betazol hydrochloride ( Histalog ) on the endoscopic and histologic findings of the gastric mucosa of volunteers was made. Of the 11 patients examined, no alteration was seen on gastroscopic examination after Histalog in three, slight to moderate congestion of the mucosa in six and scattered oozing bleeding points in two. The study of the histologic findings revealed no statistical significant difference in the recurrence of erosion, hemorrhage and edema in the antrum and body gastric mucosa, before and after the administration of Histalog . It was concluded that maximal doses of Histalog cause no significant hemorrhage in the mucosa of the stomach and that the brown colour frequently seen in the gastric secretions of the final portions of a Histalog test is to be attributed to trauma to the mucosa by the nasogastric tube and to Histalog induced congestion of the mucosa.
