title: Protection against duodenal ulceration by somatostatins.
abstract: The purpose of our investigation was to study the effect of two somatostatin analogs (SMS 201-995 and 008) on duodenal ulcer disease induced by cysteamine in rats. Male Wistar rats were given cysteamine (28 mg/100 g body wt.) by rubber stomach tube three times in a single day. All animals of the test group were injected subcutaneously either with SMS 201-995 in different doses or with 008. On the 3rd day stomach, duodenum, and adrenal glands were macroscopically examined for lesions (duodenal ulceration, gastrointestinal bleeding, adrenal hemorrhage). Our results showed a dose-dependent effect of SMS 201-995 on the mortality, incidence, and intensity of cysteamine-induced duodenal lesions in rats. The incidence and the intensity of gastrointestinal bleeding and adrenal hemorrhage were also dose-dependently reduced by SMS 201-995. There was no definite effect of 008 on the mortality, incidence, or intensity of cysteamine-induced duodenal ulceration.
