  • Title: [Effects of somatostatin and its analog on gastric secretion. An application of the secretagogues to gastric secretion].
    Author: Nomura M, Nishimori T.
    Journal: Nihon Yakurigaku Zasshi; 1985 Sep; 86(3):189-95. PubMed ID: 2867956.
    Abstract:
    A simple technique to examine the effects of drugs on the gastric secretion response to the secretagogues without anesthesia was shown in this paper. The administration of bethanechol (1 mg/kg, s.c.), histamine (15 mg/kg, s.c.) or pentagastrin (0.25 mg/kg, i.p.) significantly increased the gastric volume and the total acid output in the pylorus-ligated rat. These responses to the secretagogues were inhibited by N-butylscopolamine, urogastrone or cimetidine dose-dependently. N-butylscopolamine (0.5 mg/kg, i.p.) inhibited the response to bethanechol but not that to pentagastrin or histamine. Cimetidine (5 mg/kg, i.p.) inhibited not only the response to histamine but also the acid response to bethanechol or pentagastrin. Urogastrone (5 mg/kg, i.p.) inhibited the response to these three secretagogues. The ratio of the total acid output to the gastric volume was also examined in each of the cases. Somatostatin (0.1 mg/kg, i.p.) inhibited the response to pentagastrin, but not that to bethanechol or histamine. On the other hand, an analogue of somatostatin (SS-1; 0.1 mg/kg, i.p.) inhibited the response to bethanechol but not that to pentagastrin or histamine.
