Effects of motilin on gastric and pancreatic secretion in dogs

Scandinavian Journal of Gastroenterology. Supplement

Abstract

13-norleucine motilin (13-nle-motilin), a synthetic analogue of motilin, infused intravenously in graded doses (range: 1.5 to 100 mug/kg-h) produced a dose-dependent increase in basal gastric acid and pepsin secretion and in pancreatic bicarbonate and protein secretion in conscious dogs provided with gastric and pancreatic fistula and Heidenhain pouches. When infused in a constant dose against a background stimulation with pentagastrin, histamine or a peptone meal, 13-nle-motilin inhibited both acid and pepsin secretion from the main stomach and the Heidenhain pouch. It also inhibited dose-dependently secretin-induced pancreatic bicarbonate secretion. Since motilin is released by duodenal acidification, it may be involved in the feedback mechanism controlling gastric and pancreatic secretion.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
