Effect of bombesin on extragastric gastrin in man. 1975

N Basso, and E Lezoche, and A Materia, and S Giri, and V Speranza

The effect of a protein test meal and a bombesin infusion on extragastric gastrin levels was studied in patients with truncal vagotomy, antrectomy, and gastroduodenostomy or gastrojejunostomy and in patients with total gastrectomy. In patients with vagotomy, antrectomy, and gastroduodenostomy and in patients with total gastrectomy the gastrin levels were raised by 33% and 35%, respectively, from basal after test meal, while during BBS infusion gastrin values decreased by 25% and 30%, respectively, from basal. In patients with vagotomy, antrectomy, and gastrojejunostomy, test meal and BBS infusion did not significantly alter basal gastrin values. It is concluded that BBS does not stimulate extragastric gastrin.

D010455 Peptides Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS. Peptide,Polypeptide,Polypeptides
