Effect of a sulphated glycopeptide on rat gastric acid secretion stimulated by histamine, bethanechol, pentagastrin and dibutyryl cyclic AMP

The antisecretory activity of a semisynthetic sulphated glycopeptide (GLPS) was studied in rats in which the secretion rates of gastric acid were detennined on the perfused stomach preparation. GLPS at 1 mg/kg i.v. reduced the hypersecretory effect of dibutyryl cyclic AMP, histamine, pentagastrin, bethanechol but not of theophylline.
