1. The 5-HT4 receptor has only recently been identified but has yet to be cloned. This paper describes the pharmacology of a potent and selective 5-HT4 receptor antagonist, GR113808, which will be useful in the further characterization of this recept

1. The receptors that mediate stimulation of anion secretion by prostanoids in isolated preparations of guinea-pig gastric and ileal mucosa have been compared by use of selective prostanoid agonists and antagonists. 2. In gastric mucosa, the relative

1. The pharmacological characterization of the 5-HT3 receptors in guinea-pig isolated tissues is described. The tissues used were ileum (longitudinal muscle-myenteric plexus), colon and vagus nerve. The guinea-pig isolated colon is a novel preparatio

5-Hydroxytryptamine (5-HT) induced concentration-related relaxations (EC50 = 9·1 μm) of guinea-pig proximal colon pretreated with ketanserin (1 μm) and ondansetron (10 μm). This 5-HT-induced effect was neuronally mediated since it was blocked by

Gastric mucosal lesions were produced in rats by dosing orally with aspirin, 300 mg/kg. Predosing orally with either ranitidine or cimetidine inhibited this lesion formation; the respective ED50 values were 0.8 and 3.9 mg/kg p.o. Oral ranitidine also

1 The effect of chlorpromazine (Cpz) on the net fluxes of water and sodium in the ileum and colon has been studied in the anaesthetized rat. 2 Under control conditions both the ileum and colon absorbed water and sodium. Cpz (100 mumol/kg, s.c.) had n

The H2-receptor antagonists ranitidine and cimetidine were tested against gastric secretory dose-response curves to histamine, pentagastrin and bethanechol in the Heidenhain-pouch dog. Histamine-induced gastric secretion was antagonized in a competit

1. An isolated whole stomach preparation from immature rats is described. The lumen of the stomach was perfused and the hydrogen ion activity of the perfusate recorded continuously. 2. The mean basal acid secretion before stimulation was 4-19 +/- 0-3
