Accepted for publication 9 November 1995 Abstract Background-Patients with duodenal ulcer (DU) have high basal (BAO) and peak (PAO) acid outputs. The effect of Helicobacter pylori eradication on these variables is unclear. Aim-To discover if gastric acid hypersecretion in patients with DU is caused by Hpylori. Patients and methods-BAO, gastrin releasing peptide (GRP), and pentagastrin stimulate...

We studied acid secretory responses to exogenous pentagastrin and to exogenous and endogenous gastrin in 12 stable cirrhotic subjects with portacaval shunt, 12 unshunted cirrhotics, and 12 normal subjects. Basal and stimulated serum gastrin concentrations as well as basal and maximum acid outputs were similar in the three groups. At low doses of either exogenous pentagastrin or gastrin-17 (G17)...

The inhibitory effect of intravenous secretin and intrajejunal acid infusion on basal and pentagastrin-induced gastric acid secretion as well as the stimulatory influence of both infusions on pancreatic flow rate and bicarbonate output were compared in two groups of healthy subjects. Secretin strongly inhibited basal acid output and slightly decreased pentagastrin induced gastric secretion. Int...

An indicator fractionation technique using radioactive rubidium has been used to measure pancreatic blood flow after infusions of secretin, pancreozymin, urecholine, and pentagastrin. Secretin resulted in the production of a large volume of low viscous pancreatic juice and was associated with an increase in the cardiac output. Duodenal and pancreatic blood flow and perfusion rate were increased...

Antisecretory effect of single oral therapeutic doses of pirenzepine (25 mg and 50 mg) and cimetidine (200 mg and 400 mg) was studied in 12 patients with duodenal ulcer. Gastric secretion was studied in basal condition and after stimulation with pentagastrin. Basal, maximum and peak acid output, basal and maximum acidity, and basal and maximum volume were calculated after computerised correctio...

Caerulein, gastrin and pentagastrin stimulation of the Na+/H+ exchange leads to intracellular alkalinisation in pancreatic acinar cells. Activation of protein kinase-C is the more probable mechanism involved in the effect of caerulein.

A case of a 69 year old man in whom hypertrophic gastritis was associated with the carcinoid syndrome is reported. Concentrations of prostaglandin E2 were increased in plasma, gastric juice, gastric mucosa and urine. He had marked hypochlorhydria in response to pentagastrin stimulation (Peak acid output (PAO) pg:0.2 mmol/h). After successful hepatic arterial embolisation of the metastases (as i...

The effect of acute oral administration of three different doses (4, 8, and 16 mg) of loperamide, a peripheral opiate agonist, on basal and submaximal pentagastrin-stimulated gastric acid secretion was evaluated in healthy volunteers. Both basal and stimulated gastric secretion were significantly lowered by 8 and 16 mg of the drug in comparison with a control study, while 4 mg was ineffective. ...

noise is considered as one of the most severe sources of environmental and workplace constraints. many noise effects are well known on immune function, hormonal levels, cardiovascular and respiratory systems. in this study, our aim is to evaluate the effects of traffic noise exposure on basal and stimulated gastric pepsin secretion. 48 male rats were exposed to traffic noise (86 db) for a short...

The effect of endogenous pancreatic glucagon on submaximal pentagastrin stimulated gastric acid secretion was studied by infusion of 1-arginine in patients with duodenal ulcer before and after parietal cell vagotomy without drainage (PCV). Preoperatively infusion of 1-arginine resulted in a marked inhibition of acid secretion, whereas no effect was found postoperatively. Plasma glucagon concent...
