Effect of Helicobacter pylori infection on antral gastrin and somatostatin cells and on serum gastrin concentrations
OBJECTIVES Helicobacter pylori infection induces selective reduction of the number of antral D-cells and results in abnormal regulation of serum gastrin secretion. The purpose of this study was to investigate the relationship between H. pylori infection and the numbers of G-cells and D-cells. METHODS The numbers of antral G-cells and D-cells, the ratio of G-cells to D-cells and fasting serum ...
متن کاملRelationship between gastrin cell number, serum, antral mucosa and luminal gastrin concentration and gastric acidity in antral atrophic gastritis.
The aim of our study was to investigate the relationship between gastrin producing cell density with antral mucosa, luminal and serum gastrin concentration in antral atrophic gastritis. Our study group consisted of 17 patients: six with mild atrophic gastritis, seven with moderate atrophic gastritis and four with severe atrophic gastritis. None of the patients had type-A atrophic gastritis but ...
متن کاملPositive correlation between symptoms and circulating motilin, pancreatic polypeptide and gastrin concentrations in functional bowel disorders.
Motilin, pancreatic polypeptide and gastrin blood concentrations in response to drinking water have been studied in 40 patients with functional bowel disease and compared with results in two groups of healthy control subjects. Patients with slow transit constipation and idiopathic megacolon showed impaired motilin release. Pancreatic polypeptide release was reduced in patients with slow transit...
متن کاملSerum gastrin in duodenal ulcer
Following truncal vagotomy and anterior pylorectomy for duodenal ulcer, fasting serum gastrin levels were higher at 84 ± 7.9 pg per ml than in unoperated patients with duodenal ulcer (16 ± 1.5 pg per ml). In response to a standard protein meal, the peak serum gastrin achieved in the vagotomized group was 259 ± 37.8 pg per ml at 75 minutes after ingestion, a much higher response than that obtain...
متن کاملGastrin cells and fasting serum gastrin levels in duodenal ulcer patients
The number of gastrin-producing cells in biopsy specimens from the gastric and duodenal mucosae in 19 duodenal ulcer patients was quantitated using a morphometric method. The level of immunoreactive gastrin in a sample of fasting serum obtained at the time of the biopsy was measured by radioimmunoassay. The results show no significant difference when compared with those from a group of normal c...
