Gastrin cell distribution in normal human stomachs and in patients with Zollinger-Ellison syndrome.
Quantitative distribution of gastrin cells was evaluated in three normal human stomachs and in four stomachs from patients with Zollinger-Ellison syndrome. Cells identified by the immunoperoxidase method were counted along the entire length of five mucosal strips parallel to the axis of the lesser curvature and sampled from the posterior to the anterior walls. The number of cells per unit area (2300 microns2) decreased from the pylorus to the borderline of the gastric body from (mean +/- SEM) 50.9 +/- 12.0 to 24.2 +/- 13.0 and from 29.6 +/- 5.6 to 10.4 +/- 2.6 for control and Zollinger-Ellison syndrome, respectively, with large interindividual variations. From factorial analysis no statistical difference was found between the two groups. It is therefore suggested that the number of gastrin cell in antral mucosa may not be a significant criteria in the diagnosis of Zollinger-Ellison syndrome.
