A study on the distribution of G-cells in human gastric mucosa

The distribution of G-cells in the gastric glands was studied quantitatively using the indirect immunoperoxidase method in 37 resected stomachs: 11 for esophageal cancer, 14 for gastric cancer, 4 for gastric ulcer, 7 for duodenal ulcer, and 1 for atypical epithelium. G-cells were seen in the pyloric glands and in the pseudopyloric glands in the atrophic fundic gland area. No G-cells were found in the fundic glands or in the cardiac glands. There was a significant correlation between the number of G-cells and the pyloric and/or pseudopyloric glandular tubes (p less than 0.01). The number of G-cells per glandular tube was 1.9 +/- 0.5 in the pyloric glands and 1.2 +/- 0.4 in the pseudopyloric glands on the pyloric part of the atrophic fundic gland area. G-cells were rarely seen in the pseudopyloric glands on the cardiac part of the atrophic fundic gland area. It is suggested that the pseudopyloric glands without G-cells in the cardiac region are akin to cardiac glands.
