The preoperative gastrocamera findings of atrophic pattern are compared with the histological findings of glandular atrophy in the resected stomachs including 27 cases of primary chronic gastrtis, 14 cases of gastric ulcer, 2 cases of gas-troduodenal ulcer, 15 cases of duodenal ulcer, one of gastric polyp and 6 cases of gastric cancer. The submucosal vessel visualization and the dis-coloration of the mucosa shown by the gastro-camera coincide well with the histological glandular atrophy in the f undic area. These atrophic patterns, however, are less frequently seen in the antrum where histological examination reveals atrophic or atrophic hyperplastic change more or less almost in all the cases. In endoscopic interpretaion of the antrum, the irregular granular pattern of the mucosa is found to be an important sign of atrophic or atrophic hyperplastic change besides mucosal discoloration and the vessel visalization. Absorption photometries of the fresh gastric mucosae which are taken from the other 38 speci-mens show the mucosal optical density depend mainly upon the population of chief cells as well as on the thickness of the mucosa. The animal experiment (made on 8 dogs) reveals that the paradoxical finding of poorer vessel visu-alisation in the antrum, where chief cells as opaque element are absent and higher mucosal trans-lucency is observed, can be mostly explained by lower distensibility of the stonach wall in the antrum than in the corpus.
