HISTOPATHOLOGICAL STUDY ON THE PROGRESS OF CHRONIC GASTRITIS WITH SPECIAL REFERENCE TO AGE

Abstract

The author collected f ourty three specimens of the stomach in the younger age from necropsy which died by other diesease than of the stomach. He investigated the frequencies of the following histological features in the mucous membrane as a) fibrosis, b) round cell infiltration, c) lymphatic fallicles d) intestinal epithelial metaplasia and e) erosive depression to compaire them with age. He has found that the features as a), d) and e) increase steadly with age, b) increases till five five years of age and thereafter becomes constant. The feature c) makes a special curve increasing to fifteen years of age and then decreases abruptly to 20 years without any flactuation in f urthor course. The frequency of those features differs markedly between the normal necropsied stomach and surgically resected stomach with chronic gastritis in the 3rd decade, but is nearly the same in 6th decade. Then it was concluded that the influence of the age must be highly estimated in the histological investigation of the stomach with chronic gastritis.
