At the upper portion of the stomach, gastritis has been classified to some patterns by the congo-red method. In this paper, the congo-red method was examined in 44 cases of gastritis with ulcer in the upper portion of the stomach. On the other hand, the location and age distribution were examined by resected specemens in 62 cases of ulcer. The location of ulcers is most frequently (61%) on the posterior wall in the upper portion of the stomach. The cases above 60 year-old is seen in 47% of 106 patients. In these 44 cases, the congo.red pattern was classified into 5 types. Most cases showed type IV, according to the classification of S. Suzuki, M.D. But, the type IV should be devided into 2 sub-types; type IV-a, and IV-b. Discolored area of the type IV-a occupied the greater curvature from the fornix and the angulus, and the type IV-b occupied only the f ornix or no area. The type IV-a was recognized in 12 cases, and the type IV-b in 22 cases. As for congo-red pattern, discolored area is decreased following to the advancing age. The location and age distribution of ulcers in the upper portion of the stomach are closely related to the congored pattern. According to the age distribution of the congored pattern in relation with biopsy analysis, a bilateral expansion of gastritis may be considered as much as an unilateral expansion.
