To clarify the protein metabolism in peptic ulcer disease, the amino acid content was determined in gastric juice of gastric ulcer patients (n = 30), duodenal ulcer patients (n = 16), gastroduodenal ulcer patients (n = 8), and hospital controls (n = 8). The amino acid output in the gastric ulcer group was greater than that of the hospital control both in basal and maximal secretion. In the duodenal ulcer group of patients who were high secretors of gastric juice, the amino acid concentration was low, so the amino acid output was also lower than that of the hospital control group. Tetragastrin did not increase the amino acid output in the gastric juice. The amino acid amount may be decided also by the architecture of the gastric mucosa and not only by the ulcer lesion itself. The protein loss from gastric mucosa may well result in hypoproteinemia in peptic ulcer disease of the stomach.

The effects of various antiulcer drugs and hormones on the cell kinetics of the mouse gastric mucosa were studied using an autoradiographic technique with 3H-thymidine. The drugs or hormones were administered orally or parenterally once or twice a day for 7 consecutive days, and 3H-thymidine was injected after the last administration of the drug. The autoradiograph was prepared and then the labeling index was counted. Cimetidine (100 mg/kg X 2/day, p.o.), geranylgeranylacetone (GGA, 100 mg/kg X 2/day, p.o.) and Cu-chlorophyllin-Na (300 mg/kg X 2/day, p.o.) did not show any effect on the labeling indices in both the tissues of the fundic and pyloric glands, while carbenoxolone (100 mg/kg X 2/day), p.o.) reduced the labeling index in the pyloric glands. Tetragastrin (1 mg/kg X 1/day, i.m.) increased the labeling index in the fundic glands, whereas secretin did not affect it. Hydrocortisone (100 mg/kg X 1/day, S.C.) reduced the labeling index in the fundic glands, and this reducing effect was prevented by combining hydrocortisone with GGA. From these results, it was indicated that the labeling index in the normal mouse gastric generative zone was no influenced by the tested antiulcer drugs, except carbenoxolone; but the index was influenced by tetragastrin and hydrocortisone, especially in the fundic glands. It was also suggested that the changes in the cell kinetics of the gastric mucosa could be related to the etiology of gastric ulcer since there was a possibility that geranylgeranylacetone could control the action of hydrocortisone, an ulcerogenic agent, on the gastric mucosal cell-cycle.
