Many clinicians have believed that H2-blockers and proton pump inhibitors ameliorate gastric ulcers via their antacid function. We examined the effects of these antacids on granulocytes. Gastric ulcer patients were administered an H2-blocker or proton pump inhibitor for a week and the number of granulocytes and the superoxide production were examined. To determine the trafficking of granulocytes, mice were exposed to restraint stress for 24 hr. The H2-blocker decreased the number of granulocytes, while the proton pump inhibitor suppressed their superoxide production in humans and mice. The major function of H2-blockers and proton pump inhibitors in curing gastric ulcers seems to be their suppressive effects on granulocytes. In this case, stress accelerates the trafficking of granulocytes from the bone marrow to the gastric mucosa. If we demonstrate a role for granulocytes in gastric ulcer formation, an gap in the acid–pepsin theory and theHelicobacter pyloritheory is filled in.
