RESUMO
Production of hydroxyl anions by tissue samples of pylorus mucous membrane obtained from 45 patients with gastric or duodenal ulcers was investigated. The production was estimated using the recently developed method based on measurement of rate of pH change in urea-containing reaction mixture. The rate of [OH-] generation as a result of H. pylori metabolism accounted on pylorus square varied from 0.4 to 1318.9 mcmol [OH-]/min, and in 90.2% of cases it did not exceed 128.1 mcmol [OH-]/min. This rate is comparable to mean rate of [H+] generation in stomach of healthy man--114.2-238.4 mcmol [H+]/min. Obtained results allow to conclude that this bacterium may participate in regulation of stomach acid-base balance.
