title: [Dynamics of endogenous bacterial nitrite formation in the stomach. 5. Dependence of the nitrate concentration on the pH value of the stomach secretion].
abstract: The content of nitrate and nitrite was examined in the fasting gastric juice samples of 54 anamnestically healthy, young voluntary test-persons after at least 12 h of food abstinence. The analysis was made separately each time for the proper watery gastric juice as well as for the gastric mucus. It could be shown that significant differences exist between the concentration of nitrate and nitrite in the juice and the gastric mucus, that there is a pH-dependence in the concentration of nitrate in the juice and that the already earlier described gastric source of nitrate by the enrichment of nitrate ions in the juice producing glands of the gastric lining can be confirmed here too.
