[Dynamics of endogenous bacterial nitrite formation in the stomach. 6. Redox potential and nitrite formation in stomach secretions].
The redox potential depending on the pH-value and the concentration of nitrite was examined in the fasting gastric juice samples of 132 anamnestically healthy, young, voluntary test-persons. It turned out that small pH-values (acid) are associated with high redox potentials and big pH-values (neutral) with smaller redox potentials. Therefore the hydrogen ion pressure (rH-value) resulting from these two quantities generally is situated in the indifferent range. Reducing properties of the whole juice can only occasionally be found, and apparently only then, if a neutral juice is acidified. Oxidizing properties have to be classified as exceptional cases. It cannot absolutely be traced on behalf of the findings, that can be raised with natural juices, if and when answered affirmatively, which effects the redox potential has on the formation of bacterial nitrite.
