Relation of the acid concentration of the parietal component of the gastric juice to the maximal acid output in man.
In two populations of patients tested with S.C. histamine and with I.V. pentagastrin the values of the theoretical acid [H+]O and chloride [Cl-]O concentration of the parietal secretion for a zero value of sodium from the relationships H+ = f ([Na+]) and Cl- = f ([Na+]) were calculated. In both populations a decrease of [H+]O and [Cl-]o for low acid outputs was observed. The parallel decrease of the calculated H+ and Cl- ion concentration of the parietal component for low acid outputs gives indirect evidence that parietal secretion could become hypotonic in patients whose acid output is low.
