title: Cytochrome oxidase activity in the gastric mucosa of patients with iron deficiency.
abstract: Cytochrome oxidase activity was assessed histochemically in gastric biopsies taken from 22 iron-deficient patients. Activity was strong only in parietal cells, and the total amount of activity appeared to be proportional to the number of parietal cells present in the sections. No evidence was found of diminished activity within parietal cells.
