title: [Functional morphology of the parietal cells].
abstract: Perfused stomachs of anesthetized Citellius erythrogenys Br. were monitored for acid secretion, fixed at certain periods of secretory activity and examined by electron microscopy. Two kinds of secretory responses to identical doses of histamine were observed: with the abrupt and the slow decrease of HCl output. The characteristic morphology of active and non-secreting parietal cells was confirmed, and some intermediate stages were studied. In case of the abrupt decrease of HCl secretion endocytotic membrane profiles were described.
