[Topographic features of the ultrastructure of parietal cells of the gastric mucosa (morphometric study)].

A new methodical approach to the study of the ultrastructure of the parietal cells of the gastric mucosa is suggested. Electron microscopic study of peculiarities of the submicroscopic cell organization at the three main levels (the generative zone, the zone of the most active cells, and the gland floor) is necessarily followed by the morphometric analysis of the results obtained. Marked differences in the ultrastructural morphometric indices of the parietal cells located at various levels of the glands were demonstrated with the aid of the mentioned method. Despite certain difficulties, such approach can be also applied to the study of other cell elements of the gastric mucosa and also of many other tissues with continuous quick cell renewal.
