title: [Ultrastructure of parietal cells in summer and in the period of hibernation].
abstract: The parietal cells of active and hibernating citellus erythkogenus Br. were studied by electron microscopy and morphometric analysis. It was shown that there are clear-cut changes in the ultrastructure of parietal cells during hibernation, which reflect the absence of secretory activity of the cells. No pronounced dystrophic changes in morphology of the parietal cells were found. Structural differences due to the life stages of the cells were preserved.
