Для морфометрической оценки ламеллярных телец производили подсчет количества гранул Одланда в зернистом слое в расчете на 100 мкм2. С помощью прикладной программы ImageScopeM определяли средний и эквивалентный диаметры ламеллярных телец (мкм), а также их периметр (мкм); среднюю площадь одного сечения ламеллярного тела (мкм2); коэффициент округлости и среднюю относительную электронную плотность ламеллярных телец.</p><p>Электронномикроскопический анализ показал значительные изменения в ультраструктуре кератиноцитов, обусловленные влиянием десинхроноза. Максимальные трансформации наблюдались в гранулах Одланда (ламеллярных тельцах). Морфометрическая оценка позволила выявить изменения в количестве структур (увеличение), их размере (уменьшение), а также в распределении в них ламеллярных пластинок.</p><p>При десинхронозе наблюдались многочисленные изменения в ультраструктуре кератиноцитов, что в свою очередь может свидетельствовать о существенных системных нарушениях в эпидермисе в целом. При этом трансформации затрагивали преимущественно клетки шиповатого и зернистого слоев, в частности ламеллярные тельца.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study is to study the effect of dark deprivation on the ultrastructure of epidermal keratinocytes. Electron microscopic evaluation of the status of keratinocytes of the epidermis of the skin of white outbred rats with dark deprivation. For morphometric evaluation of the production capacity of counting the number of granules per 100 μm2. Using the application program ImageScopeM determines the average and equivalent indicators of lamellar bodies (μm), as well as their perimeter (μm); the average area of one section of the lalellar body (μm2); roundness coefficient and average relative electronic number of lamellar bodies.</p><p>Electron microscopic analysis of keratinocytes revealed significant changes in their ultrastructure, which are due to the influence of desynchronosis. Maximum transformations were observed in Odland granules (lamellar bodies). Thus, the morphometric assessment revealed changes in the number (increase), their size (decrease), as well as in the distribution of lamellar plaques in them.</p><p>With desynchronosis, significant changes in the ultrastructure of keratinocytes are observed. This indicates significant systemic disorders of the epidermis as a whole. In this transformation, there are cells of a special prickly and granular layer, in particular, lamellar bodies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>темновая депривация</kwd><kwd>кератиноцит</kwd><kwd>эпидермис</kwd><kwd>кожа</kwd><kwd>гранулы Одланда</kwd><kwd>ламеллярные тельца</kwd><kwd>липиды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dark deprivation</kwd><kwd>keratinocyte</kwd><kwd>epidermis</kwd><kwd>skin</kwd><kwd>Odland granules</kwd><kwd>lamellar bodies</kwd><kwd>lipids</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Надольник, Л.
