Материалы и методы: проводилось гистологическое, иммуногистохимическое (с антителами к коллагену I, III типов, матричным металлопротеиназам MMP-1, MMP-9, ингибитору матричных металлопротеиназ TIMP-1, фибронектину; фибулину-5; коннексину-43), электронномикроскопическое и электронноиммуноцитохимическое исследование с морфометрией 15 фрагментов миометрия рожениц с СД со слабостью родовой деятельности (основная группа) и 10 - без СД (группа контроля). Результаты исследования: в миометрии при СД отмечается снижение экспрессии коннексина-43, фибулина-5, TIMP-1, коллагенов I и III типов с преобладанием коллагена III типа, а уровень экспрессии фибронектина и MMP1,9 не изменяется. Электронные микроскопия и иммуноцитохимия показали уменьшение количества межклеточных контактов и резкое снижение экспрессии коннексина-43 по сравнению с контролем. Выводы: комплекс найденных изменений миометрия у женщин при слабости родовой деятельности является проявлением СД.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to identify morphological features of the myometrium of the lower segment of the uterus during connective tissue dysplasia (CTD) in women with uterine inertia. Materials and methods: we conducted histological, immunohistochemical (antibodies to collagen I, III, matrix metalloproteinases MMP-1, MMP-9, inhibitor of matrix metalloproteinases TIMP-1, fibronectin; fibulin-5; connexin-43), electron microscopy and immunocytochemical study with morphometry of 15 fragments of the myometrium of pregnant women with diabetes with weakness of labor activity (the main group) and 10 without diabetes (control group). The results of the study: in the myometrium in CTD, there is a decrease in the expression of connexin-43, fibulin-5, TIMP-1, collagen I and III types with a predominance of type III collagen, and the expression level of fibronectin and MMP1,9 is not changed. Electron microscopy and immunocytochemistry have shown a decrease in the number of intercellular contacts and a sharp decrease in the expression of connexin-43 compared to control. Conclusions: the complex of the detected changes of the myometrium in women with uterine inertia is a manifestation of CTD.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>миометрий</kwd><kwd>соединительнотканная дисплазия</kwd><kwd>иммуногистохимическое исследование и электронная микроскопия/</kwd><kwd>myometrium</kwd><kwd>connective tissue dysplasia</kwd><kwd>immunohistochemistry and electron microscopy</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">Ralph M.
