Целью исследования явилось изучение морфогенеза гранулематозного воспаления в печени у новорожденных животных и в отдаленные периоды жизни.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Эксперимент проводился на 70 новорожденных мышах линии C57BL/6, разделённых две группы. Мышам 1-й (опытной) группы на первые сутки с момента рождения интраперитонеально вводили раствор вакцины БЦЖ в дозе 0,02 мг/кг. Мышам 2-й (контрольной) группы на первые сутки начала эксперимента интраперитонеально вводили 0,02 мл физиологического раствора. Образцы печени подвергали морфологическому и морфометрическому изучению: подсчитывали массу тела мышей (г), объёмную плотность (Vv) дистрофии и некрозов гепатоцитов, очагов экстрамедуллярного кроветворения, численную плотность (Nai) двуядерных гепатоцитов, фигур митозов, диаметр гранулем (мкм), и численную плотность (Nai) гранулем в тестовой площади</p></sec><sec><title>Результаты</title><p>Результаты. Введение вакцины БЦЖ новорожденным мышам на 1-е сутки привело к отставанию в их развитии и дефициту массы тела вплоть до 28 суток жизни. При введении вакцины БЦЖ новорожденным мышам линии C57B1/6 отмечается отсроченное формирование гранулём, начиная с 10 суток после введения вакцины БЦЖ, и последующее увеличение к 56 суткам как количества, так и размеров гранулём. Очаги экстрамедуллярного кроветворения в печени мышей после введения вакцины БЦЖ сохраняются более длительно (вплоть до 28 суток), что связано, вероятно, с участием клеток очагов кроветворения в воспалительном процессе в паренхиме печени. При введении вакцины БЦЖ отмечаются выраженные деструктивные изменения гепатоцитов у мышей во все возрастные периоды при сниженных показателях репаративной регенерации печени.</p></sec><sec><title>Заключение</title><p>Заключение. Введение вакцины БЦЖ новорожденным мышам приводило к образованию туберкулезных гранулем в печени во взрослый период жизни с развитием деструктивных изменений гепатоцитов и сниженной репаративной способностью печени.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. The aim of the study was to study the morphogenesis of granulomatous inflammation in the liver in newborn animals and in remote periods of life.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The experiment was carried out on 70 newborn C57BL / 6 mice, divided into two groups. On the first day after birth, mice of the 1st (experimental) group were injected intraperitoneally with a solution of the BCG vaccine at a dose of 0.02 mg / kg. On the fi rst day of the beginning of the experiment, the mice of the 2nd (control) group were injected intraperitoneally with 0.02 ml of physiological solution. Liver samples were subjected to morphological and morphometric study: the body weight of mice (g), the volumetric density (Vv) of dystrophy and necrosis of hepatocytes, foci of extramedullary hematopoiesis, the number density (Nai) of binuclear hepatocytes, mitotic figures, the diameter of granulomas (μm), and the number density were calculated (Nai) granulomas in test area.</p></sec><sec><title>Results</title><p>Results. The introduction of the BCG vaccine to newborn mice on the 1st day led to a delay in their development and a lack of body weight. With the introduction of the BCG vaccine to newborn mice of the C57B1 / 6 line, a delayed formation of granulomas is noted, starting from the 10th day after the administration of the BCG vaccine, and a subsequent increase by 56 days in both the number and size of granulomas. The foci of extramedullary hematopoiesis in the liver of mice after the administration of the BCG vaccine persist for a longer period (up to 28 days), which is probably due to the participation of cells of the foci of hematopoiesis in the inflammatory process in the liver parenchyma. With the introduction of the BCG vaccine, pronounced destructive changes in hepatocytes in mice at all age periods are noted with reduced rates of reparative liver regeneration. Conclusion. The introduction of BCG vaccine to newborn mice led to the formation of tuberculous granulomas in the liver during the adult period of life with the development of destructive changes in hepatocytes and a reduced reparative ability of the liver.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>туберкулезные гранулемы</kwd><kwd>печень</kwd><kwd>морфогенез</kwd><kwd>новорожденные</kwd><kwd>возрастная динамика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tuberculous granulomas</kwd><kwd>liver</kwd><kwd>morphogenesis</kwd><kwd>newborn</kwd><kwd>age dynamics</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">Шкурупий В.
