Материалы и методы. В качестве объекта для моделирования цирроза печени использовались белые крысы-самцы линии Wistar (n=30). Моделирование проводили по разработанной токсико-алиментарной методике (экспериментальная группа, n=15) и путем введения тетрахлорметана (контрольная группа, n=15). Животных выводили в разные сроки (через 8, 12 недель от начала моделирования и через 3 месяца после прекращения моделирования) и изучали морфологическую морфометрическую картину печени. Результаты . Разработанная токсико-алиментарная модель поражения печени приводит к развитию цирроза печени через 8 недель от начала моделирования (воспроизводимость - 93,3 %). При использовании тетрахлорметановой модели воспроизводимость цирроза печени через 8 недель составляет 26,7%, что подтверждается статистически меньшей толщиной соединительнотканных септ в контрольной группе по сравнению с экспериментальной (p=0,016, критерий Манна-Уитни).Разработанная модель обеспечивает сокращение времени моделирования (с 12 недель в контрольной группе до 8 недель в экспериментальной) цирроза печени, а также меньшую обратимость признаков цирроза печени через 3 месяца по сравнению с тетрахлорметановой моделью цирроза печени. Заключение. Разработанная токсико-алиментарная модель поражения печени приводит к развитию цирроза печени через 8 недель от начала моделирования. Разработанная модель обеспечивает сокращение времени моделирования цирроза печени, повышение воспроизводимости, а также меньшую обратимость признаков цирроза печени через 3 месяца по сравнению с тетрахлорметановой моделью цирроза печени.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to design an experimental model of liver cirrhosis in rats and to compare it with the carbon tetrachloride model of liver injury. Material and methods. White Wistar rats (n=30) were used as objects for modeling of toxic liver injury. The modeling was performed by the designed toxic-alimentary method (experimental group, n=15) and by means of the carbon tetrachloride injection (control group, n=15). The animals were sacrificed at different terms (8, 12 weeks after start of the modeling and 3 months after termination of the modeling), and the morphological and morphometric state of the liver was studied. Results. The designed toxic-alimentary model of liver injury leads to liver cirrhosis 8 weeks after start of the modeling (reproducibility - 93.3 %). The reproducibility of liver cirrhosis in case of using the carbon tetrachloride model 8 weeks after start of the modeling is 26.7%, which is proved by statistically lower thickness of connective-tissue septa in the liver in the control group in comparison with the experimental group (p=0.016, Mann Whitney U test). The designed toxic-alimentary method ensures shorter timing of the modeling of liver cirrhosis (from 12 weeks in the control group to 8 weeks in the experimental group) and also lower reversibility of liver fibrosis signs 3 months after termination of the modeling in comparison with the carbon tetrachloride model of liver injury. Conclusions. The designed toxic-alimentary model of liver injury leads to liver cirrhosis 8 weeks after start of the modeling. The developed model ensures shorter timing of the modeling of liver cirrhosis, increased reproducibility as well as lower reversibility of liver fibrosis signs 3 months after termination of the modeling in comparison with the carbon tetrachloride model of liver injury.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цирроз печени</kwd><kwd>экспериментальная модель</kwd><kwd>тетрахлорметан</kwd><kwd>соединительнотканные септы</kwd><kwd>морфометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>liver cirrhosis</kwd><kwd>experimental model</kwd><kwd>carbon tetrachloride</kwd><kwd>connective-tissue septa</kwd><kwd>morphometry</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">The Epidemiology of Cirrhosis in the United States: A Population-based Study / S.Scaglione [et al.] // J Clin Gastroenterol.- 2015 - №49(8). - P. 690-696.</mixed-citation><mixed-citation xml:lang="en">The Epidemiology of Cirrhosis in the United States: A Population-based Study / S.Scaglione [et al.] // J Clin Gastroenterol.- 2015 - №49(8). - P. 690-696.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Dunbar,J.K.
