Morphofunctional changes occurring in the liver in response to fecal peritonitis allow a better understanding of this relationship. Despite the existing researches, some aspects of the pathological changes occurring in the liver in fecal peritonitis require a special study.</p> <p>Purpose: to describe the composition and dynamics of the lymphocytic-leukocytic infiltrate in the liver in conditions of experimental fecal peritonitis.</p> <p>The study was conducted on Balb/c (n=5) mice with artificially induced fecal peritonitis. One animal was euthanized on 1, 3, 5, 7 and 14 day of the experiment. Immunophenotyping of inflammatory infiltrate cells was performed on liver tissue samples using antibodies to CD3, CD45, CD163. Morphometric analysis was carried out with the calculation of the number of cells per unit area.</p> <p>It was shown that the highest intensity of infiltration by CD45<sup>+</sup>-cells is observed on the 3rd day of the experiment with a subsequent decrease; infiltration by CD3<sup>+</sup>-cells increases by the 5th day of the experiment without further dynamics; infiltration of CD163<sup>+</sup>-cells — by day 7 without further changes.</p> <p>Conclusions: the severity of the liver parenchyma infiltration by immune cells in dynamics reflects the organ reaction to experimental fecal peritonitis.</p></abstract><trans-abstract xml:lang="ru"><p>Взаимоотношения печени и брюшины — важный элемент поддержания гомеостаза организма. Морфофункциональные изменения, происходящие в печени при воспалении брюшины в случае развития калового перитонита, позволяют дополнить известные сведения о его патоморфогенезе.</p> <p>Цель работы: описать состав и динамику клеточного инфильтрата в тканях печени в условиях экспериментального калового перитонита.</p> <p>Исследование проведено на мышах породы Balb/c (n=15) с искусственно вызванным каловым перитонитом. По 3 животных выводили из эксперимента через 1, 3, 5, 7, 14 сут. после внутрибрюшинного помещения каловых масс. Образцы фрагментов печени были обработаны по стандартному гистологическому протоколу, окрашены гематоксилином и эозином, выполнено иммунофенотипирование клеток воспалительного инфильтрата с использованием антител к CD45, CD3, CD163. Проведен морфометрический анализ.</p> <p>Установлено, что наибольшая выраженность инфильтрации CD45<sup>+</sup>-клетками развивается к 3 сут. эксперимента, в дальнейшем число лейкоцитов в печени снижается; доля CD3<sup>+</sup>-клеток в инфильтрате максимальна через 5 сут.; инфильтрация CD163<sup>+</sup>-М2-макрофагами достигает пика к 7 сут.</p></trans-abstract><kwd-group xml:lang="en"><kwd>peritoneum</kwd><kwd>liver</kwd><kwd>fecal peritonitis</kwd><kwd>immunophenotyping</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>брюшина</kwd><kwd>печень</kwd><kwd>каловый перитонит</kwd><kwd>иммунофенотипирование</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Луцевич О.Э., Акимов В.П., Ширинский В.Г. и др.
