Гистологические препараты печени окрашивали гематоксилином и эозином по методу Маллори. Иммуногистохимическое исследование проводили на парафиновых срезах с использованием моноклональных мышиных антител CD68 и поликлональных кроличьих антител CD206. Степень фиброза определяли согласно полуколичественной шкале Ishak. Токсический фиброз печени до начала процесса трансформации его в цирроз (9 недель) сопровождался ростом количества CD68+ клеток по сравнению с контролем. На всех последующих этапах эксперимента отличий по сравнению с контролем не установлено. В печени контрольных крыс CD206+ клетки практически отсутствовали. На протяжении всего опыта их количество оставалось выше контрольной точки 3 недели. При прогрессировании цирроза печени отмечено снижение количества CD206+ клеток, но уровня третьей недели оно не достигло. Морфологически установили две разные группы CD68+ клеток. Одна группа клеток имела крыловидную форму и располагались они преимущественно в синусоидах печени. Вторая группа CD68+ клеток имела округлую форму и разную локализацию. Они выявлялись вокруг сосудов портальных зон, окружали скопления бурого пигмента в соединительнотканных септах, наблюдались около одиночно лежащих или группы гигантских гепатоцитов и печеночных клеток, содержащих в цитоплазме бурый пигмент, а также отмечались в очагах некроза гепатоцитов. Клетки, экспрессирующие CD206 маркер, были округло вытянутой формы и располагались в синусоидах печени. Предположительно, CD68+ клетки округлой формы выполняют фагоцитарную функцию, а CD68+ клетки крыловидной формы трансдифферецируются в CD206+ клетки, которые обладают противовоспалительными свойствами.</p></abstract><trans-abstract xml:lang="en"><p>   The aim of the work was to evaluate the role of stellate macrophages in a large number of points of toxic liver fibrosis in rats. Liver fibrosis and cirrhosis in male Wistar rats were induced with thioacetamide at a dose of 200 mg/kg animal weight for 17 weeks.</p><p>   Histological preparations of the liver were stained with hematoxylin and eosin according to the Mallory method. Immunohistochemical examination was performed on paraffin sections using monoclonal mouse antibodies CD68 and polyclonal rabbit antibodies CD206. The fibrosis degree was determined according to the Ishak semi-quantitative scale. Toxic liver fibrosis before the start of its transformation into cirrhosis (9 weeks) was accompanied by an increase in the number of CD68+ cells compared with the control. At all subsequent experiment stages, no differences were found in comparison to the control. In the liver of control rats, CD206+ cells were practically absent. Throughout the experiment, their number remained above the control point – 3 weeks. With the progression of liver cirrhosis, a decrease in the number of CD206+ cells was noted, but it did not reach a level of 3 weeks. Morphologically, two different groups of CD68+ cells were identified. One group of cells had a pterygoid shape and they were located mainly in the liver sinusoids. The second group of CD68+ cells had a round shape and different localization. They were detected around the vessels of portal zones, surrounded brown pigment accumulations in connective tissue septa, were observed near single lying groups or groups of giant hepatocytes and liver cells containing brown pigment in the cytoplasm, and were also noted in the foci of necrosis of hepatocytes. Cells, expressing the CD206 marker, are round in shape and are elongated and located in the liver sinusoids. Presumably, round-shaped CD68+ cells perform a phagocytic function, and pterygoid-shaped CD68+ cells transdifferentiate into CD206+ cells that have anti-inflammatory properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крысы</kwd><kwd>тиоацетамид</kwd><kwd>фиброгенез печени</kwd><kwd>шкала Ishak</kwd><kwd>иммуногистохимия</kwd><kwd>звездчатые макрофаги</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rats</kwd><kwd>thioacetamide</kwd><kwd>liver fibrogenesis</kwd><kwd>Ishak score</kwd><kwd>immunohistochemistry</kwd><kwd>stellate macrophages</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках проекта задания государственной программы научных исследований «Изучить роль экспрессии генов NOTCH- и TWEAK-сигнальных путей, участвующих в процессах пролиферации и дифференцировки клеток печени в норме и при ее токсическом поражении» (номер государственной регистрации 20190107)</funding-statement><funding-statement xml:lang="en">The research was conducted within the frames of the theme task of State Research Programs (GPNI) of the Republic of Belarus “To study the role of expression of the NOTCH- and TWEAK signaling pathways genes, participating in the processes of proliferation and diff erentiation of liver cells in the norm and in case of its toxic damage” (№ SR 20190107)</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Papachristoforou, E.
