Перевод свиноводства на промышленную основу обуславливает развитие структурно-функциональных изменений в сердечной мышце поросят, которые могут проявиться уже в раннем онтогенезе. Несмотря на достаточно подробное освещение проблемы патологии сердца у сельскохозяйственных животных, в литературе представлено не так много данных об особенностях морфологического изменения миокарда, выявленных с помощью комплекса разных гистохимических методов. Цель данного исследования – изучение патоморфологических изменений миокарда у поросят с использованием гистохимических методов. Для достижения поставленной цели исследован постмортальный материал, отобранный от поросят возраста 1-2 месяцев (n = 3), 3 месяцев (n = 6), 4,5–5,0 месяцев (n = 4). Для морфологического исследования использованы разные гистологические методы окрашивания препаратов: гематоксилином и эозином, по Маллори и ГОФП. Проведено иммуногистохимическое окрашивание с антителами к IL-6. Гистологическое исследование миокарда у поросят в возрасте 1-2 месяцев выявило очаги поврежденной мышечной ткани, характерные для миокардита. Наряду с этим обнаружена положительная реакция кардиомиоцитов на IL-6, предположительно ассоциируемая нами с защитой мышечной ткани. У поросят в возрасте 3 месяцев деструктивные процессы выражены в большей степени, и коррелируют с увеличением площади, занимаемой поврежденными кардиомиоцитами. У поросят в возрасте 4,5–5,0 месяцев, вероятно, ввиду активации компенсаторных механизмов, воспалительные процессы выражены в меньшей степени, а кроме того, обнаруживаются очаги миогенеза. Полученные данные обосновывают дальнейшие исследования, связанные </p></abstract><trans-abstract xml:lang="en"><p>In pigs, as in other farm animals, the health of cardiac muscle is the most important factor determining the general state of the organism, and therefore plays a significant role in improving the quality of the products. Due to industrialization of pig farming, structural and functional changes in cardiac muscle can occur in early ontogenesis. Despite the fairly detailed coverage of the problem of heart pathology in farm animals, the literature does not provide much data on the features of morphological changes in the myocardium identified using a complex of histochemical methods. The objective of the research is to study pathomorphological myocardial changes in piglets using histochemical methods. To achieve this objective, the material collected postmortem from piglets aged 1-2 months (n = 3), 3 months (n = 6), and 4.5-5.0 months (n = 4) was examined. Different histological methods of preparation staining were used for the morphological examination: hematoxylin and eosin, Mallory and HBFP staining. Immunohistochemical staining with antibodies to IL-6 was performed. As a result of histological studies, areas of damaged muscle tissue attributed to myocarditis were detected in the myocardium of piglets aged 1-2 months. At the same time, a positive reaction of cardiomyocytes to IL-6 was detected, which was probably associated with the protection of muscle tissue. In piglets aged 3 months, destructive processes were expressed to a greater extent and they correlated with an increase in the area of damaged cardiomyocytes. In piglets aged 4.5-5.0 months, probably due to the activation of compensatory mechanisms, inflammatory processes were expressed to a lesser extent, and in addition, foci of myogenesis were detected. The data obtained justify further studies related to a more detailed clarification of the mechanisms of destructive processes of the myocardium in pigs of different age.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ГОФП</kwd><kwd>иммуногистохимия</kwd><kwd>IL-6</kwd><kwd>морфологические изменения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>HBFP</kwd><kwd>immunohistochemistry</kwd><kwd>IL-6</kwd><kwd>morphological changes</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет средств гранта Российского научного фонда № 23-16-00117 «Пространственная характеристика транскриптомных и метаболомных особенностей преждевременной структурнофункциональной дегенерации тканей органов сельскохозяйственных животных и птицы», https://rscf.ru/project/23-16-00117</funding-statement><funding-statement xml:lang="en">The research was supported by RSF (project No. 23-16-00117) “Spatial characterization of transcriptomic and metabolomic features of tissue aging processes in farm animals and poultry”. https://rscf.ru/project/23-16-00117</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">Сальникова Е.
