Исследование выполнено на 55 самцах крыс линии Вистар, которые были разделены на пять групп (n = 11): 1 – контрольная группа (введение физиологического раствора без стрессирования); 2 – хронический иммобилизационный стресс (ХИС) + введение физиологического раствора; 3 – ХИС + введение АКТГ6-9-ПГП в дозе 5 мкг/кг; 4 – 50 мкг/кг; 5 – 500 мкг/кг. Проводили гистологическое исследование толстой кишки крыс. Изучали гистоархитектонику стенки толстой кишки, глубину крипт, число бокаловидных клеток в них. Подсчитывали число гранулоцитов, плазмацитов, лимфоцитов, макрофагов и тучных клеток.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что хронический (14 сут) иммобилизационный стресс приводит к развитию воспалительных процессов в стенке толстой кишки животных. Внутрибрюшинное введение АКТГ6-9-ПГП в дозах 50 и 500 мкг/кг 1 раз/сут на протяжении всего времени стрессорного воздействия препятствовало развитию наблюдавшихся у контрольных животных стресс-индуцированных сдвигов. При этом отмечались противовоспалительные эффекты пептида в стенке толстой кишки и снижение уровня кортикостерона в сыворотке крови.</p></sec><sec><title>Заключение</title><p>Заключение. Результаты свидетельствуют о необходимости продолжения изучения механизмов их влияния на процессы воспаления и поиска мишеней АКТГ6-9-ПГП.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the morphofunctional state of the colonic wall in rats when using the N–terminal analog of the adrenocorticotropic hormone (ACTH) ACTH6-9-Pro-Gly-Pro (ACTH6-9-PGP) peptide under chronic stress.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was performed on 55 male Wistar rats, which were divided into 5 groups (n = 11): group 1 – control group (administration of saline solution without stress); group 2 – chronic restraint stress (CRS) + administration of saline solution; group 3 – CRS + administration of ACTH6-9-PGP at a dose of 5 μg / kg; group 4 – administration of ACTH6-9-PGP at a dose of 50 μg / kg; group 5 – administration of ACTH6-9- PGP at a dose of 500 μg / kg. A histologic examination of the rat colon was performed. The histologic architecture of the colonic wall, the depth of crypts, and the number of goblet cells were assessed. Furthermore, the number of granulocytes, plasma cells, lymphocytes, macrophages, and mast cells was counted.</p></sec><sec><title>Results</title><p>Results. The study demonstrated that chronic (14 days) restraint stress resulted in the development of inflammations in the colonic wall of the animals. Intraperitoneal administration of ACTH6-9-PGP at doses of 50 and 500 μg / kg daily throughout the entire time of stress exposure prevented the development of stress-induced alterations observed in the control animals. At the same time, anti-inflammatory effects of the peptide in the colonic wall and a decrease in the level of corticosterone in the blood serum were noted.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results of this work and data from other studies on the effects of N-terminal analogs of ACTH indicate the need for studying the mechanisms of their effect on inflammation and searching for targets of ACTH6-9-PGP. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>АКТГ6-9-ПГП</kwd><kwd>крысы линии Вистар</kwd><kwd>хронический иммобилизационный стресс</kwd><kwd>толстая кишка</kwd><kwd>воспаление</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ACTH6-9-PGP</kwd><kwd>Wistar rats</kwd><kwd>chronic restraint stress</kwd><kwd>colon</kwd><kwd>inflammation</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">Catania A.
