исследования: изучение влияния АКТГ6-9-PGP на уровень депрессивности у крыс в тесте принудительного плавания в сравнении с АКТГ4-7-PGP. </p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Эксперименты выполнены на 90 половозрелых крысах-самцах Вистар массой 250-300 г. Животные были разделены на 9 групп (8 опытных и 1 контрольная) по 10 особей в каждой. В работе применяли физиологический раствор 0,9% натрия хлорида, пептиды АКТГ6-9-PGP и АКТГ4-7-PGP, синтезированные в Институте молекулярной генетики РАН. Пептиды вводили однократно внутрибрюшинно за 15 мин до начала тестирования: АКТГ6-9-PGP в дозах 0,5; 5; 50; 150 и 450 мкг/кг, АКТГ4-7-PGP в дозах 50; 150 и 450 мкг/кг. Депрессивное поведение крыс оценивали с использованием теста принудительного плавания без отягощения. </p></sec><sec><title>Результаты</title><p>Результаты. Внутрибрюшинное введение АКТГ6-9-PGP в дозе 450 мкг/кг способствует уменьшению времени иммобилизации животных и пассивного плавания, а также увеличению длительности их активного плавания, что свидетельствует о наличии антидепрессивного действия пептида. При этом АКТГ4-7-PGP во всех использованных дозах не оказывал существенного влияния на исследуемые показатели поведенческой активности, а его эффекты ограничивались лишь увеличением времени пассивного плавания. </p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, установлено, что АКТГ6-9-PGP, в отличие от АКТГ4-7-PGP, способен обладать антидепрессивным эффектом.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. The aim was to study of the effect of ACTH6-9-PGP on the level of depression in rats in the forced swimming test compared to ACTH4-7-PGP. </p></sec><sec><title>Materials and methods</title><p>Materials and methods. The experiments were performed on 90 mature Wistar male rats weighing 250-300 g. Animals were divided into 9 groups (8 experimental and 1 control) with 10 animals each. A physiological solution of 0.9% sodium chloride, ACTH6-9-PGP and ACTH4-7-PGP peptides synthesized in the Institute of Molecular Genetics, Russian Academy of Sciences, were used in the work. Peptides were administered once intraperitoneally 15 minutes before testing: ACTH6-9-PGP at the doses of 0.5, 5, 50, 150 and 450 μg/kg, ACTH4-7-PGP at the doses of 50, 150 and 450 μg/kg. The depressive behavior of rats was evaluated using a non-burdened forced swimming test. </p></sec><sec><title>Results</title><p>Results. The intraperitoneal administration of ACTH6-9-PGP at a dose of 450 μg/kg helps to reduce the time of animals’ immobilization and passive swimming, as well as to increase the duration of their active swimming, which indicates the presence of the antidepressant effect of the peptide. At the same time, ACTH4-7-PGP at all doses used did not significantly affect the studied indicators of behavioral activity, and its effects were limited only by an increase in the time of passive swimming. </p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, it was found that ACTH6-9-PGP, in contrast to ACTH4-7-PGP, is able to have an antidepressant effect.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>регуляторные пептиды</kwd><kwd>АКТГ</kwd><kwd>депрессия</kwd><kwd>принудительное плавание</kwd><kwd>крысы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>regulatory peptides</kwd><kwd>ACTH</kwd><kwd>depression</kwd><kwd>forced swimming</kwd><kwd>rats</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title></ref-list><fn-group><fn fn-type="conflict"><p>The authors declare that there are no conflicts of interest present.</p></fn></fn-group></back></article>
