Разработка новых фармакологических агентов для защиты миокарда при реперфузионном повреждении является актуальной задачей современной физиологии и фармакологии.Целью настоящего исследования явилось выявление потенциальной возможности защиты миокарда от реперфузионного повреждения при помощи введения агониста дельта-2 опиоидных рецепторов дельторфина-II перед началом реперфузии у старых крыс при индуцированном диетой метаболическом синдроме.Методы. Исследование выполнено на крысах Вистар в возрасте до начала эксперимента 60 дней (молодые крысы) и 450 дней (старые крысы). Метаболический синдром (МетС) моделировали в течение 84 дней высокоуглеводной высокожировой диетой (16 % белков, 21 % жиров, 46 % углеводов) с заменой питьевой воды на 20%-й раствор фруктозы. Инфаркт миокарда воспроизводили 45-минутной коронароокклюзией с последующей 120-минутной реперфузией, определяли размер области некротизированного миокарда относительно размера зоны гипоперфузии. Агонист дельта-2 опиоидных рецепторов дельторфин-II вводили однократно внутривенно за 5 минут до окончания ишемии.Результаты. Обнаружено, что моделирование коронароокклюзии и последующей реперфузии как в группе молодых, так и у старых крыс приводило к формированию инфаркта (некроза) миокарда, размер которого составлял 45 % от размера зоны риска. Применение дельторфина-II у старых крыс приводило к ограничению размера инфаркта до 27 %, то есть в 1,7 раза. Применение дельторфина-II у старых крыс с МетС способствовало снижению размера инфаркта до 30 % от размера зоны риска (в 1,5 раза).Заключение. Полученные результаты свидетельствуют о кардиопротекторной эффективности агониста дельта-2 опиоидных рецепторов дельторфина-II при старении и метаболическом синдроме у крыс. Эти данные могут служить основанием для проведения доклинических исследований дельторфина-II в качестве препарата для лечения острого инфаркта миокарда.</p></abstract><trans-abstract xml:lang="en"><p>Background. The discovery of new pharmacological agents for myocardial protection during reperfusion injury is an urgent goal of modern physiology and pharmacology.The aim of the study. To identify the potential for protecting the myocardium from reperfusion injury by administering the delta-2 opioid receptor agonist deltorphin-II prior to reperfusion in old rats with diet-induced metabolic syndrome.Materials and methods. The study was performed on Wistar rats aged 60 days (young rats) and 450 days (old rats) before the onset of a study. Metabolic syndrome (MetS) was modeled for 84 days with a high-carbohydrate high-fat diet (16 % protein, 21 % fat, 46 % carbohydrate) with the replacement of drinking water with 20 % fructose solution. Myocardial infarction was performed by 45-min coronary occlusion followed by 120-min reperfusion; the size of the area of the necrotic myocardium was determined relative to the size of the hypoperfusion zone. The delta-2 opioid receptor agonist deltorphin-II was administered once intravenously 5 minutes before the end of ischemia.Results. It was found that coronary occlusion and subsequent reperfusion both in groups of young and old rats led to the formation of myocardial infarction (necrosis), the size of which was 45 % of the size of the risk zone. Administration of deltorphin-II in old rats led to a limitation of infarct size to 30 % of the size of the risk zone, i. e. 1.7-fold. The use of deltorphin-II in old rats with MetS contributed to a decrease in infarct size to 27 % of the size of the risk zone (1.5 times). The obtained results demonstrate the cardioprotective efficacy of the delta-2 opioid receptor agonist deltorphin-II in aging and metabolic syndrome in rats.Conclusions. These data may serve as a basis for conducting preclinical studies of deltorphin-II as a drug for treatment of acute myocardial infarction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>миокард</kwd><kwd>реперфузия</kwd><kwd>метаболический синдром</kwd><kwd>возраст</kwd><kwd>опиоидные рецепторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>myocardium</kwd><kwd>reperfusion</kwd><kwd>metabolic syndrome</kwd><kwd>age</kwd><kwd>opioid receptors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Российского научного фонда (грант № 22-15-00048).
