Изучить влияние внутривенной инфузии инновационного препарата метилин, разработанного в ФГБУ «НМИЦ кардиологии» Минздрава России, обладающего антиишемическими и антиоксидантными свойствами на показатели функции сердца кроликов in vivo, поврежденных длительным введением доксорубицина. Материалы и методы. Животным опытной группы внутривенно вводили доксорубицин (2 мг на 1 кг массы тела 1 раз в неделю) в течение 8 нед, животным контрольной группы - изотонический раствор натрия хлорида. Повреждение миокарда оценивали по содержанию малонового диальдегида (МДА), тропонина I (TnI), фракции MB креатинкиназы (КК-MB) в венозной крови и по изменениям структуры левого желудочка (ЛЖ) сердца при морфологическом исследовании. Влияние метилина на функцию сердца оценивали с помощью эхокардиографии и катетеризациии ЛЖ Милларовским катетером. Результаты. Введение доксорубицина сопровождалось снижением массы тела животных, увеличением содержания маркеров повреждения сарколеммы КК-MB и тропонина, продукта перекисного окисления липидов МДА в венозной крови и нарушениям структуры мышечных волокон и микрососудов ЛЖ. Одновременно снижались показатели сократимости миокарда - увеличивались конечные диастолический и систолический размеры и уменьшались фракции укорочения и выброса по сравнению с исходными значениями. Эти изменения указывали на развитие у животных хронической сердечной недостаточности (ХСН). На этом фоне внутривенная инфузия метилина достоверно увеличивала фракции укорочения и выброса. Положительное действие метилина на показатели сократимости и расслабимости сердца сохранялось в течение 30 мин после прекращения инфузии. Метилин оказывал большее влияние на показатели функции сердца кроликов с ХСН по сравнению с животными контрольной группы, не получавших доксорубицин. Заключение. Полученные результаты указывают на возможность использования метилина для снижения дисфункции ЛЖ при ХСН.</p></abstract><trans-abstract xml:lang="en"><p>Aim. To study effects of intravenous infusion of a cardioprotective drug metilin, developed at the “National Medical Research Center of Cardiology” on indices of cardiac function in rabbits in vivo after prolonged administration of doxorubicin. Materials and Methods. Animals of the experimental group were intravenously injected with doxorubicin (2 mg/kg once a week) for 8 weeks, animals of the control group received the same volume of saline. Myocardial damage was characterized by an increase in concentration of malondialdehyde (MDA), troponin (TnI) and MB-fraction of creatine kinase (CK-MB) in venous blood and by disturbances in the left ventricle (LV) structure at morphological examination. Metilin effects on cardiac function were assessed by echocardiography and LV catheterization by the Millar catheter tip pressure transducer. Results. Doxorubicin administration led to a decrease of the body mass of animals, an increase of the plasma concentration of cardiac markers CK-MB and TnI, lipid peroxidation (LPO) product MDA in venous blood, and pronounced disturbances in the structure of LV fibers and microvessels. At the same time, a significant decrease of myocardial contractility indices was observed. Manifestations of this decrease were increase of the end-diastolic and end-systolic dimensions (EDD and ESD, respectively), and decreases in the shortening fraction and ejection fraction (SF and EF, respectively) com pared to baseline values. These changes indicated development of chronic heart failure (CHF) in animals of the experimental group. Against this background, intravenous infusion of metilin significantly increased SF and EF, but did not affect the heart rate. Beneficial effects of metilin on the indices of cardiac contractility and relaxation were maintained after the infusion was stopped. Noteworthy, metilin exerted greater influence on cardiac function of rabbits with CHF compared to control animals that did not receive doxorubicin. Conclusion. The obtained results indicate the potential of metilin to reduce LV dysfunction during chemotherapy with doxorubicin.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метилин</kwd><kwd>хроническая сердечная недостаточность</kwd><kwd>доксорубицин</kwd><kwd>функция сердца</kwd><kwd>кролики</kwd><kwd>metilin</kwd><kwd>CHF</kwd><kwd>doxorubicin</kwd><kwd>cardiac function</kwd><kwd>rabbits</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">Carvalho C., Santos R.
