The depth and degree of brain damage due to ischemia are reflected in its bioelectrical activity. This makes it possible to use the electrocorticography or intracranial electroencephalography (EEG) as a tool for evaluating the effectiveness of neuroprotective therapy. In the present study the neuroprotective properties of the experimental compound RU-1205 and the kappa-opioid agonist butorphanol were analyzed. The neuroprotective effect of the substances was assessed by measuring the extent of the neurological deficit and the changes in bioelectrical activity of the ischemic brain of rats. Compound RU-1205 (10 mg/kg, i.v.) as well as the reference drug butorphanol (2,5 mg/kg, i.v.) restored to normal neurological status and power of the EEG signal in delta and theta frequency bands.</p></abstract><trans-abstract xml:lang="ru"><p>Высокая распространенность и тяжесть осложнений ишемического инсульта диктуют необходимость в разработке препаратов с нейропротекторной активностью. Учитывая, что глубина и степень поражения мозга при ишемии коррелируют с изменениями биоэлектрической активности, электрокортикография или внутричерепная электроэнцефалография (ЭЭГ) может выступать в качестве инструмента для оценки эффективности нейропротекторной терапии. В исследовании был проведен анализ нейропротекторных свойств веществ с каппаопиоидной активностью -соединения РУ-1205 и буторфанола. Нейропротективное действие веществ оценивалось по степени изменения неврологического дефицита и влиянию на биоэлектрическую активность ишемизированного мозга крыс. Соединение РУ-1205 (10 мг/кг, в/в) в равной степени с препаратом сравнения буторфанолом (2,5 мг/кг, в/в) способствовало нормализации неврологического статуса и мощности ЭЭГ-сигнала в дельта- и тета-диапазонах частот.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ischemic stroke</kwd><kwd>global ischemia</kwd><kwd>neuroprotectors</kwd><kwd>kappa-opioid agonists</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ишемический инсульт</kwd><kwd>глобальная ишемия</kwd><kwd>нейропротекторы</kwd><kwd>каппа-опиоидные агонисты</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Спасов А.А., Гречко О.Ю., Калитин К.Ю., Анисимова В.А.
