Установлено, что ЭпА после введения бемегрида появляется через 1–2 мин в виде продолжительных генерализованных высокоамплитудных разрядов и регистрируется в течение 3 часов. ГИЖ-290 (5 мг/кг, внутрибрюшинно, через 15 мин после бемегрида) вызывает достоверное (р ≤ 0,05) уменьшение числа эпилептических разрядов в коре и на уровне тенденции в гиппокампе, что сопровождается уменьшением амплитуды Эпи разрядов. Леветирацетам в дозе 200 мг/кг достоверно не изменяет выраженность пароксизмальной активности (число судорожных разрядов и их длительность), вызванной бемегридом.</p></abstract><trans-abstract xml:lang="en"><p>The effect of levetiracetam (a derivative of 4-phenylpyrrolidone) and its original analog, the compound GIZH-290, on primary generalized epileptic activity (EpA) in rat brain structures (sensorimotor cortex, dorsal hippocampus-CA3 field and lateral hypothalamus field) on EEG models of bemegridinduced seizures was studied. It was found that EpA, after the introduction of bemegrid, appears in 1–2 minutes in the form of prolonged generalized high-amplitude discharges and is registered within 3 hours. GIZH-290 (5 mg/kg, intraperitoneal, 15 minutes after bemegrid) causes a significant (p &lt; 0.05) decrease in the number of epileptic discharges in the cortex and at the level of the trend in the hippocampus, which is accompanied by a decrease in the amplitude of the Epi-discharges. Levetiracetam at a dose of 200 mg / kg does not significantly change the severity of paroxysmal activity (the number of convulsive discharges and their duration) caused by bemegrid.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>леветирацетам</kwd><kwd>соединение ГИЖ-290</kwd><kwd>фенил-пирролидон</kwd><kwd>бемегрид</kwd><kwd>ЭЭГ модель судорог</kwd><kwd>эпилепсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>levetiracetam</kwd><kwd>GIZH -290 compound</kwd><kwd>phenyl-pyrrolidone</kwd><kwd>bemegrid</kwd><kwd>EEG model of seizures</kwd><kwd>epilepsy</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">Воронина Т.А., Авакян Г.Г., Неробкова Л.Н. и др.
