Изучить влияние тримебутина на электрическую активность органов желудочно­-кишечного тракта (ЖКТ) в послеоперационный период в условиях эндотоксемии.Материал и методы. Исследования выполнены на 13 половозрелых крысах­самцах линии Вистар. Животным во время лапаротомии были вживлены зонд в тощую кишку и электроды в стенку антральной части желудка, двенадцатиперстной кишки (ДПК) и тощей кишки.Интраоперационно в бедренную вену вводился раствор липополисахарида Escherichia coli serotype 055:B5 в дозе 200 мкг/кг. Исследованы две группы крыс, которым в первые 3 сут после операции вводили внутрикишечно однократно физиологический раствор 0,2 мл (контрольная группа, n=7) и тримебутин в дозе 2,86 мг/кг в объеме 0,2 мл (опытная группа, n=6). Электрическая активность исследуемых отделов ЖКТ регистрировали методом электромиографии в течение часа (фон) и 2 ч после введения лекарственного вещества.Результаты. В контрольной группе на протяжении 3 сут после операции наблюдались значительное снижение показателя антродуоденальной координации и отсутствие фазы III мигрирующего миоэлектрического комплекса (ММК) в ДПК и тощей кишке. На 2-­е и 3­-и сутки в ДПК и тощей кишке отмечалось появление патологических паттернов моторики – высокоамплитудной спастической активности и гигантских мигрирующих спайков (ГМС). Нормализация показателя антродуоденальной координации и ММК выявлялась лишь к 8-­м суткам после операции.В опытной группе введение тримебутина в течение 3 сут после операции кардинальным образом изменяло динамику электрической активности отделов ЖКТ. Уже на 3-­и сутки в фоновых записях показатель антродуоденальной координации не отличался от нормальных значений. К 4-­м суткам в ДПК и тощей кишке регистрировался ММК. В послеоперационный период во все сроки наблюдения не отмечалось эпизодов высокоамплитудной спастической активности и ГМС.Выводы. В ранний послеоперационный период в условиях эндотоксемии происходят значительные нарушения в генерации ММК с появлением патологических паттернов моторики в виде ГМС и спастической активности. Введение тримебутина в этих условиях является эффективным, что обусловлено отсутствием патологических паттернов моторики, ускорением нормализации антродуоденальной координации и быстрым восстановлением распространения ММК из ДПК в тощую кишку.</p></abstract><trans-abstract xml:lang="en"><sec><title>Aim of investigation</title><p>Aim of investigation. To study the effect of trimebutine on electrical activity of organs of gastro-intestinal tract (GIT) in postoperative period at endotoxemia state.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was carried out at 13 nubilous Wistar male rats. Animal had a tube in jejunum and electrodes — in the wall of stomach antrum, duodenum and jejunum — implanted during laparotomy. Solution of lipopolysaccharide of Escherichia coli serotype 055:B5 in a dose of 200 mkg/kg was injected intraoperatively into femoral vein. Two groups of rats were studied: the first had single injection of 0,2 ml normal saline solution intraintestinally for the first 3 days after operation (control group, n=7) while the second — 0,2 ml of trimebutine solution in a dose of 2,86 mg/kg (main group, n=6). Electrical activity of investigated regions of GIT was recorded by electromyography for one hour (background) and for 2 hs after injection of medicine.</p></sec><sec><title>Results</title><p>Results. In the control group during 3 days after operation significant decrease in score of antroduodenal coordination and absence of phase III of migrating myoelectric complex (MMC) in duodenum and jejunum was observed. On the 2 and 3 day appearance of pathological motility patterns: high-amplitude spastic activity and giant migrating spikes (GMS) in duodenum and jejunum was marked. Normalization of antroduodenal coordination and MMC was noticed only to the 8-th day after surgery. In the main group injection of trimebutine during 3 days after operation cardinally changed dynamics of electrical activity of GIT regions. Already on the 3-rd day in background records the score of antroduodenal coordination did not differ from normal values. On the 4-th day in duodenum and jejunum MMC was recorded. In postoperative period in all terms no episodes of high-amplitude spastic activity or GMS were observed.</p></sec><sec><title>Conclusions</title><p>Conclusions. In early postoperative period in conditions of endotoxemia there are significant disorders in MMC generation with appearance of pathological motility patterns like GMS and spasmodic activity. Injection of trimebutine in these conditions is effective, that is proved by absence of pathological patterns of motility, more rapid normalization of antroduodenal coordination and faster restoration of MMC spread from duodenum to jejunum.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>электрическая активность желудка и тонкой кишки</kwd><kwd>эндотоксин</kwd><kwd>мигрирующий миоэлектрический комплекс</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electrical activity of the stomach and small intestine</kwd><kwd>endotoxin</kwd><kwd>migrating myoelectric complex</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">Карпов И.А., Овечкин А.М.
