The control group included five intact animals, group 1 was treated with Baclofen at a dose of 85 mg/kg, group 2 — with a combination of Baclofen (85 mg/kg) and ethanol (7 mL/kg of 40% ethanol). <bold>Results.</bold> No pathological changes were observed in the lungs of the controls. Both treated groups manifested the capillary and venous plethora, sludge syndrome, atelectases and dystelectases, emphysema and infiltration of white blood cells into the interalveolar septa. Bronchioles in the group 2 animals contained secretion. <bold>Conclusion.</bold> In the conducted trials, a complex of pathological changes was observed in the lungs of animal models shortly after the administration of Baclofen, including circulatory disorders in all departments of the microcirculatory bed (plethora of capillaries and venules), emphysema, atelectases and dystelectases, leucocyte infiltration into the interalveolar septa. Morphometric studies are necessary to quantify the severity of histomorphological changes in the lungs.</italic></p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Цель</italic></bold><italic> — выявление и оценка гистоморфологических изменений в легких при острых отравлениях баклофеном и его комбинацией с этанолом через 3 часа после отравления. <bold>Материал и методы.</bold> Экспериментальные исследования проводили на 15 крысах линии Wistar, распределенных на 3 группы. Контрольная группа включала в себя 5 интактных животных, группа 1 получала баклофен в дозе 85 мг/кг, группа 2 — комбинацию баклофена (85 мг/кг) и этанола (7 мл/кг 40% этанола). <bold>Результаты.</bold> В легких животных контрольной группы патологических изменений не наблюдалось. В обеих экспериментальных группах наблюдали капиллярное и венозное полнокровие, сладж, наличие ателектазов и дистелектазов, эмфиземы, лейкоцитарной инфильтрации межальвеолярных перегородок. В бронхиолах животных второй группы наблюдали наличие секрета. <bold>Заключение.</bold> В результате проведенных экспериментов в легких подопытных животных в ранние сроки после введения баклофена нами был выявлен комплекс патологических изменений, включающий в себя нарушения кровообращения во всех элементах микроциркуляторного русла (полнокровие капилляров, венул), появление эмфиземы, ателектазов и дистелектазов, лейкоцитарной инфильтрации межальвеолярных перегородок. С целью количественной оценки выраженности гистоморфологических изменений в легких целесообразно проведение морфометрического исследования.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>Baclofen</kwd><kwd>ethanol</kwd><kwd>lungs</kwd><kwd>poisoning</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>баклофен</kwd><kwd>этанол</kwd><kwd>легкие</kwd><kwd>отравление</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Baclofen Monograph for Professionals.
