The oxidation of ethanol under the action of alcohol dehydrogenase leads to a decrease in the amount of reduced glutathione. The aim of the study was an <italic>in vitro</italic> validation of methods for acute and chronic alcoholization in rats. We used acute or chronically alcoholised Wistar rats, that were treated with ACC. The state of the liver was assessed in its perfusates and homogenate. The introduction of ACC after acute ethanol poisoning improves the state of the antioxidant systems of the liver, LPO activity and liver damage. Under conditions of chronic alcoholization, S9 expression increased, but ACC did not affect this change. Thus, a single administration of ethanol increases the content of biochemical markers of liver damage in its perfusate, and chronic administration of ethanol increases the activity of the S9 fraction isolated from the liver of animals.</p></abstract><trans-abstract xml:lang="ru"><p>Алкогольное похмелье требует изучения и разработки терапии. Окисление этанола под действием алкогольдегидрогеназы приводит к уменьшению количества восстановленного глутатиона. Целью работы стала <italic>in vitro</italic> валидация методов острой и хронической алкоголизации. В экспериментах использовали крыс линии Вистар, у которых после острой или хронической алкоголизации с лечением ацетилцистином или без него проводили оценку состояния печени в ее перфузатах и гомогенате. Установили, что введение ацетилцистеина после острого отравления этанолом улучшало состояние антиоксидантных систем печени, активности перекисного окисления липидов и повреждение печени. В условиях хронической алкоголизации усиливалась экспрессия S9, но ацетитлцистеин не оказывал влияния на это изменение. Таким образом, однократное введение этанола увеличивает содержание биохимических маркеров повреждения печени в ее перфузате, а при хроническом введении этанола – увеличивает активность фракции S9 выделенной из печени животных.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hangover</kwd><kwd>S9 fraction</kwd><kwd>rats</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>похмелье</kwd><kwd>фракция S9</kwd><kwd>крысы</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Van Schrojenstein Lantman M., van de Loo A.J., Mackus M., Verster J.C.
