Restoration of NAD+/NADH ratio provided preservation of redox potential in liver, necessary level of oxidized forms of metabolites of lactate dehydrogenase and glycerol-3-phosphate dehydrogenase shuttle cycles for maintenance of reactions of aerobic glycolysis and gluconeogenesis, pentose phosphate cycle, promoted prevention of tissue hypoxia and normalization of blood glucose level. This provides a basis for recommending the use of florotannin complexes as a prophylactic agent to attenuate the toxic effects of ethanol.</p></abstract><trans-abstract xml:lang="ru"><p>Показано, что комплекс флоротаннинов, выделенный из морской бурой водоросли <italic>Sargassum pallidum</italic>, предохранял пул окисленной формы НАД<sup>+</sup>–НАДФ<sup>+</sup> от истощения при острой алкогольной интоксикации. Восстановление соотношения НАД<sup>+</sup>/НАДН обеспечило сохранение окислительно-восстановительного потенциала в печени, необходимый уровень окисленных форм метаболитов лактат-дегидрогеназного и глицерол-3-фосфатдегидрогеназного челночных циклов для поддержания реакций аэробного гликолиза и глюконеогенеза, пентозофосфатного цикла, способствовало предотвращению состояния тканевой гипоксии и нормализации уровня глюкозы крови. Это дает основание для рекомендации применения комплексов флоротаннинов в качестве средства профилактики ослабляющего токсические проявления этанола.</p></trans-abstract><kwd-group xml:lang="en"><kwd>florotannins</kwd><kwd>Sargassum pallidum</kwd><kwd>ethanol</kwd><kwd>carbohydrate metabolism</kwd><kwd>alcohol intoxication</kwd><kwd>prevention</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>флоротаннины</kwd><kwd>Sargassum pallidum</kwd><kwd>этанол</kwd><kwd>углеводный обмен</kwd><kwd>алкогольная интоксикация</kwd><kwd>профилактика</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>124022100077-0</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Боголицын К.Г., Дружинина А.С., Овчинников Д.В., Каплицин П.А., Шульгина Е.В., Паршина А.Э.
