Материалы и методы. Материалом исследования были белые беспородные крысы-самцы массой 180-200 грамм. Изучаемыми токсикантами явились: ТХМ, этанол, парацетамол. В качестве гепатопротекторов вводились: ОМУ, Гептор и Мексидол. Производили выделение РНК, которую подвергали обратной транскрипции. ОТ-ПЦР проводили с использованием системы для ПЦР в реальном времени в присутствии SYBR Green. В качестве нормализованного контроля использовали GAPDH. Экспрессию изучаемых генов оценивали с помощью анализа ПЦР с использованием заранее подобранных праймеров. Статистическую значимость проверяли с программного обеспечения IBM SPSS Statistics. Результаты. В сравнении экспериментальных групп по уровню экспрессии гена CASP7 были обнаружены статистически достоверные различия. Транскрипционная активность гена CHEK (к=11,25; р=0,024). Ген GCLC (к=21,70; р=0,001) достиг своего минимального значения -3,6 [-3,72; -3,32] в группе Мексидола. Кратность экспрессии гена GSTM1 (к=15,54; р=0,004) имела наибольшее значение -0,14 [-1,11; 1] в группе не получавшей ТХМ. Ген NQO1 достиг своей статистической значимости при 72-часом эксперименте (р=0,005). Статистический анализ гена RIPK показал значимые различия. Уровень экспрессии гена GSTP1 (к=10,39; р=0,034) достиг своего максимального значения в группе без лечения 0,03 [-0,74; 0,48]. Экспрессия гена NFE2L2 при введении ацетаминофена показал следующие результаты (к=13,64; р=0,009). Активность глутатиона (к=10,29; р=0,036) достигала своего минимального значения в группе, получавшей Мексидол -1,6 [-1,7; -1,29]. Кратность экспрессии супероксиддисмутазы показала статистическую значимость (р=0,003). Заключение. Найдены маркеры клинического течения, прогноза и исходов токсического гепатита. Эти данные позволяют определять тяжесть заболевания на стадии раннего молекулярного ответа, когда еще не развилась активная клиническая симптоматика, что дает возможность назначать таргетную терапию и корректировать тактику лечения.</p></abstract><trans-abstract xml:lang="en"><p>The study aims to study of changes in transcriptional activity of oxidative stress genes in acute toxic hepatitis. Materials and methods. The study material was white mongrel male rats weighing 180-200 grams. The studied toxicants were: carbon tetrachloride, ethanol, acetaminophen. As hepatoprotectors were introduced: oxymethyluracil, ademethionine and ethylmethylhydroxypyridine succinate. RNA was isolated, which was subjected to reverse transcription. RT-PCR was performed using a real-time PCR system in the presence of SYBR Green. GAPDH was used as a normalized control. The expression of the studied genes was evaluated by PCR analysis using pre-selected primers. Statistical significance was checked using IBM SPSS Statistics software. Results. In comparison of experimental groups, statistically significant differences were found in the level of expression of the CASP7 gene. Transcriptional activity of the CHEK gene (k=11.25; p=0.024). The GCLC gene (k=21.70; p=0.001) reached its minimum value of -3.6 [-3.72; -3.32] in the Mexidol group. The multiplicity of expression of the GSTM1 gene (k=15.54; p=0.004) had the highest value -0.14 [-1.11; 1] in the group that did not receive TCM. The NQO1 gene achieved its statistical significance in a 72-hour experiment (p=0.005). Statistical analysis of the RIPK gene showed significant differences. The expression level of the GSTP1 gene (k=10.39; p=0.034) reached its maximum value in the untreated group of 0.03 [-0.74; 0.48]. Expression of the NFE2L2 gene with acetaminophen administration showed the following results (k=13.64; p=0.009). Glutathione activity (k=10.29; p=0.036) reached its minimum value in the group receiving Mexidol -1.6 [-1.7; -1.29]. The multiplicity of superoxide dismutase expression showed statistical significance (p=0.003). Conclusions. Markers of the clinical course, prognosis and outcomes of toxic hepatitis were found. These data make it possible to determine the severity of the disease at the stage of early molecular response, when active clinical symptoms have not yet developed, which makes it possible to prescribe targeted therapy and adjust treatment tactics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>экспрессия генов</kwd><kwd>токсический гепатит</kwd><kwd>оксидативный стресс</kwd><kwd>коррекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gene expression</kwd><kwd>toxic hepatitis</kwd><kwd>oxidative stress</kwd><kwd>correction</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">Opitz C.
