Для доклинических исследований лекарственных средств актуальной задачей является выбор специфических биохимических маркеров, отражающих повреждения центральной нервной системы в токсикологических и фармакологических экспериментах. Одним из таких маркеров может являться белок S100b, уровень которого позволит оценивать повреждение центральной нервной системы различного генеза. Цель. Целью исследования являлась оценка изменения уровня белка S100b в крови крыс и мышей, в гомогенатах головного мозга мышей при повреждениях тканей мозга различного генеза. Материалы и методы. Исследование проводилось на самцах аутбредных крыс и мышей. Суммарно было использовано 62 животных: 47 крыс и 15 мышей. Для определения концентрации белка S100b методом иммуноферментного анализа использовали наборы Lifespan Biosciences (США): Rat S100b/S100 beta Elisa kit (Sandwich Elisa) — для крыс и Mouse S100b/S100 beta Elisa kit (Sandwich Elisa) — для мышей. Статистический анализ выполняли с помощью лицензированного программного обеспечения GraphPad Prism 9. Результаты. Изменения концентрации белка S100b изучали на моделях алкогольной нейропатии, билатеральной и фокальной церебральной ишемии, черепно-мозговой травмы. Формирование всех патологий приводило к повышению концентрации белка S100b как в плазме крови, так и в тканях головного мозга (при черепно-мозговой травме). Для алкогольной нейропатии, фокальной церебральной ишемии и черепно-мозговой травмы изменения уровня этого маркера достигали статистической значимости. Заключение. Повышение концентрации S100b является признаком повреждения нейронов в результате воздействия ишемических, травматических и токсических факторов, а также при гипогликемических состояниях. Таким образом, белок S100b может применяться в доклинических исследованиях в качестве маркера повреждения головного мозга, реагирующего на повреждения различного генеза в исследованиях фармакодинамики и фармакологической безопасности лекарственных препаратов.</p></abstract><trans-abstract xml:lang="en"><p>Background. For preclinical studies of drugs a relevant task is the selection of specific biochemical markers reflecting damage to the central nervous system, both in toxicological and pharmacological experiments. One of such markers may be protein S100b, the level of which will make it possible to assess the damage of the central nervous system of various genesis. Objective. The aim of the study was to assess changes in the level of S100b protein in the blood and in brain homogenates in brain tissue injuries of various genesis. Design and methods. The study was conducted on males of outbred rats and mice. A total of 62 animals were used: 47 rats and 15 mice. To determine the concentration of S100b protein, ELISA kits Rat S100b/S100 beta Elisa kit (Sandwich Elisa) were used) for rats and Mouse S100b/S100 beta Elisa kit (Sandwich Elisa) for mice. Statistical analysis was performed using licensed GraphPad Prism 9 software. Results: Changes of protein S100B was explored on models of alcohol neuropathy, bilateral and focal cerebral ischemia, traumatic brain injury. Forming of all pa[<xref ref-type="bibr" rid="cit1">1</xref>]thologies led to increasing of protein S100B both in blood plasma and in brain tissues in case of traumatic brain injury. For alcohol neuropathy, focal and cerebral ischemia and traumatic brain injury changings of this marker level reached statistic meaning. Conclusion. Increased concentration of S100b is a sign of neuronal damage as a result of ischemic, traumatic and toxic factors, as well as in hypoclycemic conditions. Thus, protein S100b can be used in preclinical studies as a marker of brain damage, responding to damage of various genesis in studies of pharmacodynamics and pharmacological safety of drugs.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алкогольная нейропатия</kwd><kwd>билатеральная ишемия</kwd><kwd>крысы</kwd><kwd>мыши</kwd><kwd>черепно-мозговая травма</kwd><kwd>S100b</kwd></kwd-group><kwd-group xml:lang="en"><kwd>alcoholic neuropathy</kwd><kwd>bilateral ischemia</kwd><kwd>cranio-cerebral trauma</kwd><kwd>mice</kwd><kwd>protein S100b</kwd><kwd>rats</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">Arrais AC, et al.
