Одним из механизмов патологической реакции на длительное воздействие угольно-породной пыли является нарушение баланса про- и антиоксидантов в тканях организма в сторону повышения интенсивности окислительных реакций. Перспективным способом нормализовать этот баланс может быть применение флавоноидов — веществ растительного происхождения, обладающих способностью повышать уровень систем антиоксидантой защиты клеток. Широко распространённым флавоноидом является дигидрокверцетин, для которого в данной работе на различных экспериментальных моделях было показано антигипоксическое, антиоксидантное и органопротекторное действие.</p><p>Цель исследования — изучить органоспецифические эффекты дигидрокверцетина на про- и антиоксидантный баланс в динамике экспериментального пылевого воздействия.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследования проведены на 90 крысах-самцах линии Вистар при угольно-пылевом воздействии в течение 9 недель с одновременным введением препарата — дигидрокверцетина, с последующим изучением начального уровня и скорости накопления продуктов свободнорадикального окисления, активности супероксиддисмутазы и каталазы в лёгких, сердце и печени.</p></sec><sec><title>Результаты</title><p>Результаты. Показаны органоспецифические особенности влияния дигидрокверцетина на про- и антиоксидантный баланс на ранних и поздних сроках угольно-пылевого воздействия. Проявление защитного эффекта дигидрокверцетина можно объяснить его способностью на ранних сроках (1–3 недели) пылевого воздействия индуцировать внутриклеточные антиоксидантные системы (лёгкие и печень), а на поздних (6–9 недели) — проявлять супероксидсвязывающее и каталазоподобное действие (сердце). При длительном применении дигидрокверцетина для профилактики повреждений, вызываемых угольно-породной пылью, особое внимание необходимо уделять ткани печени, высоко чувствительной к чрезмерной активации свободнорадикальных процессов.</p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования.

One of the mechanisms of the pathological reaction to prolonged exposure to coal dust is a violation of the balance of pro- and antioxidants in body tissues in the direction of increasing the intensity of oxidative reactions. Perspective way to normalize this balance may be the use of flavonoids, substances of plant origin that have the ability to increase the level of antioxidant protection systems of cells. A widespread flavonoid is dihydroquercetin, for which antihypoxic, antioxidant and organoprotective effects have been shown in various experimental models in this work.</p><p>The study aims to explore the organ-specific effects of dihydroquercetin on the pro- and antioxidant balance in the dynamics of experimental dust exposure.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Scientists have conducted a study on 90 male Wistar rats exposed to coal dust for 9 weeks with simultaneous administration of the drug dihydroquercetin, followed by studies of the initial level and rate of accumulation of free radical oxidation products, superoxide dismutase and catalase activity in the lungs, heart and liver.</p></sec><sec><title>Results</title><p>Results. The organ-specific features of the effect of dihydroquercetin on the pro- and antioxidant balance in the early and late stages of coal-dust exposure are shown. The protective effect of dihydroquercetin can be explained by its ability to induce intracellular antioxidant systems (lungs and liver) in the early stages (1–3 weeks) of dust exposure, and to exhibit superoxide-binding and catalase-like effects (heart) in the late stages (6–9 weeks). With prolonged use of dihydroquercetin for the prevention of damage caused by coal dust, special attention should be paid to liver tissue, which is highly sensitive to excessive activation of free radical processes.</p></sec><sec><title>Limitations</title><p>Limitations. It is possible that the use of other antioxidant drugs in the dynamics of experimental dust exposure will lead to different results.</p></sec><sec><title>Conclusion</title><p>Conclusion. With prolonged use of drugs with antioxidant properties, it is necessary to study the initial level and rate of accumulation of free radical oxidation products, the activity of antioxidant protection enzymes.</p></sec><sec><title>Ethics</title><p>Ethics.
