К настоящему времени установлены возрастные и половые различия для многих биохимических показателей. Гендерные различия в показателях для таких систем, как антиоксидантная, тиолдисульфидная, систем оксидативного стресса и воспаления отсутствуют или находятся на стадии изучения.</p><p>Цель исследования — выявить гендерные различия в биохимических показателях, отражающих функционирование антиоксидантных систем организма и свободно-радикального окисления у работающих металлургического производства, контактирующих с вредными производственными факторами.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследована кровь мужчин и женщин, работающих на металлургическом предприятии Нижегородской области (n=80) в условиях воздействия комплекса физических и химических производственных факторов. Общий окислительный стресс, общая антиоксидантная способность сыворотки, уровни глутатиона изучались фотометрическими биохимическими методами. Уровни С-реактивного белка и 8-гидрокси–2-дезоксигуанозина изучались методом ИФА.</p></sec><sec><title>Результаты</title><p>Результаты. Среднее количество пероксидов в сыворотке крови у женщин превышало в 1,6 раза данный показатель у мужчин. В группе мужчин содержание 8-ОНdG было выше на 26% (р=0,012), уровень GS — на 12% (р=0,019), активность SOD — в 1,5–2 раза (р=0,0001), уровень СРБ — в 2 раза (р=0,008) по сравнению с аналогичными показателями у женщин.</p></sec><sec><title>Заключение</title><p>Заключение. Исследования гендерных различий у работающих в условиях воздействия вредных производственных факторов позволят с большей эффективностью подойти к вопросам этиологии, лечения и прогноза производственно-обусловленных заболеваний. Показатели оксидативного стресса и антиоксидантной защиты могут явиться индикаторами состояния здоровья работающих в условиях воздействия вредных производственных факторов и иметь важное значение в профилактике заболеваний, связанных с окислительным стрессом.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. To date, age and sex differences have been established for many biochemical parameters. Gender differences in indicators for systems such as antioxidant, thiol-disulfide, oxidative stress and inflammation systems are absent or under study.</p><p>The aim of the study was to identify gender differences in biochemical parameters reflecting the functioning of antioxidant systems of the body and free radical oxidation in workers of metallurgical production, in contact with harmful production factors.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The blood of men and women working at the metallurgical enterprise of the Nizhny Novgorod region (n=80) under the influence of a complex of physical and chemical production factors was studied. Total oxidative stress, total antioxidant capacity of serum, glutathione levels were studied by photometric biochemical methods. Levels of C-reactive protein and 8-hydroxy–2-deoxyguanosine were studied by ELISA.</p></sec><sec><title>Results</title><p>Results. The average amount of peroxides in the serum of women exceeded 1.6 times this figure in men. In the group of men, the content of 8-Ondg was higher by 26% (p=0.012), the level of GS-by 12% (p=0.019), the activity of SOD — by 1.5–2 times (p=0.0001), the level of CRP — by 2 times (p=0.008) compared to similar indicators in women.</p></sec><sec><title>Conclusions</title><p>Conclusions. Studies of gender differences in workers under the influence of harmful production factors will allow more effective approach to the etiology, treatment and prognosis of production-related diseases. Indicators of oxidative stress and antioxidant protection can be indicators of the health of workers under the influence of harmful industrial factors and be important in the prevention of diseases associated with oxidative stress.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>окислительный стресс</kwd><kwd>антиоксидантная способность</kwd><kwd>глутатион</kwd><kwd>8-гидрокси–2-дезоксигуанозин</kwd><kwd>производственные факторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oxidative stress</kwd><kwd>antioxidant capacity</kwd><kwd>glutathione</kwd><kwd>8-hydroxy–2-deoxyguanosine</kwd><kwd>production factors</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">Перепечко В.П., Аристархова О.Ю., Зайратьянц О.В., Верткин А.Л., Дзивина М.И., Адонина Е.В.
