В последние годы в научной литературе стали появляться данные о влиянии дельтаметрина и других синтетических пиретроидов на репродуктивную систему и, в частности, на качество семенной жидкости. При этом механизмы развития этих нарушений глубоко не раскрыты. Цель данной работы - определить пусковые механизмы окислительного стресса в органах репродуктивной системы у крыс при воздействии на организм дельтаметрина. Исследование проведено на 48 лабораторных крысах-самцах с массой тела 230-250 г. Метаболические изменения в семенниках после однократного введения дельтаметрина в дозе 17,4 мг/кг массы тела (1/5 ЛД50) оценивали через 1 и 3 суток. Критериями оценки служили содержание в органах репродуктивной системы пировиноградной, молочной и мочевой кислот, неорганического фосфата (Фн), глутатиона, малонового диальдегида (МДА), активность глутатионпероксидазы (ГПО) и глутатионредуктазы (ГР). Полученные результаты подвергали статистической обработке. Введение дельтаметрина лабораторным крысам в дозе 1/5 ЛД50 вызывает изменения метаболизма в органах репродуктивной системы: семенниках, эпидидимисе, предстательной железе и семенных пузырьках. Через 1-3 суток у крыс отмечается увеличение содержания в органих лактата, пирувата, урата, Фн и МДА. Это свидетельствует о нарушении энергетического обмена и усилении процессов липопероксидации, что ведет и снижению уровня глутатиона. Дефицит глутатиона усугубляется повышением активности антиоксидантных ферментов (ГПО и ГР). Пусковым механизмом развития окислительного стресса в органах репродуктивной системы является нарушение энергетического обмена, вызванное глубоким катаболизмом пуринов до мочевой кислоты. Этот процесс сопровождается усиленной генерацией свободных радикалов и истощением пула неферментативных антиоксидантов. Снижение функции антиоксидантной системы на фоне накопления в органах репродуктивной системы МДА свидетельствует о развитии окислительного стресса.</p></abstract><trans-abstract xml:lang="en"><p>Deltamethrin is widely used in agriculture and veterinary medicine. In recent years, data have begun to appear in the scientific literature on the effect of deltamethrin and other synthetic pyrethroids on the reproductive system and, in particular, on the quality of seminal fluid. However, the mechanisms of development of these disorders are not fully understood. The purpose of this work is to determine the triggers of oxidative stress in reproductive organs of rats exposed to deltamethrin. The study was conducted on 48 male laboratory rats with a body weight of 230-250 g. Metabolic changes in the testes after a single administration of deltamethrin at a dose of 17.4 mg/kg body weight (1/5 LD50) were assessed after 1 and 3 days. The evaluation criteria were the content of pyruvic, lactic and uric acids, inorganic phosphate (Pi), glutathione, malondialdehyde (MDA), the activity of glutathione peroxidase (GPx) and glutathione reductase (GR) in the organs of the reproductive system. The obtained results were subjected to statistical processing. Administration of deltamethrin to laboratory rats at a dose of 1/5 LD 50 causes changes in metabolism in the reproductive organs: testicles, epididymis, prostate gland and seminal vesicles. After 1-3 days, an increase in the content of lactate, pyruvate, urate, Pi, and MDA in the rats' organs was noted. This indicates a violation of energy metabolism and increased lipoperoxidation processes, which leads to a decrease in glutathione levels. Glutathione deficiency is aggravated by the increased activity of antioxidant enzymes (GPx and GR). The trigger mechanism for the development of oxidative stress in the organs of the reproductive system is the disruption of energy metabolism caused by the deep catabolism of purines to uric acid. This process is accompanied by increased generation of free radicals and depletion of the pool of non -enzymatic antioxidants. A decrease in the function of the antioxidant system against the background of MDA accumulation in the organs of the reproductive system indicates the development of oxidative stress.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>репродуктивная система</kwd><kwd>энергетический обмен</kwd><kwd>окислительный стресс</kwd><kwd>дельтаметрин</kwd><kwd>крысы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>reproductive system</kwd><kwd>energy exchange</kwd><kwd>oxidative stress</kwd><kwd>deltamethrin</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">Lissenden, N.
