Активное использование в различных сферах хозяйственной деятельности, крупнотоннажный характер производства и наличие данных о токсичности обусловливают актуальность изучения эффектов наночастиц оксида меди (II) (НЧ CuO) на организм при ингаляционном воздействии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Установлены размер, площадь поверхности и объём пор НЧ CuO. Проведены изучение и оценка биохимических и гематологических параметров крови, степень бионакопления наноматериала, патоморфологических изменений органов крыс, экспонированных НЧ CuO. Исследования проведены в сравнении с микроразмерным аналогом (МЧ CuO).</p></sec><sec><title>Результаты</title><p>Результаты. Размер НЧ CuO в составе нативного порошка меньше, чем у МЧ CuO, в 305 раз. Площадь поверхности и объём пор больше в 9,61 и 9,33 раза соответственно. После экспозиции НЧ CuO в крови крыс относительно контроля увеличены уровни активности аланинаминотрансферазы (АЛТ), аспартатаминотрасферазы (АСТ), щелочной фосфатазы (ЩФ), гамма-глутамилтранспептидазы (γ-ГТ), лактатдегидрогеназы (ЛДГ), амилазы, антиоксидантной активности плазмы (АОА), малонового диальдегида (МДА), концентрация С-реактивного белка (СРБ) в 1,49–2,23 раза, снижено содержание мочевины в 1,41 раза; увеличены относительное число эозинофилов, количество лейкоцитов, относительная ширина распределения эритроцитов (RDW) в 1,31–5,39 раза, снижено относительное число сегментоядерных нейтрофилов в 1,37 и моноцитов в 1,42 раза. Действие НЧ в сравнении с МЧ более выражено по повышению активности АЛТ, АСТ, ЛДГ, МДА, концентрации СРБ в 1,25–1,68 раза и по снижению концентрации мочевины в 1,21 раза; по повышению доли эозинофилов в 2,37 и количества лейкоцитов в 1,61 раза. Концентрация меди при действии НЧ увеличивается относительно контроля в лёгких, печени, желудке, кишечнике и почках в 1,59–6,99 раза. Степень бионакопления наночастиц больше, чем у микрочастиц, в лёгких, печени, желудке, почках в 1,2–2,12 раза. Функциональные и патоморфологические изменения, вызванные НЧ CuO, более выражены в лёгких, желудке, тонком кишечнике в сравнении с микрочастицами.</p></sec><sec><title>Заключение</title><p>Заключение. Подтверждено, что исследуемые частицы CuO являются наноматериалом. Обладают более выраженным бионакоплением и токсическим действием относительно микродисперсного аналога.</p></sec><sec><title>Участие авторов</title><p>Участие авторов: </p></sec><sec><title>Зайцева Н</title><p>Зайцева Н.В. — концепция и дизайн исследования, статистическая обработка материала, редактирование;</p></sec><sec><title>Землянова М</title><p>Землянова М.А. — концепция и дизайн исследования, обработка материала, написание текста;</p></sec><sec><title>Степанков М</title><p>Степанков М.С. — сбор материала, написание текста;</p></sec><sec><title>Игнатова А</title><p>Игнатова А.М., Николаева А.Е. — обработка материала.</p><p>Все соавторы — утверждение окончательного варианта статьи, ответственность за целостность всех частей статьи.</p></sec><sec><title>Конфликт интересов</title><p>Конфликт интересов.

Active use in various spheres of economic activity, large-scale production and the availability of data on toxicity determine the relevance of studying the effects of copper (II) oxide nanoparticles (CuO NPs) on the body during inhalation exposure.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. The size, surface area, and pore volume of CuO NPs were determined. The study and assessment of biochemical and hematological parameters of blood, the degree of bioaccumulation of nanomaterial, pathomorphological changes in organs of rats exposed to CuO NPs were carried out. The studies were carried out in comparison with a microsized analogue (CuO MPs).</p></sec><sec><title>Results</title><p>Results. The size of CuO NPs in the composition of the native powder is 305.00 times less than that of CuO MPs. The surface area and pore volume are 9.61 and 9.33 times larger, respectively. After exposure to CuO NPs in the blood of rats relative to the control, the levels of activity of ALT, AST, ALP, GGT, LDH, amylase, AOA, MDA and the concentration of CRP increased by 1.49-2.23 times, the content of urea decreased by 1.41 times; relative number of eosinophils, leukocyte count, RDW by 1.31-5.39 times increased, relative number of segmented neutrophils decreased by 1.37 and monocytes by 1.42 times. The effect of NPs, in comparison with MPs, is more pronounced in increasing the activity of ALT, AST, LDH, MDA and the concentration of CRP by 1.25-1.68 times and in reducing the concentration of urea by 1.21 times; in increase the relative number of eosinophils by 2.37 and the count of leukocytes by 1.61 times. The concentration of copper under the action of NPs increases relative to the control in the lungs, liver, stomach, intestines and kidneys by 1.59-6.99 times. The degree of bioaccumulation of nanoparticles is 1.20-2.12 times higher than that of microparticles in the lungs, liver, stomach, and kidneys.</p></sec><sec><title>Conclusion</title><p>Conclusion. Functional and pathomorphological changes caused by CuO NPs are more pronounced in the lungs, stomach, and small intestine in comparison with microparticles. It was confirmed that the studied CuO particles are nanomaterials. They have a more pronounced bioaccumulation and toxic effect relative to the microdispersed analogue.</p></sec><sec><title>Contribution</title><p>Contribution: </p></sec><sec><title>Zaitseva N</title><p>Zaitseva N.V. — the concept and design of the study, statistical processing of the material, editing;</p></sec><sec><title>Zemlyanova M</title><p>Zemlyanova M.A. — the concept and design of the study, processing of the material, writing the text;</p></sec><sec><title>Stepankov M</title><p>Stepankov M.S. — collection of material, writing the text;</p></sec><sec><title>Ignatova A</title><p>Ignatova A.M., Nikolaeva A.E. — processing of the material.</p><p>All authors are responsible for the integrity of all parts of the manuscript and approval of the manuscript final version.</p></sec><sec><title>Conflict of interest</title><p>Conflict of interest.
