Наночастицы NiO (НЧ NiO) загрязняют воздух рабочей зоны при металлургическом производстве никеля и легированных сталей (во время их использования при электросварке). Токсичность НЧ NiO изучена экспериментально в ряде исследований, однако вопрос о механизмах их токсического действия не может считаться решенным и требует расширения базы экспериментальных данных.</p><p>Цель исследования — изучить токсическое действие наночастиц оксида никеля при хронической ингаляционной экспозиции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Аутбредные крысы-самки подвергались повторным низкоуровневым ингаляционным экспозициям к НЧ NiO 99,99% чистоты, размером 23±5 нм, по 4 часа в день, 5 раз в неделю, продолжительностью до 10 месяцев в установке типа «только нос» при концентрации 0,2±0,01 мг/м3. Для выбора этой концентрации предварительно был проведен пилотный эксперимент с 5-кратным воздействием при концентрации 1,00±0,12 мг/м3.</p></sec><sec><title>Результаты</title><p>Результаты. НЧ NiO как при краткосрочном, так и при хроническом ингаляционном поступлении оказывают влияние на перекисное окисление липидов, показатели красной крови, функцию печени и почек, окислительно-восстановительный баланс в организме; во все три срока хронического ингаляционного эксперимента вызывают активную реакцию альвеолярного фагоцитоза и обладают высокоцитотоксическим действием, судя по отношению нейтрофильных лейкоцитов к альвеолярным макрофагам и уровню ферментов в жидкости бронхоальвеолярного лаважа.</p></sec><sec><title>Выводы</title><p>Выводы. Наночастицы NiO при ингаляционном поступлении в концентрации 0,2 мг/м3 оказывают умеренное токсическое действие на организм экспериментальных животных. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Nanoparticles of NiO pollute air of workplace in metallurgic production of nickel and alloyed steel (during their use in electric welding). Toxicity of NiO nanoparticles was studied in some experiments, but mechanisms underlying their toxic eff ects are not understood and require wider base of experimental data.</p></sec><sec><title>Objective</title><p>Objective. To study toxic eff ects of NiO nanoparticles in chronic inhalation exposure.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Outbred female rats were subjected to repeated low-level inhalation exposure to NiO nanoparticles of 99.99% purity, measured 23±5 nm, 4 hours per day, 5 days per week, up to 10-month duration in an “only nose” device with concentration 0.2±0.01 mg/m3. To select this concentration, preliminary pilot experiment included 5-fold exposure with concentration 1.00±0.12 mg/m3.</p></sec><sec><title>Results</title><p> Results. NiO nanoparticles in short-term and chronic inhalation exposure aff ect lipids peroxidation, red blood parameters, liver and kidney functions, oxidation-reduction balance. All three terms of chronic inhalation experiment cause active alveolar phagocytosis reaction, and their high cytotoxicity is proved by relation of neutrophils to alveolar macrophages and by enzymes levels in bronchoalveolar lavage.</p></sec><sec><title>Conclusions</title><p>Conclusions. NiO nanoparticles if inhaled in concentration 0.2 mg/m3 cause moderate toxic eff ect in experimental animals.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ингаляционная экспозиция</kwd><kwd>наночастицы никеля</kwd><kwd>токсичность</kwd><kwd>цитотоксичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>inhalation exposure</kwd><kwd>nickel nanoparticles</kwd><kwd>toxicity</kwd><kwd>cytotoxicity</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">Ates M., Demir V., Arslan Z., Camas M., Celik F.
