С начала XXI века наночастицы серебра широко используются в различных отраслях индустрии, медицине и фармацевтике благодаря своим выраженным антибактериальным, противовирусным и фунгицидным свойствам. В связи с такой высокой востребованностью использования наночастиц серебра очень важно понимать сопутствующие потенциальные риски от их применения. </p></sec><sec><title>Материал и методы</title><p>Материал и методы. В работе изучали влияние длительного перорального введения коммерчески производимой биологически-активной добавки на основе наночастиц серебра размером 34 нм и стабилизированных поливинилпирролидоном в количестве 50 мкг/сутки/животное на когнитивные функции мышей линии C57Bl/6, а также их накопление в головном мозге методом инструментального нейтронно-активационного анализа. Используемая биологически-активная добавка рекомендуется людям для лечения желудочно-кишечных инфекций.</p></sec><sec><title>Результаты</title><p>Результаты. Обнаружено, что наночастицы серебра при сроке введения 180 сут ухудшают долговременную контекстуальную память, а также с течением времени содержание серебра в головном мозге повышается.</p></sec><sec><title>Заключение</title><p>Заключение. Нарушение когнитивных функций предположительно связано с накоплением серебра в головном мозге мышей. Это создаёт риск длительного перорального использования наночастиц серебра.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Since the beginning of the XXI century, silver nanoparticles have been widely used in various industries, medicine and pharmaceuticals due to their pronounced antibacterial, antiviral and fungicidal properties. In connection with such a high demand for the use of silver nanoparticles, it is very important to understand the associated potential risks from their use.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. In the course of the work, there has been a study of the effects of the long-term oral administration of a commercially produced dietary supplement based on silver nanoparticles with a size of 34 nm and stabilized with polyvinylpyrrolidone in an amount of 50 μg/day/animal on the cognitive functions of C57Bl/6 mice, as well as their accumulation in the brain by the method of instrumental neutron activation analysis. The dietary supplement used is recommended for people as a treatment for gastrointestinal infections. </p></sec><sec><title>Results</title><p>Results. It was found that after 180 days of administration, silver nanoparticles impair long-term contextual memory, and over time, the content of silver in the brain increases.</p></sec><sec><title>Conclusion</title><p>Conclusion. Presumably impaired cognitive function with accumulation of silver in the brains of mice. This poses the risk of prolonged oral use of the silver nanoparticles.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастица</kwd><kwd>наночастицы серебра</kwd><kwd>долговременная память</kwd><kwd>когнитивные функции</kwd><kwd>биокинетика</kwd><kwd>кинетика накопления</kwd><kwd>нейтронно-активационный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanoparticles</kwd><kwd>silver nanoparticles</kwd><kwd>long-term memory</kwd><kwd>cognitive functions</kwd><kwd>biokinetics</kwd><kwd>accumulation kinetics</kwd><kwd>neutron activation analysis</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">Щербаков А.Б., Корчак Г.И., Сурмашева Е.В., Скороход И.М., Михиенкова А.И.
