Одним из важных этапов оценки безопасности наночастиц (НЧ) является анализ мутагенной активности, включающий оценку генных, хромосомных, геномных мутаций. </p></sec><sec><title>Материал и методы</title><p>Материал и методы. НЧ покрытого симетиконом диоксида титана (33,16 ± 16,7 нм, анатаз, 5–50000 мкг/мл), покрытого силикатом магнетита (10 нм, 0,92–575 мкг/мл), НЧ серебра, стабилизированные камедью аравийской (14 ± 0,2 нм, 5–50000 мкг/мл), нановолокно гидроксида алюминия (50–70 нм, 24–3000 мкг/мл) и многослойные углеродные нанотрубки (МУНТ «Таунит» с наружным диаметром 15–40 нм, внутренним диаметром 3–8 нм, длиной 2 и более мкм, 5–50000 мкг/мл). Параллельно в экспериментах оценивали мутагенную активность эквивалентных микрочастиц. Исследования проводили в тесте Эймса (Salmonella/микросомы), регистрирующем генные мутации разного механизма действия, в варианте с преинкубацией. Использован набор индикаторных штаммов Salmonella typhimurium: ТА 100 (мутации типа замены пар оснований), ТА 98 и ТА 97 (мутации типа сдвига рамки считывания генетического кода). Добавление во время эксперимента микросомальной активирующей смеси позволяет определять воздействие не только самих веществ, но и их метаболитов. </p></sec><sec><title>Результаты</title><p>Результаты. Во всех экспериментах кратность превышения среднего числа колоний ревертантов в опыте над таковым в контроле была менее 2, что свидетельствует об отсутствии мутагенного эффекта. </p></sec><sec><title>Заключение</title><p>Заключение. Исследованные наноматериалы, как и их микро-аналоги, в изученном диапазоне доз не индуцировали генные мутации в тесте Эймса на трёх штаммах Salmonella typhimurium в присутствии или без добавления микросомальной активирующей смеси.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. One of the important steps in assessing the nanoparticles (NP) safety is the analysis of mutagenic activity, including the evaluation of gene, chromosomal, and genomic mutations.</p></sec><sec><title>Material and methods</title><p>Material and methods. The purpose of this investigation is to study the ability of different NP aqueus suspensions and the same compounds in microforms to unduce gene mutations in Salmonella/microsome test (Ames test). </p><p>Anatase titanium dioxide NP coated with simethicone (33.16 ± 16.7 nm, 5-50000 μg/ml), magnetite NP coated with silicate (10 nm, 0.92-575 μg/ml), silver NP coated with аrabian gum (14 ± 0.2 nm, 5-50000 μg/ml), aluminum hydroxide nanofibres (50-70 nm, 24-3000 μg/ml) and multi-walled carbon nanotubes (Taunit MWСNTs, outer diameter 15-40 nm, inner diameter 3-8 nm, length 2 and more microns, 5-50000 μg/ml). In parallel, the mutagenic activity of equivalent microparticles was evaluated in experiments. Ames test (Salmonella/microsomes) registers gene mutations induced by a different mechanism of action, in the variant with preincubation. A set of Salmonella typhimurium indicator strains: TA 100 (base pair substitution mutations), TA 98 and TA 97 (mutations of the frameshift type of the genetic code) were used. Using addition the S9 microsomal activating mixture during the experiment makes it is possible to determine the effect not only of the substances themselves, but also of their metabolites.</p></sec><sec><title>Conclusion</title><p>Conclusion. The investigated nanomaterials as well as their micro analogs in the studied dose range did not induce gene mutations in the Ames test both in presence and absence microsomal activating mixture.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тест Эймса (Salmonella / микросомы)</kwd><kwd>мутагенность</kwd><kwd>наночастицы</kwd><kwd>наночастицы серебра</kwd><kwd>наночастицы диоксда титана</kwd><kwd>наночастицы магнетита</kwd><kwd>многостенные углеродные нанотрубки</kwd><kwd>нановолокно гидроксида алюминия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Ames test (Salmonella/microsome)</kwd><kwd>mutagenicity</kwd><kwd>nanoparticles</kwd><kwd>NP silver</kwd><kwd>NP titanium dioxide</kwd><kwd>magnetite nanoparticles</kwd><kwd>multi-walled carbon nanotubes</kwd><kwd>aluminum hydroxide nanofibers</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">Сычева Л.П., Журков В.С.
