The organ-specificity of the genotoxic effect of NDMA was revealed using the Comet assay. The most sensitive organs to the action of NDMA were kidneys and liver. DNA damage in liver cells of NDMA-treated animals at doses of 4.0 and 8.0 mg/kg, increased compared to control in 6.9 and 12.5 (р &lt; 0.001), and in kidney cells – in 8.1 and 14.2 times (р &lt; 0.001), respectively. NDMA also showed genotoxic activity in the reproductive cells of experimental animals, causing structural disorders of synaptonemal complexes in spermatocyte. In NDMA-treated animals at a dose of 2.0 mg/kg in acute and subacute studies, the level of spermatocytes with damaged synaptonemal complexes increased statistically significantly compared to control in 6.0 and 7.0 (р &lt; 0.05) times, respectively.</p></abstract><trans-abstract xml:lang="ru"><p>Установлено, что нитрозодиметиламин (НДМА) при остром и подостром воздействии на лабораторных мышей проявил генотоксические свойства. Выявлена органоспецифичность генотоксического действия НДМА с помощью метода ДНК-комет. Наиболее чувствительными органами к действию НДМА оказались почки и печень. Поврежденность ДНК в клетках печени животных, интоксицированных НДМА в дозах 4,0 и 8,0 мг/кг, по сравнению с контролем увеличилась в 6,9 и 12,5 (р &lt; 0,001), а в клетках почек — в 8,1 и 14,2 раза (р &lt; 0,001) соответственно. НДМА также проявил генотоксическую активность в половых клетках экспериментальных животных, вызывая нарушения структуры синаптонемных комплексов сперматоцитов. У животных, интоксицированных НДМА в дозе 2,0 мг/кг в остром и подостром опытах, уровень сперматоцитов с поврежденными синаптонемными комплексами статистически значимо возрос в 6,0 и 7,0 (р &lt; 0,05) раза соответственно по сравнению с контролем.</p></trans-abstract><kwd-group xml:lang="en"><kwd>N-nitrosodimethylamine (NDMA)</kwd><kwd>DNA strand breaks</kwd><kwd>synaptonemal complex</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нитрозодиметиламин (НДМА)</kwd><kwd>генотоксичность</kwd><kwd>метод ДНК-комет</kwd><kwd>разрывы ДНК</kwd><kwd>синаптонемный комплекс</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Работа выполнена в рамках проекта МОН РК ГР № 0112РК00580, руководитель проекта - Колумбаева С.Ж; Работа частично финансировалась Программой Президиума РАН «Живая природа», руководитель проекта - Абилев С.К., и грантом РФФИ № 16-04-01447а, руководитель гранта - Коломиец О.Л.</funding-statement><funding-statement xml:lang="ru">Работа выполнена в рамках проекта МОН РК ГР № 0112РК00580, руководитель проекта - Колумбаева С.Ж; работа частично финансировалась Программой Президиума РАН «Живая природа», руководитель проекта - Абилев С.К.; и грантом РФФИ № 16-04-01447а, руководитель гранта - Коломиец О.Л.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>1.
