При оценке воздействия наносеребра на многие органы не изучено его влияние in vivo на семенники. Поэтому целью исследования являлась оценка воздействия in vivo наносеребра и сульфата серебра на семенник и определение корреляционных связей с цитогенетическими и цитотоксическими показателями. Нами проведена морфофункциональная сравнительная оценка in vivo двухнедельного перорального воздействия наносеребра и сульфата серебра в четырёх концентрациях (0,1; 5; 50 и 500 мг/л) наносеребра размером 14нм, стабилизированных аравийской камедью 1:7 по массе и четырёх аналогичных концентраций сульфата серебра на семенник мышей СВАхС57Вl/6 массой 25-35 г. 2 группы были контрольными: интактные мыши и мыши, получавшие с водой камедь. Результаты оценивали по 7 структурно-функциональным показателям. Показано, что воздействие как наночастиц серебра, так и сульфата серебра в концентрации 500 мг/л приводит к достоверному увеличению деструктурированных семенных канальцев, представленных канальцами с малодифференцированным и разряженным семенным эпителием, достоверному снижению числа клеток Лейдига и тенденцией к снижению количества сперматид, числа сперматозоидов и клеток Сертоли, что указывает на угнетение сперматогенеза в равной мере как для наночастиц серебра, так и сульфата серебра. Отмечена корреляционная связь между повышением числа сперматид с апоптозом и уменьшением числа канальцев со сперматозоидами, указывающая на механизм гонадототоксического действия.</p></abstract><trans-abstract xml:lang="en"><p>During the study of the effect of nanoparticles researches aimed at finding out the consequences of their influence on the structural and functional integrity of germ cells, which ensure genetic continuity must occupy the one of the central places. However, in the assessment of the impact of nanosilver on many organs its effect on the testicles in vivo was not studied. That’s why, the aim of the study was to assess in vivo the effect of nanosilver and silver sulfate on the testicle and to determine the correlation between cytogenetic and cytotoxic parameters. The comparative morphological in vivo evaluation of 2-weeks oral exposure of 4 concentrations (0.1; 5; 50 and 500 mg/l) of silver nanoparticles with size of 14.0 nm, stable arabian gum 1:7 by weight, and of 4 similar concentration of silver sulfate on the testicle of mice. The effect of silver nanoparticles and silver sulfate at the concentration of 500 mg/l is shown to lead to a significant increasing of destructured tubules with undifferentiated and depleted spermatic epithelium, significant decreasing in the number of Leydig cells and decreasing trend in the number of spermatidas, spermatozoons and Sertoli cells, which indicates to the inhibition of spermatogenesis in equal measure for both silver nanoparticles and silver sulfate. The pronounced correlation between the increase in the number of spermatidas with apoptosis and decreasing in the number of tubules with spermatozoon, indicating to the mechanism of gonadotoxic action.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наносеребро</kwd><kwd>сульфат серебра</kwd><kwd>семенник</kwd><kwd>токсичность</kwd><kwd>структурно-функциональные исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>silver nanoparticles</kwd><kwd>silver sulfate</kwd><kwd>testicle</kwd><kwd>mice</kwd><kwd>toxicity</kwd><kwd>structural-functional study</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">Филатов Б.Н., Бочарова Л.И., Клаучек В.В., Масленников А.А., Почепцев А.Я., Точилкина Л.П.
