Свинец назван одним из приоритетных факторов среды обитания, высоко опасных для здоровья человека. В работе представлены результаты по изучению влияния ацетата свинца на двигательную активность потомства белых крыс, полученных от самцов с экспозицией ацетатом свинца, и эффекты генотоксичности.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Ацетат свинца крысы-самцы получали с питьевой водой в течение семи недель ежедневно из расчёта на одно животное — 60 мг/кг по свинцу. Полученное после спаривания с интактными самками потомство первого поколения (самцы) тестировали в «открытом поле» и определяли наличие ДНК-комет в половых клетках семенников и нервной ткани. Затем самцов подвергали экспозиции ацетатом свинца в той же дозе и после спаривания с интактными самками тестировали потомство второго поколения (самцов). </p><p>Цель исследования — изучить на беспородных крысах-самцах эффекты действия ацетата свинца на поведение потомства первых двух поколений и выявить генотоксический эффект.</p></sec><sec><title>Результаты</title><p>Результаты. При воздействии ацетата свинца на крыс-самцов трансгенерационный эффект проявлялся у животных двух поколений в виде изменений структуры поведения: снижение двигательной и исследовательской активности в первом поколении и повышение во втором поколении. Исследование методом ДНК-комет выявило повреждения ДНК в клетках головного мозга у потомства наряду с отсутствием такового в сперматозоидах.</p></sec><sec><title>Обсуждение</title><p>Обсуждение. Особенностью настоящих исследований явилось установление изменений адекватного видоспецифического поведения животных первого и второго поколений после воздействия ацетата свинца не на материнский, а на отцовский организм. Генотоксический эффект у потомства может быть обусловлен эпигенетическими нарушениями при формировании новых половых клеток во время воздействия свинца. </p></sec><sec><title>Заключение</title><p>Заключение. Воздействие ацетата свинца на взрослых особей-самцов белых крыс приводит к формированию нарушений двигательного и исследовательского компонента поведения, а также вызывает нарастание повреждённости ДНК в клетках головного мозга у потомства первого и второго поколений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Lead is one of the priority factors of the environment, highly hazardous to human health and causing the greatest concern due to the accumulation in the environment. The paper presents the results of the studying the influence of lead on genotoxicity and motor activity of posterity of white rats obtained from males exposed to lead acetate. </p><p>The aim of the study was to explore the effects of lead acetate action on the behavior of the offspring of the first two generations of male albino rats and to reveal the genotoxic effect.</p></sec><sec><title>Material and methods</title><p>Material and methods. Male albino rats received daily lead acetate with drinking water for 7 weeks (60 mg/kg). Obtained after mating with intact females first generation offspring (males) were tested in an “open field” and the presence of DNA comets in the sex cells of the testes and nervous tissue was determined. Then the males were exposed to lead acetate in the same dose and after mating with intact females, the male offspring of the second generation was tested according to a similar scheme. In all animals receiving a lead, its content in blood and testes was determined. </p></sec><sec><title>Results</title><p>Results. The results of the conducted research showed that under the influence of lead acetate on male rats, the transgenerational effect was manifested in animals of the first two generations in the form of changes in the structure of behavior having a different orientation — a decrease in motor and research activity in the first generation and an increase in the second generation. The DNA comet study revealed no DNA damage in sperm cells in animals exposed to lead neither in their offspring. Along with this, the results of the study of the degree of DNA damage in animal brain cells showed a significant increase in DNA damage in the first generation after the exposure to lead. </p></sec><sec><title>Discussion</title><p>Discussion. The effect of lead acetate on adult male albino rats leads to the formation of disturbances in motor and research component of behavior and also causes an increase in DNA damage in brain cells in first and second generations.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>свинец</kwd><kwd>белые крысы</kwd><kwd>потомство</kwd><kwd>двигательная активность</kwd><kwd>ДНК-кометы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>lead</kwd><kwd>white rats</kwd><kwd>the posterity of rats</kwd><kwd>motor activity</kwd><kwd>DNA comets</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">Budd P., Montgomery J., Evans J., Barreiro B.
