The functional activity of buccal epithelium largely determines the reactivity of the body and modulates the development of the pathological process. </italic></p><p><italic><bold>Material and methods. </bold>49 miners (mean age of 51.08 ± 0.51 years) with a history of chronic dust bronchitis, 55 miners (mean age of 50.96 ± 0.37 years), without occupational diseases, and 52 men of the control group (mean age of 50.61 ± 3.27 years) were examined with the use of micro-nuclear test to determine the frequency of prevalence rate of buccal epithelial cells with micronuclei, nuclear protrusion “bubble”, “broken egg”, “tongue”, as well as binuclear cells and double-nuclei cells.</italic></p><p><italic><bold>Results. </bold>In miners without occupational diseases, the frequency of the occurrence of cells with micronuclei and double-nuclei was 0.73 ± 0.99‰ and 4.25 ± 3.75‰, for the control group — 0.31 ± 0.53‰ (p = 0.0384) and 2.89±2.76‰ (p = 0.0195), respectively. Significant differences in miners with chronic dust bronchitis regarding the miners without occupational diseases were established on the following nuclear anomalies: the micronuclei (1.69 ± 1.29‰; 0.73 ± 0.99‰; p = 0.0384), protrusion “bubble” — (2.43 ± 2.08‰; 1.20 ± 1.51 ‰; p = 0.7175), the total frequency of protrusion (3.67±2.88‰; 1.81±2.01‰; p = 0.0001), binucleatedness (5.51 ± 4.28‰; 3.85 ± 4.01‰; p = 0.0129) and double-nuclei — (7.43 ± 4.45‰; 4.25 ± 3.75‰; p &lt; 0.0001). </italic></p><p><italic><bold>Discussion. </bold>No significant associations between nuclear anomalies with work experience and presence of harmful habits (smoking) were found in any of the examined groups. </italic></p><p><italic><bold>Conclusion. </bold>Thus, factors of underground mining production induce clastic and aneugenic effects; worsening hypoxia, related with the deterioration of respiration functions, the influence of inflammatory mediators and impaired redox homeostasis significantly increase the frequency of karyological damage in buccal epithelial cells.</italic></p></abstract><trans-abstract xml:lang="ru"><p><italic><bold>Введение. </bold>Угольная пыль является основным флогогенным фактором развития хронического пылевого бронхита у шахтёров. Функциональная активность буккального эпителия в значительной степени определяет реактивность организма и модулирует развитие патологического процесса.</italic></p><p><italic><bold>Материал и методы. </bold>У 49 шахтёров (средний возраст 51,08 ± 0,51 лет), имеющих в анамнезе хронический пылевой бронхит, 55 шахтёров (средний возраст 50,96 ± 0,37 лет), не имеющих профессиональных заболеваний, и 52 мужчин контрольной группы (средний возраст 50,61 ± 3,27 лет) с использованием микроядерного теста определены частоты встречаемости буккальных эпителиоцитов с микроядрами, ядерными протрузиями «пузырёк», «битое яйцо», «язык», а также двуядерных клеток и клеток со сдвоенным ядром.</italic></p><p><italic><bold>Результаты. </bold>Для группы шахтёров без профзаболеваний частота встречаемости клеток с микроядрами и сдвоенными ядрами составила 0,73 ± 0,99‰ и 4,25 ± 3,75‰, для контрольной группы 0,31 ± 0,53‰ (р = 0,0384) и 2,89 ± 2,76‰ (р = 0,0195) соответственно. Значимые отличия для группы шахтёров с хроническим пылевым бронхитом относительно шахтёров без профзаболеваний установлены по следующим ядерным аномалиям: микроядро (1,69 ± 1,29‰; 0,73 ± 0,99‰; р = 0,0384), протрузия «пузырёк» (2,43 ± 2,08‰; 1,20 ± 1,51 ‰; р = 0,7175), суммарная частота протрузий (3,67±2,88‰; 1,81±2,01‰; р = 0,0001), двуядерность (5,51 ± 4,28‰; 3,85 ± 4,01‰; р = 0,0129) и сдвоенное ядро (7,43 ± 4,45‰; 4,25 ± 3,75‰; р &lt; 0,0001).</italic></p><p><italic><bold>Обсуждение. </bold>Значимых ассоциаций уровня ядерных аномалий со стажем работы и наличием вредной привычки (курение) ни в одной из обследованных групп не выявлено.</italic></p><p><italic><bold>Заключение. </bold>Таким образом, производственные факторы подземной угледобычи индуцируют кластогенные и анеугенные эффекты; усугубление гипоксии, связанное с нарушением функций внешнего дыхания, воздействием медиаторов воспаления и нарушением редокс-гомеостаза значительно повышают частоту кариологических повреждений в буккальных эпителиоцитах.</italic></p></trans-abstract><kwd-group xml:lang="en"><kwd>coal</kwd><kwd>occupational diseases</kwd><kwd>chronic dusty bronchitis</kwd><kwd>DNA damage</kwd><kwd>micronucleus test on buccal epithelial cells</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>уголь</kwd><kwd>профессиональные заболевания</kwd><kwd>хронический пылевой бронхит</kwd><kwd>повреждения ДНК</kwd><kwd>микроядерный тест на буккальных эпителиоцитах</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Chen Y., Shan N., Huggins F.E., Huffman G.P.
