Крыс 1-й группы ( n = 10) подвергали равномерному облучению люминесцентными лампами ЛБ-40 (3500 лк, 48 ч). Крыс 2-й группы ( n = 20) подвергали однократному тотальному рентгеновскому облучению в дозах 10 и 15 Гр, а крыс 3-й группы ( n = 20) — комбинированному воздействию рентгеновского излучения и света в указанных параметрах с интервалом в 1 ч. Забор материала осуществляли сразу после окончания экспериментального воздействия. Установлено, что изменения зрительного нерва после ионизирующего (10, 15 Гр), светового и комбинированного воздействий проявляются деструкцией органелл, нейротрубочек и нейрофиламентов в осевых цилиндрах и демиелинизирующими изменениями. Количественный анализ показал, что реакции зрительного нерва при воздействии ионизирующей радиации проявляются в основном демиелинизацией оболочки и носят дозовую зависимость. Комбинация изучаемых факторов вызывает синергический эффект, который характеризуется увеличением числа нервных проводников с дегенеративными изменениями осевых цилиндров и миелиновых оболочек.</p></abstract><trans-abstract xml:lang="en"><p>Aimed at revealing the character of modifying influence of ionizing radiation on damages of visual nerve caused by bright light, three series of the experiment were performed. Rats of the first group (n = 10) were subjected to uniform irradiation by LB-40 luminescent lamps (3500 lk, 48 hours). Rats of the second group (n = 20) were subjected to unitary total X-ray radiation in a dozes of 10 and 15 Gr, and rats of the third group ( n = 20) were subjected to combined total influence of x-ray radiation and light of abovementioned parameters with an interval of one hour. The investigation showed that changes in visual nerve after ionizing (10, 15 Gr), light and combined influences are manifested in destruction of organelles, neuro-tubes and neuro-filamentes in axial cylinders and in demyelinizing changes. Quantitative analysis showed that reactions of visual nerve caused by the influence of ionizing radiation are resulted mainly in demyelinization of eye coat and are doze dependent. Combination of investigated factors causes synergic effect which is characterized by increased number of nervous conductors with degenerative changes of axial cylinders and mielinic coats.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>зрительный нерв</kwd><kwd>свет</kwd><kwd>рентгеновское излучение</kwd><kwd>visual nerve</kwd><kwd>light</kwd><kwd>X-ray radiation</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">Василенко И.Я.
