Проблема отсутствия эффективного и безопасного фармакологического средства смягчения последствий воздействия ионизирующего излучения становится все более актуальной. Ее решение затруднено по причине высокой химической токсичности всех известных по-настоящему эффективных радиопротекторов. Сейчас большое внимание уделяется изучению радиозащитных свойств так называемых природных соединений. Но в большинстве данных работ экспериментальная модель подвергалась единоразовому острому облучению. В то же время безопасный и эффективный радиозащитный препарат в условиях фракционированного облучения будет полезен при лучевой терапии онкологических заболеваний и при выполнении космических миссий, а также в условиях радиационного загрязнения территорий.</p></sec><sec><title>Цель</title><p>Цель. Сравнение радиозащитного эффекта медного хлорофиллина, рибоксина, также называемого инозином, и совместного применения глутатиона и аскорбиновой кислоты с таковым для эталонного российского радиопротектора индралина при фракционированном воздействии рентгеновским излучением.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Самцы мышей ICR (CD-1) были подвергнуты пяти ежедневным облучениям в дозе 2,5 Гр. В дни каждого облучения экспериментальным животным вводились хлорофиллин (20 мкг/г), индралин (50 мкг/г) в растворе винной кислоты или глутатион (250 мкг/г) и аскорбиновая кислота (150 мкг/г) перед облучением или рибоксин (200 мкг/г) после облучения. Выживаемость мышей оценивалась в течение 30 суток после последнего облучения.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Только применение рибоксина обеспечило выживаемость 10 % облученных животных, однако без статистически значимого повышения средней продолжительности жизни погибших особей относительно группы интактных мышей. Значимое повышение данного параметра обеспечило только использование индралина. Медный хлорофиллин не оказал радиозащитного действия. Возможно, применение безметаллических производных хлорофилла в будущем сможет оказать радиопротекторное действие в данных условиях. Совместное применение глутатиона и аскорбиновой кислоты привело к гибели 2 из 10 мышей в период облучений и введений препаратов, не обеспечив повышения выживаемости в период наблюдений.</p></sec><sec><title>Заключение</title><p>Заключение. Применение медного хлорофиллина и глутатиона с аскорбиновой кислотой не обеспечило повышения выживаемости и средней продолжительности жизни умерших мышей, подвергнутых облучению в дозе 12,5 Гр, распределенной на 5 фракций по 2,5 Гр. Применение индралина повысило только продолжительность жизни павших животных. Рибоксин способствовал выживанию 10 % соответствующей группы.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The problem of effectiveness and safe pharmacological means of reducing the consequences of exposure to the ionizing effect is becoming increasingly urgent. This solution is difficult due to the high chemical toxicity of all known modern effective radioprotectors. Nowadays, much attention is paid to the study of the radioprotective properties of the so-called effects. But in most of these works, the experimental model was subjected to a one-time acute irradiation. At the same time, a safe and effective radioprotective drug under conditions of fractionated irradiation will be useful in radiation therapy for oncological diseases and during space missions, as well as in conditions of radiation contamination of territories.</p></sec><sec><title>Aim</title><p>Aim. Comparison of the radioprotective effect of copper chlorophyllin, riboxin, also called inosine, and the combined use of glutathione and ascorbic acid with that of the reference Russian radioprotector indralin during fractionated exposure to X-ray radiation.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Male ICR (CD-1) mice were exposed to five daily irradiations of 2.5 Gy. On the days of each irradiation, experimental animals were administered chlorophyllin (20 μg/g), indralin (50 μg/g) in a solution of tartaric acid or glutathione (250 μg/g) and ascorbic acid (150 μg/g) before irradiation or riboxin (200 μg/g) after irradiation. The survival of mice was assessed within 30 days after the last irradiation.</p></sec><sec><title>Result and discussion</title><p>Result and discussion. Only the use of Riboxin ensured the survival of 10 % of irradiated animals, but without a statistically significant increase in the average life expectancy of dead animals relative to the group of intact mice. A significant increase in this parameter was provided only by the use of indralin. Copper chlorophyllin had no radioprotective effect. Perhaps the use of metal-free chlorophyll derivatives in the future will be able to have a radioprotective effect under these conditions. The combined use of glutathione and ascorbic acid led to the death of 2 out of 10 mice during the period of irradiation and drug administration, without providing an increase in survival during the observation period.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of copper chlorophyllin and glutathione with ascorbic acid did not increase the survival rate and average life expectancy of deceased mice irradiated at a dose of 12.5 Gy, distributed into 5 fractions of 2.5 Gy. The use of indralin only increased the life expectancy of dead animals. Riboxin contributed to the survival of 10 % of the corresponding group.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ионизирующее излучение</kwd><kwd>радиопротектор</kwd><kwd>фракционированное облучение</kwd><kwd>хлорофиллин</kwd><kwd>рибоксин</kwd><kwd>инозин</kwd><kwd>индралин</kwd><kwd>глутатион</kwd><kwd>аскорбиновая кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ionizing radiation</kwd><kwd>radioprotector</kwd><kwd>fractionated irradiation</kwd><kwd>chlorophyllin</kwd><kwd>riboxin</kwd><kwd>inosine</kwd><kwd>indralin</kwd><kwd>glutathione</kwd><kwd>ascorbic acid</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 23-24-00383, https://rscf.ru/project/23-24-00383/</funding-statement><funding-statement xml:lang="en">The study was supported by the Russian Science Foundation Grant No. 23-24-00383, https://rscf.ru/project/23-24-00383/</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Рождественский Л.
