Комплексное изучение состояния системы глутатиона и интенсивности процессов перекисного окисления липидов при отравлениях циклофосфаном в дозе 200 мг/кг массы. МАТЕРИАЛ И МЕТОДЫ. Спектрофотометрическое определение концентрации восстановленного глутатиона, сульфгидрильных групп белков, малонового диальдегида, диеновых конъюгат и активности глюкозо-6-фосфатдегидрогеназы, глутатионредуктазы, глутатионпероксидазы, глутатион-S-трансферазы, каталазы в тканях печени и почек 50 белых беспородных крыс. РЕЗУЛЬТАТЫ. Показано, что данная форма интоксикации сопровождается выраженными изменениями состояния системы глутатиона в тканях печени и почек отравленных животных (снижение содержания восстановленного глутатиона, нарушения активности глутатионредуктазы, глюкозо-6-фосфатдегидрогеназы, глутатионпероксидазы и глутатион-S-трансферазы). Обсуждены причины возникновения данных биохимических сдвигов, их межтканевые отличия и их роль в реализации цитотоксического действия циклофосфана. ЗАКЛЮЧЕНИЕ. Таким образом, установлена патогенетическая роль истощения функциональных возможностей системы глутатиона и активации свободнорадикальных процессов в реализации цитотоксического действия алкилирующих препаратов.</p></abstract><trans-abstract xml:lang="en"><p>THE AIM of the investigation was to carry out a complex study of the state of glutathione and intensity of lipid peroxidation processes in poisoning with cyclophosphamide in dose of 200 mg/kg of body mass. MATERIAL AND METHODS. Concentrations of reduced glutathione, sulfhydril groups of proteins, malonaldehyde, diene conjugates and activity of glucose-6-phosphatedehydrogenase, glutathione reductase, glutathione peroxidase, glutathione-S-transpherase, catalase were determined spectrophotometrically in the kidney and liver tissues of 50 white outbred rats. RESULTS. It was shown that this form of intoxication was followed by pronounced changes in the glutathione system in the liver and kidney tissues of poisoned animals (reduced content of reduced glutathione, impaired activity of glutathione reductase, glucose-6-phosphatedehydrogenase, glutathione reductase, glutathione-S-transferase).Causes of the appearance of the data of bio-chemical shifts, their interstitial distinctions and their role in realization of the cytotoxic action of cyclophosphamide were discussed. CONCLUSION. So, the pathogenetical role of exhaustion of the functional resources of the glutathione system was established as well as of activation of free radical processes in realization of the cytotoxic effects of alkilating preparations. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>циклофосфан</kwd><kwd>глутатион</kwd><kwd>глутатионпероксидаза</kwd><kwd>глутатионредуктаза</kwd><kwd>глутатионтрансфераза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cyclophosphamide</kwd><kwd>glutathione</kwd><kwd>glutathione peroxidase</kwd><kwd>glutathione reductase</kwd><kwd>glutathione transferase</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">Шулутко БИ.
