Тиосульфат натрия вводили внутрибрюшинно в дозе 0,1 г/кг через день в течение трех дней.РЕЗУЛЬТАТЫ: экспериментальные данные показывают, что применение тиосульфата натрия существенно снижает негативные последствия интоксикации, обусловленной введением глицерина животным. После введения препарата отмечалось восстановление поврежденных структур почечного эпителия, устранение признаков воспаления и окислительного стресса, а также возвращение показателей содержания креатинина и мочевины к норме. Полученные нами результаты демонстрируют увеличение уровней ионов натрия и хлора в плазме крови животных, получивших тиосульфат натрия, что отражает улучшение состояния почек и восстановления основных транспортных процессов.ЗАКЛЮЧЕНИЕ: таким образом, тиосульфат натрия благодаря своим антиоксидантным свойствам нейтрализует свободные радикалы и подавляет окислительный стресс, вызванный глицеролом, о чём свидетельствует изменение концентрации азота мочевины, креатинина в плазме и суточном диурезе и восстановление электролитного баланса в плазме и моче у крыс, получавших лечение.</p></abstract><trans-abstract xml:lang="en"><p>Being one of the key representatives of the group of biologically significant gases, along with nitrogen oxide and carbon monoxide, hydrogen sulfide demonstrates pronounced antioxidant properties, suppressing inflammatory processes and exerting a protective effect on tissues in various diseases.THE AIM: to study the effect of sodium thiosulfate on filtration and reabsorption processes in rats with acute renal injury (AKI).MATERIALS AND METHODS: AKI was modeled by a single intramuscular injection of 50% glycerol solution (10 ml/kg). Sodium thiosulfate was administered intraperitoneally at a dose of 0.1 g/kg every other day for three days.RESULTS: Experimental data show that the use of sodium thiosulfate significantly reduces the negative effects of intoxication caused by the administration of glycerol to animals. After administration of the drug, the damaged structures of the renal epithelium were restored, signs of inflammation and oxidative stress were eliminated, and creatinine and urea levels returned to normal. Our results demonstrate an increase in the levels of sodium and chlorine ions in the blood plasma of animals treated with sodium thiosulfate, which reflects an improvement in kidney condition and restoration of the main transport processes.CONCLUSION: Thus, sodium thiosulfate, due to its antioxidant properties, neutralizes free radicals and suppresses oxidative stress caused by glycerol, as evidenced by changes in the concentration of urea nitrogen, creatinine in plasma and daily diuresis and restoration of electrolyte balance in plasma and urine in rats treated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>острое повреждение почек</kwd><kwd>глицерол</kwd><kwd>тиосульфат натрия</kwd><kwd>креатинин</kwd><kwd>мочевина</kwd><kwd>натрий</kwd><kwd>хлориды</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute renal injury</kwd><kwd>glycerol</kwd><kwd>sodium thiosulfate</kwd><kwd>creatinine</kwd><kwd>urea</kwd><kwd>sodium</kwd><kwd>chlorides</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">GBD 2023 Kidney Failure with Replacement Therapy Collaborators.
