Ранее нами было показано, что гидрогель полигексаметиленгуанидин гидрохлорида проявляет выраженное ранозаживляющее действие в сравнении с препаратом на основе хлорамфеникола и метилурацила. При этом не были проведены исследования токсического воздействия гидрогеля на организм животных. Цель работы. В рамках данной работы была изучена острая токсичность гидрогеля полигексаметиленгуанидин гидрохлорида на лабораторных животных (белых мышах) при внутрижелудочном введении. Материалы и методы. Гидрогель полигексаметиленгуанидин гидрохлорида был получен путём сшивки концевых аминогрупп формальдегидом. Исследование острой токсичности проводилось (Р 1.2.3156-13, ГОСТ 32644-2014 и Руководство по проведению доклинических исследований лекарственных средств) в эксперименте на белых беспородных мышах при однократном добавлении в корм исследуемого вещества в различных дозах (1000, 3000, 5000 и 8000 мг/кг) с регистрацией показателей (внешний вид, поведение, состояние шёрстного покрова, потребление воды и пищи, экскреция, масса тела и её прирост) в течение 14 дней. После вывода животных из эксперимента производили вскрытие, макроскопическую оценку и взвешивание внутренних органов. Результаты. При введении исследуемого вещества в организм животных гибели в течение срока наблюдения (14 суток) не происходило. Внешний вид, поведение, состояние шёрстного покрова, потребление воды и пищи, экскреция подопытных животных в течение всего периода наблюдения не отличались от контрольной группы. Не наблюдалось статистически значимых изменений в приросте массы тела всех опытных групп относительно контрольной группы. Не представилось возможным определить полулетальную дозу для исследуемого соединения (ЛД50). Заключение. В связи с отсутствием летальных исходов в остром эксперименте не удалось определить полулетальную дозу для исследуемого соединения (ЛД50). Полученные результаты позволяют заключить, что данное вещество практически не токсично и может быть отнесено к V классу опасности по ГОСТ 32419-2013 (2000 &lt; LD50 ≤ 5000).</p></abstract><trans-abstract xml:lang="en"><p>Background. Previously, we have shown that the polyhexamethylene guanidine hydrochloride hydrogel exhibits a pronounced wound healing. At the same time, no studies of the toxic effect of the hydrogel on animals have been conducted. Aim of the research. In the framework of this work, the acute toxicity of the hydrogel polyhexamethylene guanidine hydrochloride was studied in laboratory animals with intragastric administration. Materials and methods. The polyhexamethylene guanidine hydrochloride hydrogel was obtained by crosslinking the amino end groups with formaldehyde. An acute toxicity study was carried out (P 1.2.3156-13, GOST 32644-2014 and the Guidelines for conducting preclinical studies of drugs) in an experiment on outbred mice with a single addition of the test substance in different doses (1000, 3000, 5000, 8000 mg/kg) with fixing indicators (appearance, behavior, condition of the body hair coat, water and food consumption, excretion, body weight and its growth) during 14 days. After the animals were withdrawn from the experiment, autopsy, macroscopic evaluation and weighing of the internal organs were performed. The results showed that with the introduction of the test substance into the animal organism, death during the observation period (14 days) did not occur. It was not possible to determine the semi-lethal dose for the test compound. Conclusion. The conducted studies allow us to conclude that this substance is practically non-toxic and can be classified as hazard class V. Further research will be directed to the formation of hydrogel compositions with medicinal substances.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полигексаметиленгуанидин гидрохлорид</kwd><kwd>гидрогель</kwd><kwd>ранозаживляющее действие</kwd><kwd>острая токсичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polyhexamethylene guanidine hydrochloride</kwd><kwd>hydrogel</kwd><kwd>acute toxicity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке гранта РФФИ № 18-315-00233 и государственного задания БИП СО РАН.</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">Wu DQ, Zhu J, Han H, Zhang JZ, Wu FF, Qin XH, et al.
