Исследование выполнено на 53 крысах линии Wistar, разделенных на 3 серии. В каждой серии моделировали остеомиелит бедренной кости путем прямой инокуляции в бедренный канал монобактериальной культуры (Staphylococcus aureus; MSSA, музейный штамм, или Pseudomonas aeruginosa, музейный штамм, или Escherichia coli, музейный штамм) в концентрации 1×108 КОЕ и установкой в зону инокуляции интрамедуллярного металлического имплантата. Животных каждой серии разделяли на 3 группы. В группе 1 дополнительных манипуляций с животными не проводили, в группах 2 и 3 на очаг инфекции воздействовали постоянным электрическим током (150 мАм, 1 минута) на 0, 2, 4 и 6, либо на 7, 9, 11 и 13 сутки. Срок эксперимента составлял 21 сутки. </p></sec><sec><title>Результаты</title><p>Результаты. У всех животных наблюдалась клиническая картина, характерная для остеомиелита, однако характер, степень выраженности и частота встречаемости признаков инфекционно-воспалительного процесса в группах были различными. </p></sec><sec><title>Заключение</title><p>Заключение. Воздействие электрическим током на ранних сроках после инфицирования оказало наиболее выраженный антимикробный эффект по отношению к P. aeruginosa при начале воздействия на 7 сутки после инфицирования. Менее выраженный эффект электровоздействия отмечен по отношению к S.aureus и E.coli при начале воздействия с первых суток после инфицирования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The aim of the research</title><p>The aim of the research. To study the features of the course of osteomyelitis in rats during the induction of an infectious and inflammatory process by various pathogens under conditions of early and delayed local exposure to direct electric current. </p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was carried out on 53 Wistar rats, divided into 3 series. In each series, osteomyelitis of the femur was modeled by direct inoculation into the femoral canal of a monobacterial culture (Staphylococcus aureus; MSSA, museum strain, or Pseudomonas aeruginosa, museum strain, or Escherichia coli, museum strain) at a concentration of 1 × 108 CFU and placing an intramedullary metal implant. The animals of each series were divided into 3 groups. In group 1, no additional manipulations were performed with the animals; in groups 2 and 3, the source of infection was exposed to a direct electric current (150 mAm, 1 minute) on days 0, 2, 4 and 6, or on days 7, 9, 11 and 13. The duration of the experiment was 21 days. </p></sec><sec><title>Results</title><p>Results. All animals had a clinical picture characteristic of osteomyelitis, but the nature, severity and frequency of occurrence of signs of the infectious-inflammatory process in the groups were different. </p></sec><sec><title>Conclusion</title><p>Conclusion. Exposure to electric current early after infection had the most pronounced antimicrobial effect against P. aeruginosa when exposure began on day 7 after infection. A less pronounced effect of electrical exposure was noted in relation to S.aureus and E.coli when exposure began on the first day after infection.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>остеомиелит</kwd><kwd>крыса</kwd><kwd>Staphylococcus aureus</kwd><kwd>Pseudomonas aeruginosa</kwd><kwd>Escherichia coli</kwd><kwd>постоянный электрический ток</kwd></kwd-group><kwd-group xml:lang="en"><kwd>osteomyelitis</kwd><kwd>rat</kwd><kwd>Staphylococcus aureus</kwd><kwd>Pseudomonas aeruginosa</kwd><kwd>Escherichia coli</kwd><kwd>direct electrical current</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в соответствии с планом научных исследований в рамках программы НИР государственного задания 2021–2023 гг.
