Силикоз остаётся одной из наиболее распространённых форм пневмокониозов среди профессиональных заболеваний лёгких, однако эффективные средства профилактики и лечения, направленные на ускорение удаления пылевых частиц из дыхательных путей, до сих пор недостаточно разработаны.</p><p>Цель исследования — оценить возможность использования лекарственных препаратов с антиоксидантными свойствами, доступных в аптечной сети, для стимуляции самоочищения лёгких от частиц кварцевой пыли в модели экспериментального силикоза у крыс.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование выполнено на белых крысах самцах линии Вистар, которым однократно интратрахеально вводили стандартный образец кварцевой пыли. Экспериментальные группы получали внутрибрюшинно этилметилгидроксипиридина сукцинат (ЭМГПС) или диметилоксобутилфосфонилдиметилат (ДМОБФДМ) в течение 4 недель, в положительном и отрицательном контроле использовали 0,9% раствор NaCl. По окончании эксперимента определяли мокрую и сухую массу лёгких, массовый лёгочный коэффициент, индекс сухого веса, коэффициент набухания, привес и относительное количество спонтанно удалённой из лёгких кварцевой пыли.</p></sec><sec><title>Результаты</title><p>Результаты. В группах с фиброзом мокрая и сухая масса лёгких достоверно превышали контроль, при этом отмечалась тенденция к снижению прироста массы тела. Относительное количество спонтанно удалённой кварцевой пыли в группе с ЭМГПС было достоверно выше, чем в положительном контроле, в то время как в группе с ДМОБФДМ его уровень не превышал контрольного.</p></sec><sec><title>Заключение</title><p>Заключение. ЭМГПС стимулирует самоочищение лёгких от частиц кварцевой пыли при экспериментальном силикозе у крыс, тогда как ДМОБФДМ в изученных условиях не проявил подобного эффекта. Полученные данные указывают на перспективность применения антиоксидантных препаратов системного действия для профилактики и терапии пылевых патологий лёгких, включая силикоз.</p></sec><sec><title>Этика</title><p>Этика.

Silicosis remains one of the most common forms of pneumoconiosis among occupational lung diseases. However, effective preventive and therapeutic measures aimed at accelerating the removal of dust particles from the respiratory tract remain underdeveloped.</p><p>The aim of this study was to evaluate the feasibility of drugs with antioxidant properties available in pharmacies to stimulate lung self-clearance from quartz dust particles in a rat experimental model of silicosis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The study was performed in male Wistar rats that received a single intratracheal instillation of a standard quartz dust sample. Experimental groups were treated intraperitoneally with ethylmethylhydroxypyridine succinate (EMHPS) or dimethyloxybutylphosphonyldimethylate (DMOBPDM) for 4 weeks; 0.9% saline was used in the positive and negative control groups. At the end of the experiment, wet and dry lung weight, lung mass coefficient, dry weight index, wet to dry ratio, body weight gain, and the relative amount of quartz dust spontaneously removed from the lungs were determined.</p></sec><sec><title>Results</title><p>Results. In the fibrotic groups, wet and dry lung weights were significantly higher than in controls, accompanied by a tendency toward reduced body weight gain. The relative amount of spontaneously removed quartz dust was significantly higher in the EMHPS group than in the positive control, whereas DMOBPDM did not increase dust clearance and yielded values did not exceed those in the control.</p></sec><sec><title>Conclusions</title><p>Conclusions. EMHPS enhances self clearance of quartz dust in experimental silicosis in rats, while DMOBPDM showed no such effect under the studied conditions. The results suggest the potential of systemic antioxidant drugs for the pathogenetic prevention and treatment of dust related lung diseases, including silicosis.</p></sec><sec><title>Contributions</title><p>Contributions:Tonshin A.A. — research concept and design, conducting experiments, collecting and processing experimental data, writing text;Makarov A.F. — concept and design of research, conducting experiments, preparation of literature data;Krikunov O.V. — conducting experiments;Bidevkina M.V. — concept and design of research, conducting experiments, preparation of literature data;Muravskaya M.P. — conducting experiments;Nikolaev I.M. — conducting experiments;Bonitenko E.Yu. — research concept and design, text writing, editing.</p></sec><sec><title>Funding</title><p>Funding.
