Моделирование гипокинезии осуществляли путем размещения тела животного специальном стакане и фиксации за хвост в течение 14 сут. Гематологические показатели определяли на гематологическом анализаторе, субфракционный состав сыворотки — методом лазерной корреляционной спектроскопии. После 14-суточной гипокинезии у мышей наблюдали значимое повышения числа нейтрофилов и снижение количества лимфоцитов. Также было показано значимое повышение количества циркулирующих эритроцитов. Субфракционный состав сыворотки крови мышей после гипокинезии отличался значимым увеличением вклада в светорассеяние частиц радиусом от 91,26 до 165,57 нм. Моделирование длительной гипокинезии на лабораторных животных позволит разработать подходы для профилактики и лечения последствий снижения двигательной активности.</p></abstract><trans-abstract xml:lang="en"><p>In this study, we evaluate the main hematological parameters and subfractional composition of mouse blood serum when modeling long-term hypokinesia. Hypokinesia was induced by placing the animal in a special glass and its fixation by the tail for 14 days. Hematological parameters were determined by a hematological analyzer; the subfractional composition of the serum were studied by laser correlation spectroscopy. Following 14-day hypokinesia, mice showed a significant increase in the number of neutrophils and  a decrease in the number of lymphocytes. A significant increase in the number of circulating erythrocytes was also detected. The subfractional composition of mouse blood serum after hypokinesia was distinguished by a significant increase in the contribution to light scattering of particles with a radius of 91.26 to 165.57 nm. Modeling long-term hypokinesia in laboratory animals is essential for developing approaches to the prevention and treatment of the consequences of decreased motor activity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипокинезия</kwd><kwd>показатели крови</kwd><kwd>лазерная корреляционная спектроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypokinesia</kwd><kwd>blood parameters</kwd><kwd>laser correlation spectroscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена в рамках государственного задания FGFU-2025-0003 «Оценка физиологического баланса организма при воздействии экстремальных факторов среды» ФГБНУ «НИИОПП».</funding-statement><funding-statement xml:lang="en">the work was carried out within the framework of the state assignment FGFU-2025-0003 “Assessment of the physiological balance of the body under the influence of extreme environmental factors” of the Research Institute of General Pathology and Pathophysiology.</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">Агеева В.А., Самусев Р.П.
