Исследование выполнено на 15 самках крыс Вистар. Модель постменопаузального остеопороза создавали двусторонней овариоэктомией со сроком наблюдения 56 суток. Терапию ресвератролом в экспериментальной группе проводили ежедневным внутрибрюшинным введением в дозе 2 мг/кг на протяжении такого же срока наблюдения. Проведены гистологическое исследование с компьютерным анализом изображений и морфометрией, абсорбционная рентгеновская денситометрия.</p></sec><sec><title>Результаты</title><p>Результаты. Двусторонняя овариоэктомия у экспериментальных животных - крыс Вистар, через 8 недель вместе с остеопоротическим поражением костных элементов приводит к увеличению объема костномозговой жировой ткани с гиперпластическим типом ожирения в бедренной кости и смешанным в большеберцовой. Ресвератрол в дозе 2 мг/кг, не влияя на диаметр адипоцитов, достоверно уменьшает их количество, снижая степень костномозгового ожирения.</p></sec><sec><title>Заключение</title><p>Заключение. Ресвератрол в дозе 2 мг/кг обладает выраженным фармакологическим действием на жировой компонент костного мозга бедренной и большеберцовой костей в модели постменопаузального остеопороза у крыс Wistar, снижая степень костномозгового ожирения. Это может отражать его влияние на коммитирование костномозговых стромальных предшественников с переключением преимущественно на остеобластическое направление дифференцировки, что объясняет его остеопротективный и регенераторный эффекты.</p></sec></abstract><trans-abstract xml:lang="en"><p>Objective - to investigate changes in the fatty tissue of the bone marrow of the proximal halves of the femur and tibia in experimental postmenopausal osteoporosis and its therapy with resveratrol.</p><sec><title>Materials and methods</title><p>Materials and methods. The study was performed on 15 female Wistar rats. A model of postmenopausal osteoporosis was created by bilateral ovariectomy with a follow-up period of 56 days. Resveratrol therapy in the experimental group was performed by daily intraperitoneal administration at a dose of 2 mg/ kg during the same follow-up period. Histological examination with computer analysis of images and morphometry, absorption X-ray densitometry were performed.</p></sec><sec><title>Results</title><p>Results. Bilateral ovariectomy in experimental Wistar rat animals 8 weeks after ovariectomy, together with osteoporotic lesion, leads to an increase in the volume of bone marrow adipose tissue with hyperplastic type of obesity in the femur and mixed in tibia. Resveratrol at a dose of 2 mg / kg, without affecting the diameter of adipocytes, significantly reduces their number, reducing the degree of bone marrow obesity.</p></sec><sec><title>Conclusion</title><p>Conclusion. Resveratrol at a dose of 2 mg/kg has a pronounced pharmacological effect on the fatty component of the femoral and tibial bone marrow in the Wistar rat model of postmenopausal osteoporosis, reducing the degree of bone marrow obesity. This may reflect its effect on the fixation of bone marrow stromal precursors with a switch mainly to the osteoblastic direction of differentiation, which explains its osteoprotective and regenerative effects.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>постменопаузальный остеопороз</kwd><kwd>ресвератрол</kwd><kwd>адипогенез</kwd><kwd>остеопротекция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>postmenopausal osteoporosis</kwd><kwd>resveratrol</kwd><kwd>adipogenesis</kwd><kwd>osteoprotection</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">Рожинская Л.Я., Луценко А.С.
