Так, непродолжительное лишение крысят грудного вскармливания в раннем постнатальном периоде приводит к МС в возрасте 4-6 мес. Однако эта модель МС требует оптимизации и детального изучения метаболических и гормональных показателей у взрослых животных. Цель работы состояла в изучении этих показателей у взрослых самцов крыс, лишённых грудного молока в возрасте 19-21 дней, что достигалось обработкой лактирующих самок бромокриптином. Взрослые самцы крыс имели повышенную массу тела и жировой ткани, нарушенную толерантность к глюкозе, инсулиновую резистентность, гиперлептинемию. У них были снижены уровни тестостерона, свободного тироксина и общего трийодтиронина при повышении уровня тиреотропного гормона. Тем самым, краткосрочное ограничение грудного вскармливания приводит у взрослых крыс к развитию МС и нарушению эндокринной регуляции.</p></abstract><trans-abstract xml:lang="en"><p>A short-term deprivation of rat pups from breastfeeding in the early postnatal period leads to MS at the age of 4-6 months. However, this neonatal MS model requires optimization and a detailed study into the metabolic and hormonal parameters of adult animals. The aim of the work was to study these parameters in adult male rats deprived of breast milk at the age of 19-21 days, which was achieved by treating lactating females with bromocriptine. Adult male rats showed an increased body weight and adipose tissue, impaired glucose tolerance, insulin resistance, and hyperleptinemia. These animals had reduced levels of testosterone, free thyroxine, and total triiodothyronine, with an increase in the thyroid-stimulating hormone. Thus, a short-term deprivation of breastfeeding in adult rats leads to the development of MS and endocrine dysregulations.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метаболический синдром</kwd><kwd>грудное вскармливание</kwd><kwd>инсулиновая резистентность</kwd><kwd>андрогенный дефицит</kwd><kwd>тиреоидная система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metabolic syndrome</kwd><kwd>breastfeeding</kwd><kwd>insulin resistance</kwd><kwd>androgen deficiency</kwd><kwd>thyroid system</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Грант на осуществление государственной поддержки НЦМУ «Павловский центр» (№ 075-15-2020-916).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>Grant for the implementation of state support to the NGWS “Pavlov Center” (No. 075-15-2020-916).</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">Derkach K.V., Bakhtyukov A.A., Romanova I.V., Zorina I.I., Bayunova L.V., Bondareva V.M., Morina I.Yu., Kumar Roy V., Shpakov A.O.
