В то же время механизмы, обусловливающие возникновение патофизиологических процессов при ожирении, изучены недостаточно, а изучение непосредственного влияния периваскулярной жировой ткани на сократительную деятельность сосудов начато относительно недавно. В связи с этим работа проведена с целью исследования сократительной активности аорты крысы в норме и при метаболических нарушениях, вызванных диетой. Работа выполнена в лаборатории физиологии кровеносной и лимфатических систем Института физиологии им. И.П. Павлова РАН. Моделирование ожирения у крыс осуществляли с помощью диеты кафетерия, анализ параметров сократительной деятельности проводили с использованием результатов проволочной миографии изолированных сосудов. Установлено, что при ожирении происходит потеря антисократительного влияния периваскулярной жировой ткани на гладкие мышцы аорты, препятствующего развитию повышенной вазоконстрикции в норме. Выявление существующих причинно-следственных связей между жировой тканью и состоянием сосудистой стенки, определяющей адекватное кровоснабжение тканей, сможет явиться основой новых подходов решения проблемы, связанной с разработкой способов снижения негативного эффекта ожирения.</p></abstract><trans-abstract xml:lang="en"><p>Obesity is one of the major risk factors for the development of cardiovascular diseases, which currently account for a significant proportion of the total number of pathologies and are one of the main causes of mortality. At the same time, the mechanisms leading to the occurrence of pathophysiological processes in obesity are poorly studied, and the study of the direct influence of perivascular adipose tissue (PVAT) on vascular contractile activity has only recently begun. In this regard, the present study was undertaken to investigate the contractile activity of the rat aorta in normals and in diet-induced metabolic disorders. The work was carried out at the Laboratory of Physiology of Circulatory and Lymphatic Systems of Pavlov Institute of Physiology of the Russian Academy of Sciences. The modelling of obesity in rats was carried out using a cafeteria diet, and the analysis of contractile activity parameters was carried out using the results of wire myography of isolated vessels. It was found that obesity results in the loss of the anticontractile effect of perivascular adipose tissue on the aortic smooth muscle preventing the development of increased vasoconstriction in normals. Identifying the existing cause-effect relationships between adipose tissue and the state of the vessel wall, which determines the adequate blood supply to the tissues, may provide the basis for new approaches to solving the problem of developing ways to reduce the negative effects of obesity.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аорта</kwd><kwd>ожирение</kwd><kwd>периваскулярная жировая ткань</kwd><kwd>диета кафетерия</kwd><kwd>крыса</kwd><kwd>вазоконстрикция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aorta</kwd><kwd>obesity</kwd><kwd>perivascular adipose tissue</kwd><kwd>cafeteria diet</kwd><kwd>rat</kwd><kwd>vasoconstriction</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена по результатам доклада на Международной научно-практической конференции «Актуальные вопросы физиологии животных», посвященной 155-летию со дня образования кафедры физиологии животных в РГАУ-МСХА имени К.А.
