В опытах на модели ишемии задней конечности у крыс изучить влияние агониста TrkA-рецепторов димерного дипептидного миметика 4-ой петли NGF соединения ГК-2 на микроциркуляцию в ишемизированной скелетной мышце.</p></sec><sec><title>Методы</title><p>Методы. Ишемию задней конечности вызывали у белых беспородных крыс самцов резекцией бедренной артерии. Соединение ГК-2 вводили в/б в дозе 1 мг/кг/сут в течение 14 дней. Показатели микроциркуляции регистрировали с помощью компьютерного лазерного анализатора «ЛАКК-ОП2». Регистрацию осуществляли одновременно в интактной и оперированной конечности до операции, через 1 и 14 суток после неё.</p></sec><sec><title>Результаты</title><p>Результаты. В условиях модели ишемии задней конечности показано, что соединение ГК-2 к 14-му дню после операции практически полностью восстанавливает показатель перфузии и коэффициент его вариации в ишемизированной мышце до уровня интактной контрлатеральной конечности.</p></sec><sec><title>Заключение</title><p>Заключение. Можно полагать, что противоишемическое действие соединения ГК-2 связано с восстановлением микроциркуляции в результате усиления процессов неоангиогенеза.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>The purpose of the study</title><p>The purpose of the study. In experiments on a hind limb ischemia model in rats, the effect of the TrkA-receptor agonist of the NGF 4th loop dimeric dipeptide mimetic compound GK-2 has been studied on microcirculation in ischemic skeletal muscle.</p></sec><sec><title>Methods</title><p>Methods. the Hind limb ischemia was caused in white male mongrel rats by the femoral artery resection. The compound GK-2 was administered intravenously (1 mg/kg/day during 14 days). Microcirculation parameters were recorded using a computer laser analyzer "LAKK-OP2". Registration was carried out simultaneously in the intact and operated limb before the operation, 1 and 14 days after it.</p></sec><sec><title>Results</title><p>Results. In the conditions of the hind limb ischemia model, it was shown that the compound GK-2 almost completely restored the perfusion index and its variation coefficient in the ischemic muscle to the intact contralateral limb level by the 14th day after surgery.</p></sec><sec><title>Conclusion</title><p>Conclusion. It can be assumed that the anti-ischemic effect of the compound GK-2 is associated with the restoration of microcirculation as a result of increased neoangiogenesis.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>NGF</kwd><kwd>ГК-2</kwd><kwd>микроциркуляция</kwd><kwd>показатель перфузии</kwd><kwd>коэффициент вариации</kwd><kwd>ишемия задней конечности</kwd><kwd>неоангиогенез</kwd></kwd-group><kwd-group xml:lang="en"><kwd>NGF</kwd><kwd>GK-2</kwd><kwd>microcirculation</kwd><kwd>perfusion index</kwd><kwd>variation coefficient</kwd><kwd>hind limb ischemia</kwd><kwd>neoangiogenesis</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">Ko SH, Bandyk DF.
