Влияние фармакологического прекондиционирования силденафилом и варденафилом на состояние микроциркуляторного русла в ишемизированной скелетной мышце

Abstract

Исследовано влияние фармакологического прекондиционирования силденафилом и варденафилом на состояние микроциркуляторного русла в ишемизированной скелетной мышце в сравнении с эффектом дистантного ишемического прекондиционирования. Определена роль индуцибельной NO-синтазы в реализации полученных эффектов. Ишемию моделировали на мышцах голени крыс. Состояние микроциркуляторного русла оценивали с помощью лазерной допплеровской флоуметрии и гистологического исследования. Выявлено, что силденафил и варденафил улучшают микроциркуляцию в ишемизированной мышце голени крыс за счет стимуляции неоангиогенеза. Полученные результаты позволяют проводить дальнейшие экспериментальные исследования возможности применения силденафила и варденафила для фармакологического прекондиционировния.

The influence of pharmacological preconditioning with sildenafil and vardenafil on condition of microvasculature in the ischemic skeletal muscle has been studied compared with the effect of distant ischemic preconditioning. The role of inducible NO-synthase has been defined in the implementation of the obtained effects. Ischemia was modeled on the leg muscles of rats. The state of microvasculature was assessed using laser doppler flowmetry and histological examination. It was found that sildenafil and vardenafil improve microcirculation in the ischemic leg muscles of rats by neovasculogenesis stimulation. The obtained results allow the possibility of further experimental studies of sildenafil and vardenafil for pharmacological preconditioning.
