РИТМИЧЕСКИЕ ПРОЦЕССЫ АВТОРЕГУЛЯЦИИ ПОЧЕЧНОГО КРОВОТОКА И ИХ ВЗАИМОДЕЙСТВИЕ В ФОРМЕ МОДУЛЯЦИИ КОЛЕБАНИЙ

Авторегуляция почечного кровотока на уровне индивидуальных нефронов включает два взаимодействующих механизма, приводящих к генерации колебаний с разными временными масштабами: канальцево-гломерулярную обратную связь и миогенный отклик. На основе вейвлет-анализа экспериментальных данных в данной работе изучаются эффекты амплитудной и частотной модуляции миогенных колебаний ритмом канальцево-гломерулярной обратной связи. Отмечаются особенности нелинейных зависимостей девиации амплитуды и частоты модулируемого процесса от амплитуды модулирующих колебаний. Показывается, что эффекты модуляции существенно отличаются в норме и при гипертонии.
