Японские ученые открыли снотворное, которое не даст проспать опасность
Исследователи из Университета Кагосимы в Японии обнаружили, что снотворные препараты из группы антагонистов рецептора орексина позволяют ввести организм в состояние сна и, в отличие от распространенных бензодиазепинов, не влияют на способность восприятия внешних стимулов. Подробная статья с исследованием опубликована в журнале Frontiers in Behavioural Neuroscience.
Ученые проанализировали влияние антагонистов рецептора орексина (нейропептида, отвечающего за состояние бодрствования и сна) на восприятие в состоянии сна. Исследование проводилось на группах лабораторных мышей. Одной группе вводили дозу двойного антагониста рецептора орексина DORA-22 (Dual Orexin Receptor Antagonist-22), а две другие группы испытуемых получали триазолам (бензодиазепин) и физраствор (контрольная группа).
В вовремя наблюдения контрольная группа проводила во сне 160 минут, в то время как в группе DORA-22 сон продолжался 221 минуту, а мыши с триазоламом спали 210 минут. Ученые исследовали способность животных проснуться при имитации случаев опасности. Для этого они раскачивали клетки, использовали запах помета хищника и снижали уровень кислорода.
Испытания показали, что животные, которые получали DORA-22, просыпались практически в такой же период времени, что и мыши из контрольной группы. Принимавшим триазолам мышам, чтобы проснуться, требовалось на несколько секунд больше. Результаты были одинаковы во всех случаях «опасности», за исключением гипоксии. Снижение уровня кислорода не показало влияния препаратов на скорость пробуждения.
Ученые считают, что подобное исследование может стать шагом к разработке нового типа снотворных препаратов, которые будут более безопасны и позволят не проспать громкие сигналы опасности. Например, такие как пожарная сигнализация или громкие крики.
