The rats were received colorectal distension ( CRD) on hour 12, 24, 48 and 72 under REM sleep deprivation. The abdominal withdrawl reflex ( AWR) scores of the 3 groups were observed to measure their visceral sensitivity. 在REM睡眠剥夺的第12h、24h、48h、72h行结直肠扩张(CRD),观察大鼠的腹壁回撤反射(AWR)以测定内脏感觉功能。
Methods: The absence of the righting reflex was considered as the sleep onset and the duration of the loss of the righting reflex was recorded as the sleeping time. 方法:以翻正反射消失为睡眠开始的指标,至翻正反射恢复作为睡眠时间。
