Abstract. In the present study, we investigated the effect of the Kampo medicme Yokukansan (YKS) on pentobarbital-induced sleep in group-housed and socially isolated mice. Socially isolated mice showed shorter sleeping time than the group-housed mice. YKS (300 mg/kg, p.o.) prolonged the pentobarbital-mduced sleeping time in socally isolated mice without affecting pentobarbtal sleep In group-housed mice. The prolongation of sleeping time by YKS was reversed by bcucul- Ine (3 mg/kg, ip.) and flumazenil (3 mg/kg, ip.), but not WAY100635. These findings suggest that the でABA。 - benzodiazepine receptor complex, but not 5-HTi。 receptors, 1s involved in the reversal effect of YKS on the decrease of pentobarbital sleep by socal isolation. eyの7の: sleep, soclal isolation, Yokukansan YKS), a Kampo medicine, is widely nia, Irritability, and screamng attacks. monstrated to improve behavioral and nptoms of dementia (BPSD), such as ltation, and irritability, in a randomized er, YKS improves sleep disturbance im ぐT) /う) 丁hnns 1c にak 人haf VIEKS bital-mduced sleep in group-housed and socially isolated mice.
