title: [Effect of Oren-gedoku-to on changes in hexobarbital-induced sleeping time in chlorpromazine-treated mice].
abstract: The effects of Oren-gedoku-to on the hypnotic duration induced by hexobarbital, and on the change of this duration in chlorpromazine-treated mice were investigated. Single dose of Oren-gedoku-to (1.0 or 2.0 g/kg, p.o.) or chlorpromazine (10 mg/kg, p.o.) prolonged the hexobarbital hypnosis time. And the simultaneous dose of chlorpromazine (6.0 mg/kg, p.o.) and Orengedoku-to (1.0 g/kg, p.o.) indicated the equal effect for the administration of chlorpromazine (10.0 mg/kg, p.o.) alone. Although the mechanism of the action remains to be unknown, administration of Oren-gedoku-to in combination with chlorpromazine seems to be useful from the standpoint of alleviation of the side-effects caused by less dose.
