title: Effect of saiko-ka-ryukotsu-borei-to on the stress-induced increase of serum corticosterone in mice.
abstract: The effect of Saiko-ka-ryukotsu-borei-to (SRBT) on the stress-induced enhancement of serum corticosterone in various stress models was investigated in mice. The serum corticosterone was elevated significantly by immobilized stress, forced-swim stress, electric-shock stress, psychological stress and conditioned-fear stress, respectively. The concentration in the last two models was decreased in a dose-dependent manner by pre-administration of SRBT (10, 60, 100, 600 and 1000 mg/kg, p.o.). Therefore, this action seems to be effective in stress involving emotional factors but ineffective in physical stress models. These results indicate that the anti-stress effect of SRBT is dependent strongly on the degree of psychological change compared with physical change in mice.
