Increase in monoamine levels caused by emotional stress in mice brain regions is attentuated by Saiko-ka-ryukotsu-borei-to
Sasaki, K., Suzuki, K., Ueno, M., Takako, K., Yoshizaki, F.
The effect of Saiko-ka-ryukotsu-borei-to (SRBT) on the stress-induced increase of monoamines in brain regions was investigated in three mouse emotional stress models. Dopamine (DA) and 3,4-dihydroxy-phenyl acetic acid (DOPAC) contents were elevated significantly by electric shock stress, psychological stress and conditioned fear stress in thalamus, hypothalamus and amygdala. The DA and DOPAC levels were decreased by preadministration of SRBT (600 mg/kg, p.o.) in the last two models, but were not altered in electric shock stress. Therefore, this compound seems to be effective in stress involving emotional factors. These results indicate that SRBT affects the brain monoamine neurons leading to psychological change in mice.
