Abstract
Objectives: This study is designed to investigate the effects of Banhahubak-Tang Extract (BHTe) on stress. Methos: BHTe was fed to ICR male mice (<TEX>$20{\pm}2g$</TEX>) orally with the dose of 100 mg/kg/day for five days. Mice were then exposed to sociopsychological stress by observing foot shock stressed mice for one hour for five days while restrained. Results: 1) The BHTe-administered group showed a tendency of decreasing of serum corticosterone secretion compared with the control group. 2) The BHTe-administered group showed an increase in noradrenalin secretions in the dorsal cortex of the brain, but it was not significant. 3) BHTe administration had no effect on the brain level of lipid peroxidation. 4) BHTe administration decreased the serum level of lipid peroxidation. 5) BHTe administration decreased the Cu,Zn-SOD in the brain. 6) BHTe administration had no effect on catalase activity in the brain. 7) BHTe administration had no effect on the brain level of GSH. 8) BHTe administration increased the serum level of DPPH free radical scavenging activity, but not significantly enough to make a comparison with BHT. 9) The elevated plus-maze test is designed to detect the effect of anxiolytic drugs. The BHTe group showed a significant increase in latency time. Conclusions: These results suggest that BHTe can effectively rid the subject of the effects of sociopsychological stress.
