Objective : Banhahubak-tang is indicated for globus hystericus, marked by a subjective sensation as if something stuffed in the throat, chest distress, cough or vomiting, greasy whitish, taut and smooth pulse. In this study, the effects of Banhahubak-Tang extract (BHTe) were tested for anti-stress action. Methods : BHTe was extracted by pure water using electronic extractor and then fed to ICR male mice ($20{\pm}2g$) orally with the dose of 100mg/kg/day for five days. Mice were exposed to sociopsychological stress by restraining and seeing foot shock stressed mice for one hour for five days. Results : BHTe administered group showed a tendency of decreasing of serum corticosterone secretion when compared with control group, and BHTe administration also significantly up-regulated noradrenaline secretions in the dorsal cortex of brain. Lipid peroxidation of the brain tissues of mice were tested by measuring malondialdehyde, but BHTe showed no significant change. The elevated plus-maze test was designed to detect the effect of anxiolytic drugs, and BHTe administered group showed a significant increase of latency time. Conclusions : These results suggest that BHTe can effectively rid the psychological stress and it's related diseases.

Objectives: This study is designed to investigate the effects of Banhahubak-Tang Extract (BHTe) on stress. Methos: BHTe was fed to ICR male mice ($20{\pm}2g$) 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.
