Abstract
Objective : Investigation of the anti-stress effects of Sihosogansan Methods : Passive avoidance test(PAT) was performed after applying immobilization stress in water to rats. Also, forced swimming test(FST) was performed to another rats and after FST, the degree of Tyrosine Hydroxylase(TH) expression was measured with immunohistochemical method in the regions of locus coeruleus(LC) and ventral tegmental area (VTA). Results : In the PAT after immobilization stress in water, response latency was significantly increased in the Sihosogansan(400mg/kg) group in comparison with the control group. In the FST, immobility was significantly decreased in the Sihosogansan groups (100mg/kg, 400mg/kg), comparing with the control group. Stress-induced TH increases were suppressed in the Sihosogansan groups (100mg/kg, 400mg/kg) at the LC and the VTA region respectively. Conclusion : Sihosogansan can improve memory ability of rats, reduce behavior of depression in rats, decrease TH-immunoreactive cells at the LC and VTA region in rat, and it may be concluded that Sihosogansan has significant effect in reducing stress.
