Purpose : This study is to examine the effects of Hwaganjeon water extract(HGJ) on immobilization-stress or cold-stress in BALB/C mice. Methods : We have Hwaganjeon water extract(HGJ) by freeze-dryer & melt it by a saline solution. We feed HGJ 500mg/Kg to 5mice, and add immobilization-stress by putting mice in plastic cylinder 10 hours, and add cold-stress by putting mice in $4^{\circ}C$ cold room 6 hours. Results : 1. HGJ decreased the serum level of histamine and corticosterone increased by immobilization-stress or cold-stress. HGJ inhibited the release of histamine from mast cells at the concentration of 1 mg/ml. 2. HGJ did not affect the cell viability of thymocytes decreased by immobilization-stress or cold-stress, but increased the cell viability of splenocytes decreased by immobilization-stress or cold-stress. 3. HGJ decreased the population of splenic $CD4^{+}$ and $CD8^{+}$cells increased by immobolization-stress or cold-stress. 4. HGJ enhanced the production of ${\gamma}$-interferon(IFN) and interleukin(IL)-2 decreased by immobilization-stress or cold-stress. Conclusion : These results indicate that HGJ may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of immune response.
