The purpose of this research was to investigate the effects of Kamikwibitang water extract (KKT) on immobilization stress in C57BL/6J mice. KKT decreased the serum level of histamine and corticosterone increased by immobilization stress. In addition, KKT decreased the cell viability of thymocytes and enhanced the cell viability of splenocytes decreased by immobilization stress. Also, KKT decreased the viability of thymocytes and splenocytes in vitro. KKT decreased DNA fragmentation of splenocytes increased by immobilization stress. KKT decreased the population of thymic $CD4^+CD8^-$ cells increased by immobilization stress, and did not affect the population of $B220^+$ cells and the population of $Thy1^+$ cells changed by immobilization stress and enhanced the population of splenic $CD4^-CD8^+$ cells increased by immobilization stress. KKT enhanced the production of ${\gamma}-interferon$ and did not affect the production of interleukin-2 and interleukin-4 decreased by immobilization stress. Also, KKT decreased the phagocytic activity and the level of nitric oxide decreased by immobilization stress. These results indicate that KKT may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of specific-immune response.
