Backgrounds : Two stress pathways, the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system, regulate immune system responses through release of corticosteroids, norepinephrine and epinephrine. respectively. These neuromediators act on immune cells via specific receptors on their surface to modulate the production of key regulatory cytokines.
Objectives : To evaluate the preventive effects of oriental medicine Hyeolbuchukyeo-tang (HC) on stress.
Methods : Mice were divided into three groups: nounal group, control group under immobilization stress and HC group which received Hyeolbuchukyeo-tang (HC) under immobilization stress. following sacrifice, their splenocytes were isolated and splenocyte surface markers were determined. The brains were removed and mRNA determined. In vivo, we separated RNA Iron cultured macrophages (RAW264.7).
Results : In our study, immune functions were decreased in stress due mainly to changes of various neuromediators, cytokines and macrophage activities, and the treatment of HC increased those expressions.
Conclusions : In summary, the present study documents the anti-stress effects of HC through stress-immune regulation.
