Background : Recently, so many people are suffered from the allergic or auto-immune disease, and the representative disease is just Allergic Asthma. It is because human immune function has been decreased. Many treatments were done to treat this disease, and many methods were studied to increase immune function and to suppress the asthma. But, the effect of asthma-suppression and improvement of immune response of EH-HA(Ephedrae Herba Herbal Acupuncture) has not been studied in detail. To study the effects of EH-HA, we injected EH-HA at Joksamni(ST36) of C57BL/6 mice. Objectives : The purpose of this study is to investigate the effect of asthma-suppression and improvement of immune response of EH-HA(Ephedrae Herba Herbal Acupuncture). EH-HA was done at Joksamni(ST36) of the mice with ovalbumin-induced asthma. Methods : C57BL/6 mice were sensitized and challenged with OVA(ovalbumin) for 12 weeks. Two experimental groups were treated with different concentrations(1%, 0.1%) of EH-HA at Joksamni(ST36) for the later 8 weeks(3times/week). Results : 1. The lung weight of the group treated with EH-HA decreased significantly compared with that of control group. 2. The total cells in lung, total leukocytes and eosinophils in BALF of the group treated with EH-HA decreased significantly compared with those of control group. 3. Eosinophils in BALF of the group treated with EH-HA in photomicrographs decreased significantly compared with those of control group. 4. The concentrations of IL-13, IgE, IL-4 in serum and IL-4 in BALF of the group treated with EH-HA decreased significantly compared with those of control group. 5. The numbers of $Gr-1^+/CD11b^+;cells,;CD3e^-/CCR3^+;cells,;CD4^+;cells,;CD8^+;cells,;CD3e^+/CD69^+;cells;and;IgE^+/B220^+;cells$ in lung of the group treated with EH-HA decreased significantly compared with those of control group. 6. In RT-PCR, the mRNA expression of IL-4, IL-5 and IL-13 in the group treated with EH-HA decreased compared with those of control group. Conclusion : These results suggested that EH-HA at Joksamni(ST36) in C57BL/6mice may be effective to OVA-induced asthma of C57BL/6 mice.
