Objectives : HERBA EPHEDRAE (HE) has been used cough and asthma for long time in korea. In the present study, we examined the effect HE on the ovalbumin (OVA)-induced airway hyper-reactivity (AHR). Methods : To examine the effect of HE on AHR, mice were sensitized with 100 mg of OVA and 1mg of alum intraperitoneally on day 0 and 14. On day 28, mice were challenged on 3 consecutive days with 3% OVA and AHR was assessed 24 h after the last challenge. To examine severity of airway hyper-reactivity, we examined eosinophil population and cytokine production in bronchoaveloar lavage fluid(BALF) and stained with hematoxylin and eosin in lung. Results : HE potently inhibited the development of airway hyper-reactivity and also reduced the number of eosinophil during OVA-induced airway hyper-reactivity. HE also inhibited cytokines production such as IL-4, IL-5, IL-13 in BALF. Furthermore, HE inhibited proliferation of eosinophil in a dose dependent manner. Conclusions : These results suggest that HE may be beneficial oriental medicine for AHR.

Objective : Kumsoouyukkun-joen extract(KSE) has been used treating asthma for a long time in korea. In the present study, I examined the effects of KSE on the ovalbumin(OVA)-induced airway hyper-reactivity(AHR). Methods : To examine the effects of KSE on asthma, mice were sensitized with $100{\mu}g$ of OVA and 1 mg of aluminum potassium sulfate(Alum; Sigma)intraperitoneally on day 0 and 7. On day 14, mice were challenged on 3 consecutive days with 5% OVA and AHR was assessed 24 hrs after the last challenge. To examine severity of AHR, I examined eosinophil population and cytokine production in bronchoaveloar lavage fluid(BALF) and stained with hematoxylin and eosin in lung and also measured enhanced pause(Penh) in AHR from mice. Results and Conclusion : KSE potently inhibited the development of Penh and also reduced the number of eosinophil during OVA-induced AHR. KSE also inhibited cytokines production such as IL-4, IL-5 in BALF. Furthermore, KSE inhibited percentage of eosinophil in BALF. These results suggest that KSE may be beneficial oriental medicine for AHR.

Objective : Ephedra sinica (ES) has has been used as remedy of allergic diseases for a long time in Korea. In the present study, we investigated the anti-allergic effects of ES on experimental allergic asthma mouse model using ovalbumin (OVA). Methods : BALB/c mice were sensitized and challenged with 100 ug of OVA and 1 mg of aluminum potassium sulfate of 0.2 ml phosphate-buffered saline(PBS) intraperitoneally on day 1 and 15. mice were challenged on 3 consecutive days with 5% OVA and AHR was assessed 24 h after the last challenge. we examined the lung histology, airway hyper sensitivity, total inflammatory cell count in bronchoaveloar lavage fluid(BALF), Th2-associated cytokines production and IgE production. Results : ES potently inhibited the lung damage and the development of Penh. ES also reduced the number of BAL cells during OVA-induced allergic asthma. Furthermore, ES inhibited cytokines production such as IL-4, IL-13 productions, and IgE level of serum. Conclusion : These results suggest that ES may inhibit the production of IL-4, IL-13, IgE and infiltration of inflammatory cell and be beneficial oriental medicine for allergic asthma.

Objective : Glycyrrhiza uralensis Fisch (GUF) has been used as remedy of allergic diseases for a long time in Korea. In the present study, we investigated the anti-allergic effects of GUF on experimental allergic asthma mouse model using ovalbumin (OVA). Methods : BALB/c mice were sensitized and challenged with 100 ug of OVA and 1 mg of aluminum potassium sulfate of 0.2 ml phosphate-buffered saline (PBS) intraperitoneally on day 1 and 15. Mice were challenged on 3 consecutive days with 5% OVA and AHR was assessed 24 hrs after the last challenge. We examined total inflammatory cell number in bronchoaveloar lavage fluid (BALF), Th2-associated cytokine productions and lung histology. Results : GUF potently inhibited the development of airway hypersensitivity and also reduced the number of BAL cells during OVA-induced allergic asthma. GUF also inhibited cytokine productions such as IL-4, IL-13 in lung tissue. Furthermore, GUF treatment inhibited allergic airway inflammation. Conclusion : These results suggest that GUF may inhibit the production of IL-4, IL-13 and infiltration of inflammatory cell and be beneficial oriental medicine for allergic asthma.
