Abstract

To study the anti-inflammatory effect of the combination of Epimedii Folium, Ligustri Lucidi Fructus and dexamethasone on asthma and its effect in inhibiting adverse reaction against hormone. Dexamethasone had been injected intraperitoneally into asthmatic model rats for 2 weeks, together with the oral administration of Epimedii Folium and Ligustri Lucidi Fructus. The contents of IL-4, INF-gamma, IL-5 and GCR in BALF, serum COR, plasma ACTH and hypothalamic CRH were observed. The combination of Epimedii Folium, Ligustri Lucidi Fructus and dexamethasone can significantly decrease the contents of IL-5 and IL-4 in BALF and ACTH and CRH content in plasma, increase the content of IFN-gamma and GCR in BALF and balance Th1/Th2. The combination of Epimedii Folium, Ligustri Lucidi Fructus and dexamethasone has a better anti-inflammatory effect on asthmatic model rats, and play a protective role in the pathway of endogenous dexamethasone.
