Objective : Asthma is known as chronic airway inflammatory disease. This inflammation is conducted by various inflammatory cells including eosihophil. Chemotaxis is one way that circulating inflammatory cells invade a specific lesion. This study examines the degree to which Lonicerae Flos inhibits eosinophil chemotaxis at pulmonary epithelium after allergic stimulation. Material and Methods : Water extracts of Lonicerae Flos and pulmonary epithelial cell lines A549(human type II-like epithelial cells) and human eosinophils were used. Cytotoxic effects of Lonicerae Flos via MTS assay were estimated, as well as the effects of Lonicerae Flos on chemokines from prestimulated A549 cells by sandwich ELISA and RT-PCR. Chemotaxis assay was conducted on prestimulated eosinophils treated with Lonicerae Flos. Result : In this study $TNF-{alpha}$ and IL-4, $IL-l{eta}$ were seen to induced the accumulation of chemokines mRNA in the pulmonary epithelial cell lines A549 in a dose-dependent manner. Chemokines were inhibited by Liripois Tuber in a dose-dependent manner and especially, IL-8 and ICAM-l were inhibited considerably at $100;{mu}g/ml$ concentration of Lonicerae Flos. The eosinophil migration is inhibited in high concentration of Lonicerae Flos in a dose-dependent manner. Conclusion : These findings indicate that the supression of the expression of chemokines can be accomplished by Lonicerae Flos treatment, raising the possibility that Lonicerae Flos might be of therapeutic value in diseases such as asthma.
