Abstract
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
