Chemokines are important for the recruitment of leukocytes, which is essential in host defense to the sites of infection. The thymus and activation-regulated chemokine (TARC) is a CC chemokine which potentially plays a role via a paracrine mechanism in the development of allergic respiratory diseases. Objectives : The objective of this study is to investigate the effect of Ephedrae Herba Herbal Acupuncture Solution(EHS) on the secretion of TARC of human bronchial epithelial cell. Methods : Enzyme-linked immunosorbent assay (ELISA) was performed to detect the secretion of TARC. The cytotoxicity was measured by MTT assay. Results : EHS significantly inhibited the secretion of TARC with a dose-dependant manner. The effective dosage did not have the cytotoxicity on human bronchial epithelial cell. Conclusion : Results of our study imply that EHS would play an important role in modulation of TARC in human bronchial epithelial cells by MTT assay.
