황금이 A549 세포주에서 $TNF-{\alpha}$ 및 IL-4로 유도된 chemokines에 미치는 영향

Effect of Scutellariae Radix Extract on the release of chemokines induced by $TNF-{\alpha}$ and IL-4 in A549 cells

Objectives : In the present study, the effect of Scutellariae radix on the release of RANTES, eotaxin, TARC induced by $TNF-{\alpha}$ and IL-4 in human bronchial epithelial cell(A549 cell) was examined. Scutellariae radix significantly inhibited the secretion of RANTES, eotaxin, TARC with a dose-dependant manner. Methods : In the experiment, to observe the toxity of the cell according to concentration of Scutellariae radix, MIT assay was carried out to examine cell viability. The effective dosage did not have the cytotoxicity on human bronchial epithelial cell in all control group excepting 50\;{\mu}g/ml$ concentration. Results : The above results shows Scutellariae radix inhibits the secretion of the release of RANTES, eotaxin, TARC on human bronchial epithelial cell(A549 cell). Conclusion : These results suggest that Scutellariae radix could be used as a prophylaxis and remedy of asthma induced by allergy and inflammatory reaction caused by several reasons.
