초록

Background and Objectives : The aim of this study was to investigate anti-inflammatory and anti-oxidant effects of Hyunggaeyungyo-tang(HYT) on RAW 264.7 cells. Material and Methods : Two types of experiments were implemented for this study: first, the experiment to study the anti-oxidant effect of HYT using riboflavin; second, in vitro experiment to investigate the suppression of NF-κB activation using RAW 264.7 cells (IκB kinase and induce nitric oxide synthase mRNA expression)Results : 1. The anti-oxidant effects of HYT was dose-dependantly increased. 2. The RAW 264.7cells were treated with LPS for 1 hours prior to the addition of indicated concentrations(0.4,-1.0㎎/㎖) of HYT, and the cells were further incubated for 24 hours. The LPS-induced IKK & iNOS mRNA expression were dose-dependantly decreased in HYT treated RAW 264.7cells. Conclusion : The results suggest that HYT is significantly effective in the treatment of inflammation through the suppression of NF-κB activation and iNOS production.
