Objective : We aimed to identify the dose-dependent inhibitory effects of Sabaek-san(瀉白散) and Sabaeksan plus Sasam(Adenophorae Radix) 瀉白散加沙蔘) on the mRNA expressions of Interleukin(IL)-6, IL-8 and granulocyte macrophage colony stimulating factor(GM-CSF) involved in the asthma model.
Materials and Methods : Through this study, BEAS-2B cell lines, human epithelial cells were used. These cells were stimulated by tumor necrosis factor(TNF)-{alpha}, IL-1{beta} and histamine for artificial inflammatory expression. {beta}-action messenger RNA(mRNA) was used for standards. After each 24hours of Sabaeksan and Sabaeksan plus Sasam treatment, total cellular RNAs were collected by treating RNA zol directly on living cells, Then the transcriptional activities of IL-6, 8 and GM-CSF were measured by RT-PCR with electrophoresis,
Results : The mRNA expressions of IL-6 are significantly inhibited compared to those of controlled group at 40 and 100ug/ml of Sabaeksan extract and 100{mu}g/ml of Sabaeksan plus Sasam extract (p<0.05). The mRNA expressions of IL-8 are significantly inhibited compared to that of controlled group at 2.40 and 100 ug/ml of Sabaeksan extract and 40.100{mu}g/ml of Sabaeksan plus Sasam extract(p<0.05) THe mRNA expressions of GM-CSF are significantly inhibited compared to those of the controlled group at 100{mu}g/ml of Sabaeksan extract adn 40.100{mu}g/ml of Sabaeksan plus Sasam extract.(p<0.05)
Conclusions : This study shows that Sabaeksan and Sabaeksan plus Sasam have dose-dependent inhibitory effects on the mRNA expressions of IL-6, IL-8 and GM-CSF in human epithelial cells. Therefore, these types of herb medicine may inhibit the inflammatory process of asthma. Advanced studies are required to investigate the mechanisms of inhibition by herb medicine in the asthma model.
