천사군자탕(喘四君子湯)과 수질(水蛭)(마황초(麻黃炒))가 인간 기관지상피세포의 IL-6, IL-16, GM-CSF 발현에 미치는 영향 = The Inhibitory Effects of Cheonsagunja-tang and Leech on the IL-6, IL-16, GM-CSF mRNA Level by Human Epithelial Cells

다국어 초록 (Multilingual Abstract)

Objectives : We aimed to identify the dose-dependent inhibitory effects of Cheonsagunja-tang(喘四君子湯), leech(Hirudo medicinalis/水蛭) roasted with Ephedrae Herba(麻黃) on the mRNA expression of IL-6, IL-16, GM-CSF involved in the asthma model. Methods : In the study BEAS-2B cell lines, human epithelial cells were used. These cells were stimulated with tumor necrosis factor(TNF)-${\alpha}$ for artificial inflammatory expression. ${\beta}$-actin messenger RNA(mRNA) was used by internal standard. After 24 hours of the Cheonsagunja-tang, leech-treatment, total cellular RNAs were collected treating RNA zol directly on the living cells. Then the transcriptional activities of IL-6, 16 and GM-CSF were measured by RT-PCR with electrophoresis. Results: In the Cheonsagunja-tang study, the mRNA expression of IL-6 showed 30% transcriptional inhibitory effect compared to the control group in the $100{\mu}l/ml$ category(p<0.005). In the IL-16, there was 26%, 31% and 31% transcriptional inhibitory effect compared to the control groups in the $4{\mu}l/ml$, $20{\mu}l/ml$ and $100{\mu}l/ml$ categories, respectively(p<0.05). In the GM-CSF, the experimental group had 56% transcriptional inhibitory effect compared to the control group in the $100{\mu}l/ml$ category(p<0.001). In other concentrations, there was no inhibitory effect. In the leech study, the mRNA expression of IL-6 showed 37% transcriptional inhibitory effect compared to the control group in the $100{\mu}l/ml$ category(p<0.001). In the IL-16, there was 63% and 67% transcriptional inhibitory effect compared to the control groups in the $20{\mu}/ml$ and $100{\mu}/ml$ categories, respectively(p<0.001). In the GM-CSF, there was 64% and 68% transcriptional inhibitory effect compared to the control groups in the $20{\mu}l/ml$ and $100{\mu}l/ml$ categories, respectively(p<0.001). In other concentrations, there was no inhibitory effect. Conclusions : This study shows that Cheonsagunja-tang and leech roasted with Ephedrae Herba have dose-dependent inhibitory effects on the mRNA expression of IL-6, IL-16 and GM-CSF in BEAS-2B cell lines, human epithelial cells.
