Object : This study investigates Jaeumganghwa-tang(JGT) has been used for the purpose of prevention and treatment of allergic inflammatory diseases. This study was to investigate the biological effects of JGT. Methods : Cytotoxcicity and inflammatory cytokines secretion with human mast cells(HMC-1) were examined. HMC-1 cells were stimulated with phorbol l2-myristate 13-acetate (PMA) and calcium ionophore A23l87. JGT by itself had no effect on cytotoxicity of HMC-1. The effects of JGT on the secretion of tumor necrosis factor-alpha(TNF-${\alpha}$) and interleukin(IL)-6 from HMC-1 were evaluated with enzyme-linked immunosorbent assay(ELISA). Result : It was found that JGT inhibited PMA plus A23187-induced TNF-${\alpha}$ and IL-6 secretion. JGT also inhibited the $NF-{\kappa}$B(p50) expression. Conclusion : These results suggest that JGT inhibits the secretion of inflammatory cytokines in HMC-1 cells through blockade of $NF-{\kappa}B$ activation. Taken together, these effects support a role for JGT as a therapeutic agent in treatment of allergic inflammatory diseases such as asthma.

Objectives In this study, the effects of Ja-eum-gang-hwa-tang (JGT) on the increase in airway epithelial mucosubstances of rats and ATP- or PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production and gene expression from human airway epithelial cells were investigated. Materials and Methods Hypersecretion of airway mucus was produced by exposure of $SO_2$ to rats for 3 weeks. The effect of orally-administered JGT for 2 weeks on increased epithelial mucosubstances from tracheal goblet cells of rats was assessed by using histopathological analysis after staining the epithelial tissue with Hematoxylin-eosin and PAS-alcian blue. Possible cytotoxicity of JGT was assessed by investigating the potential damage on kidneys and liver functions by measuring serum GOT/GPT activities and serum BUN concentration of rats and the body weight gain during experiment. Also, the effect of JGT on ATP- or PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production and gene expression from human airway epithelial cells (NCI-H292) were investigated. Confluent NCI-H292 cells were pretreated for 30 min in the presence of JGT and treated with ATP ($200{\mu}M$) or PMA ($10ng/ml$) or EGF ($25ng/ml$) or TNF-${\alpha}$ (0.2 nM) for 24 hrs to assess the effect of JGT both on ATP- or PMA- or EGF- or TNF-${\alpha}$-induced MUC5AC mucin production by using enzyme-linked immunosorbent assay (ELISA) and on gene expression by the same inducers using reverse transcription-polymerase chain reaction (RT-PCR). Results (1) JGT decreased the amount of intraepithelial mucosubstances of trachea of rats. (2) JGT did not show any renal and hepatic toxicities, and did not affect body weights either. (3) JGT significantly inhibited ATP-, PMA-, EGF-, and TNF-${\alpha}$-induced MUC5AC mucin productions from NCI-H292 cells. (4) JGT inhibited EGF-, and PMA-induced expression levels of MUC5AC gene in NCI-H292 cells. However, ATP- and TNF-${\alpha}$-induced MUC5AC gene expression levels were not affected in NCI-H292 cells. Conclusions The result from the present study suggests that JGT might control the production and gene expression of airway mucin observed in various respiratory diseases which accompanied by mucus hypersecretion. Also, JGT did not show liver toxicity or impact on kidney functions. The effect of JGT should be further studied by using animal experimental models which can show proper pathophysiology of airway diseases.

자음강화탕(Jaeumgangwha-tang, JGT)은 전통적인 한방처방으로, 만성 기관지염과 염증 질환 등을 치료하는데 사용된다. 자음강화탕을 10종의 균주로 발효한 후, HPLC-DAD를 이용하여 발효 전, 후의 자음강화탕에서 생물활성을 가지는 5-hydroxymethylfurfural(5-HMF), paeoniflorin, nodakenin, hesperidin, nodakenetin, palmatine, berberine, glycyrrhizin을 지표성분으로 설정하고 변화를 관찰하였다. 8종의 지표성분에 대하여 정성, 정량적인 동시분석을 수행하였고 머무름 시간($t_R$)과 UV 최대 흡수파장을 비교하였다. 이 결과 paeoniflorin이 6.95 mg/g으로 자음강화탕의 주성분으로 확인되었다. Lactobacillus fermentum KFRI 145으로 발효된 자음강화탕에서 nodakenetin의 함량이 $0.47{\pm}0.01mg/g$으로 관측되어 nodakenetin이 발효 후의 자음강화탕에서 발효 전보다 2,250% 증가한 것을 확인하였다. 또한 Lactobacillus acidophilus KFRI 162으로 발효된 자음강화탕에서 paeoniflorin과 hesperidin을 제외한 가장 많은 화합물들이 증가하는 것을 확인하였다.
