The author investigated whether Chwiyeon-tang(PC), Haengso-tang(PH), Jawanchihyo-san(PJ) and Gamisocheongryong-tang(PS) significantly affect both PMA-induced mucin production and MUC5AC gene expression in airway epithelial cells and sulfur-dioxide-induced airway goblet cell hyperplasia and mucus hypersecretion animal model using rat. Possible cytotoxicity of each herbal medicine was assessed by measuring the survival and proliferation rate of NCI-H292 cells. Confluent NCI-H292 cells were pretreated for 30 min in the presence of PC, PH, PJ and PS, respectively, and treated with PMA(10 $ng/m{\ell}$), to assess the effect of each herbal medicine on PMA-induced mucin production by enzyme-linked immunosorbent assay(ELISA). Effects of each herbal medicine on PMA-induced MUC5AC gene expression from the same cells were investigated. Also, hypersecretion of airway mucus and goblet cell hyperplasia were induced by exposure of rats to $SO_2$ during 3 weeks. Effects of orally-administered PC, PH, PJ and PS during 1 week on intraepithelial mucosubstances and hyperplasia of goblet cells were examined using histological analysis after staining the epithelial tissue with PAS-alcian blue. (1) PC, PJ, PS and PH did not show significant effects on the survival and proliferation of NCI-H292 cells ; (2) PC, PJ and PS significantly decreased PMA-induced mucin production from NCI-H292 cells ; (3) PC, PJ and PS significantly inhibit the expression levels of PMA-induced MUC5AC gene in NCI-H292 cells ; (4) Among PC, PJ, PS and PH, only PS decreased $SO_2$-induced hyperplasia of airway goblet cells and intraepithelial mucosubstances. This result suggests that PC, PJ and PS can not only affect the production of mucin but also affect the expression of mucin gene and this can explain, at least in part, the traditional use of PC, PJ and PS for controlling airway diseases showing hypersecretion of mucus in oriental medicine.
