Backgrounds : Gamichungsangboha-tang extract has been known to improve pulmonary functions and quality of life within four weeks of treatment. Cessation of treatment causes recurrence of symptoms and regression of pulmonary function and poorer quality of life. Long-term herbal therapy is difficult to maintain due to economic burden and other reasons. AF-365 is made with reduced dosage of Gamichungsangboha-tang extract. This study was designed to evaluate the effectiveness of AF-365 for maintenance therapy. Materials and Methods : The subjects consisted of 27 patients with asthma who had beed treated with AF-365 for four weeks. First, patients were treated with Gamichungsangboha-tang extract for four weeks. Second patients stopped herbal medicine for four weeks and after that they took AF-365. Pulmonary function test(PFT) was checked before and after four weeks of treatment. Quality of Life Questionnaire for Adult Korean Asthmatics(QLQAKA) was checked every two weeks from the beginning. The effects of AF-365 were analysed throughout the last four weeks. Results : Treatment of AF-365 for four weeks resulted in significant increase in PEFR%, QLQAKA. The QLQAKA of the step3, step4 group classified by Global initiative for asthma(GINA) showed significant improvement, and the QLQAKA of the step2 group showed no significant difference. In step3 group, PEFR% increased significantly. Conclusions : This study supports a role for AF-365 in maintenance of pulmonary function and quality of life, especially in persistent symptomatic asthmatics.

Objective: This study aimed to identify the different effects of GMCSBHT water-extract and ethanol-extract on Th1/Th2 differentiation by monitoring Th1/Th2 specific cytokine secretion patterns and the transcriptional activities of T-bet, GATA-3, c-maf, $INF{\gamma}$ and IL-4. Materials and Methods: Spleen cells from eight week-old BALB/c mice were cultured in GMCSBHT extracts containing medium without activation for 24 hours and with activation for 48 hours. CD4+ T cells were isolated and mRNA expression levels of $INF{\gamma}$, IL-4, T-bet, GATA-3, c-maf by RT-PCR and secretion cytokines levels of $IFN{\gamma}$, IL-4 by ELISA were analyzed. Results: GMCSBHT extracts didn't have mitogenic effects on the unstimulated CD4+ T cells. In Th1 skewed condition, GMCSBAHT water extract had no significant effects on mRNA expression levels of $IFN{\gamma}$, T-bet and c-maf, but inhibited mRNA expression levels of IL-4, GATA-3. It showed significantly increased secretion cytokine levels of $IFN{\gamma}$, but had no significant effect on secretion cytokine levels of IL-4. In Th2 skewed condition, GMCSBHT ethanol extract inhibited mRNA expression levels of $INF{\gamma}$, IL-4, GATA-3 and c-maf significantly, but had no significant effects on mRNA expression levels of T-bet. It had no significant effects on secretion cytokine levels of $INF{\gamma}$, but showed remarkable inhibitory effects on secretion cytokine levels of IL-4. Conclusion: Results suggest that on Th1/Th2 deviation, GMCSBHT water extract has both amplifying effects on Th1 differentiation and inhibitory effects on Th2, but GMCSBHT ethanol extract has stronger inhibitory effects on Th2 differentiation than on Th1.
