Objective: This study aimed to evaluate the protective effects of Maekmundong-tang (MMDT) on elastase-induced COPD model.
Materials and Methods: The extract of MMDT was treated to A549 cells and elastase-induced COPD mice model. Then, various parameters such as cell-based cyto-protective activity and histopathological finding were analyzed.
Results: MMDT showed a protective effect on elastase-induced cytotoxicity in A549 cells. This effect was correlated with analysis for caspase 3 levels, collagen and elastin contents, protein level of Cdk1, and gene expression of TNF-α and IL-1β in A549 cells. MMDT treatment also revealed the protective effect on elastase-induced COPD mice model. This effect was evidenced via histopathological finding including immunofluence stains against elastin, collagen, and caspase 3, and protein level of Cdc2 in lung tissue.
Conclusion: These data suggest that MMDT has a pharmaceutical properties on COPD. This study would provide an scientific evidence for the efficacy of MMDT for clinical application to patients with COPD.
