Objective: This study aimed to evaluate the protective effects of Socheongryong-tang (SCRT) on elastase-induced lung injury. Materials and Methods: The extract of SCRT was treated to A549 cells and elastase-induced COPD mice model. Then, various parameters such as cell-based cytoprotective activity and histopathological findings were analyzed. Results: SCRT 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, and gene expression of TNF-α and IL-1β in A549cells. SCRT treatment also revealed the protective effect on elastase-induced COPD mice model. This effect was evidenced via histopathological findings including immunofluoresence stains against elastin, collagen, and caspase 3,and protein level of Cdc2, cyclin B1, and phospho-Erk1/2 in lung tissue. Conclusion: These data suggest that SCRT has pharmaceutical properties on COPD. This study provides scientific evidence for the efficacy of SCRT for clinical application to patients with COPD.
