Objectives : The aim of this study is to investigate anti-inflammation of Leonurus sibiricus methanol extract against UVB-damage in fibroblast. The skin is continuously exposed to damage from environmental stresses. UV radiation causes a variety of biological effects especially on the skin, including inflammation and photoaging. Methods : In this study, we tried to search for Leonurus sibiricus which exhibit protective activities against UVB-induced cytotoxicity and oxidative cell death, NO and $PGE_2$ production. HS68 cells were exposed to UVB ($120mJ/cm^2$) and treated with various concentrations (0, 0.25, 0.5, 1, 2, 4, $8mg/m{\ell}$) of Leonurus sibiricus methanol extract for additional 24 h. Intracellular reactive oxygen species (ROS) levels generated by UV radiation were detected using a spectrofluorometer after DCF-DA staining. Also, HS68 cells were irradiated with UVB and then treated with Leonurus sibiricus methanol extract for 12 h. The lipid peroxidation was assayed by measuring the levels of 8-isoprostane secreted into the culture medium. Results : UVB-induced cytotoxicity and cell death were effectively suppressed by treatment of Leonurus sibiricus aqueous methanol extracts. Oxidative cell damage was mediated $PGE_2$ in UVB-induced HS68 fibroblast cell, which was significantly inhibited by treatment with Leonurus sibiricus extracts. Also, the protective effect of these extract seemed to be mediated by inhibited intracellular ROS generation and lipid peroxidation in dose-dependent manner. Conclusion : These results suggest that Leonurus sibiricus aqueous methanol extracts may have anti-aging effects new functional materials against oxidative UVB stress-mediated skin damages.
