Abstract

|
Objectives : The purpose of this study is to investigate the effect of Shinsuwisaengtang (SSWST) extracts on antioxidant activity and inhibition of phototoxicity as a medicine for skin damage due to ultra violet stimulation.
Methods : To determine the cytotoxicity of Hs68 cells from SSWST extracts, we investigated cell viability by MTT assay. To determine the protective effect of phototoxicity, we investigated cell viability after UVB radiation. The DPPH radical scavenging activity was examined to determine the antioxidant effect of SSWST extracts. Hoechst 33258 staining was performed to observe the protective effect of SSWST on UVB.
Results : The cytotoxicity of SSWST extracts in Hs68 cells was not appeared significantly in all concentration. SSWST extracts significantly increased the viability of UVB-stimulated Hs68 cells at a concentration of 25, 50 and 100㎍/㎖. SSWST extract showed higher DPPH radical scavenging than the control group. It was observed that SSWST extracts inhibited the apoptosis of the UVB-stimulated Hs68 cells through a fluorescence microscope.
Conclusions : It was observed that SSWST did not induce cytotoxicity at a constant concentration and had a protective effect on phototoxicity and an antioxidant effect. Thus, it is considered that it maybe used as a medicine to cure skin damage caused by UVB and photoaging changes in the future.
