Objectives: The present study is to observe the skin-regeneration, anti-wrinkle, whitening and skin moisturizing effects of Cheongsangbangpung-tang (CSBPT) with cytotoxicity. Methods: In the present study, cytotoxicity of CSBPT lyophilized aqueous extracts (yield=18.71%) was experimented against human normal fibroblast cells and B16F10 murine melanoma cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium Bromide (MTT) assay, and skin regeneration and anti-wrinkle effects were also showed through the assay of collagen type I synthesis by an enzyme immunoassay (EIA) kit as comparing with transforming growth factor (TGF)-${\beta}1$, hyaluronidase, collagenase and matrix metalloproteinase (MMP)-1 inhibitory assays as comparing with oleanolic acid (OA), and elastase inhibitory effects as comparing with phosphoramidon disodium salt (PP). In addition, whitening effects of CSBPT were observed by tyrosinase inhibitory assay and melanin formation test in B16/F10 melanoma cells as comparing with arbutin, and skin moisturizing effects were measured through mouse skin water contents test, respectively. Results: No CSBPT treatment related cytotoxic effects were demonstrated against human normal fibroblast cells and B16/F10 murine melanoma cells. CSBPT concentration-dependent increased collagen type I synthesis at human normal fibroblast cells. It also effectively suspreessed hyaluronidase, collagenase, elastase and MMP-1 activities, which were enzymes that related to declining of ECM and formation of wrinkle. CSBPT supressed B16/F10 melanoma cells's melanin productions with tyrosinase activity, which was an enzyme connected with melanin formation, and dose-dependent and significant increases of skin water contents were detected in CSBPT treated mouse skin as compared with vehicle control skins. Conclusions: CSBPT showed favorable and enough skin regeneration, anti-wrinkle, whitening and skin moisturizing effects at least in a condition of this experiment. However, more detail mechanism and in vivo skin protective efficacy studies should be conducted in future with the screening of the biological active compounds in individual herbs of Cheongsangbangpung-tang.

Objectives : Oxidative stress seems to play a major role in mechanisms by which ethanol causes liver injury. Previous studies have shown that treatment with Chungganhaeju-tang (Qingganjiejiu-tang, CGHJT) has protective effects on alcoholic liver disease. The aim of this study was to investigate the effects of Chungganhaeju-tang on oxidative stress. Materials and Methods : In vitro, we evaluated the inhibitory activities of CGHJT on DPPH (1,1-diphenyl-2-picryl-hydrazyl), xanthine oxidase, trypsin, and hyaluronidase, and measured cell viability, and proliferation. In the cell culture model, we measured the activities of superoxide dismutase (SOD), and catalase (CAT) after CGHJT treatment in C34 and E47 cell lines, HepG2 cells transfected with/without the cytochrome P450 2E1 (CYP2E1) gene. In vivo, we measured malondialdehyde levels in the liver tissue and alcohol concentration in the blood. Results : CGHJT showed significant free radical scavenging activity against DPPH and xanthine oxidase in the in vitro study, and increased cell viability, proliferation, and activities of superoxide dismutase, catalase in C34 and in E47 cell lines. CGHJT reduced malondialdehyde levels and blood alcohol concentration in vivo, as well. Conclusions : This study suggests that CGHJT has antioxidant effects on oxidative stress by reducing lipid peroxidation and inhibiting the ethanol induced suppression of antioxidant enzyme activities.

To develop new therapy for prevention and treatment of hair loss is very important according to increase of the number of hair loss people. The aim of this study was to investigate the hair growth promoting effects of pectin lyase-modified red ginseng extract (GS-E3D). We examined antioxidant and anti-inflammatory effects, human hair dermal papilla cells (HHDPC) proliferation, and testoterone-induced $5{\alpha}$-reductase inhibitory effects. GS-E3D show not only 1,1-diphenyl-2-picryhydrazyl (DPPH) radical scavenging activity and xanthine oxidase inhibitory effects as an anti-oxidant property, but also lip-oxygenase and hyaluronidase inhibitory effects as an anti-inflammatory property. Human hair dermal papilla cells proliferation by GS-E3D was higher than those of minoxidil or finasteride, using the positive controls. Moreover, GS-E3D exhibited $5{\alpha}$-reductase inhibitory activities after stimulating by testoterone. The present results indicate that GS-E3D has a potential to be as an hair growth promoting agent for cosmetic materials.
