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 The object of this study was to observe the favorable anti-arthritic effects of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) on Freund's complete adjuvant (FCA)-induced arthritic Wistar rats. Methods Rheumatoid arthritis was induced by intradermal injection of FCA, and 300, 150 or 750 mg/kg of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) were orally administered once a day for 14 days from 14 days after FCA treatments, and 15 mg/kg of dexamethasone was intraperitoneally administered as reference drug in this experiment. All rats were sacrificed at 14 days after continuous oral treatment of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) or intraperitoneal administration of dexamethasone, and changes on the body weight, knee circumferences, gross arthritis score, inflammatory tissue prostaglandin (PG) $E_2$ levels were monitored with cartilage collagen components and glucosaminoglycans compositions - chondroitin sulphate, heparan sulphate and hyaluronic acid in the present study. Results As results of FCA treatment, classic rheumatoid arthritis featuring dramatical decreases on the body weights, cartilage collagen contents and bone glucosaminoglycans-chondroitin sulphate, heparan sulphate and hyaluronic acid contents, with increases on the knee circumferences, gross arthritis scores and inflammatory tissue $PGE_2$ levels. However, these changes from FCA-induced rheumatoid arthritis were clearly reduced by treatment of dexamethasone and both two different dosages of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 and 150 mg/kg in the present study. Although FCA-induced arthritis were more favorably inhibited by treatment of dexamethasone 15 mg/kg as compared with Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg, marked decreases of body weights were detected in dexamethasone 15 mg/kg treated rats, and Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg showed similar preserve effects on the cartilage glucosaminoglycan compositions in this study. Conclusions The results obtained in this study suggest that over 300 and 150 mg/kg of Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) showed favorable anti-arthritic effects on the FCA-induced arthritis mediated by suppression of $PGE_2$, a inflammatory mediator. However, detail mechanism studies should be conduced in future with the screening of the biological active compounds in this herb. Although overall anti-inflammatory effects Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg were lowered than those of dexamethasone 15 mg/kg treated rats, Samki-eum ($s\bar{a}nq\grave{i}-y\check{i}n$) 300 mg/kg treated rats showed similar preserve effects on the cartilage glucosaminoglycan compositions in this experiment.

We have previously screened 150 medicinal plants on the inhibition of elastase and found a significant inhibitory effects of the extracts of Areca catechu L. on the aging and inflammation against the skin tissues. To isolate and identify the compounds having biological activity, we was further purified by each of the solvent fractions, silica gel column chromatography, preparative TLC and reversed-Phase HPLC. Peak in HPLC, which coincided with the inhibitory activity against elastase, was identified as Phenolic substance using various colorimetric methods, UV, and IR. $IC_{50}$/ values of phenolic substance purified from Areca catechu were 26.9 $\mu\textrm{g}$/$m\ell$ for porcine pancreatic elastase (PPE) and 60.8 $\mu\textrm{g}$/$m\ell$ for human neutrophil elastase (HNE). This Phenolic substance showed more potent activity than those of reference compounds, oleanolic acid (76.5 $\mu\textrm{g}$/$m\ell$ for PPE, 219.2 $\mu\textrm{g}$/$m\ell$ for HNE) and ursolic acid (31.0 $\mu\textrm{g}$/$m\ell$ for PPE, 118.6 $\mu\textrm{g}$/$m\ell$ for HNE). According to the Lineweaver-Burk Plots, the inhibition against both PPE and HNE by this phenolic substance was competitive with substrate. Phenolic substance from Areca catechu exhibited high free radical scavenging effect ($SC_{50}$/ : 6 $\mu\textrm{g}$/$m\ell$) and inhibited effectively hyaluronidase activity ($IC_{50}$/: 210 $\mu\textrm{g}$/$m\ell$). These results suggest that the Phenolic substance Purified from Areca catechu showed anti-aging effect by protecting connective tissue proteins.

Objectives: The objective of this study was to evaluate the effects of cytotoxicity, skin regeneration, anti-wrinkle, whitening and skin moisturizing of Oncheongeum (OCE).Methods: The cytotoxicity of OCE lyophilized aqueous extracts (yield=13.82%) was observed against human normal fibroblast cells and B16/F10 murine melanoma cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium Bromide (MTT) assay, and skin regeneration and anti-wrinkle effects were also evaluated through the assay of collagen type I synthesis compared to the transformation of the growth factor (TGF)-β1, hyaluronidase, collagenase and matrix metalloproteinase (MMP)-1 inhibitory assays compared to oleanolic acid (OA), and elastase inhibitory effects compared to phosphoramidon disodium salt (PP). In addition, OCE’s whitening effects were measured by a tyrosinase inhibitory assay and melanin formation test in B16/F10 murine melanoma cells compared to arbutin, and skin moisturizing effects were observed through a mouse skin water content test, respectively. Results: No OCE treatment-related cytotoxic effects appeared on human normal fibroblasts and B16/F10 murine melanoma cells. OCE concentration-dependently increased the collagen Type I synthesis on human normal fibroblast cells, and also effectively inhibited hyaluronidase, elastase, collagenase and MMP-1 activities. In addition, OCE inhibited melanin production of B16/F10 murine melanoma cells and activity of tyrosinase. And significant and dose-dependent increases of skin water content were detected in OCE-treated mouse skin compared to vehicle control skins. Conclusions: OCE showed favorable and sufficient effects in skin regeneration, anti-wrinkle, whitening and skin moisturizing in this experiment. But more detail mechanisms and studies on the skin protective efficiency of in vivo are needed with the screening of active biological compounds in individual OCE herbs.
