One of therapeutics in liver disease (morbus wilson) is D-penicillamin (D-pen: D-3-mercapto-valin). Especially the cross-linking of collagen molecules could be inhibited by D-pe n in extracellular space. In this study we investigated the antifibrotic effects of D-pen in rats that were induced the liver fibrosis by bile duct ligation and scission (BDL/S). Rats were treated for 4 weeks with D-pen after BDL/S operation or sham operation. The balance between fibrogenesis-marker (PNIIIP) and the fibrolysis-maker (PNIVP) were observed in sera by RIA (radioimmunoassay), and the parameter of collagen deposition in liver tissue (hydroxyproline: HYP) was measured by colorimetry. The weight of liver in BDL/S operated group was increased significantly in compared with sham operation group (15.2g${\pm}$1.1, vs 11.9g${\pm}$3.9: p<0.005, p<0.05). The rats group treated by D-pen showed the lower level of PNIIIP (6.7ng/ml${\pm}$1.5, vs 9.5ng/ml${\pm}$2.8) and the higher value of PIVCP (14.0ng/ml${\pm}$1.9, vs 7.9ng/ml${\pm}$1.5) in sera that compared to untreated rats. The content of HYP was decreased by 141% in BDL/S with D-pen treated group than that of it in BDL/S group. No correlation was revealed between collagen parameters in sera and HYP in liver tissue of BDL/S operated and D-pen treated rats. The group treated with D-pen showed the lower value of clinical biochemistry parameters (GOT: glutamate oxalacetate transaminase, Total-Bilirubin) in compared with only BDL/S operated rats, but the value of GPT (glutamate pyruvate transaminase) and Alkaline phosphatase in two BDL/S groups was nearly same. In the histological finding, we observed mild bile duct proliferation, weak inflammation and fibrosis in BDL/S with D-pen treated group, but BDL/S operated group showed the formation of septum (island of hepatocytes), massive bile duct proliferation. This result represents that the BDL/S operation induces liver fibrosis (cirrhosis) in 4 weeks, and D-pen inhibits the synthesis of collagen weakly and stimulates the degradation of collagen in the extracellular space. We conclude that the monitoring of PNIIIP, PIVCP in sera is useful parameter for screening of antifibrotic effect, and D-pen delay the liver fibrosis.

EP was obtained through 20% ethanol extraction of Pueraria lobata root, and the fermented form of EP, FEP, was prepared from the EP after incubating with Lactobacillus rhamnosus vitaP1. There was no significant toxicity by EP and FEP up to $1000{\mu}g/ml$ in NIH-3T3, HaCaT, and B16F10 cells. In addition to antioxidant potentials of EP and FEP determined by DPPH and ABST assays, we confirmed increase of procollagen type I and elastin synthesis by supplementation of the EP and FEP at the concentration of $50{\mu}g/ml$ using ELISA kits. The protein expression levels of matrix metalloprotease (MMP)-1, -3, and -9, those are involved in the degradation of collagen or other skin matrix proteins, were remarkably suppressed while their inhibitory protein metallopeptidase inhibitor 1 (TIMP-1) was greatly up-regulated by supplementation of the EP and FEP at a concentration of $50{\mu}g/ml$. Taken together, both EP and FEP supplementation could be involved in the suppression of the skin wrinkle formation through inhibiting degradation of collagen and stimulating the synthesis of collagen and elastin. The results showed that the anti-wrinkle potential of the EP and FEP will be a promising candidate for developing cosmeceutical compounds or products.

Angelica tenuissima root has historically been used as a traditional medicine in Korea. Previous studies have identified the anti-melanogenic effects of the extract of A. tenuissima root fermented by Aspergillus oryzae (FAT). This study investigated the protective effects of FAT against ultraviolet light B exposure (UVB; $30mJ/cm^2$) in HaCaT (human keratinocyte) or Hs68 (human foreskin fibroblast) skin cells. FAT treatment was able to stimulate wound healing rate at the basal condition. FAT also favored the maintenance and/or improvement of extracellular matrix impairment caused by UVB irradiation through: 1) upregulation of procollagen Type-1 synthesis and secretion; 2) suppression of MMP-1 and elastase expression. FAT was able to play a role in the attenuation of inflammatory responses caused by UVB irradiation via upregulation of photo-protective hemeoxygease-1 and suppression of proinflammatory cyclooxygenase-2 expression. After further verification of the anti-photoaging potential of FAT, it could be utilized as an effective ingredient in anti-aging and anti-wrinkle cosmetics.
The aim of this study was to evaluate the anti-oxidant and anti-wrinkle effect of the black carrot(BC) extracted by supercritical dioxide(SC-CO2). DPPH/ABTS radical scavenging and total polyphenol contents were measured to investigate the anti-oxidant activity of the BC supercritical extract. Collagen production and MMP-1 expression were assessed in normal human dermal fibroblasts(NHDF) for anti-wrinkle activity, The black carrot extract showed the highest total phenolic content(9.037±1.123 mg GAE/g extract) and the best antioxidant properties as shown by DPPH and ABTS assay. The supercritical fluid extracts of black carrot exhibited low toxicity to NHDF cells. In addition, the supercritical fluid extracts showed MMP-1 inhibition and type I pro-collagen synthesis inducing activities in a dose-dependent manner, respectively. Therefore, these results suggest that the black carrot is a potential source of high anti-oxidative, solvent-free and anti-aging material with promising applications in cosmetic, food, and beauty-food industries.

Lespedeza cuneata G. Don is a traditional herb that has been associated with multiple biological activities. In this study, we investigated the antioxidative/antiaging activities and performed an active component analysis of the non-fermented and fermented (using Lactobacillus pentosus) extracts of Lespedeza cuneata G. Don. The antioxidative activities of the fermented extract were higher than those of non-fermented extracts. The elastase inhibitory activity, inhibitory effects on UV-induced MMP-1 expression, and ability to promote type I procollagen synthesis were investigated in Hs68 human fibroblasts cells. These tests also revealed that the fermented extract had increased antiaging activities compared with the non-fermented extract. A component analysis of the ethyl acetate fractions of non-fermented and fermented extracts was performed using TLC, HPLC, and LC/ESI-MS/MS to observe changes in the components before and after fermentation. Six components that were different before and after fermentation were investigated. It was thought that kaempferol and quercetin were converted from kaempferol glucosides and quercetin glucosides, respectively, via bioconversion with the fermentation strain. These results indicate that the fermented extract of L. cuneata G. Don has potential for use as a natural cosmetic material with antioxidative and antiaging effects.

[ $Interferon-\gamma$ ] has been suggested as a cytokine of connective tissue stabilizer. In addition, it has also been demonstrated that this cytokine inhibited bone remodeling activities of the bone derived cells. In order to illuminate the effects of this cytokine in orthodontic force induced bone remodeling, it was administered to primary cultured periodontal ligament cells which have been known to have some osteoblast like characteristics. $Interferon-\gamma$ slightly decreased $[^3H]thymidine$ incorporation rate without a significant change in the total cellular DNA content up to 1000 U/ml, which meant these doses were not cytotoxic to the cell. Total protein synthesis was not influenced by various concentration of interferon-y whether it was determined by the $[^3H]proline$ incorporation rate or by the Lowry smethod. The effect of $interferon-\gamma$ on the individual protein was, however, differential, ie, it increased $[^3H]proline$ incorporation into the noncollagenous protein marginally, while it decreased $[^3H]proline$ incorporation into the collagen, so that it caused dose-dependent suppression of the relative collagen synthesis. On the contrary, the fibronectin synthesis determined by the ELISA was increased by 1000 U/ml of $interferon-\gamma$. The differential effects of the interferon-y on the collagen and fibronectin synthesis exhibited not only their protein level but also the steady state mRNA level. $Interferon-\gamma$ decreased steady state level of ${\alpha}1(I)$ procollagen mRNA significantly, while showing no significant changes in the fibronectin mRNA level. In addition to this, it was also found that indomethacin did not affect on the $interferon-\gamma$ induced collagen decrease in this cell, which meant prostaglandins were not involed in the process of $interferon-\gamma$ induced collagen decrease. So it can be concluded that the incubation of periodontal ligament cells with 1000 U/ml of $interferon-\gamma$ for 24 hr showed differential effects on the type I collagen and fibronectin gene expression. The decrease in relative collagen synthesis in the protein level was related with decrease in the steady state level of mRNA, while the increase in the fibronectin synthesis in the protein level was not correlated with the mRNA level.

Acerola is an excellent ingredient because of its high natural vitamin C content, but it is difficult to stabilize and has hardly been studied as a cosmetic material. Therefore, this study developed a mixed liposome preparation for stabilizing acerola extract. As a safety test, the skin irritation test was evaluated by BCOP assay and HET-CAM assay. We evaluated the inhibition of tyrosinase activity, the whitening effect of melanin production, and the wrinkle effect of prochloragentype-I C-peptide production, and confirmed the possibility of functional cosmetics. In addition, a cream of liposomes containing acerola extract mixture was developed to evaluate the clinical studies of skin wrinkles and whitening. BCOP assay, HET-CAM assay and human skin primary irritation test results of liposomes containing acerola extract mixture showed no irritation and were safe from skin and eye. The result of tyrosinase activity by 75.8% at 1,000 ㎍/mL. As a result of the melanogenesis inhibition test, liposome with acerola extract showed the melanin content by 46.2% at 1,000 ㎍/mL that does not effect the viability of the B16F10 cell line. The result of collagen production test using ELISA kit, liposomes containing acerola extract mixture showed collagen synthesis ability by 152.1% at 1,000 ㎍/mL that does not affect the viability of the HS68 cell line. But it did not showed any inhibition of collagenase (MMP-1) activity at all concentrations in the MMP-1 activity inhibition test in the HS68 cell line. We performed clinical studies for the whitening and skin-wrinkle activity of cream containing acerola extract mixes liposome, was showed that the melanin contents and wrinkle was statistically significant reduction. These results suggest that liposomes containing acerola extract mixture have safe natural material, and skin wrinkle, whitening effects allowing their application in cosmetics as a natural product.

Background : The white jelly mushroom (Tremella fuciformis), one of the most popular edible fungi, has medicinal properties. However, the effects of T. fuciformis in skin whitening or anti-wrinkle efficacy has not been defined to date. The aim of the present study was to investigate the effects of T. fuciformis extracts on whitening and anti-wrinkle efficacy in skin cells. Methods and Results :We prepared T. fuciformis extracts with water. The extracts ($80^{\circ}C$) contained 12.11 mg/g polyphenol and 8.54 mg/g flavonoid concentration. T. fuciformis extracts markedly decreased melanin contents and tyrosinase activity in ${\alpha}$-MSH-stimulated melanocytes (B16F10 cells). In addition, the mRNA expression of melanin formation factors, such as microphthalmia-associated transcription factor (MITF), tyrosinase-related protein-1 (TRP-1) and tyrosinase-related protein-2 (TRP-2) were significantly down-regulated in ${\alpha}$-MSH-stimulated melanocyte. Furthermore, T. fuciformis extracts increased the synthesis of type I procollagen and reduced mRNA expression of matrix metalloproteinase 1 (MMP-1) in the human dermal fibroblast (HDFn cells). These data indicated that T. fuciformis extracts induce repression of cellular melanogenesis and protect against wrinkles caused by UVB-stimulated damage. Conclusions : Thus T. fuciformis extracts could be a cosmetic candidate for skin whitening and anti-wrinkle effects.

In this research, the anti-inflammatory, antioxidant, antiaging, and skin whitening properties of pulp and seed extracts of passion fruit were studied. The result of the primary skin irritation test using a skin-attached patch determined the skin irritation index to be 0.00 for the passion fruit extract. In addition, RAW 264.7 macrophages produce NO by stimulation of lipopolysaccharides, and the application of extracts to this resulted in significantly lower NOs, confirming the excellent anti-inflammatory properties of passion fruit extracts. The 2,2-diphenyl-1-picrylhydrazyl test further confirmed that the passion fruit extract exhibits a good 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonate radical scavenging ability of 5.11% and strong antioxidant properties. The presence of collagen type I in the skin is a measure of aging and various skin diseases. The results obtained from the analysis of the activity of human procollagen I alpha 1 confirmed that the passion fruit extract reduces the synthesis of procollagen. In addition, the skin whitening property of the passion fruit extract was confirmed by the melanin inhibition test, and a sample was obtained that contained more than 2% of arbutin, a whitening agent approved by the Ministry of Food and Drug Safety, which is generally present in the form of a white powder and is used as a functional ingredient. This confirms that the whitening efficacy of the passion fruit extract obtained from nature contributes to the development of functional raw materials for cosmetics and food.
The essential oil from Abies koreana E.H. Wilson had been developed, however, its efficacy has not yet been studied especially in terms of skin care research. The aim of this study is to investigate the effects of Abies koreana extracts (AKE) on melanogenesis and wrinkle formation in B16F10 melanoma cells (B16F10) and human dermal fibroblast cell line (HDF). The essential oil was extracted by hydrodistillation method and purified by anhydrous sodium sulfate. At a concentration of $10^{-5}$-fold, viability in these cells had been defined by cytotoxicity assays. Anti-melanogenic effects on B16F10 were evaluated using tyrosinase inhibition assay, and real-time PCR for verifying gene expression of tyrosinase, tyrosinase related protein-1 and -2 (TRP-1 and -2). AKEs reduced about 5-fold of tyrosinase inhibitory activity compared to ${\alpha}$-melanocyte-stimulating hormone (${\alpha}$-MSH)-induced group and about 30% reduction compared to Arbutin induced group. The mRNA levels of three melanin-related factors were increased, separately. To investigate the effects of anti-wrinkle, procollagen type I c peptide synthesis assay (PIP) and Western blot were performed. At AKE-treated group, PIP was up-regulated and the expression of collagen type 1 and matrix metalloproteinase (MMP)-1 were improved. Furthermore, AKE presented anti-wrinkle effects by increasing UVB-inhibited collagen type 1 expression, and reducing UVB-induced MMP-1 production at $60mJ/cm^2$ of UVB radiation. Therefore, Abies koreana extracts has potentials as a safe and an effective skin ingredient for whitening and anti-wrinkle.
