The effects of orally administered fermented porcine placenta (FPP) and its major dipeptides, L-Leucyl-Glycine (Leu-Gly) and Glycyl-L-Leucine (Gly-Leu), on UVB-induced wrinkle formation of the skin in hairless mice was studied. Treatment with FPP, Leu-Gly or Gly-Leu increased type I procollagen synthesis and decreased MMP-1 (matrix metalloproteinase-1) in human dermal fibroblast cells (HDF-N). Hairless mice were also exposed UVB irradiation three times a week and fermented porcine placenta extract (FPP), Leu-Gly and Gly-Leu was administered once a day for eight weeks. Daily intake of FPP, Leu-Gly and Gly-Leu for eight weeks decreased wrinkles, erythema and thickness of the skin and increased skin hydration and synthesis of collagen relative to a UVB-control. Moreover, FPP, Leu-Gly or Gly-Leu intake decreased the expression of MMP-3 and MMP-13 mRNA levels and inhibited activation of MMP-2 and MMP-9 induced by UVB irradiation in hairless mice skin. These results suggest that major dipeptides of the placenta, Leu-Gly and Gly-Leu have the potential for use as a functional food ingredient with anti-wrinkling properties.

To identify new active anti-wrinkle ingredients, this study investigated the anti-wrinkle effects of Schizandra chinensis Baillon fermented with Lactobacillus plantarum (SCF) by assessment of cytotoxicity of human dermal fibroblast, collagen biosynthesis, matrix metalloproteinase-I (MMP-1) inhibition and elastase inhibition. S. chinensis was fermented with L. rhamnosus for 1 day at $37^{\circ}C$. The cytotoxicity of SCF was evaluated by a cytopathic effect reduction method. Effects on collagen biosynthesis and matrix metalloproteinase-I (MMP-1) of SCF were evaluated by previous reported method using procollagen type-IC peptide EIA kit and Matrix Metalloproteinase-1 Biotrack activity Assay Kit, respectively. Elastase inhibition assay was conducted by reaction of enzyme and substrate using N-Suc-$(Ala)_3$-nitroanilide as the substrate. As the results, SCF didn't show cytotoxicity against human dermal fibroblast at concentration of $100{\mu}g/mL$. Also, SCF was increased collagen synthesis and showed inhibitory effect of MMP-1 (p < 0.05). In the elastase inhibition assay, the $IC_{50}$ of SCF was $36.4{\mu}g/mL$. Therefore, our results indicated that SCF possesses anti-wrinkle effects and can be used practically for anti-wrinkle care of skin.

Hwangryunhaedoktang (HHT) has been traditionally used as a preventive and therapeutic medicine to treat enervation and diverse chronic diseases. This study was designed to compare the antioxidant, anti-wrinkle and whitening effects of HHT extract and its fermented extract by Leuconostoc mesenteroides (FHHT). FHHT was prepared by inoculation of L. mesenteroides after the extraction procedure with 70% ethanol. HHT and FHHT was investigated via high-performance liquid chromatography (HPLC). Simultaneous qualitative analysis of two bioacitive components, berberine and palmatine. was achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard components. Cell viability test results indicated that both HHT and FHHT were non-toxic. In DPPH radical scavenging ability, $SC_{50}$ values of the FHHT was $68.85{\mu}g/mL$, which is more effective than HHT. Moreover, FHHT showed higher expression in production of procollagen type I than HHT. In nontoxic concentration range, FHHT showed strong melanin production inhibitory effect in ${\alpha}-melanocyte$ stimulating hormone (${\alpha}-MSH$)-stimulated B16F10 cell ($IC_{50}=9.82{\mu}g/mL$). These results suggested that fermented extracts of hwangryunhaedoktang had considerable potential as a cosmetics ingredient with an antioxidant and anti-wrinkle and whitening effects.

The effect of lactic acid bacteria.fermented ginseng berry extract (FGBE) on physiological activities was evaluated. The contents of ginsenosides Re, Rc, and Rb1 in ginseng berry extract (GBE) were increased after fermentation by lactic acid bacteria when analyzed by high performance liquid chromatography. Antioxidant activity of GBE and FGBE was also analyzed by DPPH radical scavenging activity assay and SOD.like activity assay. FGBE showed a 86.34 % inhibition of DPPH radical and a 76.82 % inhibition by SOD.like activity at a concentration of 1.00 %. GBE showed a 49.78 % inhibition of DPPH radical and a 40.80 % inhibition by SOD.like activity at the same concentration. Furthermore, procollagen type I (COL1A1) gene expression increased by 823.13 % and matrix metal-loproteinase(MMP)-1 and tumor necrosis factor (TNF)-${\alpha}$ gene expression decreased by 87.88 % and 99.92 %, respectively, in human fibroblast cultured with FGBE at a concentration of 0.50 %. These results suggest that FGBE could be used as an active ingredient for functional cosmetics.

The antioxidant, whitening, and anti-wrinkle activity of Spirodela polyrhiza extracts and fractions were evaluated to determine its efficacy as a functional cosmetic material. 1,1-diphenyl-2-picrylhydrazyl and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activities were 44.2 and 74.3%, respectively, at 100 ㎍/mL of SE-E (the ethyl acetate fraction of 70% ethanol extract). To measure anti-wrinkle effects, procollagen biosynthesis and matrix metalloproteinase-1 (MMP-1) inhibition activity were determined. At 25 ㎍/mL of SE (70% ethanol extract), the biosynthesis activity was 48.5%, and SE-E showed the best activity (57.8%) at the same concentration. MMP-1 inhibition activity of SE and SE-E was 13.4 and 28.5%, respectively, at 25 ig/mL. Finally, the inhibition of cellular melanin synthesis and cellular tyrosinase were measured to determine the whitening effect; at 25 ㎍/mL, the inhibition activities of SE were 9.6 and 13.8%, respectively, and those for SE-E were 15.4 and 22.0%, respectively. Our results confirmed the possibility of SE and SE-E as effective functional materials. Further research investigating the antimicrobial, anti-inflammatory, and anticancer activities of S. polyrhiza is necessary to confirm its potential use in the food, cosmetics, and drug industries.

In this study, extracts from the Green ball apple peel (GBE) and the newly bred green ball apple from Korea showed inhibition effects on photo-aging factor regulation associated with skin aging. To investigate the inhibition effect on photo-aging factor regulation in skin, GBE was treated with UVB to induce photo-aging related factors in CCD986sk fibroblast cells. Photo-aging factor regulation effects showed that GBE inhibited UVB-stimulated matrix metalloproteinase (MMP)-1 and MMP-9 protein synthesis in collagen type I alpha 2 chain (COL1A2), MMP-1, MMP-9, and tissue inhibitors of metalloproteinase (TIMP)-1 protein expression. The expression of COL1A2 and TIMP-1 protein was significantly increased. The mRNA expression levels of COL1A2, MMP-1, MMP-9, hyaluronan synthase (HAS)2, transforming growth factor (TGF)-β, and TIMP-1 were decreased by GBE. The expression of TIMP-1 and TGF-β, which are regulators involved in matrix metalloproteinase and type I procollagen expression, was found to increase with increasing expression of COL1A2. The expression of HAS2, which is involved in the production of hyaluronic acid, one of the structural proteins constituting the skin, was also confirmed. Therefore, GBE showed excellent efficacy against photo-aging factor regulation and could be used as functional material to prevent and treat skin aging.

To examine the effects of a mycosporine-like amino acids (MAAs) mixture from microalgae, Chlamydomonas sp, on the anti-wrinkle activities, the expression levels of genes that are associated with skin aging, including type I procollagen, elastin and involucrin, were analyzed. Asterina 330+palythine (A+P) and shinorine+palythine (S+P) mixtures were purified from Chlamydomonas sp using the following steps: 80% methanolic extraction, column purification, and HPLC analysis. As a result of the MTT assay, A+P and S+P did not induce cellular cytotoxicity with up to 0.1 mg/mL of both MAAs. In addition, the treatment of UV-exposed fibroblasts with A+P (0.05 mg/mL) and S+P (0.01 mg/mL) increased the levels of the PCOLCE mRNAs by 2.7 and 3.6 fold compared to the control group, respectively, The levels of elastin gene expression were elevated 5.59 and 3.1 fold in the A+P and S+P treated (0.01 mg/mL) cells, respectively. In particular, at a concentration of 0.01 mg /mL, the A+P and S+P expression levels of Involucrin mRNAs were increased 3.5 and 2.5 fold in the UV-exposed cells compared to the control, respectively. In conclusion, the MAAs derived from Chlamydomonas sp can be utilized as functional cosmetic materials with anti-wrinkle effects on the skin.

The root of Panax ginseng C. A. Meyer has been used as a traditional anti-aging and anti-wrinkle agent in the Orient. However, it is still unknown which component of ginseng is effective at suppressing wrinkle formation. Recently at least twenty ginsenosides regarded as the main active ingredients of ginseng have been isolated. Among them, we examined the effect of ginsenoside Rg3 on dermal ECM metabolism to elucidate the mechanism of anti-wrinkle by ginseng. In our study, to investigate the anti-wrinkle effect of the ginsenoside Rg3, ECM component and growth factor in dennis were evaluated by ELISA assay. Ginsenoside Rg3 was found to stimulate type I procollagen and fibronectin (FN) biosynthesis in a dose-dependent manner in normal human fibroblast culture (p < 0.05, n =3), and dose-dependently enhance TGF- ${\beta}$1 level (p < 0.05, n =3). In RT-PCR analysis mRNA level of c-Jun, a member of AP-1 transcription factor, was reduced by ginsenoside Rg3 in normal human fibroblast culture. These results indicate that ginsenoside Rg3 stimulates type I collagen and FN synthesis through the changes of TGF - ${\beta}$1 and AP-1 expression in fibroblasts.

In this study, we conducted research to find anti-wrinkle skin care ingredients from natural sources via the measurement of procollagen type 1 levels in the medium of normal human dermal fibroblast (NHDF) and found that a Nelumbo nucifera leave extract (NLE) was as the best effective ingredient. By the high performance liquid chromatography analysis, we confirmed isoquercitrin was one of the main compounds of NLE. Moreover, it also increased the procollagen type 1 production without cytotoxicity of NHDF. NLE and isoquercitrin exerted free radical scavenging activity. Especially, isoquercitrin exhibited strong intracellular antioxidant capacity in human skin-derived cells, HaCaT and NHDF. Finally, we performed clinical test for the inhibitory effect of NLE on skin wrinkle formation. A randomized study was conducted in 22 healthy female volunteers, aged between 30 and 65 yrs, with moderate to moderately severe facial wrinkles. Volunteer applied a 1.7% NLE cream (isoquercitrin 51 ppm) and a control cream at each facial side (left/right) twice daily for 8 weeks. The 1.7% NLE cream improved skin roughness through reducing the wrinkle of the craw's feet significantly without any skin side effect. Our results demonstrate that NLE and isoquercitrin can increase the collagen production and exert antioxidant activity. Therefore, we expect that the new non-toxic herbal extract, isoquercitrin-containing NLE will be interesting natural ingredient of cosmetics with anti-wrinkle efficacy.

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.
