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.

Hair loss affects interpersonal relationships and causes psychological stress. In this study, we investigated the antioxidant activity of Cynanchi Wilfordii Radix (CWR) and its effects on dermal papilla (DP) cells. Antioxidant efficacy was examined by ABTS assay. To confirm the effect on cell activity, MTS assay was performed and cell count was directly measured by hemocytometer. The mRNA expression of genes involved in hair formation and hair loss formation was confirmed by quantitative RT-PCR. CWR has a strong antioxidant activity. Cell viability of DP cells was increased to 118.5% by treatment of 0.5 mg/ml CWR for 24 hours, but the effect on the cell number was insignificant. These results suggest that CWR increases mitochondrial activity without promoting cell proliferation. Treatment of DP cells with 0.5 mg/ml CWR resulted in 48.5% reduction of mRNA expression of type 2 $5{\alpha}$-reductase, a major cause of male hair loss. In addition, mRNA expression of bone morphogenetic pretein (BMP), fibroblast growth factor (FGF)7, and FGF10, which are closely related to hair growth, was also decreased. Reactive oxygen species (ROS) acts as a cause of hair loss. The excellent antioxidant efficacy of CWR is thought to be able to effectively remove ROS. The dihydrotestosterone produced by type 2 $5{\alpha}$-reductase in DP cells is a potent inducer of male pattern hair loss. The inhibitory effect of type 2 $5{\alpha}$-reductase mRNA on DP cells induced by CWR may induce a positive therapeutic effect of male pattern hair loss.
This study was undertaken to investigate the cytotoxicity of orthodontic wires after doing various treatments to the wires. 018x025 inch Stainless steel(A) and Co-Cr(B) wires were used and each of them were divided into 4 groups. A-1 and B-1 groups were as received state, and A-2 and B-2 groups were heat treated. A-3 and B-3 groups were electropolished after heat treatment, and A-4 and B-4 groups were soldered with Ag-solder. Each group had 3 wires and these were sterilized with Ethylene Oxide gas. We used human gingival fibroblast cell culture and agar overlay technique to investigate the cytotoxicity of each group of wires. The cytotoxicity of wire was assessed using reaction index (zone index/lysis index). The findings of this study were as follows. 1. Both of the stainless steel wire and Co-Cr wire showed no cytotoxicity in as received state. 2. Heat treatment or electropolishing of the wires had no effect on the cytotoxicity of the wires 3. Soldered stainless steel wires showed a little wider zone of discoloration than soldered Co-Cr wires, but the zone index and cytotoxicity(reaction index) was not different. 4. Soldered wires showed moderate cytotoxicity in both of the wires.

This study was indicated to enhance the anti-inflammation activities by the fermentation of the fruits of Aronia melanocarpa (Michx.) Elliott. The extracts by 70% ethanol (EE) showed better biological activities than those by hot water (WE) from campared result of the effect of extraction solvents. Then, the extract from 70% ethanol extraction was further fermented by lactic acid, denoted as FEE. For antioxidant activities, the FEE had showed the highest value as 0.832 of reducing powder, in comparison with those of EE and WE. Cytotoxicity of the water extraction (WE) was measured for 12.06% in addition of $1.0mg/m{\ell}$ of FEE. For anti-inflammation activities, NO production from the macrophage, RAW 264.7 was observed as $7.24{\mu}M$ and $8.52{\mu}M$ from FEE and EE, respectively. Prostaglandin $E_2$ ($PGE_2$) production from human fibroblast cell, CCD-986sk, was also estimated for $152pg/m{\ell}$ in addition of $1.0mg/m{\ell}$ of the FEE. The lowest production of both IL-6 and TNF-${\alpha}$ were $3.5pg/m{\ell}$ and $865.5pg/m{\ell}$, respectively in addition of $1.0mg/m{\ell}$ of the FEE, whereas $74.5pg/m{\ell}$ and $982.4pg/m{\ell}$ in treated with same concenrations of the EE. It was also found that the FEE was higher amounts than other extracts through HPLC analysis of the anthocyanins. These results strongly indicate that fermentation process of the lactic acid could enhance anti-inflammation activities of extracts by increasing the amounts of the anthocyanins, especially cyanidin-galactoside. Our results suggest that the application of the fermentation process for other medicinal herbs can be improved their biological activities.
Recent studies determined that a chronic western-style diet increased the endogenous small heterodimer partner (SHP) protein levels in mice. In experiments with cell cultures, chenodeoxy cholic acid (CDCA) treatment increased endogenous SHP protein levels and reduced the degradation rate of exogenously expressed flag-SHP levels in the human hepatoma cell line, HepG2 cells. In addition, bile acid-induced intestinal fibroblast growth factor-19 (FGF-19) increased the half-life of the exogenously expressed SHP when HepG2 cells were transfected with ad-flag-SHP. However, both the expression level and the degradation rate of the endogenous SHP in response to cholic acid and FGF-19 have not been well understood, either in mice or in cultured HepG2 cells. This study examined the effects of cholic acid treatment on the endogenous SHP protein levels in mice and the effects of FGF-19 on the degradation rate of the endogenous SHP protein in HepG2 cells. Mice fed 0.5% cholic acid in normal chow showed an increase in endogenous SHP protein levels during both 12 hr and 24 hr treatment periods as compared to control mice fed only normal chow. In cultured HepG2 cells, treatment with CDCA did not noticeably change the rate of degradation in the endogenous SHP protein from cells not treated with CDCA. Although consistent with the previous studies on the exogenous ad-flag-SHP protein, treatment with FGF-19 significantly decreased the degradation rate of the endogenous SHP protein when HepG2 cells were treated with cyclohexamide. These results suggest that both bile acids and FGF-19 increase the endogenous SHP protein levels in mouse liver and HepG2 cells.

The fibroblasts are the principal cells in the periodontal ligament of peridontium. As the periodontal ligament fibroblasts (PDLF) show similar phenotype with osteoblasts, the PDLF are thought to play an important role in alveolar bone remodeling. Cell-to-cell contacted signaling is crucial for osteoclast formation. Recently it has been reported that PDLJ enhance the bone resorbing activity of osteoclasts differentiated from hematopoietic preosteoclasts. The aims of this study were to $clarify\;^{1)}$ the mechanism of PDLF-induced osteoclastogenesis $and\;^{2)}$ whether we can use preosteoclast cell line instead of primary hematopoietic preosteoclast cells for studying the mechanism of PDLF-induced osteoclastogenesis. Osteoclastic differentiation of mouse macrophage cell line RAW264.7 was compared with that of mouse bone marrow-derived M-CSF dependent cell (MDBM), a well-known hematopoietic preosteoclast model, by examining, 1) osteoclast-specific gene expression such as calcitonin receptor, M-CSF receptor (c-fms), cathepsin K, receptoractivator nuclear factor kappa B (RANK) ,2) generation of TRAP(+) multinucleated cells (MNCs), and 3) generation of resorption pit on the $OAAS^{TM}$ plate. RAW264.7 cultured in the medium containing of soluble osteoclast differentiation Factor (sODF) showed similar phenotype with MDBM-derived osteoclasts, those are mRNA expression pattern of osteoclast-specific genes, TRAP(+) MNCs generation, and bone resorbing abivity. Formation of resorption pits by osteoclastic MNCs differentiated from sODF-treated RAW264.7, was completely blocked by the addition of osteoprotegerin (OPG), a soluble decoy receptor for ODF, to the sODF-containing culture me야um. The effects of PDLF on differentiation of RAW264.7 into the TRAP(+) multinucleated osteoclast-like cells were examined using coculture system. PDLF were fxed with paraformaldehyde, followed by coculture with RAW264.7, which induced formation of TRAP(+) MNCs in the absence of additional treatment of sODF. When compared with untreated and fixed PDLF (fPDLF), IL-1 ${\beta}$-treated, or lipopolysaccha-ride-treated and then fixed PDLF showed two-folld increase in the supporting activity of osteoclastogenesis from RAW264.7 coculture system. There were no TRAP(+) MNCs formation in coculture system of RAW264.7 with PDLF of no fixation. These findigs suggested that we can replace the primary hematopoietic preosteoclasts for RAW264. 7 cell line for studying the mechanism of PDLF-induced osteoclastogenesis, and we hypothesize that PDLF control osteoclastogenesis through ODF expression which might be enhanced by inflammatory signals.

Objective: A disintegrin and metallopeptidase with thrombospondin motifs type 8 (ADAMTS8) is crucial for diverse physiological processes, such as inflammation, tissue morphogenesis, and tumorigenesis. The chicken ADAMTS8 (chADAMTS8) gene was differentially expressed in the kidney following exposure to different calcium concentrations, suggesting a pathological role of this protein in metabolic diseases. We aimed to examine the molecular characteristics of chADAMTS8 and analyze the gene-expression differences in response to toll-like receptor 3 (TLR3) stimulation. Methods: The ADAMTS8 mRNA and amino acid sequences of various species (chicken, duck, cow, mouse, rat, human, chimpanzee, pig, and horse) were retrieved from the Ensembl database and subjected to bioinformatics analyses. Reverse-transcription polymerase chain reaction (RT-PCR) and quantitative PCR (qPCR) experiments were performed with various chicken tissues and the chicken fibroblast DF-1 cell line, which was stimulated with polyinosinic-polycytidylic acid (poly[I:C]; a TLR3 ligand). Results: The chADAMTS8 gene was predicted to contain three thrombospondin type 1 (TSP1) domains, whose amino acid sequences shared homology among the different species, whereas sequences outside the TSP1 domains (especially the amino-terminal region) were very different. Phylogenetic analysis revealed that chADAMTS8 is evolutionarily clustered in the same clade with that of the duck. chADAMTS8 mRNA was broadly expressed in chicken tissues, and the expression was significantly up-regulated in the DF-1 cells in response to poly(I:C) stimulation (p<0.05). These results showed that chADAMTS8 may be a target gene for TLR3 signaling. Conclusion: In this report, the genetic information of chADAMTS8 gene, its expression in chicken tissues, and chicken DF-1 cells under the stimulation of TLR3 were shown. The result suggests that chADAMTS8 expression may be induced by viral infection and correlated with TLR3-mediated signaling pathway. Further study of the function of chADAMTS8 during TLR3-dependent inflammation (which represents RNA viral infection) is needed and it will also be important to examine the molecular mechanisms during different regulation, depending on innate immune receptor activation.

Wrinkle formation is mainly attributed to the environmental factors such as UV rays, air pollution, smoking and stress etc. Especially, UV rays induce premature skin aging which is characterized by deep wrinkle, leathery dryness etc. Recently, researches on the wrinkle formation and its prevention have been the main theme in cosmetics fields. We have studied the various plant extracts having anti-wrinkle effects and finally showed that Noni (Morinda citrifolia) extracts have the efficacy of promoting the type I collagen synthesis in normal human fibroblast, using PICP assay. We purified one active compound from Noni extracts and identified its structure. It was identified as 6,7-Dimethoxy-2H-1-Benzopyran-2-one; scopoletin by $^1H-NMR,\;^{13}C-NMR,$ IR, Mass analysis. Scopoletin increased collagen synthesis in a dose dependent manner (89.5% at $0.2{\mu}g/mL$). In order to verify the anti-aging effectiveness of the cream containing 3% noni extracsts, we performed the in vivo test with some female volunteers for 12 weeks. It reduced the signs of aging, especially face wrinkles. From these results, we conclude that the noni extracts could be used as an useful anti-wrinkle agent.
