Skin wrinkle formations are associated with collagen synthesis and matrix metalloproteinase-I(MMP-1) activity. This study was carried out to find out skin wrinkle reducing components in Torilis Fructus. Torilis Fructus were extracted with 70% ethanol and the ethanol extracts were systematically fractionated with n-hexane, ethylacetate, n-butanol and distilled water. Among them, antiwrinkle component from n-hexane fraction was purified by several column chromatographies and HPLC, which identified as torilin by $^1H-NMR,\;^{13}C-NMR$ and ESI-MS. To determine cell viability, collagen biosynthesis and MMP-1 activity, human dermal fibroblast was treated with 1-5 ppm concentrations of Torilis Fructus extract fraction and torilin. Cell viability was showed 84-102% at all group treated with 1-5 ppm. Collagen synthesis was increased in all group, especially torilin-treated group was highest amount. Active forms of MMP-1 were decreased in all group. From these results, we consider that Torilis Fructus have several antiwrinkle components and torilin may be one of the effective components.

We evaluated the antioxidant activity and anti-wrinkle effects of Aceriphyllum rossii leaf ethanol extract (ARLEE) in vitro using human dermal fibroblasts. The total polyphenol and flavonoid contents of ARLEE were 578.6 and 206.3 mg/g, respectively. At a concentration of $250{\mu}g/mL$, the electron-donating ability of ARLEE was 87.1%. In comparison with the vehicle, ARLEE treatment at $100{\mu}g/mL$ significantly increased type I procollagen synthesis (p < 0.01) by 50.7%. In vitro ARLEE treatment (10 mg/mL) inhibited collagenase and elastase activity by 97.1% and 99.2%, respectively. Compared with the control, ascorbic acid treatment at $100{\mu}g/mL$ significantly decreased matrix metalloproteinase (MMP)-1 protein expression (p < 0.01) by 37.0%. ARLEE treatment at $50{\mu}g/mL$ significantly decreased MMP-1 protein expression (p < 0.01) by 46.1%. Ascorbic acid and ARLEE treatments at $100{\mu}g/mL$ significantly decreased MMP-1 mRNA expression (p < 0.01) by 26.1% and 36.1%, respectively. From these results, we conclude that ARLEE has excellent antioxidant activity and even better anti-wrinkle effects than ascorbic acid in human dermal fibroblasts. These results suggest that ARLEE could be used in functional cosmetics for the prevention or alleviation of skin wrinkles induced by ultraviolet rays.

In this work, the anti-aging skin effects of bacteriochlorophyll a isolated from Rhodobacter sphaeroides are first reported, with notably low cytotoxicity in the range of 1% to 14% in adding 0.00078 (% (w/w)) of the extracts, compared with the normal growth of both human dermal fibroblast and keratinocyte cells without any treatment as a control. The highest production of procollagen from human fibroblast cells (CCD-986sk) was observed as 221.7 ng/ml with 0.001 (% (w/w)) of bacteriochlorophyll a, whereas 150 and 200 ng/ml of procollagen production resulted from addition of 0.001 (% (w/w)) of the photosynthetic bacteria. The bacteriochlorophyll-a-induced TNF-α production increased to 63.8%, which was lower secretion from HaCaT cells than that from addition of 0.00005 (% (w/w)) of bacteriochlorophyll a. Additionally, bacteriochlorophyll a upregulated the expression of genes related to skin anti-aging (i.e., keratin 10, involucrin, transglutaminase-1, and MMPs), by up to 4-15 times those of the control. However, crude extracts from R. sphaeroides did not enhance the expression level of these genes. Bacteriochlorophyll a showed higher antioxidant activity of 63.8% in DPPH free radical scavenging than those of water, ethanol, and 70% ethanol extracts (14.0%, 57.2%, and 12.6%, respectively). It was also shown that the high antioxidant activity could be attributed to the skin anti-aging effect of bacteriochlorophyll a, although R. sphaeroides itself would not exhibit significant anti-aging activities.

Astradalus membranaceus root extract (ARE) contains saponins, flavonoids, and their glycosides. Two flavonoids, calycosin and formononetin, were predominant constituents with the different amount by diverse extraction conditions. ARE showed the anti-oxidative activities, inhibited tyrosinase activity, and increased type I procollagen expression in proportion to calycosin and formononetin contents. The clinical study also showed that skin wrinkles were significantly reduced in the test group treated with a cream formulation containging 0.1% ARE compared with a group treated with a cream formulation without 0.1% ARE (p < 0.05). These results suggest that ARE may have potential as an anti-aging ingredient in cosmetics.

Selenium-containing peptide (Selenium peptide) was produced by autolysis of Saccharomyces cerevisiae which was cultured in inorganic selenium-supplemented medium. Selenium peptide showed antioxidant activity and protective effects on UVB irradiated human fibroblast. Minimal toxicity of selenium peptide was observed whereas selenium nitrate exhibited cell toxicity as low as $10^{-9}\;M$. Selenium peptide also increased human fibroblast growth, procollagen type I and also decreased MMP-1 (matrix metalloprotease-1). This result showed the potential of selenium peptide as a nontoxic antioxidant.

Background Negative-pressure wound therapy (NPWT) induces angiogenesis and collagen synthesis to promote tissue healing. Although acetic acid soaks normalize alkali wound conditions to raise tissue oxygen saturation and deconstruct the biofilms of chronic wounds, frequent dressing changes are required. Methods Combined use of NPWT and acetic acid irrigation was assessed in the treatment of chronic wounds, instilling acetic acid solution (1%) beneath polyurethane membranes twice daily for three weeks under continuous pressure (125 mm Hg). Clinical photographs, pH levels, cultures, and debrided fragments of wounds were obtained pre- and posttreatment. Tissue immunostaining (CD31, Ki-67, and CD45) and reverse transcription-polymerase chain reaction (vascular endothelial growth factor [VEGF], vascular endothelial growth factor receptor [VEGFR]; procollagen; hypoxia-inducible factor 1 alpha [HIF-1-alpha]; matrix metalloproteinase [MMP]-1,-3,-9; and tissue inhibitor of metalloproteinase [TIMP]) were also performed. Results Wound sizes tended to diminish with the combined therapy, accompanied by drops in wound pH (weakly acidic or neutral) and less evidence of infection. CD31 and Ki-67 immunostaining increased (P<0.05) post-treatment, as did the levels of VEGFR, procollagen, and MMP-1 (P<0.05), whereas the VEGF, HIF-1-alpha, and MMP-9/TIMP levels declined (P<0.05). Conclusions By combining acetic acid irrigation with negative-pressure dressings, both the pH and the size of chronic wounds can be reduced and infections be controlled. This approach may enhance angiogenesis and collagen synthesis in wounds, restoring the extracellular matrix.

Bone undergoes continuous remodeling throughout the life and bone health is governed by the balance of bone resorbing osteoclast and bone forming osteoblast. Bone resorption is reflected in tartrate resistant acid phosphatase, pyridinium cross link and collagen telopeptide, whereas bone formation activity can be expressed as bone specific alkaline phosphatase, osteocalcin and procollagen I extension peptide. Milk basic protein and lactoferrin have been reported as active proteins to modulating bone metabolism. In addition to these proteins, some bioactive milk peptides released during lactic fermentation may provide beneficial effect on bone metabolism. The effects of fermented products of Lactobacillus casei ATCC 393 on bone metabolism were investigated using a variety of biochemical markers in osteoblastic MC3T3-E1 cells and ovariectomized rats. Based on the results, the fermented products of Lactobacillus casei ATCC 393 played an functional role in bone metabolism by suppressing bone resorption and by increasing bone formation.

In this study, we investigated the boosting effects on collagen biosynthesis of $Anthriscus$ $sylvestris$ ethanol extract (ASE) in human dermal fibroblasts. To obtain more effective fraction and subfraction for collagen biosynthesis, standard solvent partition and open column chromatography were performed. The EtOH extract, solvent fractions, and 8 EtOAc subfractions were tested for their collagen synthesis capacity by [$^3H$]Proline-incorporation and ELISA assay. ASE increased 25% of total collagen synthesis and 27% of procollagen biosynthesis. The total collagen biosynthesis was increased by EtOAc fraction and E6 subfraction to 28% and 50% respectively. Type I procollagens were also upregulated by EtOAc fraction and E6 subfraction to 30% and 47%, each. Taken together, our data suggest that potential anti-aging effect of ASE on skin is via increasing collagen biosynthesis and effective subtraction is E6 subfraction of EtOAc fraction.

Background: In this study, examined the effects of an extract of a mixture of Angelica gigas, Cnidium officinale, Paeonia lactiflora, and Rehmannia glutinosa fermented by Leuconostoc mesenteroides, with enhanced value and functionality. In oriental medicine, a mixture of these herbs is called Samultang. Methods and Results: In this study, we evaluated the effects of a fermented extract of Samultang on oxidative stress, procollagen type I expression, and melanin production. Samultang was extracted with 70% ethanol, followed by inoculation with Leuconostoc mesenteroides to obtain the fermented extract. The evaluation of viability of B16F10 cells and human foreskin fibroblast (HHF) revealed that both ethanol and fermented extracts of Samultang were non-toxic. The results of 1,1-diphenyl-2-picrylhydrazyl (DPPH) test showed that the fermented extract of Samultang ($SC_{50}value=100{\mu}g/m{\ell}$) was a more effective DPPH free radical scavenger than its ethanol extract. In addition, procollagen type I expression was higher in cells treated with the fermented extract of Samultang than in cells treated with ethanol. In the non-toxic concentration range, the fermented extract of Samultang showed strong inhibitory effect on melanin production in ${\alpha}-melanocyte$ stimulatin hormone-stimulated B16F10 cells ($IC_{50}=37.9{\mu}g/m{\ell}$). Conclusions: These results suggest that the fermented extract of Samultang has considerable protential as a cosmetic ingredient owing to its antioxidant, anti-wrinkle, and whitening effects.

We studied the anti-oxidant and anti-aging activities of Sericinjam Gland Hydrolysate (SJGH) in the human dermal fibroblasts. SJGH effectively defended cell death and ROS generation under high H2O2 in human dermal fibroblasts. Moreover SJGH reduced the expression of SA-${\beta}$-Gal and MMP-1 under low concentration of $H_2O_2$ whereas biosynthesis of procollagen-I was increased. This results demonstrate the anti-oxidant and anti-aging activities of SJGH. SJGH could be a good candidate for anti-aging cosmetics ingredient.
