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.

예로부터 황기는 민간에서 강장제로서 인삼 다음의 보약으로 쓰이고 있다. 본 연구에서는 황기의 성분 중 플라보노이드 화합물로 알려진 calycosin과 formononetin을 유효성분으로 함유하는 황기추출물의 항노화 효과에 대해 알아보았다. Calycosin과 formononetin의 함량은 효소처리 추출방법에 따라 차이가 있었으며, 두 가지 성분들의 함량에 따라 항산화효과 및 tyrosinase 활성 저해효과가 다르게 나타났다. 이러한 연구 배경으로 calycosin과 formononetin을 유효성분으로 함유하는 황기추출물의 피부주름개선 효과를 알아보기 위해 콜라겐 발현효과 및 MMP-1 발현 억제효과를 각각 측정하였다. 그 결과 황기추출물의 콜라겐합성은 증가하였으나, MMP-1 발현 저해효과는 크지 않았다. 또한 0.1% 황기추출물 함유 크림은 대조군에 비하여 피부주름 개선효과를 나타냈다. 이러한 결과를 볼 때 황기추출물은 주름개선용 기능성화장품 신소재로의 응용이 기대된다.

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.

골은 지속적으로 재형성이 일어나며, 오래된 골을 흡수하는 파골세포와 새로운 골을 생성하는 조골세포의 균형에 의하여 항상성이 유지된다. 골대사의 건전성을 측정하기 위한 골흡수 표시자에는 tartrate resistant acid phosphatase, pyridinium 연결부위, 콜라겐 telopeptide 등이 있으며, 골 형성 표시자로는 골 유래 alkaline phosphatase, osteocalcin, procollagen I extension peptide를 사용할 수 있다. 골밀도를 증진하기 위한 기능성 소재로는 milk basic protein, lactoferrin 등이 있으며, 우유의 유산균 발효과정에 의하여 생산되는 생리활성 펩타이드도 골밀도의 증진에 기여할 수 있다. Lactobacillus casei ATCC 393을 이용하여 생산한 발효분해물은 다양한 조골세포의 생화학적 지표 평가와 동물실험 결과를 근거로 할 때 조골세포의 증식과 분화를 촉진하고 파골세포의 활성을 억제시킴으로써 골대사를 개선할 수 있는 것으로 나타났다.

본 연구에서는 전호추출물의 주름개선에 대한 효능을 측정하기 위하여 인간의 섬유아세포에 전호추출물을 처리하여 총콜라겐과 type I procollagen, MMP-1의 생합성에 미치는 영향을 조사하였다. 전호추출물을 인간 섬유아세포에 처리 시 콜라겐의 생합성은 증가시켰지만, MMP-1의 발현에 대해서는 영향을 미치지 못하였다. 이는 전호추출물이 자외선에 의해 영향을 받는 광노화보다는, 노화에 의해 콜라겐 생합성율이 감소되는 내인성노화에 훨씬 유효함을 시사한다. 전호추출물을 처리시 95% EtOH 추출물의 경우 25%까지 총콜라겐의 생합성을 증가시켰고, EtOAc층은 28%, EtOAc의 E6 소분획의 경우 50% 증가시켰으므로, 콜라겐 생합성에 영향을 미치는 유효성분은 EtOAc층에 대부분 함유되어 있을 것으로 사료되고, 이는 확인되지 않은 미지의 효능 성분이 존재하거나, 다양한 활성 성분들의 상호 작용에 의한 것으로 판단된다. 결론적으로 전호추출물은 콜라겐 생합성을 촉진함으로 내인성노화에 의한 주름생성 및 탄력저하를 개선할 수 있는 천연 유용자원으로 이용할 수 있을 것으로 사료된다.

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.

본 논문에서는 세리신잠 실샘 가수분해물(Sericinjam Gland Hydrolysate: SJGH)을 이용하여 진피 섬유아세포에서 항산화 및 항노화 연구를 진행하였다. SJGH는 사람 섬유아세포에서 고농도의 과산화수소에 의한 세포사멸과 세포 내 산화 증가를 효과적으로 방어하였다. 또한 SJGH는 저농도의 과산화수소에 의한 섬유아세포의 SA-${\beta}$-Gal 발현과 MMP-1의 발현 증가를 억제하였고, 반대로 프로콜라겐 I의 생합성은 증가시켰다. 이러한 결과를 통해 SJGH의 항산화 및 항노화 효과가 우수함을 확인하였으며, SJGH가 항노화 화장품의 우수한 소재가 될 수 있음을 보여준다.
