  • Objectives : To investigate the effects of Ohbaesangami (OBSGM) on mucosa and skin diseases, anti-microbial and anti-inflammatory tests were performed using several in vitro test models. Results : In anti-microbial test, OBSGM showed the slight inhibitory effect against Propionibacterium acnes (P. acnes) and Staphylococcus aureus (S. aureus). In anti-oxidant test, OBSGM showed the potent radical scavenging activity. In anti-inflammatory test, OBSGM weakly inhibited the lipopolysaccharide (LPS)-induced nitric oxide(NO) release from the RAW 264.7 macrophage cells. OBSGM also inhibited the LPS-induced $interleukin-1{\beta}(IL-1{\beta})$ and cyclooxygenase-2 (COX-2) expressions. The inhibitory effects of OBSGM on macrophage activation was via the inhibition of $NF-{\kappa}B$, evidenced by transient transfection assay. Furthermore, OBSGM markedly inhibited the activation of Jun-N-terminal kinase (JNK) and p38 MAP kinase in RAW 264.7 cells. In skin wrinkle formation assay, OBSGM strongly inhibited collagnease and elastase, whose activities are tightly related with the wrinkle formation. In addition, OBSGM inhibited the activities of MMP-1, MMP-2 on the mRNA levels in RAW 264.7 cells. However, OBSGM did not show an inhibitory potential on tyrosinase activity and melanin synthesis, indicating that it could not be applicable for skin whitening. Conclusion : These results suggest that the anti-inflammatory effect of OBSGM may be due to its inhibitory potentials on the macrophage activation. And, the anti-wrinkle effects of OBSGM may be due to its inhibitory potential on the collagnease and elastase activities. Therefore, OBSGM could be applicable for the treatment of mucosa and skin diseases.

  • UV irradiation causes skin-aging involving coarse wrinkles, thickening, dyspigmentation, and rough skin surface. This study was carried out to develop health & functional food by using Korean red ginsneg and Fagopyrum esculentum extract mixture (RGFE) for prevention of skin wrinkles. The RGFE-treated group showed the more effective collagenase inhibition rate than the red ginseng (RG)-treated group. To investigate photo protective effects of RGFE on UV-induced damaged skin, SKH hairless male mice were orally administerd RGFE and regional treatment and irradiated with UV for up to 8 weeks. In RGFE-treated group, better skin, and less wrinkle formation were observed compared with UV group. Epidermal thickness of hairless mouse was significantly decreased in RGFE, RG, and Fagopyrum esculentum (FE) groups compared with UV group. These results demonstrate RGFE have photo-protective effects on UV-damaged hairless mouse skin.

  • 무의 껍질과 무청은 식용으로 사용하기도 하지만, 질기고 거친 식감으로 인하여 제거 후 부산물로서 폐기되거나 가축의 사료로 이용되는 실정이다. 본 연구는 초임계 열처리가공 무추출물이 UVB로 유도된 Hos:HRM-2 주름생쥐동물모델에서 항-광노화 주름개선 효능을 검증하고자 하였다. 초임계 열처리된 무 추출물을 7주령의 HRM-2 생쥐에 UVB 램프로 등피부에 조사하여 피부 노화를 유발하여 피부두께, 탄력, 그리고 주름생성 변화에 대하여 알아보고자 하였다. 초임계 열처리된 무추출물의 UVB 조사에 의한 HRM생쥐의 주름 측정 결과는 정상군에 비해 음성대조군의 주름의 깊이가 증가되는 것을 관측할 수 있었다. 반면 무 추출물의 처리군에서는 음성대조군에 비해 주름의 깊이가 감소되었다. 초임계 열처리된 무추출물의 UVB 조사에 의한 의한 주름관련 유전자 및 단백질의 발현에 미치는 영향에서는 음성대조군은 정상군에 비해 MMP-2 및 MMP-9 유전자의 발현이 현저하게 증가하였으나, 무 추출물의 처리에 의해 상기 유전자의 발현이 유의적으로 감소하는 것을 확인할 수 있었다. 또한 유전자의 발현 정도는 무 추출물의 처리량에 의존적으로 감소하였다. 실험결과를 종합적으로 해석해 볼 때, 초임계 열처리된 무 추출물은 피부에 도포 시 뿐만 아니라 경구로 섭취시에도 피부 주름 개선에 효과가 있어, 건강기능식품 조성물로도 유용하게 사용될 수 있다. 특히 무는 오랫동안 복용 시에도 전혀 부작용을 나타내지 않는 안전한 식품으로 장기간 꾸준히 복용하는 것에 의해 피부 주름 및 탄력 개선 효과를 얻을 수 있다는 결론을 얻을수 있었다.

  • The matrix metalloproteinases (MMPs) are a family of enzymes responsible for degrading connective tissue. MMPs catalyze the breakdown of collagen from the extracellular matrix, leading to wrinkle formation and accelerated skin aging. Furthermore, ultraviolet irradiation causes increased expression of certain MMPs. In the extracellular matrix turnover, MMPs are interacting with endogenous regulators named tissue inhibitors of metalloproteinases (TIMPs). Using peptide substrate assays, it has been demonstrated that TIMP-MMP complexes interact highly specifically with $K_{i}$ values of 10$^{-9}$ -10$^{-16}$ M. Therefore applications for TIMP as inhibitor of collagen degradation are suggested for cosmetic anti-aging products to prevent wrinkle formation and loss of elasticity. To date four TIMP proteins (TIMP-1, TIMP-2, TIMP-3 and TIMP-4) have been identified which show a high degree in sequence similarity. The production of human TIMP-2, a 194-residue nonglycosylated protein, was performed by fed-batch culture of Escherichia coli. TIMP-2 accumulated in the bacterial cells in an insoluble form as inclusion bodies. The inclusion bodies were solubilized and the protein refolded to yield the native TIMP-2 in the active form. The integrity of the protein was confirmed by mass analysis, Edman sequencing and gel shift experiments with authentic samples. The inhibitory activity of the refolded and purified TIMP-2 was demonstrated with MMP-1 and MMP-2 assays using synthetic fluorogenic peptide substrates.s.

  • In this study, the performance of ultrasonic cleaners for ultrasonic washing, which is one of the wet cleaning methods, was evaluated. The washing performances of ultrasonic cleaners were compared with commercial washing machines under normal and wool courses based on different parameters such as detergency, wrinkle formation, fabric damage, dimensional stability, and germ removal ability. Cotton, silk and wool were used in this experiment. Results revealed that the ultrasonic washing detergency of cotton fabrics was lower than that of commercial washing machines under the normal course and similar to that of commercial washing machines under the wool course. Detergency of silk fabrics was similar under both normal and wool courses. In terms of wrinkle formation and dimensional stability, ultrasonic cleaners showed lesser wrinkles and lower shrinkage than commercial washing machines. Considering damage evaluation, ultrasonic cleaners more effectively removed soil without damaging fabrics compared with commercial washing machines. The bacteria removal rate of both cotton and silk was more effective than the wool course of a commercial washing machine. Thus, this study compares the performance of ultrasonic cleaners and commercial washing machines and provides meaningful results related to ultrasonic washing performance.

  • The roots of reed (Phragmites australis) were used in traditional medicine to treat respiratory problems, including symptoms such as high fever and cough. In this study, we identified the active ingredient from 70% EtOH reed root extract, and evaluated the whitening, wrinkle improvement and moisturizing effects. The content of p-coumaric acid, the active ingredient of the roots of P. australis, was slightly lower in 70% EtOH extract than in 100% EtOH extract. However, 70% EtOH reed root extract showed similar or higher effect in reducing power, DPPH, hydrogen peroxide scavenging, and nitric oxide scavenging activity compared to 100% EtOH extract. Moreover, 70% EtOH reed root extract markedly inhibited melanogenesis in B16F10 cells treated with α-melanocyte-stimulating hormone. 70% EtOH reed root extract significantly inhibited the mRNA expression of matrix metalloproteinase-1 (MMP-1) and reduced elastase activity in HDF human dermal fibroblasts. In addition, 70% EtOH reed root extract ameliorated hyaluronic acid synthase-2 (HAS-2) expression induced by ultraviolet B (UVB) stimulation in HaCaT keratinocytes. The results of this study suggest that 70% EtOH reed root extract has potential as a functional cosmetic material related to whitening, wrinkle improvement, and moisturizing.

  • 인삼(Panax ginseng C. A Meyer)의 뿌리는 전통적인 항-노화 및 항-주름제로 동양에서 사용되어 왔다. 그러나 인삼의 어떤 성분이 주름 형성을 억제하는데 효과적인지는 아직 밝혀지지 않았다. 최근 인삼의 주요 활성 성분으로 생각되는 ginsenosides가 20가지 이상 분리되었다. 이들 중 본 연구원들은 인삼에 의한 항-주름의 작용기작을 밝히기 위해 세포간질(extracellular matrix, ECM) 물질대사에 있어 ginsenoside Rg3의 진피에서의 효과를 시험하였다. 본 연구에서, ginsenoside Rg3의 항-주름 효과를 연구하기 위해 진피의 세포간질 구성 성분과 성장 인자를 ELISA (enzyme-1in14ed immunosorbent assay) 측정법으로 평가하였다. Ginsenoside Rg3은 human dermal fibroblasts 배양에서 type I procollagen과 fibronectin(FN) 생합성을 농도 증가에 비례하여 촉진시키고(p < 0.05, n=3), 농도에 비례하여 TGF-$\beta$1 수준을 증가 (p < 0.05, n=3) 시키는 것으로 밝혀졌다. RT-PCR 분석에서 AP-1 전사 인자(transcription factor)의 일부인 c-Jun의 mRNA 수준이 human dermal fibroblasts에서 ginsenoside Rg3에 의해 감소되었다. 이들 결과들은 ginsenoside Rg3이 fibroblasts에서 TGF-$\beta$1과 AP-1의 발현을 변화시킴으로써 type I collagen과 FN합성을 촉진시킴을 보여준다.
