A total of 251 clinical isolates (human origin, 43 strains and bovine udder origin 208 strains) of the Staphylococcus that fermented mannitol aerobically were tested for their ability to produce coagulase, DNase, and thermostable nuclease. Of these, 158 isolates coagulated human or bovine plasma, produced DNase, and thermostable, nuclease and were identified as St. aureous, 146 of which produced a 1+ to 3+ clot. The remaining 12 isolated produced a -clot in citrate treated plasma but produced 1+ to 3+ clot in ethylenedi-aminetetraacetic acid (EDTA) treated plasma. It was found that 7 coagulase positive isolates failed to produced thermostable nuclease. In these organisms, we found out of the clot formation is not by coagulase activity but utilization of citrate, because EDTA treated plasma is not coagulated. Among 93 isolates which did not coagulate citrate-or EDTA treated plasma and thermostable nuclease negative, 28 strains produced DNase were identified as St. epidermidis, and other strains were not identification further. It was found that thermostable nuclese production appears to be a consistent property of St. aureus and the test is easy to perform, is rapid became quite distinct within 2 to 4 hour, and is not influenced by as many factors and variations as the coagulase test.

In this study, we used the mixture made from the Rice bran 45 ㎏, Dendropanax 5 ㎏, the sugar of the 10% of the total weight, and the enzyme of the 0.1% of the total weight. After the mixture were fermented for 90 days under 20 $^{\circ}C$, we measured the cell viability and the inhibition rate of the melanin biosynthesis, the activity of tyrosinase and superoxide dismutase (SOD) in malignant melanoma, B16F10 cells, in order to survey the whitening effect and the mechanism of the effects on the sample. As a result, the samples significantly suppressed the cell viability of B16F10 in more than 500 ${{\mu}g}$/㎖ and significantly inhibited the generation of melanin induced by ${\alpha}$-MSH in more than 1,000 ${{\mu}g}$/㎖. Sample decreased the activity of tyrosinase while increased the activity of SOD in dose dependent manner. Therefore, we considered that the fermentation extract made from a Rice bran and Dendropanax will be able to produce high value-added products, if used as a commercial.

Obesity is associated with numerous diseases such as type 2 diabetes, hypertension and cancer. Inhibition of adipogenesis is a effectite strategy to anti-obesity. In this study, Galla Chinenisis extract (GCE) inhibited adipocyte differentiation in OP9 cells. There was no cytotoxicity when cells were treated with GCE in designated time intervals, unaffected by concentration. In this cell model, increases in fat storage were inhibited by 2 days treatment with various concentration of GCE, visualized by Oil red-O, BODIPY and DAPI staining. To understand the underlying mechanism at the molecular level, the effects of GCE were examined on the expression of the genes involved in adipogenesis by real-time PCR. In the progress of adipocyte differentiation with GCE-treated, the mRNA level of adipogenic genes such as peroxisome-proliferator-activated receptors gamma ($PPAR{\gamma}$), computer-assisted axial tomography/enhancer binding protein-alpha ($C/EBP{\alpha}$) were decreased. Also, GCE treatment inhibited increase of mRNA expression, which is adipogenic factor such as fatty acid synthase (FAS), hormone-sensitve lipase (HSL), lipoprotein lipase (LPL), and adipocyte-specific lipid binding protein (aP2). Therefore, the result of this study suggest that Galla Chinenisis extract can prevent adipocyte differentiation and GCE may have a great potential as a novel anti-adipogenic agent.

Atopic dermatitis symptoms were improved in HYGBH treated group and significant decrease in dermatitis index were observed in 12 and 14 weeks. HYGBH treated group showed significant decrease in CD4+, CD3+/CD69+ immune cell ratio in PBMC by 18% and 40.6% respectively. HYGBH treated group showed significant decrease in CD3+, CD11b+/Gr-1+ immune cell ratio in dorsal skin by 44.6% and 53.1% respectively. HYGBH treated group showed significant decrease in IL-4, IFN-${\gamma}$ in spleen by 29.5%, 7.7% respectively. HYGBH treated group showed decrease in the expression of IL-5, IL-13, IL-17 and histamine by 21%, 9.6%, 14%, and 32.2% respectively. Also the group showed decrease in the expression of IgE by 6.8% respectively. HYGBH treated group showed significant decrease in the transcription of IL-5 and IL-3 mRNA in skin by 35.5% and 23.2% respectively. The results above indicated that treatment of HYGBH improved atopic dermatitis symptoms by anti-oxidant activity as well as immune modulation activity as a clinical evidence. Also, to increase the application of fermented oriental medicine, different fermentation conditions using various microbial strains should be accumulated as the clinical evidence in the future.

본 연구에서는 노란콩과 검은콩의 메탄올 추출물과 각각의 콩으로부터 제조된 된장 메탄올 추출물이 IL-2, IL-6 및 TNF-${\alpha}$를 포함하는 사이토카인의 생성과 종양전이 억제에 미치는 영향에 대해 검토하였다. IL-2의 경우, LPS를 처리하지 않았을 때 대조군과 2개월 발효 검은콩 된장 메탄올 추출물 (10 ${\mu}g$/ml)에서 가장 높은 IL-2 생성을 나타내었고 LPS (1 ${\mu}g$/ml)를 처리한 후에는 검은콩 메탄올 추출물에서 가장 높은 IL-2 생성을 보였고 대조군에서 가장 낮은 생성을 나타내었다(p<0.05). 또한 IL-6 생성의 경우 LPS를 처리하지 않았을 때 2개월 발효 검은콩 된장 메탄올 추출물(10 ${\mu}g$/ml)에서 가장 높은 수치를 나타내었고 대조군과 2개월 발효된 노란콩 된장 메탄올 추출물(10 ${\mu}g$/ml)에서 가장 낮았다(p<0.05). LPS (1 ${\mu}g$/ml)를 처리한 경우, 대조군, 노란콩, 2개월 및 7개월 발효된 검은콩 메탄올 추출물(10 ${\mu}g$/ml)에서 검은콩 및 2개월 발효된 노란콩 된장 메탄올 추출물(10 ${\mu}g$/ml)에서 보다 유의적으로 높은 수치를 나타내었다(p<0.05). TNF-${\alpha}$의 생성에서 2개월 발효된 검은콩 메탄올 추출물(10 ${\mu}g$/ml)은 LPS를 처리하지 않을 때와 LPS (1 ${\mu}g$/ml)를 처리한 후 둘다의 경우 기타 실험군들에 비해 유의적으로 높은 TNF-${\alpha}$의 Journal of Life Science 2009, Vol. 19. No. 2 269 생성을 나타내었다(p<0.05). 한편 종양전이의 예방적 효과에 대한 실험결과에서 1 mg/mouse 농도로 투여하였을 때 2개월 발효된 노란콩 된장, 검은콩, 2개월 검은콩 된장, 7개월 검은콩 된장에서 각각 18%, 26%, 21%, 50%로 7개월 발효된 검은콩 된장에서 종양전이를 크게 억제하는 것으로 나타났다. 따라서 검은콩으로 제조한 된장은 사이토카인 생성을 증가시켜 면역증진 활성을 나타내었으며 암전이의 예방효과도 우수하였음을 확인할 수 있었다.

Fibrin clots of blood vessels are one of the serious factor caused cardiovascular disease. The development of a antithrombotic and thrombolysis solvent is necessary to prevent and treat these diseases. It has been reported that a strong fibrin-specific fibrinolytic enzyme was produced from a Korean fermented soybean paste similar to Japanese miso. We have been screened the known or novel fibrinolytic enzymes by activity-based and sequence-based screening from soil DNA metagenome library containing all kinds of environmental genomic DNA. The activity-based screening was determined the protease activity on 0.5% skim milk. For sequence-based screening, we designed a set of primer expanding gene sequence of fibrinolytic enzyme, performed PCR and selected clones showing the expected size of amplicons from metagenome library. Transformation of the gene encoding fibrinolytic enzyme was carried out with commercial vectors and their transformants were selected. Finally, we found 15 positive clones from metagenome library. Then each of sequences were analyzed and identified as similar or known the clones of nattokinase. We are going to perform full sequence of each clones, ligate with expression vector, transform into competent cells and then determine activity of expressed enzymes.
