Aim: The present investigation was to evaluate the effects of essential oils of Wedelia chinensis (Osbeck) on free radicals and in vivo antioxidant properties. Methods: Essential oils were extracted using hydro-distillation and compound analysis was performed by GC-MS analysis. Screening for inhibitory activity was conducted by DPPH and OH-scavenging assays. In addition an in vivo study was carried out in cell line implanted cancer bearing mice with assessment of levels of catalase, superoxide dismutase, glutathione peroxidase, lipid peroxidation, nitric oxide and reduced glutathione. Finally, lungs were dissected out for histopathology study of metastasis. Results: GC-MS analysis revealed the presence of carvocrol and trans-caryophyllene as the major compounds with 96% comparison with the Wilily and NBS libraries. The essential oil exhibited significant inhibition in DPPH free radical formation. Whereas reducing power and hydroxyl radical scavenging activity are dose dependent. When compared with the standard, it was found that the essential oil has more or less equal activity in scavenging free radicals produced. In the animal studies, the level of antioxidant enzymes catalase, superoxide dismutase and glutathione peroxidase, as well as glutathione, were found to be increased in treated groups whereas lipid peroxidation and nitric oxide were reduced. Histopathology report also shows that the essential oil has a significant combating effect against cancer development. Conclusion: In all the in vitro assays, a significant correlation existed between the concentrations of the essential oil and percentage inhibition of free radicals. The in vivo studies also has shown a very good antioxidant property for the essential oil during cancer development. From, these results the essential oil can be recommended for treating disease related to free radicals and to prevent cancer development.

식중독 병원균인 장염비브리오균 (V. parahaemolyticus)의 세포외 분비 효소 중 콜라겐분해효소를 발현벡터인 pET-29b에 클로닝시키고 대장균에서 발현시킨 다음, 부분정제하여 그 특성을 조사하였다. V. parahaemolyticus collagenase는 $(NH_4)_2So_4$침전, affinity adsorption, 그리고 Sephacryl S-100 gel filtration 과정을 통하여 부분정제 되었다. 이 collagenase는 73%의 회수율과 43.7의 정제도를 나타내었으며, 전기영동시 분자량은 약 35 kDa로 나타났다. 이 효소의 최적 pH 및 온도는 6~12와 $35^{\circ}C$이었고, 온도안정성 조사에서 $55^{\circ}C$까지는 90% 잔존 찬성을 유지하였으나 $60^{\circ}C$이상에서는 급격하게 효소활성이 실활되었다. 기질특이성조사에서 type I collagen과 콜라겐분해효소의 합성기질로 알려진 Z-GPGGPA에서 gelatin과 casein에 비해 높은 활성을 보이는 것으로 보아 이 효소가 진정한 콜라겐분해효소라는 것을 알 수 있었다.

BACKGROUND/OBJECTIVES: Docosahexaenoic acid (DHA), an n-3 long chain polyunsaturated fatty acid (LCPUFA), is acquired by dietary intake or the in vivo conversion of ${\alpha}$-linolenic acid. Many enzymes participating in LCPUFA synthesis are regulated by peroxisome proliferator-activated receptor alpha ($PPAR{\alpha}$). Therefore, it was hypothesized that the tissue accretion of endogenously synthesized DHA could be modified by $PPAR{\alpha}$. MATERIALS/METHODS: The tissue DHA concentrations and mRNA levels of genes participating in DHA biosynthesis were compared among $PPAR{\alpha}$ homozygous (KO), heterozygous (HZ), and wild type (WT) mice (Exp I), and between WT mice treated with clofibrate ($PPAR{\alpha}$ agonist) or those not treated (Exp II). In ExpII, the expression levels of the proteins associated with DHA function in the brain cortex and retina were also measured. An n3-PUFA depleted/replenished regimen was applied to mitigate the confounding effects of maternal DHA. RESULTS: $PPAR{\alpha}$ ablation reduced the hepatic Acox, Fads1, and Fads2 mRNA levels, as well as the DHA concentration in the liver, but not in the brain cortex. In contrast, $PPAR{\alpha}$ activation increased hepatic Acox, Fads1, Fads2, and Elovl5 mRNA levels, but reduced the DHA concentrations in the liver, retina, and phospholipid of brain cortex, and decreased mRNA and protein levels of the brain-derived neurotrophic factor in brain cortex. CONCLUSIONS: LCPUFA enzyme expression was altered by $PPAR{\alpha}$. Either $PPAR{\alpha}$ deficiency or activation-decreased tissue DHA concentration is a stimulus for further studies to determine the functional significance.

Background: Dendritic cell (DC)-based cancer immunotherapy is studied for several years. However, it is mainly derived from autologous PBMC or leukapheresis from patient, which has limitations about yield and ability of DC production according to individual status. In order to solve these problems, inquiries about allogeneic DCs are performed but there are no preclinical trial answers for effect or toxicity of allogeneic DC to use for clinical trial. In this study, we compared the anti-tumor effect of allogeneic and autologous DCs from mouse bone marrow stem cells in mouse metastatic melanoma model. Methods: B16F10 melanoma cells ($5{\times}10^4$/mouse) were injected intravenously into the C57BL/6 mouse. Therapeutic DCs were differentiated from autologous (C57BL/6: CDC) or allogeneic (B6C3F1: BDC) bone marrow stem cells with GM-CSF, SCF and IL-4 for 13days and pulsed with B16F10 tumor cell lysate (Blys) for 18hrs. DC intra-peritoneal injections began on the 8th day after the tumor cell injection by twice with one week interval. Results: Anti-tumor response was observed by DC treatment without any toxicity especially in allogeneic DC treated mice (tumor burden score: $2.667{\pm}0.184,\;2.500{\pm}0.463,\;2.000{\pm}0.286,\;1.500{\pm}0.286,\;1.667 {\pm}0.297$ for saline, CDC/unpulsed-DC: U-DC, CDC/Blys-DC, BDC/U-DC and BDC/Blys-DC, respectively). IFN-${\gamma}$ secretion was significantly increased in allogeneic DC group stimulated with B16F10 cell lysate ($2,643.3{\pm}5,89.7,\;8,561.5{\pm}2,204.9.\;6,901.2{\pm}141.1pg/1{\times}10^6$ cells for saline, BDC/U-DC and BDC/Blys-DC, respectively) with increased NK cell activity. Conclusion: Conclusively, promising data was obtained that allogeneic DC can be used for DC-based cancer immunotherapy.
