  • 다양한 발효 균주를 이용한 잡곡발효음료 개발의 가능성을 확인하고자 7종의 균주와 2가지의 혼합균주를 이용하여 잡곡발효물을 제조하여 분석한 결과, 색도가 비교적 밝으며 붉은색보다는 노란색이 더 많이 측정되었다. 관능검사 결과, 종합적으로 C와 G, H가 상대적으로 높은 평가를 받았으며, 제조된 잡곡발효물의 세포독성은 10,000 ppm까지 관찰되지 않았다. 총 폴리페놀과 플라보노이드 함량에서 총 폴리페놀은 7.51~7.94 mg/g으로 모든 잡곡발효물에서 유사한 함량을 나타냈으나, 플라보노이드 함량은 C 샘플에서 15.62 mg/g으로 가장 많은 것으로 나타났다. 또한 잡곡발효물의 항산화 활성을 조사한 결과, 전자공여능에서는 C 샘플에서 4.48%로, 환원력에서는 G샘플이 0.247로 가장 높았으며, SOD 유사활성 측정에서는 E를 제외한 모든 샘플에서 농도 비례적으로 활성이 증가하였고, F 샘플 10,000 ppm에서 55.15%로 가장 높은 활성을 나타내었다. 이와 같이 다양한 균주를 이용한 발효물의 관능적 특성과 기능성을 검토함으로써 잡곡을 이용한 기능성 발효식품의 개발가능성을 제시하였다.

Red blood cell(RBC) SOD activities of KOG group was increased(F=3.619, p=0.052, ANOVA test), and RBC catalase activities of all experimental group were not significantly different. RBC GSH-px activities of KOG group was increased(F=6.844, p=0.008, ANOVA test). The changes of Plasma triglyceride was not significantly different. Plasma total lipid of KOG group showed significant decrease compared to the control group(F=19.337, p=0.0001, ANOVA test). Plasma total cholesterol and HDL-cholesterol concentrations of all experimental groups were not significantly different. Conclusions : According to the above results, it is considered that Kyungohkgo(瓊玉膏) is effective in inhibiting lipid peroxidation and increasing antioxidative enzyme activities in D-galactose induced aging rat.

  • Objective : Siegesbeckia Herba can treat various skin disease by expelling wind and removing dampness and clearing away heat and toxic material effects. This study was designed to investigate effects of Siegesbeckia Herba Extracts(SHE) on skin elasticity and whitening using B16F10 cell lines. Method : In this experiment, We observed effect of SHE on cell viability, inhibition of melanin synthesis and inhibitory effect on tyrosinase and elastase. Results : 1. SHE treated group showed decreased cell viability rates significantly compared with non-treated group. More than SHE $250{\mu}g/ml$, $500{\mu}g/ml$ and $1,000{\mu}g/ml$ of treated groups were lower levels of melanin synthesis respectively. 2. SHE significantly showed tyrosinase inhibitory activity in vitro, SHE increased tyrosinase inhibitory activity and elastase inhibitory activity in B16F10 cells, and tyrosinase inhibitory activity in vitro. 3. Tyrosinase inhibitory activity and elastase inhibitory activity in B16F10 cells, tyrosinase inhibitory activity in vitro were not accepted statistical significance compared with non-treated group. 4. SHE treated group showed increased SOD-like activity rates significantly compared with non-treated group. More than SHE $250{\mu}g/ml$, $500{\mu}g/ml$ and $1,000{\mu}g/ml$ of treated groups were lower levels of melanin synthesis respectively. Conclusion : These results suggest that SHE can inhibit melanin synthesis and tyrosinase inhibtory activity. So, We suggest that SHE can be maintained skin whitening.

  • Reactive Oxygen Species (ROS) are produced during normal cellular function. ROS are very transient species due to their high chemical reactivity that leads to lipid peroxidation and oxidation of some enzyme, massive protein oxidation and degradation. Under normal conditions, antioxidant are substances that either directly or indirectly protect cells against adverse effects of ROS. Several biologically important compounds have been reported to have antioxidant functions. These incluce vitamin C, vitamin E, GSH, flavonoids. superoxidee dismutase(SOD), glutathione peroxidase(GPX) and catalase(CAT). (omitted)

  • Adsorption of the pesticides (phosphamidon, fenitrothion, triadimefon and diniconazole) in natural zeolite (CL $I_{N}$) and several synthetic zeolites was incestigated. The pesticides were not adsorbed on zeolites (Na-Pl, SOD, ANA, JBW and CAN) synthesized from Jeju scoria. The distribution coefficient ( $K_{D}$) and the Freundlich constant ( $K_{F}$) decreased in the following sequences. FC $C_{W}$ (waste catalytic cracking catalyst)>FA $U_{F}$ (FAU Synthesized from coal fly ash)>(FAU+Na-Pl)$_{SF}$ (the mixture of FAU and Na-Pl synthesized from the ratio of Jeju scoria 6 to coal fly ash 4 by weight)>CL $I_{N}$ among the zeolites; diniconazole>fenitrothion> triadimefon>phosphamidon. As the temperature was increased, the amount of pesticide adsorbed per unit mass of zeolite increased for FC $C_{W}$, FA $U_{F}$ and (FAU+Na-Pl)$_{SF}$ but it decreased for CL $I_{N}$, for all the pesticides used in this study. It was independent of pH for phosphamidon, fenitrothion and triadimefon, but decresed as pH was increased for all the zeolites used in this study.y.udy.y.y.y.y.y.y.

  • It has been known that quercetin, a bioflavonoid widely distributed in fruits and vegetables as dietary-derived flavonoid and exert significant multiple biological effects such as antioxidant and anti-inflammatory, anti-tumor effects. In addition, it has been shown to have a chemoprotective role in cancer, though complex effects on signal transduction involved in cell proliferation and angiogenesis. The present study investigated whether quercetin can enhance antioxidant enzyme activity (glutathione peroxidase: GPx, superoxide dismutase: SOD, catalase: CAT) and regulate the reactive oxygen species (ROS) generation in the presence of vitamin E, L-ascorbic acid, reduced glutathione (GSH) on B16F10 murine melanoma cells. After 48h treatment of cells with quercetin in the presence of vitamin E, L-ascorbic acid, GSH, we measured the cytotoxicities by MTT assay. The cells exhibited a dose-dependent inhibition in their proliferation in the presence of vitamin E, L-ascorbic acid, GSH respectively. We also investigated the effects of antioxidant enzyme activity and ROS generation. The antioxidant enzyme activity of quercetin in the presence of vitamin E was stronger than GSH, L-ascorbic acid, the same treatments decreased ROS generation in B16F10 murine melanoma cells. Taken together, these result demonstrate that the antioxidant effect of quercetin can enhanced in the presence of vitamin E and it might plays an important role in anti-oxidative effects.

  • Objectives : The Objective of this study is to compare the anti-oxidative effect of the Hoveniae Semen cum Fructus (HScF) to that of Hoveniae Ramulus (HR) in vivo. Methods : The extracts of HScF and HR were tested in vivo for their anti-oxidative effects. SD Rats were injected with the AAPH (2.2'-azobis (2-aminodinopropane) hydrochloride) to induce the acute oxidization stress, and the oxidized rats were administered with the HScF and HR decoction orally. The RBC, WBC and PLT populations in plasma, and the blood chemistry levels of the rats were measured to observe the overall changes in the blood. The anti-oxidative effects of the HScF and HR decoctions were investigated on the liver tissues of the oxidated rats. Results : 1. Thrombocyte decreased significantly in the group medicated with HScF. 2. Blood glucose increased significantly in the group medicated with HR. 3. SOD activity increased significantly in both the group medicated with HScF and that with HR. 4. NO concentration decreased significantly in both the group medicated with HScF and that with HR. 5. The catalase content increased significantly in both the group medicated with HScF and that with HR. Conclusions : The HScF and HR extracts have an anti-oxidative effect.

  • 유근피 추출물을 20주간 장기 복용한 B6C3F1 마우스의 신장에서 노화 및 생체 독성의 중요한 지표로 알려진 반응성 산소종 발생 및 제거에 관여하는 효소들의 활성 현화를 관찰하였다. 실험군을 1군(대조군), 2군(암유발군-DEN을 주사하여 암유발), 3군(유근피 복용군), 4군(유근피 암치료군-DEN을 주사한 후 유근피복용), 5군(유근피 암예방군-유근피를 먹이면서 DEN 주사)등 5개군으로 나누었다. 암을 유발시킨 군에 유근피 추출물을 투여시 4군 및 5군에서 암유발군에 비해 유의적(p<0.01)으로 감소된 xanthine oxidase 효소활성을 확인하였다. Cu,Zn-SOD의 활성도는 정상군과 처리군에서 큰 차이는 없으나 Mn-SOD의 활성도는 정상군보다 암유발군에서 유의적으로 증가하는 경향을 보였다. 암유발군(2군)과 유근피 암치료군(4군)은 대조군 보다 catalase 효소이 낮았으며, 유근피 암예방군(5군)에서는 암유발군(2군)보다 catalase 활성도가 높은 것으로 나타났다. 암유발군(2군)에서는 glutathione peroxidase의 활성이 감소하는 것으로 나타났으며, 발암물질 처리와 동시에 유근피 추출물을 처리한 유근피 암예방군(5군)에서는 기타 실험군에 비해 효소활성이 매우 증가하는 것으로 (p<0.01) 나타났다. 대조군(1군)에 비해 암유발군(2군)에서 지질의 과산화도는 매우 증가하는 것으로 나타났으며, 유근피 복용군(3군)에서도 유의적으로 증가(p<0.05)하는 경향을 나타내었다. 그러나 암발생 후 유근피 추출물 식이군인 유근피 암치료군(4군)과 암발생과 동시에 유근피 추출물을 식이한 유근피 암예방군(5군)의 경우 암유발군(2군)보다 지질의 산화도가 낮은 것으로 나타났다.
