  • The molecular mechanisms by which a variety of naturally-occurring dietary compounds exert chemopreventive effects have been a subject of intense scientific investigations. Induction of phase II detoxification and anti-oxidant enzymes through activation of Nrf2/ARE-dependent gene is recognized as one of the major cellular defense mechanisms against oxidative or xenobiotic stresses and currently represents a critical chemopreventive mechanism of action. In the present review, the functional significance of Keap1/Nrf2 protein module in regulating ARE-dependent phase II detoxification and anti-oxidant gene expression is discussed. The biochemical mechanisms underlying the phosphorylation and expression of Keap1/Nrf2 proteins that are controlled by the intracellular signaling kinases and ubiquitin-mediated E3 ligase system as well as control of nucleocytoplasmic translocation of Nrf2 by its innate nuclear export signal (NES) are described.

  • The purpose of this study is verification of the anti-oxidant effect and anti-inflammatory effect of Eggplant-cheongyeolsodokum composed of 8 herbs (Solanum melongena L., Lonicera japonica Thunb., Glycyrrhiza uralensis Fisch., Ligusticum chuanxiong Hort., Angelica gigas Nakai., Coptis deltoidea C. Y. Cheng et Hsiao., Gardenia jasminoides J. Ellis., Forsythia suspensa Vahl) to confirm the possibilities as useful cosmetic material. We used the modified prescription of 'cheongyeolsodokum' contained in Korean traditional medical book 'Donguibogam' as composition of Eggplant-cheongyeolsodokum and their proportions. Eggplant-cheongyeolsodokum were extracted with hot water, 70% ethanol and then powdered. To confirm anti-oxidant effect, we investigated radical scavenging ability (DPPH, $ABTS^+$, superoxide), superoxide dismutase (SOD)-like activity, total polyphenolic contents. Also to confirm anti-inflammatory effect, we investigated inhibition effect of nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages, and Inhibition effect of the expression of inflammatory-related proteins (iNOS, COX-2) by western blot analysis. As a result, Eggplant-cheongyeolsodokum showed good anti-oxidant and anti-inflammation effects, we suggest that it can be used as an active ingredient for cosmetics.

  • Objectives : The aim of this study was to examine effect of anti-oxidant and anti-inflammation activity of the Kyeongok-go with various processing methods that was manufactured by heating mantle. Methods : Commercial Kyeongok-go (K0) was purchased and Kyeongok-go with ginseng (K1), Kyeongok-go with black ginseng (BK), ginseng fermentation Kyeongok-go (KF), black ginseng fermentation Kyeongok-go (BKF) were manufactured by heating mantle. To examine anti-oxidant effect, DPPH radical and production of NO and ROS in RAW 264.74 cell were used. Furthermore, to determined anti-inflammation effect, measured pro-inflammatory mRNA such as NOS-II, COX-2, $IL-1{\beta}$, IL-6, $TNF-{\alpha}$ in RAW 264.74 cell treated with K0, K1, KF, BK, and BKF. Result : K1 scavenged DPPH radical effectively than K0. The most DPPH radical scavenging activity was BKF. In the RAW 264.74 cells stimulated with LPS, NO and ROS production were measured. As a results, K1 was decreased NO, ROS production compared with K0, and BKF was reduced similarly to cyclosporine A (positive control). Expression of pro-inflammatory mRNA such as NOS-II, COX-2, $IL-1{\beta}$, IL-6 showed a significant decrease in BK or BKF. But, there was no significant in expression of $TNF-{\alpha}$ in all extract treatmetn groups. Conclusions : According to the above results, it is considered that Kyeongok-go with fermented black ginseng (BKF) manufactured by heating mantle is effective material that have anti-inflammation and anti-oxidant activities. Our finding indicate that BKF may be an effective agent for anti-inflammation through anti-oxidant effect.

  • Chenopodium album Linne (CAL) is a fast-growing weedy annual plant. The leaves and young shoots may be eaten as a leafy vegetable. In oriental medicine, CAL has been used for treatment of skin disease, fever, stomach ache, toothache, and paralysis. After a preliminary screening of CAL ethanol extract and its fractions obtained from CAL leaves for anti-gastritic and anti-Helicobacter pylori (H. pylori) activity, the butanol (BuOH) fraction was found to have the most significant effect. We also examined antioxidative properties of the total CAL extract and its fractions, and also betaine as an ingredient of the BuOH fraction. To investigate the antioxidant effects of CAL on gastritis, the reducing power, free radical scavenging activity using 1,1-diphenyl-2-picrylhydrazyl (DPPH), and lipid peroxidation effects were determined. Additionally, the BuOH fraction reduced cell viability in a concentration dependent manner in human gastric cancer cell lines. The results of this study revealed that CAL has excellent antioxidant activity, and may be useful in treating gastritis and gastric cancer.

  • This study aimed to observe the effects of Sea Buckthorn seed extracts (SEB) on anti-oxidation and antiinflammation. SEB were found to strongly depress ROS production depending on concentration, and 46.5% anti-oxidation effects were found in the top concentration of 100 ${\mu}g/mL$. Histamine and arachidonic acid release were measured to observe the effects of SEB on anti-inflammation. SEB inhibited histamine release and arachidonic acid release on dose dependent manner. Based on the results above, the conclusion is drawn that SEB have the potential to be used as natural materials that are effective for anti-oxidation and antiinflammation.

  • Rhus verniciflua Stokes (RVS) has been used as a traditional herbal medicine. Several earlier studies indicated that an ethanol extract of RVS has both anti-oxidant and anti-tumor properties, although the mechanism for the activity remains to be elucidated. In this report, we prepared a highly purified ethanol extract from RVS, named REEE-1 ($\underline{R}$hus $\underline{e}$thanol $\underline{e}$luted $\underline{e}$xtract-1), and investigated the mechanism involved in its growth-inhibitory effect on the human B and T lymphoma cell lines, BJAB and Jurkat, respectively. Results from tritium uptake proliferation assays showed that the proliferative capacities of both BJAB and Jurkat cells were strongly suppressed in the presence of REEE-1. This was further confirmed through trypan blue exclusion experiments that revealed a dose-dependent decrease in viable cell numbers after REEE-1 treatment. REEE-1-mediated suppression of cell growth was verified to be apoptotic, based on the increase in DNA fragmentation, low fluorescence intensity in nuclei after propidium iodide staining, and the appearance of DNA laddering. In particular, REEE-1 exerted its anti-oxidant activity through the inhibition of hydroxyl radical-mediated degradation by iron ion chelation rather than direct scavenging of hydroxyl radicals. Furthermore, REEE-1 was revealed to be a potential scavenger of superoxide anions. Collectively, our findings suggest that REEE-1 is a natural anti-oxidant that could be used as a cancer chemo-preventive and therapeutic agent.

  • It is recognized that Perilla frutescens L. (PfL) are useful for various diseases, including allergic disorders. To evaluate whether the PfL extract have potential in alleviating oxidant and inflammatory process, some in vitro antioxidant assays and in vivo DNFB-induced atopic assay were investigated. Extracts of PfL have potent anti-oxidant activity by DPPH or FRAP assay. By treatment of high temperature / high pressure extraction process of PfL seed, the activity was increased. Using a mouse animal model, we found that PfL extract reduces ear thickness and epithelial thickening and infiltration of immune cells inhibition. Collectively, the present results suggest that PfL can be used as an antioxidant and/or anti-inflammatory biomaterial, that should be proved to evaluate on mechanistic study and development of functional food.
