Objectives： Arachidonic acid is control the thromboxane A2 (TXA2) and prostacycline (PGI2) synthesis, TXA2 increase lead to thrombus produced by induces platelet aggregation and vasoconstriction. Angelicae gigantis radix (RAR) is mainly used blood deficiency and stagnation. In previous studies, RAR has been reported that a vasodilating and blood clotting delay effects. In this study, investigate that anti-oxidant and anti-thrombotic effects of RAR by heat-process.Methods： The heated angelicae gigantis radix sample were made by 140, 180, and 220 ℃ and 4, 6, 9 and 12 min using water or 30% ethanol. The anti-oxidant effects were measured by total polyphenol, total flavonoid, DPPH and ABTS radical scavening activation. Anti-thrombotic effect conducted in samples that are determined to be effective through the anti-oxidant experiment such as angelicae gigantis radix roasted 180℃, and 220℃ and angelicae gigantis radix roasted with 30% ethanol 180℃, and 220℃.Results： Anti-oxidant parameters were efficacious in high temperature roasted AR. Also AR and EAR increased a inhibitory activity of FXa compared with RAR. The blood coagulation time of administration groups were significantly increased compare with control group. The TXB2 was significantly decreased in AR and EAR.Conclusions : We confirmed that whether AR and EAR administration has anti-oxidant and anti-thrombotic effect or not. As the results, AR and EAR were improved anti-oxidant effects and blood biochemistry compare with control group. This study provides scientific evidence that AR and EAR are have an anti-oxidant effect and anti-thrombotic effect, it expected that there is no difference between the two.

Objectives : The aim of experiment is to examine anti-inflammatory effect and anti-oxidant effect of Naesohwangryun-tang (NSHRT) in LPS-stimulated RAW264.7 macrophage cells. Methods : In the present study, The cell viability was performed by MTT assay. Nitric oxide (NO) production and prostaglandin E₂ (PGE₂) synthesis were performed by NO assay and ELISA KIT. The anti-oxidant effect was performed by DPPH and ABTS radical scavenging activity. The inhibitory effects of pro-inflammatory mediators and cytokines were confirmed by realtime PCR and western blotting. Results : NSHRT was no cytotoxicity at treated group. NO and PGE2 production were inhibited compared to the LPS treated group and also mRNA and protein expressions were significantly decreased compared to the LPS treated group. Conclusions : According to the above experiments, we confirmed that NSHRT has anti-inflammatory and anti-oxidant effects. It is suggested that NSHRT is potential ingredient of skin diseases.

Objectives : Allium hookeri is a well-known traditional herbal remedy and its root used for treatment of inflammation and tumor. However, the mechanism of anti-inflammatory effect of Allium hookeri is still unknown. This study aims to examine the mechanism of anti-inflammatory effect of Allium hookeri on mouse macrophage cell line, RAW 264.7 cells. Methods : Anti-oxidant effect of water extract of Allium hookeri (WEAH) was measured by 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) assay. 3- (4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay was performed to determine the effect of WEAH on cell viability in RAW 264.7 cells. In addition, anti-inflammatory effect of WEAH was investigated in RAW 264.7 cells. Inflammation of RAW 264.7 cells induced by lipopolysarccharide (LPS) treatment and expression levels of inflammatory cytokine interleukin 1 β (IL-1β) and interleukin 6 (IL-6) gene were analyzed using quantitative reverse transcription PCR (qRT-PCR) analysis. Furthermore, the phosphorylation of inhibitor of nuclear factor kappa B (IκBα) after LPS treatment with WEAH-treated RAW 264.7 cells was confirmed by immunoblot analysis. Results : WEAH showed a strong anti-oxidant effect and no cytotoxicity to RAW 264.7 cells up to 2 mg/㎖ concentration. The LPS-induced mRNA expression levels of IL-1β and IL-6 were decreased by WEAH treatment. Furthermore, the LPS-induced phosphorylation of IκBα is attenuated by WEAH treatment. Conclusions : Through experimental demonstration of anti-oxidant and anti-inflammatory effects of WEAH, we suggest that Allium hookeri is a valuable material for prevention and treatment of various inflammatory diseases.

This study was carried out to investigate the anti-oxidant effect of Wasabia japonica(WJ). The anti-oxidant activities of various extracts from WJ were investigated. The water and ethanol extracts of WJ leaf were found to cause significant free radical scavenging effects on DPPH and nitric oxide(NO). Sprague-Dawley male rats were randomly assigned to one normal diet and three high cholesterol diet groups which contained 1%(w/w) cholesterol. After 4weeks cholesterol diet, the groups of high cholesterol diet were classified to control(normal diet only), WJR5(normal diet and 5% WJ root) and WJL5(normal diet and 5% WJ leaf). Liver xanthine oxidase(XO) activity in the rats of high cholesterol diet was decreased up to the levels of normal diet group according to WJ diet. The results indicated that WJ possesses antioxidant effects through free radical scavenging effects on DPPH, NO and the decreasing of XO activity. In view of these results, WJ is expected to be an effective material for the anti-oxidant.

Background and Objectives : The aim of this study was to investigate the anti-oxidant, anti-allergic and anti-inflammatory ability of the Taglisodog-eum(SHE) extract on the RAW 264.7 and EL4 cells Materials and Methods : Three types of experiments were implemented for this study: first, the experiment to study the anti-oxidant effect of SHE using Riboflavin; second, in vitro experiment to investigate the inhibition of Th 2 cell differentiation by SHE using EL4 cells (IL-4 mRNA expression); third, the suppression of $NF-{\kappa}B$ activation using RAW 264.7 cells (iNOS and COX-2 mRNA expression). Results : The anti-oxidant ability of SHE were dose-dependantly increased. From in vitro, the LPS-induced iNOS and COX-2 mRNA expression were dose-dependantly decreased in the RAW264.7 cells treated with SHE and the PMA-induced IL-4 mRNA expression were also dose-dependantly decreased in EL4 cells. $NF-{\kappa}B$ activation was suppressed, and iNOS & COX-2 production were inhibited by SHE Conclusion : The results suggest that SHE has dose-dependant anti-oxidant ability, and has anti-allergic and anti-inflammatory effects through the suppression of $NF-{\kappa}B$ activation and the inhibition of Th 2 cell differentiation.
