Objectives The purpose of this study was to investigate the Anti-oxidation and anti-inflammatory effects of ethanol extract from asiasari radix (AR) on lipopolysaccharide (LPS)-induced in RAW 264.7 Cells Methods Anti-oxidative effects of AR were measured by scavenging activities of 1,1-diphenyl-2-picryl-hydrazyl (DPPH), 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and production of reactive oxygen species (ROS) in RAW 264.7 cells. Anti-inflammatory effects of AR were measured by mediators including nitric oxide(NO), interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), tumor necosis factors-${\alpha}$ (TNF-${\alpha}$) and iNOS, IL-$1{\beta}$, IL-6, TNF-${\alpha}$ mRNA expression in RAW 264.7 cells. Results Total phenolic content was expressed $28.77{\pm}1.67$. DPPH radical Scavenging was increased depend on AR ethanol extract. ABAT radical Scavenging was increased depend on AR ethanol extract. Production of ROS was significantly decreased by AR ethanol extract on concentration of 100 (${\mu}g/ml$). Production of NO was significantly decreased by AR ethanol extract on concentration of $100({\mu}g/ml)$. Production of IL-$1{\beta}$, interleukin-6 and TNF-${\alpha}$ were increased depend on AR ethanol extract. And Production of interleukin-6, TNF-${\alpha}$ were significantly decreased AR ethanol extract. iNOS, IL-$1{\beta}$, IL-6, TNF-${\alpha}$ mRNA expression of RAW 264.7 cells was increased depend on AR ethanol extract.

Objectives This study was designed to investigate whether the Cheongajihwang-Tang (CT) has an inhibitory effect association with oxidation or inflammation in RAW264.7 cells. Methods Cytotoxic activity of CT extract on RAW264.7 cells was evaluated by using 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide (MTT) solution. Nitric oxide production was measured using Griess reagent system. The total phenolic contents and 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity was measured to evaluate the anti-oxidative effects of CT. Dichlorofluorescin diacetate (DCFH-DA) has been used as a substrate for measuring intracellular oxidant production. Results Cheongajihwang-Tang does not impair the cell viability in tested concentration. CT showed anti-oxidative effects in vitro by decreasing electron donating ability, and also showed anti-inflammatory effects suppressing NO and ROS expression in LPS induced RAW264.7 activation. CT inhibited the generation of intracellular ROS production as dose dependant manner. Conclusions CT has anti-oxidative effects and anti-inflammatory activities. These results indicate that CT extract has an anti-inflammatory activities via anti-oxidative effects.

Objective : This study was performed to compare anti-inflammation, anti-oxidation and anti-bacterial effects of Cuscutae Semen(CS) extracted with two kinds of solvents, ethanol and distilled water. Methods : Two kinds of CS extractions were prepared 20, 50, 100 ${\mu}l/mg$. The cytotoxicity was measured by MTT assay in Raw 264.7 cell. The anti-inflammation effect was measured by inhibitory efficacy of NO Production in Raw 264.7 cell. The anti-oxidation effect was measured by DPPH Radical scavenging ability in HaCaT cell. The anti-bacterial effect was measured by inhibition zone diameter on Propionibacterium acnes. Results : 1. Two kinds(100 ${\mu}l/mg$) of CS extraction groups had 50% cytotoxicity in Raw 264.7 cell. 2. All of CS extraction groups were not showed significantly inhibitory effect on NO production. 3. All of CS extracted with ethanol only showed dose-dependently significantly scavenging effect of DPPH radicals. 4. Two kinds of CS extractions did not have a inhibitory effect on Propionibactrium acnes. Conclusion : Two kinds(100 ${\mu}l/mg$) of CS extraction groups have 50% cytotoxicity. Two kinds of CS extractions have not the inhibitory effect on NO production and Propionibactrium acnes. CS groups extracted with ethanol only have a significantly scavenging ability of DPPH radicals. This study suggests that CS extracted with ethanol was effective in anti-oxidation.

[Purpose] While the anti-obesity effects of exercise and capsiate are well-observed individually, the effect of exercise with capsiate intake has not been systematically explored yet. Therefore, the purpose of this study is to investigate whether the anti-obesity effects of exercise training can be further enhanced by capsiate intake. [Methods] 8-week-old male mice were divided into 3 groups (n = 8 per group): sedentary group (SED; nontrained), exercise-trained group (EXE) and exercise-trained group with 10 mg/kg of capsiate intake (EXE+CAP). All mice were offered high-fat diet and water ad libitum. The mild-intensity treadmill training was conducted 5 times a week for 8 weeks. After 8 weeks, metabolism during exercise and abdominal fat weight were measured. [Results] Body weight and the rate of total abdominal fat were significantly less in EXE+CAP than in SED but not between EXE and SED. The average of respiratory exchange rate during exercise was significantly much lower in EXE+SED (p = 0.003) compared to the difference between EXE and SED (p = 0.025). Likewise, the fat oxidation during exercise was significantly much higher in EXE+SED (p = 0.016) compared to the difference between EXE and SED (p = 0.045). Then, the carbohydrate oxidation during exercise was significantly much lower in EXE+SED (p = 0.003) compared to the difference between EXE and SED (p = 0.028). [Conclusion] In conclusion, the anti-obesity functions of exercise training can be further enhanced by capsiate intake by increasing fat oxidation during exercise. Therefore, we suggest that capsiate could be a candidate supplement which can additively ameliorate obesity when combined with exercise.

Stainless steels are alloy steels with a nominal chromium content of at least 11 percent, with other alloy additions. The stainlessness and corrosion resistance of these alloy steels are attributed to the presence of a passive oxide film on the surface. When exposed to conditions like Resistance Spot Welding (RSW) process that remove the passive oxide film, stainless steels are subject to corrosive attack. And exposure to elevated temperatures causes oxidation (discoloration) of areas around indentation in Spot welding. In this paper, deal with the effect of shielding gas (Ar) preventing the corrosion, oxidation of stainless steel. And find the optimal shielding gas flow rate. In addition, suggest effective purging method for direct/indirect spot welding process.

Objective : The purpose of this study was to establish the simultaneous analysis for six compounds in Gumiganghwal-tang (GMGHT, Jiuweiqianghuo-tang) and to investigate the anti-atherosclerotic effects of GMGHT in vitro. Methods : The column for separation of six compounds was used Luna $C_{18}$ column and maintained at $40^{\circ}C$. The mobile phase for gradient elution consisted of two solvent systems, 1.0% acetic acid in water and 1.0% acetic acid in acetonitrile. The analysis was carried out at a flow rate of 1.0 mL/min with pothodiode array (PDA) detection at 254, 280, and 320 nm. The injection volume was 10 ${\mu}L$. The antioxidant activities of GMGHT were evaluated by measuring free radical scavenging activities on 2,2'-Azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) and 1-1-diphenyl-2-picrylhydrazyl (DPPH). The inhibitory effects on low-density lipoprotein (LDL) oxidation were evaluated by the formation of thiobarbituric acid relative substances (TBARS), relative electrophoretic mobility (REM), and fragmentation of apolipoprotein B (ApoB)-100. Results : Calibration curves were acquired with $r^2{\geq}0.9998$. The contents of liquiritin, ferulic acid, baicalin, baicalein, glycyrrhizin, and wogonin in GMGHT were 1.784, 1.693, 37.899, 0.258, 1.869, and 0.034 mg/g, respectively. The GMGHT showed the radical scavenging activity in a dose-dependent manner. The concentration required for 50% reduction ($RC_{50}$) against ABTS and DPPH radicals were 72.51 ${\mu}g/mL$ and 128.49 ${\mu}g/mL$. Furthermore, GMGHT reduced the oxidation properties of LDL induced by $CuSO_4$. Conclusion : HPLC-PDA is considered as an available and convenient method for quality control and standardization of GMGH and GMGHT has potentials on anti-atherosclerosis by anti-oxidative effect and suppressive effect on LDL oxidation.
