The purpose of this study was to investigate the role of the Moringa oleifera (M. oleifera) extract as a cosmetic additive. The tyrosinase and elastase inhibitory effects showed 47% and 39% at $1,000{\mu}g/mL$ concentration, respectively. Also, the collagenase inhibition effect was 31% at $500{\mu}g/mL$ concentration. A cell viability test, measured on macrophage cell (RAW 264.7) and melanoma cell (B16F10) by ethanol extract of M. oleifera, showed 94.2% and 94.8% at $100{\mu}g/mL$ concentration, respectively. In order to confirm anti-inflammatory activity, we examined the inhibitory effects on the production of lipopolysaccharides (LPS)-induced NO in RAW 264.7 cells by Griess assay. As a result, the M. oleifera extract showed a concentration-dependent inhibition of NO production. The protein expression inhibitory effects of M. oleifera extract were measured by western blot at 25, 50, $100{\mu}g/mL$ concentration and the ${\beta}-actin$. Results showed that the expression inhibition rates of the iNOS, COX-2, MITF, TRP-1, TRP-2, tyrosinase protein were decreased by 85.8%, 57.5%, 80.7%, 30%, 29.9%, 23.6% at $100{\mu}g/mL$ concentration, respectively. It was concluded that M. oleifera extracts had the anti-inflammatory and whitening effects and thus could be applied for cosmetics as a natural ingredient.

This study was designed to investigate the beneficial effects of fermented Rhus verniciflua stem bark extract (RVSBE) on the stomach. We evaluated RVSBE for its antimicrobial activity against Helicobacter pylori (H. pylori), along with its ability to reduce the viability of human gastric cancer AGS cells. In addition, its anti-inflammatory effect was examined by evaluating nitric oxide (NO) production, and inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 mRNA expression in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. RVSBE showed antimicrobial activity, as 2.0 mg of the extract produced a clear inhibition zone of 4.0 mm. RVSBE inhibited the growth of AGS cells by 20% at concentrations ranging from 0.25-1.0 mg/mL. Regarding the anti-inflammatory effects of RVSBE, at 0.1-1.0 mg/mL, the extract showed more than 75% inhibition of NO production. In addition, cells treated with 0.25 mg/mL RVSBE showed a 25% decrease in iNOS mRNA levels compared to those in the LPS-treated cells. These results suggest that RVSBE may have significant inhibitory effects on inflammatory mediators, and therefore, may be a potential anti-inflammatory candidate.

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.

To investigate the biological benefits of Korean traditional vegetables, anti-oxidative and anti-inflammatory effects of ethanol extracts from blanched and dried sprouts of evening primrose (Oenothera laciniata, OL) and gooseberry (Actinidia arguta, AA) were measured. Total polyphenol and flavonoid contents of OL were higher than those of AA; OL contained 60.4 mg tannic acid/g dry weight and 31.9 mg rutin/g dry weight, while AA contained 33.0 mg tannic acid/g dry weight and 20.3 mg rutin/g dry weight. The $IC_{50}$ value for DPPH radical scavenging activity was $58.2{\mu}g/mL$ for OL ethanol extract and $122.1{\mu}g/mL$ for AA ethanol extract. The reducing power upon $500{\mu}g/mL$ of ethanol extract treatment was as strong as $52.1{\mu}g$ ascorbate eq./mL for OL and $45.3{\mu}g$ ascorbate eq./mL for AA. Regarding anti-inflammatory effects, inhibition rate against 5-lipoxygenase (LOX) and cyclooxygenase (COX)-2 activities were 29.5% and 79.5% for OL, as well as 11.5% and 39.1% for AA, respectively at a concentration of $250{\mu}g/mL$. Lipopolysaccaride ($1{\mu}g/mL$)-treated RAW 264.7 macrophage cells subjected to OL ethanol extract at various concentrations ($0{\sim}25{\mu}g/mL$) showed significantly reduced synthesis of nitrite oxide (NO), prostaglandin (PG) E2, and IL-6 in a dose-dependent manner without cytotoxicity, although TNF-${\alpha}$ synthesis was not affected. In conclusion, both OL and AA sprouts showed strong antioxidative activity, whereas OL showed very strong anti-inflammatory activity via effective reduction of NO, PGE2, and IL-6 synthesis in LPS-activated macrophage cells.

Yeonguemjiri-tang(連芩止痢湯, YGT) exhibits potent anti-inflammatory activity in widely intestine disease, but its mechanism undisclosed. To elucidate the molecular mechanisms of YGT on pharmacological and biochemical actions in inflammation, we examined the effect of YGT on pro-inflammatory mediators in phorbol 12-myristate 13-acetate (PMA) plus A23187-induced mast cell and lipopolysaccharide (LPS)-stimulated macrophages. The investigation focused on whether YGT inhibited pro-inflammatory cytokines such as interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in PMA plus A23187-induced HMC-1 cells and inflammatory madiators such as nitric oxide (NO), TNF-${\alpha}$, IL-6, iNOS, COX-2 in LPS-stimulated RAW 264.7 cells. We found that YGT inhibited LPS-induced NO, TNF-${\alpha}$ and IL-6 productions as well as the expressions of iNOS and COX-2. These results suggest that YGT has inhibitory effects on mast cell-mediated and macrophage-mediated inflammation.

Purpose: This study was conducted to identify the effects of a lifestyle intervention program on weight gain, dietary habits, fatigue and pregnancy stress, blood pressure, and neonatal birth weight, using Cox's interaction model of client health behavior for overweight and obese women. Methods: This was a quasi-experimental research with a non-equivalent control group pre-post test design. A total of 52 patients who met the selection criteria, including 25 in the experimental group and 27 in the control group, were the subjects of the study; they comprised overweight and obese pregnant women who were receiving prenatal care at A and B women's hospital in J province. The lifestyle intervention program ran for 12 weeks in total and consisted of interactions involving affective support, health information, and professional/technical competencies. The data collection period was from February 1, 2017 to August 31, 2017. Results: This study showed differences in the appropriate weight gain rate (χ²=6.17, p=.013), suppression of an increase in fatigue (t=-2.32, p=.012), and an increase in pregnancy stress (t=-1.87, p=.034). Yet, no differences in physical activity, dietary habits change, blood pressure, and neonatal birth weight (p>.05) were found. Conclusion: The study findings indicate that this program could be an effective intervention for the control of appropriate weight gain, fatigue, and pregnancy stress. Therefore, a lifestyle intervention program based on Cox's interaction model of client health behavior could be an efficient strategy for a positive health outcome of overweight and obesity pregnant women.

Objectives : Scutellaria barbata has been widely used in oriental medicine used for treatment of acute and chronic inflammatory diseases. In this study, to investigate the protective effect of Scutellaria barbata on type I allergic response, we determined whether Scutellaria barbata inhibits early or late allergic responses. Methods : To assess the effect of Scutellaria barbata Pharmacopuncture Extract(SB) in RBL-2H3 cells, we investigated the levels of the markers of degranulation such as ${\beta}$-hexosaminidase and histamine, inflammatory mediator such as IL-4, TNF-${\alpha}$, PGE2 and cysLT, and mRNA expression of cytokines and enzymes. In addition, we determined the levels of intracellular ROS by DCFH-DA assay and the free radical scavenging activity by DPPH method. Results : We found that SB suppressed the release of ${\beta}$-hexosaminidase and histamine and the production of IL-4, TNF-${\alpha}$, PGE2 and cysLT in RBL-2H3 by the antigen stimulation. SB also significantly inhibited the enzyme mRNA expressions, such as HDC2, COX-1, COX-2, 5-LOX and iNOS2, along with reduced cytokine mRNA expressions, such as IL-$1{\beta}$, IL-2, IL-3, IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ and GM-CSF in RBL-2H3. In addition, SB suppressed the levels of intracellular ROS. Conclusions : Our results indicate that SB protects against type I allergic response and exert an anti-inflammatory effect through the inhibition of degranulation, inflammatory mediator release and mRNA expression of cytokines and enzymes.

Soy, high dietary intake for the oriental population, is a main source of isoflavonoids. Sophoricoside (SOP) an isoflavone glycoside was isolated from immature fruits of Sophora japonica (Leguminosae family) and its inhibitory effect on chemical mediators involved in inflammatory response was investigated in this study. SOP inhibited the interleukin (IL)-6 bioactivity with an $IC_{50}$ value of 6.1 $\mu$M whereas it had no effects on IL-1$\beta$ and TNF-a bioactivities. SOP was identified as a selective inhibitor of cyclooxygenase (COX)-2 activity with an $IC_{50}$ value of 4.4 $\mu$ M, but did not show inhibitory effect on the synthesis of COX-2. However, SOP had no effect on the production of reactive oxygen species including superoxide anions and nitric oxide. These results revealed that in vitro anti-inflammatory action of SOP is significantly different from that of genistein known as a phytoestrogen of soy products. This experimental study has documented an importance of dietary soy isoflavonoids as multifunctional agents beneficial to human health, and will help to clarify protective mechanisms of SOP against inflammatory conditions.

Inflammation plays an important role in host defense against external stimuli such as infection by pathogen, endotoxin or chemical exposure by the production of the inflammatory mediators that produced by macrophage. Anti-inflammatory factor is important to treat the dangers of chronic inflammation associated with chronic disease. This research aims to analyze the anti-inflammatory effects of Garcinia mangostana L. peel extract (GMPE), ${\alpha}$-mangostin, and ${\gamma}$-mangostin in LPS-induced murine macrophage cell line (RAW 264.7) by inhibiting the production of inflammatory mediators. The cytotoxic assay of G. mangostana L. extract, ${\alpha}$-mangostin, and ${\gamma}$-mangostin were performed by MTS (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) to determine the safe and non-toxic concentration in RAW 264.7 for the further assay. The concentration of inflammatory mediators (COX-2, IL-6, and IL-$1{\beta}$) were measured by the ELISA-based assay and NO by the nitrate/nitrite colorimetric assay in treated LPS-induced RAW 264.7 cells. The inhibitory activity was determined by the reducing concentration of inflammatory mediators in treated LPS-induced RAW 264.7 over the untreated cells. This research revealed that GMPE, ${\alpha}$-mangostin, and ${\gamma}$-mangostin possess the anti-inflammatory effect by reducing COX-2, IL-6, IL-$1{\beta}$, and NO production in LPS-induces RAW 264.7 cells.
