The objective of this study was to evaluate functionality of Mutimo cylindricus as a cosmetic ingredient, one of the brown algae. The M. cylindricus 70% ethanol extract was manufactured for antioxidant measurement. DPPH and ABTS methods were used to measure antioxidants, and its EC50 values were 2.040 and 2.182 mg/mL in each experiment. The measurement of total polyphenol contents and reducing power showed total polyphenol content of 103 mg gallic acid/g extract and reducing power of 134 mg ascorbic acid/g extract. To measure cell toxicity, MTT method was used, and its result showed that the extract was not cytotoxic. And it has anti-inflammatory and whitening activity at concentrations of 100 ㎍/mL. The result confirmed that M. cylindricus extract is available as a cosmetic material with whitening and anti-inflammatory properties.
Ginger (Zingiber officinale Roscoe) is traditionally used as appetite enhancer, improver of the digestive system, antithusive, anti-cold, antipyretic, analgesic, and antiinflammation. In vitro evaluation using human lymphocyte cultures showed almost similar indication with those in in vivo mouse study, NK cell lysing activity was improved significantly. Proliferation activity of B and T cells, and CD3$^{+}$ and CD3$^{+}$CD4$^{+}$T cell subset were better observed using oleoresin or gingerol and shogaol fractions. Although there were higher activities in gingerol, the improvement was almost equal to that by oleoresin. Shogaol did not show better improvement except at higher concentration. It could be concluded that treatment with single bioactive compound, such as gingerol, did not show significant effects compared to oleoresin, the crude extract. In human study, involving healthy male adult, the improvement of NK cell lysing activity was again demonstrated and even more apparent. The mechanism involved in the protection seemed to be through the antioxidant activity of gingerol. However, other mechanism underlying the improvement of NK cell lysing activity must be involved since this improvement seemed to be specifically toward NK cell activity. Since NK cells ave specific for the elimination of virus-infected cell and mutated cells, this positive effect on the immune system are very interesting. This work has also scientifically proved that the traditional beliefs that ginger had preventive effects on common cold appeared to be reasonable.
The quality and the nutritional ingredients and the functional activation of Nypa fruticans flower stalk was evaluated in this research. It consisted of 7.5% of water, 13.56% of crude protein, 0.84% of crude fat, 9.25% of crude ash, and 68.85% of carbohydrate. 12 kinds of minerals were identified, where the top 3 of them being K, Cl, and Na in order. There were a total of 15 types of amino acid analyzed, with the main amino acids of arginine 30.25%, aspartic acid 26.90%, and glutamic acid 17.12%. Total polyphenol content was 20,190.73 mg/100 g, and the total flavonoid content was 71.73 mg/100 g. The $IC_{50}$ for DPPH radical scavenging ability was $0.017{\pm}0.00mg/mL$ for Nypa fruticans Wurmb flower stalk, $0.672{\pm}0.01mg/mL$ for blueberry, and $1.282{\pm}0.03mg/mL$ for ginseng. The $IC_{50}$ for ABTS radical scavenging ability was $0.070{\pm}0.00mg/mL$ for Nypa fruticans Wurmb flower stalk, $2.918{\pm}0.13mg/mL$ for blueberry, and $4.131{\pm}0.24mg/mL$ for ginseng. For this reason, it is considered that containing plenty of polyphenol and antioxidant, Nypa fruticans Wurmb is related to antiinflammation. This research will contribute to production of functional foods and high value materials using Nypa fruticans Wurmb.
Background: Gastric ulcer (GU) is a common gastrointestinal disease that can be induced by many factors. Finding an effective treatment method that contains fewer side effects is important. 20 (S)-ginsenoside Rg3 is a kind of protopanaxadiol and has shown superior antiinflammatory and antioxidant effects in many studies, especially cancer studies. In this study, we examined the treatment efficacy of 20 (S)-ginsenoside Rg3 on GU. Methods: Three kinds of GU models, including an alcohol GU model, a pylorus-ligated GU model, and an acetic acid GU model, were used. Mouse endothelin-1 (ET-1) and nitric oxide (NO) levels in blood and epidermal growth factor (EGF), superoxide dismutase, and NO levels in gastric mucosa were evaluated. Hematoxylin and eosin staining of gastric mucosa and immunohistochemical staining of ET-1, inducible nitric oxide synthase (NOS2), and epidermal growth factor receptors were studied. Ulcer index (UI) scores and UI ratios were also analyzed to demonstrate the GU conditions in different groups. Furthermore, Glide XP from $Schr{\ddot{o}}dinger$ was used for molecular docking to clarify the interactions between 20 (S)-ginsenoside Rg3 and EGF and NOS2. Results: 20 (S)-ginsenoside Rg3 significantly decreased the UI scores and UI ratios in all the three GU models, and it demonstrated antiulcer effects by decreasing the ET-1 and NOS2 levels and increasing the NO, superoxide dismutase, EGF, and epidermal growth factor receptor levels. In addition, high-dose 20 (S)-ginsenoside Rg3 showed satisfactory gastric mucosa protection effects. Conclusion: 20 (S)-ginsenoside Rg3 can inhibit the formation of GU and may be a potential therapeutic agent for GU.
Background: Ginseng has a wide range of beneficial effects on health, such as the mitigation of minor and major inflammatory diseases, cancer, and cardiovascular diseases. There are abundant data regarding the health-enhancing properties of whole ginseng extracts and single ginsenosides; however, no study to date has determined the receptors that mediate the effects of ginseng extracts. In this study, for the first time, we explored whether the antiinflammatory effects of Rg3-enriched red ginseng extract (Rg3-RGE) are mediated by retinoid X receptor ${\alpha}$-peroxisome-proliferating receptor ${\gamma}$ ($RXR{\alpha}-PPAR{\gamma}$) heterodimer nuclear receptors. Methods: Nitric oxide assay, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromide assay, quantitative reverse transcription polymerase chain reaction, nuclear hormone receptor-binding assay, and molecular docking analyses were used for this study. Results: Rg3-RGE exerted antiinflammatory effects via nuclear receptor heterodimers between $RXR{\alpha}$ and $PPAR{\gamma}$ agonists and antagonists. Conclusion: These findings indicate that Rg3-RGE can be considered a potent antiinflammatory agent, and these effects are likely mediated by the nuclear receptor $RXR{\alpha}-PPAR{\gamma}$ heterodimer.

The 1,1-diphenyl-2-picrylhydrazyl free radical scavenging activity of water and ethanol extracts were 84% and 86% at $50{\mu}g/mL$phenolics, respectively. The 2,2'-Azinobis-(3-ethylbenzothiazoline-6-sulfonic acid radical decolorization activity of water and ethanol extracts were 84 and 95% at $100{\mu}g/mL$ phenolics, respectively. Antioxidant protection factor in water and ethanol extracts at $50{\mu}g/mL$ phenolics were 1.93 and 1.82 PF, respectively. Thiobarbituric acid reactive substance were 69% in water extracts and 89% in ethanol extracts at $150{\mu}g/mL$ phenolics. The inhibition activity on xanthine oxidase in water and ethanol extracts was 34 and 60%, respectively. The inhibition activity on ${\alpha}$-glucosidase was 29% in water extracts and 87% in ethanol extracts. The tyrosinase inhibitory activity was 19% in ethanol extracts. The collagenase inhibition activity of anti-wrinkle effect showed an excellent wrinkle improvement effect as 53% in water extracts and 77% in ethanol extracts at $200{\mu}g/mL$ phenolics. The hyaluronidase inhibition activity as antiinflammation effect of water extracts was confirmed to 34% of inhibition at $200{\mu}g/mL$ phenolic. The results can be expected extracts from Cornus kousa fruit to use as functional resource for antioxidant, antigout, inhibitor of carbohydrate degradation, antiwrinkle activity and antiinflammation activity.
Objectives: The purpose of this study was to investigate the effects of Chaenomelis Fructus Herba Water Extract(CF) on the production of inflammatory mediators in RAW 264.7 cell mouse macrophages stimulated with LPS. Methods: We have not examined effect of CF on the cell viability of RAW 264.7 cell until we investigated effects of CF on LPS-induced productions of NO, Ca and various cytokines in RAW 264.7 cell.

CF increased the cell viability in the RAW 264.7 cell at the density of 25, 50, 100 and 200 ${\mu}g/ml$. 2. CF inhibited significantly increasing the production of NO in LPS-induced RAW 264.7 cell at the density of 25, 50, 100 and 200 ${\mu}g/ml$. 3. CF inhibited significantly increasing the production of Intracellular Ca in LPS-induced RAW 264.7 cell at the density of 25, 50, 100 and 200 ${\mu}g/ml$. 4. CF inhibited significantly the IL-2, IL-10, IL-12p70, TNF-${\alpha}$, GM-CSF, M-CSF, LIF and VEGF of the RAW 264.7 cell induced by LPS at the density of 25, 50, 100 and 200 ${\mu}g/ml$. 5. CF inhibited significantly the IL-4 at the density of 25, 50 ${\mu}g/ml$, the IL-5, IL-15 and MIG at the density of 25, 50 and 200 ${\mu}g/ml$ and IFN-${\gamma}$ at the density of 25, 100 ${\mu}g/ml$ respectively in the RAW 264.7 cell increased by LPS. Conclusions: CF inhibited significantly increasing IL-2, IL-10, IL-12p70, TNF-${\alpha}$, GM-CSF, M-CSF, LIF, VEGF, NO and Ca in LPS-induced RAW 264.7 cell at the density of more than 25 ${\mu}g/ml$ without causing the toxicity. These results signify that CF has antiinflammatory effect on controlling the over inflammatory reaction by the RAW 264.7 cell.

Objectives The object of this study was to investigate the antioxidative and antiinflammatory effects of Jinmu-tang extract (JMT) on the Monosodium iodoacetate (MIA)-induced rat osteoarthritis. Methods To investigate the antioxidant capacities of JMT, we measured the total polyphenol and flavonoid, and 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-Azino-bis(3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity. To evaluate the antioxidative and antiinflammatory effects of JMT, the rats were divided into 5 groups (n=8). Normal group was not induced by MIA and treated at all (N), control group was induced by MIA and not treated at all (Con), positive control group was induced by MIA and orally administered indomethacin 5 mg/kg (Indo) and experimental groups were induced by MIA and orally administered JMT 100 mg/kg (JMT100) and JMT 200 mg/kg (JMT200) for 4 weeks. The changes of anti-type II collagen antibody in serum, heme oxygenase-1 (HO-1), phosphorylated inhibitor of ${\kappa}B{\alpha}$ ($p-I{\kappa}B{\alpha}$), cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS) and tumor necrosis factor alpha ($TNF-{\alpha}$) in knee joint tissue and histopathological observation (Hematoxylin & Eosin and Safranin-O stain) were measured. Results Total polyphenol and flavonoid levels of JMT were $26.90{\pm}0.33mg/g$ and $6.02{\pm}0.34mg/g$. $IC_{50}$ of L-ascorbic acid and JMT of DPPH radical scavenging activity were $1.35{\pm}0.07{\mu}g/ml$ and $52.95{\pm}0.97{\mu}g/ml$. $IC_{50}$ of L-ascorbic acid and JMT of ABTS radical scavenging activity were $3.18{\pm}0.02{\mu}g/ml$ and $91.49{\pm}1.74{\mu}g/ml$. In serum, the anti-type II collagen antibody levels of JMT100 and JMT200 groups were decreased significantly. In knee joint tissue, the HO-1 level of JMT200 was increased significantly. The $p-I{\kappa}B{\alpha}$ and $TNF-{\alpha}$ levels of JMT200 were decreased significantly. The COX-2 and iNOS levels of JMT groups were decreased significantly. In histopathological observation, in comparison with Con, synovial tissue, cartilage and proteoglycan of JMT100 and JMT200 were well preserved. Conclusions According to the results, It is considered that JMT has antioxidant and antiinflammatory effects for MIA-induced rat osteoarthritis, so it could be applied to osteoarthritis treatment.
Hyaluronidase inhibitory activity as inflammatory factor of Koreinsis chinensis leaf ethanol extract was showed higher inhibitory activity than water extract. 29.5% inhibitory activity was shown at concentration of $200{\mu}g/mL$ phenolics. Lipopolysaccharide (LPS)-stimulated Raw 264.7 cells were treated with different concentrations ($5-25{\mu}g/mL$) of Koreinsis chinensis leaf extract and the amount of nitric oxide (NO) was determined; LPS-treated cells produced 3 times more NO than non-LPS treated cells. Moreover, the NO production in cells treated with Koreinsis chinensis leaf extract showed inhibitory effect in a concentration-dependent manner. Due to the stimulant-induced NO production is regulated by the inducible nitric oxide synthase (iNOS), we determined the iNOS protein level to elucidate the mechanism by which the NO production was inhibited. It was reduced by 40% with a Koreinsis chinensis leaf extract concentration of $25{\mu}g/mL$ and identified iNOS inhibition in dose-dependent manner. The prostaglandin $E_2$ production in cells treated with Koreinsis chinensis leaf extract was reduced by 26.2% at concentration of $25{\mu}g/mL$. The protein expression of cyclooxygenase-2 in LPS-treated Raw 264.7 cells was inhibited by 64% at $25{\mu}g/mL$ of Koreinsis chinensis leaf extract. Koreinsis chinensis leaf extract had a concentration-dependent inhibitory effect on the production of tumor necrosis factor-${\alpha}$ and interleukin-6 as pro-inflammatory cytokine in LPS-treated Raw 264.7 cells at $25{\mu}g/mL$ of Koreinsis chinensis leaf extract. Their levels were decreased by 61.7 and 62% respectively.
