The anti-oxidant activities and ${\beta}$-glucan contents of wild mushrooms collected from Songnisan, Soi-myeon, Joryeongsan, and Ganghwado, Korea, were investigated. Among the wild mushroom extracts, Pycnoporus sanguineus (OK1071), Piptoporus soloniensis (OK1090), and Daedalea dickinsii (OK1094) extracts showed the highest DPPH and $ABTS^+$ radical scavenging activities. The nitrite scavenging activity and total polyphenol content of the extract of P. sanguineus (OK1071) was 74.2% and 37.7 mg GAE/g, respectively, and these values were much higher than those of the other mushrooms analyzed in this study. The Pearson's correlation coefficients of the DPPH radical and nitrite scavenging activities with the total polyphenol contents of the wild mushroom extracts were r = 0.758 (p < .01) and r = 0.951 (p < .01), respectively. The ${\beta}$-glucan contents of Lenzites betulina (OK1040), Trametes versicolor (OK1044), and P. sanguineus (OK1071) were 47.8%, 43.9%, and 41.8%, respectively, which were higher than those of the other mushrooms. Therefore, the wild mushrooms analyzed were confirmed to have excellent antioxidant activities and high ${\beta}$-glucan contents. Accordingly, the fundamental data provided in this study can be used to isolate useful compounds from these wild mushrooms.

The present study aimed to investigate the comparative evaluation of pharmacological efficacy between sulfasalazine alone and combination with herbal medicine on dextran sodium sulfate (DSS)-induced UC in mice. Balb/c mice received 5% DSS in drinking water for 7 days to induce colitis. Animals were divided into five groups (n = 9): group I-normal group, group II-DSS control group, group III-DSS + sulfasalazine (30 mg/kg), group IV-DSS + sulfasalazine (60 mg/kg), group V-DSS + sulfasalazine (30 mg/kg) + Radish Extract mixture (30 mg /kg) (SRE). DSS-treated mice developed symptoms similar to those of human UC, such as severe bloody diarrhea and weight loss. SRE supplementation, as well as sulfasalazine, suppressed colonic length and mucosal inflammatory infiltration. In addition, SRE treatment significantly reduced the expression of pro-inflammatory signaling molecules through suppression both MAPK) and nuclear factor-kappa B (NF-${\kappa}B$) signaling pathways, and prevented the apoptosis of colon. Moreover, SRE administration significantly led to the up-regulation of anti-oxidant enzyme including SOD and Catalase. This is the first report that Radish extract mixture combined with sulfasalazine protects against experimental UC via the inhibition of both inflammation and apoptosis, very similar to the standard-of-care sulfasalazin.

Phytochemical compounds of Ligusticum striatum Makino are used as traditional medicinal herbs in Asia. These compounds are reported to have pain relief and antioxidant activities in gynecological and brain diseases. In this study, we investigated the antioxidant effects of Ligusticum fermented ethanol extract from Lactobacillus plantarum BHN-LAB 129 isolated from Kimchi, a Korean traditional food. The total polyphenol and total flavonoid contents increased by about 116.2% and 281.0% respectively, in the fermented Ligusticum extract as compared with those in the nonfermented Ligusticum ethanol extract. Superoxide dismutase-like (SOD), DPPH radical scavenging, ABTS radical scavenging, and reducing power activities increased by around 139.9%, 199.6%, 301.0%, and 137.1%, respectively, in the fermented Ligusticum ethanol extract as compared with these parameters in the nonfermented Ligusticum ethanol extract, respectively. In conclusion, the fermented Ligusticum ethanol extract with L. plantarum BHN-LAB 129 was effective in increasing the antioxidant effects. The bioconversion process in this study points to the potential of using Ligusticum to produce phytochemical-enriched natural antioxidant agents with high added value. The findings may prove useful in the development of improved foods and cosmetic materials.
Morphology of cumulus-oocyte-complexes (COCs) at germinal vesicle (GV) stage as one of the evaluation criteria for oocyte maturation quality after in vitro maturation (IVM) plays important roles on the meiotic maturation, fertilization and early embryonic development in pigs. When cumulus cells of COCs are insufficient, which is induced the low oocyte maturation rate by the increasing of reactive oxygen species (ROS) in porcine oocyte during IVM. The ROS are known to generate including superoxide and hydrogen peroxide from electron transport system of mitochondria during oocyte maturation in pigs. To regulate the ROS production, the cumulus cells is secreted the various antioxidant enzymes during IVM of porcine oocyte. Our previous study showed that Mito-TEMPO, superoxide specific scavenger, improves the embryonic developmental competence and blastocyst formation rate by regulating of mitochondria functions in pigs. However, the effects of Mito-TEMPO as a superoxide scavenger to help the anti-oxidant functions from cumulus cells of COCs on meiotic maturation during porcine oocyte IVM has not been reported. Here, we categorized experimental groups into two groups (Grade 1: G1; high cumulus cells and Grade 2: G2; low cumulus cells) by using hemocytometer. The meiotic maturation rate from G2 was significantly (p < 0.05) decreased (G1: $79.9{\pm}3.8%$ vs G2: $57.5{\pm}4.6%$) compared to G1. To investigate the production of mitochondria derived superoxide, we used the mitochondrial superoxide dye, Mito-SOX. Red fluorescence of Mito-SOX detected superoxide was significantly (p < 0.05) increased in COCs of G2 compared with G1. And, we examined expression levels of genes associated with mitochondrial antioxidant such as SOD1, SOD2 and PRDX3 using a RT-PCR in porcine COCs at 44 h of IVM. The mRNA levels of three antioxidant enzymes expression in COCs from G2 were significantly (p < 0.05) lower than COCs of G1. In addition, we investigated the anti-oxidative effects of Mito-TEMPO on meiotic maturation of porcine oocyte from G1 and G2. Meiotic maturation and mRNA levels of antioxidant enzymes were significantly (p < 0.05) recovered in G2 by Mito-TEMPO ($0.1{\mu}M$, MT) treatment (G2: $68.4{\pm}3.2%$ vs G2 + MT: $73.9{\pm}1.4%$). Therefore, our results suggest that reduction of mitochondria derived superoxide by Mito-TEMPO may improves the meiotic maturation in IVM of porcine oocyte.

Rosemary (Rosmarinus officinalis L.) is widely used as a food material. Although various physiological activities of rosemary have been reported, there have been no studies on the physiological activity of solvent extracts with different polarities. Rosemary extracts were obtained by extraction of dried powder using 0%, 25%, 50%, 70%, and 95% ethanol (EtOH) in distilled water, methanol, ethyl acetate, and hexane. As these ratios of EtOH are generally chosen by default and scarcely optimized, we investigated the impact of the composition of EtOH in distilled water on extract-related characteristics, such as DPPH free radical scavenging and ${\alpha}$-glucosidase inhibition, on the differentiation of 3T3-L1 adipocytes and inhibition of tyrosinase. Adipogenesis inhibition was highest at 70% EtOH. DPPH scavenging activity and inhibition of tyrosinase activity were reduced with 50% EtOH in water. However, inhibition of ${\alpha}$-glucosidase activity was higher in 50% EtOH in water. The best solvents in terms of DPPH scavenging activity, inhibition of tyrosinase and ${\alpha}$-glucosidase, and differentiation of adipocytes obtained with different concentrations of EtOH, although a lower similar activities were found with 50% ethanol. Considering the extraction solvents, a ratio of EtOH in water gives different content and constituents of compounds. These differences will give activities inhibition of adipogenesis, tyrosinase, ${\alpha}$-glucosidase activity, and DPPH scavenging activity.
Background: Glycyrrhiza radix (licorice root) have been used as an oriental medicine material for long time, and its protective effects on oxidative stress, inflammation and cognition deficit have been recently reported. However, the cultivation of Glycyrrhiza species as medicinal crops is associated with some problems such as low productivity and early leaf fall, etc. To resolve this problems, Glycyrrhiza cultivars have been developed by direct hybridization of each Glycyrrhiza species by Korean researchers. The present study was conducted to compare the Glycyrrhiza cultivar radix (Dagam, Sinwongam and Wongam) for their anti-oxidation, anti-inflammation, and cognition improvement effects and levels of liquiritin, isoliquiritigenin and licochalcone in order to select an excellent cultivar as a material resource. Methods and Results: For evaluating the inhibitory efficacies of the Glycyrrhiza cultivar extracts on oxidative stress and inflammation in BV2 cells, we measured their reactive oxygen species (ROS) production and nitric oxide (NO) release after treating them with lipopolysccharide. The scavenging activities on 2,2-diphenyl-1-picrylhydrazyl (DPPH) and peroxynitrite ($NOO^-$) radicals were evaluated. Cell proliferation and N-methyl-D-aspartate receptor (NMDAR) inhibition were analyzed. The total phenol, liquiritin, isoliquiritigenin and licochalcone A content in the extracts of the three culivars were quantified. Furthermore, the correlation coefficient between the activities and contents of total phenol, liquiritin, isoliquiritigenin and licochalcone A were also calculated. The results indicated that Sinwongam exhibited potent anti-oxidant, anti-inflammatory and NMDAR inhibititory activities. Sinwongam also showed higher total phenol and licochalcone A contents than the other cultivars. Among the three cultivars, Dagam exhibited a positive effects on NO release inhibition, cell proliferation and contents of liquiritin and isoliquiritigenin. Conclusions: Sinwongam is expected to be the most useful resource as a functional material for anti-oxidation/anti-inflammation and cognition improvement among the three studied licorice cultivars.

POGO is a dynamic axial instability phenomenon that occurs in liquid-propelled rockets. As the natural frequencies of the fuselage and those of the propellant supply system become closer, the entire system will become unstable. To predict POGO, the propellant (oxidant and fuel) tank in the first stage is modeled as a shell element, and the remaining components, the engine and the upper part, are modeled as mass-spring, and structural analysis is performed. The transmission line model is used to predict the pressure and flow perturbation of the propellant supply system. In this paper, the closed-loop transfer function is constructed by integrating the fuselage structure and fluid modeling as described above. The pogo suppressor consists of a branch pipe and an accumulator that absorbs pressure fluctuations in a passive manner and is located in the middle of the propellant supply system. The design parameters for its design optimization to suppress the decay phenomenon are set as the diameter, length of the branch pipe, and accumulator. Multiple-objective function optimization is performed by setting the energy minimization of the closed loop transfer function in terms of to the mass of the pogo suppressor and that of the propellant as the objective function.

Objective: This study investigated the effects of the administration of ethanolic saffron petal extract (SPE) and vitamin E (Vit E) on growth performance, blood metabolites and anti-oxidant status in Baluchi lambs. Methods: Thirty-two Baluchi male lambs ($35.22{\pm}5.75kg$) were randomly divided into 4 groups. The 1st (control), 2nd (injectable saffron petal extract [ISPE]), and 3rd (Vit E) groups were respectively injected subcutaneously with either physiological saline (5 mL), SPE (25 mg/kg body weight [BW]) or DL-${\alpha}$-tocopheryl acetate (225 IU) once a week. An oral dose of SPE (500 mg/kg BW) was also administered to the 4th group (oral saffron petal extract [OSPE]). Feed intake and BW were measured for 42 days and blood samples were taken on days 1, 14, 28, and 42. The lambs were slaughtered, and tissue samples were taken. Results: Growth performance and many blood metabolites were not affected (p>0.05) by the treatments. Cholesterol of plasma in the ISPE and Vit E groups was similar and less (p<0.01) than both the OSPE and control groups. Although there was no significant difference between the control and other groups for plasma triglyceride, the ISPE group showed lower (p<0.05) triglyceride than the OSPE and Vit E groups. The highest (p<0.01) plasma glutathione peroxidase (GPx) was detected in the OSPE group, while the ISPE and Vit E groups showed higher (p<0.01) superoxide dismutase (SOD) of plasma than the control. Malondialdehyde of plasma in the ISPE group was lower (p<0.05) than the OSPE. No differences (p>0.05) were observed among the groups for antioxidant status of both longissimus dorsi muscle and liver. However, the activity of GPx in the kidney and heart, as well as SOD activity in the kidney, were influenced ($p{\leq}0.01$) by the treatments. Conclusion: Adding ethanolic SPE improved antioxidant status and lowered lipids oxidation in lambs. The SPE and Vit E demonstrated similar effects on antioxidant status in lambs.
Atractylodes macrocephala is a perennial herb and is a member of the Compositae family. This plant is known to contain various bioactive constituents indicating anti-inflammatory, neuroprotective, anti-oxidant, immunological enhancement, and gastroprotective effects. In this investigation, we isolated four compounds with similar chemical structures from A. macrocephala, and evaluated their anti-inflammatory effects. Among the four compounds, compound 2(atractylenolide II) showed the second-best inhibitory effect on the lipopolysaccharide(LPS)-induced production of nitric oxide in RAW264.7 macrophages and BV2 microglial cells. Compound 2 also inhibited the LPS-induced the production of prostaglandin E2(PGE2), and the expression of inducible nitric oxide synthase(iNOS) and cyclooxygenase(COX)-2 proteins in both cells. In addition, compound 2 suppressed the production of pro-inflammatory cytokines including interleukin(IL)-1β, IL-6, and tumor necrosis factor(TNF)-α. These inhibitory effects were contributed by inactivation of nuclear factor kappa B(NF-κB) and mitogen-activated protein kinases(MAPKs) pathways by treatment with compound 2. This compound did not induce the expression of heme oxygenase(HO)-1 protein indicating that the anti-inflammatory effect of compound 2 was independent with HO-1 protein. Taken together, these results suggested that atractylenolide II can be a candidate material to treat inflammatory diseases.

Oryeong-san (ORS) is a traditional Korean herbal medicine widely used for renal associated diseases, composed of five medicine herbs; Atractylodes japonica Koidzumi, Cinnamomum cassia Presl, Polyporus umbellatus Fries, Poria cocos Wolf and Alisma orientale Juzepzuk. We studied to improve the convenience of intake and portability by developing modernized dosage forms, and examined the effect on anti-inflammation of ORS. In order to develop the tablet formulation of ORS (ORS-F), the tablets were evaluated on the basis of physical characteristics include diameter, thickness, weight variation, hardness, friability and disintegration. To analyze the marker components of ORS-F, eight index markers from five herbal medicines were chosen. And the method using high performance liquid chromatography (HPLC) with diode-array detector method was established for the simultaneous analysis. The biological activities were examined the effect of ORS-F on pro-inflammation mediated by LPS-stimulation. The production of nitric oxide (NO) and cytokines were determined by reacting cultured medium with griess reagent and enzyme-linked immunosorbent assay (ELISA). The expression of cyclooxygenase-2 (COX-2) and inducible NO synthase (iNOS) were investigated by Western blot and RT-PCR. The anti-oxidant activities of OJS-F increased markedly, in a dose-dependent manner. and, The total phenolic compound and flavonoids contents of OJS-F were 10.20±0.09 ㎍/㎎ and 12.86±0.86 ㎍/㎎. OJS-F which is LPS has diminished in the LPS-induced release of inflammatory mediators (NO, iNOS, COX2 and PGE2) and pro-inflammatory cytokines (TNF-α, IL-6 and IL-1β) from the RAW264.7 macrophages. Therefore, the developed formulation for tablet of ORS-F provide efficiency and usability, and indicated effect of anti-inflammation.
