  • In this study, the anti-oxidant and anti-inflammatory activities of water extract (ASSW) and 70% ethanol extract (ASSE) of Allium sativum L. stems were investigated using Raw 264.7 cells induced by lipopolysaccharide (LPS). ABTS radical scavenging activities of ASSW and ASSE at $1000{\mu}g/mL$ concentration were 96.9% and 97.8%, respectively. In order to investigate the potential anti-inflammatory effects of ASSW and ASSE, nitric oxide (NO), pro-inflammatory cytokines, interleukin-6 (IL-6), and tumor necrosis factor including ${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and prostaglandin-E2 (PGE2) were measured. ASSW and ASSE at $100{\mu}g/mL$ concentration showed inhibitory effects against NO production by 18% and 23%, respectively. Production of IL-$1{\beta}$ and IL-6 after treatment with ASSW and ASSE at $100{\mu}g/mL$ decreased by approximately 28% and 15% for ASSW and 17% and 12% for ASSE, respectively. In addition, production of TNF-${\alpha}$ after treatment of $100{\mu}g/mL$ of ASSW and ASSE decreased by 24% and 23%, respectively. In addition, the treatment of $100{\mu}g/mL$ of ASSW and ASSE showed inhibitory expressions against PGE2 by 45.47% and 33.87%, respectively. These results suggested that ASSE showed greater inhibitory activity than that of the ASSW by the suppression of inflammatory mediators, including NO, IL-6, TNF-${\alpha}$ and PGE2 production, and the expressions of iNOS and COX-2 in macrophages. In conclusion, ASSW and ASSE may have some ancillary effects on inflammatory factors as potential anti-inflammatory agents.

  • The fruit of Actinidia polygama, Mock-chun-ryo in Korea, has been used as traditional medicine for abdominal pain, rheumatic arthritis, and stroke. In a previous study, the ethanol extract of A. polygama Max. showed antiinflammatory activity in RAW 264.7 cells. In this study, we investigated the anti-inflammatory and anti-atherosclerosis effects of supercritical fluid marc extracts from A. polygama Max. Anti-inflammatory extracts were produced from supercritical fluid extraction of the silver vine under the following conditions; pressure, 1,500-4,500 psi, temperature $35-55^{\circ}C$ and extraction time 1-2 hr. To evaluate the anti-inflammatory and anti-atherosclerotic effects of the extracts, we studied nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), and tumor necrosis factor-alpha (TNF-$\alpha$) levels in RAW 264.7 cells and MMP-9 activity in human aortic smooth muscle cells (HASMC). The Marc 11 extract inhibited the production of NO, $PGE_2$, and TNF-$\alpha$ by lipopolysaccharide in RAW 264.7 cells. Moreover, the marc 11 extract inhibited TNF-$\alpha$-induced MMP-9 activity in HASMC. These results indicate that the Marc 11 extract of A. polygama Max. has the potential for use as an anti-atherosclerosis agent.

Socheongja and Socheong 2 Extracts Suppress Lipopolysaccharide-induced Inflammation and Oxidative Stress in RAW 264.7 Macrophages through Activating Nrf2/HO-1 Signaling and Suppressing MAPKs Pathway (RAW 264.7 대식세포에서 Nrf2/HO-1 신호 전달계 활성화와 MAPKs 경로 억제를 통한 소청자와 소청2호의 LPS 매개 염증성 및 산화적 스트레스 반응의 억제)

  • Inflammatory response and oxidative stress play critical roles in the development and progression of many human diseases. Therefore, a great deal of attention has been focused on finding functional materials that can control inflammation and oxidative stress simultaneously. The purpose of this study was to investigate the effects of Socheongja and Socheong 2, Korean black seed coat soybean varieties, on the inflammatory and oxidative stress induced by lipopolysaccharide (LPS) in RAW 264.7 macrophages. Our data indicated that the extracts of Socheongja (SCJ) and Socheong 2 (SC2) significantly suppressed LPS-induced production of nitrite oxide (NO) and prostaglandin $E_2$, key pro-inflammatory mediators, by suppressing the expression of inducible NO synthase and cyclooxygenase-2. It was also found that SCJ and SC2 reduced the LPS-induced secretion of pro-inflammatory cytokines, such as tumor necrosis $factor-{\alpha}$ and $interleukin-1{\beta}$, which was concomitant with a decrease in the protein levels. In addition, SCJ and SC2 markedly diminished LPS-stimulated intracellular reactive oxygen species accumulation, and effectively enhanced nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase (HO)-1 expression. Furthermore, LPS-induced activation of mitogen-activated protein kinases (MAPKs) was abrogated by SCJ and SC2. Taken together, these data suggest that SCJ and SC2 may offer protective roles against LPS-induced inflammatory and oxidative responses in RAW 264.7 macrophages through attenuating MAPKs pathway, and these effects are mediated, at least in part, through activating Nrf2/HO-1 pathway. Given these results, we propose that SCJ and SC2 have therapeutic potential in the treatment of inflammatory and oxidative disorders caused by over-activation of macrophages.

  • A study was conducted with 48 weaned barrows ($28{\pm}3d$, $8.45{\pm}0.14kg$) to determine the effect of Achyranthes bidentata polysaccharide (ABPS) supplementation on pig performance, immunological, adrenal and somatotropic responses following Escherichia coli lipopolysaccharide (LPS) challenge. The experiment was a $2{\times}2$ factorial design; the main factors included diet (supplementation with 0 or 500 mg/kg ABPS) and immunological challenge (LPS or saline). On d 14 and 21 of the trial, pigs were given an intraperitoneal injection with either $100{\mu}g/kg$ BW of LPS or an equivalent amount of sterile saline. Blood samples were obtained 3 h after injection for analysis of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), prostaglandin $E_2$ ($PGE_2$), cortisol, growth hormone (GH), insulin-like growth factor (IGF)-I and immunoglobulin G (IgG). On d 2 after LPS challenge, peripheral blood lymphocyte proliferation (PBLP) was measured. LPS administration decreased average daily feed intake (ADFI) (p<0.05), had a tendency to decrease average daily gain (ADG) (p<0.10) during both the first and second challenge periods and increased (p<0.05) feed:gain ratio only during the first challenge period. ABPS tended to improve ADG (p<0.10) during the first challenge period, and improved ADG (p<0.05) and tended to improve ADFI (p<0.10) during the second challenge period. ABPS did not affect feed:gain ratio. An interaction (p<0.05) between LPS challenge and diet was observed for the plasma concentrations of TNF-${\alpha}$, $PGE_2$ and cortisol after both LPS challenges such that, among LPS-treated pigs, pigs fed the ABPS diet were lower for these indices than those receiving the control diet. In contrast, pigs fed the ABPS diet had higher IGF-I (p<0.05) compared with those fed the control diet. No effect of diet, LPS challenge or both on GH and IgG was observed after both LPS administrations. LPS challenge increased PBLP when these cells were incubated with $8{\mu}g/ml$ of LPS during both the challenge periods, and did likewise when incubated with $8{\mu}g/ml$ of concanavalin A only after the first challenge. ABPS had no effect on PBLP. These data demonstrate that ABPS alters the release of pro-inflammatory cytokines following an immunological challenge, which might enable pigs to achieve better performance.

  • Objectives : Woogakseungmatang is a prescription medication mainly used to treat facial paralysis in Korean medicine. The purpose of this study is to investigate the effects of Woogakseungmatang on anti-inflammation and anti-oxidation. Methods : Woogakseungmatang was extracted using hot water. Cytotoxicity was assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) method; nitric oxide(NO) production and Prostaglandin $E_2$ ($PGE_2$) production in RAW cells treated with Woogakseungmatang were investigated; and the cytokine changes associated with inflammation were examined. The antioxidant capacity of Woogakseungmatang was measured using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method. Results : RAW cells treated with Woogakseungmatang showed 90% cell viability at a $100-{\mu}g/ml$ concentration. NO production was decreased by 15% at a $100-{\mu}g/ml$ concentration. $PGE_2$ production was decreased by 18% at a $100-{\mu}g/ml$ concentration. Interleukin $1{\beta}$ ($IL-1{\beta}$), interleukin 6(IL-6), and tumor necrosis factor-${\alpha}$ ($TNF-{\alpha}$) were significantly reduced at $100{\mu}g/ml$ compared with those in the control group. The DPPH free radical scavenging capability was more than 50% at $100{\mu}g/ml$. Conclusions : Woogakseungmatang showed only a slight anti - inflammatory effect at $100{\mu}g/ml$ and it was difficult to confirm the concentration-dependent anti-inflammatory effect. Therefore, this study means to confirm the potential anti-inflammatory effects of Woogakseungmatang. Based on this research, more systematic and diverse studies should be conducted.

  • Objectives : This study evaluated activities and ingredient contents concerning extracts according to extraction solvents of Insampaedok-san (IS, Renshen bai du-san). Methods : The herbal constituents of IS were extracted with water and 70% ethanol at $100^{\circ}C$ for 2 hr. Using the HPLC system, the six ingredient contents of different solvent extracts of IS were analyzed. The nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$) production and proinflammatory cytokines were measured in RAW264.7 cells stimulated with lipopolysaccharide (LPS). The macrophage-derived chemokine (MDC/CCL22) and regulated on activation normal T-cell expression and secreted (RANTES/CCL5) production were measured in HaCaT and BEAS-2B cells stimulated tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interferon-${\gamma}$ (IFN-${\gamma}$). The activities of glycerol-3-phosphate dehydrogenase (GPDH) and leptin level were measured in 3T3-L1 cells. Results : The calibration curves showed good linearity ($r^2$=1.0000) for different concentration ranges. The contents of liquiritin, naringin, hesperidin, neohesperirin and glycyrrizin in 70% ethanol extracts of IS were relatively higher than that of water extract, however the content of ferulic acid in 70% ethanol and water extract of IS were similar. The extraction solvents of water and 70% ethanol were evaluated inhibitory effect on the production of NO, $PGE_2$, TNF-${\alpha}$ and IL-6 in RAW 264.7 cells. Their extractions were inhibitory effect on production of MDC/CCL22 and RANTES/CCL5 in HaCaT cell and BEAS-2B cell, respectively. In addition, evaluated reduced on GPDH activity and leptin level in 3T3-L1 preadipocyte cell. Conclusions : Our results suggest that IS extracts were inhibitory effects of disease such as inflammation, allergies and obesity.

  • Prunus persica Flos (PPF) were investigated for their antioxidant and anti-inflammatory activities to find a natural functional food resource preventing degenerative diseases associated with excessive oxidative stress and chronic inflammation. PPF was extracted using ethanol (EtOH) and then sequentially fractioned by hexane (Hx), dichloromethane (DM), ethyl acetate (EA), n-butanol (BtOH), and water (DW). Contents of total phenolics and flavonoids, as well as 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities were measured. Anti-inflammatory effects in terms of nitric oxide (NO), prostaglandin (PG) E2, and pro-inflammatory cytokines such as interleukin (IL)-6 and tumor necrosis factor (TNF)-${\alpha}$ production were also measured using LPS-treated RAW 264.7 macrophages. EtOH extract showed relatively high antioxidant activity with high total phenolic (78.1 mg tannic acid/g) and flavonoid contents (55.3 mg rutin/g). EA fraction contained the highest total phenolic and flavonoid contents (394.6 mg tannic acid/g, 253.7 mg rutin/g), followed by BtOH (128.3 mg tannic acid/g, 93.1 mg rutin/g). EA and BtOH fractions and EtOH extract showed higher DPPH radical and ABTS radical scavenging activities than the others (P<0.05). In LPS-treated RAW 264.7 macrophages, EtOH extract ($200{\mu}g/mL$) showed significantly reduced (P<0.05) NO, PGE2, and TNF-${\alpha}$ production levels to 38.5%, 32.3%, and 48.9% of the control, respectively, as well as reduced iNOS and COX-2 protein expression. DM fraction ($50{\mu}g/mL$) showed significantly reduced (P<0.05) NO, PGE2, IL-6, and TNF-${\alpha}$ production levels to 43.5%, 13.3%, 38.7%, and 41.3% of the control, respectively, and EA fraction ($50{\mu}g/mL$) showed significantly reduced NO, PGE2, IL-6, and TNF-${\alpha}$ production levels to 44.8%, 22.4%, 45.7%, and 62.0% of the control, respectively. Taken together, EtOH extract of PPF showed potent antioxidant and anti-inflammatory activities, and EA and BtOH fractions showed comparatively stronger antioxidant activities while DM and EA fractions showed stronger anti-inflammatory activities. It can be concluded that EtOH extract of PPF and its fractions are good candidates as natural resources for the development of anti-oxidative and anti-inflammatory functional food products.

  • In order to investigate anti-inflammatory, anti-allergic and anti-obesity activities of Samchulkunbi-tang (SCT; Shen zhu jian pi-tang) water and 70% ethanol (EtOH) extracts, in vitro inhibitory activities against nitric oxide (NO), prostaglandin $E_2$ $PGE_2$), interleukin (IL)-6 and tumor necrosis factor (TNF)-${\alpha}$ production in lipopolysaccharide-stimulated RAW 264.7 cells, and macrophage-derived chemokine (MDC/CCL22) and regulated on activation of normal T-cell-expressed and -secreted (RANTES/CCL5) production in TNF-${\alpha}$/interferon-${\gamma}$-stimulated HaCaT and BEAS-2B cells as well as glycerol-3-phosphate dehydrogenase (GPDH) activity and leptin production in 3T3-L1 cells were determined. A HPLC was used for quantification of the seven marker components (albiflorin, paeoniflorin, liquiritin, naringin, hesperidin, poncirin and glycyrrhizin) of SCT water and 70% EtOH extracts. SCT showed inhibitory effects against MDC and RANTES production in HaCaT cells, as well as RANTES production in BEAS-2B cells. In addition, SCT reduced not only NO, $PGE_2$, IL-6 and TNF-${\alpha}$ production in RAW 264.7 cells, but also GPDH activity and leptin production in 3T3-L1 cells. Furthermore, the biological activities and the contents of six compounds (except paeoniflorin) were higher in 70% EtOH extract than water extract. These results suggest that SCT has anti-inflammatory, anti-allergic and anti-obesity activities. These efficacies of 70% EtOH extract are relatively higher than that of water extract.

  • Hypericum ascyron has long been used as medicinal plant and recent studies reported that H. ascyron has anti-diabetic, anti-oxidant, and anti-bacterial effects. In this study, inhibitory effect from H. ascyron on pro-inflammatory responses has been investigated. H. ascyron was extracted at optimal extraction condition. Total phenolic contents in water and 90% ethanol were 29.75 and 31.82 mg/g, respectively. Hyaluronidase inhibitory activity of H. ascyron extracts ($50-200{\mu}g/mL$ phenolics) was 0.00-14.81% and 15.33-47.49%, respectively. In cell viability, cell toxicity was shown at concentration of $100{\mu}g/mL$ and $30{\mu}g/mL$ of water and 90% ethanol extract. Therefore, $10-50{\mu}g/mL$ in water extracts and $5-20{\mu}g/mL$ in ethanol extracts was selected each for further study. Inducible nitric oxide synthase (iNOS) derived nitric oxide (NO) and cyclooxygenase (COX)-2-derived prostaglandin $E_2$ ($PGE_2$) protein expression inhibitory effect of extracts were inhibited in a dose dependent manner, significantly. Also, the pro-inflammatory cytokines inhibitory effect such as tumor necrosis $factor-{\alpha}$, nterleukin (IL)-6 and $IL-1{\beta}$ were decreased in the dose dependent manner. The results indicate that H. ascyron extracts reduced inflammatory responses in lipopolysaccharide-induced 264.7 cells via the regulation of the iNOS, COX-2, NO, $PGE_2$, and pro-inflammatory cytokines. Therefore, H. ascyron extracts have significant anti-inflammatory effect and a source as therapeutic materials.
