  • In the present study, the anti-inflammatory effect of Haepyoeiin-tang plus Antler water extract water extract was tested in Xylene-Application mouse ear acute inflammation model. The test articles were once dosed before Xylene-Application, and the changes on Dody weight and weights and histopathological observation of induced ear were conducted with ear histomorphometry, The increases of absolute and relative ear weight detected in vehicle control compared to that of sham, were significantly and dose-dependently inhibited by Haepyoejin-tang plus Antler in the present study, A classic acute inflammatory histological changes such as subcutaneous edema, hypertrophy and infiltration of inflammatory cells, was detected in vehicle control. However, these histological changes were significantly and dose-dependently inhibited by Haepyoeiin-tang plus Antler. In addition, the increases of ear thickness half and thickness full detected in the vehicle control, were also dose-dependently decreased in the all Haepyoeiin-tang plus Antler-dosing groups. Base on these results, it is concluded that Haepyoeiin-tang plus Antler water extracts have a clear anti-inflammatory effect on the acute inflammation. However, somewhat lower anti-inflammatory effects were detected in Haepyoeiin-tang plus Antler water extracts compare to that of Dethamethason and Dicrofenac. About 500 mg/kg of Haepyoeiin-tang plus Antler water extracts have similar effect compared to that of Dicrofenac 15 mg/kg.

  • In the present study, the halophyte C. falcatum extract and its solvent fractions (n-hexane, 85% aqueous methanol, n-butanol, and water) were evaluated for antioxidant and anti-inflammatory activities. Antioxidative ability was measured by DPPH radical, intracellular reactive oxygen species (ROS) and peroxynitrite scavenging, DNA oxidation inhibition, and ferric reducing antioxidant power (FRAP). For DPPH radical and peroxynitrite scavenging, DNA oxidation inhibition, and FRAP, 85% aq.MeOH and n-BuOH fractions showed significant scavenging activity. For production of intracellular ROS in HT-1080 cells, 85% aq.MeOH fraction showed the highest scavenging activity. In addition, anti-inflammatory activity was also assessed by measuring the inhibitory effect against mRNA expression of pro-inflammatory factors (NO, IL-1β, IL-6 and COX-2) in LPS-stimulated Raw 264.7 macrophages. For NO production, crude extract exhibited a strong inhibitory effect at a concentration of 100 ㎍/ml. For mRNA expression of pro-inflammatory cytokines (IL-1β, IL-6, and COX-2), n-BuOH greatly suppressed expression levels of IL-1β and IL-6 at 100 ㎍/ml concentration while 85% aq. MeOH fraction significantly inhibited that of COX-2 even at 100 ㎍/ml. These results suggest that C. falcatum may be used as a potential source for the development of a natural antioxidant or anti-inflammatory agent.

  • Marine brown seaweeds are a source of functional ingredients with various biological properties. They have been used in the food and functional food industries. Brown seaweeds are divided into three parts of blades, stipe, and root. Normally seaweed blades were used as raw materials for biological research. However, there are limited uses on stipes of Ecklonia maxima (E. maxima) depending on the physicochemical, nutritional, and biological properties. Besides, the comparative studies of two structures of E. maxima, blades and stipe didn't discover previously. This study aimed to compare the potent antioxidant and anti-inflammatory activities of the two structures of E. maxima, blades and stipe in vitro studies to increase the utilization of the two structures of E. maxima. The enzyme-assisted hydrolysate from E. maxima showed significant antioxidant and anti-inflammatory activities. Among them, celluclast-assisted hydrolysate from E. maxima blades (EMBC) and viscozyme-assisted hydrolysate from E. maxima stipe (EMSV) expressed significant protection on hydrogen peroxide-induced oxidative stress. Moreover, EMBC and EMSV treatment remarkably reduced nitric oxide production by downregulation of pro-inflammatory cytokine expressions in lipopolysaccharide-stimulated Raw 264.7 cells. Especially EMBC showed strong inhibition on pro-inflammatory cytokine production compared to EMSV. Taken together research findings suggest that EMBC and EMSV possessed potent antioxidant and anti-inflammatory properties and may be utilized as functional ingredients in the food and functional food sectors.

  • In this study, we tested the anti-inflammatory effects of broccoli leaf hexane fraction to confirm the applicability as a functional material in food and cosmetics. This sample was extracted using 70% ethanol from Broccoli leaf and then fractionated with hexane. The production of pro-inflammatory cytokines (TNF-α, IL-4, IL-6, IL-1β), protein expression of iNOS and COX-2, phosphorylation of MAPKs (ERK, JNK, p38) and NF-κB with broccoli leaf hexane fraction were assayed on LPS-stimulated RAW264.7 cells. The broccoli leaf hexane fraction inhibited the secretion of pro-inflammatory cytokines and protein expression of iNOS and COX-2. Also, the broccoli leaf hexane fraction reduced the phosphorylation of MAPKs and NF-κB. Therefore, it is considered that th broccoli leaf hexane fraction has the potential to be used as a natural anti-inflammatory material in food and cosmetics. In the future, it is considered necessary to study the anti-inflammatory mechanism and identification of major bioactive substances.

  • Chrysanthemum coronarium L. contains various antioxidants such as beta-carotene, vitamins A and C, and polyphenols, and is known to have anti-inflammatory effects. Under the assumption that the PDRN contained in the extract can mediate the anti-inflammatory response, the mouse macrophages, RAW264.7 cells, were stimulated with LPS to induce the conversion to inflammatory cells, and then the addition of PDRN extracted from the extract was effective in inhibiting inflammation. It was analyzed whether there was The gene expression of IL-1β and TNF-α was used as an anti-inflammatory index, and the relative expression levels of each gene were confirmed by RT-PCR. As a result, RT-PCR confirmed the effect of PDRN-induced inhibition of inflammation in both IL-1β and TNF-α genes. Therefore, based on this study, it is considered to be a precedent data that can be developed as a treatment for inflammatory diseases, and it will be helpful in research and development of a treatment that can improve the anti-inflammatory mechanism.

  • Background: Sulforaphane (SFN) is an isothiocyanate compound present in cruciferous vegetables. Although the anti-inflammatory effects of SFN have been reported, the precise mechanism related to the inflammatory genes is poorly understood. Objectives: This study examined the relationship between the anti-inflammatory effects of SFN and the differential gene expression pattern in SFN treated ob/ob mice. Methods: Nitric oxide (NO) level was measured using a Griess assay. The inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression levels were analyzed by Western blot analysis. Pro-inflammatory cytokines (tumor necrosis factor [TNF]-α, interleukin [IL]-1β, and IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). RNA sequencing analysis was performed to evaluate the differential gene expression in the liver of ob/ob mice. Results: The SFN treatment significantly attenuated the iNOS and COX-2 expression levels and inhibited NO, TNF-α, IL-1β, and IL-6 production in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. RNA sequencing analysis showed that the expression levels of 28 genes related to inflammation were up-regulated (> 2-fold), and six genes were down-regulated (< 0.6-fold) in the control ob/ob mice compared to normal mice. In contrast, the gene expression levels were restored to the normal level by SFN. The protein-protein interaction (PPI) network showed that chemokine ligand (Cxcl14, Ccl1, Ccl3, Ccl4, Ccl17) and chemokine receptor (Ccr3, Cxcr1, Ccr10) were located in close proximity and formed a "functional cluster" in the middle of the network. Conclusions: The overall results suggest that SFN has a potent anti-inflammatory effect by normalizing the expression levels of the genes related to inflammation that were perturbed in ob/ob mice.

  • Objectives : Allium Hookeri (AH) is a traditional herb to treat inflammatory diseases in India and Myanmar. Recently, AH cultivation was succeeded in South Korea. This study was performed to evaluate the anti-inflammatory effects of Korean AH in RAW264.7 cells, mouse macrophage cell line. Methods : To evaluate the anti-inflammatory effects of root of AH, we prepared the 70% ethanol extract, then we examined the productions of nitrite, and pro-inflammatory cytokines. To examine the nitrite, and cytokines, the RAW264.7 cells were treated with AH, then stimulated with lipopolysaccharide (LPS, 500 ng/ml) for 24 h. Then the cells were harvested for griess assay, ELISA and real-time reverse transcription polymerase chain reaction (RT-PCR). Also to detect the ability of AH to induce heme oxygenase-1 (HO-1), we examined the HO-1 expression using real time RT-PCR and western blot. Furthermore, we examined the mitogen activated-protein kinases (MAPKs) and nuclear factor kappa B (NF-${\kappa}B$) activation to find out the underlying mechanisms. Results : AH ethanol extract significantly inhibited the productions of nitrite and interleukin (IL)-$1{\beta}$. AH treatment increased the HO-1 expression dramatically at 1 h, then peaked at 3 h. When the HO-1 was inhibited by tin (Sn) protoporphryin-IX (SnPP), the anti-inflammatory action of AH was reversed. AH treatment inhibited the activation of p38, but not extracelluar signal-regulated kinase (ERK 1/2) and c-Jun $NH_2$-terminal kinase (JNK) and also the degradation of inhibitory kappa B a (Ik-$B{\alpha}$) in the LPS-stimulated RAW 264.7 cells. Conclusions : These data could suggest that AH exerts anti-inflammatory influences through up-regulation of HO-1 and deactivation of p38.

  • Objectives : Hemorrhoids are one of the most common diseases in humans. Jingyoganghwaltang (JG) and Cheongsimhwan (CS) have been used for treating hemorrhoids in Korean traditional clinical practice. The present study was designed to evaluate the traditional effects of JG and CS on the experimental hemorrhoid model in rats. Methods : Hemorrhoids are closely related to inflammation. Accordingly, we examined the nitric oxide (NO) production in macrophage cell line in order to evaluate the anti-inflammatory effect. The expression levels of inflammation related genes including IL-1 beta, IL-6, INOS, and TNF-alpha were examined via a real-time quantitative PCR. Croton oil-induced hemorrhagic animal model was used to test the in vivo efficacy against hemorrhoids. The rectal tissues were weighed and the inflammatory proteins were measured to confirm the anti-inflammatory effects. Results : JG and CS have a statistically significant effect on inhibition of NO production and on the reduction of inflammatory gene expression such as IL-1 beta, IL-6, INOS, and TNF-alpha. The synergistic effects of co-treatment of JG and CS were found out in the IL-6 gene expression. The in vivo study using croton oil-induced hemorrhoid model in rat was performed to check the co-treatment effects. As a result, the co-treatment reduced the inflammation of the rectal tissue and decrease the inflammation related protein productions including ICAM1, MMP2 and MMP9. Conclusions : These results suggest that JG and CS co-treatment demonstrated anti-inflammatory effects in croton oil-induced hemorrhoid model in rat.

  • Objectives : To develop natural ingredients that help prevent or treat anti-inflammatory-related diseases and use themas basic data, we investigated anti-inflammatory activity of Cynanchi Atrati Radix Et Rhizoma water extracts(CWE) in lipopolysaccharide(LPS)-induced murine macrophage cell line, RAW 264.7 cells. Methods : The cell viabilities were evaluated with RAW 264.7 cells. The production of nitric oxide(NO), prostaglandin E2(PGE2), pro-inflammatory cytokines such tumor necrotic factor(TNF)-α and interleukin(IL)-6 were assessed in LPS-induced RAW 264.7 cell treated with CWE. Furthermore, the protein expression of inducible nitric oxide synthase (iNOS), cyclooxygenase-2(COX-2), and mitogen-activated protein kinase(MAPK) were assessed by western blotting. Results : In RAW 264.7 cell, the cell viability by CWE treatment was more than 98.4% at a concentration of 100-400 ㎍/mL. At a concentration of 800 ug/ml of CWE, the cell viability was as low as 86%. At doses of 100, 200 and 400 ㎍/mL, CWE inhibited the production of NO, PGE2, TNF-𝛼 and IL-6 in a dose-dependent manner and also decreased the expression of iNOS and COX-2 from LPS-induced RAW 264.7 cells. In addition, CWE significantly inhibited the MAPK pathway including decreased the phosphorylation of the p38, c-Jun N-terminal kinase(JNK) and extracellular signal-regulated kinase(ERK1/2). Conclusions : Our study provides evidence that CWE inhibits the production of main pro-inflammatory molecules in LPS-induced RAW 264.7 cells via expression of p38, JNK, and ERK1/2 MAPK signaling pathways. Therefore, CWE is expected to be widely used as a natural ingredient for anti-inflammatory functional foods or pharmaceuticals in the future.

  • Purpose: This study was performed to evaluate the anti-inflammatory effect of Manbunbang extract (MBB). Methods: In order to understand the mechanism of anti-inflammatory effect of MBB, expression of cytokines and its levels in RAW 264.7 cell lines, as well as changes of cytokine gene expressions in serum, spleen, and liver tissues in acute inflammation induced mouse model were investigated. Results: 1. MBB significantly suppressed the expression levels of IL-1${\beta}$, TNF-${\alpha}$ and COX-2 mRNAs at 100 and 50 ${\mu}$g/m${\ell}$ concentrations, and IL-6 and NOS-II genes at 100, 50 and 10 ${\mu}$g/m${\ell}$ concentrations in RAW 264.7 cell lines, compared to those of the control. 2. MBB significantly reduced the production level of IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ at 100 and 50 ${\mu}$g/m${\ell}$ concentrations in RAW 264.7 cell lines compared the those of the control. 3. MBB significantly reduced the production of IL-1${\beta}$, IL-6 and TNF-${\alpha}$ levels in sera of acute inflammation induced mice. 4. MBB significanlty suppressed the expression level of IL-1${\beta}$, TNF-${\alpha}$ mRNA in spleen tissues as well as IL-6 mRNA in liver tissues in acute inflammation induced mice. Conclusion: From the results above, anti-inflammatory effect of MBB through its immune regulation could be experimentally explained. Wide treatment of inflammatory diseases such as pelvic inflammation using MBB are recommended.
