Objectives : We determined the anti-inflammatory activity of KCNS-001 that is a herbal formula including 6 medicinal plants and that are used to mitigate atopic dermatitis in oriental medicine. Methods : To evaluate anti-inflammatory effect of KCNS-001, we measured the production of reactive oxygen species (ROS), nitric oxide (NO) and cyclooxygenase-2 (COX-2) in LPS-activated Raw 264.7 cells. Cell viability was determined by MTT assay. The concentrations of ROS and relative level of NO were measured with DPPH assay and Griess reagent, respectively. COX-2 and TNF-$\alpha$ were detected by enzyme immuno assay (EIA) and enzyme-linked immunosorbent assay (ELISA). Results : ROS and NO production were reduced by KCNS-001 in a dose-dependent manner. KCNS-001 significantly inhibited activity of COX-2 and suppressed the release of tumor necrosis factor-alpha (TNF-$\alpha$). Conclusions : These results indicate that the KCNS-001 may have an anti-inflammatory agent for the treatment of various inflammatory disease.

Objectives: This study aims to investigate the anti-inflammatory effect and improvement of dyslipidemia on Hyangsapyeongwi-san. Methods: In this study, HUVEC cells were cultured and treated with Hyangsapyeongwi-san to measure intracellular KLF2, eNOS, MCP-1, ICAM-1, and VCAM-1 gene expression levels related to anti-inflammation. The weight of experimental animals administered with Hyangsapyeongwi-san was measured, blood samples were biochemically analyzed, and liver tissues were reviewed to research histological changes. Results: Gene expression levels in the cells treated with Hyangsapyeongwi-san generally showed a meaningful anti-inflammatory effect. The body weight of the experimental animals decreased, and total cholesterol, triglyceride, and LDL-cholesterol in the blood generally declined while HDL-cholesterol tended to increase. Fat accumulation between hepatocytes was also reduced after the administration of Hyangsapyeongwi-san. Conclusions: This study confirmed that Hyangsapyeongwi-san has the effect of suppressing vascular inflammatory responses through the regulation of genes involved in the vascular inflammatory process and improving dyslipidemia through the reduction of blood lipids and weight loss.

In this study, to evaluate the anti-oxidative and anti-inflammatory effects of Carpinus pubescens Burkill ethanol extract (CPEE), we performed the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, reactive oxygen species (ROS) inhibition, and nitric oxide (NO) scavenging assays and an analysis of the related protein expressions. CPEE showed high DPPH radical scavenging activity and effectively increased ROS inhibition activity dose-dependently. Furthermore, CPEE induced the expression of the anti-oxidative enzyme heme oxygenase 1 and its upstream transcription factor, nuclear factor-E2-related factor 2, in RAW 264.7 cells. CPEE was associated with a reduction in NO production, which was induced by lipopolysaccharide treatment in a dose-dependent manner. The expression of inducible nitric oxide synthase (iNOS), an upstream regulator of NO production, was also inhibited. Taken together, these results suggest that CPEE has anti-oxidative and anti-inflammatory activities and could be useful as a potential anti-oxidant and antiinflammatory agent.

In this study, we analyzed the anti-oxidative and anti-inflammatory activities of seven medicinal herbs. All extracts of the tested herbs, Euryale ferox Salisbury, Echinops setifer Iljin, Amomum cardamomum Linne, Tetrapanax papyriferus, Illicium verum Hook. f., Typha orientalis Presl, and Piper longum Linne, exhibited potent anti-oxidative activity as confirmed by DPPH radical scavenging capacity. Lipopolysaccharide (LPS) induced nitric oxide (NO) production, in the RAW 264.7 cell line, was also ameliorated by all extracts' treatments in a dose dependent manner. NO suppressive activity originated from the inhibition of inducible nitric oxide synthase (iNOS) protein expression by the extracts. Three extracts, E. ferox S., I. verum Hook. f., and P. longum L., possessed suppressive activity against, not only iNOS, but also cycloxygenase 2 (COX-2) protein expression. These three extracts may then serve as potential candidates for non steroidal analgesic inflammation drugs (NSAIDs). Furthermore, all extracts induced anti-oxidative enzyme, heme oxygenase 1, protein expression. Taken together, these results provide an important new insight into the fact that various medicinal herbs possess potent anti-oxidative and anti-inflammatory activities and might be utilized as promising agents in the field of health products. Further studies for the identification of the active compounds from medicinal herbs are clearly needed.

In this study, we investigate anti-allergic and anti-inflammatory effects of Leonurus sibiricus seed (LSS) extract in basophilic leukemia RBL-2H3 cells. To identify anti-allergic actions of LSS, the degranulation was evaluated in IgE and DNP-BSA stimulated RBL-2H3 cells. At the concentration of $100{\mu}g/ml$ of methanol (MeOH) extract and Methylene chloride (MC) and Ethyl acetate (EtOAc) fractions, the degranulation was significantly inhibited 16.7%, 16.7% and 27.9% respectively. And then, to assess anti-inflammatory effects of LSS, IL-4 and IL-13 mRNA level were detected in PMA/ionomycin (PI)-induced RBL-2H3 cells and cell proliferation and IL-4 mRNA level in isolated splenocytes from Balb/c mice. LSS MeOH extract and MC and EtOAc fractions significantly decreased the level of IL-4 and IL-13 mRNA in PI-induced RBL-2H3 cells and showed inhibitory effects on cell proliferation and expression of IL-4 mRNA level in mouse splenocytes. Taken together, these results suggest that LSS has potential anti-allergic and anti-inflammatory effects and EtOAc fraction is the most effective in regulating immune responses.

Coriandrum sativum L., an annual herbaceous plant of Apiaceae family. The present study evaluated the anti-oxidant activities and anti-inflammatory effects of ethanol extracts of C. sativum. The anti-oxidant activities of C. sativum were measured by total contents of polyphenol, flavonoid, DPPH and ABTS radical scavenging and reducing power activity. And anti-inflammatory effects of C. sativum were measured by LPS-induced RAW 264.7 cells. The results showed that the contents of total polyphenol and flavonoid were 76.03 ± 1.36 mg of gallic acid equivalents/g and 182.23 ± 4.32 mg of rutin equivalents/g at concentration 1 mg/mL of C. sativum. The DPPH radical scavenging activity was found to be 52.8% at 500 ㎍/mL. The ABTS radical scavenging activity was shown in 58.3% after exposure to 1,000 ㎍/mL. Reducing power activity was found to be 66.8% at 2,000 ㎍/mL. The inhibitory effect of NO production was found to be 65% concentration 500 ㎍/mL. In the generation quantity of inflammatory cytokines such as TNF-α and IL-1β in cell culture medium, the expression levels of inflammatory proteins in cells were showed decrease with the increase of concentration. Therefore, we suggest that the C. sativum should be a potential source of alternative anti-inflammatory drug with good anti-inflammatory effects.

Background: The purpose of this study was to investigate the anti-oral microbial activity and anti-inflammatory effects of rosmarinic acid (RA) in lipopolysaccharide (LPS)-stimulated MC3T3-E1 osteoblastic cells on a titanium (Ti) surface during osseointegration, and to confirm the possibility of using RA as a safe natural substance for the control of peri-implantitis (PI) in Ti-based dental implants. Methods: A disk diffusion test was conducted to confirm the antimicrobial activity of RA against oral microorganisms. In order to confirm the anti-inflammatory effects of RA, inflammatory conditions were induced with 100 ng/ml of LPS in MC3T3-E1 osteoblastic cells on the Ti surface treated with or without 14 ㎍/ml of RA. The production of nitric oxide (NO) and prostaglandin E2 (PGE2) in LPS-stimulated MC3T3-E1 osteoblastic cells on the Ti surface was confirmed using an NO assay kit and PGE2 enzyme-linked immunosorbent assay kit. Reverse transcription polymerase chain reaction and western blot analysis were performed to confirm the expression of interleukin (IL)-1β and tumor necrosis factor (TNF)-α in total RNA and protein. Results: RA showed weak antimicrobial effects against Streptococcus mutans and Escherichia coli, but no antimicrobial activity against the bacteria Aggregatibacter actinomycetemcomitans and the fungus Candida albicans. RA reduced the production of pro-inflammatory mediators, NO and PGE2, and proinflammatory cytokines, TNF-α and IL-1β, in LPS-stimulated MC3T3-E1 osteoblastic cells on the Ti surface at the protein and mRNA levels. Conclusion: RA not only has anti-oral microbial activity, but also anti-inflammatory effects in LPS-stimulated MC3T3-E1 osteoblasts on the Ti surface, therefore, it can be used as a safe functional substance derived from plants for the prevention and control of PI for successful Ti-based implants.

Objectives : This study was conducted to investigate candidate materials as anti-inflammatory agent from extracts of Korean medicinal plants in Hwaak mountain. Ligustrum obtusifolium (LO) is a Korea medicinal plants that commonly used for robustness and hemostasis. It has been reported that LO has exhibited anti-ischemic, anti-oxidative, anti-hypolipidemic, anti-tumor and hypoglycemic effects. However, LO has not been previously reported to have an anti-inflammatory effect. Therefore, we have evaluated the anti-inflammatory effects of LO and its underlying molecular mechanisms in LPS-induced RAW 264.7 macrophages. Methods : Cell viability was determined by MTT assay in RAW 264.7 macrophages. Nitric Oxide (NO) was measured with Griess reagent and pro-inflammatory cytokines were detected by ELISA in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Protein expressions of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and p65 subunit of nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) were determined by Western blot analysis. Results : Among 15 extracts of Korean medicinal plants tested, Ligustrum obtusifolium (LO) showed the inhibition of NO production without cytotoxicity. LO reduced the expression levels of iNOS and COX-2 proteins in LPS-simulated RAW 264.7 macrophages in dose-dependent manner. Consistent with these data, LO inhibited the productions of $TNF-{\alpha}$, IL-6, and $IL-1{\beta}$ in LPS-simulated RAW 264.7 macrophages. Furthermore, LO attenuated the LPS-induced nuclear translocation of p65 $NF-{\kappa}B$ in RAW 264.7 macrophages involving suppression of $NF-{\kappa}B$ activation. Conclusions : Taken together, these results suggest that the anti-inflammatory effects of LO is associated with regulation of inflammatory mediators via inhibition of $NF-{\kappa}B$ activation in LPS-treated RAW 264.7 macrophages.
