In this study, we investigated the anti-inflammatory effects of fermented Hizikia fusiformis extracts in lipopolysaccharide (LPS)-stimulated RAW 264.7 mouse macrophages. The fermentation was performed using Lactobacillus casei in mixture of carbon source at $30^{\circ}C$ for 30 days. The sample groups were prepared with/without L. casei group in order to demonstrate the anti-inflammatory activity of fermented H. fusiformis in regard to lactic acid bacteria. As a result, we confirmed the inhibitory effect of H. fusiformis extracts on LPS-stimulated NO production and expression of $TNF{\alpha}$, while it had no regulatory effect on the expression of iNOS, COX-2, $IL-1{\beta}$ and IL-6 as important inflammatory factors. However, L. casei fermented group significantly suppressed the expression of the above factors. In particular, the difference between the two groups in the matter of mRNA expression of iNOS, which is directly associated with NO production, indicated that the fermentation with lactic acid bacteria effectively suppressed NO production by regulating iNOS expression. Also, effective suppression of pro-inflammatory cytokines showed that the fermentation using L. casei may provide an increment towards extraction of active ingredients that are effective anti-inflammatory agents.

Objectives : DojukSan is known to be effective for treating a urinary diseases and stomatitis. However, there has been a lack of studies regarding the effects of Dojuksan on the inflammatory activities and effector inflammatory disease mechanism about macrophage before is not known. To elucidate the molecular mechanisms of Dojuksan water extract (DJS) on pharmacological and biochemical actions in inflammation, we examined the effect of DJS on pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated macrophages. Methods : In the present study, pro-inflammatory cytokine production was determined by performing enzyme-linked immunosorbent assay, reverse transcription polymerase chain reaction, and western blot analysis to measure the activation of MAPKs. Cells were treated with 200 ng/mL of LPS 1 h prior to the addition of DJS. Cell viability was measured by MTS assay. The investigation focused on whether DJS inhibited nitric oxide (NO) and prostaglandin E2 ($PGE_2$) productions, as well as the expressions of inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-6 (IL-6) and mitogen-activated protein kinases (MAPKs) in LPS-stimulated RAW 264.7 cells. Results : We found that DJS inhibited LPS-induced NO, $PGE_2$ and IL-6 productions as well as the expressions of iNOS and COX-2. Furthermore, DJS suppressed the LPS-induced phosphorylation of p38 MAPK and c-Jun NH2-protein kinase (JNK). Conclusions : These results suggest that DJS has inhibitory effects on LPS-induced $PGE_2$, NO, and IL-6 production, as well as the expressions of iNOS and COX-2 in the murine macrophage. These inhibitory effects occur through blockades on the MAPKs phosphorylation.

Multiple beneficial properties of Opuntia ficus indica (OPF) are well established. In the present study, we have investigated the immunological role of OPF extract (OPFE) on murine splenocytes. OPFE dose- and time-dependently enhanced the proliferation of splenocytes without cytotoxicity. Our results also showed that the number of $CD4^+$ helper T cells and CD45R/$B220^+$ pan B cells increased markedly, but not $CD8^+$ cytotoxic T cells or $CD11b^+$ granulocytes/macrophages. In addition, OPFE significantly decreased the production levels of T helper (Th) 1 type cytokines, interferon (IFN)-$\gamma$, and tumor necrosis factor (TNF)-$\alpha$, although had no significantly differences in those of interleukin (IL)-4, a Th2 type cytokine in concanavalin A (Con A)-stimulated blastogenic cells. Furthermore, OPFE alone strongly increased IL-4 production and decreased TNF-$\alpha$ production even in the absence of Con A. On the basis of these results, this study suggests that OPFE enhances immunity by regulating the pro- and anti-inflammatory response, indicating that this extract exerts a marked immunomodulatory effect, confirming its usefulness as therapy for immune-related diseases.

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. And when p-value is below 0.05, it is judged to have the significant difference statistically(P<0.05). Results: 1. 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.

In order to investigate the possibility of Kamisamultang(KMSMT) as therapeutic for the treatment of atopic dermatitis(AD), cytotoxicity, anti-oxidant activity, modulatory and suppression activities of KMSMT were tested. 90% or higher cell viability was observed in all tested groups from 25 to 200 ${\mu}g/m{\ell}$ using Raw 264.7 cells. KMSMT showed dose-dependent DPPH scavenging activity, with more than 80% scavenging activities at 400 and 800 ${\mu}g/m{\ell}$ concentrations. KMSMT showed dose-dependent suppression activity of reactive oxygen species(ROS) production, especially at 200 ${\mu}g/m{\ell}$ of 42.6%. KMSMT decreased nitric oxide(NO) production activity dose dependently, expecially at 200 ${\mu}g/m{\ell}$ of 30.9%. IL-$1{\beta}$, IL-6, MCP-1, TNF-${\alpha}$ production rate were decreased by 45.7%, 15.5%, 8.9%, 16.5% respectively when Raw 264.7 cells were treated with LPS and with KMSMT of 200 ${\mu}g/m{\ell}$. However, only IL-$1{\beta}$ and MCP-1 showed significant changes. The results above strongly suggest the modulatory and suppressive effect of KMSMT. The results above indicate that KMSMT significantly reduces the effect of oxidative and inflammatory cytokines. The use of KMSMT in atopic dermatitis can be widely suggested.

Codium fragile (CF) is an edible green alga consumed as a traditional food source in Korea. In this study, the ethanol extract of CF was evaluated to determine if it has anti-inflammatory activity. Lipopolysaccharide (LPS), a toxin from bacteria, is a potent inducer of inflammatory cytokines, such as tumor necrosis factor (TNF)-$\alpha$ and interleukin (IL)-6. Therefore, we studied whether CF extracts have an anti-inflammatory effect in LPS-induced murine macrophage cell lines (RAW 264.7). In the present study, IL-6 production was measured using an enzyme-linked immunosorbent assay (ELISA), prostaglandin $E_2$($PGE_2$) production was measured using the EIA kit, and cyclooxygenase (COX)-2 and mitogen-activated protein kinase (MAPK) activation were determined by Western blot analysis. IL-6 mRNA, COX-2 mRNA and iNOS mRNA expression were measured using reverse transcription-polymerase chain reaction (RT-PCR). The results indicated that CF extracts inhibit LPS-induced IL-6, NO and PGE2 production in a dose-dependent manner, as well as expression of iNOS and COX-2. CF extracts significantly inhibited LPS-induced c-Jun N-terminal kinase (JNK) 1/2 phosphorylation. Taken together, these findings may help elucidate the mechanism by which CF modulates RAW 264.7 cell activation under inflammatory conditions.

Salicornia herbacea L. (Chenopodiaceae: S. herbacea) is a salt marsh plant, which has long been prescribed in traditional medicines for the treatment of intestinal ailments, nephropathy, and hepatitis in Oriental countries. In order to elucidate the mechanisms of this herb, we conducted an anti-oxidative activity, the inhibition of nitric oxide (NO) production, and the suppression of the pro-inflammatory cytokine genes, with the solvent-extracts of S. herbacea. We found that both ethyl acetate and n-butanol tractions showed potent anti-oxidative effects in comparison to other fractions using xanthine oxidase assay with $IC_{50}$ values of $66.0{\pm}0.5\;{\mu}g/ml$ and $82.5{\pm}3.8\;{\mu}g/ml$, respectively. In addition, both ethyl acetate and n-butanol fractions showed more electron donating activity (EDA) than other tractions, according to DPPH (2, 2-Diphenyl-lpicrylhydrazyl radical) assay. The EDA of ethyl acetate fraction ($IC_{50}$ values of $117.5{\pm}3.8\;{\mu}g/ml$) is more significant than that of n-butanol fraction ($IC_{50}$ values of $375.0{\pm}12.5\;{\mu}g/ml$). Among potential anti-oxidative tractions, ethyl acetate traction dose-dependently suppressed lipopolysaccharide (LPS, $0.1\;{\mu}g/ml$)-induced nitric oxide (NO) production in RAW264.7 cell, while n-butanol did not. As expected, ethyl acetate fraction suppressed the expression of inducible NO synthase (iNOS) in RAW264.7 cell stimulated by $0.1\;{\mu}g/ml$ of LPS. Moreover, the ethyl acetate traction suppressed the expression of interleukin-1 $(IL)-1{\beta}$ and granulocyte/macrophage colony-stimulating factor (GM-CSF) mRNA in LPS-stimulated RAW264.7 cells. Therefore, these results suggest that S. herbacea may have anti-oxidative and anti-inflammatory activities by modulating radical-induced toxicity and various pro-inflammatory responses.
