Objectives : Evodia officinalis DODE (EO), an herbal plant, has been widely used in traditional Korean medicine for the treatment of vascular diseases such as hypertension. The crude extract of EO contains phenolic compounds that are effective in protecting liver microsomes, hepatocytes, and erythrocytes against oxidative damage. But EO has been little found to have an anti-inflammatory activity. We investigated anti-inflammatory activity of EO in RAW 264.7 cells and human umbilical vein endothelial cells (HUVECs). Methods : Cytotoxic activity of EO on RAW 264.7 cells was investigated by using 5-(3-caroboxymeth-oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. The nitric oxide (NO) production was measured by Griess reagent system. And proinflammatory cytokines were measured by ELISA kit. The levels of intracellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) expression were measured by flow cytometer. Results : EO decreased LPS-induced NO production in RAW 264.7 cells. The inhibitory activity of EO on LPS-induced NO release is probably associated with suppressing TNF-${\alpha}$, IL-6 and MCP-1 formation. These results indicate that EO has potential as an anti-inflammatory agent. Moreover, EO decreased TNF-${\alpha}$-induced IL-8, IL-6 production, and ICAM-1 and VCAM-1 expression in HUVECs. Conclusions : EO inhibits TNF-${\alpha}$-induced inflammation via decreasing cytokines production and adhesion molecules expression. These results indicate that EO has potential as an anti-inflammation and anti-artherosclerosis agent.

Staphylococcal enterotoxin B (SEB) is bacterial toxin that induces the activation of immune cells. Because the inhibition of pro-inflammatory effect of SEB can resolve the inflammation, I determined the influence of functional or structural change of SEB on immune cells. The post translational modification of protein occurs through carbamylation. Carbamylation can change the structure of proteins and can modify the biological activity of protein. In the present study, I investigated the effect of carbamylated SEB (CSEB) on the inflammatory response mediated by LPS in HL-60 cells. To determine the anti-inflammatory effect of CSEB, I produced carbamylated SEB using potassium cyanate (KCN) and then examined whether CSEB involved in cytokine releases and apoptosis of LPS-stimulated HL-60 cells. Although CSEB had not any effect on the LPS-stimulated HL-60 cells, the protein levels of IL-8, TNF-${\alpha}$ and IL-$1{\beta}$ were significantly decreased by CSEB without cytotoxicity. CSEB also blocked Akt and NF-${\kappa}B$ activation. These results indicate that the suppressive effect of CSEB in LPS-stimulated cytokine releases is occurred by inhibition of Akt and NF-${\kappa}B$ activity. Through further studies, CSEB may be used as anti-inflammatory molecule that makes the immune system more efficient.

Heparin is a well-known anticoagulant widely used in various clinical settings. Interestingly, recent studies have indicated that heparin also has anti-inflammatory effects on neuroinflammation-related diseases, such as Alzheimer's disease and meningitis. However, the underlying mechanism of its actions remains unclear. In the present study, we examined the anti-inflammatory mechanism of heparin in cultured cerebral endothelial cells (CECs), and found that heparin inhibited the tumor necrosis factor $\alpha$ ($TNF{\alpha}$)-induced and nuclear factor kappa B (NF-${\kappa}B$)-dependent expression of adhesion molecules, such as intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1), which are crucial for inflammatory responses. Heparin selectively interfered with NF-${\kappa}B$ DNA-binding activity in the nucleus, which is stimulated by $TNF{\alpha}$. In addition, non-anticoagulant 2,3-O desulfated heparin (ODS) prevented NF-${\kappa}B$ activation by $TNF{\alpha}$, suggesting that the anti-inflammatory mechanism of heparin action in CECs lies in heparin's ability to inhibit the expression of cell adhesion molecules, as opposed to its anticoagulant actions.

Enzymatic oxidation of commercially available pyrogallol was efficiently transformed to an oxidative product, purpurogallin. Purpurogallin plays an important role in inhibiting glutathione S-transferase, xanthine oxidase, catechol O-methyltransferase activities and is effective in the cell protection of several cell types. However, the anti-inflammatory functions of purpurogallin are not well studied. Here, we determined the effects of purpurogallin on lipopolysaccharide (LPS)-mediated proinflammatory responses. The results showed that purpurogallin inhibited LPS-mediated barrier hyper-permeability, monocyte adhesion and migration and such inhibitory effects were significantly correlated with the inhibitory functions of purpurogallin on LPS-mediated cell adhesion molecules (vascular cell adhesion molecules, intracellular cell adhesion molecule, E-selectin). Furthermore, LPS-mediated nuclear factor-${\kappa}B$ (NF-${\kappa}B$) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) releases from HUVECs were inhibited by purpurogallin. Given these results, purpurogallin showed its anti-inflammatory activities and could be a candidate as a therapeutic agent for various systemic inflammatory diseases.

This study was conducted to investigate antioxidant activity and anti-immunological inflammatory effect of Allium victorialis subsp. platyphyllum extracts (AVPEs). Antioxidant activities of AVPEs were determined by free radical scavenging assay and reducing power test. Leaf-part extract had comparatively better antioxidant activity than other-part extracts. Antioxidant activity of extracts had protective effect for human umbilical vein endothelial cells (HUVECs) against superoxide anions secreted from activated neutrophils. Also, we observed AVPEs had inhibitory effects on the adherence of monocytic THP-1 to HUVEC monolayer to the basal level. Inhibitory effect on cell adhesion was caused by suppression of tumor necrosis factor-${\alpha}\;(TNF-{\alpha})-upregulated$ expression of vascular cellular adhesion molecule-1 (VCAM-1) and E-selectin in HUVECs. From these results, we expect to support the evidence of anti-immunological inflammatory effects of Allium victorialis subsp. platyphyllum (AVP) as a Korean traditional pharmaceutical.

In our previous study, we have shown that berberine has both anti-adipogenic and anti-inflammatory effects on 3T3-L1 adipocytes, and the anti-adipogenic effect is due to the down-regulation of adipogenic enzymes and transcription factors. Here we focused more on anti-inflammatory effect of berberine using real time RT-PCR and found it changes expressions of adipokines. We hypothesized that anti-adipogenicity of berberine mediates anti-inflammtory effect and explored leptin as a candidate mediator of this signaling. We studied this hypothesis by western blot analysis, but our results showed that berberine has no effect on the phosphorylations of STAT-3 and ERK which have important roles on leptin signaling. These results led us to conclude that the anti-inflammatory effect of berberine is not mediated by the inhibition of leptin signal transduction. Moreover, we have found that berberine down-regulates NF-${\kappa}B$ signaling, one of the inflammation-related signaling pathway, through western blot analysis. Taken together, the anti-inflammatory effect of berberine is not mediated by leptin, and berberine induces anti-inflammatory effect independent of leptin signaling.

Objective : Salvia miltiorrhiza Bunge (Labiatae) (SM), an eminent herbal plant, has been widely used in traditional Chinese medicine for the treatment of vascular diseases such as hypertension. The aim of this study was to determine whether SM inhibits production of nitrite, an index of NO, and proinflammatory cytokines in lipopolysaccharide (LPS)-treated RAW 264.7 macrophages. And this study investigated whether or not SM could reduce tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$)-induced inflammatory response in human vascular aortic smooth muscle cells (HASMC) and umbilical vein endothelial cells (HUVEC). Methods : Cytotoxic activity of SM on RAW 264.7 cells was using 5-(3-caroboxymeth-oxy phenyJ)-2H-tetra-zolium inner salt (MTS) assay. We measured the NO production using Griess Reagent System. Production of Proliflammatory cytokines was measured by Enzyme-Linked Immunosorbent Assay (ELISA). Results : Our results indicated that SM significantly inhibited the LPS-induced NO production accompanied by an attenuation of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), IL-6 and monocyte chemoattractant protein (MCP)-1 formation in macrophages. SM decreased TNF-${\alpha}$-induced IL-8, IL-6 production, and intracellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1 expression. Conclusion : These results indicate that SM has potential as an anti-inflammatory agent.

${\beta}$-sitosterol glucoside exists in a variety of plants and have anti-tumor, anti-microbial, and immunomodulatory activities. Mast cells and eosinophils play important roles in a variety of inflammatory diseases, specifically asthma and atopic dermatitis. In the present study, we used lactose-${\beta}$-sitosterol (L-BS) and investigated the effect of L-BS on inflammatory responses of the human mast cell line, HMC-1 and the human eosinophilic leukemia cell line, EoL-1. In HMC-1 cells, L-BS significantly inhibited cell migration in response to stem cell factor without cytotoxicity. However, the mRNA expression of CC chemokine receptors (CCRs), including CCR1-5, were not altered after L-BS treatment in HMC-1 cells. LPS-induced IL-4 production was also suppressed by L-BS in a dose-dependent manner. In EoL-1 cells, the concentration ranging from 0.1 ${\mu}M$ to 10 ${\mu}M$ of L-BS had no cytotoxicity and had no effect on mRNA expression of major protein-mediators derived from activated eosinophils. However, 100 ${\mu}M$ of L-BS induced the apoptosis of EoL-1 cells in a time-dependent manner. This finding indicates the possibility of L-BS as a potential therapeutic molecule in inflammatory diseases and may contribute to the need to improve current therapeutic drugs.

Allergy is an immunoglobulin E (IgE)-mediated process, and its incidence and prevalence have increased worldwide in recent years. Therapeutic agents for allergic diseases are continuously being developed, but side effects follow when used for a long-term use. Therefore, treatments based on natural products that are safe for the body are urgently required. Sword bean (Canavalia gladiata) pod (SBP) has been traditionally used to treat inflammatory diseases, but there is still no scientific basis for its anti-allergic effect. Accordingly, this study investigates the anti-allergic effect and its mechanism of SBP in vitro and in vivo. SBP reduced the nitric oxide production and decreased mRNA and protein expression of inflammatory mediates (inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2)), and inhibited the phosphorylation of nuclear factor kappa B (NF-κB), a major signaling molecule in the inflammatory response. Additionally, SBP extract treatment inhibited phosphatidylinositol-3-kinase/mammalian target of rapamycin (PI3K/mTOR) signaling activity to further inhibit degranulation and allergy mediator generation and control the balance of Th1/Th2 cells, which can induce an allergic reaction when disrupted. Furthermore, the SBP extract exhibited anti-allergic effects in anti-dinitrophenyl IgE-induced RBL-2H3 cells and ovalbumin-treated mice. These findings have potential clinical implications for the treatment as well as prevention of allergic diseases.
