The aim of the present study is to investigate the anti-inflammatory effect of a vegetable soup (VS). The present study was designed to determine the effect of the vegetable soup on pro-inflammatory factors such as NO, iNOS and TNF-$\alpha$ in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The cell toxicity was determined by MTS assay. To evaluate the anti-inflammatory effect of vegetable soup, amount of NO was measured using the NO detection kit and the iNOS expression was measured by reverse transcriptase polymerase chain reaction (RT-PCR). Also, proinflammatory cytokines were measured by ELISA kit. The results showed that the vegetable soup reduced NO, iNOS and TNF-$\alpha$ production without cytotoxicity. Our results suggest that the vegetable soup may have an anti-inflammatory property through suppressing inflammatory mediator productions and appears to be useful to develop the functional food realted to anti-inflammation.

Background: Bladder cancer is among the five most common malignancies worldwide. Altered expression of suppressor of cytokine signaling -3 (SOCS-3) has been implicated in various types of human cancers; however, its role in bladder cancer is not well established. Aim: The present study was undertaken to investigate the mRNA expression of SOCS-3 in normal and cancerous bladder tissue and to explore its correlation with urinary levels of some proinflammatory cytokines, cytokeratin-18 (CK -18) and with tumor histopathological grading, in order to evaluate their role as potential diagnostic markers. Materials and Methods: SOCS3 mRNA expression levels were evaluated using quantitative real time PCR. Urinary levels of interleukins 6 and 8 were estimated by enzyme linked immunosorbent assay (ELISA). Cytokeratin-18 expression was analyzed by immuunohistochemistry then validated by ELISA. Results: SOC3 m RNA expression levels were significantly lower in high grade urothelial carcinoma ($0.36{\pm}0.12$) compared to low grade carcinoma ($1.22{\pm}0.38$) and controls ($4.08{\pm}0.88$), (p<0.001). However, in high grade urothelial carcinoma the urinary levels of IL-6, IL-8, total CK-18($221.33{\pm}22.84pg/ml$, $325.2{\pm}53.6pg/ml$, $466.7{\pm}57.40U/L$ respectively) were significantly higher than their levels in low grade carcinoma ($58.6{\pm}18.6pg/ml$, $58.3{\pm}50.2pg/ml$, $185.5{\pm}60.3U/L$ respectively) and controls ($50.9{\pm}23.0pg/ml$, $7.12{\pm}2.74pg/ml$, $106.7{\pm}47.3U/L$ respectively), (p<0.001). Conclusions: Advanced grade of urothelial bladder carcinoma is significantly associated with lowered mRNA expression of SOC3 as well as elevated urinary levels of proinflammatory cytokines and CK-18. Furthermore, our results suggested that urinary IL-8, IL-6 and CK-18 may benefit as noninvasive biomarkers for early detection as well as histopathological subtyping of urothelial carcinoma.

Objective: The effects of vaccinating 18-day-old chicken embryos with the combination of recombinant Eimeria profilin plus Clostridium perfringens (C. perfringens) NetB proteins mixed in the Montanide IMS adjuvant on the chicken immune response to necrotic enteritis (NE) were investigated using an Eimeria maxima (E. maxima)/C. perfringens co-infection NE disease model that we previously developed. Methods: Eighteen-day-old broiler embryos were injected with $100{\mu}L$ of phosphate-buffered saline, profilin, profilin plus necrotic enteritis B-like (NetB), profilin plus NetB/Montanide adjuvant (IMS 106), and profilin plus Net-B/Montanide adjuvant (IMS 101). After post-hatch birds were challenged with our NE experimental disease model, body weights, intestinal lesions, serum antibody levels to NetB, and proinflammatory cytokine and chemokine mRNA levels in intestinal intraepithelial lymphocytes were measured. Results: Chickens in ovo vaccinated with recombinant profilin plus NetB proteins/IMS106 and recombinant profilin plus NetB proteins/IMS101 showed significantly increased body weight gains and reduced gut damages compared with the profilin-only group, respectively. Greater antibody response to NetB toxin were observed in the profilin plus NetB/IMS 106, and profilin plus NetB/IMS 101 groups compared with the other three vaccine/adjuvant groups. Finally, diminished levels of transcripts encoding for proinflammatory cytokines such as lipopolysaccharide-induced tumor necrosis $factor-{\alpha}$ factor, tumor necrosis factor superfamily 15, and interleukin-8 were observed in the intestinal lymphocytes of chickens in ovo injected with profilin plus NetB toxin in combination with IMS 106, and profilin plus NetB toxin in combination with IMS 101 compared with profilin protein alone bird. Conclusion: These results suggest that the Montanide IMS adjuvants potentiate host immunity to experimentally-induced avian NE when administered in ovo in conjunction with the profilin and NetB proteins, and may reduce disease pathology by attenuating the expression of proinflammatory cytokines and chemokines implicated in disease pathogenesis.

Chan-Su (Venenum bufonis) has long been for a variety of other purposes including treatment of inflammation in the folk medicine recipe. Since nitric oxide (NO) is one of the major inflammatory parameters, we first studied the effects of Chan-Su on NO production in lipopolysaccharide (LPS)-stimulated BV2 microglial cells, Chan-Su inhibited the secretion of NO in BV2 microglial cells, without affecting cell viability, The protein level of inducible nitric oxide synthase (iNOS) was decreased by Chan-Su, And Chan-Su also inhibited production of prostaglandin E2 (PGE2) and expression of cyclooxygenase (COX)-2. Proinflammatory cytokines, such as tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$ and IL-12, were inhibited by Chan-Su in a dose-dependent manner. And Chan-Su inhibited the degradation of ${IkB-\alpha}$, which was considered to be inhibitor of nuclear factor $(NF)-{\kappa}B$, one of a potential transcription factor for the expression of iNOS, COX-2 and proinflammatory cytokines. These results suggest that Chan-Su could exert its anti-inflammatory actions by suppressing the synthesis of NO through inhibition of $I{\kappa}B-{\alpha}$ degradation.

Purpose: Solar ultraviolet (UV) radiation causes inflammation and matrix metalloproteinase (MMP) overexpression and extracellular matrix depletion, leading to skin photoaging such as wrinkle formation, dryness, and sagging. Activation of MMP is influenced by various molecules such as reactive oxygen species (ROS), proinflammatory cytokines, and transient receptor potential vanilloid type (TRPV)-1, which are increased in UV-irradiated skin cells. Aralia elata (AE) ethanolic extract was reported to inhibit ROS generation caused by UVB-irradiation in keratinocytes. In this study, we investigated the photoprotective effect of AE ethanolic extract on UVB-irradiated human keratinocytes (HaCaT) and human dermal fibroblasts (HDF). Methods: AE was freeze-dried, extracted in 70% ethanol, and concentrated. Skin cells were treated with AE extract for 24 h and then exposed to UVB ($55mJ/cm^2$). After 48 h of incubation, proinflammatory cytokines, MMP-1, type-1 procollagen, and TRPV-1 levels were measured by ELISA or Western blotting. Results: Treatment with AE extract ($100{\mu}g/mL$) significantly inhibited UVB-induced IL-6, IL-8, and $PGE_2$ production in HaCaT by 25.6%, 5.3%, and 70.2%, respectively, and also inhibited elevation of MMP-1 and TRPV-1 caused by UVB irradiation by 20.0% and 41.9%, respectively (p < 0.05). In HDF, AE extract treatment significantly inhibited both elevation of MMP-1 and reduction of type-1 procollagen caused by UVB irradiation (p < 0.05). In addition, type-1 procollagen was elevated by AE extract treatment in normal HDFs (p < 0.05). Conclusion: AE 70% ethanol extract has photoprotective ability via reduction of proinflammatory mediators, TRPV-1 and MMP-1 production, and elevation of collagen synthesis. Our findings suggest that AE extract might be a good natural material to protect against UVB-induced premature skin aging.

The intestinal tight junction (TJ) plays an important role as a paracellular barrier. Impaired TJ permeability and enhanced proinflammatory cytokine production are crucial pathophysiological mechanisms in inflammatory bowel diseases (IBDs). Although proinflammatory cytokines, tumor necrosis factor-alpha and interluekin-1 beta, which are markedly increased in IBD patients, have been reported to increase intestinal TJ permeability, the role of interleukin-1 alpha (IL-1α) in the TJ has not been studied. Phytochemicals could prevent proinflammatory cytokine-caused TJ alteration. Curcumin (CCM), a biologically active component of turmeric, has a strong anti-inflammatory activity. The purpose of this study was to elucidate the effect of IL-1α on intestinal epithelial TJ permeability and the role of CCM in IL-1α′s action on TJ in an in vitro intestinal epithelial system, Caco-2 monolayers. The TJ integrity of Caco-2 monolayers was estimated by measuring the flux of FITC-labeled dextran and transepithelial electrical resistance (TEER). Apical IL-1α (100 ng/ml) treatment elevated TJ permeability and suppressed TEER of Caco-2 monolayers. Pretreatment with CCM (20 μM) for 30 min significantly inhibited IL-1α-induced TJ alterations, such as increased TJ permeability and decreased in TEER values. These results demonstrated that IL-1α-induced increases in Caco-2 TJ permeability and CCM blocked the action of IL-1α in the TJ.

The purpose of this study was to investigate the effects of Violae Herba Water Extract (VH) on the proinflammatory factors of lipopolysaccharide (LPS)-induced on the production of inflammatory mediators in RAW 264.7 mouse macrophages cells. We examined effect of Violae Herba Water Extract on the cell viability of RAW 264.7 mouse macrophages cells. Futhermore, After 24 hours treatment we investigated anti-inflammatory effect of Violae Herba Water Extract by the production of Bio-Plex cytokine assay, concentrations of various cytokines such NO, $interleukin(IL)-1{\beta}$, tumor necrosis factor ${\alpha}(TNF-{\alpha})$ and IL-6. The water extract of Violae Herba significantly inhibited the production of NO, $IL-1{\beta}$, $TNF-{\alpha}$ and IL-6 at the concentration of 25, 50, 100 and $200{\mu}g/mL$ in the LPS-induced RAW 264.7 mouse macrophages cells with no changes in the cell viability of them. These results suggest that water extract of Violae Herba has anti-inflammatory effect related with its inhibition of proinflammatory cytokines such as $IL-1{\beta}$, $TNF-{\alpha}$ and IL-6 in the LPS-induced RAW 264.7 mouse macrophages cells. Further research is needed to develop therapeutic agents for inflammatory diseases using Violae Herba.

Excessive or chronic inflammation contributes to the pathogenesis of many inflammatory diseases such as sepsis, rheumatoid arthritis, and ulcerative colitis. Hibiscus syriacus L. has been used as a medicinal plant in many Asian countries, even though its anti-inflammatory activity has been unclear. Therefore, we investigated the anti-inflammatory effect of anthocyanin fractions from the H. syriacus L. varieties Pulsae (PS) on the lipopolysaccharide (LPS)-induced expression of proinflammatory mediators and cytokines in RAW264.7 macrophages. PS suppressed LPS-induced nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) secretion concomitant with downregulation of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2) expression. Furthermore, PS inhibited the production of proinflammatory cytokines such as tumor necrosis factor-alpha ($TNF-{\alpha}$), interleukin-6 (IL-6), and IL-12 in LPS-stimulated RAW264.7 macrophages. Further study showed that PS significantly decreased LPS-induced nuclear translocation of the nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) subunits, p65 and p50. Molecular docking data showed that many anthocyanins from PS fit into the hydrophobic pocket of MD2 and bound to Toll-like receptor 4 (TLR4), indicating that PS inhibits the TLR4-MD2-mediated inflammatory signaling pathway. Especially, apigenin-7-O-glucoside most powerfully bound to MD2 and TLR4 through LYS122, LYS122, and SER127 at a distance of $2.205{\AA}$, $3.098{\AA}$, and $2.844{\AA}$ and SER441 at a distance of $2.873{\AA}$ (docking score: -8.4) through hydrogen bonding, respectively. Additionally, PS inhibited LPS-induced TLR4 dimerization/expression on the cell surface, which consequently decreased MyD88 recruitment and IRAK4 phosphorylation. PS completely blocked LPS-mediated mortality in zebrafish larvae by diminishing the recruitment of neutrophil and macrophages accompanied by low levels of proinflammatory cytokines. Taken together, our results indicate that PS attenuates LPS-mediated inflammation in both in vitro and in vivo by blocking the TLR4/MD2-MyD88/IRAK4-$NF-{\kappa}B$ axis. Therefore, PS might be used as a novel modulatory candidate for effective treatment of LPS-mediated inflammatory diseases.
