  • Red rose petals are usually disposed but they are an abundant source of phenolics and traditionally used as food supplement and as herbal medicine. Of the Various phenolics, they are known to have anticancer, antioxidant, and anti-inflammatory properties. In this study, we investigated the anti-inflammatory effects of red rose ethanolic extracts (GRP) on lipopolysaccharide (LPS)-activated RAW 264.7 cells. The results demonstrated that pretreatment of GRP (500㎍/mL) significantly reduced NO production by suppressing iNOS protein expression in LPS-stimulated cells. Anti-inflammatory effects by red rose petals were observed in the following. Red rose petals inhibited the translocation of NF-κB from the cytosol to the nucleus via the suppression of IκB-α phosphorylation and also inhibited LPS-stimulated NF-κB transcriptional activity. These findings suggest that red rose petals exert anti-inflammatory actions and help to elucidate the mechanisms underlying the potential therapeutic values of red rose petals. Therefore, red rose petals could be regarded as a potential source of natural anti-inflammatory agents.

  • The extract of Platycodi radix has long been used as an anti-inflammatory traditional medicine in Korea for the treatment of bronchitis, asthma and acute respiratory disease. In this study, the anti-inflammatory actions of the methanol extract of Platycodi radix administered via oral administration were evaluated. The results revealed that the extracts exhibited potent anti-inflammatory action. Of the hexane, chloroform, ethyl acetate, butanol and water fractions, the butanol fraction had the most potent anti-inflammatory action. Additioinally the sapogenin obtained through acid hydrolysis of the butanol fraction did not show anti-inflammatory action. These findings confirm the value of Platycodi radix as a traditional Korean medicine.

  • In facioscapulohumeral muscular dystrophy (FSHD), prominent inflammatory cellular infiltrates mimicking inflammatory myopathies are often observed in muscle biopsies. We report extensive inflammatory changes in a 16-year-old girl who was genetically confirmed as to have FSHD. Immunohistochemical staining revealed that this could be clearly distinguished from inflammatory myopathies, both in terms of cell subsets and the expression of antigenic targets. Our observations strongly suggest that the inflammatory cellular infiltrates in FSHD differ from those observed in inflammatory myopathies.

  • The present study investigated the mechanisms of licochalcone B (LicB)-mediated inhibition of the inflammatory response in murine macrophages. RAW264.7 murine macrophages were cultured in the absence or presence of lipopolysacharide (LPS) with LicB. LicB suppressed the generation of nitric oxide and the pro-inflammatory cytokines interleukin (IL)-$1{\beta}$, IL-6 and tumor necrosis factor-${\alpha}$. LicB also inhibited the expression of mRNA for inducible nitric oxide synthase and pro-inflammatory cytokines induced by LPS. Moreover, LicB inhibited nuclear factor-${\kappa}B$ (NF-${\kappa}B$) and activator protein-1 translocation into the nucleus in a dose-dependent manner. Thus, LicB mainly exerts its anti-inflammatory effects by inhibiting the LPS-induced NF-${\kappa}B$ and activator protein-1 signaling pathways in macrophages, which subsequently diminishes the expression and release of various inflammatory mediators. LicB shows promise as a therapeutic agent in inflammatory diseases.

  • In an attempt to elucidate the anti-inflammatory action of ginseng total saponin, protopanaxadiol and protopanaxatriol, the anti-inflammatory activity of three compounds was investigated under various acute and chronic inflammatory models. The blood vessel permeability was slightly inhibited by total saponin and protopanaxatriol treatments. Granuloma formation induced by 2% carrageenan was inhibited by total saponin and protopanaxatriol. The cotton-pellet granuloma formation was significantly inhibited by intraperitoneal injection of total saponin. Total saponin and protopanaxadiol inhibited leukocyte emigration and protein exudation in CMC-induced pouch but protopanaxauiol increased leukocyte emigration. The swelling of rat hind paw induced by 1% carrageenan was significantly inhibited by total saponin, protopanaxadiol and protopanaxatriol both single and 2 weeks treatments. Total saponin, protopanaxadiol and protopanaxatriol decreased the anti-inflammatory activity in adrenalectomized rat. Our results suggest that total saponin, protopanaxadiol and protopanaxatriol have potent anti-inflammatory activity, this may be mediated in part through stimulation of adrenal glands.

  • Panax ginseng is one of the most universally used herbal medicines in Asian and Western countries. Most of the biological activities of ginseng are derived from its main constituents, ginsenosides. Interestingly, a number of studies have reported that ginsenosides and their metabolites/derivatives-including ginsenoside (G)-Rb1, compound K, G-Rb2, G-Rd, G-Re, G-Rg1, G-Rg3, G-Rg5, G-Rh1, G-Rh2, and G-Rp1-exert anti-inflammatory activities in inflammatory responses by suppressing the production of proinflammatory cytokines and regulating the activities of inflammatory signaling pathways, such as nuclear factor-${\kappa}B$ and activator protein-1. This review discusses recent studies regarding molecular mechanisms by which ginsenosides play critical roles in inflammatory responses and diseases, and provides evidence showing their potential to prevent and treat inflammatory diseases.

  • The aim of the present study was to elucidate whether gallic acid could modulate the inflammatory allergic reaction and to study its mechanism of action Gallic acid inhibited compound 48/80- or immunoglobulin E (IgE)-induced histamine release from mast cells. The inhibitory effect of gallic acid on the histamine release was mediated by modulation of cAMP and intracellular calcium. Gallic acid decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated pro-inflammatory cytokine gene expression and production such as TNF- ${\alpha}$ and IL-6 in human mast cells, and the inhibitory effect of gallic acid was on dependent nuclear factor- ${\kappa}$B and p38 mitogen-activated protein kinase. Our findings provide evidence that gallic acid inhibits mast cell-derived inflammatory allergic reaction by blocking histamine release and pro-inflammatory cytokine expression.

  • Equisetum hyemale L. has been prescribed widely as a traditional medicine for the treatment of inflammatory diseases such as rheumatoid arthritis, conjunctivitis, pyelonephritis. In order to identification the mechanism, we examined an antioxidant and anti-inflammatory activity of 85% methanol extract of E. hyemale. In this study E. hyemale exhibited strong scavenging effect on 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical, superoxide radical, and nitric oxide. To elucidate the anti-inflammatory properties of E. hyemale, we investigated the inhibition effects of nitric oxide and IL-6 by E. hyemale in IFN-gamma and LPS-stimulated mouse peritoneal macrophages. E. hyemale suppressed nitric oxide, IL-6 production and iNOS expression dose-dependently without notable cytotoxic activity. These data suggest that E. hyemale might be useful in inflammatory diseases by inhibiting the free radicals and inflammatory mediators.

  • Inflammation plays an important role in immune system's response to tissue injury and biological stimuli. However, excessive inflammation can cause tissue damage. Therefore, the development of naturally derived anti-inflammatory agents have received broad attention. In this study, we investigated the anti-inflammatory mechanism of Rubi Fructus (RF) extract on the mast cell-mediated inflammatory response. To determine the regulatory mechanism of RF in inflammatory reaction, we evaluated the effects of RF on secretion of interleukin (IL)-8, IL-6 and tumor necrosis factor (TNF)-α and activation of nuclear factor-κB (NF-κB) and caspase-1 in activated human mast cells-1 (HMC-1). The results showed that RF attenuated IL-8, IL-6 and TNF-α secretion in a concentration-dependent manner. Moreover, RF significantly attenuated caspase-1and NF-κB activation in activated HMC-1. Conclusively, the present results provide evidence that RF may be a promising agent for anti-inflammatory therapy.

  • Several derivatives were synthesized from fructigenine A, which was isolated from Penicillium fructigenum. The anti-inflammatory properties of fructigenine A was evaluated in vivo with a 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced mouse ear edema model and a carrageenan-induced rat paw edema model. Results showed that the anti-inflammatory activity was significantly higher with fructigenine derivatives than with indomethacin, which was used as a standard. We concluded that fructigenine derivatives could exert an anti-inflammatory effect.
