Background: Callus cultivation has the advantage of producing a large amount of tissue of a plant in a laboratory regardless of the environment, for extracting an active substance. In the present study, callus formation was induced in the leaves of the succulent plant Adenium obesum (Forssk.) Roem & Schult. After callus cultivation, anti-inflammatory activity tests were conducted, because leaves and stems of A. obesum have been reported to possess biological activity. Methods and Results: In order to induce callus formation, various concentrations of plant growth factors, such as kinetin, naphtha-leneacetic acid (NAA), 6-benzyladenine (BA), and indole-3-acetic acid (IAA) were added to MS solid medium. The maximum callus proliferation was induced by mixed medium consisting of NAA ($2mg/{\ell}$) and BA ($1mg/{\ell}$). In addition, an elicitor was added to the medium under optimal conditions for initiating suspension culture. After suspension culturing, the activities of the callus extracts were compared and analyzed. The cytotoxicity and anti-inflammatory activity tests revealed that the anti-inflammatory activity of the callus extract and the content of phenolic compounds were elevated after treatment of the callus culture with the elicitior. Conclusions: A. obesum callus might be considered as potential source of biologically active anti-inflammatory material.

Objectives : The main aim of this study was to assess the comparative efficiency of two preparation types of Hwangryunhaedok decoction(HRHD-D) using distilled and mixed extraction by measuring the index components and indicators of antioxidant and anti-inflammatory effects. Methods : The antioxidant activity was assessed by comparing distilled and mixed extractions of HRHD-D using an ELISA reader. The anti-inflammatory effect was determined by measuring NO amounts in RAW 264.7 cells. The contents were analyzed with high performance liquid chromatography-diode array detector(HPLC-DAD). Results : The electron donating ability of mixed and distilled extractions obtained with 500 ppm DPPH(1,1-diphenyl-2-picrylhydrazyl assay) solution were 57.8 % and 4.2 %, respectively. The total phenolic content of mixed extraction was 6.9 times that of distilled extraction and total flavonoid content was 51.5 times higher. The anti-inflammatory effect was assessed by NO measurement, and was found to increase significantly dependent on concentration in all mixed extract concentrations(25, 50, 100, 200, $400{\mu}g/mL$), but the difference in distilled extraction by concentration was only significant at 200 and $400{\mu}g/mL$. The HPLC analysis results of mixed extract of HRHD-D showed detection of all four main active constituents of HRHD-D. However, they were not detected in the distilled extract of HRHD-D. Conclusions : Mixed extraction with distillation added to decoction of HRHD-D showed better efficacy in antioxidant and anti-inflammatory effects, and ingredient quantities compared to distilled extraction. Further stability and clinical efficacy studies for standardization of mixed extractions are required.

The present study was conducted to screen candidate probiotic strains for anti-inflammatory activity. Initially, a nitric oxide (NO) assay was used to test selected candidate probiotic strains for anti-inflammatory activity in cultures of the murine macrophage cell line, RAW 264.7. Then, the in vitro probiotic properties of the strains, including bile tolerance, acid resistance, and growth in skim milk media, were investigated. We also performed an in vitro hydrophobicity test and an intestinal adhesion assay using Caenorhabditis elegans as a surrogate in vivo model. From our screening, we obtained 4 probiotic candidate lactic acid bacteria (LAB) strains based on their anti-inflammatory activity in lipopolysaccharide (LPS)-stimulated RAW 264.7 cell cultures and the results of the in vitro and in vivo probiotic property assessments. Molecular characterization using 16S rDNA sequencing analysis identified the 4 LAB strains as Lactobacillus plantarum. The selected L. plantarum strains (CAU1054, CAU1055, CAU1064, and CAU1106) were found to possess desirable in vitro and in vivo probiotic properties, and these strains are good candidates for further investigations in animal models and human clinical studies to elucidate the mechanisms underlying their anti-inflammatory activities.

Objectives : Phyllostachys Folium is leaves of Phyllostachys nigra var. henesis $S_{TAPF}$. In the East Asian traditional medicine, the herb has been used to treat nasal bleeding, dysuria, epilepsy and etc. The present study was conducted to evaluate the anti-inflammatory effects of the Phyllostachys Folium water extracts (PFE) in vitro and in vivo model. Methods : Cell viability was measured by MTT assay after the treatment of PFE and NO production was monitored by measuring the nitrite content in culture medium. iNOS, COX-2, $I{\kappa}B$, $p-I{\kappa}B{\alpha}$ amd $NF{\kappa}B$ were detected by immunoblot analysis, and levels of cytokine were analyzed by sandwich ELISA kit. Anti-edema effect of PFE was determined in the carrageenan-induced paw edema model in rats. Results : LPS increased NO and cytokines levels compared with control, these increases were attenuated by PFE. In addition, LPS-induced pro-inflammatory proteins such as iNOS, COX-2 were down regulated by PFE. These anti-inflammatory effect of PFE results from inhibition of phosphorylation of $I{\kappa}B$ and translocation of $NF-{\kappa}B$. Conclusion : These results show that PFE has some anti-inflammatory effects which might play a role in gram-negative bacterial infection inflammation and $NF{\kappa}B$ activated diseases.
Asterias amurensis (starfish) is a marine organism that is harmful to the fishing industry, but is also a potential source of functional materials. The present study was conducted to analyze the profiles of fatty acids extracted from A. amurensis tissues and their anti-inflammatory effects on RAW264.7 macrophage cells. In different tissues, the component ratios of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids differed; particularly, polyunsaturated fatty acids such as dihomo-gamma-linolenic acid (20:3n-6) and eicosapentaenoic acid (20:5n-3) were considerably different. In lipopolysaccharide-stimulated RAW264.7 cells, fatty acids from A. amurensis skin, gonads, and digestive glands exhibited anti-inflammatory activities by reducing nitric oxide production and inducing nitric oxide synthase gene expression. Asterias amurensis fatty acids effectively suppressed the expression of inflammatory cytokines such as tumor necrosis $factor-{\alpha}$, interleukin-$1{\beta}$, and interleukin-6 in lipopolysaccharide-stimulated cells. Cyclooxygenase-2 and prostaglandin $E_2$, which are critical inflammation biomarkers, were also significantly suppressed. Furthermore, A. amurensis fatty acids reduced the phosphorylation of nuclear $factor-{\kappa}B$ p-65, p38, extracellular signal-related kinase 1/2, and c-Jun N-terminal kinase, indicating that these fatty acids ameliorated inflammation through the nuclear $factor-{\kappa}B$ and mitogen-activated protein kinase pathways. These results provide insight into the anti-inflammatory mechanism of A. amurensis fatty acids on immune cells and suggest that the species is a potential source of anti-inflammatory molecules.

Phaseolus aureus (mung bean), Leguminosae, has been used as an antidote from the ancient time. Especially, it has been widely used for cleaning face and skin in oriental countries. Although several constituents such as fatty acids, phytoallexin and phaseol derivatives were reported in P. aureus and related species including seedlings, there has been a few report to describe its biological activity. Therefore, in this investigation, the ethanol extract from P. aureus was obtained and its biological activities including the antioxidative and anti-inflammatory activities were studied. The 70% ethanol extract from P. aureus showed dose-dependent antioxidative activity (52.3% inhibition at 4 mg/ml) against lipid peroxidation assay, while the extract did not show the inhibitory activity of superoxide radical formation. The extract also showed the topical anti-inflammatory activity against croton-oil and arachidonic acid induced mouse ear edema test (18-19% inhibition at 7.5 mg/ear) as well as mild inhibitory activity against picryl chloride induced delayed hypersensitivity in mouse. For investigating active principles, vitexin and isovitexin (apigenin C-glycoside) as flavonoids, and adenosine were isolated from the extract using silica gel chromatography. The actual contents of vitexin and isovitexin were found to be 3.7 and 2.4 mg/g extract, respectively. Vitexin and isovitexin showed the antioxidative activity. They showed the topical anti-inflammatory activity, although the activities were not potent compared to the reference compounds. These results suggested that vitexin and isovitexin may be, at least in part, the compounds contributing the antioxidative activity in vitro and the topical anti-inflammatory activity of P. aureus in vivo. All results of present study might be one of the scientific rationale in using mung bean for skin care from the ancient time.

Oxidative stress and inflammation are important events in the development of chronic inflammatory diseases including arthritis, atherosclerosis, diabetes, hypertension. Cynomorium songaricum (CS) has been used as a traditional Korean herbal medicine, and it is currently used in traditional clinics to treat frequent urination, spermatorrhea, weakness of the sinews and constipation in the folk medicine. The aim of this study was to determine whether fractionated extracts of CS inhibit free radical generation such as DPPH radical, superoxide radical, nitric oxide and peroxynitrite, production of nitrite an index of NO, $PGE_2$, iNOS, COX-2 and pro-inflammatory cytokines in lipopolysaccharide (LPS)-treated RAW 264.7 macrophages. Cytotoxic activity of extracts on RAW 264.7 cells was measured using 5-(3-caroboxymeth-oxyphenyl)-2H-tetra-zolium inner salt (MTS) assay. Our results indicated that the most superior extract which scavenged DPPH radical, reactive oxygen species (ROS) and RNS was CS ethyl acetate extract (CSEA). Moreover, CSEA significantly inhibited the LPS-induced NO, $PGE_2$ production and iNOS, COX-2 expression accompanied by an attenuation of TNF-$\alpha$, IL-$1{\beta}$ and IL-6 formation in macrophages. Furthermore, CSEA treatment also blocked LPS-induced intracellular ROS production and the activation of NF-${\kappa}B$. These findings indicate that CSEA inhibits the production of pro-inflammatory mediators and cytokines via the suppression of ROS production and NF-${\kappa}B$ activation. Take together, these results indicate that CSEA has the potential for use as an natural anti-oxidant and an agent of anti-chronic inflammatory diseases.
This paper reports in vitro cytotoxic, anti-inflammatory and adipocyte diffentiation with adipogenic effects of coumarins inophyllum D (1) and calanone (2), and a chromanone carboxylic acid namely isocordato-oblongic acid (3) isolated from Calophyllum symingtonianum as well as a biflavonoid morelloflavone (4) isolated from Garcinia prainiana on MCF-7 breast adenocarcinoma RAW 264.7 macrophages and 3T3-L1 preadipocytes cells, respectively. The cytotoxicity study on MCF-7 cell was conducted by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Meanwhile, the study of anti-inflammatory effects in RAW 264.7 macrophages and adipogenic effects on 3T3-L1 pre-adipocytes were conducted through nitrite determination assay and induction of adipocyte differentiation, respectively. In the cytotoxicity study, inophyllum D (1) was the only compounds that exhibited significant cytotoxic effect against MCF-7 cell with $IC_{50}$ of $84{\mu}g/mL$. Further, all by inhibiting the compounds have shown anti-inflammatory effects in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages of nitrite concentration with production. In addition, the compounds also exhibited adipogenic effects on 3T3-L1 pre-adipocytes by stimulating lipid formation. Thus, this study may provide significant input in discovery of the potential effects cytotoxic, anti-inflammatory and adipogenic agents.
The antioxidative activities and anti-inflammatory effects of rice bran and wheat bran were investigated. To determine the antioxidant activity, total phenolic content. DPPH reaction, ABTS reaction and FRAP assay were tested. To investigate the anti-inflammatory effect, the inhibition of NO production, IL-6 production and TNF-${\alpha}$ production were observed. The total phenolic contents were 46.4 mg/g in the BuOH fraction of rice bran (RBB) and 69.0 mg/g in BuOH fraction of wheat bran (WBB). EtOAc fraction of rice bran (RBE), EtOAc fraction of wheat bran (WBE), RBB and WBB showed high radical scavenging activity at a concentration of 5 mg/ml. Scavenging activity of DPPH radical were 89.04% in RBB and 91.53% in WBE. Scavenging activity of ABTS radical were 88.53% in RBB and 90.39% in WBB. In case of FRAP assay, RBE reduced 0.805 mM/mg of Fe2+ and WBE reduced 1.521 mM/mg of Fe2+. RBB, RBE, WBB and WBE showed concentration dependent inhibition of LPS induced NO production (RBE: 57.38%, WBE: 76.85%), IL-6 production (RBE: 92.08%, WBB: 92.57%), TNF-α production (RBE: 86.33%, WBE: 85.05%) at a concentration of 100 μg/ml of each fraction. These results showed that RBB, RBE, WBB and WBE have strong antioxidative activities and anti-inflammatory effects and show the possibilities of a new natural antioxidants and anti-inflammatory medicines.
For effective management of atopic dermatitis, it is important to introduce a therapeutic agent although having the fewest side effects, has the greatest anti- inflammatory effect. In the course of screening anti-inflammatory agents, we obtained BSASM composed of several plant extracts. This study was designed to investigate anti-inflammatory and immunomodulatory effects of BSASM. As a first step, $NF-{\kappa}B$ luciferase reporter assay was performed to know the involvement of BSASM in the production of proinflammatory cytokines because $NF-{\kappa}B$ element has been known to play a major role in expression of cytokine genes such as interleukin-8 (IL-8) or tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$. LPS (lipolysaccharide)-induced $NF-{\kappa}B$ activation was inhibited by BSASM. In addition, we found the fact that BSASM inhibits LPS-induced produced production of IL-8 and $TNF-{\alpha}$ proinflammatory cytokines, indicating BSASM has anti-inflammatory effect. In interleukin-2 (IL-2) luciferase reporter assay in Jurkat T cells, BSASM reduced PHA (Phytohemagglutinin)-induced IL-2 luciferase activity, suggesting the possibility that BSASM might also have an immunomodulatory function in T cell-mediated immune response. Based on these results, we suggest the possibility that BSASM can be introduced to improve symptom of immune-related skin diseases, namely, atopic dermatitis.
