The cabbage extract of the research does not show cytotoxicity, and thus can be used safely. In an experiment performed on an animal model with liver injury induced by a drug (APAP), it could be seen that the cabbage extract exhibited the effects of protecting liver and improving liver function by effectively reducing AST and ALT which are liver injury markers, indicating that the cabbage extract is effective as a pharmaceutical composition for preventing or treating liver disease. In particular, the cabbage extract was effective in treating inflammation of the liver by reducing the expression of the inflammatory mediators iNOS and COX-2 and the proinflammatory cytokine IL-1β, which are involved in acute inflammatory reactions accompanying liver injury. In the research, an extract of cabbage heat-treated at a temperature of 100 to 150℃ had a better liver function-improving effect or anti-inflammatory effect than an extract of raw cabbage.

Objectives NJ is being used to treat inflammatory diseases in Korea. In this study, we attempted to evaluate the effects of NJ on atopic dermatitis (AD)-like lesions and mast cell-mediated allergy inflammation in vivo and in vitro. Methods and Results We investigated to ascertain the pharmacological effects of NJ on 2,4-dinitrofluorobenzene (DNFB)-induced allergic reactions under in vivo conditions. Additionally, to find possible explanations for the anti-inflammatory mechanisms of NJ, we evaluated the regulatory effects of NJ on the level of inflammatory mediators in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated human mast cells (HMC-1). Conclusions NJ inhibited the production of the inflammatory cytokines (IgE, IL-6, IL-8 and TNF-${\alpha}$) significantly in vivo and in vitro.

Immediate-type hypersensitivity is involved in many allergic diseases such as asthma, allergic rhinitis and anaphylaxis. The discovery of drugs for the treatment of allergic disease is an important subject in human health. Stimulation of mast cells releases inflammatory mediators, such as histamine and pro-inflammatory cytokines with immune regulatory properties. We investigated the effect of the aqueous extract of Schizonepeta tenuifolia (AEST) (Labiatae) on the immediate-type allergic reaction. AEST inhibited compound 48/80-induced systemic allergic reaction. AEST attenuated immunoglobulin E (IgE)-mediated skin allergic reaction and histamine release from human mast cell line (HMC-1) cells. In addition, AEST decreased the gene expression and secretion of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187 (A23187)-stimulated HMC-1 cells. Our results indicate that AEST inhibits the mast cell-derived allergic reactions and involvement of histamine and pro-inflammatory cytokines in these effects.

Because of the potent effects of lipid mediators such as prostaglandins (PGs), leukotriens (LTs) and platelet activating factor (PAF) on a variety of cells and tissues, they are considered as major contributors to the process leading to inflammation and allergy. To pursue the mechanism of anti-inflammatory activity of Lonicera japonica, we tested inhibitory effects of 7 flavonoids from Lonicera japonica on arachidonic acid cascade related enzymes, such as inflammatory phospholipase $A_2$, cyclooxygenase-1 and 2, 5-lipoxygenase, in bone marrow derived mast cell (BMMC), and lyso PAF-acetyltransferase in rat spleen microsomes. Anti-inflammatory activities of lonicera japonica are thought to be attributed at least in part to the inhibition of arachidonic acid cascade releated enzymes by flavonoids such as apigenin, luteolin quercetin.

tIn brain ischemic insult, inflammatory cells such as macrophages and lymphocytes are chemo-attracted into the brain lesion and release cytokines, resulting in an activation of microglia that are functionally equivalent to peripheral macrophages in the central nervous system. In cerebral ischemic insults, activated inflammatory cells such as microglia and macrophages may be implicated in the pattern and degree of ischemic injury by producing various bioactive mediators.

Mast cells play an important role in inflammation by functioning as a source of histamine, tryptase, and proinflammatory cytokines. Lonicera Japonica (Caprifoliaceae. Lc) has been used to treat inflammation. We investigated whether the water extract of Lonicera Japonica(Lc) inhibit production of inflammatory mediators such as tryptase and tumor-necrosis factor (TNF)-${\alpha}$, and phosphorylation of extracellular signal-regulated kinase(ERK) in trypsin-stimulated HMC-1.

The aim of the present study is to investigate the anti-inflammatory effect of a Rice Bran Ethanol Extract (RBE). Inflammation, such as a bacterial infection in vivo metabolites, such as external stimuli or internal stimuli to the defense mechanisms of the biological tissue a variety of intracellular regulatory factors deulin inflammatory TNF-${\alpha}$, IL-$1{\beta}$, IL-6, IL-8, such as proinflammatory cytokines, prostagrandin, lysosomal enzyme, free radicals are involved in a variety of mediators. The present study was designed to determine the effect of the RBE on pro-inflammatory factors such as NO, iNOS expression and TNF-${\alpha}$, IL-$1{\beta}$, IL-6 in lipopolysaccharide (LPS) - stimulated RAW264.7 macrophages cells. The cell toxicity was determined by MTS assay. To evaluate of anti-inflammatory effect of RBE, amount of NO was measured using the NO detection kit and the iNOS expression was measured by reverse transcriptase polymerase chain reaction (RT-PCR). And proinflammatory cytokines were measured by ELISA kit. As a result, the RBE reduced NO, iNOS expression and TNF-${\alpha}$, IL-$1{\beta}$, IL-6 production without cytotoxicity. Our results suggest that the RBE may have an anti-inflammatory property through suppressing inflammatory mediator productions and appears to be useful as an anti-inflammatory material.

BACKGROUND/OBJECTIVES: The traditional Korean diet is plant-based and rich in antioxidants. Previous studies have investigated the potential health benefits of individual nutrients of Korean foods. However, the cumulative effects of a Korean diet on inflammation remain poorly understood. Therefore, the aim of this study was to investigate the anti-inflammatory effects of a plant-based Korean diet. MATERIALS/METHODS: Using data from the Fifth Korean National Health and Nutrition Examination Survey, 75 individual plant food items were selected which represent over 1% of the total diet intake of the Korean diet. These items were classified into ten different food groups, and the vegetable (Veg) and fruit (Fruit) groups were studied based on their high antioxidant capacity. For comparison, a mixture of all ten groups (Mix) was prepared. To produce a model of inflammation with which to test these Veg, Fruit, and Mix plant-based Korean food extracts (PKE), RAW264.7 macrophages were treated with lipopolysaccharide (LPS). RESULTS: Levels of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$), as well as protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) were found to be lower following PKE treatment. Furthermore, PKE treatment was found to suppress tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-6 (IL-6) via the nuclear transcription factor kappa-B ($NF-{\kappa}B$) signaling pathway. Overall, the Mix group exhibited the greatest anti-inflammatory effects compared with Veg and Fruit PKE group. CONCLUSIONS: Inhibition of LPS-induced pro-inflammatory mediators by the PKE tested was found to involve an inhibition of NF-kB activation. Moreover, PKE tested have the potential to ameliorate various inflammation-related diseases by limiting the excessive production of pro-inflammatory mediators.

To investigate the therapeutic effect of a Korean herbal medicine Pulsatilla koreana as an anti-septic agent, anti-inflammatory effects of the herbal medicine were determined in lipopolysaccharide (LPS)-exposed rats. Treatment with a methanol extract from Pulsatilla koreana significantly inhibited LPS-induced inflammatory responses. Results from ELISA analysis showed that Pulsatilla koreana decreased the plasma and hepatic levels of pro-inflammatory cytokines such as IL-$1{\beta}$, IL-6, TNF-${\alpha}$ while increased the level of anti-inflammatory cytokine IL-10 in LPS-exposed rats. Pulsatilla koreana also decreased the plasma levels of other inflammatory mediators such as $NO_3{^-}/NO_2{^-}$, ICAM-1, $PGE_2$, and CINC-1 in LPS-exposed rats. Although no significant effects were observed in the phagocytic activities, the distribution of lymphocyte population was significantly shifted by the treatment with Pulsatilla koreana. All together, Pulsatilla koreana exerts anti-inflammatory activities in the immune-challenged animals implicating that this Korean herbal medicine is therapeutically useful for the treatment of inflammatory diseases like sepsis.
