  • Atopic dermatitis (AD) is a common chronic inflammatory disease associated with a cutaneous hypersensitivity reaction to an allergen. Although the incidence of AD is increasing these days, therapeutics has yet to be developed for its treatment. The aim of this study was conducted in order to compare and investigate the characteristic between the Castanea crenata inner shell extract (CS) and the Castanea crenata inner shell extract fermented by Lactobacillus bifermentans (FCS) for an anti-atopic medication. The total polyphenol and flavonoid contents were similar to CS and FCS. In the DPPH and superoxide anion radical scavenging, the CS and FCS had the potential for antioxidant activities. Both of them did not exhibit cytotoxicity to HS68 cells. The evaluation of the anti-inflammatory activity in Raw264.7 cells demonstrated that the FCS has inhibited the LPS-induced production of nitric oxide as compared to the CS. The anti-atopic dermatitis test was done through the induction of DNCB in AD hairless mice. The FCS has inhibited the development of the atopic dermatitis-like skin lesion by transdermal water loss, melanin and erythema of the skin as compared to the CS. Moreover, the pro-inflammatory cytokine IL-$1{\beta}$ and TNF-${\alpha}$ production in hairless mice were inhibited by the FCS treatment. It indicates that the fermentation of the Castanea crenata inner shell has the potential for the treatment of atopic dermatitis.

  • G. japonicum is a perennial hem and the flowering plant has been used as a diuretic and an astringent in Japan and China. However, little information is available about the anti-inflammatory action of G. japonicum. Therefore, the objective of this study was to investigate the antiinflammatory action of fractions from G. japonicum methanol extract. Inhibition of NO production was observed when cells were cotreated with fractions of G. japonicum and lipopolysaccharide. We observed that ethyl acetate fraction of G. japonicum inhibited NO production by LPS-activated RAW 264.7 cells, and that the suppression induced by ethyl acetate fraction of G. japonicum was associated with antioxidant activity and direct NO clearance. In addition, only ethyl acetate fraction of G. japonicum inhibited stimulated $PGE_2,\;TNF-\alpha,\;IL-1\beta$ production, whereas water and methyl chloride fractions showed no such effects. The ethyl acetate fraction of G. japonicum methanol extract showed a remarkable scavenging activity on the 1,1-diphenyl-2 picrylhydrazyl radical. Based on the results, ethyl acetate fraction of G. japonicum may be useful source as natural antioxidants and antiinflammation. Therefore, the results obtained from this study provide an alternative protective mechanism of ethyl acetate fraction of G. japonicum and provide information on the potential use of ethyl acetate fraction of G. japonicum in chemoprevention or pathogenic conditions related to overproduction of NO and $PGE_2$. However, the mechanism of the inflammatory effect must be evaluated through various parameters for induction of NO production.

  • Objective: This study aimed to evaluate the protective effects of Socheongryong-tang (SCRT) on elastase-induced lung injury. Materials and Methods: The extract of SCRT was treated to A549 cells and elastase-induced COPD mice model. Then, various parameters such as cell-based cytoprotective activity and histopathological findings were analyzed. Results: SCRT showed a protective effect on elastase-induced cytotoxicity in A549 cells. This effect was correlated with analysis for caspase 3 levels, collagen and elastin contents, and gene expression of TNF-${\alpha}$ and IL-$1{\beta}$ in A549 cells. SCRT treatment also revealed the protective effect on elastase-induced COPD mice model. This effect was evidenced via histopathological findings including immunofluoresence stains against elastin, collagen, and caspase 3, and protein level of Cdc2, cyclin B1, and phospho-Erk1/2 in lung tissue. Conclusion: These data suggest that SCRT has pharmaceutical properties on COPD. This study provides scientific evidence for the efficacy of SCRT for clinical application to patients with COPD.

  • Broussonetia papyrifera and Lonicera japonica have long been used in the treatment of inflammatory disorders in Chinese medicine, especially respiratory inflammation. Previously, a new phytoformula (BL) containing B. papyrifera and L. japonica was found to exert strong anti-inflammatory activity against several animal models of inflammation, especially against an animal model of acute bronchitis. In the present investigation, the effects of BL on animal models of septic inflammation and chronic bronchitis are examined. Against lipopolysaccharide (LPS)-induced septic inflammation in mice, BL (200-400 mg/kg) reduced the induction of some important proinflammatory cytokines. At 1 h after LPS treatment, BL was found to considerably inhibit TNF-${\alpha}$ production when measured by cytokine array. At 3 h after LPS treatment, BL inhibited the induction of several proinflammatory cytokines, including IFN-${\gamma}$ and IL-$1{\beta}$, although dexamethasone, which was used as a reference, showed a higher inhibitory action on these biomarkers. Against chronic bronchitis induced by LPS/elastase instillation in rats for 4 weeks, BL (200-400 mg/kg/day) significantly inhibited cell recruitment in bronchoalveolar lavage fluid. Furthermore, BL considerably reduced lung injury, as revealed by histological observation. Taken together, these results indicate that BL may have a potential to treat systemic septic inflammation as well as chronic bronchitis.

  • We previously reported that the extract from cuttlebone (CB) has wound healing effect in burned lesion of rat. In present study, the main component of CB extract was analyzed and its wound healing activity was evaluated by using in vitro acute inflammation model. The extract of CB stimulated macrophages to increase the production of TNF-${\alpha}$. The extract also enhanced the production of TGF-${\beta}$ and VEGF, which were involved in angiogenesis and fibroblast activation. The treatment with CB extract enhanced proliferation of murine fibroblast. CB extract also induced the activation of fibroblast to increase the secretion of matrix metalloproteases 1 (MMP1). The constituent of CB extract which has wound healing activity was identified as chitin by HPLC analysis. The mechanism that the CB extract helps to promote healing of burned lesion is associated with that chitin in CB extracts stimulated wound skins to induce acute inflammation and to promoted cell proliferation and MMP expression in fibroblast. Our results suggest that CB or chitin can be a new candidate material for the treatment of skin wound such as ulcer and burn.

  • Objectives: Thymoquinone (TQ) is one of the active ingredients of herbal plants such as Nigella sativa L. (NS) which has beneficial effects on the body. The beneficial effects of TQ on the cardiovascular system have reported. This study aimed to investigate the effect of TQ on cardiac fibrosis and permeability, serum and tissue concentration of inflammatory markers and oxidative stress status in chronic lipopolysaccharide exposure in male rats. Methods: Seventy male Wistar rats were randomly divided into five groups as follows: (1) control; (2) LPS (1 mg/kg/day); (3-5) LPS + TQ with three doses of 2, 5 and 10 mg/kg (n=14 in each group). After 3 weeks, serum and cardiac levels of $IL-1{\beta}$, $TNF-{\alpha}$ and nitric oxide (NO) metabolites, and cardiac levels of malondialdehyde (MDA), total thiol groups, catalase (CAT) and superoxide dismutase (SOD) activities, permeability of heart tissue (evaluated by Evans blue dye method) and myocardial fibrosis were determined, histologically. Results: LPS administration induced myocardial and perivascular fibrosis and increased cardiac oxidative stress (MDA), inflammatory markers and heart permeability, while, reduced anti-oxidative enzymes (SOD and CAT) and the total thiol group. Administration of TQ significantly attenuated these observations. Conclusion: TQ improved myocardial and perivascular fibrosis through suppression of chronic inflammation and improving oxidative stress status and can be considered for attenuation of cardiac fibrosis in conditions with chronic low-grade inflammation.

  • This study evaluated the protective effects of a combination of eight B. abortus recombinant proteins that were cloned and expressed into a pMal vector system and $DH5{\alpha}$: nucleoside diphosphate kinase (rNdk), 50S ribosomal protein (rL7/L12), malate dehydrogenase (rMDH), DNA starvation/stationary phase protection protein (rDps), elongation factor (rTsf), arginase (rRocF), superoxide dismutase (rSodC), and riboflavin synthase subunit beta (rRibH). The proteins were induced, purified, and administered intraperitoneally into BALB/c mice. The mice were immunized three times at weeks 0, 2, and 5 and then infected intraperitoneally (IP) with $5{\times}10^4CFU$ of virulent B. abortus 544 one week after the last immunization. The spleens were collected and the bacterial burden was evaluated at four weeks post-infection. The results showed that this combination produced a significant reduction of the bacterial burden in the spleen with a log reduction of 1.01 compared to the PBS group. Cytokine analysis revealed induction of the cell-mediated immune response in that TNF (tumor necrosis factor) and proinflammatory cytokines IL-6 (Interleukin 6) and MCP-1 (macrophage chemoattractant protein-1) were elevated significantly. In summary, vaccination with a combination of eight different proteins induced a significant protective effect indicative of a cell mediated immune response.
