  • This study aimed to evaluate the anti-adipogenic and anti-inflammation effects of extract from Maclura tricuspidata twig fermented with Ganoderma lucidum mycelium (EMFG) in 3T3-L1 preadipocytes. 3T3-L1 adipocytes were treated with 100, 200, 300 ㎍/mL of EMFG. The result showed that EMFG dose-dependently inhibited the accumulation of intracellular lipid content in differentiated 3T3-L1 adipocytes and enhanced increase of adiponectin release and inhibition of leptin release. EMFG treatment reduced expression of adipogenic transcriptional factor such as peroxisome proliferator-activated receptor γ (PPARγ), CCAAT-enhancer-binding protein α (C/EBPα). EMFG also decreased production of lipopolysaccharide (LPS)-induced inflammatory cytokine [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1)] and the protein expression of cyclooxygenase-2 (COX-2) and inducible NOS (iNOS) in differentiated 3T3-L1 adipocytes. The study demonstrated that EMFG inhibited adipogenesis and inflammation in a dose-dependent manner. These findings suggest that EMFG may have potential as an anti-obesity and anti-metabolic disease agent that works by inhibiting adipogenesis and inflammation.

  • Objective: Rutin, also called vitamin P, is a flavonoids from plants. Previous studies have indicated that rutin can alleviate the injury of tissues and cells by inhibiting oxidative stress and ameliorating inflammation. There is no report on the protective effects of rutin on goat rumen epithelial cells (GRECs) at present. Hence, we investigated whether rutin can alleviate lipopolysaccharide (LPS)-induced damage in GRECs. Methods: GRECs were cultured in basal medium or basal medium containing 1 ㎍/mL LPS, or 1 ㎍/mL LPS and 20 ㎍/mL rutin. Six replicates were performed for each group. After 3-h culture, the GRECs were harvested to detect the relevant parameters. Results: Rutin significantly enhanced the cell activity (p<0.05) and transepithelial electrical resistance (TEER) (p<0.01) and significantly reduced the apoptosis rate (p<0.05) of LPS-induced GRECs. Rutin significantly increased superoxide dismutase, glutathione peroxidase, and catalase activity (p<0.01) and significantly decreased lactate dehydrogenase activity and reactive oxygen species and malondialdehyde (MDA) levels in LPS-induced GRECs (p<0.01). The mRNA and protein levels of interleukin 6 (IL-6), IL-1β, and C-X-C motif chemokine ligand 8 (CXCL8) and the mRNA level of tumor necrosis factor-α (TNF-α) and chemokine C-C motif ligand 5 (CCL5) were significantly increased in LPS-induced GRECs (p<0.05 or p<0.01), while rutin supplementation significantly decreased the mRNA and protein levels of IL-6, TNF-α, and CXCL8 in LPS-induced GRECs (p<0.05 or p<0.01). The mRNA level of toll-like receptor 2 (TLR2), and the mRNA and protein levels of TLR4 and nuclear factor κB (NF-κB) was significantly improved in LPS-induced GRECs (p<0.05 or p<0.01), whereas rutin supplementation could significantly reduce the mRNA and protein levels of TLR4 (p<0.05 or p<0.01). In addition, rutin had a tendency of decreasing the protein levels of CXCL6, NF-κB, and inhibitor of nuclear factor kappa-B alpha (0.05

  • Background: Several studies have demonstrated that conventional hypothermic cardiopulmonary bypass (CPB) causes cellular injury, abnormal responses in peripheral vascular beds and increased postoperative bleeding, whereas normothermic CPB provides protection of the hypothermic-induced effects and better cardiac recovery. The present study was prospectively performed to compare the effects of normothermic CPB to those of hypothermic CPB on the inflammatory and hematologic responses during cardiac surgery. Material and Method: Thirty-four adult patients scheduled for elective cardiac surgery were randomly assigned to hypothermic CPB (nasopharyngeal temperature $26~28^{\circ}C,$ n=17) or normothermic CPB (nasopharyngeal $temperature>35.5^{\circ}C,$ n=17) group. In both groups, cold $(4^{\circ}C)$ crystalloid cardioplegia was applied for myocardial protection. Blood samples were drawn from radial artery before (Pre-CPB), 10 minutes after starting (CPB-10) and immediately after ending (CPB-OFF) CPB. Total leukocyte and platelet counts, interleukin-6 (IL-6) level(expressed as percent to the baseline of Pre-CPB), D-dimer level, protein C and protein S activity were measured with the blood samples. The amount of bleeding for postoperative 24 hours and blood transfusion after operation were also assessed. All parameters were compared between the two groups. Result: The total leukocyte counts $(10,032\pm65/mm^3)$ and the increased ratio of IL-6 $(353\pm7.0%)$ at CPB-OFF in the normothermic group were higher than that $(7,254\pm48/mm^3$ and $298\pm7.3%)$ of the hypothermic group(p=0.02 and p=0.03). In the normothermic group, protein C activity $(32\pm3.8%)$ and protein S activity $(35\pm4.1%)$ at CPB-OFF were significantly lower than that $(45\pm4.3%$ and $51\pm3.8%)$ of the hypothermic group (p=0.04 and p=0.009). However, there were no differences in platelet counts and D-dimer concentration. In the normothermic group, the amount of bleeding for postoperative 24 hours $(850\pm23.2$ mL) and requirements for blood transfusion after operation such as packed cell $(1,402\pm20.5$ mL), fresh frozen plasma $(970\pm20.8$ mL) and platelet $(252\pm6.4$ mL) were higher than that $(530\pm21.5$ mL, $696\pm15.7$ mL, $603\pm18.2$ mL and $50\pm0.0$ mL) of the hypothermic group. Conclusion: These results indicate that normothermic CPB with cold crystalloid cardioplegia was associated with higher increase in inflammatory response, hemostatic abnormalities and postoperative bleeding problem than moderate hypothermic CPB.

  • Background : It is now thought that the earliest manifestation of idiopathic pulmonary fibrosis is alveolitis, that is, an accumulation of inflammatory and immune effector cells within alveolar walls and spaces. Inflammatory cells including alveolar macrophages and resident normal pulmonary tissue cells participate through the release of many variable mediators such as inflammatory growth factors and cytokines, which contribute to tissue damage and finally cause chronic pulmonary inflammation and fibrosis. This study was performed to investigate the source and distribution pattern of transforming growth factor-${\beta}_1$(TGF-${\beta}_1$), platelet derived growth factor(PDGF), basic fibroblast growth factor(bFGF), interleukin 1(IL-1), interleukin 6(IL-6), tumor necrosis factor-$\alpha$ (TNF-$\alpha$) and the role of these mediators on bleomycin(BLM)-induced pulmonary injury and fibrosis in rats. Method : Wistar rats were divided into three groups(control group, BLM treated group, BLM and vitamine E treated group). Animals were sacrificed periodically at 1, 2, 3, 4, 5, 7, 14, 21, 28 days after saline or BLM administration. The effects were compared to the results of bronchoalveolar lavage fluid analysis, light microscopic findings, immunohistochemical stains for six different mediators(TGF-${\beta}_1$, PDGF, bFGF, IL-1, IL-6 and TNF-$\alpha$) and mRNA in situ hybridization for TGF-${\beta}_1$. Results : IL-1 and IL-6 are maximally expressed at postbleomycin 1~7th day which are mainly produced by neutrophils and bronchiolar epithelium. It is thought that they induce recruitment of inflammatory cells at the injury site. The expression of IL-1 and IL-6 at the bronchiolar epithelium within 7th day is an indirect evidence of contribution of bronchiolar epithelial cells to promote and maintain the inflammatory and immune responses adjacent to the airways. TNF-$\alpha$ is mainly produced by neutrophils and bronchiolar epithelial cells during 1~5th day, alveolar macrophages during 7~28th day. At the earlier period, TNF-$\alpha$ causes recruitment of inflammatory cells at the injury site and later stimulates pulmonary fibrosis. The main secreting cells of TGF-${\beta}_1$ are alveolar macrophages and bronchiolar epithelium and the target is pulmonary fibroblasts and extracellular matrix. TGF-${\beta}_1$ and PDGF stimulate proliferation of pulmonary fibroblasts and TGF-${\beta}_1$ and bFGF incite the fibroblasts to produce extracellular matrix. The vitamine E and BLM treated group shows few positive cells(p<0.05). Conclusion : After endothelial and epithelial injury, the neutrophils and bronchiolar epithelium secrete IL-1, IL-6, TNF-$\alpha$ which induce infiltration of many neutrophils. It is thought that variable enzymes and $O_2$ radicals released by these neutrophils cause destruction of normal lung architecture and progression of pulmonary fibrosis. At the 7~28th day, TGF-${\beta}_1$, PDGF, bFGF, TNF-$\alpha$ secreted by alveolar macrophages sting pulmonary fibroblasts into proliferating with increased production of extracellular matrix and finally, they make progression of pulmonary fibrosis. TNF-$\alpha$ compares quite important with TGF-${\beta}_1$ to cause pulmonary fibrosis. Vitamine E seems to decrease the extent of BLM induced pulmonary fibrosis.

  • Mast cells, the central effector cells involved in the allergic response, release histamine, arachidonic acid, and proinflammatory cytokines. We investigated the effect of the ethyl acetate fraction (EA), derived from Korean rice wine lees, on RBL-2H3 cell degranulation and passive cutaneous anaphylaxis in an animal model. The EA fraction suppressed the release of beta-hexosaminidase, a marker of degranulation, and the mRNA expression of interleukin-3 (IL-3) and IL-13. EA also successfully suppressed the passive cutaneous anaphylaxis (PCA) reaction in mice in a dose-dependent manner. These results suggest that EA can inhibit mast cell degranulation through the inhibition of IL-3 and IL-13 mRNA expression, and that EA may potentially serve as an anti-allergic agent.

  • Type of dietary direct-fed microbials (DFMs) or poultry litter could directly influence the composition of gut microbiota. Gut microbiota plays an important role in shaping the developing immune system and maintaining the homeostasis of the mature immune system in mammal and chickens. The present study was carried out to investigate the interaction among litter, DFMs and immunity in broiler chickens exposed to a field-simulated environment. Immune status of broiler chickens was assessed by serum antibodies against Eimeria spp. and Clostridium spp. and intestinal cytokine mRNA expression. The current experimental design had a $3{\times}2$ factorial arrangement of treatments with three types of litter, i.e., fresh litter or used litter that was obtained from a farm with no disease outbreak (used litter) or a farm with history of a gangrenous dermatitis outbreak (GD litter), and two dietary treatments with or without DFMs. It was found that either DFM addition or type of litter significantly affected anticoccidial antibody levels of broiler chickens at d 42. In general, dietary DFMs increased the anticoccidial antibodies in the fresh-litter raised chickens, but lowered the levels in the GD-litter raised chickens. Serum antibodies against Clostridium perfringens ${\alpha}$-toxin were significantly (p<0.05) higher in chickens raised on GD litter compared with those raised on fresh litter. Cytokine mRNA expression was significantly (p<0.05) altered by either the type of litter or DFMs. Of interest, dietary DFMs lowered interferon-${\gamma}$, interleukin 1beta, and CXCLi2 cytokine mRNA expression in chickens raised on fresh litter but increased them in GD-litter raised chickens. In conclusion, dietary DFMs modulate various immune parameters of broiler chickens, but the DFM-mediated effects were dependent upon the type of litter on which chickens were raised.

  • The effects of Sparassis crispa extracts fermented with isolated strain from S. crispa on antioxidant and immunological activities were determined. S. crispa extracts fermented with Meyerozyma guilliermondii FM showed significantly higher total phenol contents and DPPH radical scavenging activities compared to those fermented with lactic acid bacteria. In methotrexate-induced immunosuppressed rats, reduced levels of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-2, and immunoglobulin E (IgE) and increased levels of IL-10 were detected in S. crispa extract injected groups regardless of fermentation. We confirmed that rats treated with S. crispa fermented with M. guilliermondii FM showed higher blood leukocyte contents compared to other treatments. These results suggest that M. guilliermondii FM has high potential as a starter culture for fermentation of S. crispa extracts with increased antioxidant and immunological activities.

  • Objectives: Chungpaesagan-tang (CPSGT), which is frequently used for treating patients of cerebrovascular disease, has not been reported by clinical doctors concerning the effect of neuronal aptosis caused by brain ischemia. To study the effect of CPSGT on focal cerebral ischemia in normal and diabetic rats and SHR, focal cerebral ischemia was induced by transient MCAO, and after onset CPSGT was administrated. Methods: Rats (Sprague-Dawley) were divided into four groups: sham-operated group, MCA-occluded group, CPSGT­administrated group after MCA occlusion, and normal group. The MCA was occluded by intraluminal method. CPSGT was administrated orally twice (l and 4 hours) after middle cerebral artery occlusion. All groups were sacrificed at 24 hours after the surgery. The brain tissue Was stained with $2\%$ triphenyl tetrazolium chloride (TTC) or $1\%$ cresyl violet solution, to examine effect of CPSGT on ischemic brain tissue. The blood samples were obtained from the heart.~. Tumor necrosis $factor-\alpha$ level and interleukin-6 level of serum was measured from sera using enzyme-linked immunoabsorbent assay (ELISA). Then changes of immunohistochemical expression of $TNF-\alpha$ in ischemic damaged areas were observed. Results: In NC+MCAO+CP and DM+MCAO+CP, CPSGT significantly (p<0.01) decreased the number of neuron cells compared to the control group. CPSGT markedly reduced (p<0.01) the infarct size of the forebrain in distance from the interaural line on cerebral ischemia in diabetic rats. CPSGT significantly reduced the $TNF-\alpha$ expression in penumbra region of damaged hemisphere in diabetic rats. Conclusions: CPSGT had a protective effect on cerebral ischemia in SD rats, especially in diabetic rats compared with normal SD rats.

  • Objectives : We investigated the effect of Dohongsamul-tang (DHSMT) on the production of various cytokines in lipopolysaccaride (LPS) stimulated peripheral mononuclear cells (PBMCs) from CI patients. Methods: Cell viability was determined using MTT assay. ELISA was carried out for investigating $TNF-{\alpha}$, $IL-1{\beta}$, IL-6, IL-8, IL-4, and $TGF-{\beta}$ 1 Results : The amount of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, IL-6, IL-8, IL-4, and transforming growth factor(TGF)-${\beta}$ 1 in PBMC culture supernatant significantly increased in the LPS treated cells compared to unstimulated cells. We show that DHSMT inhibited the production of TNF-${\alpha}$, IL-1${\beta}$, IL-6, IL-8, and IL-4 induced by LPS in a dose dependent manner. The maximal inhibition rate of the TNF-${\alpha}$, IL-1${\beta}$, IL-6, IL-8, and IL-4 production by pretreatment of DHSMT (1.0mg/ml) was 38.52 ${\pm}$ 2.5% (P < 0.01), 44.02 ${\pm}$ 3.5% (P < 0.05), 45.32 ${\pm}$ 2.3% (P < 0.01), 42.30 ${\pm}$ 3.1% (P < 0.05), and 49.70 ${\pm}$ 3.1%(P &lt; 0.05), respectively. On the other hand, DMSMT significantly increased the LPS-induced TGF-${\beta}$ 1 production(P<0.05). Conclusions : Taken together. these results suggest that DHSMT might have regulatory effects on cytokine production, which might explain its beneficial effect in the treatment of CI.

  • We examined that the protective effects of ANX1 on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced skin inflammation in animal models using a Tat-ANX1 protein. Topical application of the Tat-ANX1 protein markedly inhibited TPA-induced ear edema and expression levels of cyclooxygenase-2 (COX-2) as well as pro-inflammatory cytokines such as interleukin-1 beta (IL-$1{\beta}$), IL-6, and tumor necrosis factor-alpha (TNF-${\alpha}$). Also, application of Tat-ANX1 protein significantly inhibited nuclear translocation of nuclear factor-kappa B (NF-${\kappa}B$) and phosphorylation of p38 and extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase (MAPK) in TPA-treated mice ears. The results indicate that Tat-ANX1 protein inhibits the inflammatory response by blocking NF-${\kappa}B$ and MAPK activation in TPA-induced mice ears. Therefore, the Tat-ANX1 protein may be useful as a therapeutic agent against inflammatory skin diseases.
