The antinociceptive effect of nicotine administered intracereboventricularly (i.c.v.) or intrathecally (i.t) in several pain models was examined in the present study. We found that i.t. treatment with nicotine (from 5 to 20 g) dose-dependently blocked pain behavior revealed during the second phase, but not during the first phase in the formalin test. In addition, i.c.v. treatment with nicotine (from 0.1 to $10\;{\mu}g$) dose-dependently attenuated pain behavior revealed during both the first and second phases. In addition to the formalin test, nicotine administered i.c.v. or i.t. attenuated acetic acid-induced writhing response. Furthermore, i.c.v. or i.t. administration of nicotine did not cause licking, scratching and biting responses induced by substance P, glutamate, TNF-${\alpha}$(100 pg), IL-$1{\beta}$(100 pg) and INF-${\gamma}$ (100 pg) injectied i.t. The antinociception induced by supraspinally-administered nicotine appears to be more effective than that resulting from spinally administered nicotine. Our results suggest that nicotine administration induces antinociception by acting on the central nervous system and has differing antinociceptive profiles according to the various pain models.

Objective : Daehwangmokdanpi-Tang (DWT) has been frequently used as a remedy for antiinflamation. To evaluate effect of acute pancreatitis by DWT, we examined the effects of DWT on the cholecystokinin-octapeptide (CCK)-induced acute pancreatitis (AP) in rats. Methods : Male Wistar rats weighing 200 to 250 g were divided into three groups. Normal untreated group, in treatment with DWT group; DWT was administered orally, followed by $75\;{\mu}g/kg$ CCK subcutaneously three times, after 1, 3 and 5 h. This whole procedure was repeated for 5 days. In treatment with saline group, the protocol was the same as in treatment group with DWT. Results : The author determined the pancreatic weight/body weight ratio, the levels of pancreatic HSP (heat shock protein)60 and HSP72 and the secretion of pro-inflammatory cytokines. Repeated CCK treatment resulted in the typical laboratory and morphological changes of experimentally induced pancreatitis. DWT was significantly decreased the pancreatic weight/body weight ratio in CCK-induced AP. Futhermore, The author demonstrated that DWT increased HSP60 and HSP72 compared with CCK-induced AP. Additionally, the secretion of $IL-1{\beta}\;and\;TNF-{\alpha}$ and the levels of amylase and lipase were lower than that saline. Conclusions : These results suggested that DWT may has a protective effect against CCK-induced AP.

Anti-inflammatory potential of the enzymatic extract prepared by Kojizyme (ECK), a component of brown seaweeds Ecklonia cava (Alariaceae, Phaeophyta) in vivo was investigated. For the application of mouse ear edema model, 12-O-tetradecanoylphorbol acetate (TPA) was used, a topical inducer of a long-lasting inflammatory response. Our results demonstrated that ECK inhibited ear edema when topically applied to mouse ear skin. In histological evaluation, the inhibition activity of ECK on TPA-induced inflammation is similar to that of dexamethasone, although less strong. In addition, the mRNA expression levels of IL-$1{\beta}$, IFN-$\gamma$, TNF-$\alpha$, and cyclooxygenase-2 (COX2) and the immunoreactivity to inducible nitric oxide synthase (iNOS) and COX2 expressed mainly in inflammatory cells were down-regulated by ECK. These results indicate that ECK has anti-inflammatory effects through the inhibition of Th1 cytokines and 2 inducers of inflammation in TPA-induced ear skin edema.

This study was designed to investigate the antioxidant activities of the ethanol extracts (GBE) of grape branches (Campbell Early). The total polyphenol and flavonoid content of GBE was $201.42{\pm}4.16$ and $11.85{\pm}0.44mg\;GAE/g$, respectively. The antioxidant activity of GBE was measured using the ABTS and DPPH assays, and the $IC_{50}$ values were $45.60{\pm}0.09$ and $299.13{\pm}0.22$, respectively. GBE inhibited the production of pro-inflammatory mediators (NO, iNOS, $PGE_2$, COX-2, $IL-1{\beta}$, and IL-6) in lipopolysaccharide-stimulated RAW 264.7 macrophages in a dose-dependent manner. Moreover, GBE treatment significantly suppressed the production of $TNF-{\alpha}$ and IL-6 cytokines in phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated HMC-1 human mast cells. Furthermore, the administration of GBE markedly inhibited the scratching behavior induced by the compound 48/80 in ICR mice. These results suggested that GBE has potential as a therapeutic agent against inflammation and itch-related skin diseases.

Background: Cytokine-mediated ex vivo expansion has been proposed as a means of increasing the number of cord blood (CB) hematopoietic stem cells for transplantation. As well as stem cell number, stromal cells are necessary for functional maturation of hematopoiesis. The purpose of this study was to analyze the development of stromal cells during ex vivo expansion of CB $CD34^+$ cells. Methods : $CD34^+$ cells were purified from CB by magnetic bead selection. The levels of of interleukin-3, interleukin-$1{\beta}$, interleukin-6, granulocyte macrophagecolony stimulating factor and tumor necrosis factor-${\alpha}$ were measured in culture supernatants on 0, 1, 2, and 3 weeks, using ELISA techniques. CB $CD34^+$ cells were expanded in Iscoves modified Dulbeccos medium in the presence of several cytokines. The expression of E-selectin, vascular cell adhesion molecule-1, intercellular adhesion molecule-1, platelet/endothelial cell adhesion molecule-1, von Willebrand factor, vimentin, and CD14 in newly developed stromal cells was examined by immunocytochemical method. Relevant extracellular matrix (ECM) proteins and proper cytokines were also assayed for the most suitable condition for expansion of stromal cells. Results: Several cytokines were found to have been produced by CB $CD34^+$ cells as well as bone marrow-derived $CD34^+$ cells. During ex vivo expansion of CB $CD34^+$ cells, stromal cells appeared in the culture by day 4 and expanded over the following 7-10 days before being confluent by day 2 1. These cells expressed surface markers characteristic of cells of endothelial lineage. Furthermore, these stroaml cells also expanded effectively when treated with thrombopoietin+flt-3 ligand+stem cell factor+leukemia inhibitory factor or 0.1% poly-L-lysine-coated wells. Conclusion: Stromal cells were developed during ex vivo expansion of CB $CD34^+$ cells and that this development could be enhanced further by treating the stromal cells with cytokines or ECM.

Purpose: Obesity is associated with metabolic dysregulation, but the underlying metabolic signatures involving clinical and inflammatory profiles of obese asthma are largely unexplored. We aimed at identifying the metabolic signatures of obese asthma. Methods: Eligible subjects with obese (n = 11) and lean (n = 22) asthma underwent body composition and clinical assessment, sputum induction, and blood sampling. Sputum supernatant was assessed for interleukin $(IL)-1{\beta}$, -4, -5, -6, -13, and tumor necrosis factor $(TNF)-{\alpha}$, and serum was detected for leptin, adiponectin and C-reactive protein. Untargeted gas chromatography time-of-flight mass spectrometry (GC-TOF-MS)-based metabolic profiles in sputum, serum and peripheral blood monocular cells (PBMCs) were analyzed by orthogonal projections to latent structures-discriminate analysis (OPLS-DA) and pathway topology enrichment analysis. The differential metabolites were further validated by correlation analysis with body composition, and clinical and inflammatory profiles. Results: Body composition, asthma control, and the levels of $IL-1{\beta}$, -4, -13, leptin and adiponectin in obese asthmatics were significantly different from those in lean asthmatics. OPLS-DA analysis revealed 28 differential metabolites that distinguished obese from lean asthmatic subjects. The validation analysis identified 18 potential metabolic signatures (11 in sputum, 4 in serum and 2 in PBMCs) of obese asthmatics. Pathway topology enrichment analysis revealed that cyanoamino acid metabolism, caffeine metabolism, alanine, aspartate and glutamate metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, pentose phosphate pathway in sputum, and glyoxylate and dicarboxylate metabolism, glycerolipid metabolism and pentose phosphate pathway in serum are suggested to be significant pathways related to obese asthma. Conclusions: GC-TOF-MS-based metabolomics indicates obese asthma is characterized by a metabolic profile different from lean asthma. The potential metabolic signatures indicated novel immune-metabolic mechanisms in obese asthma with providing more phenotypic and therapeutic implications, which needs further replication and validation.

Objectives : The objective of this study was to evaluate the gastric protective effect of Curcuma Longae Rhizoma (CLR) in 150 mM HCl/60% ethanol induced gastric ulcer (GU) in mice. Methods : Forty ICR mice were divided into five groups (n=8/Group): Nor group; Normal, Veh group; GU control, SC group; GU + sucralfate 10 mg/kg, CL; GU + CLR 30% ethanol extract 100 mg/kg, CH group; GU + CLR 30% ethanol extract 200 mg/kg. Then, mice were orally administered with 150 mM HCl/60% ethanol and caused GU. After 1 hr, mice were sacrificed, and blood and stomach tissue were collected. Results : CLR showed significance scavenging effects in 1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) radical scavenging activities (DPPH IC₅₀; 78.18 ± 0.60 ㎍/㎖, ABTS IC₅₀; 55.91 ± 1.86 ㎍/㎖). CLR significance reduce inflammatory-related factors such as cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β), and interleukin-6 (IL-6) via nuclear factor kappa B (NF-κB) inactivation. In addition, the activation of nuclear factor erythroid2-related factor 2 (Nrf2) significantly led to up-regulation of anti-oxidant enzymes including factors heme oxygenase-1 (HO-1), super oxide dismutase (SOD), and glutathione peroxidase-1/2 (GPx-1/2). Conclusions : Our discovery provides that CLR possesses anti-oxidant and anti-inflammatory effects. Hence, CLR may ameliorate the development of gastric ulcer though the inhibition of NF-κB inflammatory pathway and the elevation of Nrf2 anti-oxidant pathway.
