Objectives: We aimed to identify the dose-dependent inhibitory effects of Yukmijihwang-tang-Hap-Sabaek-san(YMHSB) and Root cortex of Morus alba L.(RCM) on the mRNA expression of Interieukin(IL)-6, IL-S, granulocyte macrophage colony stimulating factor(GM-CSF) involved in the asthma model. Methods: In this study BEAS-2B cell lines, human epithelial cells, were used. These cells were stimulated by tumor necrosis $factor(TNF)-{\alpha},\;IL-1{\beta}$ and histamine for artificial inflammatory expression. ${\beta}-actin$ messenger RNA(mRNA) was used for the internal standard. After each 24 hours of the YMHSB and RCM treatment, total cellular RNAs were collected by treating RNA zol directly on the living cells. Then the transcriptional activities of IL-6, 8 and GM-CSF were measured by RT-PCR with electrophoresis. Results: In the YMHSB study, the mRNA expression of GM-CSF and IL-8 is significantly inhibited compared to that of control group. But the mRNA expression of IL-6 is not significantly inhibited. In the RCM study, the mRNA expression of GM-CSF and IL-S is significantly inhibited compared to that of control group. But the mRNA expression of IL-6 is not significantly inhibited. Conclusions: This study shows that YMHSB and RCM have dose-dependent inhibitory effects on the mRNA expression of IL-S and GMCSF in human epithelial cells. So these herbal medicines may inhibit the inflammatory process of asthma. Advanced studies are required to investigate the mechanisms of inhibition by herbal medicine in the asthma model.

In this study, a functional study was conducted to confirm the inhibitory effect of IL-6 and TFN-α, which are allergic inflammation inhibitory effects, using natural extracts 640 types of substances. Of the 640 types, 36 substances showed 100% cell viability, and among the extracts showing the IL-6 inhibitory effect, 8 substances showed an inhibitory effect similar to that of cyclosporin A, and 5 substances showed an inhibitory effect on TFN-α. In particular, two types of extracts showing a common inhibitory effect on IL-6 and TFN-α showed an anti-allergic anti-inflammatory effect and a strong anti-allergic anti-inflammatory effect in Hagocho and Snow lotus extract. It is thought that these contents can be used as a functional natural cosmetic material for allergy-inflammation suppression using natural extracts.

To elucidate the mechanism of age-related development in FGS/NgaKIST mice with spontaneous glomerulosclerotic lesion, we examined expression and localization of various cytokine mRNA in the kidney in the progression of diseases. This mouse model is the first to develop spontanously occuring glomerosclerotic lesion in the kidney. In this study, we detected the up-regulation of local cytokine genes such as IL-1$\beta$, IL-2, IL-6, IL-10, TNF-$\alpha$, TGF-$\beta$, and IFN- $\gamma$ in the kidneys. In RT-PCR and Southern blot analysis, we detected gradual expressions of cytokine mRNA of IL-1$\beta$, IL-2, IL-6, IFN- $\gamma$, and TNF $\alpha$ mRNA during the course of disease. Other cytokines including IL -10 and TGF -$\beta$ were found to be appeared the slightly expressed level at 3 to 12 weeks before onset of inflammatory lesion but they are highly expressed at the end-stage of the disease accompaning high proteinurea and wasting. In situ RT-PCR, each cytokine mRNA were specifically localized in a variety of cells including mesangial, endothelial, parietal epithelial, tubular epithelial, arterial muscle cell, and infiltrated inflammatory cells. In addition, TNF - $\alpha$was detected moderately in the visceral and parietal epithelial cell, but weakly in endothelial and mesangial cells, whereas IL-1 $\beta$ and IL -6 were strong in mesangial regions. IL-6 and TNF- $\alpha$ was highly localized in the damaged proximal and collecting tubules. Especially, TGF -$\beta$ mRNA was highly found in mesangial cells within glomerulus and interstitium during the end-stage of this disease.. These results indicate that pro inflammatory cytokines such as IL-1 $\beta$, IL-2, IL-6, and TNF- $\alpha$ were gradually expressed from the early stage of this disease to the end-stage, and that IL-10 and TGF-$\beta$ may be important in the accumulation of extracellular matrix(ECM) within glomerulus and periglomerular fibrosis in the progression of this disease as well as tissue destruction in end-stage of this disease.

Objective : Allergic Inflammation is related with secretion of Cytokine. This study was performed to examine the effects of Woobangja on anti-allergic inflammation. Method : While macrophage 264.7cells was chosen as a normal group a control group was classified into three groups. One was stimulated with LPS. and another was pretreated with Woobangja for 1 hour. The third was pretreated with gydrocortisone for 1 hour. After the pretreatment, macrophage were incubated with lipopolysaccharide(LPS) 100 ng/ml for 12h and media collected and $TNF-{\alpha}$, IL-6, $IL-1{\beta}$, IL-10 concentration in supernatants were measured each by Enzyme linked immuno-sorbent assay. Woobangja were used $50\;{\mu}g/ml$, $100\;{\mu}g/ml$, $250\;{\mu}g/ml$, $500\;{\mu}g/ml$, 1 mg/ml. Hydrocortisones were used respectively $10^{-8}\;M$,$10^{-7}\;M$,$10^{-6}\;M$,$10^{-5}\;M$,$10^{-4}\;M$. Results : Woobangja showed inhibitory effect on $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. The inhibitory effect was most significant in 1mg/ml(p<0.01), and has increased according to the number of doses. Woobangja also showed inhibitory effect on IL-10 by LPS-stimulated macrophasg 264.7. The inhibitory effect was most significant in $100\;{\mu}g/ml$, and was not in a dose-dependent manner as Hydrocortisone group. Woobangja and Hydrocortison showed contrary effect on $IL-1{\beta}$ in al five concentration(p<0.01), and at the lowest concentration ($50\;{\mu}g/ml$) the level of $IL-1{\beta}$ was the lowest. On the other hand hydrocortison was observed to have inhibitory effect on $IL-1{\beta}$ in all five concentration(p<0.01). IL-6 was inhibited by hydrocortison in a roughly dose-dependent manner, but was not inhibited by Woobangja. On the contrary Woobangja obviously increased the expression of $IL-1{\beta}$ in all five concentration(p<0.01), but it was not related with concentrations. Conclusion : 1. Woobangja does significantly inhibit the expression of $TNF-{\alpha}$ by LPS-stimulated macrophage 264.7. 2. Woobangja does significantly increse the expression of IL-6 by LPS-stimulated macrophage 264.7. 3. Woobangja does significantly increse the expression of $IL-1{\beta}$ by LPS-stimulated macrophage 264.7. 4. Woobangja does significantly inhibit the expression of IL-10 by LPS-stimulated macrophage 264.7. 5. Woobangja is observer to have anti-allergic inflammatory effect through inhibiting inflammatory cytokine.

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.

The purposes of this study were to compare and quantify the expression of IL-6, e1stase and ${\alpha}_1-PI$ in the gingival tissues of patients with type 2 diabetes mellitus and healthy adults with chronic periodontitis. Gingival tissue samples were obtained during periodontal surgery or tooth extraction. According to the patient's systemic condition & clinical criteria of gingiva, each gingival sample was devided into three groups. Group 1 (n=8) is clinically healthy gingiva without bleeding and no evidence of bone resorption or periodontal pockets, obtained from systemically healthy 8 patients. Group 2 (n=8) is inflammed gingiva from patients with chronic periodontitis. Group 3 (n=8) is inflammed gingiva from patients with chronic periodontitis associated with type 2 diabetes. Tissue samples were prepared and analyzed by Western blotting. The quantification of IL-6, elastase and ${\alpha}_1-PI$ were performed using a densitometer and statistically analyzed by one-way ANOVA followed by Tukey test. 1. The expression levels of IL-6 showed increasing tendency in group 2 and 3, and It was highest in group 3. 2. The expression of elastase showed increasing tendency in group 2 and 3, and It was highest in group 3. 3. The expression of ${\alpha}_1-PI$ showed increasing tendency in group 3 compared to group 1. 4. The ${\alpha}_1-PI$/elastase ratio was decreased in group 2 and 3 compared to group 1, especially most decreased in group 3. 5. As IL-6 levels were increasing, elastase showed increasing tendency in group 3, and although IL-6 and elastase levels were increasing, ${\alpha}_1-PI$ level in group 3 showed slightly increasing pattern comparing to group 1. In conclusion, this study demonstrated that the expression levels of IL-6 and elastase will be inflammatory markers of periodontal inflammed tissue and DM. The ${\alpha}_1-PI$/elastase ratio also may be important measuring inflmmatory factors in the progression of periodontal inflammation associated to type 2DM.

Magnesium sulfate is widely used as a food additive and as an orally administered medication. The aim of this study was to evaluate the possible cytotoxicity of magnesium sulfate on AGS human gastric adenocarcinoma cells and gastric mucosa in mice. A trypan blue exclusion assay was used to determine the reduction in viability of AGS cells exposed to magnesium sulfate, and then effects on cell proliferation were quantified. The role of magnesium sulfate-mediated pro-inflammatory cytokine production in AGS cells was also investigated. mRNA expression for IL-$1{\beta}$, IL-6, IL-8, and TNF-${\alpha}$ was determined by RT-PCR, and secretion of these cytokines was measured by ELISA. Immunohistochemical evaluation of IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ expression was conducted in mouse gastric mucosa. Addition of 3 to 50 mM magnesium sulfate to AGS cells inhibited both cell proliferation and cell viability in a dose-dependent manner. Magnesium sulfate had little effect on production of IL-$1{\beta}$ or IL-6 but significantly inhibited production of IL-8. The animal model demonstrated that magnesium sulfate induced production of IL-$1{\beta}$, IL-6, and TNF-${\alpha}$. These preliminary data suggest that magnesium sulfate had a direct effect on the stomach and initiates cytotoxicity in moderate concentrations and time periods by inhibiting viability a nd proliferation of AGS cells and by regulating expression and/or release of pro-inflammatory cytokines.

As a prototypic Thl vs Th2 cytokine, IFN-$\gamma$ and IL-4 activate distinct STAT proteins, STAT1 and STATE, respectively. In cytokine-producing Jurkat T cells, IL-4 is effectively rescued from cell death that is induced by dexamethasone, but IFN-$\gamma$ failed to do so. Since the Ras/MAPK pathway is known to play an important role in cytokine-induced cell survival, we investigated the mechanism of T cell survival through the analysis of functional cross-talk between Ras/MAPK and distinct STAT proteins that are activated by IL-4 and IFN-$\gamma$. Although IL-4 and IFN-$\gamma$ each induced the activation of STATE and STATI. in Jurkat T cells, respectively, only IL-4 was capable of inducing MAPK. Along with tyrosine kinase inhibitors, MEK/MAPK inhibitors also caused a significant suppression of the IL-4-induced STATE activity. This suggests a positive regulation of STATE by MAPK during IL-4 signal transduction. Furthermore, transfection studies with dominant active (da) vs dominant negative (dn) Ras revealed that daRas, but not dnRas, selectively up-regulated the expression and activity of STATE with a concomitant increase in MAPK activity. These results, therefore, suggest that there is a functional cross-talk between the Ras/MAPK and Jak/STAT6 pathways, which may have a role in the IL-4-induced T cell survival.
