Objectives : This study was carried out to understand the immunity responses and anti-oxidation effect of the Gamidaeganghwal-tang(GDT) on rheumatoid arthritis by using the THP-1 cells and the serum of CIA mice. Methods : For this purpose, GDT was orally administerd to mice with rheumatoid arthritis induced by collagen II. To investigate the immunity responses, value of cytokine and gene expression in the THP-1 cell, levels of cytokines in the serum of CIA(collagen type II induced arthritis) mice, number of immunocyte in PBMC of CIA mice were measured. Then, anti-oxidant activity, scavenging activity on DHHP(2,2-diphenyl-1-picrylhydrazyl) free radical and SOD(Superoxide dismutae)-like activity of GDT was observed. Results : 1. The levels of IL-$1{\beta}$, IL-6, IL-8, MCP-1 at 100, $50{\mu}g/m{\ell}$ of GDT were significantly reduced in the THP-1 cell. 2. The levels of TNF-${\alpha}$, COX-2 mRNA expression at 100, $50{\mu}g/m{\ell}$ of GDT and IL-$1{\beta}$, IL-6 at $100{\mu}g/m{\ell}$ of GDT were significantly reduced in the THP-1 cell line. 3. The levels of IL-6, TNF-${\alpha}$ and IL-$1{\beta}$ were significantly reduced in the serum of CIA mice. 4. The absolute number of CD3+, CD4+ and CD8+ cells were significantly induced, CD3+/CD69+, CD3+/CD49+, CD19+, B220+/CD23+ cells were significantly reduced in PBMC. 5. Scavenging activity on DPPH free radical and SOD-like activity were significantly induced in a concentration dependent manner. Conclusions : Taking all these observations, GDT considered to be effective in treating rheumatoid arthritis. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

Tetrandra is the root of Stephania tetrandra 5. Moore (family Menispermaceae), or of Aristolochia frangchi Wu (family Aristolochiaceae). It is a Differ-flavored and cold-property herb acting on the urinary bladder, kidney and spleen meridiands. Known biological effects of this herb are expelling wind to relieve pain and inducing diuresis to alleviate edema. This herb also has anti-inflammatory and anti-hypersensitivity actions. Recent studies have shown that Stephanniae Tetrandrae Radix has antimicrobial effects, namely, a protective effect on acute renal failure induce by gentamicin sulfate and a suppressive effect against clostridium perfringes. However, there is a lack of studies concerning the immunological activities of this herb. The present study was conducted to evaluate the immunological activities of Stephanniae Tetrandrae Radix on the regulatory mechanisms of cytokines and nitric oxide (NO) in Raw 264.7 cells. Cell viability was measured by MTT assay after the treatment of Stephanniae Tetrandrae Radix extract (STRE) and NO production was monitored by measuring the nitrite content in culture medium. COX-2 and iNOS were determined by immunoblot analysis, and levels of cytokine were analyzed by sandwich immunoassays. Results provided evidences that STRE inhibited the production of nitrite and nitrate (NO), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$, $interleukin-1{\beta}(IL-1{\beta})$ and interleukin-6 (IL-6) in Raw 264.7 cells activated with lipopolysaccharide (LPS). These findings showed that STRE could produce some anti-inflammatory effects which might play a role in adjunctive therapy in Gram-negative bacterial infections.

Objectives : This study was to evaluate the anti-inflammatory and anti-pruritic effects of WSY-1075 composited with Corni Fructus, Angelica gigantis Radix, Lycii Fructus, Ginseng Radix, Cervi parvum Cornu and Cinnamomi Cortex in rat peritoneal mast cells (RPMCs) and scratching mouse model. Methods : WSY-1075 was prepared by extracting with 30% ethanol. In the present study, we investigated the effect of WSY-1075 on the production of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$) and histamine in rat peritoneal mast cells (RPMCs) activated with phorbol 12-myristate 13-acetate (PMA) plus calcium ionophore A23187, and on the scratching behavior in mice treated with pruriogens. Results : WSY-1075 was not cytotoxic effect in used all concentration. PMA plus A23187 treatment significantly increased TNF-${\alpha}$, IL-$1{\beta}$ and IL-6 production compared with media control in RPMCs. However, TNF-${\alpha}$, $IL1{\beta}$ and IL-6 production increased by PMA plus A23187 treatment were significantly inhibited by WSY-1075 (200 ${\mu}g/mL$ and 400 ${\mu}g/mL$). WSY-1075 also inhibited the histamine release from RPMCs stimulated by compound 48/80, which promotes histamine release. Moreover, WSY-1075 administration had an inhibitory effects on the scratching behavior induced by pruritogen (compound 48/80, histamine, serotonin and substence P) in ICR mice. Conclusion : These results suggest that WSY-1075 administration (200 mg/kg or 400 mg/kg) has the anti-inflammatory and anti-pruritic effects on the activated rat peritoneal mast cell and mouse pruritus. WSY-1075 has a potential use as a composition of medicinal plants for treatment against inflammation- and pruritus-related disease.

To investigate the effect of sea tangle on macrophage activity in normal and diabetic states, 10week old ICR mice were fed control(C) and sea tangle(S) diet containing 5%(w/w) cellulose and 13.6%(w/w) dry sea tangle for four weeks, after which two thirds of mice(CD and SD) were made diabetic by intramuscular injection of streptozotocin(150mg/kg bw). At 4th day after diabetes was apparent by urinary glucose, one half of diabetic mice(CDM and SDM) were treated with metformin(500mg/kg bw) orally. Peritoneal macrophages obtained from 3%-thioglycollate treated mice were cultured in the presence of lipopolysaccaride from Salmonella abortus equi(10$\mu\textrm{g}$/ml) for 24 hrs and tumor necrosis factor-$\alpha$(TNF$\alpha$), interleukin-1$\beta$(1L-1$\beta$)and prostaglandin E2(PGE2) were measured in culture media. Release of IL-1$\beta$and PGE2 from macrophage were increased in normal mice by sea tangle diet and had the same tedency in diabetic mice with or without metformin treatment although not statistically significant. Release of TNF$\alpha$ tended to be reduced by diabetes but were not changed significantly by sea tangle diet. Fatty acid compositions of macrophage and liver phospholipids showed that diabetes reduced arachidonic acid/linoleic acid ratio and sea tangle diet appeared to increase contentsof polyunsaturated fatty acids.

Antiallergic and antipsoriatic effects of korean Red Ginseng (KRG, steamed root of panax ginseng C.A. Meyer, Family Araliaceae) were measured. Orally administered KRG water extract potently inhibited passive cutaneous anaphylaxis (PCA). KRG water extract also showed the potent inhibition in oxazolone-induced mouse dermatitis, and suppressed mouse ear swelling by $39\%$ at 16 days at a dose of $0.1\%$. KRG water extract reduced the levels of mRNA of cyclooxygenase (COX)-2, $IL-1\beta$, $TNF-\alpha$ and $INF-\gamma$ increased in oxazolone-applied mouse ears, however, did not inhibit that of IL-4. KRG water extract also inhibited iNOS and COX-2 mRNA expression level of RAW264.7 cell induced by lipopolysaccharide. Based on these findings, we suggest that KRG can improve atopic and contact dermatitis by the regulation of $ IL-1\beta$ and $TNF-\alpha$ produced by macrophage cells and $interferon-\gamma$ produced by Th1 cells.

Immune system can protect host attacking from a variety of microorganism and virus through innate and adaptive immunities. The innate immune system can be activated by recognition of conserved carbohydrates on the cell surface of pathogen resulting in protection, immunity regulation and inflammation. Immunostimulating and anti-tumor ${\beta}$-glucan, major cell wall component of many fungi, could be recognized as pathogen associated molecular pattern (PAMP) by C-type lectin such as pathogen recognition receptor (PRR) of host innate immunity cells. In spite of many studies of basidiomycetes ${\beta}$-glucan on immunostimulation, little is known about the precise mechanism as molecular-level. Among C-type lectins, dectin-1 was cloned and reported as a ${\beta}$-glucan receptor. In this report, we demonstrated induction of cytokine gene transcription by Ganoderma lucidum ${\beta}$-glucan in the absence or presence of lipopolysaccharide (LPS) by RT-PCR analysis. The expression of murine dectin-1 (MD-1) on RAW264.7 macrophage by RT-PCR showing both the full length, 757 bp $(MD-1{\alpha})$ and alternative spliced form, 620 bp $(MD-1{\beta})$. Both $MD-1{\alpha}$ and $MD-1{\beta}$ mRNAs were induced by ${\beta $-glucan both in the absence and presence of LPS. To explore expression of inflammatory cytokines by ${\beta}$-glucan, RAW264.7 cells were treated with ${\beta}$-glucan for 12 hours. As a result, the expressions of IL-1 IL-6, IL-l0 and $TNF-{\alpha}$ were increased by ${\beta}$-glucan treatment in a dose-dependent fashion. From these results, ${\beta}$-glucan induced transcriptions of dectin-1 and immune activating cytokine genes, indicating induction of immune allertness by expressing dectin-1 and secreting inflammatory cytokines.

Objective : Activated endothelial cells mediate the cascade of reactions in response to hypoxia for adaptation to the stress. It has been suggested that hypoxia, by itself, without reperfusion, can activate the endothelial cells and initiate complex responses. In this study, we investigated whether hypoxia-induced endothelial products alter the endothelial permeability and have a direct cytotoxic effect on nerve cells. Methods : Hypoxic condition of primary human umbilical vein endothelial cells[HUVEC] was induced by $CoCl_2$ treatment in culture medium. Cell growth was evaluated by 3,4,5-dimethyl thiazole-3,5-diphenyl tetrazolium bromide [MTT] assay Hypoxia-induced products [$IL-1{\beta},\;TGF-{\beta}1,\;IFN-{\gamma},\;TNF-{\alpha}$, IL-10, IL-6, IL-8, MCP-l and VEGF] were assessed by enzyme-linked immunosorbent assay. Endothelial permeability was evaluated by Western blotting. Results : Prolonged hypoxia caused endothelial cells to secrete IL -6, IL -8, MCP-1 and VEGF. However, the levels of IL -1, IL -10, $TNF-{\alpha},\;TGF-{\beta},\;IFN-{\gamma}$ and nitric oxide remained unchanged over 48 h hypoxia. Hypoxic exposure to endothelial cells induced the time-dependent down regulation of the expression of cadherin and catenin protein. The conditioned medium taken from hypoxic HUVECs had the cytotoxic effect selectively on neuroblastoma cells, but not on astroglioma cells. Conclusion : These results suggest the possibility that endothelial cell derived cytokines or other secreted products with the increased endothelial permeability might directly contribute to nerve cell injury followed by hypoxia.
