The purpose of this study is to investigate effects of White Ginseng-Ejung-tang water extract (EJ) on production of various cytokines such as interleukin (IL)-2, IL-5, IL-6, IL-10, IL-12p70, macrophage inflammatory protein (MIP)-2, vascular endothelial growth factor (VEGF), keratinocyte-derived chemokine(KC), tumor necrosis factor (TNF)-${\alpha}$, and granulocyte macrophage colony-stimulating factor (GM-CSF) in RAW 264.7 mouse macrophages stimulated by lipopolysaccharide (LPS). Levels of cytokines were measured by High-throughput multiplex bead array cytokine assay based on xMAP (multi-analyte profiling beads) technology. EJ significantly decreased levels of IL-2, IL-12p70, IL-5, MIP-2 for 24 h incubation at the concentrations of 25, 50, and 100 ${\mu}g/mL$ in LPS-induced RAW 264.7 (P < 0.05). EJ significantly decreased levels of IL-6 at the concentrations of 50 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of IL-10 and VEGF at the concentrations of 25 and 100 ${\mu}g/mL$ (P < 0.05). EJ significantly decreased levels of KC at the concentrations of 100 ${\mu}g/mL$ (P < 0.05). EJ did not show any significant effect on TNF-${\alpha}$ and GM-CSF production. These results suggest that EJ has anti-inflammtory property related with its inhibition of IL-2, IL-5, IL-6, IL-10, IL-12p70, MIP-2, VEGF, and KC production in LPS-induced macrophages.

This study was performed to evaluate enhanced effect of fermented Galgeun tang (GGT) and Ssanghwa tang (SHT) on the anti-platelet aggregation. Platelet aggregation assay was performed In vitro using human platelet rich plasma(PRP) and In vivo using SD-rat plasma by platelet aggregometer. Pharmacodynamic parameters, $E_{max}$ and $EC_{50}$, were calculated using Winnolin. SD-rats administered 1 g/kg of oriental medicine every 12 hr for 8 days. Platelet aggregation was measured by optical method with collagen inducer (4 ${\mu}g$/ml). In In vitro anti-platelet study, $EC_{50}$ of GGT-A was lower than that of GGT-con about 79.13 ${\mu}g$/ml. And $EC_{50}$ of SHT-A and SHT-B was lower than that of SHT-con about 122.73 and 110.15 ${\mu}g$/ml, respectively. It is assumed that fermented GGT and SHT were more effective than original medicine. In multiple administration study, anti-platelet effect was significantly increased both GGT and SHT. Fermented GGT and SHT were more effective than original herbal medicine on anti-platelet aggregation.

Multiple lines of study have shown that Acanthopanax species have anti-oxidant and chemopreventive effect. However, the suitability of Acanthopanax sessilifloru fruit (Ogaza) as a functional food source remains to be investigated. Therefore, we have investigated the effect of Ogaza as an anti-oxidant and anti-inflammatory substance. The phenolic content of Ogaza is 56.1${\pm}$5.2 mg gallic acid equivalents (GAE) per 1 g of Ogaza. The 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid (ABTS) radical scavenging effects of Ogaza extract at 0.25, 0.5, 1, or 2 mg/mL were 34.0, 73.0, 194.3, or 339.7 $\mu g$/mL vitamin C equivalent antioxidnat capacity (VCEAC), respectively. Ogaza extract (1 or 2 mg/mL) inhibited LPS-induced TNF-$\alpha$ production (decrease of 22${\pm}$2% or 19${\pm}$6%, respectively). It also inhibited LPS-induced IL-6 production (decrease of 18${\pm}$2% or 24${\pm}$3%, respectively). In addition, Ogaza extract (0.25, 0.5, 1, or 2 mg/mL) inhibited COX-2 luciferase activity (decrease of 80${\pm}$1%, 83.${\pm}$7%, 96${\pm}$4%, or 98${\pm}$2%, respectively). Overall, these results indicated that Ogaza is promising as a functional food source due to its antioxidant and anti-inflammatory effects.

The anti-inflammatory and antioxidant activities of the Ulva lactuca Linnaeus extracts were measured. As a result of the MTT assay of the extract, it was found that the cell viabilities were higher than 90% at all concentrations, and the cell promotion rate exceeded 100% at a certain concentration. Therefore, in all subsequent experiments, the highest concentration was set at 500 ㎍/ml. In the nitric oxide (NO) assay, one of the anti-inflammatory experiments, the Ulva lactuca Linnaeus extracts exhibited inhibitory effects of 16%, 19%, and 62% at concentrations of 5, 50, and 500 ㎍/ml, respectively, compared with the LPS-only group. In tumor necrosis factor-α (TNF-α) assay, the extracts showed inhibitory effects of 16%, 17%, and 27% at concentrations of 5, 50, and 500 ㎍/ml, respectively, compared with the LPS-only group. In the interleukin-6 (IL-6) assay, the extracts also showed inhibitory effects of 15% and 28% at concentrations of 50 and 500 ㎍/ml, respectively, compared with the LPS-only group. In the total polyphenol content assay, the extracts exhibited 8.02, 9.90, and 23.8 mg GAE/g at concentrations of 0.3, 3, and 30 mg/ml, respectively. In the ABTS assay, the extracts exhibited scavenging activities of 2.6, 12.6, and 77.3% at concentrations of 0.3, 3, and 30 mg/ml, respectively. Therefore, it is considered that Ulva lactuca Linnaeus extracts can be used as anti-inflammatory and antioxidant substances for the development of functional foods.

Objective : Based on immunological mechanisms, this study examined whether subcutaneous (s.c.) injection of Clematis mandshurica Maxim. water extract (CMA) has anti-inflammatory effects, and its effect on $TNF-{\alpha}$, IL-1 and IL-10 release from synoviocytes on adjuvant arthritis (AA) in the rat. Methods : Complete Freund's adjuvant was used to induce AA in rats. Synoviocytes were separated by the method of collagenase and DNase digestion Synoviocytes proliferation was assayed by 3-(4, 5 dimethylthiazol 2 yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. $TNF-{\alpha}$, IL-1 and interleukin-10 (IL-10) production of synoviocytes was measured with ELISA. The expression of IL-10 mRNA of synoviocytes was determined using RT PCR. Results : There were significant secondary inflammatory reactions in AA rats, accompanied by the decrease of body and immune organs weight simultaneously. Synoviocytes proliferation of AA rats significantly increased, and the levels of $TNF-{\alpha}$ and IL-1 in supernatants of synoviocytes in AA rats were also elevated compared with the sham group. The administration of CMA (2, 5, 10 mg/kg, s.c.) reduced the above changes significantly. In contrast to $TNF-{\alpha}$ and IL-1, IL-10 production and the level of its mRNA of synoviocytes in AA rats apparently decreased. CMA (2, 5, 10 mg/kg, s.c.) markedly increased IL-10 in synoviocytes at protein and transcription level. Conclusion : The results indicate that CMA has a beneficial effect on rat AA due to modulating inflammatory cytokine production of synoviocytes, which play a crucial role in the pathogenesis of this disease.

CSBHT is known to improve immunological response in mice and humans. In this study, CSBHT effect was examined in the context of CD4+ T cells' survival and TCR/CD3 induced activation responses. Spleen cells from 8 week BALB/c mice were cultured in CSBHT containing medium without activation for 24, 48 hr. The MTS assay and revealed that CSBHT did not stimulate spleen lymphocytes as mitogen. Spleen lymphocytes were treated with anti-CD3e/anti-CD28 antibodies for 48hr. Flow cytometry revealed that activity of T cell decreased with CSBHT concentration. CD4+ T cells were isolated and cultured ,in CSBHT containing medium for 48 hr. CSBHT did not affect survival of sorted CD4+ T cells without any involvement of APC. In order to evaluate the direct effect of CSBHT on helper T cells's proliferative capacity prior to activation, CD4+ T cells are isolated after 24hr of culture in CSBHT containing medium and activated with and without anti-CD3e/anti-CD28 activation for 48hr. A higher level of CD69 was observed in 1 ㎍/㎖ of CSBHT treatment than control using flow cytometry. But low CD69 expression was observed in 5㎍/㎖ of CSBHT treatment. Expression of mRNA for cytokines in CD4+ T cell revealed that IL-2 expression was increased in 1 ㎍/㎖. The expression of IL-2R α, INF- γ were increased with concentration. On the other hand mRNA of IL-4 was decreased in dose dependent manner. Results suggest that CSBHT may be desirable for CD4+ T cell's activity in immune responses. Further more, CSBHT may relatively activate Th1 and inactivate Th2.

Objectives : The present study was examined to evaluate the anti-inflammatory effects of the Humulus japonicus MeOH extracts (HJE) in vivo. Methods : The effects of HJE on anti-inflammation were measured by production of NO, iNOS (inducible Nitric Oxide Synthase), COX-2, I$\kappa$B$\alpha$ (Inhibitor kappa B alpha), NF$\kappa$B (Nuclear Factor kappa B), TNF-$\alpha$ (Tumor Necrosis Factor-alpha) and IL-1$\beta$ (Interleukin-1$\beta$), IL-6 in Raw 264.7 macrophage cells stimulated with LPS. Results : 1. All concentrations of HJE(0.03 and 0.10 mg/ml) had no significant cytotoxicity in Raw 264.7 cell during the entire experimental period. 2. The level of NO and iNOS in culture medium was dramatically increased by LPS application. However, these increases were dose-dependently(0.03 and 0.10 mg/ml) attenuated by treatment with HJE. 3. HJE extract reduced PGE2 levels in a dose-dependent manner as a consequence of inhibition of COX-2 protein expression in Raw 264.7 macrophage cells stimulated with LPS. 4. 0.10 mg/ml HJE significantly inhibited the phosphorylation of I$\kappa$B$\alpha$ indicating the suppression of NF-$\kappa$B pathway in Raw 264.7 macrophage cells stimulated with LPS. 5. 0.10 mg/ml HJE significantly inhibited the production of TNF-$\alpha$ in Raw 264.7 macrophage cells stimulated with LPS. 6. All concentrations of HJE significantly inhibited the production of IL-1$\beta$, IL-6 in Raw 264.7 macrophage cells stimulated with LPS. Conclusions : These results provide evidences that therapeutic effect of HJE on heat syndrome, especially due to the acute inflammation, are partly due to the reduction of some of inflammatory factors by inhibiting iNOS and COX-2 through the suppression of p-I$\kappa$B$\alpha$. Moreover, it suggests that the mechanism of action of HJE comes from the suppression of inflammatory mediators, such as NO, PGE$_2$ and pro-inflammatory cytokines.

The present study aimed to develop new physiologically active ingredients from Angelica gigas. The polysaccharides purified from A. gigas, AGE-2c-I, showed potent anti-complementary activity in a dose-dependent manner. C₃ activation products were identified through crossed immuno-electrophoresis using anti-human C₃ antibodies and the anti-complementary activity of AGE-2c-I under Ca⁺⁺-free conditions suggests that AGE-2c-I may induce complementary activation via both alternative and classical pathways. In addition, AGE-2c-I augmented the production of various cytokines, such as interleukin (IL)-6, IL-10, IL-12, and tumor necrosis factor-α, by peritoneal macrophages. Furthermore, intravenous (i.v.) administration of AGE-2c-I dose-dependently enhanced natural killer cell cytotoxicity against YAC-1 lymphoma. In experimental lung metastasis, prophylactic i.v. administration of AGE-2c-I inhibited lung metastasis by 58% at 100 ㎍/mouse. From the above results, we suggest that AGE-2c-I purified from A. gigas has potent immune system-stimulating activities, and is a potentially promising food ingredient beneficial to human health.

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.
