The Korean genuine medicine, 'Gigukjihwangtanggami (GJT)' has long been used clinically for hypertension and various cerebrovascular diseases. However, experimental study has been carried out very little. Recently cytokines involved in the regulation of inflammatory reactions and immune responses may play an important role in the pathogenesis of cerebral infarction (CI). The aim of this study is to investigate the effect of GJT on the production of pro-inflammatory cytokines and anti-inflammatory cytokines in peripheral blood mononuclear cells (PBMCS) stimulated with lipopolysaccaride (LPS) from Cl patients. The amount of tumor necrosis $factor-{\alpha}\;(TNF-{\alpha}),\;interleukin-1{\beta}\;(IL-1{\beta})$, IL-6, IL-8, IL-4 and IL-10 in PBMC culture supernatant was significantly increased in the LPS treated cells compared to unstimulated cells. GJT inhibited the production of $TNF-{\alpha},\;IL-1{\beta}$, IL-6 and IL-8 induced by LPS. The maximal inhibition rate of the $TNF-{\alpha},\;IL-1{\beta}$, IL-6 and IL-8 production by pretreatment of GJT (1 mg/ml) was $57.32{\pm}2.5%$ (p.0.05), $42.02{\pm}3.5%$ (p.0.05), $40.02{\pm}2.3%$ (p.0.05) and $48.02{\pm}3.1$, (p.0.05), respectively. In the Other hand, GJT increased the production of IL-4 and IL-10. The maximal increase rate of the IL-4 and IL-10 production by pretreatment of GJT (1 mg/ml) was $42.4{\pm}3.3%$ (p.0.05) End $56.4{\pm}2.9%$ (p.0.05), respectively. Taken together, these results indicate that GJT Ray have regulatory effects on the cytokine production and suggest that GJT might use clinically for the treatment of CI.

This study was designed to investigate the anti-inflammatory effect of oyster shell extract on the production of pro-inflammatory factors [NO, reactive oxygen species (ROS), nuclear factor-kappa B (NF-${\kappa}B$), inducible nitric oxide synthase (iNOS) and cycloxygenase-2 (COX-2)] and pro-inflammatory cytokines [Interleukin-$1{\beta}$ (IL-$1{\beta}$), Interleukin-6 (IL-6) and TNF-${\alpha}$] in the lipopolysaccharide (LPS)-stimulated Raw 264.7 cells. Cell viability, as measured by the MTT assay, showed that oyster shell extract had no significant cytotoxicity in Raw 264.7 cells. The treatment with oyster shell extract decreased the generation of intracellular reactive oxygen species dose dependently and increased antioxidant enzyme activities, such as SOD, catalase, GSH-px in LPS-stimulated macrophage cells. Oyster shell extract significantly suppressed the production of NO and also decreased the expressions of iNOS, COX-2 and NF-${\kappa}B$. Additionally, oyster shell extract significantly inhibited the production of IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ in LPS-stimulated Raw 264.7 cells. Thus, these results showed that the oyster shell extract had an anti-inflammatory effect on LPS-stimulated Raw 264.7 cells.

Codonopsis lanceolatae has been used as one of the traditional remedies as well as food source. However, few studies on their immunomodulating effects have been reported. We previously reported that ex vivo supplementation of Codonopsis lanceolatae water extracts enhanced splenocyte proliferation compared to the control group. In order to elucidate its ex vivo effect, six to seven week old balb/c mice were fed ad libitum on a chow diet and water extracts of Codonopsis lanceolatae were orally administrated every other day for four weeks at two different concentrations (50 and 500 mg/kg B.W). After preparing the single cell suspension, the proliferation of splenocytes was determined by MTT (3- [4,5-dimethylthiazol-2-y] -2,5-diphenyl terazolium bromide) assay. The production of cytokine (IL-1${\beta}$, IL-6, TNF-${\alpha}$), secreted by macrophages stimulated with LPS or not, was detected by ELISA assay using a cytokine kit. After 48 hrs of incubation with the mitogen (ConA or LPS) stimulation, the mice splenocyte proliferation in experimental group was statistically increased at two different concentrations than that in control group. The cytokines production was more significantly enhanced at the lower supplementation (500 mg/kg B.W.) group rather than higher concentration (500 mg/kg B.W.) compared to the control group. The results of this study may suggest that the supplementation of water extract of plant mixture could regulate the immune function by increasing the splenocyte proliferation and enhance the immune function through regulating cytokine production capacity by activated macrophages in mice.

Objective: The aim of this study was to measure the concentrations of cytokines contained in the hydrosalpingeal fluid and to evaluate the effect on the mouse embryo development with the different cytokine concentration. Methods: The hydrosalpingeal fluids (HSF) were collected during the surgery for hydrosalpinx which was confirmed by hysterosalphingogram. The cytokines in HSF including interleukin (IL)-$1{\alpha}$, IL-$1{\beta}$, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-$\alpha$, Interferon-$\gamma$ (IFN-$\gamma$), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), monocyte chemotactic protein-1 (MCP-1) were measured by ELISA method. HSF were added up to culture media with 5%, 10%, and 30% concentrations. The blastulation rates were compared. Results: IL-$\alpha$, IL-$1{\beta}$, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-$\alpha$, IFN-$\bamma$, VEGF, EGF, and MCP-1 were detected, but the concentrations were different from each sample. IL-6 and IL-10 were increased in HSF-1 group, and IFN-$\gamma$, MCP-1, VEGF were increased in HSF-2 compared with normal serum range. The Th1/Th2 ratio of HSF-2 (IFN-$\gamma$:IL10) was highly elevated to 61.64, compared with that of HSF-1 (3.69). The blastulation rate was significantly decreased in HSF-2 group (27.7%) compared those of the HSF-1 group (74%) and control group (76.7%). It showed the trend that the blastulation rate was decreased depending on the concentration HSF of culture media in HSF-2 group, but it was not statistically significant. Conclusion: The composition and concentration of cytokines in each HSF were different, and increased proinflammatory cytokines in HSF might be associated with poor embryonic development. Further study will be needed about the effect of each cytokines in HSF.

Endothelial protein C receptor (EPCR) plays a pivotal role in augmenting Protein C activation through the thrombin-thrombomodulin complex. EPCR activity is markedly changed by ectodomain cleavage and released as the soluble protein (sEPCR). EPCR shedding is mediated by tumor necrosis factor-${\alpha}$ converting enzyme (TACE). Lycopene found in tomatoes and tomato products has anti-oxidant, anti- cancer and anti-inflammatory effects. However, little is known about the effects of lycopene on EPCR shedding. We investigated this issue by monitoring the effects of lycopene on the phorbol-12-myristate 13-acetate (PMA), tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and on the cecal ligation and puncture (CLP)-mediated EPCR shedding. Data showed that lycopene potently inhibited the PMA, TNF-${\alpha}$, IL-$1{\beta}$ and CLP-induced EPCR shedding by suppressing TACE expression. Furthermore, lycopene reduced PMA-stimulated phosphorylation of p38, extracellular regulated kinases (ERK) 1/2 and c-Jun N-terminal kinase (JNK). Given these results, lycopene should be viewed as a candidate therapeutic agent for the treatment of various severe vascular inflammatory diseases via inhibition of the EPCR shedding.

Purpose: The aims of this study were to analyze the association between inflammatory cytokine and obstructive sleep apnea (OSA), and to evaluate treatment outcome and changes of plasma inflammatory cytokine levels after oral appliance therapy. Methods: Twenty-seven subjects who visited Department of Oral Medicine in Seoul National University Dental Hospital were performed nocturnal polysomnography and analyzed plasma C-reactive protein (CRP), interleukin (IL)-$1{\beta}$, IL-6, IL-10, and tumor necrosis factor (TNF)-${\alpha}$ levels. Each subject was evaluated with Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS). The subjects were classified into 12 OSA patients (apnea-hypopnea index [AHI] >5) and 15 control (AHI ${\leq}5$) groups. The OSA group was treated with mandibular advancement device (MAD) for 3 months and re-evaluated nocturnal polysomnography and plasma inflammatory cytokine levels. Results: Plasma TNF-${\alpha}$, IL-10, and IL-6 levels were significantly higher in OSA patients compared to controls. Total AHI showed significant positive correlations with plasma IL-6 and TNF-${\alpha}$ levels. Percentage time of $SpO_2$ <90 and lowest $SpO_2$ were significantly correlated with plasma TNF-${\alpha}$ level. ESS showed significant positive correlation with plasma IL-10 level. Total AHI, percentage time of $SpO_2$ <90, lowest $SpO_2$, and mean $SpO_2$ were significantly improved after the MAD therapy. Plasma TNF-${\alpha}$ level was significantly decreased after MAD therapy. Conclusions: We suggest that MAD therapy is an effective treatment modality for patients with OSA and can decrease plasma cytokine level.

The nucleotide-oligomerization domain (NOD) proteins are members of the NOD-like receptor (NLR) family, which are intracellular and cytoplasmic receptors. We analyzed the role of NODs for cytokine production by macrophages infected with intracellular pathogen M. leprae, the causative agent of leprosy. Production of pro-inflammatory cytokines such as IL-$1{\beta}$ and TNF-${\alpha}$ was inhibited in the presence of cytochalasin D, an agent blocking phagocytosis, suggesting that intracellular signaling was, partially, required for macrophage activation to M. leprae infection. Next, we investigated the role of NOD1 and NOD2 proteins on NF-${\kappa}B$ activation and cytokine expression. Treatment with M. leprae significantly increased NF-${\kappa}B$ activation and expression of TNF-${\alpha}$ and IL-$1{\beta}$ in NOD1- and NOD2-transfected cells. Interestingly, their activation and expression were inhibited by cytochalasin D, suggesting that stimulation of NOD proteins may be associated with the enhancement of cytokine production in host to M. leprae.
