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.

Purpose:The aim of this study is to explore the effect of the Toll-like receptor 9 (TLR9) expressed in plasmacytoid dendritic cells (pDCs) that respond to antigen to Th2 immune deviation in allergic patients. Methods:Subjects consisted of 19 allergic patients and 17 healthy volunteers. Skin prick tests and nasal provocation tests were performed for the two groups. Peripheral blood mononuclear cells (PBMCs) were collected from subjects and analyzed for the Lineage Cocktail (CD3, CD14, CD16, CD19, CD20, CD56) (-), HLA-DR (+), and CD123 (+) using flow cytometry. In addition, we analyzed TLR9 mRNA by reverse transcriptase-polymerase chain reaction. The level of $interferon-{\alpha}$ ($IFN-{\alpha}$) of the PBMCs following stimulation with the TLR9 ligand CpG-ODN 2216 was also evaluated. Results:Analyses of CD123 (+) revealed a nearly similar distribution for the classical pDC markers in the allergic group ($0.1%{\pm}0.04%$) and in the controls ($0.25%{\pm}0.23%$). The mRNA levels of TLR9 on PBMCs were not different between the allergic group and the controls ($1.29{\pm}0.41$ vs. $1.25{\pm}0.23$, respectively). Additionally, the level of $IFN-{\alpha}$ in PBMCs exposed to stimuli of the TLR9 ligand CpG-ODN 2216 was not significantly different between the two groups ($911{\pm}829$ vs. $1,095{\pm}888pg/mL$, respectively). Conclusion:We found no evidence that TLR9-dependent immune responses in human pDCs are associated with allergic status.

Objective : The present experiments were designed to study on the immune-enhancing effect of Mountain grown ginseng, Mountain cultivated ginseng, and Panax ginseng Method : In order to compare the immune-enhancing effect of moutain grown ginseng, moutain cultivated ginseng and Panax ginseng, the study was done through the forced swimming test (FST), measurement of T helper Th1, Th2 cytokines and fatigue related factors. Result : Moutain grown ginseng and panax ginseng decreased the immobility time in the FST compared to the control. Glucose, blood urea nitrogen (BUN), creatinine, lactate dehydrogenase (LDH) and Total-protein (T-protein) in serum were investigated. The serum achieved from ginseng administered mouse showed higher BUN, T-protein than the control. moutain grown ginseng administered group showed lower LDH than the control group. moutain grown ginseng administered mouse showed higher glucose than the control. Creatinine was same in either experimental or control group. Ginseng-induced cytokine production in human T-cell line, MOLT-4 cells and mouse peritoneal macrophages were compared. Moutain cultivated ginseng (10-4 dilution) and panax ginseng (10-3 dilution) were increased the interferon $IFN-{\gamma}$ production compared with media control (about 1.6-fold P<0.05) at 48 h. Moutain grown ginseng (10-4 dilution) was increased the $IFN-{\gamma}$ and interleukin IL-4 production compared with media control (about l.4-fold for $IFN-{\gamma}$ and 1.6-fold for IL-4 P<0.05) at 48 h. Moutain grown ginseng (10-3 dilution) and moutain cultivated ginseng (10-4 dilution) were increased the turmor necrosis factor $TNF-{\alpha}$ production compared with $rIFN-{\gamma}$ treated cells (about 1.9-fold for $TNF-{\alpha}$ P<0.05), respectively. Moutain cultivated ginseng (10-3 dilution) was increased the IL-12 production compared with $rIFN-{\gamma}$ treated cell (about 1.7-fold for IL-12 P<0.05). Conclusion : These data suggest that three different three kinds of ginseng act on immune responses in different aspects.

Menthae herba (MH) extracts exhibit anti-inflammatory effects. The purpose of this study was to determine whether the anti-inflammatory effects of MH extracts vary according to the cultivation regions. We performed a comparative analysis of MH extracts by evaluating the production of inflammatory mediators in RAW 264.7 murine macrophage cells and HaCaT human keratinocyte cells. MH extracts obtained from different cultivation regions in Korea and China significantly reduced the production of nitric oxide (NO), prostaglandin $E_2$ ($PGE_2$), and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in RAW 264.7 cells stimulated with lipopolysaccharide (LPS). No differences in these inhibitory activities were observed between MH extracts. In HaCaT cells stimulated with TNF-${\alpha}$ and interferon-${\gamma}$ (IFN-${\gamma}$), MH extracts did not inhibit the production of macrophage-derived chemokine (MDC/CCL22), but most extracts reduced the production of the regulated on activation normal T-cell expression and secreted (RANTES/CCL5). We used clustering tree analysis of the MH extracts according to the chromatographic pattern and anti-inflammatory potency of MH extracts. We observed differences in the chromatographic pattern of MH extracts but no difference in anti-inflammatory potency. Our findings suggest that MH extracts from different regions do not show any differences in their pharmacological potency in that MH extracts are used as therapeutic agents to treat inflammatory disorders.

T cell immunoglobulin mucin domain (TIM)-3 is an immunomodulatory molecule and upregulated in T cells by several cytokines. TIM-3 also influences mast cell function but its transcriptional regulation in mast cells has not been clarified. Therefore, we examined the transcript level and the promoter activity of TIM-3 in mast cells. The TIM-3 transcript level was assessed by real-time RT-PCR and promoter activity by luciferase reporter assay. TIM-3 mRNA levels were increased in HMC-1, a human mast cell line by TGF-${\beta}1$ stimulation but not by stimulation with interferon (IFN)-${\alpha}$, IFN-${\lambda}$, TNF-${\alpha}$, or IL-10. TIM-3 promoter -349~+144 bp region relative to the transcription start site was crucial for the basal and TGF-${\beta}1$-induced TIM-3 promoter activities in HMC-1 cells. TIM-3 promoter activity was increased by over-expression of Smad2 and Smad4, downstream molecules of TGF-${\beta}1$ signaling. Our results localize TIM-3 promoter activity to the region spanning -349 to ＋144 bp in resting and TGF-${\beta}1$ stimulated mast cells.

The increase in alcohol consumption level has been noticed in Korea recently. Alcohol appreciably inhibits cell mediated immunity and this may contribute to the high prevalence of serious infection such as pulmonary tuberculosis among alcoholic subjects. The present study was undertaken to examine the effect of ethanol on the cyclooxygenase metabolites of human monocyte in vitro. Monocytes were activated with 800 units of gamma interferon(IFN-${\gamma}$) for 3 days following apply of Ficool-hypaque density gradient and gelatin coated flasks for separation of monocytes. Ethanol with addition of 100mM, 300mM and 600 mM for 30 minutes to 106 monocytes with/without previous IFN-${\gamma}$ treatment caused a dose dependent decrease in the production of thromboxane B2, 6-keto-PGE1$\alpha$ and PGE2 by radioimmunoassay at 6 hours after ethanol treatment. Quite different from the findings after 6 hours there was dose dependent increase in three prostaglandins without IFN-${\gamma}$ treatment after 24 hours of incubation. With previous treatment of IFN-${\gamma}$ reduced productions of three prostaglandins at 24 hours than control is spite of ethanol stimjulation. These findings show that IFN-${\gamma}$ can inhibit alcohol induced derangement of arachidonic acid metabolism of monocytes.

The trophic factor Neuregulin-1 (NRG-1) plays a critical role in the development of the peripheral nervous system and the repair of nerve injuries. The regulation of neutrophil apoptosis by cytokine secretion from structural cells is an important process in inflammatory diseases, including asthma. This study aimed to investigate the relationship between NRG-1 and the alteration of neutrophil apoptosis by the regulation of cytokine release in the human lung epithelial BEAS-2B cells. Tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ) induce the increase in the release of interleukin (IL)-6, IL-8, and monocyte chemoattractant protein-1 (MCP-1). NRG-1 alone had no effect on the secretion of IL-6, IL-8, and MCP-1. However, co-treatment of TNF-α and IFN-γ with NRG-1 inhibited the secretion of IL-6, IL-8, and MCP-1 that had been increased by TNF-α and IFN-γ. Treatment with NRG-1 did not have a direct effect on neutrophil apoptosis. Co-treatment of TNF-α and IFN-γ with NRG-1 was not effective on suppression of neutrophil apoptosis due to TNF-α and IFN-γ. The supernatant of BEAS-2B cells after co-treatment of TNF-α and IFN-γ with NRG-1 suppressed the inhibition of neutrophil apoptosis that had been caused due to the supernatant treated with TNF-α and IFN-γ. Taken together, NRG-1 has an anti-inflammatory effect in an inflammatory milieu by the regulation of cytokine secretion and neutrophil apoptosis.

Background: Skin is an organ that protects the human body from various environmental stimuli that can induce immune system activation. Skin aging can be largely divided into two categories: physiological aging, which is caused by the a decreased physiological function of the skin and structural changes with aging, and photoaging, which is caused by the chemical stress induced by external stimuli such as ultraviolet (UV) radiation. Methods and Results: The objective of this study was to investigate the anti-wrinkle and UV protective effect of catechin-rich green tea extract (CGTE) in activated keratinocyte (HaCaT cells) and UV-induced skin damage in hairless mice. The results showed that CGTE inhibits the tumor necrosis factor-alpha interferon-gamma ($TNF-{\alpha}+IFN-{\gamma}$)-induced expression of matrix metalloproteinase (MMP)-1 in HaCaT cells. In addition, the CGTE treatment significantly reduced wrinkle formation, epidermal thickness, collagen deposition, and transepidermal water loss in dorsal skin irradiated with UVB. However, the ${\beta}$-glucosidase activity was significantly increased. The CGTE treatment inhibits mRNA expression and enzyme activity of MMP-2 and MMP-9 in the dorsal skin irradiated with UVB. Conclusions: It is expected that CGTE can be effectively used as a functional food and cosmetic ingredient to improve skin moisture retention and reduce wrinkle formation.

Codium fragile has been traditionally used in oriental medicine to treat enterobiasis, dropsy, and dysuria, and it has been shown to possess many biological properties. Atopic dermatitis (AD) is one of the types of skin inflammation and barrier disruption, which leads to chronic inflammatory skin diseases. In the current investigation, the protective effects of C. fragile extract (CFE) on anti-inflammation and skin barrier improvement were investigated. In LPS-stimulated RAW 264.7 cells, nitric oxide generation and the expression levels of interleukin (IL)-1β, IL-4, IL-6, iNOS, COX-2, and tumor necrosis factor-alpha (TNF)-α were reduced by CFE. CFE also inhibited the phosphorylation of NF-κB-p65, ERK, p-38, and JNK. Additionally, CFE showed inhibitory activity on TSLP and IL-4 expression in HaCaT cells stimulated with TNF-α/interferon- gamma (IFN-γ). Enhanced expression of factors related to skin barrier function, FLG, IVL, and LOR, was confirmed. These findings implied that CFE may be used as a therapeutic agent against AD due to its skin barrier-strengthening and anti-inflammatory activities, which are derived from natural marine products.
