  • The present experiments were designed to study the influence of Baekgumhwan on immune function of ICR mice under stress condition. Baekgumhwan was orally administered to the mice for 15days. on the 11th day the mice subjected to electric footshock for 5days(2 session a day, 11 footshocks a 31 min-session). B/T cell populations in splenocytes were studied by FACS analysis and cytokines($IFN-{\gamma}$ rand IL-10) production of the mouse splenocytes treated with PHA were studied by sandwich ELISA assay on the 15th day. The results were as follows. 1. After electric footshock, mice became sluggish and crowded to one side of the cage. Increased B/T cell populations in splenocytes were observed. These results confirm that electric footshock caused stress inducing immunological and behavioral changes in ICR mice. 2. Baekgumhwan administration without stress increase B cell populations in splenocytes, but T cell populations and cytokines($IFN-{\gamma}$ and IL-10) production of the mouse splenocytes treated with PHA maintain as similar levels as in the normal group. 3. Baekgumhwan administration with stress significantly antagonized the effect of electric footshock on behavior, increased B cell populations in splenocytes, so maintain as similar levels as in the normal group. cytokines($IFN-{\gamma}$ rand IL-10) production of the mouse splenocytes treated with PHA maintain as similar levels as in the normal group and T cell populations in splenocytes were increased as stress control.

  • Objective: In vitro fertilization (IVF) is a well-known method for the treatment of infertility. The present study aimed to compare the differences between infertile women with successful and unsuccessful IVF outcomes regarding the expression of T helper (Th) cell transcription factors and a group of related cytokines before and after exposure to their husbands' seminal plasma. Methods: This study was performed on 19 couples with unexplained infertility undergoing IVF treatment. Among the studied group, nine and 10 couples had successful and unsuccessful IVF outcomes, respectively. This study was carried out using real-time polymerase chain reaction. Results: Before seminal plasma exposure, the expression levels of T-bet (p< 0.007), $interferon-{\gamma}$ (p= 0.013), and tumor necrosis factor $(TNF)-{\alpha}$ (p= 0.017) were higher in the infertile women with IVF failure than in those with successful IVF outcomes, while those of GATA3 (p< 0.001), Foxp3 (p= 0.001), and interleukin (IL)-35 (p< 0.003) were lower. After seminal exposure, the expression of T-bet (p= 0.02), Rorc (p< 0.001), $TNF-{\alpha}$ (p= 0.001), Foxp3 (p= 0.02), and $interferon-{\gamma}$ (p= 0.001) increased in the unsuccessful IVF group, while the expression of Foxp3 (p= 0.02), Rorc (p< 0.001), IL-23 (p= 0.04), IL-17 (p= 0.02), IL-6 (p< 0.001), transforming growth $factor-{\beta}$ (p= 0.01), and IL-35 (p< 0.001) increased in the successful IVF group. Conclusion: In summary, IVF failure was associated with imbalanced Th1/Th2/Th17/Treg responses. Moreover, our results show that seminal plasma might have a positive effect on IVF outcomes via changes in peripheral blood T cell subsets.

  • Objective : This Experimental study was done to investigate the Effect of Taklisodok-um and Hwangryunhaedok-tang(TH) on Atopic Dermatitis. Methods : We assessed effects of TH on the IgE, IL-4, IL-5, IL-6, IgM, IgG1, IFN-${\gamma}$ in vivo, on the IL-4, IL-5, CCR3 in the skin tissues of ear and dorsum with NC/Nga mice. And we assessed effects of TH on the COX-2, IL-$1{\beta}$, TNF-${\alpha}$, IL-6 with RAW 264.7 cell. Results and Conclusion : 1. IgE, IL-4, IL-5, IL-6, IgM, IgGl levels in the serum of TH treated NC/Nga mouse group were decreased compared to the untreated control mice. IFN-r showed a increase in the experimental group compared to the untreated control group. The spleen weight of TH treated NC/Nga mice was decreased compared to the untreated control group. 2. mRNA expression levels of IL-4, IL-5 and CCR3 in the skin tissues of TH treated NC/Nga mice were decreased, and expression levels of IL-6 in the skin tissues of TH treated NC/Nga mice were decreased compared to the untreated control group. IFN-${\gamma}$ mRNA expression levels were increased compared to the untreated control group. 3. Judged from that IL-$1{\beta}$, TNF-${\alpha}$, IL-6 express of gene, effect of inflammatory Cytokines revelation were decreased compared to the untreated control group. 4. Depend on the strength of TH, inflammatory RAW 264.7 in the serum of TH were inhibited compared to the untreated control serum that leaded a COX-2 activity model. 5. Histological observation of the ear and skin tissues showed that the extents of inflammation and infiltrated immune cells in the epidermis and dermis of TH treated NC/Nga mice were highly reduced compared to the untreated control group.

  • The immunomodulatory effect of a new herbal preparation, HemoHIM, on the recovery from leukopenia induced by cyclophosphamide treatment was investigated. The HemoHIM was made up with an addition of the ethanol-insoluble fraction to the total water extract of Angelica Radix, Cnidii Rhizoma and Paeonia Radix. Daily oral administration of 100 mg/kg BW or 500 mg/kg BW HemoHIM accelerated the recovery from cyclophosphamide-induced leukopenia. HemoHIM increased the number of leukocytes and lymphocytes in the peripheral blood when compared with the cyclophosphamide-treated control. Moreover, the suppressed natural killer (NK) cell activity and interferon $(IFN)-{\gamma}$ secretion in the cyclophosphamide-treated mice were restored by the administration of HemoHIM. HemoHIM significantly reduced the abnormally heightened ratio of interleukin $(IL)-4/IFN-{\gamma}$ and immunoglobulin (Ig)E/IgG2a in the cyclophosphamide-treated mice. These results suggest that HemoHIM accelerates the recovery from leukopenia and alleviates the imbalanced T helper (Th)l/Th2 responses in the cyclophosphamide-treated mice. Additionally, HemoHIM was found to stimulate normal splenocytes to secrete not only Thl type cytokines such as $IFN-{\gamma}$ and IL-2, but also Th2 type cytokine IL-4. In conclusion, our results show that HemoHIM certainly has an influence on the balanced recovery of immune cells and the activation of their activities in the cyclophosphamide-treated mice.

  • Background: Allergic inflammation was induced by activated Th2 lymphocytes, leading to IgE production and eosinophil activation. A Th2 disproportion was shown in atopic children soon after birth. During specific allergen stimulation, an increase of Th2 cells was observed in most cases. In this study, we prepared new screening "whole blood" system for searching the anti-atopic materials. Cytokine production and IgE secretion from whole blood system were assessed and we confirmed the results by using animal system. Methods: Pathological features in NC/Nga mice are similar to those observed in human atopic dermatitis. Whole blood from NC/Nga mouse was stimulated by using TNCB (Th2 activator) or candidate materials of anti-atopic dermatitis, and the production of cytokines (IL-4, IL-12, and IFN-${\gamma}$) were measured by ELISA. In order to confirm the results of whole blood system, in vivo test was done by using NC/Nga mice. Results: In whole blood system, LPS and extracts of green tea, hardy orange and onion induced the production of IL-12 and IFN-${\gamma}$ while they reduced the production of IL-4. Also, LPS and extracts of onion reduced IgE production. Though atopic dermatitis was observed from a mouse stimulated with TNCB, it was not when a mouse was co-stimulated in LPS or extracts of onion. The results are same as those observed in whole blood system. Conclusion: Whole blood system was simple and speedy methods for searching a materials compared with the conventional high-cost animal system. And the results using whole blood system was proved to be reliable in our experiments for screening anti-atopic material. We expect that the system can be applied to other experiments for searching similar materials.

  • 목 적: 난관수종액내의 사이토카인 농도를 측정하고, 사이토카인 농도가 다른 난관수종액을 이용하여 생쥐 배아 발생에 미치는 영향을 비교하고자 하였다. 연구방법: 난관수종액은 자궁난관 조영술에서 난관수종이 진단되어 복강경을 통한 난관 절제술을 시행하는 경우 난관 절제술 전에 난관으로부터 채취한 다음 3,000 rpm에서 10분간 원심분리시킨 후 상층액만을 $-20^{\circ}C$에서 보관하였다. 난관수종액의 사이토카인의 조성 및 농도를 확인하기 위하여 interleukin (IL)-$1{\alpha}$, IL-$1{\beta}$, IL-2, IL-4, IL-6, IL-8, IL-10, tumor necrosis factor (TNF)-$\alpha$, interferon (IFN)-$\gamma$, vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), monocyte chemotactic protein (MCP)-1 등을 ELISA 방법으로 측정하였다. 기본 배양액에 난관수종액을 5%, 10%, 30%의 비율로 첨가하여 각 군별로 배반포로의 발달을 관찰하였다. 결 과: 난관수종액내에서 IL-$1{\alpha}$, IL-$1{\beta}$, IL-2, IL-4, IL-6, IL-8, IL-10, TNF-$\alpha$, IFN-$\gamma$, VEGF, EGF, MCP-1가 검출되었으며, 그 농도에 있어서는 큰 차이를 보였다. 정상 혈청 농도에 비하여 난관수종액-1은 IL-6, IL-10이 증가되어 있었고, 난관 수종액-2는 IFN-$\gamma$, MCP-1 및 VEGF가 증가되어 있었다. 각 난관수종액의 Th1/Th2 비는 HSF-1의 경우 IFN-$\gamma$:IL-10이 3.69로 정상인 데 비하여 HSF-2의 경우 IFN-$\gamma$:IL-10이 61.14로 크게 증가되어 있었다. 난관수종액을 포함하지 않는 배양액에서는 배반포기 발달률은 76.7%이었고, 난관수종액-1군은 74%로 대조군과 차이를 보이지 않았지만, 난관수종액-2군의 경우 27.7%로서 대조군 및 난관수종액-1군과도 유의한 차이를 보였다. 난관수종액-1의 경우 난관수종액 농도에 따른 차이는 없었으며, 난관수종액-2군의 경우 농도에 증가함에 따라 배반포로의 발달이 감소하기는 하였지만 통계적으로 유의하지는 않았다. 결 론: 난관수종액마다 사이토카인의 조성이 다르며 이에 따라 생쥐 배아발달에 미치는 영향이 다를 수 있다. 염증성 사이토카인이 증가된 난관수종액이 배아발달에 악영향을 미칠 것으로 추정된다. 특정 사이토카인에 의한 작용을 규명하기는 위해서는 향후 지속적인 연구가 필요할 것으로 생각된다.

  • Objectives: Gagamyanggyeoksan (G-YGS) has been used to suppress allergic reaction, however, the cellular target of G-YGS and its mode of action remain unclear. The present study was designed to investigate the effect of extracted G-YGS on the PMA and lonomycin (PI)-induced activation of RBL-2H3. Methods: For this investigation, We examined IL-4, IL-13 mRNA expression by Real-Time PCR, IL-4, IL-13 production by ELISA analysis and manifestations of GATA-1, GATA-2, NF-AT1, NF-AT2, AP-1 and NF-${\kappa}B$ p65 transcription factors by western blotting, OVA-specific IgE, IL-4, IL-13 by mouse be sensitive to OVA. Results: Here we showed that treatment of RBL-2H3 mast cells with G-YGS, suppressed PI-induced production of Th2 cytokines including IL-4 and IL-13 in a dose dependent manner. The mRNA expression of IL-4 were completely abolished by G-YGS at the concentration of $100{\mu}g/ml$. Data from a stable cell lines consistently expressing IL-4. And the mRNA expression of IL-13 were abolished by G-YGS at the $200{\mu}g/ml$. But there is no difference between the $50{\mu}g/ml$, the $100{\mu}g/ml$ and the comparison. Results from the western blot analysis of transcription factors involving IL-4 and IL-13 expression indicated that it prominently decreased the expression of mast cell specific transcricption factors including GATA-1, GATA-2, NF-AT2, c-Jun, NF-${\kappa}B$ p65 but not c-Fos. And G-YGS suppressed IgE, IL-4, IL-13 in mouse be sensitive to OVA. Conclusions We suggested the anti-allergic activities of G-YGS might be mediated by down-regulation of Th2 cytokines such as IL-4 and IL-13 through the regulation of transcription factors as GATA-1, GATA-2, NF-AT2, c-Jun, NF-${\kappa}B$ p65.

  • This study was to evaluate the effect of Bulhwangeumjeonggi-san (BS) on mouse Th1 and Th2 cells' differentiation and ovalbumin (OVA)-induced allergic inflammation. The proliferation of mouse CD4 T cells and the secretion of Th1/Th2 cytokines under the influence of BS extract were measured as well as the amount ${\beta}$-hexosaminidase in RBL-wH3 cells and the levels of TNF-${\alpha}$ and IL-6 secretion in Raw264.7 cells. BALB/c mice were orally administered with BS extract and simultaneously inoculated with OVA to induce allergic reaction and measure the level of total lgE, OVA-specific lgE and the production of IFN- g, IL-4, IL-5 by the spleen cells. When mouse CD4- T cell were stimulated with anti-CD3 and anti-CD28 for 48 hours in various concentrations of BS extract, it increased proliferation of CD4 cells by 14% in 50 ${\mu}g/m{\ell}$ concentration but it showed an inhibition in higher concentrations. CD4 T cells under Th1/Th2 polarizing conditions for 3 days with BS resulted in mild decrease of IFN- g in Th1 cells and mild increase of IL-4 in Th2 cell at 50 ${\mu}g/m{\ell}$ but the level of IL-4 decreased by 18% at 100 ${\mu}g/m{\ell}$. BS extract had a dose-dependent inhibitory effect on antigen-induced release of ${\beta}$-hexosaminidase in RBL-2H3 cells. Treatment of BS extract on LPS stimulated Raw 264.7 cells showed dose-dependent decrease in TNF-${\alpha}$ production. Oral administration of BS extract on OVA-induced allergic mice showed an inhibitory effect on the levels of total serum lgE and OVA-specific lgE by 50% and 55%, respectively. Culture of spleen cells with OVA resulted in significant increase of IFN- g by 25% and significant decrease of IL-4 and IL-5 by 53%, and 38%, respectively. The results show that BS does not strongly induce mouse T cells to transform into Th1 or Th2 but it has an anti-allergic effect in vitro, and that it also corrects the unbalance between the reactions of Th cells in allergic diseases.

  • Background: Polysaccharides are the most important functional constituent in Astragalus membranaceus. The purpose of the present study was to evaluate the effect of polysaccharides isolated from the aboveground parts of A. membranaceus (AMA) and polysaccharides isolated from the roots of A. membranaceus (AMR) immune function by modulated cytotoxic T cell and Th1- and Th2-related cytokines kinetics. Methods and Results: Sprague-Dawley rats were randomly divided into exhaustive exercise case groups and non-exercise case, AMA and AMR samples were administered orally for 30 days (500 mg/kg/day and 10 mg/kg/day, respectively) and were compared to those rats in the groups fed commercial sports drink (SPD) and vehicle. Both exhaustive exercise groups and non-exercise groups had a lower ratio of $CD4^+$ and $CD8^+$ cells in the spleens of the rat fed AMA and AMR compared to those in the rats fed SPD and vehicle group. These results suggested that AMA and AMR promote an increase in the proportion of cytotoxic T cells. The IL-4-producing T lymphocytes decreased significantly in the AMR (10 mg/kg/day) group compared to SPD and vehicle, whereas the AMA group increased the IL-4 concentration more than the SPD and vehicle in exhaustive exercise group. However, the populations of IFN-${\gamma}$-producing T lymphocytes of AMR and AMA increased. AMA decreased the concentration of IFN-${\gamma}$ to inhibit the Th1 response and thereby increased the concentration of IL-4 to induce a Th2 response that was related to humoral immunity in the non-exercise group. Conclusions: These results showed that, in addition to Th1/Th2 regulation, AMR and AMA played an important immuno-modulatory role after exhaustive exercise-induced Th1/Th2 lymphocyte imbalance, which might be correlated with cytokine producing immunoregulatory cells.
