Yijung-tang (YJT) is a traditional herbal formula comprising 4 medicinal herbs. In the present study, we performed the simultaneous analysis for three compounds of YJT and examined anti-allergic effects in vitro. The column for separation of three compounds was used Gemini C18 column and maintained at 40$^{\circ}C$. The mobile phase for gradient elution consisted of two solvent systems. To evaluate Th2 chemokines, YJT was treated into tumor necrosis factor (TNF)-${\alpha}$ and interferon (IFN)-${\gamma}$-stimulated HaCaT cells, and performed ELISA for thymus and activation regulated chemokine (TARC) and regulated on activation, normal T-cell expressed and secreted (RANTES). To measure Th2 cytokines, YJT was added into primary mouse splenocytes, and performed ELISA for interleukin (IL)-4, 5, 13. Calibration curves were acquired with r² >0.9999. The contents of liquiritin, glycyrrhizin, and 6-gingerol in YJT were 4.50 mg/g, 11.10 mg/g, and 1.33 mg/g, respectively. YJT inhibited production of TARC and RANTES in TNF-${\alpha}$ and IFN-${\gamma}$-treated HaCaT cells. YJT also reduced production of IL-4, 5, and 13 in primary mouse splenocytes. In conclusion, our data will be a valuable information to improve quality control and anti-allergic effects of YJT.

The feature of asthma are airway inflammation (AI), reversible airway obstruction, and an increased sensitivity to bronchoconstricting agents, elevated airway hyperresponsiveness (AHR), excess production of Th2 cytokines, and eosinophil accumulation in the lungs. This study was performed to investigate if oral administration of $Scutellaria$ $baicalensis$ Georgi water extracts (SBG) have the antiasthmatic potential for the treatment of asthma. Asthmatic HI and AHR were induced by systemic sensitization to ovalbumin (OVA) with intratracheal instillation with 0.1 mg/mL of diesel exhaust particles (DEP) suspension once a week for 10 weeks in BALB/c mice. SBG was orally administered with the concentraion of 200 mg/kg 5 days a week for 10 weeks. Long-term SBG treatment suppressed the eosinophil infiltration into airways from blood, the asthmatic AI and AHR by attenuating the production of cytokine IL-4, IL-5 and IL-13, histamine and OVA-specific IgE. Our data suggest that SBG has inhibitory effects on AI and AHR in a mouse model of asthma, may act as a potential Th2 cytokine antagonist, and may have a therapeutic effect on allergic asthma.

We investigated the effect of pycnogenol (PYC) supplementation on retarding the immune dysfunction of CS7BL/6 mice after murine AIDS (MAIDS) development. Dysfunction of T and B cell mitogenesis from primary cultured splenocytes has been observed with retrovirus infection and PYC supplementation partially recovered the dysfunction of T and B cells. There was an abnormal shift of cytokine pattern with retrovirns infection, which was designated by the decreased secretion of Th1 cytokines and increased secretion of Th2 cytokines. PYC supplementation increased IL-2 and $IFN-\gamma$ secretion and decreased IL-4, IL-6, and $TNF-\alpha$ secretion, but it was not sufficient enough to maintain the normal level of these cytokines. Hepatic vitamin E level was significantly decreased by retrovirns infection, in accordance with increased hepatic lipid peroxidation level, whereas PYC supplementation normalized the hepatic level of vitamin E and lipid peroxidation. This study suggests that PYC supplementation may partially help retard the incidence of symptoms during MAIDS.

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.

Currently asthma is considered to be an inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia, and mediated by Th lymphocytes expressing a Th 2 cytokine pattern. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objectives: We aimed to identify the effect of Haepyoijin-tang on the transcriptional activities of cytokines involved in the asthma model. Materials and Methods: RBL-2H3 cell lines were used. Cells were stimulated with DNP-IgE or Calcium inophore+PMA for maximal gene expression. After 24 hours of Haepyoijin-tang-treatment, total cellular RNAs were collected using the Trizol solution method. Then the transcriptional activities of cytokines(IL-1, 4, 5, 10, 13, $TNF-{\alpha}$) were measured by RT-PCR with electrophoresis. Results: DNP-IgE and Calcium inophore+PMA induced IL-4/IL-5 production separately peaked at 3 hours after the stimulation, but the efficacy was better in the Calcium inophore+PMA group. In the IL-4 study, sample groups of 10%, 1 %, 0.01 % Haepyoijin-tang-treatment showed 83%, 98%, 96% of transcriptional activities compared to the control group. In the IL-5 study, sample groups of 10%, 1%, 0.1 %, 0.01 % Haepyoijin-tang showed 97%, 99%, 99%, 99% of transcriptional activities compared to the control group. In other studies any result was not obtained. Conclusions: This study shows that Haepyoijin-tang has an inhibitory effect on the transcription of IL-4 and IL-5 gene expression in RBL-2H3 cell lines. Advanced studies are required to investigate the mechanisms of inhibition by herbal medicine in the asthma model.

In the present study, we investigated the effect of tyndallized HY7712 (tHY7712) on the expression of Th cell specific transcription factors and cytokines in whole-body ${\gamma}$-irradiated mice. Oral administration of tHY7712 strongly recovered the ${\gamma}$-irradiation-suppressed expression of helper T (Th) cell- and regulatory T cell-related transcription factors and cytokines, such as T-bet, Foxp3, IFN-${\gamma}$, TNF-${\alpha}$, and IL-10, and suppressed Th2 cell-associated transcription factor and cytokine GATA3 and IL-5, respectively. Furthermore, compared with the control, tHY7712 treatment also restored ${\gamma}$-irradiation-impaired natural killer and cytotoxic T cell activities against YAC-1 tumor cells to 97.8% and 98.6%, respectively.

Allergic asthma is a chronic pulmonary inflammatory disease characterized by reversible airway obstruction, hyperresponsiveness and eosinophils infiltration. Toll-like receptors (TLRs) signaling are closely associated with asthma and have emerged as a novel therapeutic target in allergic disease. The functions of TLR3 and TLR4 in allergic airway inflammation have been studied; however, the precise role of TIR-domain-containing adapter-inducing interferon-${\beta}$ (TRIF), the adaptor molecule for both TLR3 and TLR4, is not yet fully understood. To investigate this, we developed a mouse model of OVA-induced allergic airway inflammation and compared the severity of allergic airway inflammation in WT and $TRIF^-/^-$ mice. Histopathological assessment revealed that the severity of inflammation in airway inflammation in TRIF-deficient mice was comparable to that in WT mice. The total number of cells recovered from bronchoalveolar lavage fluid did not differ between WT and TRIF-deficient mice. Moreover, TRIF deficiency did not affect Th1 and Th2 cytokine production in lung tissue nor the level of serum OVA-specific IgE, $IgG_1$ and $IgG_{2c}$. These findings suggest that TRIF-mediated signaling may not be critical for the development of allergic airway inflammation.

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.
