  • The aim of the convergence study is to evaluate anti-asthma effects of white ginseng complex extract(WGCE) on OVA-induced allergic asthma in mice. WGCE was administered at 100 mg/kg and 300 mg/kg to mice, where asthma was induced by OVA. Th2 cytokine including IL-4, IL-5 and IL-13 were measured by Luminex. Also, OVA-IgE and eosinophil were measured by haemocytometer and BALF total cells were measured microscope. Production of IL-4, IL-5, IL-13 and OVA-IgE in serum was decreased, respectively, in comparison with control. The eosinophil in whole blood decreased significantly. In addition, WGCE groups showed a decrease in the BALF total cells. These results demonstrated that WGCE decreases the Th2 cytokine and asthma factors. Therefore, we strongly suggest that WGCE could be effectively used as a therapeutic drug based on its anti asthma factors.

  • The diagnosis of atopic dermatitis (AD) includes a test that checks allergen-mediated skin reactions and a method of measuring the total IgE and allergen-specific IgE in blood. However, these test methods are performed directly on the patient, which cause some pain or discomfort. In addition, the skin response test or IgE may result in false negative in about 20% of patients. In the present study, to identify specific biomarkers, HaCaT cells were used as a human keratinocyte that make up the skin, were treated IL-4 and IL-13 for 24 hours to induce a situation similar to keratinocytes in AD patients. In the HaCaT cells, pro-inflammatory cytokine such as IL-5, IL-6, and MCP-1 were increased by IL-4 and IL-13 and skin barrier proteins was reduced by IL-4 and L-13. This results showed that a situation similar to the stratum corneum of an actual patient is induced in HaCaT cells. And then the secretions of Kallikrein (KLK) 5 and KLK7 protease were checked by enzyme-linked immunosorbent assay (ELISA). It was specifically increased by IL-4 and IL-13. This showed that AD-related protease can be detected at the protein level using keratinocytes that can be taken in a non-invasive manner and suggested the possibility of applying it to AD diagnosis.

  • For evaluating the anti-allergy activity of mushrooms, forty two mushroom extracts were studied their inhibitory activities on the IgE-mediated degranulation in rat basophilic leukemia cell line (RBL-2H3 cell). Effects of mushroom extracts on the release of interleukin-4 (IL-4) and beta-hexosaminidase, and the cell viability of the IgE-sensitized were measured. From the analysis, five mushroom extracts such as the water extract from Flammulina velutipes (Curt.:Fr.) Sing showed the suppressive activities on IL-4 release as 20%. Eight extracts including the water extract of Ganoserma lucidum showed the suppressive activities on ${\beta}$-hexosaminidase release as 20%. Almost all of the extracts stimulated the proliferation of RBL-2H3 cell. The water extracts of Flammulina velutipes and Phellinus linteus were examined against the inhibitory activity in the production of IL-4 and ${\beta}$-hexosaminidase. Additionally, the extracts from Ganoserma lucidum, Isaria japonica, Phellinus linteus and Pleurotus ostreatus inhibited dose-dependently on ${\beta}$-hexosaminidase production. In conclusion, the result suggests that the mushrooms with the potent inhibitory efficacies on the degranulation of the mast cell would be candidate resources for the anti-allergy resources, and thus need to study for their utilization.

  • Background : There have been many in vitro evidences that interleukin-4(IL-4) might be the most important cytokine inducing IgE synthesis from B-cells, and interferon-gamma(IFN-$\gamma$) might be a main cytokine antagonizing IL-4-mediated IgE synthesis. Recently some reports demonstrated that IFN-$\gamma$ might be used as a new therapeutic modality in some allergic diseases with high serum IgE level, such as atopic dermatitis or bronchial asthma. To evaluate the in vivo effect of IFN-$\gamma$ in bronchial asthma we tried a clinical study. Methods : Fifty bronchial asthmatics(serum IgE level over 200 IU/ml) who did not respond to inhaled or systemic corticosteroid treatment, and 17 healthy nonsmoking volunteers were included in this study. The CD 23 expressions of peripheral B-cells, the IL-4 activities of peripheral T-cells, the serum soluble CD23(sCD23) levels, and the superoxide anion(${O_2}^-$) generations by peripheral PMN were compared between bronchial asthmatics and normal subjects. The IL-4 activities of peripheral T-cells were analyzed by T-cell supernatant (T-sup)-induced CD23 expression from tonsil B-cells. In bronchial asthmatics the serum IgE levels and histamine $PC_{20}$ in addition to the above parameters were also compared before and after IFN-$\gamma$ treatment. IFN-$\gamma$ was administered subcutaneously with a weekly dose of 30,000 IU per kilogram of body weight for 4 weeks. Results : The ${O_2}^-$ generations by peripheral PMNs in bronchial asthmatics were higher than normal subjects($8.23{\pm}0.94$ vs $5.00{\pm}0.68\;nmol/1{\times}10^6$ cells, P<0.05), and significantly decreased after IFN-$\gamma$ treatment compared to initial values($3.69{\pm}0.88$ vs $8.61{\pm}1.53\;nmol/1{\times}10^6$ cells, P<0.05). CD23 expression of peripheral B-cells in bronchial asthmatics was higher than normal subjects($47.47{\pm}2.96%$, vs $31.62{\pm}1.92%$, P<0.05), but showed no significant change after IFN-$\gamma$ treatment. The serum sCD23 levels in bronchial asthmatics were slightly higher than normal subjects($191.04{\pm}23.3\;U/ml$ vs $162.85{\pm}4.85\;U/ml$), and 11(64.7%) of 17 patients showed a decreasing pattern in their serum sCD23 levels after IFN-$\gamma$ treatment. However the means of serum sCD23 levels were not different before and after IFN-$\gamma$ treatment. The IL-4 activities of peripheral T-cells in bronchial asthmatics were slightly higher than normal subjects($22.48{\pm}6.81%$ vs $18.90{\pm}2.43%$), and slightly increased after IFN-$\gamma$ treatment($27.90{\pm}2.56%$). Nine(60%) of 15 patients showed a decreasing pattern in their serum IgE levels after IFN-$\gamma$ treatment. And the levels of serum IgE were significantly decreased after IFN-$\gamma$ treatment compared to initial values ($658.67{\pm}120.84\;IU/ml$ vs $1394.32{\pm}314.42\;IU/ml$, P<0.05). Ten(83.3%) of 12 patients showed an improving pattern in bronchial hyperresponsiveness after IFN-$\gamma$ treatment, and the means of histamine $PC_{20}$ were significantly increased after IFN-$\gamma$ treatment compared to initial values ($1.22{\pm}0.29mg/ml$ vs $0.69{\pm}0.17mg/ml$, P<0.05). Conclusion : Our results suggest that IFN-$\gamma$ may be useful as well as safety in the treatment of bronchial asthmatics with high serum IgE level and that in vivo effects of IFN-$\gamma$ may be different from its in vitro effects on the regulations of IgE synthesis or the respiratory burst of PMN.

  • This research was carried out to evaluate the value of tofu containing mushroom as a immunomodulator. Tofu was made using $CaSO_4{\cdot}2H_2O$ or Lactobacillus extract as a coagulant after adding powder of fruit bodies or mycelia of Letino edodes and Lepista nuda to soybean milk. Proximate compositions of tofu and tofu containing mushroom were analyzed. Levels of interferon ${\gamma}$ (IFN-${\gamma}$), interleukin 4 (IL-4) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) in culture media of lymphocytes collected from mouse spleens after being injected with mushroom, regular tofu, or tofu made with mushroom were measured by sandwich ELISA. In addition, concentrations of IgG1, IgG2a and IgE in plasma or lymphocyte culture media were analyzed. Crude protein, crude lipid and crude ash were decreased in tofu containing mushroom but phosphorus was increased significantly. IFN-${\gamma}$ concentration was significantly decreased in mice injected with fruit body or tofu alone. IL-4 level was decreased significantly in mice injected with tofu containing fruit body of L. edodes. However, TNF-${\alpha}$ was increased in mice injected with tofu containing fruit body of L. edodes. Plasma levels of IgG1 were increased in almost all groups, while there was no significant change in IgG2a levels among treated mice groups. Concentrations of IgG1 and IgG2a were increased significantly in lymphocyte culture media of mice injected with tofu containing mushroom. Plasma levels of IgE level was significantly increased in mice injected with tofu or fruit body of L. edodes, but not in mice treated with tofu containing mushroom. These results showed that tofu with mushroom affected immune activities, and it seems valuable to consider developing the mixture of tofu and L. edodes as an immunomodulator.

  • This study investigated the effects of Myagropsis myagroides ethanol extract (MMEE) on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD)-like skin lesions in BALB/c mice. The effects of MMEE on DNCB-induced BALB/c mice were evaluated by examining skin symptom severity, levels of total immunoglobulin E (IgE), tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), interleukin (IL)-4, and IL-10 in serum, and levels of IL-4, IL-5, IL-13, and $interferon-{\gamma}$ ($IFN-{\gamma}$) in splenocytes. MMEE significantly reduced the total clinical severity score, total IgE levels, as well as $TNF-{\alpha}$ and IL-4 production in an AD mouse model but increased IL-10 production. Production of IL-4, IL-5, and IL-13 in splenocytes was reduced by MMEE, whereas $IFN-{\gamma}$ production increased. These results suggest that MMEE can inhibit the development of AD-like skin lesions in BALB/c mice by modulating the immune response and may be an effective potential therapeutic agent for AD.

  • This study was performed to investigate the effect of oral administration of deer horn against the asthma. Deer horn improves body metabolism and strengthens overall health, especially in elderly persons and young children. Additionally, it stimulates sexual function in females and can stimulate wound healing. Asthma was induced to Balblc mouse by i.p. injection and aerosol immunization with ovalbumin. It was observed the change of the eosinophil number in the BALF. Concentrations of IL-4, IL-5 in BALF and splenocyte were assessed by ELISA, IgG and IgE from serum were calculated by same method. The number of eosinophil in BALF was not significantly changed in deer horn group compared with control group. Concentration of IL-4 in BALF was significantly decreased in deer horn group compared with control group. Levels of IL-5 from BALF and splenocyte were significantly decreased in deer horn group compared with control group, respectively. Concentrations of IgE and IgG in serum were significantly decreased in deer horn group compared with control group, separately. We found that the effect of deer horn extract in asthma was implicated in reductions of IL-4, IL-5 released from Th2 cell, and decreases of IgG, IgE from plasma cell. These findings suggest that deer horn extract can produce anti-asthmatic effect, which may play a role in allergen-induced asthma therapy.

  • Objective : The water extract of Bojungikgi-tang (BTE) composed with Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Atractylodes Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Cimicifuga Rhizoma, and Bupleuri Radix and it has been traditionally used for chronic diseases or weakness after illness in oriental countries. However, little is known about the effects of aqueous extract of BTE on trimellitic anhydride (TMA)-induced contact hypersensitivity (CHS). Therefore, the aim of this study was to investigate the effects of BTE on TMA-induced CHS in BALB/c mice.Methods : In this study, the extract of BTE was prepared by extracting with distilled water at 100℃ for 2.5 h. The extract was freeze-dried following filtration through 0.45 μm filter. Mice were orally administrated with or without BTE extract of different doses (25-200 ㎎/㎏/day) for 28 days. During the challenge period, mice were externally applied with different doses of BTE extract one time per day 30 min before TMA treatment. I examined the effects of BTE on the serum levels of IgE, IgG1, IgG2a, and IgG2b, nitric oxide (NO) and prostaglandin E2 (PGE2) production in isolated peritoneal macrophages, Th2 cytokine production in isolated spleen cells, ear swelling responses, and the leukocyte infiltration induced by TMA.Results : The orally and externally administration of BTE dose-dependently reduced the serum levels of hapten-specific immunoglobulin E (IgE), IgG1 titer, and PGE2 production as well as ear swelling responses and leukocyte infiltration in TMA-induced BALB/c mice. The levels of NO and PGE2 production from peritoneal macrophages stimulated with TMA-BSA were markedly suppressed by pretreatment with BTE in a concentration dependent manner. Furthermore, the levels of Th2 cytokines (IL-4, IL-5, IL-13) production from spleen cells stimulated with ConA were markedly suppressed by BTE treatment in a concentration dependent manner.Conclusions : These results suggest that BTE treatment suppresses chronic contact hypersensitivity, and it can be assumed that the suppression of ear swelling, serum IgE, NO and PGE2 levels, leukocyte infiltration, and Th2 cytokines in an animal model. Therefore, these properties may contribute to the strong anti-CHS response effect of BTE.

  • Cordyceps sinensis has been clinically used for the treatment of recovering fatigue, promoting the production of body fluid and qi, resolving sputum and arresting cough. Recent studies showed that Cordyceps sinensis produced immune-modulatory, anticarcinogenic and antioxidative effects. But, there are lack of studies regarding the effects of Cordyceps sinensis on the asthma. So, this study was performed to investigate the oral administrated effects of this herb against the disease. Asthma was induced to Balb/c mouse by i.p. injection and aerosol immunization with ovalbumin, and the change of the eosinophil number in the bronchoalveolar avage fluid(BALF) was observed. Concentrations of Interleukine-4(IL-4), Interleukine-5(IL-5) in BALF and splenocyte were assessed by ELISA, ImmunoglobinG(IgG) and ImmunoglobinE(IgE) from serum were calculated by same method. We found that the effects of Cordyceps sinensis in asthma mouse was implicated in reductions of IL-4, IL-S released from type2 T helper (Th2) cell, and decreases of IgE from plasma cell. These findings suggest that Cordyceps sinensis can produce anti-asthmatic effect, which may play a role in allergen-induced asthma therapy.
