  • Objectives : The aims of this study were to exploring the therapeutic effect of Imperatae Rhizoma Extract(IRE) on Asthma. Methods : To investigate biological modulation activities of IRE, we conducted the cell-based assay whether IRE could regulate T helper 2 cells activity with EL4 T cells and mouse splenocytes, and followed animal study to conform the efficacy of their therapeutic potential on OVA-induced asthmatic mouse. Results : In cell study, IRE suppress the nuclear translocation of GATA binding protein-3 protein in phorbol 12-myristate 13-acetate/Ionomycin-stimulated EL4 T cells and Interleukine(IL)-4, IL-5 and IL-13 production in splenocytes at concentration dependent manner. In animal study, IRE-treated groups both 100mg/ml and 200mg/ml improve airway hypersensitibility reaction(AHR) response to methacholine about 30% and 40% with positive control group. Peritoneal blood analysis reveal that eosinophil number and ovalbumin-specific IgE is reduced by IRE treatment. Cell number of eosinophil is also reduced in bronchoalveolar lavage of IRE group like to peritoneal cell and real time-polymerase chain reaction data show that expression levels of IL-4, IL-5 and IL-13 were down regulated in lung tissue. Finally, histological analysis indicate that IRE protect the bronchial tissue damages through the accumulation of inflammatory cells and collagen, and these effect may be cause by interfering Th2 cells activity. Conclusions : Our data represent that IRE potentiates therapeutic activities to the allergic diseases such as asthma by regulating Th2 cells differentiation.

  • Aging is associated with distinct changes in immune cells and a decline in immune function, leading to increased susceptibility to infection and reduced responses to vaccination. Certain strains of lactic acid bacteria exert beneficial effects on the immune system. Previously, we reported that Weissella cibaria JW15 isolated from kimchi possesses immune stimulatory activity in vitro. In the present study, we further investigated whether oral administration of JW15 improves immune function in aged mice. Eighteen-month-old female mice were administered JW15 daily at low (JW15-L; $1{\times}10^8CFU/mouse$) or high dosage (JW15-H; $1{\times}10^9CFU/mouse$), or with Lactobacillus rhamnosus GG (LGG) using oral gavage. Two-month-old female mice were included as healthy young mice. After 4 weeks, the mice were euthanized and immune profiles were analyzed using whole blood and spleen. In complete blood count analysis, the numbers of white and red blood cells were significantly increased in the JW15-L group compared with those in the old mouse (OM) control group. In addition, administration of either JW15 of LGG resulted in higher numbers of splenocytes in comparison with the OM group. Furthermore, proliferative potentials were higher in all probiotic groups than OM. Cytokines such as IFN-${\gamma}$ and IL-6 were secreted at higher levels in splenocytes isolated from JW15-fed mice than in OM control mice. Similarly, mRNA expression of various cytokines was altered in the JW15 groups. Collectively, these results suggest that JW15 supplementation induces immunomodulatory effects in aged mice and indicate JW15 as a potential probiotic strain to improve immune function in aged animals.

  • In order to investigate the immunomodulational effects of Lonicerae Caulis et Folium, the author measured cytokines production(IL-10, IL-12(P35), IL12(P40), $IFN-{\gamma}$) in mice splenocytes. The results were obtained as follows : 1. The water extract of Lonicerae Caulis et Folium significantly enhanced the gene expression of IL-12(P35), IL-12(P40), but reduced the gene expression of IL-10, $IFN-{\gamma}$. 2. In water fraction and ethyl acetate fraction, the gene expression of IL-12(P35), $IFN-{\gamma}$ was significantly increased and that of IL-12(P40), IL-10 was decreased. The above results demonstrate that Lonicerae Caulis et Folium has enhancing immune activity by upregulation of these cytokines. Therefore, if we make the relationship between these cytokines(IL-10, IL-12, $IFN-{\gamma}$) besides IL-1, IL-4, IL-6, $TNF-{\alpha}$, IL-8, $TGF-{\beta}$ and so on which concerned the immunopotentiation, the immunopotentiational mechanism of Lonicerae Caulis et Folium will be shown clearly.

  • Phosphorylated dextran (P-Dex) is an acidic polysaccharide that functions as an immune adjuvant. P-Dex is known to regulate immune response by maintaining a balance between Th1 and Th2 cells in vitro, and thus may also be important in the control of allergic reactions. In the current study, we report the optimum conditions required for the efficient phosphorylation of dextran without toxicity. We found that when dextran was heated at 160${^{\circ}C}$ for 24 h in phosphate buffer (pH 5.0), the resulting P-Dex demonstrated the highest phosphorus content (6.8%). We also report that P-Dex enhances mitogenic activity in mouse splenocytes and induces expression of CD69 and CD86 on the surface of B cells and dendritic cells (DC) in vitro. Oral administration of P-Dex to ovalubmin (OVA)-immunized mice was found to reduce antigen-induced cell proliferation and suppress the expression of CD86 on Th2-inducing DC via exogenous OVA stimulation. P-Dex was also found to increase IL-10 expression in the splenocytes of treated mice. These findings suggest that oral administration of P-Dex increases immunological tolerance and improves the specificity of immunological response to specific antigens.

  • This study was performed to determine the effects of $\gamma$-irradiation on the antiallergic activity of alginate. An alginate aqueous solution was $\gamma$-irradiated at 3, 5, 7, 10, 20, and 100 kGy. First, the molecular weight (Mw) of alginate rapidly decreased as the $\gamma$-irradiation dose increased up to 20 kGy. Then, the antiallergic activity of the $\gamma$-irradiated alginate was measured. Interlukin (IL)-4 cytokine and IgE level were significantly decreased in the $\gamma$-irradiated alginate groups as compared to the control group in vitro. The mice intraperitoneally administered with the $\gamma$-irradiated alginate exhibited lower ovalbumin-specific IgE and IgG1 level in serum than the control mice. Furthermore, the $\gamma$-irradiated alginate suppressed total and ovalbumin-specific IgE secretions in the splenocytes. Increased IL-2 level was observed in the culture supernatants of the splenocytes that were obtained from the mice administerd with the $\gamma$-irradiated alginate, while IL-4 level decreased. The present study indicates that $\gamma$-irradiated alginate can suppress allergy in a mouse allergy model.

  • Background and Objective : Allergy is defined as an altered reactivity to an antigen, which can result in pathologic reactions upon subsequent exposure to that particular antigen. This study was to evaluate the effect of oriental materia medica on IL-5 secretion in the mouse spleen cell. Methods : We used the splenocytes of mouse 8 weeks after its birth, and then cultivated those into the 2 experimental groups and a control group for 48 hours. The culture media of the experimental groups were made of $1{\mu}g/ml$, $10{\mu}g/ml$ oriental materia medica, representative. And the culture media of control group was given no oriental materia medica. Then, we assayed the quantity of cytokine-expression by the sandwich ELISA. The quantities of cytokine-expression of the experimental groups were compared with that of the control group, which was standardized. These methods were used for all of the oriental materia medica treated. Results : Some oriental materia medica inhibit the secretion of IL-5 in both $1{\mu}g/ml$ and $10{\mu}g/ml$ culture media. These were Acori Rhizoma, Luffae Fasciculus Vascularis, Amomi Rotundi Fructus, Schisandrae Fructus, Biotae Semen, Clematis armandii, Dioscoreae Sativa Rhizoma, Coicis Semen, Sophorae Flos, Oroxyli Semen, Aurantii Semen, Pini Nodi Lignum. Conclusion : This study indicates that some oriental materia medica inhibit the secretion of IL-5 and are beneficial for allergic disease.

  • To evaluate the immunomodulatory activity of a water extract (KMF-WE) of Korean mistletoe (Viscum album var. coloratum) fruit, we examined its ability to induce humoral and cellular immune response against keyhole limpet hemocyanine (KLH). Immunized mice with KLH admixed with KMF-WE (KLH/KMF-WE) showed significant induction of KLH-specific antibodies compared to mice immunized with KLH alone. The assay for determining isotypes of antibodies revealed that KMFWE augmented KLH-specific-IgG1 and -IgG2a production. In vitro T lymphocyte proliferation analysis against KLH revealed that the splenocytes of mice immunized with KLH/KMF-WE showed a significantly higher proliferative ability than those from mice immunized with KLH alone. The culture supernatants of splenocytes, which were harvested from mice immunized with KLH/KMF-WE, showed higher levels of both Th-1 type (IL-2, IFN-${\gamma}$) and Th-2 type (IL-4) cytokines in response to KLH stimulation compared to those from mice immunized with KLH alone. Also, in delayed-type hypersensitivity (DTH) assay, mice immunized with KLH/KMF-WE showed a significantly higher reaction to KLH than mice treated with KLH alone. These results suggest that KMF-WE possess immunoadjuvant activity to enhance both antigen-specific humoral and cellular immune responses against protein antigens (KLH).
