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.

[Purpose] This study evaluated the anti-atopic dermatitis (AD) properties of Cordyceps militaris (CM) aqueous extract in keratinocytes in vitro and in vivo. We investigated the nutraceutical composition of the CM extract, including its protein, carbohydrate, and selected phytochemical content. [Methods] The expression of pathogenic cytokines in keratinocytes was assayed using an in vitro model. The CM extract downregulated extracellular signalregulated kinase 1/2 (ERK1/2) and p38 kinase expression in TNFα/IFNγ-stimulated HaCaT cells. We also established an in vivo AD model by repeatedly exposing the ears of mice to local Dermatophagoides farinae extract (DFE; house dust mite extract) and 2,4-dinitrochlorobenzene (DNCB). The epidermal and dermal ear thickness, mast cell infiltration, and serum immunoglobulin levels were measured following a 4-week oral administration of the CM extract. [Results] Histopathological examination showed reduced epidermal/dermal thickness and mast cell infiltration in mouse ears. The CM extract also suppressed serum immunoglobulin levels and gene expression of T helper (Th)1/Th2 cytokines in mouse ear tissue. [Conclusion] These results suggest that the CM extract may be useful for the treatment of AD-like skin lesions.

Objective : The aim of the study is to investigate the effect of electro-acupuncture (EA) on ST36 to modulate immune reaction in BALB/c mice immunized intraperitoneally with 2,4-dinitrophenylated keyhole limpet protein(DNP-KLH). Methods : Experimental mice were divided into four groups : 1) Normal group was not performed by any operation. 2) IM(Immunized) group was immunized intraperitoneally with DNP-KLH and aluminum hydroxide without electro-acupunture stimulation. 3) IM-EA(immunized-elctro- acupuncture) group was performed by successive electro-acupuncture on the ST36 acupoint after immunization. 4) IM-NA(immunized-naloxone) group was performed by immunization and electro-acupuncture with same method, but naloxone was injected intraperitoneally 30 minutes before eletro-acupuncture to inhibit the opiate receptor in spleen. Serum total immunoglobulin I(IgE) and antigen-specific IgE was measured in each group. The expression of interferon-${\gamma}$ and interleukin-4 mRNA in spleen was researched by real-time RT-PCR Results : Serum total-IgE and antigen-specific IgE were significantly decreased only in IM-EA group. The expression of interleukin-4 in spleen cell was significantly reduced not only in IM-EA group, but also in IM-EA group. Conclusions : Above results indicate that the mechanism of immunomodulatory effect of electro-acupuncture is related to opioid system especially in B-cell immune reaction. Further research on the T-cell immunity is necessary to explain the mechanism of immunomodulatory effect of electro-acupuncture.

The purpose of this study was to investigate the effect of lactic acid bacteria (LAB) cell wall extract on the proliferation and cytokine production of immune cells to select suitable probiotics for space food. Ten strains of LAB (Lactobacillus bulgaricus, L. paracasei, L. casei, L. acidophilus, L. plantarum, L. delbruekii, Lactococcus lactis, Streptococcus thermophilus, Bifidobacterium breve, and Pedicoccus pentosaceus) were sub-cultured and further cultured for 3 d to reach 7-10 Log colony-forming units (CFU)/mL prior to cell wall extractions. All LAB cell wall extracts failed to inhibit the proliferation of BALB/c mouse splenocytes or mesenteric lymphocytes. Most LAB cell wall extracts except those of L. plantarum and L. delbrueckii induced the proliferation of both immune cells at tested concentrations. In addition, the production of T_H1 cytokine (IFN-γ) rather than that of T_H2 cytokine (IL-4) was enhanced by LAB cell wall extracts. Of ten LAB extracts, four (from L. acidophilus, L. bulgaricus, L. casei, and S. thermophiles) promoted both cell proliferating and T_H1 cytokine production. These results suggested that these LAB could be used as probiotics to maintain immunity and homeostasis for astronauts in extreme space environment and for general people in normal life.

We investigated whether IFN-${\beta}$ inhibits the growth of human malignant glioma and induces glioma cell apoptosis using the human IFN-${\beta}$ gene transfected into glioma cells. A eukaryonic expression vector ($pSV2IFN{\beta}$) for IFN-${\beta}$ was transfected into the glioma cell line SHG44 using liposome transfection. Stable transfection and IFN-${\beta}$ expression were confirmed using an enzyme-linked immunosorbent assay (ELISA). Cell apoptosis was also assessed by Hoechst staining and electron microscopy. In vivo experiments were used to establish a SHG44 glioma model in nude mice. Liposomes containing the human IFN-${\beta}$ gene were injected into the SHG44 glioma of nude mice to observe glioma growth and calculate tumor size. Fas expression was evaluated using immunohistochemistry. The IFN-${\beta}$ gene was successfully transfected and expressed in the SHG44 glioma cells in vitro. A significant difference in the number of apoptotic cells was observed between transfected and non-transfected cells. Glioma growth in nude mice was inhibited in vivo, with significant induction of apoptosis. Fas expression was also elevated. The IFN-${\beta}$ gene induces apoptosis in glioma cells, possibly through upregulation of Fas. The IFN-${\beta}$ gene modulation in the Fas pathway and apoptosis in glioma cells may be important for the treatment of gliomas.

The present study evaluates the immunomodulatory effect of Bifidobacterium longum KACC 91563 in murine primary splenocytes and macrophages. B. longum KACC 91563 regulated T- and B-cell proliferation and inhibited the Th1 (IL-2, IFN-γ)/Th2 (IL-4, IL-10) cytokine imbalance and immune cytokine production. Moreover, immunoglobulin E (IgE) levels were significantly lower after treatment with B. longum KACC 91563. These findings suggest that B. longum KACC 91563 could modulate the systemic immune system toward both IgE production and regulation of the Th1/Th2 balance.

This study was carried out to investigate the comparison of immunomodualtory effects of water-extracted Ginseng Radix(GR), Pilose Asia-bell(PA), Astragali Radix(AR), Astractylodes Rhizoma alba(AA) and Dioscoreae Rhizoma (DR). The parameter examined to assess apparent immunomodulatory effect of the water-extracted GR, PA, AR, AA and DR included the regulation of Nitric oxide (NO), the expression of Th1/Th2 type cytokine, the change of B cell phenotype. The water-extracted GR, PA, AR, AA and DR inhibited NO production and iNOS protein expression in LPS stimulated RAW 264.7 macrophage cells. In the Th1 and Th2 cytokine expression, the water-extracted GR, PA, AR, AA and DR induced IL-2 and IFNr mRNA gene expression. Therefore, it seems that the water-extracted GR, PA, AR, AA and DR have a inducing effect of Th1 type cytokines. In the Flow cytometry analysis, the water-extracted GR, PA, AR, AA and DR did not change B cell phenotype (CD45R/B220). The water-extracted GR, PA, AR, AA and DR have a reducing effect of immune suppression cause by Methotrexate (MTX), an agent of immune suppression. These results suggest that the immunomodulatory effects of the water-extracted GR, PA, AR, AA and DR may be, in part, associated with the inducing IL-2 and IFNr mRNA gene expression in and regulation of NO production in macrophage cells.

Programmed cell death was characterized in the silkworm thoracic ganglia TG1, TG2 and TG3 during postembryonic periods by TUNEL assay. Apoptotic cells were detected in the three TGs of all larval stages except for day-1, 2 1st instar larvae, in which no apoptotic cells were found. From day-7 5th larva, the numbers of apoptotic cells were dramatically increased and peaked on day-1 pupa and day-2 pupa and then abruptly decreased. Apoptotic cells finally disappeared in day-1 adult. In-vivo injection of 20-hydroxyecdysone (20E) into day-8 5th larva resulted in a striking decrease of apoptotic cells. Actinomycin D (Act D) or cycloheximide (CHX), injected into hemolymph of day-8 5th larva, resulted in a decrease of apoptotic cells in the three TGs. Injection of caspase-8 and -3 inhibitors also blocked cellular apoptosis. These results will provide valuable information for understanding of cellular changes in the three TGs during metamorphosis of the insect species.
