  • Ixeris sonchifolia Hance(Godulbaegi), Oenanthe javanica(Dolminari), Fagopyrum esculentum Moench(Buckwheat), Hizikia fusiforme(Seaweed Fusiforme) and Zingiber officinale Roscoe(Ginger) have all been used as one of the traditional remedies as well as food source. There are few studies However, on their immunomodulating effects have been reported. We previously reported that ex vivo supplementation of each of the Ish, Oj, Fem, Hf and Zor water extracts enhanced the splenocytes proliferation compared to the control group. In this study, the combined immunomodulative effects of a plant water extract mixture containing these five food sources(Ish+Oj+Fem+Hf+Zor) was compared to the individual effect of each. The production of cytokine(IL-1${\beta}$, IL-6, and TNF-${\alpha}$), secreted by macrophages stimulated with LPS or without, were detected via ELISA assay using a cytokine kit. After 48hrs of incubation with mitogen(ConA or LPS) stimulation, the mouse splenocyte proliferation in the experimental group had significantly increased at two different concentrations compared to the control group. The results of this study may suggest that the supplementing with a plant water extract mixture could regulate immune function by increasing splenocyte proliferation as well as enhance immune function by regulating the cytokine production capacity activated macrophages in mice.

  • This study was conducted to investigate effects of fructans (chicory inulin, fructooligosaccharide and chicory inulin oligosaccharide) on blood glucose, activities of disaccharidases in small bowel and kidneys, and splenocyte proliferation in streptozotocin-induced diabetic mice. Sixty ICR male mice were divided into one normal group and four diabetic groups. Diabetes was induced by injecting streptozotocin after 2 weeks of experimental diets feeding. Experimental diets based on AIN93G diet were control diet, 6$ \%$ fructooligosaccharide (FOS) diet, 6$\%$ chicory inulin oligosaccharide (CIOS) diet, 6$\%$ chicory inulin (Cl) diet, and given for 25 days after streptozotocin injection. Plasma glucose was lower in Diabetic-Cl group as compared to Diabetic-control group. Plasma insulin level was not different among diabetic groups. Specific activities of jejunal maltase and sucrase in diabetic groups were about double as that of Normal group. Jejunal maltase activity and plasma glucose were positively correlated (r=0.643). However, specific activity of renal maltase in diabetic groups was not significantly different as compared to Normal group. Stimulation index of splenocyte proliferation by lipopolysaccharide (LPS) was significantly increased in Diabetic-CIOS as compared to Diabetic-control. Stimulation index of splenocyte proliferation by Concanavalin A (ConA) tended to be higher in Diabetic-CIOS group. Concentrations of interleukin-2 and interferon- $\gamma$ secreted from splenocytes induced by ConA were not significantly different among all groups. In conclusion, fructans may be effective for lowering plasma glucose, possibly by lowering disaccharidase activity and for increasing immune responses in diabetic con-ditions, where their effects can be different depending on degree of polymerization.

  • These experiments were conducted to investigate the effects of glycyrrhizin(GL) and glycyrrhetinic acid(GA) on histamine synthesis, lymphocyte blastogenesis in C57BL/6J mice splenocytes, IL-1 production, $Ca^{2+}$ uptake by macrophage-like P388D$_{1}$ cells and plaque forming cell assay against SRBC. Histamine contents, lymphocyte blastogenesis, IL-1 activity, $Ca^{2+}$ uptake and plaque forming cell were determined by enzyme isotope method, [sup 3/H]-thymidine incorporation, C3H/HeJ mouse thymocytes proliferation, the addition of 5 $\mu$Ci/ml $^{45}$Ca$^{2+}$ to P388D$_{1}$, cell suspension and assay to sheep red blood cell, respectively. Cytotoxicity, which was expressed as 50% mortality, was occurred by the addition of GL(10$^{-3}$M) and GA(10$^{-4}$M). Histamine production in mouse spleen cell culture was significantly increased by the addition of 0.25 $\mu\textrm{g}$/ml of Con A, after 48 hour incubation. Con A dependent T-lymphocyte proliferation was also enhanced by the addition of 0.25 .mu.g/ml of Con A. The effects of GL on histamine contents and T-lymphocyte proliferation were significantly decreased at high dose (10$^{-5}$M), while IL-1 activity was remarkably suppressed by 10$^{-8}$~10$^{-4}$M of GL. $Ca^{2+}$ uptake was not changed, but antibody production was increased by GL(10 mg/kg). GA inhibited histamine contents at 10$^{-9}$~10$^{-7}$ and depressed Con A (0.25 $\mu\textrm{g}$/ml) dependent T-lymphocyte proliferation at 10$^{-7}$~10$^{-5}$M of GA, but increased suboptimal dose (Con A 0.1 $\mu\textrm{g}$/ml) at 10$^{-9}$~10$^{-7}$M of GA. IL-1 activity was suppressed by 10$^{-8}$~10$^{-4}$M of GA and $Ca^{2+}$ uptake was enhanced by 10$^{-9}$~10$^{-6}$ of GA, but antibody production was not changed by GA. From the above results, it is suggested that GL and GA have immuno-regulatory action. GL decreased cell-mediated immune response, and increased humoral immune response at high dose. On the other hand, low dose of GA enhanced cell-mediated immune response, while high doses of GA decreased humoral immune reaction.

  • Objective : Sinapis alba L. (SA) is a korean traditional herbal medicine that is usually used to prevent or treat inflammatory diseases, such as respiratory infection and rheumatoid arthritis. However, the effects of SA supplementation in vitro on serum antibody levels, splenocyte and peritoneal macrophage immune responses have not yet been determined. In this study, we examined the effect of SA on the production of Th1/Th2 cytokines. Methods : Splenocytes were isolated from naive C57BL/6 mice. Cells were enriched for CD4+ cell populations by first staining the cells with anti-CD4 (BD PharMingen, Calif, USA). CD4+ T cells were selected on a (CS) column, and the flow-through was collected as CD4+ T cells. Isolated cells were activated by overnight incubation on 24-well plates coated with $1{\mu}g/mL$ anti-CD3, $1{\mu}g/mL$ anti-CD28 and with SA ($100{\mu}g/mL$). Primary macrophages were collected from the peritoneal cavities of mice (8-week-old female C57BL/6). The peritoneal macrophages were washed and plated with RPMI-1640 overnight for the experiments. After 48-hours cultures, samples were centrifuged at 2000 rpm for 10 minutes, and the supernatants were stored at $-80^{\circ}C$. Mouse IL-4, IFN-$\gamma$ and TNF-$\alpha$ were quantified using ELISA kits (BioSource International, Camarillo, Calif, USA) according to the manufacturer's protocols. Results : SA at 100ug/ml decreased the generation of Th1 cytokine (IFN-$\gamma$) by 0.5-fold. However, SA has no effect on Th2 (IL-4) production. Conclusions : These results suggest that SA may play an important role in the control of T-cell-mediated autoimmunity by down-regulation of Th1 cytokine (especially IFN-$\gamma$, TNF-$\alpha$). These data may contribute to the design of new immunomodulating treatments for a group of autoimmune diseases.

  • Wished to examine closely effect that SoPungDoJeokTang-KaMi (SPDJTK) medicines used to atopy dermatitis disease patient get in atopy eruption control experimentally. SPDJTK medicines controlled $CD4^+/IFN-\gamma$, and $CD4^+/CD25^+/foxp3^+$ revelation that an experiment that motive allergy immune reponse because an in vitro experiment stimulates T cells of a NC/Nga mouse same time by anti-CD40/rmIL-4, and interleukin-$1{\beta}$, IL-6, TNF-$\alpha$, and TGF-$\beta$ mRNA outturn that bear in T and B cells decreased remarkably by SPDJTK medicines. Intracellular staining of splenocytes anti-CD40/rmIL-4 plus rmIL-4 stimulated as described in a, assessed after 24 h, SPDJTK exerts a mainly immunosuppressive effect that acts at least partially through suppression of the transcription factor GATA3 expression in $CD4^+$ T cells. Atopic dermatitis (AD) usually develops in patients with an individual or family history of allergic diseases, and is characterized by chronic relapsing inflammation seen specially in childhood, association with IgE hyperproduction and precipitation by environmental factors. However, the exact etiology of AD has been unclear. To further explore the pathogenesis and treatment of AD, a suitable animal model is required. We found that skin lesions, which were clinically and histologically very similar to human AD, mite antigen-induced dermatitis on the face, neck, ears and dorsal skin of inbred NC/Nga mice. Result that Th1 cell and Th2 cell observe to be shifted by cytokine expression with $CD4^+/CD25^+/foxp3^+$ Treg cells induction by SPDJTK medicines could know that SPDJTK medicines can use usefully in allergy autoimmnune diease.

  • Objectives: Maier symptoms of allergic rhinitis are nasal obstructions, sneezing and watery rhinorrhea. When exposed to certain allergens, the IgE covered mast cells degranulate and release inflammatory mediators and cytokines which result in a local inflammatory reaction. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of allergic rhinitis. This experimental study was done to reveal the effects of the Bojungikgi-tang on the allergic rhinitis. We have studied effect of mice on OVA-induced production of IL-4, IL-5, $INF-{\gamma}$ by murine splenocytes and effect of OVA-induced Total IgE and OVA-specific IgE Meterial and Metheds: 21 BALB/c rats were divided into three groups: normal group, control group, experimental group. To induce the allergic rhinitis in control group and experimental group, rats were sentitized intraperitioneally with 0.1% ovalbumin solution 3 times at intervals of 2 weeks. Then intranasal sensitization was performed by diffusing 0.1% ovalbumin solution 3 times at intervals of 2 days for a week. After that time, rats in experimental group were oral administration treated by the Bojuogikgi-tang fer 28 days. We observed changes of IL-4, IL-5, $INF-{\gamma}$, Total IgE and OVA-specific IgE. We used independent-test statistically. Results: 1. In IL-4 study, Bojungikgi-tang treated group didn't show significant differences. 2. In IL-5 study, Bojungikgi-tang treated group shows significant differences. 3. In $INF-{\gamma}$ study, Bojungikgi-tang treated group shows significant differences. 4. In Total IgE, Bojungikgi-tang treated group shows significant differences. 5. In OVA-specific IgE, Bojungikgi-tang treated group didn't show significant differences. According to this result, Bojungikgi-tang was concluded to be effective on lowering the total IgE. Through this. Bojungikgi tang seems to reduce the symptoms of allergic rhinitis. More studies are required to know exact mechanism of Bojungikgi tang to show the anti allergenic effect.

  • Objectives The purpose of this study is to investigate the effect of KKHS on atopic dermatitis in an in-vivo experiment using an NC/Nga atopic dermatitis mouse, which has histological and clinical similarities to this condition in humans. Methods To investigate the effect of KKHS on atopic dermatitis (AD), we evaluated atopic dermatitis-like skin lesions by clinical skin index and analyzed immunological parameters in peripheral blood mononuclear cells(PBMCs), splenocytes, draining lymph node(DLN) and performed skin histology in ears and dorsal skin of atopic dermatitis of NC/Nga mouse in vivo. Results In vivo, clinical skin severity score was significantly lower in the KKHS group than in the control group. IgE, IL-6, TNF-${\alpha}$, IgM, IgG2a and IgG2b levels in serum decreased remarkably in the KKHS group than in the control group, and the level of IFN-${\gamma}$ production which is secreted from Th1 cell was increased by KKHS. After this experiment we analyzed immunological cells ($CD3^+$, $CD19^+$, $CD4^+$, $CD8^+$, $CD3^+CD69^+$, $CD4^+CD25^+$ and $CD49b^+$) by flow cytometry. It results that the total absolute number of $CD3^+$, $CD19^+$, $CD4^+$ and $CD8^+$ cells were recovered as much as normal state, and the level of $CD3^+CD69^+$ in isolated DLN and PBMCs were significantly decreased, and total absolute number of $Gr-1^+$, $CD11b^+$ and $CD3^+$ in dorsal skin of NC/Nga mouse were decreased by KKHS. We analyzed ear, DLN, and neck-back skin after biopsy and dyeing by hematoxyline/eosin(H&E), toluidine staining (mast cells marker). KKHS were very effective to the histological symptoms which are in dermal and epidermal thickening, hyperkeratosis and inflammatory cell infiltration. Ear thickness was significantly decreased compared with the control group and the size of inflammatory lymphocytes cells (ILC) and plasma cells (PC) in DLN were also decreased. Conclusions KKHS on atopic dermatitis in an in-vivo experiment using an NC/Nga atopic dermatitis mouse was very effectiveness to the atopy dermatitis treatment.

  • In the recent, increased concern has been focused on the pharmacology and clinical utility of herbal extracts and derivatives as a drug or adjunct to chemotherapy and immunotherapy. Here we investigated the role of the extract of Anethi Fructus in the expression of inflammatory mediators, surface molecule, and related receptors in vitro. In murine macrophage RAW 264.7 cells and peritoneal macrophages of C57BL/6N mice, water extract of Anethi Fructus increased the production of secretary tumor necrosis factor (TNF)-a and Nitric oxide (NO), and the expression level of CD14, LPS co-receptor and CD86, co-stimulatory molecule compared to negative natural extract ex vivo. The water extract of Anethi Fructus increased the production of interferon (IFN)-g from splenocytes. Also, water extract of Anethi Fructus increased ConA-induced cell proliferation. These results suggest that water extract of Anethi Fructus may enhance the immune response through immune modulation of macrophage and lymphocytes.

  • The natural killer (NK) cell activity of splenocytes and recycling capacity of NK cells were observed by combining the $^{51}Cr-release$ cytotoxicity assay and single cell cytotoxicity assay against YAC-1. The ICR mice were infected intranasally with Naegleria fewleri, that is a pathogenic free-living amoeba. The mice infected with $1{\times}10^5$ trophosoites showed mortality rate of 76.7% and mean survival time of 12. 9 days. The cytotoxic activity of NK cells in infected mice was significantly higher than that of non-infected mice during the period between 12 hours and day 3 after infection, and highest on day 1. The target-binding capacity of NK cells in infected mice was not different from that of non-infected ones. Maximal killing potential and maximal recycling capacity were remarkably increased in infected mice as compared with the control. The results obtained in this observation indicated that elevated NK cell activity in mice infected with N. fowieri was not due to target-binding capacity of NK cells but due to the increased activity of NK cells and increased recycling capacity of individual NK cells.

  • In this study, polysaccharides were isolated from Korean persimmon vinegar to characterize the polysaccharides existing as soluble forms within traditional Korean fermented beverages, and their immuno-stimulating activities were examined. Three successive chromatographies were used to purify the main polysaccharide in the persimmon vinegar, PV-1b-I, to homogeneity from the crude polysaccharide (PV-0). The molecular mass of PV-1b-I was estimated as 110 kDa and it contained significant proportions of mannose (46.8%), galactose (28.5%) and arabinose (19.1%). PV-1b-I strongly reacted with ${\beta}$-glucosyl Yariv reagent, suggesting the presence of an arabino-3,6-galactan moiety. PV-1b-I also induced high levels of macrophage activation and mitogenicity on murine splenocytes in vitro. The intravenous administration of PV-1b-I significantly augmented NK cytotoxicity against YAC-1 tumor cells. PV-1b-I also showed potent anticomplementary activity in a dose-dependent manner. Finally, C3 activation products were identified by crossed immunoelectrophoresis using anti-human C3 and the anti-complementary activity of PV-1b-I under $Ca^{2+}$-free conditions, suggesting that this PV-1b-I causes complementary activations via both alternative and classical pathways. From these results, one can conclude that Korean persimmon vinegar contains select polysaccharides in addition to healthy components, and these polysaccharides appear to provide immuno-stimulating activities beneficial to human health.
