  • In this study, we examined immuno-modulatory activities of crude polysaccharides from wild ginseng adventitious roots (WGAR). The crude polysaccharide (WGAR-CP) was isolated from WGAR by hot water extraction, ethanol precipitation, and dialysis. The major constituents in WGAR-CP were neutral sugar (64.77%), and uronic acid (34.32%). WGAR-CP demonstrated anti-complementary activity dose-dependently. The immuno-modulatory effects of WGAR-CP were also analyzed by measuring nitric oxide and cytokines in the supernatants of mouse peritoneal macrophages. Mouse peritoneal macrophages stimulated with WGAR-CP produced nitric oxide and various cytokines such as interleukin (IL)-6 and IL-12 in a dose-dependent manner. In conclusion, WGAR-CP may have immuno-modulatory activities by activating a complementary system and macrophages, which produces cytokines.

  • Purpose : To investigate the effects of the lavender, lemon and eucalyptus oil mixture on the atopy dermatitis skin lesions induced on NC/Nga Mice by dinitrochlorobenzene (DNCB). Material and Method : For this purpose, we fabricated the oil mixture blending three essential oils (lavender, lemon, eucalyptus : ELL) with one carrier oil (jojoba) and apply it on the atopic dermatitis skin lesions of NC/Nga Mice. Atopic dermatitis in NC/Nga Mice was induced by DNCB treatment on the dorsal skin of mice for 8 weeks. The mixture of ratio of each essential oil drop was 1 (eucalyptus) : 2 (lemon) : 2 (lavender) and this mixture was blended with jojoba oil 50ml (0.025%). The ELL-ointment was supplied for 8 weeks. We evaluated the effects of ELL on cell viability of mouse lung fibroblast, clinical skin features and severity, the level of serum Immunoglobulin (Ig) E & Ig G1, Interleukin (IL)-4, IL-13 and Interferon (IFN)-$\gamma$. Results : ELL showed safety on the cell viability of mouse lung fibroblast compared with control group. The cell viability was measured by SRB method. The effects of ELL on clinical skin features and severity in DNCB-induced dermatitis model of NC/Nga mice was significant compared with control group. EEL also showed significant effects on clinical symptom score compared with control group. Serum IgE & IgG1 level and development of atopy dermatitis skin lesions were evaluated. Serum IgE & IgG1 production was significantly down-regulated in EEL group compared with control group. ELL also down-regulated the levels of IL-4 and IL-13, and up-regulated the level of IFN-$\gamma$ compared with control group significantly. Conclusion : ELL was effective on atopy dermatitis by modulating Th2 related factors.

  • Objective : Oriental medicines have been combined oriental medical theory which based on the seven modes of emotions. Notopterygium incisum (N. incisum) and Clematis manshurica (C. manshurica) have been used as an anti-rheumatic and analgesic medicine for the treatment of rheumatism, headache, cold, etc. In this study, we evaluate the synergistic anti-inflammatory effect of N. incisum and C. manshurica. Method : To evaluate the synergistic anti-inflammatory effect of a herbal mixture N. incisum and C. manshurica, we examined the changed ear thickness in 12-O-tetradecanoyl-phorbol-13-acetate (TPA)-induced mouse ear edema model after topical application of herbal mixture. In addition, the levels of markers for inflammation, such as tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, prostaglandin $G_2$ ($PGE_2$), and nitric oxide (NO) were measured by ELISA assay and Griess reagent in lipopolysaccharide-stimulated Raw 264.7 cells. Results : Our results showed that aqueous extracts of N. incisum and C. manshurica combination significantly inhibited the mouse ear edema induced by TPA. Moreover, the aqueous extracts of N. incisum and C. manshurica combination exhibited synergistic effects in down-regulating TNF-${\alpha}$, IL-$1{\beta}$, $PGE_2$ level, but not NO. Conclusions : This study suggested that combined treatment of N. incisum and C. manshurica, based on seven methods in prescription compatibility, has a synergistic effect in down-regulating inflammatory response both in vitro and in vivo models.

  • This study aimed to investigate the anti-inflammatory activities of raw (P) and roasted (RP) Perilla frutescens Britton (perilla) seeds in RAW 264.7 macrophages and an ulcerative colitis mouse model. In lipopolysaccharide-treated RAW 264.7 cells, treatment with ethanol extract of P at the concentrations of 75 and $150{\mu}g/mL$ decreased nitric oxide (NO), interleukin-6 (IL-6), and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) levels to 48-85% of the control (p<0.01). Treatment with RP extract exhibited similar effects on NO, IL-6, and TNF-${\alpha}$, decreasing those levels to 51-84% of the control (p<0.01). In dextran sulfate sodium-treated ulcerative colitis mice, dietary treatment with 1% RP for 7 days decreased the colonic levels of prostaglandin $E_2$ and leukotriene $B_4$ to 34% and 58% of the control, respectively (p<0.05). Dietary P treatment, however, did not decrease those levels significantly. These results indicate that roasted perilla seed exerts anti-inflammatory activity both in vitro and in vivo.

  • Barley has nutritional benefits due to its high dietary fiber content; therefore, the intake of whole barley grains is recommended. However, barley is often consumed in the fermented form because of the improved texture and digestibility. The present study was designed to elucidate the intracellular signaling pathway for macrophage activation by the polysaccharide BF-CP from fermented barley. BF-CP is a neutral polysaccharide, composed of neutral sugars, including glucose (70.7%), xylose (11.4%), and arabinose (9.0%). BF-CP exhibited macrophage-stimulatory activity by inducing the production of interleukin (IL)-6, tumor necrosis factor $(TNF)-{\alpha}$, and nitric oxide in RAW 264.7 macrophages. Further, BF-CP treatment strongly increased the IL-6 and $TNF-{\alpha}$ gene expression in a concentration-dependent manner. Signal transduction experiments using immunoblotting showed that BF-CP phosphorylated mitogen-activated protein kinases (MAPKs), such as c-Jun N-terminal kinase, extracellular signal-regulated kinase, and p38, and nuclear factor $(NF)-{\kappa}B$, in RAW 264.7 cells in a concentration-dependent manner. These results suggest that BF-CP activates the macrophages via MAPK and $NF-{\kappa}B$ pathways, and also induces an increase in the production of cytokines.

  • Two experiments were conducted to compare the effects of feeding organic acids and antibiotic growth promoters in weaned pigs. In Exp. 1, 96 nursery pigs (Large White$\times$Landrace; initial weight $7.80{\pm}0.07kg$) were randomly allotted into one of four dietary treatments. Pigs in treatment 1 were fed a complex starter diet. Treatments 2 to 4 were the same as treatment 1 but supplemented with antibiotics (200 ppm chlortetracycline plus 60 ppm Lincospectin), 0.5% potassium diformate or 0.5% dry organic acid blend ACTIVATE Starter DA (ASD). During the 4-week post-weaning period, pigs fed ASD or antibiotics had better gain (p = 0.03) and feed efficiency (p = 0.04) than pigs fed the control diet. On d 14 post-weaning, pigs fed the control diet had the lowest fecal lactobacilli count among all dietary treatments (p = 0.02), whereas pigs fed ASD or antibiotics had a trend for lower fecal E. coli count compared to the control pigs (p = 0.08). Serum insulin-like growth factor-1 (IGF-1) of pigs fed ASD did not differ from pigs fed the control diet (p>0.05) at d 14 after weaning. In Exp. 2, 24 weaned pigs (Large White$\times$Long White; initial weight $5.94{\pm}0.33kg$) were allotted into four groups and housed individually. Pigs were fed a control diet or diets supplemented with antibiotics (100 ppm colistin sulfate, 50 ppm Kitasamycin plus 60 ppm Olaquindox), 0.5% or 1% ASD. All pigs were orally challenged with E. coli $K88^+$ on d 5. During d 5 to 14 after challenge, pigs fed antibiotics, 0.5% or 1% ASD had better gain (p = 0.01) and feed efficiency (p = 0.03) than pigs fed the control diet. On d 14, compared to the control pigs, pigs fed 0.5% ASD had higher lactobacilli in the duodenum and pigs fed 1% ASD and antibiotics had a trend for higher lactobacilli in the ileum (p = 0.08). Pigs fed antibiotics, 0.5% or 1% ASD diets tended to have decreased ileal E. coli count compared to those fed the control diet (p = 0.08). Serum interleukin-6 and cortisol and digesta pH values were not affected by treatment or time. These results indicate that feeding ASD can improve the growth performance of weaning pigs, mainly via modulating intestinal microflora populations without affecting gastrointestinal pH or immune indices.

  • A rise in the occurrence of allergic diseases is attributed to the dysregulated balance of type 1/type 2 immunity, where type 2 T-helper (Th2) cells predominate over type 1 T-helper (Th1) cells, leading to an abnormally increased production of IgE in response to unharmful antigens. Kimchi, a traditional Korean fermented food, is a rich source of beneficial lactic acid bacteria. In this study, we investigated the ability of Enterococcus faecium FC-K derived from kimchi to induce type I immunity in the presence of Th2 polarizing conditions in vitro and in vivo. Stimulation of mouse peritoneal macrophages with E. faecium FC-K induced the production of tumor necrosis factor alpha, interleukin (IL)-6, and IL-12. Under the in vitro Th2 conditions in which splenic T cells were activated in the presence of IL-4, E. faecium FC-K enhanced the ability of T cells to produce interferon $(IFN)-{\gamma}$. Using the ovalbumin (OVA)-induced allergy model, male BALB/c mice receiving E. faecium FC-K reduced the serum level of total IgE, but not that of OVA-specific IgE. Furthermore, the population of activated splenic B cells during OVA immunization was decreased in E. faecium FC-K-treated mice, accounting for a reduction of total IgE in the serum. Restimulating splenocytes from OVA-immunized mice with OVA ex vivo resulted in an increased production of $IFN-{\gamma}$, with no effect on IL-4, in E. faecium FC-K-treated mice. These observations provide the evidence that E. faecium FC-K can be a beneficial probiotic strain that can modulate the Th2-mediated pathologic response.

  • The immunomodulatory effects of Aureohasidium pullulans SM-2001 exopolymers containing $\beta$-1,3/1,6-glucan were evaluated in cyclophosphamide (CPA)-treated mice. To induce immunosuppression, 150 and 110 mg/kg of CPA were intraperitoneally injected 3 days and 1 day, respectively, before beginning administration of the test material. Exopolymers were delivered subcutaneously or orally, four times, in a volume of 10 ml/kg at 12-h intervals beginning 24 h after the second CPA treatment. Changes in thymus and spleen weights, splenic amounts of tumor necrosis factor (TNF)-$\alpha$, interleukin (IL)-$1{\beta}$, and IL-10, and numbers of CD3+, CD4+, CD8+, and TNF-$\alpha+$ thymus and spleen cells were monitored in CPA-treated mice. As a result of CPA treatment, dramatic decreases in the number of CD3+, CD4+, CD8+, and TNF-$\alpha+$ cells were detected in the thymus and spleen, along with decreases in thymus and spleen weights. In addition, splenic TNF-$\alpha$, IL-$1{\beta}$, and IL-10 contents were also decreased on observation with flow cytometry. However, oral and subcutaneous treatments with exopolymers effectively reduced the immunosuppressive changes induced by CPA. Therefore, it is concluded that exopolymers of A. pullulans SM-2001 can effectively prevent immunosuppression through, at least partially, the recruitment of T cells and TNF-$\alpha+$ cells or enhancement of their activity, and can provide an effective component of prevention or treatment regimens for immunosuppression related to cancer, sepsis, and high-dose chemotherapy or radiotherapy.

  • Objective : The choice of tumor antigen for dendritic cell[DC]-loading has still been an unresolved problem in the DC-based vaccine strategies against malignant gliomas that has not been found well-characterized tumor specific antigens. In this study, we compare tumor-specific T cell response induced by glioma apoptotic body[GAB]-pulsed DCs to response induced by glioma cell lysate-pulsed ones quantitatively. Methods : DCs generated in the presence of granulocyte macrophage-colony stimulating factor and interleukin[IL]-4 from peripheral blood mononuclear cells[PBMCs] of HLA-A2 positive healthy donors were cultured. Each GABs and glioma cell lysate generated from HLA-A2 positive T98G glioblastoma cells were co-incubated with DCs. $CD8^+$ T lymphocytes isolated from PBMCs of same donors were cultured in media containing IL-2 and either stimulated by GAB- or lysate-pulsed DCs three times at a weekly interval. The interferon[IFN]-${\gamma}$ concentrations of each cell culture supernate were measured by enzyme immunoassay technique. Cytolytic activity of the generated cytotoxic $CD8^+$ T cells either stimulated with GAB- or lysate-pulsed DCs was determined by a standard 4-h $^{51}Cr$-release assay. Results : IFN-${\gamma}$ production and cytolytic activity of effector T cells stimulated by GAB-pulsed DCs were significantly higher than those of T cells stimulated by lysate-pulsed ones. Conclusion : These results indicate the choice of antigen is a critical determinant in the induction of antitumor immunity against malignant glioma. Antigen preparations from GABs represent a promising alternative to glioma cell lysate in DC-based glioma vaccine strategies.

  • Objectives : The aim of present study was to evaluate the beneficial effect of Scutellariae Radix (SR) and Scutellariae Radix EtOH-heated at 200℃ (SR200) using lipopolysaccharide (LPS) treated intestine of mice.Methods : Extract of SR and SR200 were orally administrated. Their effects were compared with vehicletreated LPS and normal groups. Subsequently, we measured reactive oxygen species (ROS) and nitric oxide in the serum and western blotting in the intestine.Results : The average weight in LPS treated (Vehicle) group was lowered significantly compare to that in non-treated normal group and this weight loss in the vehicle group was effectively prevented by the administration of SR and SR200 respectively. The increased oxidative stress biomarker levels such as reactive oxygen species (ROS) and nitric oxide (NO) in the serum was markedly decreased by treated with SR200. The decreased levels of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) induced by LPS injection were significantly restored by both SR and SR200 treatment. Moreover, increased inflammatory mediators and cytokines such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) in the LPS treated vehicle mice were significantly decreased through down-regulation c-JUN through reduction of oxidative stress.Conclusions : SR and SR200 could have benefit effect through down-regulation of abnormal oxidative stress in LPS induced intestine injury mice. Moreover, The anti-inflammatory activity of SR200 extract was better than SR extract in the LPS induced intestine injury mice.
