  • The present study was designed to explore the antioxidant effect of Bamboo powder and its immunoreactivity in pigs. We investigated the functional properties of Bamboo extracts by means of measuring the contents of total polyphenols and flavonoid as well as determining ABST, DPPH radical scavenging activity, and hydroxyl radical scavenging activity and anticancer activity. The total phenolic compound and flavonoids contents of Bamboo extracts were 171.25 mg/g and 127.5 mg/g, respectively. The DPPH radical, hydroxyl radical, ABST radical scavenging activity of Bamboo extracts were 17.3%, 12.5% and 21.5%, respectively. Evidenced by MTT and cell cycle assay, Bamboo dose-dependently inhibited the cell proliferation and induced G0/G1-phase arrest in CHO cells at concentrations of 100, 250, and 500 ${\mu}g/ml$ Bamboo extracts. More than 80% of apoptotic cells were observed by staining with annexin V in 500 ${\mu}g/ml$ Bamboo-treated CHO cells, indicating that Bamboo had potent anticancer activities. Next, to investigate the effect of Bamboo on cytokine, immunoglobulin concentration, and blood compositions, flatting pigs were fed with Bamboo powder for 38 days. Flatting pigs were divided into 4 groups; basal diet (control), basal diet supplemented with 1% Bamboo powder (T1), 2% Bamboo powder (T2), and 3% Bamboo powder (T3). The level of hemoglobin increased in the all Bamboo-fed groups compared with the normal control group. In particular, platelet levels in the all Bamboo-treated groups increased by approximately 90% compared with the levels from pig on a normal control. Serum levels of immunoglobulins (IgG, IgA) in the pigs fed Bamboo powder were modestly increased, and the interferon-${\gamma}$ level also was strongly increased in 2% or 3% Bamboo-fed groups compared with the levels in control groups. Together, these results demonstrated that Bamboo extracts had an effective capacity of scavenging for ABTS, DPPH, and hydroxyl radicals and showed correlation with potent phenol and flavonoid contents, thus suggesting its antioxidant potential. Moreover, administration of Bamboo in 2~3% improved blood parameters and platelets, and especially immunity-related ones such as IgG, IgA, and interferon-${\gamma}$, leading to be potential feed additives in flatting pigs.

  • The purpose of this study was to evaluate the biological activities of extracts of ramie (Boehmeria nivea (L.) Gaud.), hereafter referred to as Bn. Bn extracts from various collecting area were extracted with methanol. Two extracts from our study, Bn-13 and -82, showed significant antioxidant properties, likely due to their ability to scavenge free radicals. In addition, Bn extracts showed stronger anti-bacterial activity against Escherichia coli (Bn-40), Stapylococcus aureus (Bn-33), and Helicobacter pylori (Bn-05). In addition, this study was conducted to evaluate the anti-inflammatory effects of Bn extracts in lipopolyssacharide (LPS)- and interferon-${\gamma}$ (IFN-${\gamma}$)-stimulated RAW 264.7 macrophages cells. Bn-37 significantly inhibited the production LPS/IFN-${\gamma}$-induced nitric oxide. The most noteworthy anti-cancer effect was found in Bn-23. Bn-08 showed inhibition of aldose reductase. This study provides basic information for the development of functional foods.

  • Sopungsan (SS) is a traditional Korean decoction used for the treatment of dermatitis. The aim of this study is to confirm whether or not SS has a preventive effect on the development of atopic dermatitis in dinitrochlorobenzene-applied Nc/Nga mice. SS was administered orally to Nc/Nga mice, which led to the remarkable suppression of the development of dermatitis, as determined by a histological examination and the serum IgE levels. Moreover, SS inhibited the production of thymus- and activation-regulated chemokine (TARC) and its mRNA expression in a keratinocyte cell line, HaCaT, which had been stimulated with tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interferon-${\gamma}$ (IFN-${\gamma}$). Activation of the nuclear factor-${\kappa}B$ (NF-${\kappa}B$) or activator protein-1 (AP-1) is one of key steps in the signaling pathways mediating induction of TARC. In this study, SS selectively suppressed NF-${\kappa}B$ activation which may be essential for TARC expression in $TNF-{\alpha}/IFN-{\gamma}$ treated keratinocytes. The inhibitory effect of SS on NF-${\kappa}B$ activation and TARC production might be associated with the anti-dermatitic effects of SS.

  • Objectives: Angelicae Dahuricae Radix (Baek-Ji in Korean, BJ) is well known to be used as a medicine for cold, headache, supraorbital pain, nasal congestion, and toothache. Little is understood about the roles of BJ in the cytokine and chemokine secretion by immune cells. This study was designed to find out the effects of BJ on the cytokine and chemokine secretion in human mast cells (HMC). Methods : We treated BJ according to consistency on HMC and measured cytokines and chemokines levels using flow cytometry CBA system. Results: In BJ treated group. the expression of interferon-inducible protein 10 (IP-l0), monocyte chemoattractant protein-1 (MCP-1), chemokine (C-X-C motif) ligand 9 (MIG), and interleukin 10 (IL-l0) levels were decreased significantly and chemokine (C-C motif) ligand 5 (RANTES), IL-8, $interferone-{\gamma}$ ($IFN-{\gamma}$), and tumor necrosis factor alpha (TNF-a) were decreased significantly. Conclusion : The results of this experiment supposed that the treatment of BJ will ameliorate the secreting levels of some chemokines or cytokines such as IP-10, MCP-1, MIG, IL-10, RANTES, IL-8, $IFN-{\gamma}$, and TNF-a.

  • In our study, the several cytokines were determined in phytohaemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMC) of Adamantiades-Behcets patients. Adamantiades-Behcets disease (ABD) is a systemic inflammatory disorder and might involve immune dysfunction. High levels of $TNF-\alpha,\;IL-1\beta$ and $IFN-{\gamma}$ indicate the activation of inflammatory reactions and immune system in ABD. Gami-Phedoc-San (GPS) is an Oriental herbal medication, which has been used in Korea for the treatment of ABD. GPS (1 mg/ ml) significantly inhibited the secretion of proinflammatory cytokines, $TNF-\alpha\;and\;IL-1\beta$, compared to absence of GPS (by $50.5{\pm}1.9%$ inhibition for $TNF-\alpha$ and $106.9{\pm}16.8%$ for $IL-1\beta$). GPS also inhibited the production of $IFN-\gamma$, immunoregulatory Th1 cytokine, by $78.4{\pm}2.8%$. The inhibitory effects of GPS on cytokine secretion showed dose-dependent manner, and the pre-treatment of 1 mg/ml GPS had better effects than immunosuppressive drug for treatment of ABD, cyclosporin A. Our results suggest that GPS treatment for ABD patients might have pharmacological activity of immune and inflammatory responses through the cytokine modulation.

  • The enhancement of immunity for atopic dermatitis with application of eicosapentaenoic acid (EPA)-loaded liposome was evaluated on NC/Nga mice. The EPA-loaded liposome was coated with thiol-chitosan. The liposomes were characterized with transmission electron microscopy (TEM), surface zeta potential & particle size analyzer (Zeta-PSA) and differential scanning calorimetry (DSC). The loading efficiency of EPA in the liposome was about 4.7%. The particle size of the EPA-Ioaded liposome was about 230 nm. The values of Immunoglobulin E (IgE), interleukin-4 (IL-4), and tumor necrosis factor-$\alpha$ (TNF-$\alpha$) were reduced significantly with application of the EPA-loaded liposome. The interferon-$\gamma$ (IFN-$\gamma$) value was increased with the application effect. It is concluded that EPA loaded liposome have immunity advancing effects in mouse model of atopic dermatitis.

  • This study is aimed to investigate the anti-inflammatory effect of Euphorbiae kansui radix methanol extract (ERE) in lipopolysaccharide(LPS)-stimulated mouse peritoneal macrophages. Peritoneal macrophages were obtained from thioglycollate-injected Balb/c mice. Cells were stimulated with LPS or LPS plus interferon-gamma (IFN-${\gamma}$) in the presence of ERE and various inflammatory markers were assayed. Finally, LPS-induced signaling molecules were measured. ERE up to $400{\mu}g/m{\ell}$, was not cytotoxic to ERE inhibited LPS/IFN-${\gamma}$-induced nitric oxide (NO), inducible NO synthase. ERE also reduced the levels of cyclooxygenase-2 and the proinflammatory cytokines such as tumor necrosis factor-${\alpha}$, interleukin(IL)-6 and IL-12. The inhibitory effect of ERE on LPS-induced $I{\kappa}B{\alpha}$ degradation was weak but phosphorylation of JNK, p38 and ERK1/2 was strongly suppressed. Our data indicated that the anti-inflammatory effect of ERE in LPS-stimulated macrophages was partly mediated by its inhibition of JNK, p38 and ERK1/2.

  • Analysis of the 5'-regulatory sequence of the caprine ${\beta}$-lactoglobulin (BLG) gene promoter revealed that two different types of activation were mediated by discrete regions, from -740 to -470 and from -205 to 109, in cultured mammary HC11 cells. Activation mediated by the proximal region was observed regardless of cell growth status. Distal activation, however, was observed only after confluent growth of the cells and was enhanced by the lactogenic hormones. This activation was accompanied by appearance of binding activity of proteins to these regions in the mammary HC11 cells. The binding motifs were broadly distributed over the upstream regulatory sequence. Comparison of the binding regions and mutation analysis suggest that a binding motif homologous to the ${\gamma}$-interferon responsive element (${\gamma}$-IRE) is responsible for transcriptional activation by hormonal induction in the mammary HC11 cells. The multiple ${\gamma}$-IRE homologous motifs seem to play a significant role in enhancing mammary cell-specific activation of the caprine BLG gene.

  • Nitric oxide (NO) is synthesized by various cells involved in inflammatory reactions and may then act on mast cells. In the present work, we attempted to clarify the role of this molecule on the proliferation of mouse bone marrow derived-mast cells (BMMC). Swiss 3T3 fibroblastsproduced nitrite ($NO_{2}$) and nitrate ($NO_{3}$) upon treatment with interferon ${\gamma}$(IFN-${\gamma}$). This formation was dependent of L-arginine and could be inhibited by the -L-arginine analogue $N^{G}$-monomethyl-L-arginine ($N^{G}$MMA). The effect of IFN-g was drastically invreased by cotreatment with tumor necrosis factor g(IFN-g). BMMC were maintained in vitro for as long as 30 days when cocultured with Swiss 3T3 fibroblasts. coculture with $N^{G}$MMA, significantly increased the number of BMMC. These results indicate that NO involves the inhibition of proliferation of BMMC when cocultured with Swiss 3T3 fibroblasts.

  • This experimental study was carried out to evaluate the effects of Acanthopanacis cortex on Cytokine-inducing and and immune response in Mice. In order to investigate the effect of Acanthopanacis cortex, the following was performed; Cytotoxicity, in vitro, the fraction of $CD4^+$, $CD8^+$, $B220^+$ in splenic cell, gene expression of IL-12(p35), IL-12(p40), IFN-${\gamma}$, and splenic cell proliferation by Acanthopanacis cortex. Analysis of cytokine gene expression was carried out by RT-PCR amplification. Amplified PCR products were electrophoresed on 1.2% agarose gel, and the analysis (Ht) was used to 1D-density program. The results were obtained as follows. Acanthpanacis cortex showed didn't have cell toxicity under $12{\mu}g/m{\ell}$ group on mouse lung fibroblast cells. In an in vitro model using mouse peripheral blood mononuclear cells (PBMCs), extract of Acanthpanacis cortex induced multiple cytokine, including interleukin-12 (p35), interleukin-12 (p40), interferon-gamma (IFN-${\gamma}$). The extract also enhanced the percentages of the $CD4^+$, and $CD8^+$ in the untreated control were $22.1{\pm}3.3$ to $38.4{\pm}2.1$, and $5.0{\pm}0.4$ to $10.7{\pm}0.3%$, respectively. From above findings, it is suggested that Acanthopanacis cortex is able to anti-cancer and activate immune response system.
