The effects of Sacchromyces cerevisiae-Fermented Artemisiae Argi Folium Water extract (AFS) on Nitric oxide production from mouse macrophage Raw 264.7 cells treated with EtOH, gallic acid, Nicotine, Acetaminophen, and Acetaldehyde were investigated through this study. AFS (0, 10, 50, 100, 200, 400 ug/mL) was simultaneously treated with EtOH (100 uM), gallic acid (100 uM), Nicotine (1 mM), Acetaminophen (2 mM), and Acetaldehyde (200 uM). And Nitric oxide production from Raw 264.7 cells was measured by Griess reagent method. AFS restorated the cellular production of Nitric oxide reduced by EtOH, gallic acid, Nicotine, and Acetaminophen in Raw 264.7 cells. AFS could be supposed to have the immuno-modulating activity concerned with macrophage's production of Nitric oxide.

Polysaccharides isolated from Korean black raspberry wine were examined for their chemical properties and immuno-modulating activities. The molecular mass of RB-1b-I, the main polysaccharide in black raspberry wine, was estimated as 180 kDa and it contained a significant proportion of mannose (76.8%) and 4 different minor component sugars such as galactose (15.8%), arabinose (3.8%), glucose (2.6%) and rhamnose (1.2%). This indicated that RB-1b-I was mainly present as a mannan, which had originated from the cell walls of fermenting yeasts. On the other hand, RB-1b-I induced high levels of macrophage activation as well as mitogenicity regarding murine splenocytes in vitro. The intravenous administration of RB-1b-I significantly augmented NK cytotoxicity against YAC-1 tumor cells. RB-1b-I also showed potent anti-complementary activity in a dose-dependent manner via both alternative and classical pathways. Results indicated that Korean black raspberry wine contains peculiar polysaccharides which provide beneficial immuno-stimulating activities for human health.

Chemokine and Growth Factor are major mediumtors of immuno-inflammatory pathway. The purpose of this study is to investigate whether productions of Chemokine and Growth Factor in lipopolysaccharide (LPS)-induced mouse macrophage RAW 264.7 cells are modulated by Gallic acid (GA), which is easily founded in tannin-containing natural materials such as red wine, green tea, grape juice, and Corni Fructus. Productions of Chemokine and Growth Factor were analyzed by High-throughput Multiplex Bead based Assay with Bio-plex Suspension Array System based on $xMAP^{(R)}$ (multi-analyte profiling beads) technology. At first, cell culture supernatant was obtained after treatment with LPS and GA for 24 hour. Then, the antibody-conjugated beads were added and incubated for 30 minutes. After incubation, detection antibody was added and incubated for 30 minutes. And Strepavidin-conjugated Phycoerythrin (SAPE) was added. After incubation for 30 minutes, the level of SAPE fluorescence was analyzed on Bio-plex Suspension Array System. Based on fluorescence intensity, concentrations of Chemokine and Growth Factor were determined. The results of the experiment are as follows. GA significantly inhibited the production of interferon-inducible protein (IP)-10, keratinocyte-derived chemokine(KC), and vascular endothelial growth factor (VEGF) in LPS-induced RAW 264.7 cells at the concentration of 25, 50, 100, 200 uM (p<0.05). GA significantly inhibited the production of monocyte chemoattractant protein-1(MCP-1) and macrophage-colony stimulating factor(M-CSF) in LPS-induced RAW 264.7 cells at the concentration of 50, 100, 200 uM (p<0.05). GA diminished the production of granulocyte macrophage-colony stimulating factor (GM-CSF) in LPS-induced RAW 264.7 cells. But GA did not show the inhibitory effect on the production of leukemia inhibitory factor (LIP) and macrophage inflammatory protein (MIP)-2 in LPS-induced RAW 264.7 cells. These results suggest that GA has the immuno-modulating activity related with its inhibitory effects on the production of IP-10, KC, MCP-1, VEGF, and M-CSF in LPS-induced macrophages.

Objectives : The effect of water extract of the pilose antler of Cervus korean TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immuno-suppressive and immuno-activating Korean oriental medicine, on collagen-induced arthritis (CIA) mice model was studied. Identification of common Nokyong capable of affording protection or modulating the onset and severity of arthritis may have important human health implications. Methods : Nokyong has shown to possess anti-inflammatory and anticarcinogenic properties in experimental animals. In this study we determined the effect of DAE on collagen-induced arthritis in mice. Results : In three independent experiments mice given DAE in water exhibited significantly reduced incidence of arthritis (33% to 50%) as compared with mice given no DAE in water (84% to 100%). The arthritis index also was significantly lower in DAE-fed animals. Western blot analysis showed a marked reduction in the expression of inflammatory mediators such as cyclooxygenase 2 (Cox-2), $Interferon-{\gamma}\;(INF-{\gamma})$, and tumor necrosis factor ${\alpha}\;(TNF-{\alpha})$ in arthritic joints of DAE-fed mice. The neutral endopeptidase (NEP) activity was approximately 6-fold higher in arthritic joints of non-DAE-fed mice in comparison to nonarthritic joints of nonimmunized mice whereas it was only 2-fold higher in the arthritic joints of DAE-fed mice. Additionally, total IgG and type II collagen-specific IgG levels were lower in the arthritic joints of DAE-fed mice. Conclusion : Taken together our studies suggest that DAE may be useful in the prevention of onset and severity of arthritis.

To develop functional food material using Rhodiola dumulosa(RD), the biological activities such as antioxidation, antiproliferation in the cancer cells and immuno-activity in macrophage cells were investigated with hexane, ethylacetate, n-butanol, methanol and water fractions of RD 80% methanol extract. Hydrogen-donating activities of hexane, ethyl acetate, n-butanol, methanol and water fraction were 28.30, 53.21, 35.48, 42.64 and 21.14%, respectively, at a concentration of 100 ${\mu}g/mL$, and the activity of ethyl acetate fraction was similar to as that of BHT. After treated for 48 hrs, the ethyl acetate fraction decreased the proliferation of the A549 and SW480 cells in a dose-dependent manner at concentration of 10, 50, and 100 ${\mu}g/mL$, the activities were higher than other fractions. Morphology of cells treated with the ethyl acetate fraction for 48 hr at 100 ${\mu}g/mL$ was distorted with shrank cell mass, and the cell number was lower than that of control cells the macrophage cells treated. The methanol fraction was significantly induced NO production compared with untreated control cells at above 10 ${\mu}g/mL$ concentration. These results indicate that RD would be used the functional food material.

Melittia inouei (Yuri Nabang) larvae are used as a crude drug in East Asia for treating stomach cancer and inflammation, and currently reared as a pharmaceutical insect in Jejudo, Korea. This study evaluated the immuno-modulating activity of these extracts, by determining the level of, cytokine production from mouse splenocytes stimulated with the extracts. The Melittia inouei larvae extracts did not induce the splenocyte proliferation. On the other hand, they stimulated the splenocytes to produce cytokines such as $TNF-{\alpha}$, whereas they did not stimulate IL10, IL12 or $IFN-{\gamma}$. The aqueous portion of its plant (Tri-chosanthis kirilowii) extract (sap) was found to be a potent inducer of NO production from the CPAE cells. However, it showed weak inhibitory effects on vascular endothelial growth factor (VEGF) production from splenocytes. These data suggests that a Melittia inouei larvae extract immune modulatory activity in cytokine prodcutions such as $TNF-{\alpha}$ and VEGF which might be related its anticancer effect.

Cisplatin(cis-diamminedichloroplatium) is one of the most effective anti-cancer drugs being clinically used in the treatment of solid tumors. Despite its therapeutic benefits, its use in clinical practice is often limited because of dose related toxicity. It is known that yeast cell wall beta-glucans possess immuno-modulating properties, which allows for their application in antitumor therapy. IS2 is a kind of beta-glucan derived from the cell wall of mutated Saccharomyces cerevisiae, which exhibits anti-cancer activity in vitro and in vivo. The present study explored the possibility of combination therapy of IS2 with cisplatin. In experimental metastasis of colon26-M3.1 cells, prophylactic intravenous administration of IS-2 in combination with cisplatin effectively inhibited tumor metastasis compared with cisplatin alone or IS-2 treatment in vivo. IS-2 effectively enhanced Th1 type cytokines including IFN-$\gamma$, IL-2, IL-12 and GM-CSF. Simultaneously, this combined treatment inhibited production of Th2 type cytokines compared with control. These results suggested that IS-2 can be applied in combination therapy with anti-cancer drugs to minimize their side effects.

The mycelial dispersed growth of Cordyceps sinensis was optimized in submerged batch culture at initial pH of 5.0, 150 rpm, and $25^{\circ}C$. The morphological data showed much more dispersed growth of C. sinenesis at initial pH of 5.0. Also, projected area, main hyphal length and number of tips for the mycelial growth of initial pH 5.0 were higher than those of other initial pHs. The industrial medium for mycelial production of C. sinensis was determined to be molasses of 100 g and crushed brewery yeast of 10 g per liter as carbon and nitrogen sources, respectively. With these culture conditions, the maximum production of mycelia was approximately 30.0 g per liter by batch culture in 5-liter jar fermenter with no controlled pH. This result suggests that large-scale mycelia production of C. sinensis may be possible in submerged batch culture. The hot water extract of mycelia from C. sinensis was mainly composed of 83.0% carbohydrate, 11.8% protein, 1.9% lipid, and 2.4% ash and there were present glucose, mannose, galactose, and arabinose as molar ratio of 8.79 : 2.59 : 1.34 : 1.0 in the carbohydrate, respectively. In the experiment using spleen cell and macrophage, the extract showed potent mitogenic and immuno-stimulating activities and among various components, an important factor that contribute to the immunological activities was turned out to be carbohydrate moiety.

Objectives: The purpose of this study was to investigate the effects of Gardeniae Fructus Water Extract (GF) on the production of inflammatory mediators in RAW 264.7 cell treated with lipopolysaccharide (LPS). Methods: Gradeniae Fructus was extracted with distilled water (2,000 ml) for 2 hours. In order to evaluate cytotoxicity of GF, 3 - (4,5-dimethylthiazol-2-yl) - 2,5 - diphenyltetrazolium bromide (MTT) assay was performed. To investigate antiinflammatory effects, the concentration of nitric oxide (NO) was measured with No assay, calcium (Ca) was measured with Fluo-4 Ca assay, and cytokine was measured by Bio-Plex cytokine assay in RAW 264.7 cell. And when p-value is below 0.05, it is judged to have the significant difference statistically. Results: 1. GF did not show any cytotoxicity. 2. GF suppressed the production of NO and Ca at the concentration of 25, 50, 100 and $200{\mu}g/ml$. 3. GF suppressed the production of interleukin (IL)-$1{\beta}$, IL-10, IL-12p40, macrophage-colony stimulating factor (M-CSF), macrophage inflammatory protein (MIP)-$1{\beta}$ and keratinocyte chemoattractant(KC) at the concentration of 25, 50, 100 and $200{\mu}g/ml$. 4. GF suppressed the production of vascular endothelial growth factor (VEGF), granulocyte-colony stimulating factor (G-CSF) and monocyte cheomattractant protein (MCP)-1 at the concentration of 25, 50 and $100{\mu}g/ml$. 5. GF suppressed the production of granulocyte macrophage-colony stimulating factor (GM-CSF) and regulated on activation, normal T cell expressed and secreted (RANTES) at the concentration of 25 and $50{\mu}g/ml$. 6. GF suppressed the production of MIP-2 at the concentration of 50 and $100{\mu}g/ml$, and tumor necrosis factor (TNF)-${\alpha}$ at the concentration of 50 and $200{\mu}g/ml$. Conclusions: These results suggest that GF has anti-inflammatory effect and immuno-modulating activity.

UV-protection skin whitening and immune activities several parts of Acer mono and Acer okamotoanum were investigated. The bark of both Acer mono and Acer okamotoanum had higher yields than other parts as 2.67% and 2.45%. The cytotoxicity of the extracts were lower than 21.64% against human skin cell(CCD-986sk) line in adding 1.0 mg/mL of the highest concentration. The bark extracts of Acer mono greatly reduced the expression of MMP-1 on UV-irradiated CCD-986sk cells down to as 30%. At 1.0 mg/mL of bark extration of Acer mono, $PGE_2$ expression was also significantly decreased. Generally, the bark extracts of Acer mono and Acer okamotoanum had higher activity than other parts, but, interestingly, wood extract of Acer okamotoanum showed strong inhibition effect on melanin production by Clone-M3 cells as 79.25%. From these results, we could conclude that the bark extract from Acer mono and Acer okamotoanum had skin-whitening activity as well immune enhancement activity.
