Inonotus obliquus is one of the immune-regulatory substances and is recognized to play the role in the metabolic process of inflammation, allergy and immuntiy. The purpose of this study was to evaluate the effects of water extracts of Inonotus obliquus (IOW) on the liver lymphocyte immune function in the Sprague-Dawley male rats treated with carbon tetrachloride ($CCl_4$) to induce liver damage. Rats were fed with each experimental diet and water for 4 weeks. We found that effects of IOW on interferon-gamma (IFN-$\gamma$), signal transducer and activator of transcription 1 (STAT1), phospho-signal transducer and activator of transcription 1 (pSTAT1) and GATA-binding protein 3 (GATA-3) were decrease in vivo. Interleukin-4 (IL-4), STAT6, pSTAT6 and T-box expressed in T-cells (T-bet) decreased significantly lower in $CCl_4$+IOW group than the $CCl_4$ group. Our data indicated that cytokine protein production were increased in $CCl_4$ group and $CCl_4$+IOW group. As a result of this study, we assume that IOW fed could regulate the immuno-modulating functions through regulate the cytokine production capacity activated by liver damage.

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.

Objectives: This study was designed to examine immuno-modulatory effects of Evodia Rutaecarpine by activating innate immune system and inhibiting inflammation. Methods: First, Cell cytotoxicity was examined with 4T1 breast carcinoma and TG-induced macrophage. To investigate activating innate immune system of Evodiamine Rutacarpine Extract (ERE) on macrophage, we tested tumor necrosis factor-alpha (TNF-α), interleukin-12 (IL-12), and interleukin-6 (IL-6). In addition, TNF-α and nitric oxide (NO) induced by lipopolysaccharide (LPS) were measured after treating with ERE to observe innate immune modulating effect of ERE on RAW 264.7 cell. Also, mitogen-activated protein kinase (MAPK) and nuclear factor κB (NF-κB) were examined by western blot analysis. Results: In cytotoxicity analysis, ERE significantly affected tumor cell growth above specific concentration. Also, ERE significantly affected macrophage growth above specific concetration. As compared with the control group, the production of TNF-α, IL-12 and IL-6 were increased in TG-induced macrophage. As compared with the control group, TNF-α and IL-6 were significantly up-regulated in RAW 264.7 cell. The expression of TNF-α and NO induced by LPS after treating ERE was significantly decreased compared with control group. In addition, We observed ERE inhibited the phosphorylation levels of p-extracellular signal-regulated kinase (p-ERK), p-Jun N-terminal kinase (p-JNK), and p-p38 in western blotting by treating ERE on RAW 264.7 cell. Conclusions: ERE seems to have considerable impact on the anti-cancer effect by activation of innate immune system and inflammation control.

Objectives : To clarify the possible effect of JS (Juglans sinensis), PCF (Psoralea corylifolia L.), and J+P(JS+PCF), we examined their influence on the development of pulmonary eosinophilic inflammation in the asthmatic murine model. Methods : All mice were immunized on two different days (21 days and 7 days before inhalational exposure) by intraperitonial injections of 0.2 ml alum-precipitated Ag containing 100 ${\mu}$g of OVA bound to 4 mg of aluminum hydroxide in PBS. Seven days after the second sensitization, mice were exposed to aerosolized ovalbumin for 30 minutes/day on 3 days/week for 8 weeks (at a flow rate of 250 L/min, 2.5% ovalbumin in normal saline) and, JS, PCF and J+P (200 mg/kg, 400 mg/kg) were orally administered 3 times per week for 8 weeks. Results : The suppressive effects of JS, PCF, and J+P were demonstrated by the accumulation of eosinophils into airways, with the reduction of eosinophils and lung leukocytes. These were correlated with the marked reduction of IL-4, IL-5, IL-13 levels in the BALF and serum. OVA-specific IgE levels were also decreased in serum and BAL from these mice. And also JS, PCF, and J+P decreased eosinophilic CCR3 and CD11b expression in lung tissue. Conclusions : These results indicate that JS, PCF, and J+P have deep inhibitory effects on airway inflammation and hyper-responsiveness in the asthmatic murine model. The suppression of IL-5, IgE, and eosinophilils and the increase of IFN-${\gamma}$ production in BALF seem to contribute to these effects. Specially, esosinophils and TNF-a in J+P combination group were significantly reduced in BALF and lung tissue. Hence, the results indicated that JS, PCF, and J+P could act as an immuno-modulator which possesses anti-inflammatory and anti-asthmatic property by modulating the imbalance between Th1 and Th2 cytokines.

Oudemansiella radicata, edible and medicinal mushroom belonging to Agaricales of Basidiomycota, has been known to exhibit outstanding curative effects on the fungal infection and hypertension caused by high blood pressure. Neutral saline soluble (0.9% NaCl), hot water soluble and methanol soluble substances (hereinafter referred to Fr, NaCl, Fr. HW and Fr. MeOH, respectively) were extracted from fruiting body of the mushroom. In vitro cytotoxicity test showed that Fr. NaCl was not cytotoxic against NIH3T3 and Sarcoma 180 at the concentration of $10{\sim}1,000\;{\mu}g/ml$. Intraperitoneal injection with Fr. NaCl exhibited antitumor activity with life prolongation effect of $42.9{\sim}66.7%$ in mice inoculated with Sarcoma 180. Fr. NaCl improved the immunopotentiating activity of B lymphocyte by increasing the alkaline phosphatase activity by $1.4{\sim}3$ folds compared with controlled and LPS groups, respectively. Intraperitoneal injection with Fr. MeOH increased the numbers of peritoneal exudate cells and circulating leukocytes by 3.5 and 2.5 folds, respectively. Therefore, the antitumor effect exhibited on mouse Sarcoma 180 cells was likely due to immune-modulating activity of crude polysaccharides extracted from fruiting body of O. radicata.

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.

The purpose of this study was to investigate the immunomodulatory effect of Ulva pertusa kjellman extract after undergoing a low temperature and high-pressure extraction process. First, the extracts obtained under the extraction conditions of 150 MPa and $80^{\circ}C$showed a relatively high antioxidant activity, with 90% super oxide radical activity compared to the extracts from conventional extraction process with water at $100^{\circ}C$. This extract also improved the growth of both human immune B and T cells up to $14.5{\times}10^4$ cells/mL and $14.2{\times}10^4$ cells/mL compared to $9.1{\times}10^4$ cells/mL in adding the extracts from conventional processes. It was found that the extracts obtained at 100 MPa and $60^{\circ}C$ showed better activities in NK cell growth and NO production from macrophage as $11.8{\times}10^2$ cells/mL and 30.0 ${\mu}M$. Overall, the extracts from high pressure and low temperature extraction process had relatively higher immune activation activity, possibly because the low temperature and high pressure extraction process may have higher yields of active compounds and have less damage to useful ingredients from relatively weak marine natural resources, such as Ulva pertusa kjellmann than that from the conventional extraction system.

This study was performed to compare the effects of immuno-modulating activities of Rhodiola sachalinensis A. Bor. fractionized by consecutive solvent separation. The Cytotoxicity of all fractionized extracts on human kidney cell (HEK293) was lower than crude extracts. Generally, the butanol and chloroform extracts showed less cytotoxicity on about 10.07% and 9.67% than the crude extracts. For human immune B and T cell growth, chloroform fraction showed the highest cell growth compared to the control. The secretion of cytokines (IL-6, $TNF-\alpha$) on human B and T cells were increased by adding chloroform extracts. Also, NK cell growth was significantly improved up to nearly 30% by adding the supernatant of B cell medium grown with the chloroform fraction. It was also found that chloroform fraction could yield higher nitric oxide production from macrophage than untreated control cells. Differentiation of HL-60 cells was increased up to 131.9% after treatment with chloroform fraction extracts, compared to the control. These results indicate that the chloroform fraction of R. sachalinensis have high immune activation activity than others fractions and the crude extracts, implying that this chloroform fractions could be used a new functional material.

Objective: We previously described that Diva is highly expressed in matured metaphase II (MII) oocytes compared to immature germinal vesicle (GV) oocytes in mouse. We report here that the expression of Diva transcript as well as protein is oocyte-specific. To elucidate its physiological role in oocyte, the binding partner(s) of Diva has been identified by using immunoprecipitation (IP) followed by Mass Spectrometry. Methods: NIH/3T3 cells were transiently transfected for 24 h with either empty vector for control or FLAG-tagged mouse Diva construct, and IP was performed with anti-FLAG antibody. The immuno-isolated complexes were resolved by SDS-PAGE on a 12% gel followed by Coomassie Blue staining. For in-gel digestion, 15 bands of interest were excised manually and digested with trypsin. All mass spectra were acquired at a positive reflector mode by a 4700 Proteomics Analyzer (Applied Biosystems, Framingham, MA). Proteins were identified by searching the NCBI nonredundant database using MASCOT Peptide Mass Fingerprint software (Matrixscience, London). Results: Diva-associated complexes were formed in FLAG-tagged mouse Diva-overexpressed NIH/3T3 cells via IP using anti-FLAG-conjugated beads. Among the excised 15 bands, actin and actin-binding proteins such as tropomyosin, tropomodulin 3, and ${\alpha}$-actinin were identified. Binding between Diva and actin or tropomyosin was confirmed by IP followed by Western blot analysis. Both bindings were also detected endogenously in mouse ovaries, indicating that Diva works with actin and tropomyosin. Conclusions: This is the first report that immuno-isolated Diva-associated complexes are related to actin filament of the cytoskeletal system. When we consider the association of Diva with actin and tropomyosin, oocyte-specific Diva may play a role in modulating the cytoskeletal system during oocyte maturation.
