Objectives: This study was designed to investigate intestinal immune system activation and antimetastatic effect of Ojeok-san on cancer cells by oral administration. Methods: Cell viability of Ojeok-san was tested with colon 26-M3.1 carcinoma cells and Peyer's patch cells in vitro. Antimetastatic experiments were conducted in vivo mouse model by using colon 26-M3.1 carcinoma cell. To observe immunomodulating effects of Ojeok-san on Peyer's patch cells, we measured interleukin (IL)-4, GM-CSF. In addition to observing effects of Ojeok-san on hematopoiesis, we measured proliferation of bone marrow cells mediated by Peyer's patch cells in vitro. IgA induction activated in serum and intestinal content was measured to observe the effect of orally administered Ojeok-san on mucosal immune system. After administering Ovalbumin (OVA) with Ojeok-san, Proliferation of Peyer's patch cell was measured to investigate gut immunostimulatory effect. Results: in vitro cytotoxicity analysis, the inhibitory concentration $(IC)_{50}$ of the colon 26-M3.1 carcinoma cell was $890{\mu}g/ml$. $IC_{50}$ of the Peyer's patch cells with LPS was $990{\mu}g/ml$. We found that orally administered Ojeok-san significantly inhibited tumor metastasis in vivo. In addition, the amounts of IL-4 and GM-CSF in the culture supernatant of Peyer's patch cells were significantly increased compared to the control group. The proliferation of bone marrow cell was significantly up-regulated with Ojeok-san. These results indicate that oral administration of Ojeok-san enhances the secretion of hematopoietic growth factors such as GM-CSF and IL-4 from Peyer's patch cells, and these cytokines also act on modulator of bone marrow cell proliferation. After orally administering Ovalbumin (OVA) with Ojeok-san, IgA induction and Proliferation of peyer's patch cell was up-regulated with Ojeok-san. These results means orally administered Ojeok-san activates intestinal immune system and has an inhibitory effect on tumor metastasis. Conclusions: Orally administered Ojeok-san appears to have considerable activity on the anti-metastasis by activation of immune system.

Objectives : We investigated the effect of Dohongsamul-tang (DHSMT) on the production of various cytokines in lipopolysaccaride (LPS) stimulated peripheral mononuclear cells (PBMCs) from CI patients. Methods: Cell viability was determined using MTT assay. ELISA was carried out for investigating $TNF-{\alpha}$, $IL-1{\beta}$, IL-6, IL-8, IL-4, and $TGF-{\beta}$ 1 Results : The amount of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$, IL-6, IL-8, IL-4, and transforming growth factor(TGF)-${\beta}$ 1 in PBMC culture supernatant significantly increased in the LPS treated cells compared to unstimulated cells. We show that DHSMT inhibited the production of TNF-${\alpha}$, IL-1${\beta}$, IL-6, IL-8, and IL-4 induced by LPS in a dose dependent manner. The maximal inhibition rate of the TNF-${\alpha}$, IL-1${\beta}$, IL-6, IL-8, and IL-4 production by pretreatment of DHSMT (1.0mg/ml) was 38.52 ${\pm}$ 2.5% (P < 0.01), 44.02 ${\pm}$ 3.5% (P < 0.05), 45.32 ${\pm}$ 2.3% (P < 0.01), 42.30 ${\pm}$ 3.1% (P < 0.05), and 49.70　${\pm}$　3.1%(P ＆lt; 0.05), respectively. On the other hand, DMSMT significantly increased the LPS-induced TGF-${\beta}$ 1 production(P<0.05). Conclusions : Taken together. these results suggest that DHSMT might have regulatory effects on cytokine production, which might explain its beneficial effect in the treatment of CI.

Bangpungtongseong-san(BPTSS, Fangfengtongsheng-san in Chineses) is a traditional herbal formula comprising 18 medicinal herbs. In the present study, we performed the simultaneous analysis for four compounds of BPTSS and examined anti-allergic effects in human keratinocytes and mouse splenocytes. The column for separation of four compounds was used Luna C18 column and maintained at 40℃. The mobile phase for gradient elution consisted of two solvent systems. The analysis was carried out at a flow rate of 1.0 mL/min with PDA detection at 254 and 280 nm. To evaluate production and expression of Th2 chemokines, ELISA and RT-PCR were conducted in tumor necrosis factor (TNF)-α and interferon (IFN)-γ-stimulated HaCaT cells with or without BPTSS or silymarin, a positive control for skin inflammation. To measure Th2 cytokines, primary mouse splenocytes were treated with BPTSS and performed ELISA for interleukin (IL)-4, 5, 13. Calibration curves were acquired with r2>0.9999. The contents of geniposide, liquiritin, baicalin, and glycyrrhizin in BPTSS were 5.06 ㎎/g, 7.33 ㎎/g, 27.56 ㎎/g, and 7.81 ㎎/g, respectively. BPTSS reduced TARC and RANTES production and mRNA expression in TNF-α and IFN-γ-treated HaCaT cells. BPTSS inhibited IL-4, 5, and 13 production in mouse splenocytes. Our data will be a helpful information to upgrade quality control and anti-allergic effects of BPTSS.

This study was performed to determine the effect of dietary supplementation of procyanidin on growth performance, blood characteristics, and immune function in growing pigs. In experiment 1 (Exp. 1), thirty-two crossbred pigs with an initial BW of $19.2{\pm}0.3$ kg were allocated into 4 treatments for an 8-wk experiment: i) CON (basal diet), ii) MOS 0.1 (basal diet+0.1% mannanoligosaccharide), iii) Pro-1 (basal diet+0.01% procyanidin), and iv) Pro-2 (basal diet+0.02% procyanidin). Pigs fed Pro-1 and Pro-2 diets had greater (p<0.05) gain:feed ratio compared with those fed CON or MOS 0.1 diets. Serum creatinine concentration was less (p<0.05) in Pro-2 treatment than those in CON, MOS 0.1 and Pro-1 treatments. In Exp. 2, twelve pigs (BW $13.4{\pm}1.3$ kg) received basal diet with i) 0 (CON), ii) 0.02% (Pro-0.02%), and iii) 0.04% procyanidin (Pro-0.04%) for 4 wk. Concentration of platelets was lower (p<0.05) in the Pro-0.04% group compared to CON at 24 h after lipopolysaccharide (LPS) challenge. In addition, secretion of cytokines from cultured peripheral blood mononuclear cells (PBMC) in the presence or absence of procyanidin was examined. The levels of interleukin (IL)-$1{\beta}$, IL-6 and tumor necrosis factor (TNF)-${\alpha}$ were lower (p<0.05) in Pro (LPS-stimulated PBMCs+procyanidin) than those in CON (LPS-stimulated PBMCs+PBS) at 4 h after LPS challenge. These data suggest that dietary addition of procyanidin improves feed efficiency and anti-inflammatory cytokines of pigs.

Macrophages generated in vitro using macrophage-colony stimulating factor (M-CSF) and interleukin (IL)-6 from bone marrow cells (BM-Mp) are defective in antigen presenting cell (APC) function as shown by their ability to induce the proliferation of anti-CD3 mAb-primed syngeneic T cells. However, they do express major histocompatibility (MHC) class I and II molecules. accessory molecules and intracellular adhesion molecules. Here we demonstrate that the defective APC function of macrophages is mainly due to production of $TGF-{\beta}1$ by BM-Mp. Methods: Microarray analysis showed that $TGF-{\beta}1$ was highly expressed in BM-Mp, compared to a macrophage cell line, B6D. which exerted efficient APC function. Production of $TGF-{\beta}1$ by BM-Mp was confirmed by neutralization experiments of $TGF-{\beta}1$ as well as by real time-polymerase chain reaction (PCR). Results: Addition of $anti-TGF-{\beta}1$ monoclonal antibody to cultures of BM-Mp and anti-CD3 mAb-primed syngeneic T cells efficiently induced the proliferation of syngeneic T cells. Conversely, the APC function of B6D cells was almost completely suppressed by addition of $TGF-{\beta}1$. Quantitative real time-PCR analysis also confirmed the enhanced expression of $TGF-{\beta}1$ in BM-Mp. Conclusion: The defective APC function of macrophages generated in vitro with M-CSF and IL-6 was mainly due to the production of $TGF-{\beta}1$ by macrophages.

We investigated the association between dietary habits/food group consumption patterns and early risk of metabolic syndrome (MetS), a main cause for metabolic disease. Study participants were recruited from the health promotion center in Dong-A University Hospital and public advertisement. Study subjects (n = 243, 21-80 years) were categorized into three groups: Super-healthy (MetS risk factor [MetS RF] = 0, n = 111), MetS-risk carriers (MetS RF = 1-2, n = 96), and MetS (MetS $RF{\geq}3$, n = 27). Higher regularity in dietary habits (breakfast-everyday, regular eating time, non-frequent overeating, and non-frequent eating-out) was observed in the Super-healthy group than in the MetS-risk carriers, and particularly in the MetS subjects. The relationship between food group consumption patterns and MetS-risk related parameters were investigated with adjustment for confounding factors. Fruit consumption was positively associated with HDL-cholesterol, and tended to be negatively associated with waist circumference, triglyceride, LDL-cholesterol, and insulin resistance (IR). The consumption of low-fat meats and fish, and vegetables was negatively associated with hs-CRP. Specifically, the consumption of seafoods belonging to the low-fat fish was negatively associated with fasting glucose, hs-CRP, and interleukin (IL)-6. Anchovy/dried white baits consumption was negatively associated with fasting insulin and IR. Green-yellow vegetables consumption was negatively associated with fasting insulin, IR, and hs-CRP. On the other hand, sugars and fast-foods were positively associated with LDL-cholesterol. Additionally, fast-foods consumption was positively associated with hs-CRP and IL-6 levels. In conclusion, dietary habits/food group consumption patterns are closely associated with MetS-risk related parameters in Koreans. It may suggest useful information to educate people to properly select healthy foods for early prevention of MetS.

Background: Although neuropathic pain is a severe and common pain, its pathophysiology has not been elucidated yet. Studies in recent years have focused on the immune system's role in the pathogenesis of neuropathic pain. The aim of this study was to investigate the role of immunological mechanisms in neuropathic pain and the effect of pregabalin by measuring immunological marker levels in peripheral blood before and after pregabalin treatment in postherpetic neuralgia (PHN) patients with neuropathic pain. Methods: Forty patients diagnosed with PHN were included in the study. CD4, T follicular cells (Tfh: CD4⁺CXCR5⁺PD1⁺), Th17 (CD4⁺CCR6⁺ and CD4⁺IL17A⁺), regulatory T cells (Treg: CD4⁺ CD25⁺foxp3⁺), Th1 (CD4⁺ CXCR3⁺ and CD4⁺ IFN-γ⁺) and Th2 (CD4⁺ IL-4⁺) cell ratios were measured in peripheral blood samples before treatment and after 3 months of treatment. Results: When immunological marker and inflammation parameter levels were compared before and after treatment, the helper T cell ratio (CD3⁺, CD4⁺) was 30.28 ± 12.27% before treatment and 34.93 ± 11.70% after treatment, so there was a statistically significant increase (P = 0.028). Th17 was 4.75 ± 5.02% before treatment and 5.80 ± 3.13% after treatment, and there was a statistically significant increase (P = 0.036). Conclusions: Immunological mechanisms play an essential role in the pathogenesis of neuropathic pain, immunologically based treatment approach will be the critical point of treatment.

The Lauraceae family has commercial uses, such as in the food, pharmaceutical, and perfume industries. This study was conducted to investigate anti-asthmatic activity of essential oils from the seven species in the Lauraceae family. The essential oils were extracted from the leaves of seven species, and the chemical composition was investigated by gas chromatography-mass spectrometry. The major constituents of essential oils differed depending on the species, even if they belonged to the same family. The main constituents were camphor (89.09%) in Cinnamomum camphora, linalool (26.91%) in Cinnamomum cassia, 1,8-cineole (23.90%) in Cinnamomum japonicum, d-limonene (10.27%) and β-eudesmol (10.03%) in Lindera obtusiloba, δ-cadinene (13.85%) and α-phellandrene (11.57%) in Machilus japonica, cis-,trans-β-ocimene (13.80% and 12.06%) and elemol (11.46%) in Neolitsea aciculata, and cis-β-ocimene (37.94%) and sabinene (24.91%) in Neolitsea sericea. The anti-asthmatic activity of essential oils was investigated using the lipopolysaccharide-induced NCI-H292 cells. The relative expression levels of the pro-inflammatory cytokines [interleukin (IL)-1β and IL-6] and mucus gene (MUC5AC and MUC5B) were significantly reduced by essential oils from seven species in the Lauraceae family. Among the seven essential oils, the essential oil from L. obtusiloba had the most superior anti-asthmatic activity. These results suggest that the essential oil of L. obtusiloba leaves could be used as an agent to suppress mucus hypersecretion.

Objectives : This study was performed to compare the effect of two Cudrania tricuspidata cultivars; Sancheong native (CT) and varieties in china(SCT) on immediate hypersensitivity of the anaphylactic type and Ova-induced allergic asthma mouse model by calculating serum cytokines and IgE. Methods : We investigated the free radical scavanging effect and quantify total phenol contents and total flavonoids of two Cudrania tricuspidata cultivars; Sancheong native(CT) and varieties in china(SCT). The sample was extracted by 80% EtOH. To induce the allergic asthma, in the control group and the CT group, mice of each group were sensitized intraperitoneally with ovalbumin (OVA) solution at the 1st, the 7th and the 14th day. After then, sensitization was performed by aerosol allergen challenges with 1% OVA solution intratracheally at the 21th, the 23th, 25th and the 27th day. At the 29th day, the mice were killed and the changes of interferon-${\gamma}$, interleukin-4, 5 and 10, total IgE and OVA-specific IgE in serum were checked. Results : CT inhibited compound 48/80-induced systemic anaphylaxis 90% with a dose of 100 mg/kg body weight at 1 hr before injection of compound 48/80. In the allergic asthma mouse model, IFN-${\gamma}$ was did not increased in the CT and SCT group than that in the control group. IL-4, IL-5, the total IgE and OVA-specific IgE were decreased in the CT group as compared with the control group and these results were statistically significant. Conclusions : Considering the above experimental results, this study showed that Sancheong native cultivar could reduce the allergic reaction.
