A Effect on physiological metabolism of microorganism which irradiated by visible light of non-ionization radiation(12,000 Lux) was investigated. The microorganism used in this experiment was a Rhodospirillum rubrum KS-301 of chemosynthetic microorganism. Batch fermentation of glucose were implement, and based on the data resulted from the fermentation. First, physiological characteristic of microorganism which was not irradiated was investigated. As a result, the decrease of the residual quantity of the substance(5.03 g/L - 2.17 g/L) was increased with the quantity of the bacteria(1.08 g/L - 3.14 g/L)and the quantity of the hydrogenous production(0.186 g - 0.3 g) respectively. Second, physiological characteristic of microorganism which was irradiated was investigated. As a result, the decrease of the residual quantity of the substance(13.17 g/L - 5.2 g/L) was increased with the quantity of the bacteria(4.7 g/L - 10.57 g/L)and the quantity of the hydrogenous production(0.186 g - 0.3 g) respectively. As the physiological characteristic of microorganism which was irradiated by visible light of non-ionization radiation(12,000 Lux) was active with its life, but the cell damages irradiated by with gamma-ray, X-ray, electron-ray in ionization radiation were appeared at cell.

Adipose tissue deposited within muscle fibers, known as intramuscular fat (IMF or marbling), is a major determinant of meat quality and thereby affects its economic value. The biological mechanisms that determine IMF content are therefore of interest. In this study, 48 genes involved in the bovine peroxisome proliferator-activated receptor signaling pathway, which is involved in lipid metabolism, were investigated to identify candidate genes associated with IMF in the longissimus dorsi of Hanwoo (Korean cattle). Ten genes, retinoid X receptor alpha, peroxisome proliferator-activated receptor gamma (PPARG), phospholipid transfer protein, stearoyl-CoA desaturase, nuclear receptor subfamily 1 group H member 3, fatty acid binding protein 3 (FABP3), carnitine palmitoyltransferase II, acyl-Coenzyme A dehydrogenase long chain (ACADL), acyl-Coenzyme A oxidase 2 branched chain, and fatty acid binding protein 4, showed significant effects with regard to IMF and were differentially expressed between the low- and high-marbled groups (p<0.05). Analysis of the gene co-expression network based on Pearson's correlation coefficients identified 10 up-regulated genes in the high-marbled group that formed a major cluster. Among these genes, the PPARG-FABP4 gene pair exhibited the strongest correlation in the network. Glycerol kinase was found to play a role in mediating activation of the differentially expressed genes. We categorized the 10 significantly differentially expressed genes into the corresponding downstream pathways and investigated the direct interactive relationships among these genes. We suggest that fatty acid oxidation is the major downstream pathway affecting IMF content. The PPARG/RXRA complex triggers activation of target genes involved in fatty acid oxidation resulting in increased triglyceride formation by ATP production. Our findings highlight candidate genes associated with the IMF content of the loin muscle of Korean cattle and provide insight into the biological mechanisms that determine adipose deposition within muscle.

Inflammation is a protective response to infection or injury. However, prolonged inflammation can contribute to the pathogenesis of many diseases, such as cancer, diabetes, arthritis, atherosclerosis, and Alzheimer's disease. Recent studies have shown that activated macrophages, inflammatory effector cells, can react to tissue insults in a polarized manner, in which their phenotypes are polarized into two major subtypes, categorized as M1 or M2. Classical M1 activation involves the production of pro-inflammatory cytokines, such as interleukin (IL)-6 and tumor necrosis factor (TNF)-${\alpha}$, and free radicals, while M2 or alternative activation is an anti-inflammatory phenotype involved in homeostatic processes, such as wound healing, debris scavenging, and the dampening of inflammation via the production of very low levels of pro-inflammatory cytokines and high levels of anti-inflammatory mediators, including IL-10. As part of our ongoing effort to isolate anti-inflammatory compounds from seaweeds, we investigated the effects of phlorotannins isolated from the brown alga Ecklonia stolonifera on macrophage polarization. Mouse peritoneal macrophages were treated with various concentrations of the extracts, and real-time RT-PCR analyses were performed to examine the expression of polarization markers: IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ for M1 and arginase-1, peroxisome proliferator-activated receptor (PPAR)-${\gamma}$, found inflammatory zone-1 (Fizz-1), chitinase 3-like 3 (Ym1), and$Kr{\ddot{u}}ppel$-like factor 4 (Klf-4) for M2. The pretreatment of cells with eckol, dieckol, and phlorofucofuroeckol-A (PFF-A), isolated from the ethyl acetate fraction of E. stolonifera ethanolic extract, potentiated the anti-inflammatory M2 phenotype of the macrophages. These results indicate that phlorotannins derived from E. stolonifera can be used to enrich macrophages with markers of the M2 anti-inflammatory state.

Scutellariae Radix (Scu.), one of the immune-regulatory substances, is recognized to play the role in the metabolic process of inflammation, allergy and immunity. It has been traditionally used in the Oriental medicine to treat inflammatory bowel diseases (IBD). The purpose of this study was to evaluate the effects of water extracts of Scutellariae Radix on the spleen lymphocyte immune function in the Balb/c female mice treated with dextran sodium sulfate (DSS) to induce colitis. Water extract of Scutellariae Radix (100 mg/kg) and sulfasalazine (50 mg/kg) were administrated orally for 2 weeks of experimental period. Mice were divided into three experimental groups randomly: DSS group (5％ DSS was ad libitum for 5 days) as control group, DSS ＋ Scu. (water extracts of Scutellariae Radix for 2 weeks after 5％ DSS was ad libitum for 5 days) as experimental group, and DSS ＋ Sulfasalazine group (Sulfasalazine for 2 weeks after 5％ DSS was ad libitum for 5 days) as positive control group. Levels of Ig A, Ig E, CD4$^{＋}$, CD8$^{＋}$, TNF-$\alpha$ and other cytokines were measured. Treatment of DSS for 5 days induced bowel inflammation and the treatment with Scu. water exteract and sulfasalazine significantly recovered the damage. The length of intestine of DSS group was significantly shorter than that of other groups. The serum and fecal concentration of Ig A of SS ＋ Scu group was higher than those of DSS group. The contents of CD4$^{＋}$ T cells was higher in the DSS ＋ Scu. group than the other groups and CD8$^{＋}$ T cells was the lowest in DSS ＋ Sulfasalazine group. The Ig A level of cultured supernatant of spleen lymphocyte was the highest, while the Ig E level was the lowest in SS ＋ Scu group. The concentration of TNF-$\alpha$, cytokine secreted from the Th1 cell in the supernatant spleen lymphocyte, was the highest in the DSS group and the lowest in the DSS ＋ Scu. group. The concentration of IFN-${\gamma}$ and ll...-12 was lower in the DSS ＋ Scu. group than those of the other groups. The concentration of IL-4 in the supernatant of spleen lymphocyte was the lowest in the DSS ＋ Scu. group but IL-10 was not significantly different. Based on these findings, water extract of Scutellariae Radix exhibited the inhibitory effect via IL-4 production thereby inhibited the production of Ig E and strengthened immune system, and alleviated injury in DSS- induced colitis mice model.

Objectives Dictamni Radicis Cortex extracts (DRC) has been known to suppress allergic reaction, however the cellular target of DRC and its mode of action remain unclear. The purpose of this study is to investigate the effects of Dictamni Radicis Cortex extracts on DNCB induced atopic dermatitis-like skin lesions of NC/Nga mouse. Methods This study was designed to investigate the effects of DRC extract in the DNP-IgE-induced activation of MC/9 murine mast cell lines in vitro and in the DNCB-induced activation of NC/Nga mouse in vivo. For this investigation, We examined IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$ and GM-CSF mRNA expression by Real-time PCR, IL-13, MIP-$1{\alpha}$ production by ELISA analysis and manifestations of NFAT1, NFAT2, AP-1 and NF-${\kappa}B$ p65 transcription factors by western blotting in vitro. Then, we examined WBC, eosinophil and neutrophil in NC/Nga mouse, IL-5, IL-13 in serum, IFN-${\gamma}$, IL-4 in the spleenocyte culture supernatant, the absolute cell numbers of $CD4^+$, $CD8^+$, $^+Gr-1^+CD11b$, $B220^+CD23^+$ in the ALN, PBMCs and dorsal skin, IL-5, IL-13 in the dorsal skin by Real-time PCR and the distribution of mast cells by H&E and toluidine blue. Results In vitro the mRNA expression of IL-4, IL-5, IL-6, IL-13, TNF-${\alpha}$, GM-CSF and IL-13, MIP-$1{\alpha}$ production by ELISA analysis were completely abolished by DRC and the western blot analysis decreased the expression of mast cell-specific transcription factors including NFAT-1, NF-${\kappa}B$ p65. In vivo DRC oral adminstration also decreased the counts of WBC, eosinophils and inflammatory cytokines such as IL-13 and IgE in the serum. DRC oral adminstration elevated IL-4 level in the spleenocyte culture supernatant. DRC oral adminstration decreased total ALN cells, total skin cells, cell numbers of $CD4^+$, $B220^+CD23^+$ in the ALN, $^+Gr-1^+CD11b$ in the PBMCs and $CD4^+$, $CD8^+$ in the dorsal skin. The mRNA expression of IL-5, IL-13, thickness of epidermis, inflammation immune cells and mast cells were abolished by DRC in the dorsal skin. Conclusions Histological examination showed that infiltration levels of immune cells in the skin of AD-induced NC/Nga mouse were much improved by DRC oral adminstration. These results, therefore, suggest that DRC can regulate molecular mediators and immune cells that are functionally associated with atopic dermatitis induced in NC/Nga mouse, and may play an important role in recovering AD symptoms.

The aim of this study was 1) to confirm the practical efficiency of a routine milk P4 monitoring system for postpartum reproductive management of a dairy herd, and 2) to evaluate the relationship between the blood metabolic profiles, milk quality and body weight of individual cows in the farm records, which may reflect the postpartum nutritional condition, and the time of postpartum resumption of ovarian activity of dairy cows. A total of 116 Holstein cows was used in the present study. First, during the period of Experiment 1, postpartum reproductive management based on weekly measured milk P4 concentration from individual cows was conducted. Compared with the reproductive records of the past two years without P4 monitoring, although the day from calving to first AI did not change, both the number of AI until pregnant (with P4; 1.9 times vs. without P4; 2.9 times) and the days open (with P4; 95.1 days vs. without P4; 135.8 days and 133.8 days) were significantly decreased. In Experiment 2, the measurement of blood constituents such as albumin, blood urea nitrogen, packed cell volume, ammonia, glucose, total cholesterol, non-esterified, AST and $\gamma$-GTP was performed on the blood samples taken once approximately 14 days postpartum, to monitor both health and nutritional conditions. The milk constituent parameters, such as milk protein (MP), milk fat (MF), SNF and lactose, collected from the monthly progeny test of individual cows, were used to monitor the postpartum nutritional status. Furthermore, the data obtained from the routine measurements of body weight were used to calculate the rate of peripartum body weight loss. The resumption day of the postpartum estrous cycle was assumed from the milk P4 profiles of individual cows. There was no clear relationship between each parameter from blood examination and those from resumption time. However, the cows had low values of MP, and SNF, which significantly affected the resumption of the postpartum estrous cycle. Similarly, a higher rate of body weight loss indicated a significant delay (more than 1 month) in the resumption of the postpartum estrous cycle, compared with the groups that had a medium or lower rate of body weight loss. The results of the present study demonstrated that the implementation of routine milk P4 monitoring-based postpartum reproductive management, together with milk quality parameters and routine BW data available in field conditions may be utilized as a practical approach for increasing the postpartum reproductive efficiency of a high yielding dairy herd.

In order to improve efficacy of oriental medicines and to study the application of fermented oriental medicine in clinicals, the efficacy of CYT and CYTBH on atopic dermatitis were evaluated. The results and conclusions are as follows. CYT and CYTBH significantly improved the atopic dermatitis symptoms in NC/Nga mice by naked eye evaluation and significantly decreased clinical index in both groups. CYT and CYTBH both decreased the cell numbers of CD3+, CD11b+Gr-1+ cells in dorsal skin. Of the cells, CYT significantly decreased CD11b+Gr-1+ cells whereas CYTBH significantly decreased all immune cells. CYT and CYTBH both decreased the production rate of IL-4 and IFN-${\gamma}$ activated by CD3/CD28. In the case of CYTBH, significant decrease in all cases was observed. CYT and CYTBH decreased the production rate of IL-5, IL-13 and IL-17 in serum. Significant decrease of IL-5 in the case of CYT and IL-5 and IL-13 in the case of CYTBH were observed. CYT and CYTBH significantly decreased transcription of IL-5 mRNA and IL-13 mRNA in skin. Significant decrease in IgG1 and IgE immunoglobulins in serum were oberved in both groups. Significant decrease was only observed in the case of CYTBH. Both CYT and CYTBH significantly decreased the secretion of histamine. Both CYT and CYTBH suppressed erythema, hemorrhage, edema, excoriation, erosion of skin tissues of NC/Nga mice resulting in the decrease of thickness of epidermis. Significant decrease of infiltration of obese cells was also observed. The results above indicated that both CYT and CYTBH had significant efficacy in the treatment of atopic dermatitis through immune modulation. Animal studies showed that CYTBH had superior activity than that of CYT suggesting further and continuous studies on the changes in ingredients or absorption improvement by fermentation should follow.

This study was performed to establish an effective extraction method of pig placenta extract that could be used for a putative functional food supplement with immunomodulatory effects. In the present study, we used different temperatures (4, 37, 60, 80, and $100^{\circ}C$) and different solvents (chloroform, NaOH, and phosphate buffered saline [PBS]) to extract the pig placenta. Among the different placenta extracts yielded by the different extraction methods, placenta extract (PE) in PBS at $80^{\circ}C$ for 30 min (referred to as PE-PBS80) showed a significant increase of nitric oxide production of up to 22.97 ${\mu}M/10^5$ cells at a 1 mg/mL dose (p<0.05 ) in J774A.1 cells than other extracts and control tested. Using PE-PBS80, further animal challenges were performed to identify the immune-enhanced effects. As a result, orally administered PE-PBS80 showed a significant increase in blood T and B cell activities and immunoglobulin (IgG and IgM) production. IgG and IgM levels increased to 41.53 mg/mL at a 20 mg dose on day 7 and to 27.38 mg/mL at a 10 mg dose on day 14, respectively (p<0.05). Furthermore, PE-PBS80 was also able to significantly enhance the immune modulator cytokine levels (p<0.05) compared to the control and vehicle treatments. Among the evaluated cytokines, the tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) level increased to 28.89 pg/mL at extract doses of 20 and 50 mg, the interleukin-$1{\beta}$ (IL-$1{\beta}$) level increased to 21.52 pg/mL at extract doses of 10, 20, 50 and 75 mg and the interferon (IFN)-${\gamma}$ level increased to 18.24 pg/mL at extract doses of 10, 20, and 50 mg. Therefore, this study presents an effective method for extracting pig placenta extracts and also demonstrates that pig placenta extracts had significant immunomodulatory effects not only at the cellular level but also in a mouse model, suggesting that this material could be used as an excellent candidate functional food supplement.
