  • The glasswort is an edible halophyte demonstrating various physiological effects including anti-inflammatory activity. In the present study, the effects of glasswort extracts on inflammatory events and interactions of THP-1 monocytes with intestinal epithelial cells were investigated. Five solvent fractions, including the ethylether fraction (Fr.E), were prepared from a 70% methanol extract of glasswort. THP-1 monocytes underwent differentiation by phorbol 12-myristate 13-acetate treatment and were then activated by lipopolysaccharide (LPS), which induced cyclooxygenase (COX)-2 expression. None of the glasswort fractions tested alone induced COX-2 in differentiated THP-1 cells. Fr.E, however, enhanced LPS-induced COX-2 expression in differentiated THP-1 cells. Culture media of THP-1 cells treated with each fraction stimulated the growth of normal intestinal INT-407 cells more prominently than that of HT-29 colon cancer cells. COX-2 expression in HT-29 cells was inhibited when the cells were exposed to the THP-1 culture medium treated with Fr.E. Thus, glasswort could modulate the interaction between immune cells and intestinal cells.

  • This study was conducted to investigate effect of feeding fermented hulless barley (FHB) on growth performance and blood metabolites in growing pigs. Forty-five pigs (LYD; initial body weight, $30.33{\pm}0.05kg$) were randomly allotted into three dietary treatments that consisted of 0, 0.5 and 1.0% of the FHB in the basal diets. The pigs fed 0.5% FHB showed higher average daily gain than the 0 and 1% FHB treatments, although there was not significant among the treatments. Similarly, average daily feed intake and feed conversion ratio were not different among the treatments. Blood white blood cells, neutrophil, lymphocyte, monocyte, eosinophil and basophil were ranged to reference values, but not difference among the treatments. Serum glucose was increased in the control compared with 0.5 and 1.0% FHB. However, parameters related to protein, lipid and mineral also were not different among the treatments. These results indicate the FHB has no significant effect of growth performance and metabolizable responses in growing-finishing pigs.

  • Orientia tsutsugamushi, a gram-negative bacterium, causes severe acute febrile illness in humans. Despite this danger, the route of infection, infectivity, and protective mechanisms of the host's immune response to O. tsutsugamushi are unclear. Dendritic cells (DCs) are one of the most important cell types in bridging the innate and adaptive immune responses. In this study, we observed that O. tsutsugamushi infects and replicates in monocyte-derived DCs (MODCs). During infection and replication, the expressions of the cytokines IL-12 and TNF-${\alpha}$, as well as the co-stimulatory molecules CD80, CD83, CD86, and CD40, were increased in MODCs. When O. tsutsugamushi-treated MODCs were co-cultured with autologous $CD4^+$ T cells, they enhanced production of IFN-${\gamma}$, a major Th1 cytokine. Collectively, our results show that O. tsutsugamushi can replicate in MODCs and can simultaneously induce MODC maturation and increase proinflammatory cytokine levels in MODCs that subsequently activate $CD4^+$ T cells.

  • Due to the lowering of biological functions resulted from old age, the elderly is known to have many different clinical laboratory data compared with the young adults. But, in korea, such study is lacking. This research is to find the differences between the elderly and the young adults, and also to know the sexual differences, by comparing the outcomes of the clinical. laboratory data. Along with that, it is to help clinical usage of the data in the future. The age of the elderly was between 60 and 83(average age 63.8), and that of the young. controls was between 20 and 35. In both sexes, MCV, MCH, ESR, CRP, AST, ALT, ${\gamma}$GTP, ALP, BUN, total cholesterol were significantly higher in the elderly than in the controls. And lymphocyte count(%), total bilirubin, direct bilirubin, total protein, albumin, $T_3$ were significantly lower in the elderly than in the controls(P<0.05). Hemoglobin, Hct, platelet count, $T_4$ were significantly lower only in the male elderly, and eosinophil count(%), creatinine were significantly higher only in the female elderly(P<0.05). HDL cholesterol was significantly higher only in the male elderly(P<0.01). There were no significant difference between two groups regarding WBC count, segment neutrophil count(%), monocyte count(%), TSH. Many clinical laboratory data are different between the elderly and the young adults, and some clinical laboratory data also have sexual differences.

  • This study was conducted to determine the valid time for accurate detection of complete blood cell count (CBC) in pig blood using an automatic blood corpuscle analyzer (Hemavet 950FS). Blood samples were collected from 34 pigs (Duroc) with a 60 kg (${\pm}3.5$) body weight. Ten specimens with CBC parameters in normal range and with no hemolysis were selected among 34 samples and used in this study. Regarding leukocytes parameters, white blood cell (WBC), neutrophil (NE), and lymphocyte (LY) counts showed a low daily variation (coefficient of variation, CV), whereas monocyte (MO), eosinophil (EO), and basophil (BA) CVs were significantly high (19.7, 56.9, and 53.3%, respectively). On the other hand, all parameters of erythrocytes and thrombocytes showed stable daily variation. All parameters of leukocytes and thrombocytes were significantly reduced as storage time passed (P<0.01 or 0.001), except for lymphocytes (P=0.535). However, no significant differences were observed in parameters of erythrocytes from blood up to 120 hours. From above results, we assert that Hemavet 950FS is useful in analyzing CBC, except for MO, EO, and BA. For accurate detection of leukocyte and thrombocyte parameters, analysis should be performed within 4 hours after blood collection when using Hemavet 950FS. On the other hand, parameters of erythrocytes could be stably detected for at least 120 hours after blood collection.

  • Background: Beneficial effects of Korean Red Ginseng (KRG) on polycystic ovarian syndrome (PCOS) remains unclear. Methods: We examined whether pretreatment (daily from 2 hours before PCOS induction) with KRG extract in water (KRGE; 75 and 150 mg/kg/day, p.o.) could exert a favorable effect in a dehydroepian-drosterone (DHEA)-induced PCOS rat model. Results: Pretreatment with KRGE significantly inhibited the elevation of body and ovary weights, the increase in number and size of ovarian cysts, and the elevation of serum testosterone and estradiol levels induced by DHEA. Pretreatment with KRGE also inhibited macrophage infiltration and enhanced mRNA expression levels of chemokines [interleukin (IL)-8, monocyte chemoattractant protein-1), proinflammatory cytokines (IL-1β, IL-6), and inducible nitric oxide synthase in ovaries induced by DHEA. It also prevented the reduction in mRNA expression of growth factors (epidermal growth factor, transforming growth factor-beta (EGF, TGF-β)) related to inhibition of the nuclear factor kappa-light-chain-enhancer of activated B cell pathway and stimulation of the nuclear factor erythroid-derived 2-related factor 2 pathway. Interestingly, KRGE or representative ginsenosides (Rb1, Rg1, and Rg3(s)) inhibited the activity of inflammatory enzymes cyclooxygenase-2 and iNOS, cytosolic p-IκB, and nuclear p-nuclear factor kappa-light-chain-enhancer of activated B in lipopolysaccharide-induced RAW264.7 cells, whereas they increased nuclear factor erythroid-derived 2-related factor 2 nuclear translocation. Conclusion: These results provide that KRGE could prevent DHEA-induced PCOS via antiinflammatory and antioxidant activities. Thus, KRGE may be used in preventive and therapeutic strategies for PCOS-like symptoms.

  • Background: Little information is available on the identification and characterization of the upstream regulators of the signal transduction cascades for Mycobacterium tuberculosis (M. tbc)-induced ERK 1/2 activation and chemokine expression. We investigated the signaling mechanisms involved in expression of CCL3 /MIP-1 and CCL4/MIP-1 in human primary monocytes infected with M. tbc. Methods: MAP kinase phosphorylation was determined using western blot analysis with specific primary antibodies (ERK 1/2, and phospho-ERK1/2), and the upstream signaling pathways were further investigated using specific inhibitors. Results: An avirulent strain, M. tbc H37Ra, induced greater and more sustained ERK 1/2 phosphorylation, and higher CCL3 and CCL4 production, than did M. tbc H37Rv. Specific inhibitors for mitogen-activated protein kinase (MAPK) kinase (MEK; U0126 and PD98059) significantly inhibited the expression of CCL3 and CCL4 in human monocytes. Mycobactetia-mediated expression of CCL3 and CCL4 was not inhibited by the Ras inhibitor manumycin A or the Raf-1 inhibitor GW 5074. On the other hand, phospholipase C (PLC) inhibitor (U73122) and protein kinase C (PKC)specific inhibitors ($G\ddot{o}6976$ and Ro31-8220) significantly reduced M. tbc-induced activation of ERK 1/2 and chemokine synthesis. Conclusion: These results are the first to demonstrate that the PLC-PKC-MEK-ERK, not the Ras-Raf-MEK-ERK, pathway is the major signaling pathway inducing M. tbc-mediated CCL3 and CCL4 expression in human primary monocytes.

  • One aspect of undesirable outcomes in orthodontic treatment includes excessive resorption of dental roots with mechanotherapy. The aim of this study is to demonstrate whether diseases affecting the immune system adversely are prevalent in orthodontic patients who manifest excessive resorption of dental roots with orthodontic tooth movement. The records of 51 orthodontic patients (25 males and 26 females, $16.1{\pm}3.3$ yr old) and 51 pair-matched controls ($1.5.4{\pm}4.1$ yr old) were analyzed retrospectively. The pretreatment questionnaires and the treatment records disclosed that the incidence of asthma, allergy, and signs indicative of psychological stress, was significantly higher in the root resorption cohort. The immune system is either altered or adversely affected in all these conditions. Since the progenitors of osteoclasts and odontoclasts are derived from mononucleated cells of monocyte and macrophage lineage, which are prominent cellular members of the immune system, the study leaded to the conclusion that excessive root resorption may occur in orthodontic patients who are psychologically stressed, or who have asthma and allergy, or any other conditions that may adversely affect and modify the immune system, and a careful examination and interpretation of a patient's medical history may be beneficial to both patient and practioner.

  • This study was performed to define the cytotoxicity and the anti-inflammatory action of Pulsatilla koreana extracts. To analyze cytotoxic effects, gingival and periodontal ligament fibroblasts were used, and anti-inflammatory actions related to reduction of $IL-1{\beta}$ and $PGE_2$ production were performed in vitro, for the suggestion of efficacy and safety on periodontal therapeutic use of Pulsatilla koreana extracts. We extracted ethylacetate and butylalcohol from well-dried and ground Pulsatilla koreana throughout multiple processing, then used different concentration solution(0.1 %, 0.2 %, 0.4 %, 0.01 %, 0.02 %, 0.04 %, 1 %, 2 %) of ethylacetate and butylalcohol extracts to examine eytotoxic effects and anti-inflammatory actions Cytotoxic effects were examined by ELISA reader using MTT(Methyl Thiazol-2-YL-2, 5-diphenyl Tetrazolium bromide)solution following culture of human gingival and periodontal ligament fibroblasts. Synthesis of $IL-1{\beta}$was examined by $IL-1{\beta}$ enzyme-immunoassay(EIA)system after separation and culture of monocyte, and $PGE_2$ was examined by $PGE_2EIA$ system after culture of gingival fibroblasts. The results were as follows: 1. In the MTT test of gingival fibroblasts, the change of optical density was decreased significantly at 2 % of butylalcohol extracts and 0.04 %, 0.1 %, 0.2 %, 0.4 %, 1 %, 2 % of ethylacetate extracts.(p<0.05) 2. In the MTT test of periodontal ligament cells, the change of optical density were not differ significantly. but butylalcohol and ethylacetate extracts except from butylalcohol 0.01 % showed high cell cytotoxity. 3. Both ethylacetate and butylalcohol extracts from Pulsatilla koreana inhibited the synthesis of $IL-1{\beta}$and inhibition effect of ethylacetate extracts were higher than butylalcohol extracts. 4. Both ethylacetate and butylalcohol extracts from Pulsatilla koreana inhibited the synthesis of $PGE_2$, and ethylacetate extracts were higher than butylalcohol extracts. In conclusion, ethylacetate and butylalcohol extracts from Pulsatilla koreana showed little cell cytotoxity for gingival and periodontal ligament fibroblasts, and the inhibition of $IL-1{\beta}$ and $PGE_2$ sysnthesis, therefore it is considered that these extracts can be developed as the therapeutics of the periodontal disease.
