  • Currently, both the indirect fluorescent antibody test (IFAT) and enzyme linked immunosorbent assay (ELISA) have been used to detect Neospora caninum antibodies. Several factors such as the buffers, the conjugate, the pattern of fluorescence, and the cross reactivity with other apicornplexan protozoan, may result in poorly correlated data. The present study was undertaken to develop and evaluate the Neospora agglutination test (NAT) for the detection and quantification of IgG antibodies to N. caninum from various animal species. Compared to the ELISA method, the NAT with a cutoff value of 1:512 gave a high index of coincidence (kappa=0.807) and no cross reactivity to Toxoplasma gondii antiserum. Hence, this NAT method, which did not require a species-specific secondary antibody and expensive tools, would be easily available for the detection of antibodies to N. caninllm of various animal species.

  • The purpose of this study was to evaluate the effect of moderate physical exercise program on a number of immune parameters in middle school boys($15.07{\pm}0.39$ yrs). 14 volunteers were included in this physical exercise program. They were randomly assigned to an experiment(7) and a control(7) group. Measurements were taken before program, after 4 weeks and 8 weeks of aerobic exercise for immune parameters such as number of circulating leukocytes, concentration of WEC subsets, lymphocyte subsets, immunoglobulins, complements, and number of blood adipose components. Aerobic exercise consisted of track running at a work intensity of 65% HRmax, $45{\sim}55$ min per day, 3 times per week, and for 8 weeks. The results are as follows; 1. There were no significant changes between and within groups in the number of circulating leukocytes and concentration of WEC subsets. 2. There were significant(p<.05) changes in concentration of B-cell between groups, and T-cell, helper T-cell, and B-cell within experimental group. 3. There were no significant changes between and within groups in concentration of complements. 4. There were significant(p<.05) changes in concentration of IgG between groups and within experimental group. 5. There were significant(p<.05) changes in concentration of TG between groups, and TG, HDL-C and LDL-C within experimental group. In conclusion, the moderate exercise training for 8 weeks can be beneficial on immune function and decrease the concentration of flood adipose components in adolescents.

  • Chemical analysis, measurement of pumping rates of 60 production wells and depth to water tables of 57 monitoring wells were carried to protect depletion of water resources and deterioration of water quality for the commercial portable ground-water. Borehole depth of production well averages 149m(31 boreholes), casing depth is 28m(29 boreholes), production rate is 70 $m^3$/day and depth to water table of monitoring well is 23.26m, respectively. The geology of 60 wells can be divided into Daebo granite(20), Okchun metarmorphic complex(18), Precambrian granitic gneiss(15), Bulguksa granite(4), Cheju volcanics(2), Cretaceous sedimentary rock(1). Average electrical conductivity and pH are 152$\mu$S/cm, and 7.35, respectively. The contents of major cation and anion predominantly $Ca^{2+}$>N $a^{+}$>M $g^{2+}$> $K^{+}$ and HC $O_{3}$$^{-}$ >S $O_{4}$$^{2-}$>Cl ̄>F ̄. Water type is predominantly $Ca^{2+}$-HC $O_{3}$$^{-}$(81.7%). It's possible that water chemistry of some wells were affected not only by the geology of boreholes penetrated but by inflows of surface water or shallow ground-water. Therefore, it is strongly necessary to steadily monitor the water quality and hydrogeologic conditins of production wells.ells.ls.ells.

  • Plasmacytomas are extramedullary accumulations of plasma cells originating from soft tissue. Mediastinal plasmacytoma is a rare presentation. A 67-year-old man recovered after antibiotic treatment for community-acquired pneumonia. However, on convalescent chest radiography after 3 months, mass like lesion at the right lower lung field was newly detected. Follow-up chest computed tomography (CT) revealed an increase in the extent of the right posterior mediastinal mass that we had considered to be pneumonic consolidations on previous CT scans. Through percutaneous needle biopsy, we diagnosed IgG kappa type extramedullary plasmacytoma of the posterior mediastinum.

  • The induction of a phenotype with preoperties may have clinical significance in the acceleration of the wound-healing process. Wound contraction involves a specialized cell known as the myofibroblast. The myofibroblasts can be identified by their intense staining of actin bundles with anti-actin antibody. Tissue-specific actin distribution is correlated with the contractile activity of the myofibroblasts and smooth muscle etc. This study was performed to determine the expression of actin filaments in the cytoplasm of cultured human gingival fibroblsts after GaAs laser(BIOSAER, Korea) irradiation. Human gingival fibroblasts were cultured from explants of normal interdental gingival tissue. The third-generation fibroblasts were used for immunohistochemical study. The cultured fibroblasts were exposed $0.53joule/cm^2$(lmW, 7 mimutes) of energy density, and then observed by immunohistochemical method using, rabbit anti0gelsolin, hen smooth muscle polyclonal antibody(Chemicon international inc.), and biotinylated goat anti-rabbit IgG(Vectastain) 24-, 36-, 48-hour after laser irradiation Following results were obtained ; 1. In nonirradiated cultures, round shaped active fibroblasts with abundant cytoplasm and prominet nucleoli were observed. 2. In 24- and 36-hour cultures after laser irradiation, spindle shaped cells with long process were observed. The intensity of stain was seen in cytoplasm of these modified fibroblasts. 3. In 48-hoour cultures after laser irradiation, stained spindle shape cell were not observed. The results suggest that the effect of the galium-arsenide laser treatment on cultured gingival fibroblasts is the rapid development of cytoplasmic actin filaments.

  • Objectives: Astragalus membranaceus has been reported to inhibit immune responses, but its effect on hair loss is not clear. In this study, the effect of A. membranaceus extract (AM) on hair regrowth in C57BL/6 mice with natural hair loss in the telogen phase was investigated. Methods: Mice with natural hair loss were topically treated with 1% AM on the dorsal skin for 2 weeks. Dorsal skin samples were stained with hematoxylin and eosin and probed with an anti-mouse CD8a IgG. The mRNA expression levels of tumor necrosis factor $(TNF)-{\alpha}$, interferon $(IFN)-{\gamma}$ and interleukin (IL)-4 were measured by reverse transcription polymerase chain reaction and quantitative real-time polymerase chain reaction. Results: AM treatment induced hair regrowth in hair loss mice, while control mice suffered continued hair loss. Tapering hair shafts and broken hair follicles were decreased as well as CD8+ T lymphocyte infiltration. In addition, the expressions of $TNF-{\alpha}$, $IFN-{\gamma}$ and IL-4 were reduced by AM treatment. Also, AM treatment significantly increased the KGF expressions in Hs68 fibroblast cells. Conclusion: These results suggest that topical application of A. membranaceus may be an alternative therapy for hair loss.

  • Neospora caninum is the etiologic agent of bovine neosporosis, which affects the reproductive performance of cattle worldwide. The transmembrane protein, NcSRS2, and dense-granule protein, NcGRA7, were identified as protective antigens based on their ability to induce significant protective immune responses in murine neosporosis models. In the current study, NcSRS2 and NcGRA7 genes were spliced by overlap-extension PCR in a recombinant adenovirus termed Ad5-NcSRS2-NcGRA 7, expressing the NcSRS2-NcGRA7 gene, and the efficacy was evaluated in mice. The results showed that the titer of the recombinant adenovirus was $10^9TCID_{50}/ml$. Three weeks post-boost immunization (w.p.b.i.), the IgG antibody titer in sera was as high as 1:4,096. IFN-${\gamma}$ and IL-4 levels were significantly different from the control group (P<0.01). This research established a solid foundation for the development of a recombinant adenovirus vaccine against bovine N. caninum.

  • Egg allergy has been shown to be the most common food allergy in children with atopic dermatitis. Allergic reactions to proteins derived from egg white (EW) are more common than those derived from egg yolk. Ovomucoid, ovalbumin, ovotransferrin, and lysozyme have been identified as major allergens in EW. This study was conducted to evaluate the effect of EW on immune modulation in an induced allergy mouse model. A total of 50 five-week-old BALB/c male mice were treated with trimellitic anhydride (TMA) for three weeks to induce allergy-like symptoms. The TMA-treated mice were rested for one week and then divided into five groups and fed 0, 10, 50, and 100 mg/d EW for four weeks. All EW consumption groups showed no significant increase or decrease in the populations of white blood cells; however, a significant increase in B-lymphocyte activity was observed in the fourth week. Furthermore, EW consumption did not influence serum immunoglobulin G and immunoglobulin E levels. Taken together, these data demonstrate that the consumption of EW by TMA-treated mice did not increase allergic parameters such as serum IgE level, but enhanced the lymphocyte activities against pathogens. Therefore, this study suggests that the consumption of EW promotes Th2 immune modulation, and EW could be an excellent candidate for maintaining health.

  • Antiphospholipid antibody syndrome(APS) is a well-known clinical syndrome characterized by recurrent arterial or venous thromboses, recurrent fetal loss, thrombocytopenia, together with high titers of sustained anticardiolipin antibody(aCL) or lupus anticoagulant(LA). Although systemic lupus erythematosus(SLB) and APS may coexist, a high proportion of patients manifesting the APS do not suffer from classical lupus or other connective tissue disease. The patient has been defined as having a primary antiphospholipid antibody syndrome. We experienced one case of primary APS with recurrent fetal loss, recurrent cerebral infarctions, positive anticardiolipin antibody IgG and fluttering vegetation on the mitral valve, without other connective tissue diseases including SLE. Forty-three old female had 2 out of 11 criteria for the diagnosis of SLE, such as thrombocytopenia and positive antinuclear antibody, but did not meet whole criteria. The patient was treated with ticlopidine, and anticoagulant therapy was recommended.

  • A layer experiment was conducted to determine the effects of supplementary methionine chelates (Cu, Zn and Mn), individual or in combination, on laying performance, eggshell quality, gizzard erosion, and IgG level of serum for 8 weeks. Five hundred 96-wk-old force molted ISA Brown layers were assigned to five dietary treatments. Basal diet was formulated to meet or exceed the nutrients requirements listed in NRC (1994). Five experimental diets were control, Zn-methionine chelate (Zn-Met) supplemented, Cumethionine chelate (Cu-Met) supplemented, Zn-Mn-methionine chelate (Zn-Mn-Met) supplemented and Zn-Mn-Cu-Met supplemented diet. Each treated diet was supplemented with respective mineral(s) at the level of 100 ppm in the form of methionine chelate. Egg production was increased by Cu-Met supplementation but decreased by Zn-Met supplementation. Egg weight was significantly (p<0.05) lower in Cu-Met treatment than those of the control and Zn-Met treatment. Specific gravity of eggs and eggshell strength were highest and soft egg production was lowest in Cu-Met treatment. Gizzard erosion index was significantly increased by supplementation of Cu-Met, Zn-Mn-Met or Zn-Mn-Cu-Met. Zinc content in liver significantly increased by Zn-Met, but not by Zn-Mn-Cu-Met treatment. In conclusion, 100 ppm Cu in Cu-Met chelate improved laying performance and eggshell quality but also increased gizzard erosion index. Supplementation of Zn-Met or its combination with other mineral chelates had no beneficial effects on laying performance and eggshell quality.
