  • A 52-year-old woman presented with lower back pain, progressive symmetrical paraparesis with sensory impairment, and sphincter disturbance. Magnetic resonance imaging (MRI) of the whole spine revealed multiple intradural extramedullary serpiginous-mass lesions in the subarachnoid space continuously from the prepontine to the anterior part of the medulla oblongata levels, C7, T2-T8, and T12 vertebral levels distally until the end of the theca sac and filling-in the right S1 neural foramen. Sparganosis was diagnosed by demonstration of the sparganum in histopathological sections of surgically resected tissues and also by the presence of serum IgG antibodies by ELISA. DNA was extracted from unstained tissue sections, and a partial fragment of mitochondrial cytochrome c oxidase subunit 1 (cox1) gene was amplified using a primer set specific for Spirometra spp. cox1. After sequencing of the PCR-amplicon and alignment of the nucleotide sequence data, the causative agent was identified as the larva of Spirometra erinaceieuropaei.

  • Force-deformation modelling of cracked reinforced concrete is essential for a displacement-based seismic assessment of structures and can be achieved by fibre-element analysis of the cross-section of the major lateral resisting elements. The non-linear moment curvature relationship obtained from fibre-element analysis takes into account the significant effects of axial pre-compression and contributions by the longitudinal reinforcement. Whilst some specialised analysis packages possess the capability of incorporating fibre-elements into the modelling (e.g., RESPONSE 2000), implementation of the analysis on EXCEL is illustrated in this paper. The outcome of the analysis is the moment-curvature relationship of the wall cross-section, curvature at yield and at damage control limit states specified by the user. Few software platforms can compete with EXCEL in terms of its transparencies, versatility and familiarity to the computer users. The program has the capability of handling arbitrary cross-sections that are without an axis of symmetry. Application of the program is illustrated with examples of typical cross-sections of structural walls. The calculated limiting curvature for the considered cross-sections were used to construct displacement profiles up the height of the wall for comparison with the seismically induced displacement demand.

  • Objectives : This study was designed to investigate therapeutic effects fo NR on allergic asthma in terms of measurement of cytokine profiles, distribution of BAL and expression levels of asthma induced by OVA. Methods : C57BL/6 mouse was divided into normal, NRI, control, and NRII, and Notopterygii Rhizoma Extract was orally administered to the C57BL/6 mice in the normal group and the normal mouse in NRI group while it was orally administered to the control group after inducing asthma by OVA and NRII. The study measured them by means of ELISA after dividing BALF of each group, and analyzed RT-PCR by using lung tissues. Results : In our results, lung weight and the number of total cells in the lung and of Leukocyte and Eosinophils in BALF were significantly decreased. In addition, IL-4, IL-5, IL-13, and IgE in BALF were significantly decreased compared to the control group. Conclusions : These results demonstrate that NR Extract be a desirable altemative therapy for allergic asthma by inhibiting the expressin of immune cells, the activation of inflammatory mediator.

  • This study was performed to investigate the immunopotentiative effects of conjugated linoleic acid on mice immunosuppressed by administratin corticoids. Mice were divided into four groups of 8 mice. Two groups (C, CP) were given diet supplemented with 1% linoleic acid (CLA) and the other two groups (L, LP) were given diet supplemented with 1% linoleic acid (LA) instead of CLA. Prednison was administered to two groups (CP, LP) for immune depression. After feeding diets for 3 weeks containing PDS injection for last 1 week. Serum and gut lumen lavage were taken. Measurement of total Ig were executed using sandwich ELISA. Serum levels of IgA, IgG, and IgM showed some trend which groups fed with CLA were higher than groups fed with LA while IgE was reduced in those fed the CLA intake, and groups administered with PDS were lower than groups administered with saline. However, no significant differences were seen in the proportion of total immunoglobulin in serum. In case of secretory IgA, Group C and CP were significantly higher than group L and LP. Especially between CP and LP, it can be seen effects of CLA. In addition that the CLA treated group weighted a significantly lower level than the one's that have not been treated with CLA. These result support the view that CLA potentiate the immune response and prevent immune depression caused by administrating of corticoids. In conclusion, CLA produced a situation favorable for immunopotentiative effects. Thus, the clinical application of CLA is warranted.

  • Chlorogenic acid is a phenolic compound found in Cudrania tricuspidata fruits. In the present study, the effect of chlorogenic acid on the inhibition of adipogenesis in 3T3-L1 adipocytes was investigated. Cells were stained with Oil red O reagent to detect lipid droplets in adipocytes. The 3T3-L1 cells were lysed and measured for intracellular triglyceride and adipokine by ELISA kit. The protein expression of adipogenesis-related gene was evaluated by Western blot analysis. Chlorogenic suppressed lipid droplet and intracellular triglyceride accumulation in a concentration manner and also decreased secretion of adipokines such as leptin and adiponectin, compared with fully differentiated adipocytes. Treatment of 3T3-L1 cells with chlorogenic acid reduced the protein levels of peroxisome proliferator-activated receptor gamma ($PPAR{\gamma}$) and, CCAAT/enhancer binding proteins alpha ($C/EBP{\alpha}$). This indicates that chlrogenic acid was effective as an anti-obesity agent by repressing the differentiation of 3T3-L1 into adipocytes and inhibiting triglyceridef formation in adipocyte and that it exerts its role mainly through the significant down-regulation of $PPAR{\gamma}$ and $C/EBP{\alpha}$.

  • We examined the immunological properties of the recombinant hepatitis B surface antigen (r-HBsAg) which was expressed in mammalian cell (C127). The cross-immunity of r-HBsAg and plasma-derived hepatitis B surface antigen (p-HBsAg) were tested using Western blotting and ELISA with guinea pig polyclonal antibody and naturally infected human-derived antibody and the both antigens show the same results in their response pattern and intensity, which indicate they have a good cross-immunity. from the measurement of $ED_{50}$ after formalin- or heat-inactivation, both r-HBsAg and p-HBsAg and p-HBsAg showed $ED_{50}$ of 0.2-0.3 in formalin-inactivaton, while r-HBsAg was 0.05-0.09 and p-HBsAg was 0.03-0.07 in heat-inactivation, which means heat-inactivation method is 3-4 times superior in immunogenicity. In the immunopersistency test performed in guinea pig for the period of 3 months with two different adjuvants, antibody titer was 34.2 with muramyl dipeptide adjuvant, which was 1.8 times greater than the antibody titer of 18.9 with $AIPO_{4}$ adjuvant. the mutagenicity of r-HBsAg has the same cross-immunity with p-HBsAg, and heat-inactivation method and muramyl dipeptide adjuvant allow development of r-HBsAg vaccine with excellent immunogenicity.

  • In order to investigate the effects of bisphenol A (BPA) on cell mediated immune reaction in vitro we examined the allogenic mixed lymphocyte reaction (MLR), splenocytes proliferation (SP) to T cell mitogens and IFN-${\gamma}\;production$. Splenocytes of Balb/c mice ($1.5{\times}10^5$ cells/well) were co-cultured with different numbers of mitomycin C-treated mature dentritic cells (DCs) in presence of BPA (25, 50, 100 ${\mu}M$) and $[^{3}H]$thymidine incorporation (cpm) was measured by scintilation counting. Splenocytes ($2{\times}10^6$ cells/well) were cultured with mitogens, Con A ($2\;{\mu}g/ml$), PHA ($5\;{\mu}g/ml$) and IL-2 ($0.1\;{\mu}g/ml$), or PMA ($5\;{\mu}g/ml$) and INO ($1\;{\mu}g/ml$) in presence of BPA (1, 10, 25, 50, 100 ${\mu}M$) and SP was assessed by MTT assay. $IFN-{\gamma}$ levels in culture supernant were determined by ELISA. At low concentration, BPA slightly increased MLR, SP and $IFN-{\gamma}$ levels, but at higher concentration it showed significant inhibitory effects on these immunological parameters. These results indicate that BPA is able to alternate cell-mediated immune reaction.

  • A simple, rapid, specific and sensitive method for the detection of serum hepatitis C virus (HCV) RNA using the reverse transcription-polymerase chain reaction (RT-PCR) technique without conventional RNA extraction was developed. HCV template RNA from serum was obtained by boiling the serum at $95^{\circ}C$ for 2 min, cooling rapidly in ice and removing the proteins by cetrifugation. RT-PCR amplifications including the reverse transcription and first PCR amplification were performed in one vessel containing both of reverse transcriptase and Taq DNA polymerase. The detection of HCV RNA from $10^{-3}{\mu}l$. serum was possible with this method. The suitability of this method for clinical analysis was evaluated by assaying HCV RNA in 225 patient samples including anti-HCV antibody negatives (13 samples) and positives (212 samples) by enzyme-linked immunosorbent assay test (ELISA). Detections of HCV RNA with this method were in 4 of 13 anti-HCV antibody negative samples (30.8%) and 95 of 212 positive samples (44.8%). The present method can be completed in 1 hr and has a wide range of application for the clinical utilities to determine the viral RNAS.

  • A series of 3-(substituted-benylidene)-1, 3-dihydro- indolin-2-one, 3-(substituted-benylidene)-1, 3-dihydro- indolin-2-thione and 2, 2'-dithiobis 3-(substituted-benylidene)-1, 3-dihydro-indole derivatives was investigated as inhibitor of $p60^{c-Src}$tyrosine kinase by performing receptor docking studies and inhibitory activity toward tyrosine phosphorylation. Some compounds were shown to be docked at the site, where the selective inhibitor PP1 [1-tert-Butyl-3-p-tolyl-1H-pyrazolo[3,4-d]pyrimidine-4-yl-amine] was embedded at the enzyme active site. Evaluation of all compounds for the interactions with the parameters of lowest binding energy levels, capability of hydrogen bond formations and superimposibility on enzyme active site by docking studies, it can be assumed that 3-(substituted-benzylidene)-1, 3-dihydro-indolin-2-one and thione derivatives have better interaction with enzyme active site then 2, 2'-dithiobis 3-(substituted-benzylidene)-1, 3-dihydro indole derivatives. The test results for the inhibitory activity against tyrosine kinase by Elisa method revealed that 3-(substituted-benylidene)-1, 3-dihydro- indolin-2-thione derivatives have more activity then 3-(substituted-benylidene)-1, 3-dihydro- indolin-2-one derivatives.
