  • The purpose of this study was to determine the distribution of gram-negative bacteria isolated from companion animals with sepsis, and to investigate the antimicrobial susceptibility patterns of the isolates. Bacterial pathogens were isolated from specimens of dogs and cats submitted to National Veterinary Research and Quarantine Service between 2008 and 2009. A total of 44 gram-negative pathogens were isolated from necropsied organs. The most common isolates were E. coli (n = 33), K. pneumoniae (n = 4) and B. bronchiseptica (n = 4). Most of gram-negative isolates were susceptible to ceftiofur (68.2%), colistin (84.1%), florfenicol (84.1%) and spectinomycin (61.4%). Most of those were resistant to ampicillin (77.3%), erythromycin (86.4%), flumequine (65.9%), lincomycin (97.7%), oxytetracycline (61.4%), penicillin (100%), streptomycin (63.6%), spiramycin (97.7%), sulfamethoxazole (90.9%), tylosin (97.7%) and tiamulin (100%). In conclusion, colistin and florfenicol could be useful against sepsis due to gram-negative bacteria.

  • Parkinson's disease is a neurodegenerative disease caused by damage to brain neurons related to dopamine. Non-clinical animal models mainly used in Parkinson's disease research include drug-induced models of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and 6-hydroxydopamine, and genetically modified transgenic animal models. Parkinson's diagnosis can be made using brain imaging of the substantia nigra-striatal dopamine system and using a radiotracer that specifically binds to the dopamine transporter. In this study, 18F-N-(3-fluoropropyl)-2β-carboxymethoxy-3β-(4-iodophenyl) nortropane was used to confirm the image evaluation cutoff between normal and parkinson's disease models, and to confirm model persistence over time. In addition, the efficacy of single or combined administration of clinically used therapeutic drugs in parkinson's animal models was evaluated. Image analysis was performed using the PMOD software. Converted to standardized uptake value, and analyzed by standardized uptake value ratio by dividing the average value of left striatum by the average value of right striatum obtained by applying positron emission tomography images to the atlas magnetic resonance template. The image cutoff of the normal and the parkinson's disease model was calculated as SUVR=0.829, and it was confirmed that it was maintained during the test period. In the three-drug combination administration group, the right and left striatum showed a high symmetry of more than 0.942 on average and recovered significantly. Images using 18F-N-(3-fluoropropyl)-2β-carboxymethoxy-3β-(4-iodophenyl) nortropane are thought to be able to diagnose and evaluate treatment efficacy of non-clinical Parkinson's disease.

  • Globotriaosylsphingosine (lyso Gb3) is considered as one of the biomarkers for Fabry disease. A rapid and simple UPLC-MS/MS method was developed for the determination of reliable biomarker, lyso Gb3. Total analytical procedure takes only 15 min including sample preparation and MS/MS analysis. Limit of detection was 0.85 ng/ml (S/N=3). The calibration curve was linear over the range of 2.0~400.0 ng/ml ($R^2=0.9999$). Inter-day and intra-day assay accuracy were 93.4~100.6% (RSD, 0.6~6.0%) and 97.5~100.7% (RSD, 3.6~5.2%). Absolute recoveries of 97.6~98.6 showed excellence of a new analytical method. The method was applied to human and mice urines, proved the suitability for the quantification of lyso-Gb3 for screening, diagnosis and therapeutic monitoring of Fabry disease patients.

  • M$\acute{e}$n$\acute{e}$trier's disease is a rare form of acquired gastropathy characterized by giant rugal folds in the stomach and protein-losing gastropathy. Children with M$\acute{e}$n$\acute{e}$trier's disease tend to follow a benign self-limited course with symptoms typically completely resolving within 2 to 10 weeks in contrast to the chronic course in adults. A 9-year-old girl presented with a history of gradually worsening abdominal distension, increasing body weight, and abdominal pain for 2 weeks. Physical examination on admission indicated periorbital swelling, pitting edema in both the legs, and abdominal distension with mild diffuse tenderness and shifting dullness. Laboratory tests on admission showed hypoalbuminemia, hypoproteinemia, and peripheral eosinophilia. The test result for anti-cytomegalovirus immunoglobulin M was negative. Increased fecal alpha 1 anti-trypsin excretion was observed. Radiological findings showed massive ascites and pleural effusion in both the lungs. On gastroscopy, large gastric folds, erythema, erosion, and exudation were noted in the body and fundus of the stomach. Microscopic findings showed infiltration of eosinophils and neutrophils in the gastric mucosa. Her symptoms improved with conservative treatment from day 7 of hospitalization and resolved completely.

  • Objective : Structural genetic variation, including copy-number variation (CNV), constitutes a substantial fraction of total genetic variability, and the importance of structural variants in modulating susceptibility is increasingly being recognized. CNV can change biological function and contribute to pathophysiological conditions of human disease. Its relationship with common, complex human disease in particular is not fully understood. Here, we searched the human genome to identify copy number variants that predispose to moya-moya type cerebrovascular disease. Methods : We retrospectively analyzed patients who had unilateral or bilateral steno-occlusive lesions at the cerebral artery from March, 2007, to September, 2009. For the 20 subjects, including patients with moyamoya type pathologies and three normal healthy controls, we divided the subjects into 4 groups : typical moyamoya (n=6), unilateral moyamoya (n=9), progression unilateral to typical moyamoya (n=2) and non-moyamoya (n=3). Fragmented DNA was hybridized on Human610Quad v1.0 DNA analysis BeadChips (Illumina). Data analysis was performed with GenomeStudio v2009.1, Genotyping 1.1.9, cnvPartition_v2.3.4 software. Overall call rates were more than 99.8%. Results : In total, 1258 CNVs were identified across the whole genome. The average number of CNV was 45.55 per subject (CNV region was 45.4). The gain/loss of CNV was 52/249, having 4.7 fold higher frequencies in loss calls. The total CNV size was 904,657,868, and average size was 993,038. The largest portion of CNVs (613 calls) were 1M-10M in length. Interestingly, significant association between unilateral moyamoya disease (MMD) and progression of unilateral to typical moyamoya was observed. Conclusion : Significant association between unilateral MMD and progression of unilateral to typical moyamoya was observed. The finding was confirmed again with clustering analysis. These data demonstrate that certain CNV associate with moyamoya-type cerebrovascular disease.

  • This study was designed to investigate the correlation between nutrition status and cardiovascular disease in type 2 diabetes patients with metabolic syndrome. The subjects were 66 patients and divided into Non MS (a group without metabolic syndrome, n = 37) and MS (a group with metabolic syndrome, n = 29). The percentage of patients accompanying metabolic syndrome was 43.9% and family history such as DM, skipping meal and eating speed were higher in MS (P < 0.05) The average values of BMI, body fat (%), waist circumference were significantly higher in patients of MS than that of Non MS. For hamatological values, MS showed higher FRS, HOMA-IR, LDL-Cholesterol, CRP. Percentage of FRS was 21.63% in MS that is relatively higher in comparison with 16.81% in Non MS. Moreover, the incidence of cardiovascular disease appeared 13.8% in MS that is higher than 2.7% in Non MS. The intake of sodium and vitamin E were higher, but the intake of fat, vitamin A and zinc were lower in MS than in Non MS. Close correlations were elucidated among FRS, occurrence of cardiovascular disease, weight, waist circumference, Total-Cholesterol, LDLCholesterol, sodium in both groups. In conclusion, cardiovascular disease risk factors would be higher in type 2 diabetes patients with metabolic syndrome and there were distinctive patterns that were associated with hamatological values, nutrition intake risk factors. This result should be considered when designing nutrition study and intervetion programs.

  • Fluoxetine, widely used for the treatment of depression, is known to be a selective serotonin reuptake inhibitor (SSRI), however, there are also reports that fluoxetine has direct effects on several receptors. Employing whole-cell patch clamp techniques in rat brain slice, we studied the effects of fluoxetine on corticostriatal synaptic transmission by measuring the change in spontaneous excitatory postsynaptic currents (sEPSC). Acute treatment of rat brain slice with fluoxetine ($10{\mu}M$) significantly decreased the amplitude of sEPSC ($8.1{\pm}3.3$%, n=7), but did not alter its frequency ($99.1{\pm}4.7$%, n=7). Serotonin ($10{\mu}M$) also significantly decreased the amplitude ($81.2{\pm}3.9$%, n=4) of sEPSC, but did not affect its frequency ($105.8{\pm}8.0$, n=4). The effect of fluoxetine was found to have the same trend as that of serotonin. We also found that the inhibitory effect of fluoxetine on sEPSC amplitude ($93.0{\pm}1.9$%, n=8) was significantly blocked, but not serotonin ($84.3{\pm}1.6$%, n=4), when the brain slice was incubated with p-chloroamphetamine ($10{\mu}M$), which depletes serotonin from the axon terminals and blocks its reuptake. These results suggest that fluoxetine inhibits corticostriatal synaptic transmission through postsynaptic, and that these effects are exerted through both serotonin dependent and independent mechanism.

  • Acute disseminated encephalomyelitis (ADEM) is an inflammatory demyelinating disease of the central nervous system that typically follows an infection or vaccination and has a favorable long-term prognosis. We describe the first reported case of ADEM after vaccination against novel influenza A (H1N1). A previously healthy 34-month-old boy who developed ADEM presented with a seizure and left-sided weakness 5 days after vaccination against novel influenza A (H1N1). Cerebrospinal fluid examination revealed elevated cell counts. T2-weighted images and fluid-attenuated inversion recovery images revealed multiple patchy hyperintense lesions in the frontal and parietal subcortical white matter and the left thalamus. After the administration of intravenous corticosteroid, the patient's clinical symptoms improved and he recovered completely without neurologic sequelae.

  • The content of $N^{\varepsilon}$-(carboxymethyl)lysine (CML), an advanced glycation endproduct, in stir-fried anchovy prepared under different cooking conditions was determined, along with their sensory properties. The aim of the study was to optimize cooking conditions of stir-fried anchovy for minimal CML production by using different sugars, sugar concentrations, pH levels, and cooking times. The results showed that CML content increased with increasing sugar concentration. Cooking time did not affect CML content but lowering the pH with lemon juice decreased it significantly. The CML content of samples with a high sugar concentration, and without lemon juice was $4.67{\mu}g/mL$, and that of samples with both a low sugar concentration and lemon juice was $2.49{\mu}g/mL$, indicating a 47% reduction in the CML content of sir-fried anchovy. We conclude that stir-fried anchovy cooked with less sugar and the addition of lemon juice can reduce CML content while maintaining sensory characteristics.

  • Purpose: To compare the effects of the Interaction Model of Client Health Behavior (IMCHB)-based oral health program (OHP) and walking exercise program (WEP) on oral health behaviors, periodontal disease, physical activity, and psychological indicators (depression, stress, and quality of life) in pregnant women. Methods: A nonequivalent control group pretest-posttest design was adopted to compare the effects of a 12-week OHP and WEP on pregnant women (n=65). Pregnant women were randomly assigned to the oral health group (OHG; n=23), walking exercise group (WEG; n=21), or control group (CG; n=21). Data were analyzed by the ${\chi}^2-test$, Fisher's exact test, Scheffe test, and repeated measures ANOVA, using the Statistical Package for the Social Sciences for Windows (version 21.0). Results: The OHG and WEG showed significant improvements in oral health behaviors, periodontal disease, and psychological indicators as compared to the CG. The WEG showed significant improvement in physical activity as compared to the OHG and CG. Conclusion: These findings indicate that the IMCHB-based OHP and WEP were effective in improving periodontal disease, physical activity, and psychological indicators. However, further studies are needed to identify the positive effects of the OHP and WEP on birth outcomes.
