It has been reported that injection of Freund's complete adjuvant (FCA) into the hindpaw of a rat induces inflammatory responses with accompanying pain behaviors. Signs of pain behaviors observed in FCA-injected animals were reported to be similar to symptoms seen in patients with inflammatory pain. The nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) is a selective histochemical marker for the nitric oxide synthesizing enzyme, nitric oxide synthase (NOS). N (G)-nitro-L-arginine methyl ester (L-NAME) is a NOS inhibitor. In the present study, we examined if inflammaory pain causes increases in NADPH-diaphorase reactivities in neurons of the dorsal root ganglia (DRG). The results were as follows; 1. FCA-induced inflammation on a limb increased staining density (SD) of NADPH-d positive neurons in the ipsilateral side DRG. 2. Pretreatment of L-NAME did not changed SD of NADPH-d positive neurons on the inflammation of contralateral side DRG 3. Posttreatment of L-NAME decreased the inflammation induced SD of NADPH-d positive neurons. 4. n-NOS immunoreactivity did not match NADPH-d histochemical study, implying the constant level of enzyme itself. Inflammation pain on a hindlimb increased staining density of NADPH-diaphorase positive neuron in the DRG, which was decreased by L-NAME. L-NAME also decreased pain perception. This suggests a role of NO in the pain perception and/or modulation at the level of DRG.

BACKGROUND/AIMS: Angiodysplasia is important in the differential diagnosis of upper gastrointestinal bleeding (UGIB), but the clinical features and outcomes associated with UGIB from angiodysplasia have not been characterized. We aimed to analyze the clinical characteristics and outcomes of angiodysplasia presented as UGIB. METHODS: Between January 2004 and December 2013, a consecutive series of patients admitted with UGIB were retrospectively analyzed. Thirty-five patients with bleeding from angiodysplasia were enrolled. We compared them with an asymptomatic control group (incidental finding of angiodysplasia in health screening, n = 58) and bleeding control group (simultaneous finding of angiodysplasia and peptic ulcer bleeding, n = 28). RESULTS: When patients with UGIB from angiodysplasia were compared with the asymptomatic control group, more frequent rates of nonantral location and large sized lesion (≥ 1 cm) were evident in multivariate analysis. When these patients were compared with the bleeding control group, they were older (mean age: 67.94 ± 9.16 years vs.55.07 ± 13.29 years, p = 0.03) and received less transfusions (p = 0.03). They also had more frequent rate of recurrence (40.0% vs. 20.7%, p = 0.02). CONCLUSIONS: Non-antral location and large lesions (≥ 1 cm) could be risk factors of UGIB of angiodysplasia. UGIB due to angiodysplasia was more common in older patients. Transfusion requirement would be less and a tendency of clinical recurrence might be apparent.

This study was researched to provide the accurate nutrition information and the menu. We questionnaired an recognition and necessity of the nutrition labeling to 684 customers in fast-food restaurants. After data cleaning, we used spss package 14.0 and analyzed about the nutrition contents and place that display the nutrition labeling. First, we finded out lower recognition of nutrition labeling in restaurants than processed food. Second, many people hoped that calory and fat in various nutritions were displayed each 100 g or 100 mL. Third, the place displaying the nutrition information was the menu board and the counter to identify easily. Fourth, we analyzed the recognition and necessity of the nutrition labeling in fast-food restaurants by t-test and ANOVA. So, we knew that the recognition and necessity of the nutrition labeling was higher woman than man. And the more they earn much money and learned, the more the nutrition labeling are needed. But house-wife recognized the nutrition labeling lower than others.

Aspergillus niger has been used as a host to express many heterologous proteins. It has been known that the presence of an abundant protease is a limiting factor to express a heterologous protein. The protease deficient mutant of A. niger was obtained using UV-irradiation. A total of 1x105 spores were irradiated with 10~20% survival dose of UV, 600 J/m2 at 280 nm, and the resulting spores were screened on the casein-gelatin plates. Ten putative protease deficient mutants showing the reduced halo area around colonies were further analyzed to differentiate the protease deficient mutant from other mutant types. Among ten putative mutants, seven mutants showed significant growth defect on nutrient rich medium and two mutants appeared to be the secretory mutants, which resulted in the impaired secretion of extracellular proteins including proteases. A mutant pro--20 showed reduced halo zone without any notable changes in growth rate. In addition, the starch-degrading and glucose oxidase activities in the culture filtrate of pro--20 mutant showed the similar range as that of the parental strain, which suggested that the pro--20 mutant ought to be the protease deficient mutant rather than a secretory mutant. The reduced proteolytic activity of the pro--20 was demonstrated using SDS-fibrin zymography gel. The reduced extracellular proteolysis was quantified by casein degradation assay and, comparing with the parental strain, less than 30% residual extracellular protease activity was detected in the culture filtrate of the pro--20 mutant. The bio-activity of an exogenously supplemented hGM-CSF (human Granulocyte-Macrophage Colony Stimulating Factor) in the culture filtrate of pro--20 mutant was detected until eight times more diluted preparations than that of the parental strain.

Purpose: Mycoplasma pneumoniae pneumonia (MP) is a major cause of community-acquired pneumonia (CAP) in children and is associated with extrapulmonary manifestations (EPM). The incidence and risk factors for EPM in children are unknown. Methods: This was a retrospective study involving 65,243 pediatric patients with CAP between 2010 and 2015 at 23 nationwide hospitals in South Korea. Medical records were reviewed to collect information regarding the clinical characteristics, radiological results, and laboratory findings. Logistic regression with multivariate analysis was performed to evaluate the risk factors associated with EPM in MP. Results: The incidence of EPM was 23.9%, including elevation of liver enzymes (18.1%), mucocutaneous manifestations (4.4%), proteinuria (4.1%), cardiovascular and neurological manifestations (0.4%), hematologic manifestations (0.2%), and arthritis (0.2%). Statistical analysis showed that mucocutaneous manifestations significantly increased with elevated alanine aminotransferase (adjusted odds ratio [aOR], 3.623; 95% confidence interval [CI], 1.933-6.790) and atopic sensitization (aOR, 2.973; 95% CI, 1.615–5.475) and decreased with respiratory virus coinfection (aOR, 0.273; 95% CI, 0.084–0.887). Elevated liver enzymes were significantly associated with elevated lactate dehydrogenase (aOR, 3.055; 95% CI, 2.257–4.137), presence of pleural effusion (aOR, 2.635; 95% CI, 1.767–3.930), and proteinuria with respiratory virus coinfection (aOR, 2.245; 95% CI, 1.113–4.527). Conclusion Approximately 24% of pediatric patients with MP had various EPM. As the risk factors associated with each EPM were different, it is necessary to evaluate the various clinical aspects and findings of MP to predict and prepare for the occurrence of EPM.

PURPOSE: Croup is known to have epidemics in seasonal and biennial trends, and to be strongly associated with epidemics of parainfluenza virus. However, seasonal and annual epidemics of croup have not been clearly reported in Korea. This study aimed to examine the seasonal/annual patterns and etiologies of childhood croup in Korea during a consecutive 6-year period. METHODS: Pediatric croup data were collected from 23 centers in Korea from 1 January 2010 to 31 December 2015. Electronic medical records, including multiplex reverse transcription polymerase chain reaction (RT-PCR) results, demographics and clinical information were cross-sectionally reviewed and analyzed. RESULTS: Overall, 2,598 childhood croup patients requiring hospitalization were identified during the study period. Among them, a total of 927 who underwent RT-PCR were included in the analysis. Males (61.5%) predominated, and most (63.0%) of them were younger than 2 years of age (median, 19 months; interquartile range, 11–31 months). Peak hospitalization occurred in 2010 and 2012 in even-numbered years, and parainfluenza virus (PIV, 39.7%) was the most common cause of childhood croup requiring hospitalization, followed by respiratory syncytial virus (14.9%), human rhinovirus (12.5%), Mycoplasma pneumonaie (10.6%), and human coronavirus (7.3%). CONCLUSION: It is concluded that croup hospitalization has a biennial pattern in even-numbered years. PIV may be the most common cause of childhood croup; however, croup epidemics could be attributed to other viruses.

Background: Atherogenic dyslipidemia, which is frequently associated with type 2 diabetes (T2D) and insulin resistance, contributes to the development of vascular complications. Statin therapy is the primary approach to dyslipidemia management in T2D, however, the role of non-statin therapy remains unclear. Ezetimibe reduces cholesterol burden by inhibiting intestinal cholesterol absorption. Fibrates lower triglyceride levels and increase high-density lipoprotein cholesterol (HDL-C) levels via peroxisome proliferator- activated receptor alpha agonism. Therefore, when combined, these drugs effectively lower non-HDL-C levels. Despite this, few clinical trials have specifically targeted non-HDL-C, and the efficacy of triple combination therapies, including statins, ezetimibe, and fibrates, has yet to be determined. Methods: This is a multicenter, prospective, randomized, open-label, active-comparator controlled trial involving 3,958 eligible participants with T2D, cardiovascular risk factors, and elevated non-HDL-C (≥100 mg/dL). Participants, already on moderate-intensity statins, will be randomly assigned to either Ezefeno (ezetimibe/fenofibrate) addition or statin dose-escalation. The primary end point is the development of a composite of major adverse cardiovascular and diabetic microvascular events over 48 months. Conclusion This trial aims to assess whether combining statins, ezetimibe, and fenofibrate is as effective as, or possibly superior to, statin monotherapy intensification in lowering cardiovascular and microvascular disease risk for patients with T2D. This could propose a novel therapeutic approach for managing dyslipidemia in T2D.
