RESUMO

Background@#Disruptions of the intestinal epithelial barrier (IEB) are frequently observed in various digestive diseases, including irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). This study assessed the improvement in the IEB during the laxative activity of phlorotannin (Pt) harvested from Ecklonia cava in constipation by examining the changes in the expression of the regulatory proteins for the tight junction (TJ) and adherens junction (AJ), and inflammatory cytokines in Sprague Dawley (SD) rats with loperamide (Lm)-induced constipation after a Pt treatment. @*Results@#The Pt treatment induced laxative activity, including the improvement of feces-related parameters, gastrointestinal transit rate, and histological structure of the mid colon in Lm-treated SD rats. In addition, significant recovery effects were detected in the histology of IEB, including the mucus layer, epithelial cells, and lamina propria in the midcolon of Lm + Pt treated SD rats. The expression levels of E-cadherin and p120-catenin for AJ and the ZO-1, occludin, and Claudin-1 genes for TJ in epithelial cells were improved remarkably after the Pt treatment, but the rate of increase was different. Furthermore, the Pt treatment increased the expression level of several inflammatory cytokines, such asTNF-α, IL-6, IL-1β, IL-13, and IL-4 in Lm + Pt treated SD rats. @*Conclusions@#These results provide the first evidence that the laxative activity of Pt in SD rats with Lm-induced constipation phenotypes involve improvements in the IEB.

RESUMO

BACKGROUND: The purpose of this study was to investigate the determinants of North Korean refugees' trust in South Korea health service. METHODS: This study surveyed 168 North Korean refugees aged 19 and over living in Seoul, Gyeonggi, Incheon, and Gangwon. The collected data were analyzed by frequency analysis, t-test, analysis of variance, and hierarchical regression analysis to analyze the effect on the trust of refugees. RESULTS: The difference analysis showed statistically significant difference according to duration of residence and employment status. The determinants of North Korean refugees' trust in South Korea health services were duration of residence, basic communication skills, health communication skills, and experience of health service. CONCLUSION: In order to increase the trust of North Korean defectors in South Korea medical services, it is necessary to resolve communication problems and improve the satisfaction of health services. For this, the interpreter service should be activated. And specific education should be given to the North Korean refugees about the health care system and the utilization methods of health service in Korea.

RESUMO

PURPOSE: This study was to identify international classification of functioning, disability and health (ICF) categories that could be linked conceptually to disability of arm, shoulder and hand (DASH) items and short form of health survey 36 (SF-36) items for persons with shoulder pain. METHODS: Linkage between each item in DASH and SF-36 and the categories in the ICF were assessed. The linking process was performed by ten health professionals following the linking rule. One hundred four patients with shoulder pain were enrolled from 12 private clinic outpatient departments and participated in this study. Pearson correlation coefficients were used to assess the relationships between each scale item and the linked ICF code. RESULTS: Thirty DASH items were able to be linked to 30 ICF codes, whereas the 36 items in SF-36 were only linked to 17 ICF codes. General health items included in SF-36 could not be linked to a relevant ICF concept. There was a high correlation between the two measurement tools and the linked ICF codes, DASH and its ICF code list (r=0.91), SF-36-Physical Health and its code list (r=−0.62), and SF-36-Mental Health and its code list (r=−0.72). CONCLUSION: The results suggest that concepts within each item in DASH can be linked to ICF codes for patients with shoulder pain, however, the concepts in the SF-36 items had limited linkage to ICF codes. The shoulder-specific functional tool, DASH can be expressed with ICF codes and, therefore, its use can promote data standardization and improve communication between professionals.

RESUMO

PURPOSE: This study was to conduct a Korean cultural adaptation of the WHO disability assessment schedule (WHODAS) 2.0: 36-item version. METHODS: An internationally standardized process of translation and cultural adaptation of an instrument was used to develop a Korean version of WHODAS 2.0: 36-item version. Linking each item into the international classification of functioning, disability and health (ICF) was also conducted in order to ensure the concepts in the translated instrument were compatible with ICF. All translated versions of the instrument, linking results and feedback from participants were used for the final adaptation of the Korean version of the instrument. The Korean version of the instrument was assessed twice on different occasions to examine inter- and intra-rater reliability, and the intra-class correlation coefficient (ICC) was calculated. RESULTS: Twelve participants were involved in the translation and linking process. Ninety-five volunteers were invited to participate to examine the reliability of the instrument. Fifty participants completed the self-rated version of the instrument and 45 finished the interviewer version. The Korean WHODAS 2.0: 36-item version was found to have excellent reliability: self-rated version and interviewer version reliability coefficients were ICC=0.92 and ICC=0.94, respectively. Thirty-four items of the translated instrument were to be linked to ICF categories. Some adaptation was made; details and a familiar example were added to help respondents answer the questions. CONCLUSION: The study results show that the adaptation of the 36-item version of WHODAS 2.0 to Korean was successful and the instrument is ready for use in testing its psychometric properties.

RESUMO

Fimasartan, a new angiotensin II receptor antagonist, reduces myocyte damage and stabilizes atherosclerotic plaque through its anti-inflammatory effect in animal studies. We investigated the protective effects of pretreatment with fimasartan on ischemia-reperfusion injury (IRI) in a mouse model of ischemic renal damage. C57BL/6 mice were pretreated with or without 5 (IR-F5) or 10 (IR-F10) mg/kg/day fimasartan for 3 days. Renal ischemia was induced by clamping bilateral renal vascular pedicles for 30 min. Histology, pro-inflammatory cytokines, and apoptosis assays were evaluated 24 h after IRI. Compared to the untreated group, blood urea nitrogen and serum creatinine levels were significantly lower in the IR-F10 group. IR-F10 kidneys showed less tubular necrosis and interstitial fibrosis than untreated kidneys. The expression of F4/80, a macrophage infiltration marker, and tumor necrosis factor (TNF)-α, decreased in the IR-F10 group. High-dose fimasartan treatment attenuated the upregulation of TNF-α, interleukin (IL)-1β, and IL-6 in ischemic kidneys. Fewer TUNEL positive cells were observed in IR-F10 compared to control mice. Fimasartan caused a significant decrease in caspase-3 activity and the level of Bax, and increased the Bcl-2 level. Fimasartan preserved renal function and tubular architecture from IRI in a mouse ischemic renal injury model. Fimasartan also attenuated upregulation of inflammatory cytokines and decreased apoptosis of renal tubular cells. Our results suggest that fimasartan inhibited the process of tubular injury by preventing apoptosis induced by the inflammatory pathway.

RESUMO

BACKGROUND: This study was to investigate the effect of biomechanical stimulation on osteoblast differentiation of human periosteal-derived stem cell using the newly developed bioreactor. METHODS: Human periosteal-derived stem cells were harvested from the mandible during the extraction of an impacted third molar. Using the new bioreactor, 4% cyclic equibiaxial tension force (0.5 Hz) was applied for 2 and 8 h on the stem cells and cultured for 3, 7, and 14 days on the osteogenic medium. Biochemical changes of the osteoblasts after the biomechanical stimulation were investigated. No treatment group was referred to as control group. RESULTS: Alkaline phosphatase (ALP) activity and ALP messenger RNA (mRNA) expression level were higher in the strain group than those in the control group. The osteocalcin and osteonectin mRNA expressions were higher in the strain group compared to those in the control group on days 7 and 14. The vascular endothelial growth factor (VEGF) mRNA expression was higher in the strain group in comparison to that in the control group. Concentration of alizarin red S corresponding to calcium content was higher in the strain group than in the control group. CONCLUSIONS: The study suggests that cyclic tension force could influence the osteoblast differentiation of periosteal-derived stem cells under optimal stimulation condition and the force could be applicable for tissue engineering.

RESUMO

BACKGROUND: Atrial fibrillation (AF) is the most common arrhythmia particularly in the elderly and a potent risk factor for ischemic stroke. Screening for AF in asymptomatic individuals might prevent strokes by earlier detection and anticoagulation therapy. We investigated the prevalence of AF in the Korean elderly and its clinical characteristics. METHODS: This study included 1,483 participants (839 males, 644 females) ≥60 years (72.9±5.4 years) who had undergone electrocardiogram (ECG) screening at the senior health promotion center, Gwangju, from March 2014 to June 2014. Their assessments included 12 lead electrocardiograms, questionnaires and physical examinations. RESULTS: AF was detected in 46 individuals (3.1%), and newly detected in 20 of these 46 (43.4%). The prevalence of AF increased sharply with age-1.0% in 60-69 years group, 3.3% in 70-79 years group, and 7.2% in ≥80 years group. Multivariate logistic regression analysis showed that age (odds ratio [OR], 1.11; 95% confidence interval [CI], 1.05-1.17; p25kg/m2) (OR, 2.17; 95% CI, 1.14-4.11; p=0.017), and heart failure (OR, 8.74; 95% CI, 1.45-52.46, p=0.018) were associated with increased risk for AF. CONCLUSION: The prevalence of AF in the Korean elderly was 3.1% and increased steeply with age from 1.0% to 7.2%. Screening with ECG may be considered as nearly half (43.4%) of AF cases were newly detected.

RESUMO

BACKGROUND/AIMS: The prevalence of hepatitis C virus (HCV) infection in Busan, Gyeongnam, and Jeonnam Provinces in Korea is more than twice the national average. This study aimed to examine whether demographic and lifestyle characteristics are associated with HCV infection in these areas. METHODS: A case control study was performed at three study hospitals. HCV cases were matched with two controls for sex and age. Patient controls were selected from non-HCV patients at the same hospital. Healthy controls were subjects participating in medical checkups. Conditional logistic regression models were used. RESULTS: A total of 234 matched-case and patient- and healthy-control pairs were analyzed. The significant risk factors for both controls were sharing razors (adjusted odds ratio [aOR], 2.39 and 3.29, respectively) and having more than four lifetime sexual partners (aOR, 2.15 and 6.89, respectively). Contact dockworkers (aOR, 1.91) and tattoos (aOR, 2.20) were significant risk factors for the patient controls. Transfusion (aOR, 5.38), a bloody operation (aOR, 5.02), acupuncture (aOR, 2.08), and piercing (aOR, 5.95) were significant risk factors for the healthy controls. Needle stick injuries and intravenous drug abuse were significant in the univariate analysis. CONCLUSIONS: More education concerning the dangers of sharing razors, tattoos and piercings is required to prevent HCV infection. More attention should be paid to needle stick injuries in hospitals and the community.

RESUMO

<p><b>OBJECTIVE</b>To investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).</p><p><b>METHODS</b>We reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.</p><p><b>RESULTS</b>The patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.</p><p><b>CONCLUSION</b>UMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.</p>

RESUMO

ABSTRACT Effects of leached amylose (AM) and amylopectin (AP) on textural and morphological properties of cooked rice were investigated separately by replacing cooking liquid with AM and AP separated from pouring cooking liquid. The pouring of cooking water reduced the hardness (from 28.45 to 19.42N) and stickiness (from 1.74 to 1.19N·s) significantly. However, the addition of AM and AP enhanced the hardness (27.63N) and stickiness (1.71N·s).Scanning electron microscopy show that the leached short-chain AM entered the surface hollows in the cooked rice after water evaporation. Meanwhile, the Long-chain AM cross-linked to formed a three-dimensional network structures, which covered on the filled hollows. This distribution led to a harder texture of cooked rice. The leached AP absorbed water and swelledto form masses. Atthe gelatinization temperature,theAPmassesagglomeratedtoformafilmlayer,whichcoveredtheunevenstructure, the thicker and smoother film contributed to the sticky texture.

RESUMO

An ectopic opening of the common bile duct (CBD) into the duodenal bulb is a very rare congenital anomaly of the biliary system, which may cause recurrent duodenal ulcer or biliary diseases such as choledocholithiasis and cholangitis. Endoscopic retrograde cholangiopancreatography (ERCP) plays a major role in the diagnosis of this anomaly. We report two such cases: one in a 61-year-old man and the other in a 57-year-old man. In the first case, this anomaly caused acute cholangitis with multiple CBD stones, which were successfully treated by ERCP. In the second case, abdominal computed tomography showed pneumobilia, which was further evaluated using ERCP. Besides, this patient was diagnosed with an ectopic opening of the CBD associated with gallbladder cancer. We report these unusual cases and review the relevant medical literature.

RESUMO

BACKGROUND/AIMS: This study compared the prevalence of hepatitis C virus (HCV) infection in the Republic of Korea and estimated the high-risk regions and towns. METHODS: National Health Insurance Service data for 8 years from 2005 to 2012 were used. The subjects of the study had visited medical facilities and been diagnosed with or received treatment for acute or chronic HCV as a primary or secondary disease according to ICD-10 codes of B17.1 or B18.2, respectively. Any patient who received treatment for the same disease multiple times during 1 year was counted as one patient in that year. To correct for the effect of the age structure of the population by year and region, the age-adjusted prevalence was calculated using the direct method based on the registered population in 2010. RESULTS: The overall prevalence of HCV infection among Korean adults (>20 years old) increased from 0.14% in 2005 to 0.18% in 2012. The sex-, age-, and region-adjusted prevalence in 2012 was 0.18%. The prevalence was highest in Busan, Jeonnam, and Gyeongnam, and there were towns with noticeably higher prevalences within these regions: Jindo (0.97%) in Jeonnam, Namhae (0.90%) in Gyeongnam, and Seo-gu (0.86%) in Busan. CONCLUSIONS: The prevalence of HCV infection differs by regions as well as towns in the Republic of Korea, and is highest in Busan, Jeonnam, and Gyeongnam. The reasons for the high prevalence in these specific regions should be identified, since this could help prevent HCV infections in the future. In addition, active surveillance and treatment policies should be introduced to stop any further spread of infection in these high-prevalence regions.

RESUMO

<p><b>OBJECTIVE</b>To investigate the expression of zinc finger E-box binding homebox 1 (ZEB1) in the prepuce of hypospadias children and its relationship to the incidence of hypospadias.</p><p><b>METHODS</b>Prepuce tissues were collected from 37 children aged 6-15 months undergoing hypospadias repair and 11 age-matched controls receiving circumcision. Based on the position of the urethral meatus, the hypospadias cases were classified as severe (n = 13) and mild-moderate (n = 24). The mRNA and protein expressions of ZEB1 were determined by immunohistochemistry and RT-PCR.</p><p><b>RESULTS</b>The expression of the ZEB1 protein was remarkably higher in the severe (100% [13/13]) and mild-moderate hypospadias patients (75.0% [18/24]) than in the controls (9.1% [1/11]), with statistically significant differences between any two groups (P < 0.05). RT-PCR showed the integrated density value (IDV) of the ZEB1 mRNA expression to be (0.67 ± 0.21), (0.81 ± 0.24), and (1.55 ± 0.29) in the control, mild-moderate, and severe hypospadias patients, respectively, significantly higher in the severe hypospadias than in the control and mild-moderate hypospadias groups (P < 0.05), but with no significant difference between the latter two (P = 0.64).</p><p><b>CONCLUSION</b>The expression of ZEB1 is significantly increased in hypospadias patients, and its upregulation is positively correlated with the severity of hypospadias, which suggests that the overexpression of ZEB1 may contribute to the development of hypospadias.</p>

RESUMO

The fungal genus Suillus Micheli ex S. F. Gray plays important roles in the survival and growth of plant seedlings. Humans have utilized these ectomycorrhizal fungi to enhance the nutrient uptake and defense systems of plants, particularly in the reforestation of coniferous forests. The genus Suillus is easily distinguishable by its distinctive morphological features, although the morphology of the fruiting body does not facilitate reliable interspecies discrimination. On the basis of micro-morphological features and internal transcribed spacer sequence analysis, we found that 51 of 117 Korean Suillus specimens had initially been misidentified. The list of the 12 Suillus species previously recorded in Korea was re-evaluated and revised to only eight distinct species: S. americanus, S. bovinus, S. granulatus, S. grevillei, S. luteus, S. pictus, S. placidus, and S. viscidus. We provide taxonomical descriptions for six of these species from the sample specimens.

RESUMO

Hypereosinophilia is often associated with eosinphilic infiltration of tissue, which can lead to severe and irreversible organ damage. One of the most characteristic and critical complications is development of thrombosis in cardiac ventricles, and occasionally in deep veins. We report a rare case of hypereosinophilia, with peripheral vascular thrombosis, caused by Toxocara canis infection.
