Yersinia (Y.) ruckeri has been recognized as a serious bacterial pathogen to several kinds of fish, including rainbow trout. However, there are no reports about the characteristics and pathogenicity of Y. ruckeri isolated from farm-cultured eels. In this study, we isolated and characterized Y. ruckeri from the farm-cultured eel Anguilla japonica in Korea. We investigated the phenotypic and genotypic characteristics of Y. ruckeri and tested the virulence of Y. ruckeri isolates on experimentally infected eels. Examination of the flagellar morphology of Y. ruckeri by electron microscopy showed peritrichous flagella in its cell body. Biochemical reaction studies showed overall identical profiles between the isolates and the reference strain of Y. ruckeri in API 20E and API ZYM tests. We sequenced the 16S rRNA of the Y. ruckeri (1,505 bp) for the genotypic characterization (National Center for Biotechnology Information accession number EU401667). Comparison of the 16S rRNA sequences with previously reported Y. ruckeri strains revealed similar phylogenetic relationships. In the virulence assay of the Y. ruckeri on eels, the eels exhibited listlessness, but Y. ruckeri was reisolated from those of the gills and kidneys.

Background: Compared with other chronic diseases, hearing loss is generally overlooked from the perspective of disease burden. However, hearing loss is emerging as an important issue in the current society. The objective of this study was to investigate disease burdens and marginal utilities associated with hearing loss and other chronic diseases. Methods: This study analyzed the cross-sectional data of 32,986 participants aged 19 years and older who completed the Korea National Health and Nutrition Examination Surveys between 2009 and 2013. Additionally, this study used the pure tone audiometric test, European Quality of Life-Five Dimensions Questionnaire, and chronic disease status. The data were analyzed using a multiple linear regression method. Results: The data of 23,297 people who underwent a pure tone audiogram and completed the European Quality of Life-Five Dimensions Questionnaire were used in this analysis. The marginal utility of hearing loss ranked fifth among nine chronic diseases. The estimated loss of quality-adjusted life years associated with hearing loss was -93.69 years per 100,000 people, which is similar to other chronic diseases. Conclusion: This study assessed the marginal utilities and public burdens of hearing loss and eight chronic diseases in a South Korean population. Although the values may vary depending on country and race, this study may provide an indispensable foundation for more detailed studies on hearing loss.
Objectives : To research the trend of the study related to pharmacopuncture about musculoskeletal and nervous diseases in China and to make a comparison with clinical application on pharmacopuncture about musculoskeletal and nervous diseases in China and Korea. Methods : I reviewed and analyzed four Chinese Journals relating pharmacopucture from 2004 to 2008 and two Korean Journals relating pharmacopuncture from 1999 to 2008. Results : The following results were obtained in this study. 1. The pharmacopuncture was often used for diseases of spines and joints. 2. In the medicine of pharmacopuncture, Salviae Miltiorrhizae Radix, Angelicae Gigantis Radix were mainly used in China, and Bee-venom in Korea. 3. As a method of needling, local acupoint and Ashi-point were mainly ueed in both China and Korea. 4. In combined treatments, acupuncture, electronic acupuncture, Chuna, heating acupuncture were mainly used in China, and acupuncture, herb medicine, physiotherapy in Korea. 5. In the case of control group study, compared with other treatments pharmacopuncture was not verified the superiority of effectiveness in China, but in Korea, the effectiveness of a pharmacopuncture could be compared with that of others and the effectivenss of different pharmacopuncture could be compared. Conclusions : As seen above, in Korea, clinician should carry out clinical application about musculoskeletal and nervous diseases with various herbal injections besides Bee-venom. And I think that it will be starting point to use Salviae Miltiorrhizae Radix and Angelicae Gigantis Radix that were often used in China.

Objectives: This study aimed to investigate the current status of infectious disease research in North Korea by analyzing recent trends in medical journals from North Korea in comparison with research from South Korea. Methods: Three medical journals (Preventive Medicine, Basic Medicine, and Chosun Medicine) were analyzed from 2012 to 2016. Articles on tuberculosis (TB), malaria, and parasitic diseases were selected and classified by their subtopics and study areas. Two medical journals published in the South Korea were selected for a comparative analysis of research trends. Results: Of the 2792 articles that were reviewed, 93 were extracted from North Korea journals. TB research in North Korea was largely focused on multi-drug resistant TB and extrapulmonary TB, whereas research in South Korea more frequently investigated non-tuberculous mycobacteria. Research on parasitic diseases in North Korea was focused on protozoan and intestinal nematodes, while the corresponding South Korea research investigated various species of parasites. Additionally, the studies conducted in North Korea were more likely to investigate the application of traditional medicine to diagnosis and treatment than those conducted in South Korea. Conclusions: This study presents an analysis of research trends in preventive medicine in North Korea focusing on infectious diseases, in which clear differences were observed between South and North Korea. Trends in research topics suggest a high prevalence of certain parasitic diseases in North Korea that are no longer widespread in South Korea. The large proportion of studies examining traditional medicine implies a lack of affordable medicine in North Korea.
Purpose: The purpose of this study was to assess the relationship between psychological factors and symptoms of oral mucosal diseases by means of the revised version of the Minnesota Multiphasic Personality Inventory (MMPI-2). Methods: Three hundred and eighteen college students in Gyeonggi-do completed the MMPI-2 and a questionnaire related to symptoms of oral mucosal diseases and collected data were analyzed by Student's t-test and one way ANOVA. Results: Subjects who have experienced herpetic stomatitis revealed significantly higher mean values of T-scores than subjects who have not on hypochondriasis (Hs) and hysteria (Hy) clinical scales of the MMPI-2 (p<0.05). In comparison with subjects who have had recurrent aphthous ulceration, subjects who have not had it manifested significantly higher elevations on the schizophrenia (Sc) clinical scale (p<0.05). Subjects who have suffered oral lichen planus (OLP) showed significantly higher mean values of T-scores than subjects who have not on paranoia (Pa) (p<0.05) and hypomania (Ma) (p<0.01) clinical scales. Mean values of T-scores on Ma clinical scale were significantly higher in subjects having experienced glossodynia than in subjects having not experienced (p<0.05). Subjects having felt taste disturbance exhibited significantly higher elevations on Hs (p<0.0001) and Hy (p<0.01) clinical scales compared to subjects having not. Conclusions: Symptoms of oral mucosal diseases such as herpetic stomatitis, taste disturbance, OLP, and glossodynia were found to be related to Hs, Hy, Pa, Ma clinical scales of the MMPI-2. Therefore, comprehensive psychological evaluations of those oral mucosal diseases may be beneficial in a therapeutic approach.
Purpose: The purpose of this study was to conduct a comparison analysis on requirements of online continuing education requirements according to practical experience of nurses at small and medium-sized hospitals. Methods: Data had been collected with 236 nurses from May to June, 2015. The data were analyzed with the use of SPSS. Results: Among them, 45.8% participated in online continuing education. Nurses in beginning level required musculoskeletal diseases (20.9%), care for injuries and stomas (5.8%), and surgical disease and operation care (4.7%). Competent nurses required musculoskeletal diseases (19.7%), cerebrovascular diseases (9.9%), emergency care and CPR (8.5%), and medical nursing (8.5%). Skillful nurses required cerebrovascular diseases (13.9%), care for internal diseases (8.9%), and rehabilitation care (8.9%). Among the educational contents of diseases, the items that were significantly different according to practical experience were operation management ($x^2$=23.92, p<.001) and drug care ($x^2$=7.85, p=.020). Among continuing education methods, the items that were significantly different were video ($x^2$=16.81, p<.001), webtoon ($x^2$=8.96, p=.011), and test ($x^2$=10.56, p=.005). Among continuing education evaluation methods, the items that were significantly different were multiple-choices ($x^2$=9.43, p=.009) and OX ($x^2$=6.47, p=.039) based quizzes. Conclusion: Based on the study results, it is necessary to develop a differentiated continuing education program according to practical experience of nurses.
BACKGROUND/OBJECTIVES: The elderly are reported to have a high prevalence of nutritional anemia when they have lower intakes of nutrients or chronic diseases. This study was conducted to compare nutritional status according to nutritional anemia and to determine associations between nutritional anemia and chronic diseases in Korean elderly. SUBJECTS/METHODS: This study utilized data on 3,258 elderly aged ${\geq}65$ years gathered during the $6^{th}$ Korea National Health and Nutrition Examination Survey 2013-2015. Subjects were divided into nutritional anemia (NA) group (n = 415) and non-NA group (n = 2,843) by hemoglobin concentration. Nutrient intakes were assessed using dietary intake data obtained using the 24-hour recall method. The odds ratios (ORs) for nutritional anemia by chronic diseases were determined. Statistical analysis was performed using SPSS Ver. 23.0. RESULTS: Of 3,258 subjects, 12.7% had nutritional anemia. Intakes of potatoes, pulses, and mushrooms by males and potatoes, fruits, meats, eggs, and seafood by females were significantly lower in NA group than in non-NA group. The proportion of the subjects whose intakes of protein, vitamin A, vitamin $B_1$, vitamin $B_2$, niacin, and iron less than estimated average requirement (EAR) were significantly higher in NA group compared to non-NA group. After adjusting for age, the number of family members, energy intake, and alcohol drinking, ORs for nutritional anemia in the subjects with diabetes and myocardial infarction or angina pectoris were significantly higher by 1.74 times and 1.59 times as compared to the subjects without those diseases, respectively. However, ORs for nutritional anemia in the subjects with obesity, abdominal obesity, and hypertriglyceridemia were significantly lower by 0.64 times, 0.60 times, and 0.59 times as compared to the subjects without those diseases, respectively. CONCLUSIONS: The results of this study suggested that nutritional management should be done to enable the Korean elderly to consume foods with high hematopoietic nutrients density to prevent nutritional anemia. Korean elderly need to make regular efforts to check for nutritional anemia.
Oral viridans streptococci are recognized as one of the etiological agents of a variety of infectious diseases such as dental caries and infective endocarditis. Although antimicrobial susceptibility tests for these fastidious bacterial species are now established and standardized, a comparison between the broth microdilution and broth macrodilution tests has not previously been performed. This comparison was performed in the present study using the tests adopted by the Clinical and Laboratory Standards Institute (CLSI) and seven clinical isolates of oral viridans streptococcal strains. A modified broth macrodilution susceptibility test method was also included in this analysis, in which the media was not supplemented with horse blood. The susceptibility interpretation category agreements were measured at 83% (broth microdilution versus broth macrodilution) and 71% (broth microdilution versus modified broth macrodilution). The interpretation category agreement between the broth macrodilution and modified broth macrodilution tests was also 83%. These data indicate that the interpretation of antibiotic susceptibility test results for oral viridans streptococci are influenced by the methods used.

The current study is the first paper on FPT(failure of passive transfer) of horse population in Korea. The object of this study was to comparison of immune status normal and patient horses. Failure of passive transfer is the most common immunodeficiency disorder of horses. Twenty-two foals and 18 horses from Jeju of the equine hospital were diagnosed with the SNAP Foal IgG Test Kit. All adult horses had normal immune functions (≥800 mg/dl). Thirteen of the 22 newborn babies (59%; ∠800 mg/dl) had a weak immune function but recovered and survived after treatment. Nine of these 22 are horses with strong immunity (≥800 mg/dl), indicating that high IgG concentrations in the blood can cause infectious diseases. There were a total of six dead, four of which were infectious diseases. In addition, early identification of infectious diseases in newborn foals is expected to help prepare systematic health management measures for the development of the disease.
The worldwide distribution and continuing genetic mutation of avian influenza virus (AIV) has been posed a great threat to human and animal health. A comparison of 3 isolates of AIV H9N2, A/chicken/Korea/KBNP-0028/00 (H9N2) (KBNP-0028), A/chicken/Korea/SNU8011/08 (H9N2) (SNU 8011) and an inactivated oil vaccine strain A/chicken/Korea/01310/01 (H9N2) (01310), was performed. The former 2 AIVs were isolated from field cases before and after the application of an inactivated H9N2 vaccine in 2007, respectively. The antigenic relationship, viral shedding, tissue tropism and genetic analysis were examined. The comparison of virus shedding from the cloaca and the oropharynx revealed that both isolates were more frequently isolated from the upper respiratory tract (90~100%) 1 day post inoculation (DPI) compared with isolation 5 DPI from gastrointestinal tracts (10~60%). Moreover, the isolate KBNP-0028 were recovered from all organs including bone marrow, brain and kidneys, indicating higher ability for broad tissue dissemination than that of SNU 8011. KBNP-0028 replicated earlier than other strains and with a higher titer than SNU 8011. In full-length nucleotide sequences of the NA gene and a partial sequence of the HA gene of SNU 8011, we found that there might be significant changes in tissue tropism, virus replication and genetic mutation in AIV H9N2 isolates.
