A total 49 strains of Escherichia coli suspected of causative organisms of urinary tract infection were isolated and studies for several properties related to the virulence markers of organisms. Urinary isolates (42.9%) showed higher frequency of mannose resistant hemaglutination (MRHA) with human erythrocytes (O type, Rh+) than stool isolates (13.3%) as a control group. Fifteen strains (30.6%) of urinary isolates and 2 (l3.3%) of stool isolates showed hemolysis on blood agar plate. Fourteen strains (28.6%) of urinary isolates and 5 (33.3%) of stool isolates produced colicin. Twelve strains (52.5%) among 23 strains of positive MRHA reaction and 5 (12.2%) of 41 non-MRHA strains found to be hemolytic effect but the frequency of transferable antimicrobial resistance of non MRHA strains was greater than that of MRHA strains. Three properties of hemaglutination, hemolysis, and colicin production were not transferred to recipient E. coli ML 14lO and/or RG 488 by conjugation whereas the antimicrobial resistance were transferred. There was not any significant difference of the minimal inhibitory concentration of 11 drugs between both groups of hemaglutinating and non-hemaglutinating strains. * A thesis submitted to the Committee of the Graduate School of Kyung Pook National University in partial fulfillment of the requirements for the degree of Master of Medical Science in June 1985.

OBJECTIVES: This study was conducted to measure the decline in the health-related quality of life (HRQoL) associated with some diseases in South Korean adults. METHODS: The EQ-5D health states in the 2005 National Health and Nutrition Examination Survey (NHNES) and the Korean EQ-5D valuation set were used to obtain the EQ-5D indexes of the study subjects. Each disease group was defined when the subjects reported to the NHNES that they were diagnosed with the corresponding disease during the previous 1 year by physicians. Since the distributions of the EQ-5D indexes in each subgroup were negatively skewed, median regression analysis was used to estimate the effects of specific diseases on the HRQoL. Median regression analysis produced estimates that approximated the median of the EQ-5D indexes and there are more robust for analyzing data with many outliers. RESULTS: A total of 16,692 subjects (6,667 patients and 10,025 people without any disease) were included in the analysis. As a result of the median regression analysis, stroke had the strongest impact on the HRQoL for both males and females, followed by osteoporosis, osteoarthritis, rheumatic arthritis, and herniation of an intervertebral disc. While asthma had a significant impact on the HRQoL only in men, cataract, temporo-mandibular dysfunction, and peptic ulcer significantly affected the HRQoL only in women. CONCLUSIONS: Stroke and musculoskeletal diseases were associated with the largest losses of the HRQoL in Korean adults.

Although cytomegalovirus (CMV) infection of the gastrointestinal tract can occur in persons with normal immune function, it almost exclusively affects the immunocompromised host such as transplant recipients and AIDS patients, and it can cause significant clinical illness. CMV remains the single most important pathogen that affects solid organ transplant recipients. While CMV can affect any segment of the gastrointestinal tract, the colon is the most common site of infection, and this is followed by the upper gastrointestinal tract. However, CMV infection associated with simultaneous gastric and colonic ulcer is very rare and this has been reported in only one case, and a case of simultaneous gastric, duodenal and colonic ulcer associated with CMV infection has not yet been reported in Korea. We report here on a case of simultaneous gastric, duodenal and colonic ulcer associated with CMV infection that showed the characteristic histologic findings seen for CMV infection in renal transplant recipients.
