In order to find out a valuable control measure for soil-transmitted parasties, the infectivity in mice of Ascaris eggs irradiated with Cobalt(60) were examined. The results were summarised as follows. In vitro, Ascaris eggs irradiated with larger doses of Cobalt(60) developed poorly, and no difference was found between fresh eggs and those cultured for a few days. Ascaris eggs irradiated with doses of 200,000 rad. developed at the rate of 90 percent after 4 weeks, whereas those irradiated with 1,000,000 rad. developed 28 percent. Ascaris eggs irradiated with Cobalt(60) after 2 weeks of culture were poor in development compared with those of 4 week culture. Eggs cultured for 5 weeks showed weaker infectivity in mice than those cultured for 8 weeks. In the control groups, the infectivity in mice of Ascaris eggs was remained the same between 5 and 8 weeks. The minimum dose of Cobalt(60) irradiation effective for preventing infectivity in mice was estimated to be 200,000 rad.

PURPOSE: PVP using a high-power potassium-titanly-phosphate(KTP) laser offers safe and efficacious surgical therapy for men with symptomatic BPH. To demonstrate its efficacy, safety and durability, we present the results of PVP for treatment of BPH with 12 month follow-up. MATERIALS AND METHODS: 104 consecutive men with symptomatic BPH underwent PVP with an 80 W KTP laser (Laserscope) between July 2003 and August 2004. All underwent preoperative and postoperative evaluation, including assessments of international prostate symptom score(IPSS), quality of life(QOL), peak urinary flow rate(Qmax), post-void residual volume(PVR), prostate specific antigen(PSA), and ultrasound prostate volume(PV). Secondary outcome parameters included surgical time, anesthesia, and length of catheterization. Follow-up assessment occurred at 1, 3, 6, and 12 months. Data were analyzed using the Wilcoxon signed rank test. RESULTS: Preoperative mean PV was 57.2+/-4.2 ml. PV decreased to 38.9, 35.4, 32.8 and 35.8 at 1, 3, 6 and 12 months (p <0.01 versus preoperative value). Mean improvements in IPSS, QOL, Qmax, and PVR at 12 months were 67%, 81%, 138% and 94%, respectively(p <0.001). Mean operative time was 26.3+/-15.0 minutes. Anesthesia included pudendal and prostatic block(n=102) and spinal anesthesia(n=2). Ninety-nine(95%) patients were treated as outpatients( <12 hrs) and the remaining 5 patients were admitted for 1 or 2 hospital days. Mean catheterization times were 9.8+/-3.1 hours(range 0~72), with 28(27%) patients not requiring a catheter post-operatively. Minor complications included mild hematuria lasting 3 weeks(3.8%), transient post-operative retention(2.9%), urge incontinence(1.9%), transient dysuria(25%), frequency(21.2%), urgency(17.3%) and retrograde ejaculation(41%). CONCLUSIONS: These results demonstrate that PVP is safe and efficacious for the treatment of symptomatic BPH. Long follow-up will further validate this new modality as the standard for surgical treatment of BPH.

4.Development of a Stress Scale for Elderly Patients with Coronary Artery Disease.
Journal of Korean Academy of Nursing 2014;44(6):630-638
PURPOSE: The purpose of this study was to develop a scale to evaluate stress in elderly patients with coronary artery diseases (CAD) and to examine validity and reliability of the scale. METHODS: The development process for the preliminary scale included construction of a conceptual framework and initial items, verification of content analysis, sentence correction, and pilot study. This study was conducted using a questionnaire survey with one-to-one interviews during January and February, 2012. Participants were 240 elderly patients with CAD. Data were analyzed using item analysis, factor analysis, criterion related validity, and internal consistency. RESULTS: The developed scale consisted of 32 items and 6 factors - aging and disease (7 items), family relations (5 items), anxiety and withdrawal (9 items), management of daily living (3 items), compliance of medical regimen (4 items), poverty and finance (4 items), and explained 68.5% of total variance. The scale had significantly positive correlation with the Korean Perceived Stress Scale (KPSS). Cronbach's alpha was .96, and Guttman split half coefficient was .91. CONCLUSION: Results indicate that the Stress Scale for Elderly Patients with CAD has validity and reliability, and is a suitable scale in health care settings to assess stress in elderly patients with CAD.

PURPOSE: This Study was conducted to estimate the prevalence rate, and related factors,of fatty liver in male industrial workers. METHOD: Fatty liver was diagnosed using ultrasonography. The data for abdominal ultrasonography, BMI, smoking, alcohol drinking, exercise, liver enzymes, and lipid profiles were collected in 4,604 male who were examined with a health screening program in 2005. Prevalence rate and associated factors of fatty liver were analyzed using SPSS v. 12.0. RESULTS: Overall prevalence of fatty liver was 34.1% and higher in the 30-39 year male group. Age, body mass index(BMI), hypertriglyceridemia, hypercholesterolemia, HDL cholesterol, r-GTP level were independently associated factors with presence of fatty liver in logistic regression analysis. CONCLUSION: The prevalence of fatty liver and tendency of associated factors were similar to those in the western world. To prevent development of this hepatic disorder, which may result in end-stage liver disease, risk factors such as obesity and dyslipidemia must be monitored and controlled within normal levels. The results of this study suggested maintenance of a healthy lifestyle, including diet, exercise, and behavioral change, as fundamental rehabilitation nursing implications.

PURPOSE: The purpose of this study was to describe quality of life (QOL) in Korean school-age children by identifying dimensions and attributes of QOL from the child's point of view. METHOD: In-depth interviews with focus questions were used for the study. Twelve children, aged 10 to 13 years, were recruited from Seoul and rural areas. The interviews were audio-taped and transcribed before content analysis. The data were analyzed for themes and attributes. The researchers read the data together and discussed their conclusions until a consensus was reached. RESULTS: Eight dimensions, 57 subdimensions and 101atttributes were identified for QOL in school-age children. The eight dimensions of QOL were physical, social, emotional, learning, leisure, family, self-value, and material aspects. CONCLUSION: The study results can be utilized in developing reliable instruments to measure quality of life specific to school-age children. It is proposed that a consistent and unified policy should be established by school, family, and community for the purpose of improving the QOL of school-age children.

BACKGROUND: Tandem duplication of chromosome 17p11.2-p12 including peripheral myelin protein 22 (PMP22) gene is the most frequent cause of Charcot-Marie-Tooth 1A (CMT1A). Patients carrying one extra copy of PMP22 develop CMT1A, whereas the deletion of the 17p11.2-p12 region causes hereditary neuropathy with the liability to pressure palsies (HNPP). In the present study, we established the genotyping methods of 6 microsatellite markers (D17S921, D17S9B, D17S9A, D17S4A, D17S918 and D17S122) within the 17p11.2-p12 regions by the hexaplex PCR for the genetic diagnosis of CMT1A duplication and HNPP deletion. METHODS: We established polymorphic behavior and genotyping methods of 6 microsatellite markers (D17S921, D17S9B, D17S9A, D17S4A, D17S918 and D17S122) within the duplication region. The 6 markers were amplified by hexaplex PCR reaction and analyzed by an automatic sequencing analyzer and genotyper program. RESULTS: The genotype distributions of all markers were not significantly deviated from the Hardy-Weinberg equilibrium (P>or=0.05). When comparing the control group and CMT1A, HNPP patients group by the distribution of allele, there is no significant difference in the 5 locus except in the 1 locus (D17S921) among HNPP patients. The specificity was more than 99.9%. The sensitivity of each CMT1 and HNPP was 56.3% (40/71 pedigrees) and 72.1% (31/43 HNPP pedigrees), respectively. CONCLUSIONS: The error rate for the system may be less than 0.001. According to this study, it is possible to have rapid and exact genetic diagnosis of both CMT1A and HNPP, which may be helpful for the development of personalized therapy according to genetic defects.
