Ochratoxin A is a natural contaminant of mouldy food and feed, which is produced by Penicillium and Aspergillus, and is suspected of being one of the etiological agents responsible for Balkan endemic nephropathy and the associated urinary tract tumors. For evaluation of the mutagenicity of ochratoxin A, we performed in vitro chromosome aberration tests using Chinese hamster lung fibroblast cells (CHL cells) and monkey kidney cells (VERO cells), in vivo micronueleus tests using ddY mouse bone marrow cells and somatic mutation and recombination tests (SMART) using Drosophila melanogaster. The results of chromosome aberration tests in CHL cells showed no incidence of increased structural and numerical aberrations regardless of metabolic activation, while in VERO cells treated with 2.0, 1.0, 0.5, 0.3 ug/ml of ochratoxin A showed significant increase of structural aberrations without metabolic activation. Aspartame and-phenylalanine, structural analogs of ochratoxin A, didn't affect the chromosome aberrations induced by ochratoxin A. The in vivo induction of micronucleated polychromatic erythrocytes were measured in bone marrows of ddY mice treated with 10.0, 5.0, 2.5mg/kg/10ml of ochratoxin A through intraperitoneal route once. At 24 and 48 hours after treatment, ochratoxin A didn't induce micronuclei in bone marrows of ddY mice. And at the concentration of 40, 20, 10 ug/ml of ochratoxin A, which was administered by feeding to larvae of Drosophila melanogaster, showed no incidence of increased multiple wing hairs and flares. Summarizing all results, we concluded that ochratoxin A is a kidney cell specific direct genotoxicant.

PURPOSE: The purpose of this study was to identify the trends in research studies published in Journal of Korean Academy of Fundamentals of Nursing from 2009 to 2011. METHODS: A total of 156 studies published between 2009 and 2011 were reviewed using analysis criteria developed by the researchers. RESULTS: Quantitative studies accounted for 90.4% and qualitative studies, 8.3%. The research designs for the quantitative studies were experimental, 28.0% and survey, 63.8%. IRB approval was received for only 25.6% of the studies and 61.0% of studies presented participant criteria. Questionnaires were used for data collection in 90.8% of studies. Individual or group education was the most frequent intervention in the experimental studies. CONCLUSION: The results indicate that more randomized controlled trials with a low risk of bias are needed to support greater evidence-based nursing practice. Considering the low rate of ethical consideration, it is important that stricter application of research methods needs to be encouraged to improve the quality of Journal of Korean Academy of Fundamentals of Nursing.

PURPOSE: The purpose of this study was to identify content of Fundamental Nursing Practice (FNP) and the educational needs for nursing practice items in schools of nursing. METHODS: Participants were 81 professors who were teaching FNP and 166 clinical nurses. The research questionnaire included 148 practice items, which were selected by content analysis of 7 FNP textbooks. Data were collected from May 20 to July 27, 2011 and analyzed using descriptive statistics and t-test with SPSS 17.0. RESULTS: The research findings showed that : 1) the seven items included in the education content of all schools of nursing were putting on sterile gloves, checking radial pulse, checking blood pressure in the arm, Foley catheterization, injection preparation with ampule, intramuscular injection in the buttocks, and mixing intravenous fluid. Fifty items were included in the content in more than 80% of the schools. 2) Educational domains needing emphasis were medication, infection control, health assessment, oxygenation, urinary elimination, activity/positioning, and nutrition. There were significant differences in reported educational needs between professors and clinical nurses for 62.8% of practice items. CONCLUSIONS: Results indicated that standardization of FNP education contents using the findings of this study should lead to improvement in quality of FNP education.

The purpose of this research was to uncover the expertise of ICU nursing in Korea, and to describe nurses' practice based on the degree of skill acquisition. A total of 18 ICU nurses participated in the study. The data was collected through individual in-depth interviews and it was managed using the NUDIST 4.0 software program. The data was analyzed using interpretive phenomenology suggested by Benner. Four properties of expertise of ICU nursing were identified. These are 1) concern and love toward patients; 2) knowledge; 3) skill, and 4) abilities in interpersonal relationships. And the characterisitcs of four levels of skill acquisition, that is advanced beginner, competent, proficient, and expert, were described with exemplars. The results of this study might help nurse researchers clarify and elaborate on the concept of expertise in ICU nursing, and enable them to understand how the process of skill acquisition occurs in the ICU setting. They might also help nurse managers establish educational goals for ICU nursing for student or novice nurses.
