Normal C3WHeN strain mice exposed to topical 8inethoxypsomlen plus long wave ultraviolet (PUVA) showed a reduction in contact hypersensitivity, (CH) which was localized to the skin in the area of PUVA treatment (local suppression), whereas systemic PUVA treatment caused diffuse suppression of CH reaction, regardless of the application site of 2,4-dinitro-1-fluorobenzene (DNFB). There seem to be two different mechanisms responsible for CH reduction by PUVA. Local suppression by topical PUVA treatment was thought to be a result of blocking the afferent phase of immune response, it was associated with a lack of CH effector cells in the peripheral lymph nodes and could not be reversed by indomethacin treatment. Diffuse suppression induced by systemic PUVA treatment seemed to be associated with blocking of egress of effector cells from the regional lymph nodes, this depressed CH response was prevented when indomethacin was administered before PUVA treatment.

BACKGROUND/AIMS: There is considerable variance in individual susceptibility to hepato-toxic effects of ethanol as evidenced by the finding that only about 10-20% of alcoholics develop alcoholic liver cirrhosis. The aims of this study were, 1) to get the data on the genetic polymorphisms of three major ethanol-metabolizing enzymes (ADH, CYP2E1, ALDH) in normal Korean adults, and to search for the specific genotypes influencing alcohol drinking behavior by the comparison of allele frequencies between healthy control group and heavy drinker group with or without liver disease, 2) to investigate the influence of the genetic polymorphisms of these enzymes on the susceptibility to alcoholic liver disease by the comparison of allele frequencies between heavy drinker group without liver disease and alcoholic liver cirrhosis group. METHODS: Healthy control group included 53 healthy males in military service without evidence of liver disease or alcoholism. Heavy drinker group without liver cirrhosis included 29 males who had been drinking 80g or more of alcohol daily for more than ten years but did not have any clinical evidence of liver disease. Alcoholic cirrhosis group included 43 male patients who had drunk 80g or more of alcohol daily for more than ten years and had clinical evidences of overt cirrhosis. Subjects with hepatitis B surface antigen or anti-hepatitis C antibody were excluded. Genotypes of the three enzymes were determined by PCR (polymerase chain reaction) and restriction fragment length polymorphism (RFLP) with genomic DNAs extracted from peripheral leukocytes. RESULTS: 1) In healthy Korean males, allele frequency of ADH22, ADH31, CYP2E1 c2 and ALDH22 was 81%, 94%, 30% and 14%, respectively. 2) The absence of ALDH22 or CYP2E1 c2 allele were significant risk factors for being a heavy drinker (odds ratio,' 0.09, 0.42, respectively). 3) Although it was not associated with the polymorphism of each ethanol-metabolizing enzymes, the susceptibility to alcoholic liver cirrhosis was significantly associated with combined genotypes of ADH2(22) & ADH3(1+1)& CYP2E1 B or C. COMCLUSION: Genetic polymorphisms of ethanol-metabolizing enzyrnes are significantly associated with the suseptability to alcoholic liver disease as well as alcohol drinking behavior.

PURPOSE: This study was to investigate the current situation of community health nursing practicum in bachelor programs. METHOD: Data were collected using a questionnaire consisting of questions on education goals, teaching items, teaching methods, and evaluation methods and items. Forty five nursing departments/colleges or 84.9% of four-year nursing schools in Korea responded to the survey. RESULT: Nursing process application and understanding about the role and function of community health nurses were major goals of practice education. Community health centers were the most significant practice fields because all nursing schools mentioned them as places for practice. All nursing schools used a specific evaluation tool to measure students outcomes and utilized guidebooks to help students. CONCLUSION: The results of this study suggest that the goals of practice education should be standardized to improve the quality of education. Besides, evaluation tools that can be used commonly at all nursing schools should be developed to measure the effectiveness of practice education of community health nursing.

The purpose of this study was to determine the effect of finish line design, amount of incisal reduction, and loading condition on the stress distribution in anterior all-ceramic crowns. Three-dimensional finite element models of an incisor all-ceramic crown with 3 different finish line designs : 1) shoulder with sharp line angle 2) shoulder with rounder line angle 3) chamfer : and 2 different incisal reductions : 2mm and 4mm were developed. 300 N force with the direction of 45 degree to the long axis of the tooth was applied at 3 different positions : A) incisal 1/3, B) incisal edge, C) cervical 1/5. Stresses developed in ceramic and cement were analyzed using three-dimensional finite element method. The results were as follows : 1. Stresses were concentrated in the margin region, which were primarily compressive in the labil and tensile in the lingual. 2. Stresses were larger in the area near line angle than on the crown surface of the margin region. In case of shoulder with sharp line angle, stresses were highly concentrated in the porcelain near line angle. 3. At the interface between porcelain and cement and at the porcelain above the margin on crown surface, stresses were the highest in chamfer, and decreased in shoulder with sharp line angle and shoulder with rounded line angle, respectively. 4. At the interface between cement and abutment on crown surface, stresses were the highest in shoulder with sharp line angle, and decreased in shoulder with rounded line angle and chamfer, respectively. 5. The amount of incisal reduction had little influence on the stress distribution in all-ceramic crowns. 6. When load was applied at the incisal edge, higher stresses were developed in the margin region and the incisal edge than under the other loading conditions. 7. When load was applied at the cervical 1/5, stresses were very low as a whole.

Adenocarcinoma of small intestine is rare disease, but its incidence of iluem is the least of small intestinal adenocarcinoma. Its rarity and vague symptoms results in delayed diagnosis, treatment and poor prognosis, Recently we experienced a 65 years old man of ileal adenocarcinoma with liver metastasis, which does not obstuct intestinal lumen, We treat the metastatic tumor with chemoembolization(lipiodol and doxorubicin) through the hepatic artery and so we report the case with review of literature.

OBJECTIVES: Echocardiographically determined left ventricular hypertrophy is associated with increased risk for sudden cardiae death and for complex ventricular arrhythmias in 24-hour ambulatory electrocardiographic monitoring. In subjects with left ventricular hypertrophy, the presence of asymptomatic complex ventricular arrhythmias is associated with higher incidence of sudden cardiac death and higher cardiovascular mortality. However, their accurate relationship and prognostic significances have been remained to be established. The purpose of this study was to evaluate the relationship between complex ventricular arrhythmias, left ventricular hypertrophy, and sudden cardiac death in Korean patients. METHODS: Twenty four hour ambulatory electrocardiographic monitoring, echocardiographic data and medical records were reviewed in 360 subjects from 1991 to 1994. We evaluated the relationship between complex ventricular arrhythmias and left ventricular mass index, and the prognostic values of them. Of the 360 subjects, 187 could be followed up for one to four years. The mean follow-up period was 2.8 years. RESULTS: The incidence of complex ventricular arrhythmias was significantly correlated with left ventricular mass index and ejection fraction in all subjects. During the follow-up periods, seven of 187 subjects died from sudden cardiac death. Six of them had complex ventricular arrhythmias with left ventricular hypertrophy. CONCLUSION: The incidence of complex ventricular arrhythmias was significantly correlated with echocardiographically determined left ventricular hypertrophy and it is suggested that subjects with complex ventricular arrhythmias combined with left ventricular hypertrophy have higher risk for sudden cardiac death.

Four hundred and sixty five randomly selected clones from a cDNA library of Blattella germanica were partially sequenced and searched using BLAST as a means of analyzing the transcribed sequences of its genome. A total of 363 expressed sequence tags (ESTs) were generated from 465 clones after editing and trimming the vector and ambiguous sequences. About 42% (154/363) of these clones showed significant homology with other data base registered genes. These new B. germanica genes constituted a broad range of transcripts distributed among ribosomal proteins, energy metabolism, allergens, proteases, protease inhibitors, enzymes, translation, cell signaling pathways, and proteins of unknown function. Eighty clones were not well-matched by database searches, and these represent new B. germanica-specific ESTs. Some genes which drew our attention are discussed. The information obtained increases our understanding of the B. germanica genome.

PURPOSE: The purpose of this study was to analyze the research papers published in three nursing journals to suggest the direction for Journal of Korean Oncology Nursing (JKON). METHODS: To compare JKON with Journal of Korean Academic Society of Nursing Education and Cancer Nursing, all the research papers published in those three journals, 2010 were reviewed using an analysis criteria developed by the researchers, focusing on type of research, characteristics of authors and subjects, research design, data collection and analysis methods, sample size estimation, and ethical considerations regarding data collection. RESULTS: JKON lacked research papers which were supported by research funds, produced by multidisciplinary teams, addressing cancer survivors or patients with metastatic cancers, and written in qualitative methodologies. However, JKON showed higher ratio of research papers than the other two journals which were adapted from thesis or dissertations, describing sample size estimation process precisely, and participating subjects diagnosed with various cancers. CONCLUSION: The study found out that JKON is presenting well the area of oncology nursing in Korea and also has several weak points that need to be improved. The study therefore suggested several recommendations for the JKON to take the professional and global leader roles.
