Allelic deletions involving the short arm of chromosome 3(3p13-21.1) have been observed frequently in cervical carcinomas. Recently the fragile histidine triad(FHIT) gene was cloned and mapped to this chromosomal region(3p14.2). From various studies involving tumor cell lines and primary cancers, the FHIT gene has been presumed to be a candidate for tumor suppressor gene involving various tumors. In FHIT gene, the most common aphidicolin-inducible fragile site, FRA3B exists and the FRA3B has been considered as a region of the spontaneous integration site of HPV 16. In order to elucidate the role of the FHIT in carcinogenesis of cervical cancer, this study was designed to investigate both the expression of FHIT protein in normal, preinvasive and invasive cancer samples employing immunohistochemical study and allelic loss of FHIT gene locus against several microsatellite markers employing the PCR analysis. Immunohistochemical studies of FHIT protein revealed following features. In normal ectocervical squamous epithelium, the expression of FHIT was relatively weak and confined to the basal layer, but in normal endocervical glandular epithelium it was very strong. The expression of FHIT was reduced as the tumor progressed from early lesion to invasive cancer. The koilocytosis was associated with diminished expression of FHIT protein. The study of allelic loss of FHIT gene locus was undertaken against two intragenic (D3S1300, D3S1234) and one extragenic (D3S1295) microsatellite markers. The 5th intron, D3S1300, showed allelic change in 6 of 15 assays and 7th intron, D3S1234 showed allelic change in 10 of 29 assays. There was no apparent LOH from 29 assays in D3S1295. In conclusion, the expression of FHIT protein was markedly reduced or absent in cervical squamous cell carcinoma and the chromosome breakage in FHIT region might be related to the diminished expression of FHIT. On the basis of the reduced expression of FHIT and its encompassment of FRA3B region, it is suggested that disruption of FHIT, a putative tumor suppressor gene, might be the mechanism by which HPV infection enhances cervical tumorigenesis and clonal outgrowth.

Giant cell arteritis is a focal granulomatous inflammation of arteries of medium and small size that affects principally the cranial vessels, especially the temporal arteries, in older individuals. It appears to be a localized process; its significance apparantly depends on the organ affected. A 67-year-old man was admitted to hospital because of the left scrotal mass and pain lasting for 1 month. On physical examination, the hard masses were palpated at the superior part of the left epididymis without tenderness. Histologically, the spermatic cord showed granulomatous arteritis involving the small and medium sized arteries with a transmural inflammatory infiltrates centered on the inner media, and composed of lymphocytes, histiocytes, some eosinophils and multinucleated giant cells. The elastic tissue stain revealed the fragmentation of the internal elastic lamina along with numerous epithelioid histiocytes and giant cells.

Although there have been many reports about the importance of the spleen's role in hepatic fibrogenesis, the exact mechanism is still uncertain. The author designed this study to evaluate splenic function on hepatic fibrogenesis. The degree of hepatic fibrosis and the population of splenocyte subsets were studied in the experimental animal model with fibrosis produced by injecting normal swine serum intra-peritoneally into Sprague-Dawley rats. The animals were divided into three groups; group A was subjected to injection of swine serum only, group B swine serum and complete Freund's adjuvant and group C swine serum and cyclosporin A. The experimental hepatic fibrogenesis by swine serum was augumented by coinjection with the adjuvant and inhibited by cyclosporin A. The study of the splenocyte subset revealed increased percentages of spienic B cell and CD4+ cell and a decreased percentage of CD8+ cell, and these changes of splenocyte subset were also augumented by the adjuvant and inhibited by cyclosporin A. The percent of monocytes was not significantly altered, although a tendancy of early decrease by the adjuvant was noted.

PURPOSE: This study aims to investigate the relationships between knowledge on advance directive, attitudes towards the withdrawal of life-sustaining treatment and quality of life among hemodialysis patients. METHODS: A descriptive correlational study was conducted with 103 hemodialysis patients. Data were collected using a structured questionnaire from May to September of 2016, and analysed by using descriptive statistics, t-test, ANOVA and Pearson correlation coefficient. RESULTS: The participants' knowledge level on advance directive was 5.47±2.08 out of 9, the attitudes towards the withdrawal of life-sustaining treatment was 3.22±0.49 out of 5, and the quality of life was 3.35±0.92 out of 6. The knowledge on advance directive was positively correlated with attitudes towards the withdrawal of life-sustaining treatment (r=.21, p=.037) and quality of life (r=.21, p=.036). CONCLUSION: According to the results of this study, the level of knowledge on advance directive is preferred to improve the quality of life of hemodialysis patients. It is needed to support and maintain ongoing education opportunities in order to improve the level of knowledge on advance directive among patients undergoing hemodialysis.

PURPOSE: The aim of this study was to investigate the relationships between the hemodialysis unit nurses' experience of verbal abuse, job stress, burnout, and turnover intention, and to identify the explained variances for turnover intention. METHODS: The research design was a descriptive survey using a probability sampling. The data were measured using self-report questionnaires from 231 hemodialysis unit nurses in seven cities in Korea and were analyzed with SPSS 20.0. RESULTS: The mean scores were 2.45±0.62 (out of 5) for experience of verbal abuse, 2.40±0.26 (out of 4) for job stress, 2.31±0.48 (out of 4) for burnout, and 3.16±0.05 (out of 5) for turnover intention. There were significant correlations among the experience of verbal abuse, job stress, burnout, and turnover intention within the hemodialysis unit nurses. Factors influencing turnover intention were 'burnout' (β=.42, p<.001) and 'job stress' (β=.17, p=.015)which explained 42% of the variance (F=15.98, p<.001). CONCLUSION: Results suggest that in order to reduce nurses' turnover intention, nurse managers should explore strategies to reduce nurses' burnout and job stress in nurses in hemodialysis units.

The term "pineal anlage tumor" has been recently proposed and few cases have been reported. We report the first Korean case of pineal anlage tumor in a 6-year-old girl who complained of headache and vomiting for 2 months. Brain MRI revealed a well defined, lobulated, calcifying mass in the pineal region. Tumor was totally removed. Pathological examination revealed a primitive pineal parenchymal tumor with melanotic epithelial component that was similar to histologic findings of melanotic neuroectodermal tumor of infancy, so-called retinal anlage tumor and of the developing pineal gland. The tumor was composed mostly of small, undifferentiated cells, Flexner-Wintersteiner rosettes, and ganglionic differentiation. The tumor also contained the cartilage and skeletal muscle cells.

PURPOSE: The purpose of this study was to evaluate the factors which are related to the maternal role performance of first-time mother to improve the health of infant. Specifically a basic hypothetical model was developed based on the previous study about a model of social networks. METHOD: The survey was done from January to February in 2001. Total 257 mothers who have four to twelve month old first-time baby was interviewed in five community health center around country(Seoul, Choung-ju, Asan, Cheon-an, Jeju). Finally 247 data was analyzed. Data analysis was done with LISREL 8.20 program for covariance structural analysis. RESULTS: Compared to the hypothetical model, the revised model has become parsimonious and had a better fit to the data(X(2)=167.55(p=.00), X(2)/df=1.48, GFI=0.97, AGFI=0.95, RMR=0.049, NFI=0.98, NNFI=0.99, CN= 222.53). All predictive variables of the maternal role of first-time mother explained 30% of total variance in model. Social network structural characteristics and social network interactional characteristics had significant effect on the emotional support and the information support. And social network interactional characteristics had significant effect on the service support, material support and social companionship support. The service support and social companionship support had significant effect on the maternal role strain. The emotional support and the social companionship support had significant effect on the maternal role of first-time mother. CONCLUSION: As the conclusion of this study, there is in need of the developing the programmes focussed on the social network for the first-time mother.
