Epidemiological evidence suggests that human papillomavirus(HPV) infection is a high risk factor for the development of oral cancers. Many oncogenes, especially p53 suppressor gene, have a critical role of carcinogenesis in several human cancers including oral cancers. To investigate the prevalence of HPV infection and subtyping of high risk group(HPV-16, -18 and -33) HPV in oral cancers, the author studied 31 cases of squamous cell carcinomas arising from the oral cavity using polymerase chain reaction (PCR). The author also demonstrated the overexpression of p53 oncoprotein in the oral cancers using immunohistochemical methods. The correlation between HPVs infection and p53 overexpression in tumorigenesis of the oral cancers was evaluated. 1. Twenty-one cases(66.7%) among 31 cases of oral squamous cell carcinomas were positive for HPV-DNA. Among them, 16 cases were positive for HPV-16, 4 cases for HPV-18, and 2 cases for HPV-33. Two cases were coinfected with HPV-16 and HPV-18, and HPV-18 and HPV-33. 2. The prevalence of HPV infection appeared not correlated with tumor differentiation and clinical stages of oral squamous cell carcinomas. 3. The overexpression of p53 oncoprotein was present in 24 of 31 cases(77% ). In 21 HPV positive tumors 18 cases were positive for overexpression of p53 oncoprotein. Six cases were positive for p53 in ten HPV negative tumors. There was no correlation between HPV DNA detection rate and p53 overexpression. The above results suggest that HPV infection and p53 oncogene mutation play different roles in tumorigenesis of oral squamous cell carcinomas. No coexpression of p53 oncoprotein with HPV-DNA detection suggests that another etiologic mechanism other than HPV infection may be operative.

A study was made of the differences in clinical features and immunological aspects between herpes zoster patients with malignancies and those without malignant tumors. The results obtained from the retrospective review of medical records are as follows: Herpes zoster occurred more frequently in younger patients(less than twenty) with malignanciee as compared with the control group of the same ages,' Male was dominant among zoster patients with malignancies as is the contrary to contral group; Tihere were no marked differences in primarilly involved dermatomes between the two groups; Generalized varicelliform eruptiona were more common in zoster pa,tients with malignaneies than in control group, It seemed that zoster patients with malignancies complained of milder degree of pain. Zoeter patienta associated with malignancies were more frequently DNCB-negative and had decreased OKT3+ pan T cells, OKT4+ helper/inducer T cells as compared with control group, which suggest impaired cell mediated immunity in the former.

Background & PURPOSE:Since the 1970's the rate of breast-feeding has decreased significantly. The Korean National Institute of Health reported that the rate of breastfeeding was 68.9% in 1982 and 14.1% in 1997. There are many influencing factors including: the lack of education and information on breast feeding, lack of faith in breast feeding, increment of the rate of working, lack of encouragement by supporters in difficult situations, and nurses' low level of knowledge about breast feeding. Such a lack of knowledge and support of breast-feeding at home by family members create another dilemma to the problem of breast-feeding. If problems arise and family members are unable to provide assistance due to the deficiency of knowledge, mothers show a tendency to abandon breast-feeding. The purpose of this research is to find out the rate of breast-feeding practice by time sequence of 1 week, 6 weeks and 12 weeks after birth and influencing factors on breast-feeding practice centered on the postpartal women who were 3discharged from one hospital, which is located in Seoul and provides simple breast-feeding education and continuous postnatal telephone consultation. Methodology: The subjects of this research were 54 women who gave birth in a hospital located in Seoul from 1 March 2000 to 31 April 2000. After birth the subjects were educated individually about breast-feeding and telephone consultations were conducted. On the 1st week, 6th week, and 12th week, the subjects were surveyed about their breast-feeding practice rates and methods by telephone. Results: 1) Complete breast-feeding rate: Within one week after birth, the subjects showed 64.2% complete breast-feeding rate. Within 6 weeks, 39.6%, and 12 weeks, 34.1%. 2)Partial breast-feeding rate: Within one week after birth, the subjects showed 32.1% partial breast-feeding rate. Within 6 weeks, 39.6%, and 12 weeks 15.1%. 3)Complete bottle-feeding rate Within one week after birth, the subjects showed 1.9% complete bottle-feeding rate. Within 6 weeks of giving birth 15.1%, and 12 weeks 17.0%. These results show that individual education about breast-feeding and continuous postnatal telephone consultation influenced on the practice of breast-feeding. On considering the reality of the hospital situation in which nurses could not operate education program due to the work-load, it is necessary to find out selectively those mothers who are unable to breast feed and provide education individually and continuous support by telephone follow up. Futhermore, the active role of lactation nurse specialist and their efficient management of breast-feeding for the successful practice is required.

PURPOSE: The F9 gene is known to be the causative gene for hemophilia B, but unfortunately the detection rate for restriction fragment length polymorphism-based linkage analysis is only 55.6%. Direct DNA sequencing can detect 98% of mutations, but this alternative procedure is very costly. Here, we conducted multiplex polymerase chain reactions (PCRs) and conformation sensitive gel electrophoresis (CSGE) to perform a screened DNA sequencing for the F9 gene, and we compared the results with direct sequencing in terms of accuracy, cost, simplicity, and time consumption. METHODS: A total of 27 unrelated hemophilia B patients were enrolled. Direct DNA sequencing was performed for 27 patients by a separate institute, and multiplex PCR-CSGE screened sequencing was done in our laboratory. Results of the direct DNA sequencing were used as a reference, to which the results of the multiplex PCR-CSGE screened sequencing were compared. For the patients whose mutation was not detected by the 2 methods, multiplex ligation-dependent probe amplification (MLPA) was conducted. RESULTS: With direct sequencing, the mutations could be identified from 26 patients (96.3%), whereas for multiplex PCR-CSGE screened sequencing, the mutations could be detected in 23 (85.2%). One patient's mutation was identified by MLPA. A total of 21 different mutations were found among the 27 patients. CONCLUSION: Multiplex PCR-CSGE screened DNA sequencing detected 88.9% of mutations and reduced costs by 55.7% compared with direct DNA sequencing. However, it was more labor-intensive and time-consuming.

BACKGROUND:Acute seizures that increase neuronal activity cause a rapid and transient induction of the immmediate early c-fos in specific brain regions. C-fos gene may mediate long-term changes in cell function, such as growth, differeniation, and development, in response to acute extracellular stimulation. This study is designed to compare the expression of Fos protein in hippocampus after single and repeated injections of kainic acid (KA). METHODS:In KA-single injection model, twelve adult male Sprague-Dawley rats were treated with single intraperitoneal injection of convulsive dose(20-30 mg/kg) of KA, and. in KA-multiple injections model, seven rats received KA by repeated daily intraperitoneal injections for 15 days. Eight control rats received normal saline. Expression of Fos protein was tested in hippocampus by immunohistochemical staining, and was scored by the degree of staining intensity and the ratio of stained cells to tested ones. RESULTS:The scores tended to increase in CA3 and dentate gyrus were significantly higher in KA-single injection model than in control (p<0.05). In comparison with scores in KA-model. CONCLUSION:These results show that repeated seizure produces some blockade of c-fos induction in CA2, CA3 and dentate gyrus. This may be a long-term adaptive response by the nervous system to repated neuronal activation

PURPOSE: The purpose of this study was to identify the factors influencing quality of life of married immigrant women in Korea. METHODS: The participants included 508 married immigrant women who met the eligibility criteria and agreed to participate in the study. Participants were evaluated for subjective assessment of married immigrant-related constructs using a self-report questionnaire, for self-esteem, self-efficacy, and quality of life (QOL). The analysis was done using SPSS for Windows, version 10.1, and included stepwise regression. RESULTS: The major findings were as follows; 1) There were significant relationships between marital satisfaction (r=.39, p=.001), violence by the husband during the couple's arguments (r= -.24, p<.001), satisfaction with life in Korea (r=.39, p<.001), self-esteem (r=.16, p<.001), self-efficacy (r=.51, p<.001) and quality of life. 2) Marital satisfaction, self-efficacy, education level and satisfaction life with in Korea were significant factors, which explained 53% of the variance in quality of life (F=43.97, p<.001). Multiple regression analysis revealed that a powerful predictor of QOL for married immigrant women was self-efficacy. CONCLUSION: Developing nursing interventions to enhance self-efficacy toward improvement of QOL among married immigrant women is recommended.

PURPOSE: The purpose of this study was to discover kidney transplant and hemodialysis patients' quality of life(QOL) and provide basic data to improve their QOL. METHOD: One hundred two hemodialysis patients and 106 kidney transplant patients were given a self-administered questionnaire from Mar. 6 to Mar. 31, 2006. The instrument consisted of demographic variables, therapeutic-related characteristics and QOL. Collected data was processed using the SPSS 12.0 statistical program for real numbers, percentages, ANCOVA, t-test, ANOVA, Stepwise multiple regression and the Scheffe test. RESULTS: Kidney transplantpatients' QOL was higher than hemodialysis patients. The demographic variables which showed a significant difference in overall QOL were religion, children and monthly income for kidney transplantpatients and educational background for hemodialysis patients. The therapeutic-related variable which showed a significant difference in overall QOL was the patients' perceived health condition for both groups. The influencing factor on overall QOL for both groups was the health condition perceived by themselves. The total variance of the variable for QOL was 42% for kidney transplant patients and 19% for hemodialysis patients. CONCLUSION: This study revealed that kidney transplant patients have a higher QOL and how patients perceive their health is the strongest influencing factor for QOL. However, there is a large difference between the demand and supply of kidney donors. To solve this problem the standards for donation should be reviewed and revised.
