Sixty one cases of gastric adenocarcinoma were studied immunohistochemically for expression of HLA-DR and secretory component(SC) in order to analyze the relationship between expression of these in gastric cancer cells and the adjacent mucosa. Immunostaining was detected within the cytoplasm and on the cell memgrane. The rate of HLA-DR and SC expressions in cancer cells were 59.0% and 49.2%, respectively, and 52.5%/52.5% and 31.2%/50.8% the mucosa in adjacent/remote from the site of to cancer. The SC expression in the adjacent mucosa was lower than that of the remote mucosa(p=0.027). The HLA-DR expression in the cancer cells in the intestinal type of gastric adenocarcinoma(73.9%) was higher than that of the diffuse type(14.3%) and it was statistically significant(p=0.02). The presence of an increased amount of lymphoid infiltration in the gastric mucosa was closely related to the expression of HLA-DR and SC. Decreased or absent expression of SC at the transitional mucosal cells was possibly a result of exposure to genotoxic agents due to the lack of protective function of SC-IgA. From these results, one can postulate that the expression of HLA-DR and SC may play an important role in atleration in microenvironment with lymphoid infiltration.

PURPOSE: This study is to assess the quality of life(QOL) of hematic cancer survivors after hematopoietic stem cell transplantation(HSCT) and received chemotherapy(RC) to prepare basic information for nursing interventions in order to improve the patients' QOL. METHOD: The data were collected by self-reporting questionnaire from January to March, 2003 intended for outpatients at the Cancer center of D university hospital in Busan. All 44 of them were diagnosed as hematic cancer and had spent 100 days after getting HSCT and complete remission(CR) throughout RC. The collected data were analyzed with descriptive statistics, t-test. ANOVA using SPSS/WIN 10.0 program. RESULTS: The total mean score of the QOL was moderate. In case of survivors in HSCT, the total mean score of the QOL was 5.81+/-.08, and that of survivors in RC was 5.94+/-.13. The facts above has not been considered statistically as the result of analysis of differences in each domain of the QOL depending on the general characteristics of the objects of this study. CONCLUSION: The total mean score of the QOL was at moderate levels, indicating that the survivors after HSCT and RC were perceiving their QOL as moderate. In the nursing business aspect, the most important thing is to understand the QOL which the 2 groups of the survivors perceive, and the plans of nursing intervention that can be helpful to more qualitative life should be studied constantly.

The pregnancy causes the marked changes in maternal renal hemodynamic and volume homeostasis. During pregnancy, renal sodium and water retention result in an expansion of extracellular fluid and plamsma volume. This study was to examine the alteration of expression and localization of COX-1, 2, mRNAs and proteins in the kidneys of non-pregnant (NP) and pregnant rats using RT-PCR, Western blot analysis and immunohistochemistry. Pregnant Sprague-Dawley rats were evaluated on various time sets : days 10.5 (P10.5), 12.5 (P12.5), 17.5 (P17.5), and 19.5 (P19.5). In RT-PCR, COX-1 expression was gradually increased from P10.5 to P19.5 compared with NP rat. COX-2 expression was gradually decreased from P10.5 to P17.5 compared with NP rat, but restored NP level at P19.5. In Western blot analysis, COX-1, 2 proteins were detected in ~70, ~72 kDa, respectively. COX-1 expression was gradually increased from P10.5 to P17.5 and peaked at P19.5 compared with NP rat. COX-2 expression of pregnant rats was slightly decreased compared with NP rat. In NP rat, immunoreactivity of COX-1 was detected in entire collecting duct, glomerular epithelium, and medullary interstitial cells. In pregnant rats, the pattern of cellular labeling and signal intensity of COX-1 protein was identical to NP rat, but signal intensity was markedly increased in the inner stripe of outer medulla and inner medulla at P19.5. COX-2 immunoreactivity of NP rat was detected in the cortical thick ascending limb and macula densa. In pregnant rats, the pattern of cellular labeling of COX-2 protein was identical to NP rat, but signal intensity was slightly decreased. These results suggest that the expansion of extracellular fluid volume and water retention may be partly regulated by COX-1 rather than COX-2 during the pregnancy, especially at late stage.

PURPOSE: Cholestatic liver disease is a frequent complication of prolonged parenteral nutrition, especially in premature infants. The purpose of present study is to evaluate the clinical and biochemical efficacy of ursodeoxycholic acid (UDCA) in premature infants with total parenteral nutrition (TPN) cholestasis. METHODS: Retrospective chart review of 31 prematures with TPN cholestasis in Neonatal Intensive Care Unit of Chonnam University Hospital from January 1995 and December 2002 was done. Prematures were divided into two groups based on UDCA treatment: the study group (n=22, with UDCA treatment) and the control group (n=9, without UDCA treatment). Treatment efficacy of UDCA was evaluated by monitoring the changes of serum direct bilirubin level for more than one to two months. RESULTS: In study group, cholestasis appeared at a mean age of 23+/-18.8 days after a mean of 21+/-19.7 days of TPN. UDCA was initiated (ranged 15-30 mg/kg/day) at a mean age of 54+/-22.3 days for a mean of 32+/-19.0 days. There was no significant difference in decrease of direct bilirubin level between the study and control group. However, the day of initial enteral feeding and full enteral feeding were earlier in control group compared with study group. CONCLUSIONS: This study shows that UDCA treatment is not effective in the treatment of TPN cholestasis among premature infants unlike that of results reported in children and adults. To reduce the incidence of TPN cholestasis in premature infants, early introduction of enteral feeding as soon as possible is most important.

BACKGROUND: There is concem about the rising incidence of skin cancer. However, few articles have reported the change in the clinical and epidemiological aspects of skin cancer. OBJECTIVE: We performed this study in order to clarifiy the recent changes in cutaneous premalignant and malignant lesions. METHODS: A statistical analysis was made using 101 cases of cutaneous premalignant lesions and 205 cases of ma]ignant tumors out of a total number of 20,175 new outpatients that visited the Department of Dermatology at the Seoul National University Hospital during a 6 year period(1990-1995). RESULTS: The frequency of premalignant lesions was 0.50% and that of malignant tumors was 1.02%. The frequency showed an increasing tendency compared to previous reports. In the premalignant lesion cases, actinic keratosis was most common and represented a figure of 82.2%. Among the malignant tumors, basal cell carcinoma was most frequent at 24.4%. Age, sex and anatomical site distribution of basal cell carcinoma, malignant melanoma was no different. The mean age of squamous cell carcinoma was greater than in previous reports and main preceding lesions were actinic keratosis and cheilitis. The frequency of lymphoma was markedly increased but the reason for this remains to be determined. CONCLUSION: Our findings showed the continous increasing incidence of skin cancers and emphasize the need for public eduacation, early diagnosis and proper treatment.

6.Research Trends in Quantitative Nursing Studies and Quality Assessment of Intervention Studies in Patients with Heart Failure in South Korea.
Journal of Korean Biological Nursing Science 2017;19(4):227-240
PURPOSE: The purpose of this review was to identify the current status of nursing studies on heart failure (HF) patients in South Korea and to suggest future study direction. METHODS: A literature review of databases such as KoreaMed, KERIS and nursing and allied health journal were searched with key terms ‘heart failure’ and ‘nursing’ for the period from January 2000 to February 2017. A total of 35 studies including 28 articles and 7 theses met the inclusion criteria. RESULTS: Twenty-seven out of 35 studies were observational studies on outpatients and most of the studies did not mention the ejection fraction and New York Heart Association functional classification class (NYHA class) in the inclusion criteria. Self-care and health-related quality of life as psychological factors, and physical activity as a biological factor, were used as main variables. However, we found it difficult to understand how much score indicates better quality of life because of an inconsistent and wide score. In quality assessment, 8 intervention studies had no serious flaws. CONCLUSION: Further studies should consider more biological and social factors influencing HF. The quality assessment with respect to nursing intervention studies in HF showed that randomized and double-blind trials are needed.

7.An Integrative Review of Health-related Quality of Life in Patients with Advanced Heart Failure
Journal of Korean Biological Nursing Science 2019;21(1):22-36
PURPOSE: Even though advanced heart failure (HF) severely affects the patient's health-related quality of life (HRQoL), there is little information regarding this issue. This review is aimed to describe the relevant clinical characteristics of patient with advanced HF and identify factors influencing HRQoL in these patients. METHODS: Empirical articles were searched from electronic databases issued from January 2000 to June 2018 with using the key terms ‘heart failure’ and ‘quality of life’. There were a total of 22 articles that met the inclusion criteria and were analyzed for this study. RESULTS: First, nine studies among 22 studies clearly stated that their participants were samples of patients with advanced HF. Most reviewed studies showed the New York Heart Association (NYHA) class as the criteria for identifying advanced HF. Second, the level of HRQoL varied depending on the measurement tools utilized by the researchers. Third, the NYHA class, gender, and symptoms were mainly associated with HRQoL in patients with advanced HF. Also, nurse- or physician-led intervention, exercise, spiritual-focused intervention, and palliative care improved the HRQoL of the patients with advanced HF. CONCLUSION: This study found that the clear application of criteria for advanced HF and the development of advanced HF-specific HRQoL measurement was needed. Prospective studies should be considered for identifying differences in the levels and factors influencing HRQoL in patients with early stage or advanced HF to design patient-centered care.

Journal of the Korean Society of Biological Psychiatry 2014;21(1):1-13
Normal aging causes changes in the brain volume, connection, function and cognition. The brain changes with increases in age and difference of gender varies at all levels. Studies about normal brain aging using various brain magnetic resonance imaging (MRI) variables such as gray and white matter structural imaging, proton spectroscopy, apparent diffusion coefficient, diffusion tensor imaging and functional MRI are reviewed. Total volume of brain increases after birth but decreases after 9 years old. During adulthood, total volume of brain is relatively stable. After 35 years old, brain shrinks gradually. The changes of gray and white matters by aging show different features. N-acetylaspartate decreases or remains unchanged but choline, creatine and myo-inositol increase with aging. Apparent diffusion coefficient decreases till 20 years old and then becomes stable during adulthood and increase after 60 years old. Diffusion tensor properties in white matter tissue are variable during aging. Resting-state functional connectivity decreases after middle age. Structural and functional brain changes with normal aging are important for studying various psychiatric diseases such as dementia, schizophrenia and bipolar disorder. Our review may be helpful for studying longitudinal changes of these diseases and successful aging.

BACKGROUND: Currently, the incidence of hepatitis A is on the increase in Korea. Although there is emphasis on contact precautions, the nosocomial outbreak of hepatitis A virus (HAV) in healthcare personnel has increased within endemic areas because these workers inevitably come in close contact with patients and work under suboptimal hygiene conditions. In this study, we evaluated the necessity of immunization against HAV for healthcare personnel. METHODS: We investigated the seropositivity of serum immunoglobulin G (IgG) anti-HAV antibody (Ab) in 672 healthcare personnel on the basis of their age-group, sex, and occupation in Soon Chun Hyang University Hospital and Soon Chun Hyang University Bucheon Hospital. RESULTS: The subjects were divided into 6 groups on the basis of their ages to identify differences among the various age groups in the number of cases with HAV Ab seropositivity. Significant intergroup differences were noted in this respect: 21-25 years, 2/152 (1.3%); 26-30 years, 33/245 (13.5%); 31-35 years, 70/148 (47.3%); 36-40 years, 52/79 (65.8%); >40 years, 44/48 (91.7%). CONCLUSION: The number of seropositive cases was low among young healthy personnel: low seropositivity is an emerging risk for vulnerable population. With the increase in the incidence of hepatitis A, healthcare personnel have become a risk population for hepatitis A, as are community residents. Therefore, for healthcare personnel working in hospitals, immunization against HAV should be recommended for personnel younger than 30 years, and serological testing for older personnel.

Behcet's disease (BD) involves multisystem vasculitis of unknown origin. Ocular manifestations of BD mostly include bilateral panuveitis and retinal vasculitis, which are very challenging to treat. Interferon alfa-2a (IFN) has been recently introduced for treating refractory Behcet uveitis, mainly in Germany and Turkey. Nonetheless, there is so far no consensus about the ideal treatment regimen of IFN for Behcet uveitis. We report our experience of IFN treatment in five Korean BD patients with refractory uveitis. All patients complained of oral ulcers; one patient had a positive pathergy test and 2 showed the presence of HLA-B51. Immunosuppressive agents used prior to IFN treatment included cyclosporine and methotrexate. The IFN treatment was commenced with a dose of 6-9 MIU/day for 7 days, adjusted according to individual ocular manifestations, tapered down to 3 MIU three times in a week, and then discontinued. All patients showed positive response to IFN treatment; 50% of them showed complete response without additional major ocular inflammation during the follow-up period. Other BD symptoms also improved after IFN treatment in most cases. After treatment, the relapse rate and the required dose of oral corticosteroid were decreased in most cases, showing a significant steroid-sparing effect. However, the visual acuity was not improved in most cases due to irreversible macular sequelae. Despite the small sample size of this study, we suggest that, in Korean patients, IFN is an effective treatment modality for BD uveitis as was observed in German and Turkish patients.
