PURPOSE: This study was done to explore the experience process for depression in elderly women living alone. METHODS: Data was analyzed using Strauss and Corbin's Grounded theory. The twelve participants were elderly women living alone, aged 65 to 80 years. RESULTS: From the participants' statements, 116 concepts, 43 sub-categories and 16 categories were extracted by an open coding process. Core category was 'wandering in a waste land'. The experience process leading to depression in elderly women living alone had 4 phases: loss, emptiness, struggle and response. CONCLUSION: The findings in this study on the experience of depression in elderly women living alone can be used for evidence in a detailed assessment, early detection and prevention of depression in elderly women living alone.

PURPOSE: The aim of this study was to evaluate the effects of tailored case management using a gatekeeper on depression and life satisfaction in the single-household elderly population. METHODS: The design of Quasi experiment was applied to compare the variables before and after the management. Ninety-seven people who had depression categorized by the Korean Geriatric Depression Scale. RESULTS: Depression (t=11.22, p<.001) and life satisfaction (t=-5.36, p<.001) were improved after management in comparison to the results of pre-tests, and the differences were statistically significant. The difference in the pre-test and post-test scores of the support system (chi2=13.89, p<.001) were significant, while the differences in the perception of depression (chi2=.02, p=.891) and coping methods (chi2=.34, p=.558) were not statistically significant. CONCLUSION: Tailored case management using a gatekeeper is effective to reduce the degree of depression and improve life satisfaction in the single-household elderly population having depression. This study offers a model of individualized as well as systemic mental health care for the community of single-house hold elderly people as an effective means for prevention of and early intervention in depression.

OBJECTIVE: Human embryonic stem (ES) cells have a great potential in regenerative medicine and tissue engineering. The human ES cells could be differentiated into specific cell types by treatments of growth factors and alterations of gene expressions. However, the efficacy of guided differentiation and isolation of specific cells are still low. In this study, we characterized isolated cells from differentiated human ES cells by magnetic activated cell sorting (MACS) system using specific antibodies to cell surface markers. METHODS: The undifferentiated hES cells (Miz-hESC4) were sub-cultured by mechanical isolation of colonies and embryoid bodies were spontaneously differentiated with DMEM containing 10% FBS for 2 weeks. The differentiated cells were isolated to positive and negative cells with MACS system using CD34, human epithelial antigen (HEA) and human fibroblast (HFB) antibodies, respectively. Observation of morphological changes and analysis of marker genes expression were performed during further culture of MACS isolated cells for 4 weeks. RESULTS: Morphology of the CD34 positive cells was firstly round, and then it was changed to small polygonal shape after further culture. The HEA positive cells showed large polygonal, and the HFB positive spindle shape. In RT-PCR analysis of marker genes, the CD34 and HFB positive cells expressed endodermal and mesodermal genes, and HEA positive cells expressed ectodermal genes such as NESTIN and NF68KD. The marker genes expression pattern of CD34 positive cells changed during the extension of culture time. CONCLUSION: Our results showed the possibility of successful isolation of specific cells by MACS system from undirected differentiated human ES cells. Thus, MACS system and marker antibodies for specific cell types might be useful for guided differentiation and isolation of specific cells from human ES cells.

OBJECTIVE: The aim of this study was to investigate whether embryonic stem (ES) cells can be established from isolated blastomeres of mouse embryos. METHODS: Blastomeres were separated from mouse (C57Bl/6J) 2- or 4-cell embryos. Isolated blastomeres or whole 4-cell embryos were co-cultured with mitosis-arrested STO feeder cells in DMEM supplemented with recombinant murine leukemia inhibitory factor and ES-qualified fetal bovine serum. After the tentative ES cell lines were maintained from isolated blastomeres or whole embryos, some of them were frozen and the others were sub-cultured continually. Characteristics of tentative ES cell lines as were evaluated for specific gene expressions with immunocytochemistry and RT-PCR. RESULTS: One ES cell line (3.0%) was established from isolated blastomere of 2-cell embryo and one cell line (4.0%) from isolated two blastomeres of 4-cell embryo. And five cell lines (16.7%) were established from whole 4-cell embryos. Both cell lines from isolated blastomere and whole embryo expressed mouse ES cells specific markers such as SSEA-1, Oct-4 and alkaline phosphatase. Marker genes of three germ layers were expressed from embryoid bodies of both cell lines. CONCLUSION: This study suggests that mouse ES cells could be established from isolated blastomeres, although the efficiency is lower than whole embryos. This animal model could be applied to establishment of autologous human ES cells from biopsied blastomeres of preimplantation embryos in human IVF-ET program.

Kikuchi-Fujimoto disease (KFD), also known as histiocytic necrotizing lymphadenitis, is common in young Asian women under the age of 30, and is usually characterized by fever, myalgia, fatigue, and cervical lymphadenopathy. Because patients with KFD often present with necrotic lesions that are also features of lymph node metastasis, ipsilateral or bilateral lymph node enlargement in head and neck cancer patients can be disguised as lymph node metastasis. We present an unusual case of KFD mimicking bilateral metastatic papillary carcinoma of the thyroid. This study emphasizes that KFD should be considered when diagnosing lymph nodes with necrotic lesions but without malignant cells in young women.

We performed this study to evaluate the spectrum of etiologic microorganisms and antibiotic sensitivity of current microorganisms in external eye diseases. From 1992 to 1996, 967 specimens were obtained in cases of suspected microbial infection of external eye disease. Antibiotic sensitivity test was done by disk diffusion method. Among 967 specimens, 339(35%) were culture positive. Of the positive cultures, Gram positive organisms were cultured in 222(65.5%)specimens, Gram negative organisms in 101(29.8%) and fungi in 12(3.5%). In Gram positive bacteria, coagulase negative staphylococcus was the most commonly isolated organism(51.7%). In Gram negative organisms, Pseudomonas aeruginosa was predominant(47.4%). The antibiotic resistant rate of S. aureus(54 strains) was 96% to penicillin, 69% to genatamicin, and 5 strains(9%) showed resistance to ciprofloxacin. Coagulase negative staphylococcus(89 strains) showed high resistance to penicillin(91%), gentamicin(64%), and ciprofloxacin(13%). P. aeruginosa(36 strains) represented 11% of resistance to gentamicin and 1 strain showed resistance to ciprofloxacin. From these results the common patholoic organisms showed high resistance rate to clinically used antibiotics, even to fluoroquinolones. Thus, careful use of topical antibiotics, even to fluoroquinolones. Thus, careful use of topical antibiotics according to principles of antibiotic therapy is required.

The present study was aimed at investigating the molecular regulation of the renin- angiotensin system (RAS) in two-kidney, one clip (2K1C) hypertension. The expression of renin, angiotensinogen and angiotensin II receptor genes was determined by Northern blot analysis in rats made 2K1C hypertensive for 2 or 4 weeks. The expression of renin gene was increased in the clipped kidney and decreased in the contralateral non-clipped kidney at weeks 2 and 4. The expression of angiotensinogen gene was not significantly altered at week 2, but increased at week 4 in the clipped kidney. However, it was not significantly altered in the contralateral kidney either at week 2 or 4. Nor was the expression of angiotensinogen gene significantly altered in the liver either at week 2 or 4. On the other hand, the expression of angiotensin II receptor gene was decreased at week 2, and increased at week 4 in the clipped kidney, whereas it was not significantly changed in the contralateral kidney either at week 2 or 4. In the liver, the expression of angiotensin II receptor gene was not significantly altered at week 2, but decreased at week 4. These results suggest that the components of RAS are transcriptionally regulated in 2K1C hypertension in a manner dependent on tissues and duration of hypertension.

Treatment methods of mandibular condylar fracture were conservative and surgical method. Surgical method of mandibular high condylar fracture was very difficult because approach and internal fixation of small size fracture fragment were difficult. So there is a tendency to select conservative method over surgical method for guiding a stable occlusion and avoiding TMJ disorder and growth disturbance, minimizing pain and deviation during function. But, in case of mandibular high condylar fracture patient who has no biting teeth on posterior teeth area, guiding a stable occlusion and conservative functional treatment were very difficult. In this case, patient was 62years old male. He had fracture of mandibular symphysis, right mandibular body, left mandibular high condyle. We treated the patient for mandibular symphysis and right mandibular body fracture area with surgical method. But left mandibular high condylar fracture area was difficult to treat with surgical method. So we selected a conservative functional method on left mandibular high condylar fracture area. We intended recovery of vertical dimension and stable occlusion with implantation of immediate provisional implant on maxillar and mandibular posterior teeth area, and temporary crown. And then patient did mandibular functional movement and his mandibular function was recoverd.

Purpose: To explore the scope and method of applying standardized nursing terminologies to nursing diagnosis and problems used in nursing practice. Methods: A descriptive study was done with a retrospective analysis of the nursing records of 141,420 patients that were hospitalized in 4 tertiary hospitals. The nursing diagnosis and problems collected from the records were standardized, and the standardized nursing diagnosis and problems cross mapped with NANDA-I, confirmed in a nursing focus group. Results: 65 (67.7%) of the 96 standardized nursing diagnosis and problems were equal with NANDA-I and included in the 10 domains of NANDA-I. Among 86 nursing diagnosis and problems excluded from the cross mapping with NANDA-I, the 63 terms (73.3%) related to surgery/procedure were the most common. Conclusion It is meaningful that multi-tertiary hospital nursing diagnosis and problems were standardized and cross mapping with standard nursing terminologies was performed. As for the method of applying standardized nursing terminologies in nursing practice, it is appropriate to use several standardized nursing terminologies complementarily.
