1.Studies on the Specific Estradiol Binding Site on Rat Uterine Membranes
Journal of Korean Society of Endocrinology 1996;11(4):510-516
Backgroand: In our previous study, it was demonstrated that estradiol-dependent prostaglandin synthesis may be mediated by cAMP elevation during the process of iplantation in rats. The present study was undertaken to investigate if estradio1, a hydrophobic molecule could interact with uterine plasma membrane, thereby influencing adenylate cyclase and cAMP. Methods: The specific binding of [3H]estradiol to plasma membrane prepared from rat uterus has been identified and characterized. Results: The association of [3H]estradiol to plasma membrane preparations reached equilibrium at 24 hrs. [3H]estradiol binding was directly proportional to the concentration of plasma membrane preparations and its binding was temperature-sensitive. This binding was saturable, reversible and binding site was one type with high affinity(Kd=0.16+0.03 nM) and high binding capacity(Bmax= 2.03 + 0.38pmol/mg protein). The dissociation constant was estimated as 1.6*10(-10)M. In a competition assay, binding was specific for estrogenic compounds. When 100% specific binding was detennined in the presence of 3*10(-6) M diethylstilbestrol, 17B-estradiol and tamoxifen displaced specific binding by 115% and 23%, respectively. Neither progesterone nor cortisol at 500-fold excess displaced the specific binding. Conclusion: These data suggest the presence of specific binding sites on the plasma membrane for estradiol in the rat uterus.

This article reviewed 75 nursing research papers on stroke done since 1990 to 2000 by examining them according to the period of publication or presentation. research design, type of subjects, measurement variables. the intervention outcome of experimental research, and theme of qualitative research. The research were as follows: 1. 26 of 75 studies were composed of master thesis and dissertation of graduate school. There were 53 nonexperimental research. 15 experimental research and 7 qualitative studies design. 2. Stroke patients subject' Characteristic were 44 and Family and Spouses of caregiver support were 28 of total studies. 3. Most measurement instruments used for research were translated and redesigned it into Korean that developed by foreigners, and development measurement instruments used Kang's ADL. 4. Family support and Social support was shown the frequently among correlational research. 5. Methodological research were development of an evaluation tool for the quality of nursing care in stroke patients. caregiver support of development of nursing intervention list. and Home care Nursing Intervention protocol. and development of client selection criteria based on the needs of services to be offered. 6. The experimental research of intervention were mostly education nursing intervention. rehabilitation program on functional recovery. support nursing intervention. and applying a home care protocol on the nursing care intervention. 7. Theme of qualitative research were family experience, home care in family experience, soobal expenence, illness experience. hope of Stroke patients and so on. Phenomenologic methodology and Granded Theory was designed of Qualitative research. On the basis of the above finding the following recommendations are made: 1. It's necessary to develop a reliable and variable measurement tool for stroke patients and family care of stroke patients. 2. It's necessary to study the comparison of Nursing Studies of stroke research abroad, the replication to establish the effect of nursing intervention stroke patients and family care of stroke patients.

PURPOSE: This study aimed to synthesize the caring experiences of Korean family members of patients with dementia through a qualitative meta-synthesis method. METHODS: By searching through nine Korean and English databases, we compared 37 qualitative studies on caring experiences of family members of patients with dementia. The selected studies were synthesized through meta-synthesis, proposed by Sandelowski and Barroso (2007). RESULTS: The meta-synthesis elicited four themes: tough life due to care for patients, changes in relationships, adaptation to caregiver's roles, and new perspectives of life through personal growth. Caregivers were shocked when a sudden diagnosis of dementia was made prior to any preparation on their part. They were tied to their patients all the time and their mind and body got exhausted. Their relationship with patients began to change and they looked at them differently. They experienced conflicts with the other non-caring family members and were alienated from them. They were also socially isolated. However, by building their own care strategies and utilizing social resources, they gradually adapted to their caregiver roles. Finally, they experienced personal growth and acquired a new perspective toward life by accepting their roles and finding meaning in their lives. Shifting the caregiver's centricity from themselves to the patient was the process of becoming human beings who actively constructed their realities while giving meaning to their painful lives and interacting with the environment. CONCLUSION: The results of the study can be useful for nurses in understanding the experiences of caregivers of the patients with dementia and in providing them with practical interventions.

5.The Factors Influencing Quality of Life in Women with Breast Cancer.
Asian Oncology Nursing 2013;13(3):121-127
PURPOSE: The purpose of the study was to identify the influence of hope, resilience, and spousal support on quality of life in women with breast cancer. METHODS: A predictive correlational design was used. The data were collected by questionnaires from a convenience sample of 163 women with breast cancer in 2012. The data were analyzed using descriptive statistics, t-tests, ANOVA, Pearson's Correlation Coefficients, and stepwise multiple regression. RESULTS: Mean age of the participants was 51.5+/-6.39 and 46.0% reported to have stage II at diagnosis and 40.5% were more than 5 years since diagnosis. The quality of life was different by age and type of surgery. Hope, resilience, spousal support, and quality of life were significantly correlated each other (r=.35-.64, p<.01). Quality of life accounted for 23.4% of the variance by resilience, spousal support, and type of surgery. The most important factor was resilience, which explained 18.9% of the variation. CONCLUSION: The results of the study show the importance of resilience in explaining the quality of life in Korean women with breast cancer. Thus, oncology nurses should focus on resilience to develop and implement more effective interventions to improve patients' quality of life.

Hepatoid carcinoma is a rare type of malignant tumor resembling hepatocellular carcinoma that arises in extrahepatic sites.(stomach, lung, ovary, pancreas, bladder and renal pelvis). Hepatoid carcinoma of the ovary is an extremely rare ovarian tumor, first described by Ishikura and Scully in 1987. Histologically it is important to differentiate this entity from other oxyphil tumors of the ovary as it requires aggressive treatment. We have experienced a case of hepatoid carcinoma of the ovary in 69-year-old postmenopausal woman, who has been treated with operation and adjuvant Taxol - cisplatin chemotherapy. We present this case with brief review of literatures.

Journal of Korean Academy of Adult Nursing 2007;19(1):155-165
PURPOSE: The purpose of this study was to determine the relationships of pain cognition, performance status, and hope with health-related quality of life. METHODS: Patients(n=149) with various cancer diagnoses completed the SF-36 standard Korean Version and the Herth Hope Index. The Perceived Meanings of Cancer Pain Inventory was used to measure the cognition dimension of pain, whereas the Brief Pain Inventory Korean version was used to represent the sensory dimension of pain. RESULTS: The patients in the pain group had significant differences in the three dimensions(loss, threat, spiritual awareness) of pain cognition. There were statistically significant negative correlations between the three dimensions(loss, threat, and spiritual awareness) of pain cognitions and SF-36 dimension, and the positive correlations between challenge dimension and SF-36 dimension. Hope had the positive correlation with SF-36 dimensions. CONCLUSION: Pain has a negative impact on health-related quality of life, especially on physical health. However, patients who ascribed more positive meaning to their pain, tended to have a higher quality of life. Therefore, nursing intervention to reinforce the positive aspects of pain cognition is to empower patients to create a sense of control and assume an active role in pain management and quality of life.

PURPOSE: To evaluate differential points of clustered microcalcification in malignant and benign lesions on histopathology and correlate with mammographic findings. MATERIALS AND METHODS: Authors evaluated differential points of malignant and benign calcifications in histopathologically confirmed 24 cases. In two patients, mapping studies and paraffin block mammographic examinations were done to correlate calcification on mammography with histopathologic morphology. RESULT: On histopathology, malignant calcifications were located in ductal lumen, while benign ones were usually located in ductal epithelium(p<0.05). However, associated three benign lesions of the 10 malignant lesions showed still benign calcifications adjacent to proven cancer. The typical malignant calcifications were the shape of lamination, while benign calcifications showed granular and salty on light microscope. In 2 mapping studies, malignant-looking calcifications within the area of predominant benign calcifications yielded atypical ductal hyperplasia. Mammographic pepper, granular, punctate, salty and S-shaped calcifications were correlated with granular and salty calcification on light microscope. Mammographic linear, branching, comma, tadpole and wormiform calcifications were correlated with histopathologic laminated calcification. CONCLUSION: Authors have recognized about characteristics of malignant Vs. benign clustered microcalcifications on histopathology. Authors concluded that if malignant-looking calcification such as linear, branching, comma, tadpole and wormiform are present in an are a of predominant benign calcifications, specimen radiographic correlation and mapping study will be necessary for better demonstration of the atypical ductal hyperplasia, hidden or associated breast cancer.
