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.

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.

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.

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.

The purpose of this study was to assess the use of food materials at elementary school in Busan area and provide school meal management with basic data to improvement of guideline. A survey was done by e-mail with a set of questionnaires, which was responeded by 122 dietitians in elementary school foodservice. The results were as follows; Sixty percent of the dietitians though to the general imported food materials had to use. Regarding mean score of using the imported food materials; safety was 2.12/5.00, freshness 2.48/5.00, sanitation 2.68/5.00, nutrition 2.73/5.00, preference 2.93/5.00, external form 3.09/5.00, package 3.12/5.00, and price 3.63/5.00. Thirty seven percent of the dietitians had purchase the pro-environment farm products(PEFPs) and 32.0% of them purchased those products for the students' health. But 52.4% could not purchase to the PEFPs because of expensive price. They had negative opinions about deficient supplying of PEFPs 4.51/5.00, too expensive price 4.34/5.00, and the truth or false in source of PEFPs 3.96/5.00. Most of them perceived that using the PEFPs had to apply the step by step. Among of them, 33.9% had the knowledge of PEFPs, but 16.4 of them did not know to the PEPPs. 57.4% of them hoped to purchase the food materials through a center of supporting school meal servcie(it called non-profit-making organizations).

PURPOSE: To describe the performance in the health-promoting lifestyle and to identify the major factors affecting the health-promoting relationships between self care behaviors and health promoting lifestyle profile in patients with pulmonary tuberculosis. METHOD: A convenience sample for this study was 172 pulmonary tuberculosis patients who have taken TB medications in urban city. The HPLP-ll was selected to measure the concept of health- promoting lifestyle because of the number of research studies conducted using both the original HPLP and the revised HPLP-ll. The statistical methods used in this study were t-test, ANOVA, Pearson correlations, and multiple regression. RESULT: The differences of the HPLP-ll were found to have a significance of age, marital status, education level, and health service center. The level of self care behaviors was related positively to the level of health promoting lifestyle and their subcategories. Based on stepwise multiple regression analysis, the model that predicted factors included self care behaviors, age, health service center and education. CONCLUSION: After decades of decreasing rates, TB has reemerged as a serious national problem in Korea. The careful clinical management and more national concern of TB may help to improve the outcomes of many patients. The findings of this study suggest that TB patients who are more fulfilled in health-promoting lifestyles and self-care behaviors may be able to make better decisions regarding positive health-promoting behaviors.

Spinal epidural abscesses were evaluated using Gadolinium-enhanced magnetic resonance imaging (MRI) in 19 surgically and clinically confirmed cases, including 13 with tuberculous spondylitis and 6 with pyogenic spondylitis. We observed rim enhancement patterns in 10 patients and diffuse enhancement patterns in 9 patients. The spread patterns were localized to ventral or dorsal epidural space and encircled entire epidural space. We conclude that rim enhancement indicates abscess and diffuse enhancement indicates granulation tissue and fibrosis. Tuberculous epidural abscess spreads to ventral epidural space and pyogenic epidural abscess encircles entire epidural space.

PURPOSE: The purpose of this study was to evaluate the spectrum of MR characteristics of cystic acoustic neurinomas and to correlate with pathologic findings. MATERIALS AND METHODS: We retrospectively reviewed the MR findings of 12 patients with cystic acoustic neurinomas. The signal intensity and enhancement pattern of the cystic components as well as the location relative to the tumors were analyzed. RESULTS: A total of 30 cysts were found in 15 acoustic neurinomas;28 were intratumoral cysts and the remaining two were extratumoral cysts. The signal intensity of all 28 intratumoral cysts was higher than that of CSF on Tl-weighted images, and isointense to CSF on T2-weighted images, while the signal intensity of the two extratumoral cysts was same as CSF on both Tl-weighted and T2-weighted images. Rim enhancement was seen in 27 of 28 intratumoral cysts but in none of the two extratumoral cysts. CONCLUSION: We concluded that intratumoral cyst was due to tumoral necrosis, hemorrhage or degenerative change and extratumoral cyst due to secondary arachnoid cyst formation.
