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: 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.

The purpose of this study was to develop the CORE Program for sex offenders and to determine its effectiveness. The CORE Program was designed with an aim to achieve cognitive restructuring, improve the ability to empathize in interpersonal relationships, and enhance self-esteem and intimacy. We conducted this program over 48 sessions for 28 sex offenders. The effectiveness of the program was evaluated using the Interpersonal Responsiveness Index (IRI), Self-esteem Questionnaire (SEQ), UCLA Loneliness Scale (UCLALS), Coping Using Sex Inventory (CUSI), Rape Myth Acceptance Scale (RMAS), and Wilson's Sex Fantasy Questionnaire (WSFQ). The data were analyzed using paired t-tests. Our results showed no significant changes in the SEQ, UCLALS, and IRI scores after the treatment program. However, the scores for the CUSI, RMAS, and WSFQ significantly improved after this program. In this paper, we demonstrate the effectiveness of the CORE Program for sex offenders. We also discuss the limitations of our study and provide suggestions for future research. Our findings indicate that this treatment program should be provided to sex offenders for preventing recidivism.

PURPOSE: This study was conducted to identify the factors influencing health promotion behaviors. METHODS: The subjects were 200 students sampled from the population that attend four universities in G and J city. Data were collected with a questionnaire and were analyzed by t-test, ANOVA, correlation, and stepwise multiple regression. RESULTS: The mean age of subjects was 21. Family function and self-efficacy were identified as determinants of health promotion behaviors, which explained 53% of the total variances of health promotion behavior. CONCLUSION: The findings provide evidence to help health assessment and activity related to the health promotion behavior of university students.

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: To compare lumbar disc changes between initial lumbar spine (L-spine) MRI and follow-up (f/u) MRI that were performed due to recurred backaches. MATERIALS AND METHODS: A total 50 patients who had undergone f/u L-spine MRI were retrospectively reviewed. Five discs (L1-S1) were surveyed in each f/u MRI. Lumbar disc changes were defined as no change, aggravations, or improvements compared to initial disc states. These states were defined on the basis of morphologic status and disc levels. RESULTS: In a total of 250 discs in 50 patients, 31 discs (12.4%) showed morphologic changes of disc lesions, whereas 219 discs (87.6 %) showed no changes. Among the 31 disc lesions, 24 were aggravated and 7 were partially improved. And on the basis of disc status, initially abnormal discs revealed any morphologic changes of the degree of disc herniation. A total of 33.3% of the morphologic changes are noted in initially extruded discs. Fifteen morphologic changes of disc lesions were located at the L4-5 level. CONCLUSION: Our results suggest that correlations between lumbar disc herniations and back pain symptoms are limited, and that evaluations of extra disc lesions are required.

PURPOSE: Aggressive chemotherapy and bone marrow transplantation have a large demand for platelet concentrate and packed RBC transfusion. Febrile nonhemolytic transfusion reactions are an immunologically mediated reaction involving plasma in the recipient and the white blood cells in the donor. This study was performed to understand the role of cytokines and factors associated with febrile nonhemolytic transfusion reaction to transfused blood. METHODS: Samples were obtained from 42 transfused blood(36 packed RBC, 6 platelet concentrates). Initial WBC count, pH, LDH, irradiation, use of filter and storage time were checked. The serum levels of Interleukin-1beta(IL-1beta), Tumor necrosis factor alpha(TNFalpha) and Interleukin-6(IL-6) were measured by ELISA method using commercial kit for each cytokines. Transfusion reactions, including fever, were recorded in all cases. RESULTS: With the storage time of blood products longer in duration, the serum levels of IL-1beta, TNFalpha and IL-6 were significantly higher(P<0.05). The serum levels of IL-1beta, TNFalpha and IL-6 increased significantly as these blood products were more contaminated with WBC>3000/mm3(P< 0.05). There was no relationship between cytokines and LDH, pH respectively. Febrile reaction was noted in 2.3%(1/42). CONCLUSION: Transfusion reactions are not always the result of an antigen-antibody reaction, but could be caused by the administration of large amounts of cytokines in the plasma. The longer storage times of blood products was associated with frequency of febrile transfusion reactions. We recommend fresh blood transfusion and reduction of WBC before storage because it abrogates cytokine accumulation and dramatically lowers the rate of febrile transfusion reaction.

Socialization is the process of moving from one social role to another by gaining knowledge, skills and behaviors to participate in a group. Nurses who graduate from nursing school, enter the work force, and develop a career undergo socialization as they become insiders in the hospital. This study was designed to identify experiences of the nurses' socialization process in the hospital setting. The subjects were 6 nurses. Data were collected by recording and transcribing interviews and analyzed in the framework of grounded theory as mapped out by Strauss and Corbin(1990). The core category in the analysis of the experiences of nurses' socialization process was "being beyond". In the process of data analysis, 22 categories were identified. These categories were again grouped into 13. Based upon these results, it is recommended that development of resocialization models to establish nursing identity are necessary.
