The origin of the stromal cell of cerebellar hemangioblastoma has long been studied electron microscopically and immunohistochemically. The results and theories about the stromal cell origin are variable and plentiful. However, the exact origin of the stromal cell remains controversial. The present study is aimed to elucidate the nature of the stromal cell of cerebellar hemangioblastoma. Ten cases of hemangioblastoma in Severance Hospital were used for immunohistochemical analysis of the stromal cell. The immunohistochemical staining of GFAP, S-100 protein, NSE, alpha-l-antichymottypsin, cytokeratin, CD 68, factor VIII related antigen, and synaptophysin were performed. The results were as follows; GFAP and S-100 protein were stained mainly but weakly in bellar capillary spindle cell and cellular process. NSE was stained mainly in foam cells, and 6 cases among them revealed strong reaction. ct-l-antichymotrypsin was stained in a few foam cells of 5 cases. Cytokeratin, CD 68, factor VIII related antigen, and synaptophysin showed negative reaction. Based on these results, it is considered that the origin of the stromal cell is histiocytic or neurogenic rather than glial. The weak positivity of GFAP and S-100 protein may support the neurogeriic origin but ct-l-antichymotrypsin positivity does not support the possibility. The positivity of GAP and S-100 protein supports the phagocytic action of histiocytic cell and suggests histiocytic origin rather than neurogenic.

Fisting is an uncommon sexual activity, and death due to fisting is very rare. In the present report, we describe a case of a woman who died from fisting by her male partner. A 38-year-old woman went to a motel with a man after consuming alcohol, and there they kissed each other. As desired by woman, the man inserted his fingers into her vagina and anus, and later inserted his fist and forearm into her vagina and anus. After 20-30 minutes of fisting, the woman became unconscious and died. The autopsy confirmed the presence of perineal and vaginal lacerations with massive internal pelvic soft tissue injury with uterine artery rupture. A partial tear was noted at the rectosigmoid junction. The cause of death was hypovolemic shock due to uterine artery rupture. Following court trials, the assailant was sentenced to 4 years of imprisonment for the felony of inflicting bodily injury resulting in death.

PURPOSE: This study was done to identify and compare nursing performance including job stress, emotional labor and burnout between nurses who work in comprehensive nursing care service wards and general wards. METHODS: Participants were 187 nurses working in a general hospital in Busan which provides comprehensive nursing care service (comprehensive nursing care service ward: 95, general ward: 92). Data were collected using questionnaires and analyzed using descriptive statistics, χ² test, t-test, ANOVA, and multiple regression with the SPSS/WIN 23.0 program. RESULTS: There was no significant difference in the variables between comprehensive nursing care service ward nurses and general ward nurses. Factors influencing burnout were emotional labor in comprehensive nursing care service ward nurses while job stress and emotional labor were the factors influencing burnout in general ward nurses. CONCLUSION: The findings of this study indicate that comprehensive nursing care service can be a positive delivery system for nurses. Therefore, there is a need for strategies to integrate comprehensive nursing care service systematically.

OBJECTIVE: This study was conducted to examine the effect of vitrification on the survival and in vitro development of mice 1-cell zygotes. METHOD: Effects of exposure to vitrification solution and vitrification, with different concentrations of the cryoprotectant solution, were examined. The 1-cell zygotes were also subjected to a slow freezing- thawing method to compare with vitrification method. Solution composed of ethylene glycol (6.0 M, 5.0 M, 4.0 M) and sucrose (1.0 M) were used as cryopropectant. The experiments employed the method loading the embryos on electron microscope grids. RESULTS: I. The effects of exposure in vitrification solution 1-cell zygotes were non-toxic at all concentrations of the vitrification solution showing the survival rate between 88.1% and 97.5%. Development into 2-cell was more successful in the higher concentrations of the vitrification solution. Therefore, higher concentrations of the vitirification solution do not seem to cause any problems in vitrification procedure. II. The effects of vitrification method 1-cell zygotes showed the survival rate between 78.8% and 92.4%. The lowest and the highest survival rate was observed in the 6.0 M and 4.0 M vitrification solution, respectively. 2-cell development rates varied from 77.6% to 91.3%. Blastocyst development rate was shown highest in 5.0 M and the lowest in 4.0 M solution. Therefore, the highest 2-cell and blastocyst development rate was observed in 5.0 M solution. III. Comparison of vitrification and slow freezing-thawing method on 1-cell zygotes This experiment showed that 1-cell zygotes had the highest survival and development rates in 5.0 M vitrification solution. Vitrified group of 1-cell zygotes, in the 5.0 M vitrification solution, were compared with the group processed in slow freezing-thawing method. The development rate into 2-cell and blastocyst as well as the survival rate were higher in the vitrified group than in the slowly freezed group. CONCLUSION: 1. The results demonstrate that the best cryoprotectant is a 5.0 M vitrification solution for 1-cell zygotes. 2. Vitrification method significantly increases the survival rate of the 1-cell zygote and its development into 2-cell and blastocyst. Equilibration and exposure time during the vitrification was remarkerbly short in this experiment. Total time, from the exposure to vitirification solution to storage in the liquid nitrogen, was taken only 90 seconds. In contrast, the slow freezing-thawing method have taken more than four hours. Taken together, we presume that the overall time used for the procedure contributes to the results as an important parameter. 3. The loading of 1-cell zygotes on the EM grid is technically more simple and takes less time than the straw or cryo vial method.

OBJECTIVE: The aims of this study were to analyze the natural history of patients with pseudomyxoma peritonei originated from mucinous ovarian tumor, evaluate clinical and pathologic variables, and review our experience with available therapeutic modalities. METHODS: Six patients were treated for pseudomyxoma peritonei originating from mucinous ovarian tumor at Severance Hospital between 1990 and 1998. The data were collected retrospectively and all charts were reviewed RESULTS: The mean age at diagnosis was 51 years, and most common symptoms were abdominal distension. Pseudomyxoma peritonei was found in association with five mucinous ovarian tumors of borderline malignancy, and one ovarian mucinous adenoma. All patients underwent surgical staging and cytoreduction, three patients received postoperative adjuvant chemotherapy and, of these, two developed recurrence. With respect to survival, all patients were alive, four were alive and free of disease, two were alive with disease at the end point of study. CONCLUSION: Pseudomyxoma peritonei is commonly associated with borderline mucinous ovarian tumors, and is a frequently relapsing and protracted disease. But aggressive and repeated debulking surgery is recommended for long survival.

Changes in CTB labeled motor neurons of the spinal cord were observed after the induction of peripheral neuropathy by ligation of the tibial nerve. Rats were anesthetized and the tibial nerve was ligated with 3-0 silk. The rats were separated into three groups based on the length of time the tibial nerve was ligated (1, 2, or 4 weeks). After the ligation procedures were complete, the tibial nerve stumps were soaked in CTB solution. Tibial nerve segments and the spinal cord were then observed. In the control and experimental groups, CTB-labeled neurons formed a discrete population that was concentrated primarily at the L5 level, while the contributions from L4 and L6 were minor. According to the distributions, CTB-labeled neurons were divided into rostral and caudal groups. A selective decrease of CTB-labeled neurons was observed only in the caudal group, extending from the rostral L5 to one-half of the rostral L6. The total numbers of CTB-labeled motor neurons were 2,160+/-169.3, 1,002+/-245.1, 587.5+/-346.5, and 1,728+/-402.6 in the control group, 1 week group, 2 week group, and 4 week group, respectively. The selective decrease of CTB-labeled neurons in the caudal division was responsible for the decrease in the total number of labeled neurons in all groups. Following peripheral neuropathy caused by ligation of the tibial nerve, CTB-labeled neurons in the spinal cord decreased selectively. These results may provide important neuroanatomical data regarding the effects of peripheral neuropathy by ligation of the tibial nerve.

PURPOSE: The aim of this study was to identify the correlation between spiritual well-being and mental health and to examine the effect of spiritual well-being on mental health in nursing students. METHODS: Between October 2011 and November 2012 nursing students (n=193) in 2 universities in 2 cities completed measures of spiritual well-being and mental health. Data were collected using questionnaires and analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and multiple regression with the SPSS/Win 20.0 program. RESULTS: All variables correlated significantly with each other in the positive direction: mental health was correlated with existential well-being (r=.72) and religious spiritual well-being (r=.23). The factor influencing mental health was existential well-being (beta=.70, p<.001). Existential well-being explained 51.0% of nursing students' mental health. CONCLUSION: The results of the study indicate that spiritual well-being of nursing students is related to mental health. Especially, existential well-being has a major effect on mental health in nursing students. Therefore, it is necessary to develop strategies which strengthen existential well-being in order to improve perspective nursing students.
