Authors experienced a rare adenocarcinoma arising in presacral sacrococcygeal teratoma in a adult and herein reported. The patient was a 52 year old female admitted because of lower abdominal pain for 5 to 6 months. Past and familial history were unremarkable. On rectal examination a mass was palpated 3 cm above the anal verge. The large bowel was displaced by an extrinsic mass but there was no evidence of intrinsic tumor lesion on barium enema, CT was done and showed a large presacral tumor attached to the sacrum. Clinical impression was sacrococcygeal teratoma. Resected tumor mass was a relatively well circumscribed cystic mass, measuring 11 x 11 cm and the cystic content was previously evacuated. Inner surface showed ragged appearance, and focal nodular solid area was noted. On microscopic examination, the tumor revealed the derivatives of three germ layers and main components were tissues of respiratory tract. Sections from the solid area showed a well differentiated adenocarcinoma and with stromal, capsular and perineural invasion. Borderline malignant epithelial lesions are also noted suggesting the pathogenesis and progression of this tumor. There was no recurrence for one year after surgery in the follow up.

PURPOSE: The purpose of this study was to determine the relationship between assessed pain, functional status, and emotional status in elderly women with dementia. METHODS: The method was a descriptive correlational design. Subjects were sampled from 75 elderly women with dementia who were resident in nursing home. and their pain, functional status(physical function, cognitive function), emotional status(depression, agitation) were measured. The collected data were analyzed for correlations between pain and functional status and for emotional status using the SPSS 11.0 statistical program. RESULTS: The pain degree of the aged women in dementia were as follows; between 0 and 27 points, average 4.04 points, which was a possible point extent. Looking at the grades in detail items, the wry face expression was shown highest, an average of 0.84 points. The relation with cognitive function was(r=-.259, p<.025) a minus relation. And the relation with physical function was (r=.406, p<.001) a plus one. The relation with depression was (r=.462, p<.001), plus one. And (r=.592, p<.001) a plus relation was found with agitation. CONCLUSION: Pain is associated with impaired functional and emotional status. Major efforts are needed to improve nursing assessment and management of pain in this cognitive impaired population.

We present an ultrastructure of an incidentally found renomedullary interstitial tumor also called as medullary fibroma in a 77 year-old female who had a metastatic adenocarcinoma of colon to the ureter. This tumor was a small and grayish white nodule in renal medulla, measuring 0.4 x 0.4 cm. Microscopically the tumor composed of spindle cells, with some vacuolation and intercellular collagen fibers. The electron microscopic observation of the spindle cells reveal that nuclei are spindle to oval shape and cytoplasm contain abundant rough endoplasmic reticulum, polyribosome without microfilaments and cisterna like structures supporting that the renomedullary interstitial cell tumor is renal interstitial cell origin than fibroblasts.

Since introduction of venous flap in 1980, many experimental studies and clinical applications of various kinds of venous flaps were reported. Venous flap has the following advantages : (1) nonbulky and goo-quality of flap (2) long & large vascular pedicle (3) easy & rapid elevation of flap (4) no sacrifice of major arteries (5) a single operative field. But, we also have some disadvantages of difficult handling of the pliable veins and the tmcertainty of flap survival. For the better result we had to design the size of the flap larger than that of defect and increase the number of draining vein to reduce the postoperative edema of the flap. We have treated the defects of soft tissue of the hand using free arterialized venous flap from the flexor aspect of the forearm & had an excellent results.

BACKGROUND: Radiation has been used in t,he medical field of dragnosis and treatment. There is widely used ionizing radiat:ion such as naturally occuring r-rays or machine-made X-ray. This radiation is able to induce the structural and functional alterations of the mammalian cells. But we have few detailed reports on the effects of radiation on epidermal cells and their immune functions. OBJECTIVE: This study was performed to investigate the effect of radiation on cultured human keratinocytes and melanocytes. MATERIALS AND METHODS: Cultured human keratinocytes and melanocytes were irradiated with 2,6, l0Gy from a Co saurce and stimulated by 100 U/ml of ekratinocyte immediately after irradiation. We investigated cell numbers and morphological changes, DNA synthesis and HLA-DR antigen expression. RESULTS: After exposure to r-ray, the proliferation of keratinocytes and melanocytes decreased in a time and dose dependent fashion to each control group. Tliey showed decreased density, a larger size and a round appearance after radiation exposure and an especially shortened and decreased number of dendrites in the melanocytes. In DNA synthesis counted using [H]-thymidine incorporation, the keratinocvtes decreased values in a dose depen(lent manner at 24 and 72 hours after irradiation but no differense was observed at 168 hours. In melanocytes, there was a greater decrease than that of keratinocytes. The melanin content/cell in all radiation exposed groups increased in a time and dose dependent fashion t,o each contr ol group. HLA-DR antigen expression on keratinocytes after radiat,ion exposure decreased to the control group, but there were no significant differences acccirding to the dose of radiation, And there were no significant diifferences of HLA-DR antigen expression on the melanocytes betweer. controls and the radiation exposed groups. CONCLUSION: Antiproliferative activity was dependent on the exposure time and dose of r-ray exposure. According to the time after radiation exposure, melanogenic activity was stimulated. The expression of HLA-DR, antigen decreased in keratinocyte after radiation exposure but there was no decrease in melanocytes.

PURPOSE: This study was done to identify the level of stress, coping, and depression among hemopoietic stem cell transplantation patients who received care in an outpatient center. METHOD: Data were collected from 81 patients who underwent hemopoietic stem cell transplantation at C University S Hospital between August 2005 and February 2006. RESULTS: Stress and depression were significantly higher following hemopoietic stem cell transplantation in women, and in patients who were worse off financially or who were in bad health. The highest item of stress was 'economic burden for treatment'. There were significantly higher levels of emotion-focused coping among patients who had a spouse and who received motivation from the doctor. The highest item for problem-focused coping was 'try to look at the bright side of life'. The highest items for emotion-focused coping were to 'have faith that treatment will be finished quickly' and 'believe that your situation will improve'. Stress was significantly correlated with depression among these patients. CONCLUSION: It is necessary to develop nursing interventions to enhance positive coping and to decrease stress and depression among patients who have a hemopoietic stem cell transplantation.

Perforator free flap (PFF) is currently a major reconstructive option for soft tissue reconstruction in adults. Although PFFs have been used commonly, most reconstructive surgeons still hesitate to perform PFFs in children. The main cause of concern is the perceived high failure rate related to the small diameter of children's perforator vessels. We present 8 consecutive cases of successful transfer of thoracodorsal artery (TDA) & anterolateral thigh (ALT) perforator flap in children. Between 2003 and 2005, 8 children(4 to 13 years old) with soft tissue defects of the extremities were reconstructed with TDA & ALT PFFs. All flaps completely survived. There were no problems relating to vascular spasm or occlusion. Range of motion of reconstructed extremities were fully recovered. Among 8 patients, only 1 patient was performed an additional flap thinning procedure. 8 cases of TDA & ALT perforator flaps were successfully transferred in children. PFF is an excellent option in reconstruction of children as well as in adults because of its thinness, long pedicle length, least donor site morbidity and acceptable donor site scar.

N,N-Diethylnitrosamine (DEN) has been proved to have carcinogenic potential in the initiation or promotion stage and the transformed cells proliferate to form preneoplastic nodules which are positive for placental form of glutathione S-transferase (GST-P). E-Cadherin, a member of the cadherin family, is expressed in epithelial cells. To evaluate the role of adhesion molecules (E-Cadherin, alpha-catenin, and beta-catenin), which have not been well understood in carcinogenesis, we investigated the changes of E-cadherin, alpha-Catenin and beta-Catenins by immunohistochemistry and immunoblotting in DEN-induced hepatocarcinogenesis of rat liver. In addition, the sequential analysis of histopathology and the expression of GST-P were also examined. Immunoreactive areas for GST-P were gradually increased from early period of carcinogenesis and strong GST-P positive foci were noted in various lesions, especially in the clear cell and eosinophilic cell nodules. Immunohistochemically, the E-Cadherin expression was increased in DEN-treated preneoplastic nodules in 4 and 10 weeks and hepatocellular carcinomas displayed relatively reduced expression compared with the hyperplastic nodules. But alpha- and beta-catenin expression was increased in hyperplastic nodules and hepatocellular carcinomas. Immunoblotting studies revealed that the level of alpha-catenin (cytosol and membranous fraction) was overexpressed in hyperplastic nodules as well as hepatocellular carcinomas, which showed markedly increased expression. The membranous fraction of beta-catenin was markedly increased in 10 weeks of DEN treatment and slightly reduced in hepatocellular carcinomas. These findings suggest that during DEN-induced hepatocarcinogenesis, the clear cell and eosinophilic cell nodules expressing GST-P in their cytoplasm are early transformed cell nodules. The altered expression of E-Cadherin and catenins is closely related with tumor propagation. Loss or reduced expression of E-cadherin may play a role in the progression of late hyperplastic nodule to hepatocellular carcinoma in DEN-induced rat hepato carcinogenesis.

The mechanism of the disease such as artherosclerosis is easily elucidated by the comparison among cells isolated from each aorta of knockout mouse and wild type mouse, respectively. This study was aimed at effectively harvesting the endothelial and smooth muscle cells from 4~6 weeks old wild type C57BL/6J mouse aorta. The tunica adventitia was completely removed to get the aortic tissues only consisting of the tunica intima and the tunica media under the stereoscope. These aortic tissues were treated with type I collagenase or type II collagenase solution, respectively, and then the endothelial or smooth muscle cell was isolated. CD31 marker of the endothelial cell and alphasmooth muscle actin marker of the smooth muscle cell were identified with confocal microscope. The percentages of the labelled cells by each marker represented the extent of purification of endothelial or smooth muscle cells, respectively, for harvested cells according to the collagenase solutions. 70~80% of culture vessel was covered with the endothelial cells 10 days after the treatment of the type I collagenase solution, while 40~50% of culture vessel covering with the cells after the treatment of the type II collagenase solution. 70~80% of culture vessel was covered with the smooth muscle cell regardless of the type of the collagenase solution on the 13th day. Percentages of the CD31 positive cells after the treatment with the type I or the type II collagenase solution was 91.1+/-.865%** and 86.4+/-.641%, respectively (**p <0.05, n=5). Percentages of the alphasmooth muscle actin labelled cells after the treatment with the type I or the type II collagenase solution were 87.9+/-.713% and 86.6+/-.778%, respectively, and these values were not significantly different. Taken together, the aortic tissues using the type I collagenase solution comparing with using the type II collagenase solution were much more effective in the isolation of the endothelial cells
