This study aimed at assessing the usefulness of paraffin wax sections for demonstration of ER(estrogen receptor) and PR(progesterone receptor), using brief microwave processing rather than proteolytic predigestion. The receptor status of a breast cancer is often into consideration when planning treatment nowadays. As biochemical receptor assays require large amount of fresh tumor tissue and are not always available for all tumors, pathologists are now increasingly asked to provide a service for the assessment of the receptor status in tissue routine sections. Until recently, immunohistochemical demonstration of receptors was used in frozen sections. Therefore, routinely processed paraffin wax sections of 25 cases of breast carcinoma with known ER and PR concentrations, estimated by the standard DCC(dextran-coated charcoal) biochemical assay, were examined using the ABC immunoperoxidase technique. The results were assessed semiquantitably, using a five grade scoring system. Of the 25 cases examined, with DCC cutoff point being <10 fmol,71% and 75% in positivity of each ER, PR receptor is concordant. Statistic analysis demonstrates high relationship between scoring system of IH method and DCC value in ER (R=0.6061, p=0.001) and PR (R=0.5832, p=0.001). The IH method can provide easily assessed reliable positive information about ER, PR status of breast carcinoma using routinely processed paraffin wax sections.

A case of supracardiac type of total anomalous pulmonary venous return into the superior vena cava is reported which was successfully diagnosed using spiral CT and three-dimensional image reconstruction. Spiral CT with three-dimensional reconstruction is non-invasive method of visualizing the vascular system and in some instances can replace conventional angiography in pediatric patients.

The double-chambered right ventricle is congenital or acquired cardiac anomaly, which is characterized by aberrent hypertrophied muscular bands that divide the right ventriclar cavity into two different pressure chamber. This anomaly can complicate the natural history of patient with isolated ventricular septal defect. We experienced two cases of cases of acquired DCRV, which confirmed by two separate cardiac catherterization and angiography. The purpose of this report is to show that the aberrant muscular bands may be nonobstructive in early infancy and that the obstructive effect is developed with time as the bands become progressively more hypertrophied.

Pulmonary tumors exhibiting neuroendocrine differentiation are classified as typical carcinoid, atypical carcinoid, and small cell lung carcinoma(SCLC). Travis et al. proposed a fourth category of large cell neuroendocrine carcinoma, which is characterized by light microscopic neuroendocrine appearance, cells of large size, polygonal shape, low nuclear cytoplasmic ratio, coarse nuclear chromatin, with prominent nucleoli high mitotic rate and frequent necrosis; and neuroendocrine features by immunohistochemistry or electron microscopy. High grade neuroendocrine carcinoma (LCAC-NE) revealed aggressive clinical course. We report two cases of neuroendocrine tumors of the lung characterized by a trabecular pattern of large pleomorphic cells with frequent mitoses and wide necrosis. The frequent metastatic sites of atypical carcinoid were liver, bone and brain. One of our case is presented, at first, as an ovarian mass, which shows multifocal rosettes and revealed metastasis from lung. Both cases expressed neuroendocrine differentiation by light microscopy and immunohistochemistry. However clinical neuroendocrine symptom were not present.

Fresh-cut foods have been widely used in the school foodservice industry due to their convenience and saving effects of labor and working hours. This study evaluated the effectiveness of using fresh-cut foods in school foodservice with respect to cost efficiency, customer satisfaction, employee satisfaction, and productivity. First, in terms of cost efficiency, the cost of the fresh-cut food per meal price significantly increased by 2.6% via the new production plan. Meanwhile, the costs of labor and food wastes significantly decreased by 3.0% and 0.3%, respectively, after implementing the new plan. Second, customer satisfaction towards foodservice significantly increased, from 2.94 points prior to the new plan to 3.45 points. Third, foodservice productivity such as of the number of meals per full-time equivalent employee increased by 5.7 meals, from 143.0 meals to 148.7 meals after intervention. The productivity index of work hours for producing a meal also increased and was reflected by a work time reduction of 0.77 minutes, specifically from 4.25 minutes to 3.48 minutes. The labor cost per meal also decreased by 29.9 won, from 331.91 won to 301.97 won, but there was no significant difference. Through these results, we identified that using pre-process foods in school foodservice has positive effects on labor saving, customer satisfaction, and employee work satisfaction.

PURPOSE: The purpose of this study was to identify the change and difference and relationship of postpartum depression and physical image. METHOD: The subjects consisted of 86 postpartum women at one general hospital in Seoul. The data was collected from September to November 2001. The instrument used for this study were SRD (Self-Rating Depression Scale) and Norris' Body Image Scale to evaluate depression and body image. The collected data was analyzed with frequency, mean, t-test, paired t-test, ANOVA and Pearson's correlation coefficient. RESULT: The result of this study were as follows: 1.The mean score of D2 was significantly higher than D1(p=.003). There was no difference significantly B1 and B2(p=310). 2. There was significant correlation between the two, D1-D2(r=.381, p<.01), B1-B2(r=.364, p<.01), D1-B1(r=.579, p<.01), D2-B2(r= .567, p<.01). (D1: depression of postpartum 1-3days, D2: depression of postpartum 6-8weeks, B1: body image of postpartum 1-3days, B2: body image of postpartum 6-8weeks) CONCLUSION: There was very high postpartum depression in postpartum women, but body image was positive. Also, there was correlated to postpartum depression and body image. Thus it is necessary to implement nursing intervention focused on to decrease the postpartum depression and to enhance the body image of the postpartum women.

Venous thrombosis is uncommon in young individuals. Hypereosinophilia is a rare cause of thrombosis that usually involves the heart and small vessels like retinal vessels. We report a case of massive deep vein thrombosis that developed in a young patient with hypereosinophilia who was successfully treated with continuous local infusion of urokinase.
