Sick neonates often require periodic small volume transfusion (10mg/kg) to replace blood draw for laboratory monitoring during their hospital stay. The effect of packed red cel transfudion on the hematocrit, potassium, ionized calcium, acid base status, glucose and indirect bilirubin was investigated in 25 transfusions. Analysis of transfused blood by the age of the red cells, older red cells (more than 5 days old, 13+/-7 days) showed increased potassium (27.2+/-14.1mEq/L vs 11.3+/-4.9mEq/L), decreased bicarbonate (14.4+/-2.6mEq/L) and glucose (130+/-28mg/dl vs 203+/-93mg/dl) compared with newer red cells (less than 5 days)(p<0.05). No significant changes occured in hematocrit and pH. Inspite of these results, the transfusion of the older red cells did not affect the older red cells did not affect the serum potassium, ionized calcium, pH, bicarbonate, glucose and indirect bilirubin level in neonates. The hematocrit of infants increated significantly after transfusion from 29.6%+/-4.3% to 38.3%+/-6.1%(mean+/-SD)(P<0.05). Transfusion of older red cells seemed to be as equally effective as newer ones. The valus of hematocrit obtained immediately after transfusion does not show any differences compared to those obtained 30 min, 1, 2, 4, 6 and 24 hours after transfusion. The result in the study indicate that there was no adverse effect after transfusion with packed red cell more than 5 days old and no significant difference in hematocrit observed between 0 to 24 hours following transfusion. Therfore old red cell more than 5 days can be used safely for sick neonatal transfusion and the stored donor blood can be optimzed for repeated blood transfusion.

BACKGROUND AND OBJECTIVES: It has been reported that various inflammatory and immune reactions are involved in the development and progression of atherosclerosis. We tried to investigate whether the TNF receptor superfamilies are involved in the development and progression of atherosclerosis. MATERIALS AND METHOD: Thirteen carotid atheroma specimens(frozen sections : 10 cases, paraffin section : 5 cases) were obtained from the patients who underwent carotid endarterectomy at Samsung Medical Center and one normal aortic tissue was obtained from a transplantation donor in brain death. In the carotid endarterectomy specimens and a normal aortic tissue , the expressions of R110(TR1), 139(TR2) and DR3(TR3), members of the TNF receptor superfamilies were evaluated by immunohistochemical staining with monoclonal antibodies. Simultaneously, we evaluated the expressions of foam cells, smooth muscle cells, T-lymphocytes and B-lymphocytes. RESULTS: Immunohistochemical analysis identified a strong expressions of foam cells and smooth muscle cells in all atheroma. But, the expression of T-lymphocytes was minimal and that of B-lymphocytes was rare. The expression of DR3(TR3) was seen in all atheroma as strongly positive. The expression of 139(TR2) was observed well in frozen sections, but not in paraffin sections. Whereas, that of R110(TR1) was observed in paraffin sections as weakly positive, but not in frozen section. The areas where the TNF receptor superfamilies were expressed correlated to the area of foam cell presence. The expression of DR3 also correlated with expression of smooth muscle cells. In normal aortic tissue, the expression of inflammatory cells or TNF receptor superfamilies was not observed except smooth muscle cells which were observed in normal artery. CONCLUSION: Foam cells and smooth muscle cells were abundantly present in atheroma. The TNF receptor superfamilies are expressed in the atheroma and the region of expression was coincident with the presence of foam cells.

We reviewed the medical records of 23 boys with surgically and pathologically proved monorchism. A striking laterality to the left side was identified. In 75 per cent of patients wolffian structures were present. These findings strongly suggest that in most instances of monorchism a testis had been present and had undergone subsequent in utero degeneration. Despite of various diagnostic technique for searching testes, we believe that surgical exploration continues to be the most reliable and more direct approach to the diagnosis and treatment of monorchism.

Liver is generally known as an organ which is most commonly involved by the metastic tumors. According to the tendency of using fine needle aspiration in the diagnosis of hepatic tumors, the differentital diagnosis between hepatocellular carcinoma and metastatic carcinoma frequently has been a main issue in the poorly differentitated cases, especially to the pathologists of Korea, an endemic area of hepatocellular carcinoma. Until now the problem has been usually solved by the comparison of cytologic characteristics of their tumor cells but not by background cytologic features which rarely have been studied. We observed the background cytologic features helpful for the differential diagnosis through the analysis of 20 cases who had confirmed primary cancer and were diagnosed as metastatic carcinomas in the liver by fine needle aspiration cytology. Twenty cases included 9 adenocarcinomas, 7 spuamous cell carcinomas, 1 small cell carcinoma, 1 carcinoid, 1 adenoid cystic carcinoma, and 1 renal cell cacinoma. Analysis of background cytologic features revealed that 77% of adenocacinoma cases showed benign mesenchymal components and hepatocytes and spuamous cell carcinoma cases disclosed benign mesenchymal tissue (71%) and necrosis (57%). Remaining cases showed variable combinations of benign mesenchymal component, necrosis, hepatocytes, and bile duct epithelial cells. No case revealed atypical hepatocytic naked nuclei, a useful cytologic finding of hepatocellular carcinoma. In summary, the background cytologic features more commonly observed in metastatic carcinomas than in the hepatocellular carcinoma were benign mesenchymal components, hepatocytes, necrosis, and bile duct epithelium. The endothelial cells and hepatocytic naked nuclei, two relatively specific findings of hepatocellular carcinoma were not observed except for renal cell carcinoma. Above background cytologic features are thought to be helpful for the differential diagnosis between the hepatocellular carcinoma and various metastatic carcinomas in the poorly differentiated cases.

We report a rare case of primary glomerular disease with both features of IgA nephropathy and membranous glomerulonephritis in a 27 year-old woman with nephrotic syndrome. Histologically, glomeruli showed slight mesangial expansion, proliferation of mesangial cells, and short subepithelial spikes on capillary wall. Direct immunofluorescence demonstrated granular IgG and C3 deposits along the capillary walls, and IgA with C3 deposits in mesangium. Granular subepithelial and rnesangial deposits were observed by electron microscopy. The patient showed complete remission after 6 months therapy with steroid and ACE inhibitor.

7.Refractive Effects of Excimer Laser Radial Keratotomy and Central Photorefractive Keratectomy using Excimer Laser for Correction of Myopia.
Journal of the Korean Ophthalmological Society 1995;36(11):1876-1884
This study was performed to compare the refractive effect and visual outcome of Excimer laser radial keratotomy(RK) with those of central photorefractive keratectomy(PRK) for myopia correction. The myopic eyes were subdivided into mild(-2.75D), moderate(-3.00 ~ -5.75D) and severe(>-6.00) myopia. In 54 eyes treated with RK 3 eyes(5.6%) were mild, 26 eyes(48.1%) were moderate and 25 eyes (46.3%) were severe myopic eyes. In 518 eyes treated with central PRK 10 eyes(1.9%) were mild, 214(41.3%) were moderate and 294(56.8%) were severe myopic eyes. Mean reduction of refractive power measured with skiascope following RK and central PRK in mild, moderate and severe myopia were 1.42 +/- 0.85D and 3.19 +/- 0.84D, 2.07 +/- 1.75D and 4.66 +/- 1.90D, and 2.54 +/- 2.45D and 7.54 +/- 2.81D, respectively. Mean reduction of keratometric diopter following RK and central PRK in mild, moderate and severe myopia were 2.00 +/- 1.05D and 3.66 +/- 1.03D, 1.90 +/- 1.05D and 4.83 +/- 1.99, and 1.52 +/- 2.54D and 5.58 +/- 3.46D, repectively. Uncorrected visual acuity following RK and central PRK in mild. moderate and severe myopia were 0.73 +/- 0.19 and 0.91 +/- 0.26, 0.43 +/- 0.30 +/- and 0.79 +/- 0.24, and 0.20 +/- 0.13 and 0.66 +/- 0.28, respectively. In conclusion, refractive effect and visual outcome of central photorefractive keratectomy was better than the those of radial keratotomy for correction of myopia; especially high myopic eyes.

Adenoid cystic carcinoma of the lung is histologically and ultrastructurally identical to the salivary gland tumor of the same name and is characterized by infiltrative growth, local recurrence, and usually a prolonged clinical course. We have recently experienced two cases of adenoid cystic carcinoma arising in the lung. Case 1 was a 59 year-old male who presented with cough, fever, and chill of 1.5 months' duration, and case 2 was a 61 year-old male who was incidentally found to have a 3 to 4 cm sized lobulated mass in the right upper lobe. After being worked up, both patients underwent right pneumonectomy. In case 1, a 3x2 cm sized tumor was located in the lower bronchus, partly elevating toward the lumen and partly infiltrating into regional lymph nodes and lung parenchyma showing grayish-white and solid cut surface. Case 2 was a 3.5x3.5 cm sized upper bronchial tumor resembling the former in appearance. Histologically, the tumors were composed of small round hyperchromatic cells, forming solid, cribriform, acinar, or tubular structures. Luminal spaces in tumor cell nests contained PAS-positive mucinous or hyaline material. Among the tumor cells, scattered islands of normal submucosal gland were noticed.

OBJECTIVES: The aim of this study was to investigate the association of social support and quality of life of stroke patients. METHODS: Stroke patients were interviewed by a direct contact survey among 160 person. A structured questionnaire was configured about demographic features, social support and health related quality of life (SF12). Data were collected from July to August 2009. RESULTS: Among social support, satisfaction of dependable when you need help is the highest score (5.3) and console you when you are very upset is the lowest (4.0). Vitality among health related quality of life (HRQOL) is the higest score (55.9) and general health score is the the lowest (17.4). Physical component score (PCS) is lower than mental component. The results of multiple regression analysis about the factors affecting the PCS and MCS score, disability grade and feel better variable gave effect HRQOL. CONCLUSIONS: For improvement of HRQOL, among stroke patients, community social support, specially, when patients feeling generally down-in-the dumps, the rely on to help feel better was needed.
