PURPOSE: A retrospective review of the medical records of 168 patients who were evaluated for renal transplantation was undertaken to determine whether a voiding cystourethrography (VCUG) influenced the surgi cal care of the recipient. MATERIALS AND METHODS: Between June 1989 to May 1998, 168 patients received a transplantation at our center. These patients proceeded to transplantation, with all of them receiving a VCUG as part of their evaluation. We compared incidence of postoperative complications between normal VCUG group and abnormal group during follow up period (mean 31. 6 months). RESULTS: An urologic abnormality was identified by VCUG in 15 (8.9%) of 168 patients and all of them were vesicoureteral reflux (VUR). In 15 patients with VUR, grade of VUR were grade I in 2, grade II in 10, grade III in 2 and grade IV in 1. None of them with VUR required surgical intervention and had postoperative complications related to VUR. CONCLUSIONS: The VCUG is not essential for the preparation of potential recipients for renal transplantation and should be utilized selectively in individuals with a history of urologic disease or when urinary tract abnormalities are identified by physical examination or an abnormal urine analysis.

This study was undertaken to investigate the morphologic changes following flushing, preservation and reperfusion procedures in a canine lung allotransplantation model. Donor lungs were flushed with modified Euro-Collins (MEC) solution, low potassium dextran glucose (LPDG) solution or University of Wisconsin (UW) solution, then stored at 10oC for 20 hours. Light microscopic and electron microscopic features of the lungs were examined after flushing, preservation and 2 hours after reperfusion. After flushing light microscopy showed focal mild alveolar collapse and interstitial edema. After preservation the lung tissue showed multiple foci of alveolar collapse, consolidation, and alveolar epithelial cell damage. After reperfusion the lung tissue showed diffuse alveolar collapse, consolidation and many destroyed cellular debris in the alveolar lumina. After flushing electron microscopy showed focal alveolar collapse and mild swelling of type I epithelial cells. After preservation both type I epithelial cells and endothelial cells were swollen and destroyed focally. Some type I epithelial cells were detached from the basal lamina. The endothelial cells showed luminal protrusion of tactile-like structure and vacuoles of the cytoplasm. After reperfusion the lung tissue showed fibrin material in the alveoli, prominent type I epithelial cell swelling with fragmented cytoplasmic debris and marked endothelial cell swelling with vacuoles or tactile-like projections. The alveolar macrophages showed active phagocytosis. After preservation scanning electron microscopic examination of the pulmonary arteries showed multiple patchy areas of swelling or conglomerated lesions in the inner surface of the pulmonary arteries. In conclusion, the ultrastructural changes associated with flushing were mild in severity, the donor lungs were injured during the preservation, and further damage occurred during the reperfusion.

Granular cell tumor is one of the rare tumorous condition. At present there are estimated 600 reported examples of the tumor in the medical literature. Malignant granular cell tumor is a well established but extremely rare entity that is found in appr- oximately 2 % of all granular cell tumor. Diagnosis should be restricted to neoplasms that are similar in their histological appearance to benign granular cell tumors but can be seperated on the basis of cellular pleomorphism, mitotic activity, and, most importantly, their capacity to produce metastases. The authors had experienced that a 55 years old male patient had two large malignant granular cell tumors at the left thigh and left inguinal area with metastatic lesion.

9.Gray-Scale Stimulated Acoustic Emission: Differential Diagnosis between Hepatocellular Carcinoma and Metastastic Adenocarcinoma.
Journal of the Korean Radiological Society 2001;44(1):63-68
PURPOSE: To assess the value of gray-scale stimulated acoustic emission in differential diagnosis between hepatocellular carcinoma and metastatic adenocarcinoma. MATERIALS AND METHODS: Twenty-four cases of epatocellular carcinoma (HCC) in 23 patients and 26 cases of metastatic adenocarcinoma in 14 patients were prospectively examined using the pulse-inversion harmonic technique after intravenous SH U 508A administration. Gray-scale stimulated acoustic emission (SAE) was measured 5 mins after bolus injection of a contrast agent (4g, 400 mg/ml). The presence or absence of SAE signals at internal and marginal areas of the tumor and the appearance (smooth or irregular) of its border were compared. In addition, the SAE index [SAE (parenchyma) - SAE (tumor)/ SAE (parenchyma)] was histographically determined using a computerized program (PiView TM ; Mediface, Seoul, Korea). The statistics were analysed using student'st test. RESULT: Of the 24 HCC cases, 20 (83%) showed internal SAE signals, while 23 (96%) marginal signals were emitted. Of the 26 cases of metastatic adenocarcinoma, one (4%) showed internal SAE signals, while in five (19%), these signals were marginal. The tumoral border was irregular in 19 HCC lesions (79%) and smooth in 23 metastatic lesions (88%). For HCC and metastatic tumors, the mean SAE index was 0.38 +/-0.15 and 0.60 +/- 0.08, respectively (p < 0.001). CONCLUSION: Gray-scale stimulated acoustic emission can be a useful tool in differential diagnosis between heatocellular carcinoma and metastatic adenocarcinoma.

10.A Case of Hypoglycemia following Cesarean Section .
Young Hwa MOON ; Chang Jae KWON
Korean Journal of Anesthesiology 1978;11(3):279-281
Little has been reported concerning post-operative hypoglycemia in previously asymptomatic individuals. Post-operative hypoglycemic coma is one of the most perplexing problems and must be differentiated from other conditions accompaning coma. We experienced a case of hypoglycemia following emergency cesarean section in primigravida with cephalopelvic disproportion on the fourth post operative day. The comatous state appeared abruptly and developed repeatedly. The causes of post-hypoglycemic coma are discussed and the prolonged starvation before and after operation was suspected to be the cause of coma.
