Recently, the radionuclide angiocardiographic study had been enhanced by rapid development of gamma scintillation camera and computer system, and utilized as noninvasive diagnostic measurement of heart disease. We obtained the following results by the radionuclide angiocardiography with human serum albumin tagged with 99m-Technetium from two groups. One of them was congenital heart disease group(n=50, ventricular septal defect 20, atrial septal defect 6, pulmonary stenosis 2, tetralogy of Fallot 10, truncus arteriousus 1, transposition of great artery 1, patent ductus arteriosus 10) operated from Oct. 1984 to Jun. 1985, and the other was the normal human group(n=10) as control. 1) In the cases of left to right shunt, Qp/Qs values were calculated by th gamma variet fit curve. The preoperative values ranged from 1.441-3.00, the postoperative values were normal among all the patients except one(atrial septal defect, postop. Qp/Qs 2.335). 2) In the cases of right to left shunt, Qp/Qs values showed no apparent change between pre. andpostoperative period, possibly due to still remained collateral circulation and hardly obtained lower value(less than QP/QS 1.0) by computer system, But the double peak curve was noticed in the left ventricular time activity curve, which indicate right to left shunt, disappeared after the surgery, suggesting shunt closed. 3) The ejection fraction of left ventricle was obtained from the congential cardiac patients, ranged 0.38-0.65 before the surgery and 0.41-0.67 after the surgery. 4) The circulation time calculated from the first-pass radionuclide angiocardiography, ranged normal in the most congenital cardiac patients, but prolonged in the severe pulmonary hypertension.

Essential hypertension is an important public health problem in Korea-being common, asymptomatic, easily treatable, and often leading to lethal complication in left untreated. The number of patients with hypertension has been significantly increased, and this factor may be an importnat one responsible for the increase in cardivascular mortality during past 20 years in Korea. As the drug therapy for hypertension needs longer period, it is very important to evaluate the efficacy and the adverse effects. Thirty patients(17 men and 13 womon) with essential hypertension were evaluated in this study. All patients had received oral Isradipine 1.25~2.5mg b.i.d. for 8 weeks. 1) The systolic and diastolic pressure were decreased significantly(166.8+/-9.0mmHg vs 147.3+/-12.0mmHg, p<0.001 and 100.3+/-4.0mmHg vs 90.3+/-6.1mmHg, p<0.001, respectively) 2) Heart rate, body weight, laboratory tests, chest X-ray, ECG studies were not changed significantly. 3) The systolic pressure was lowered by 20mmHg or more in 17 cases(56.7% of total), and the diastolic pressure was lowered by 10mmHg or more in 20 cases(66.7% of total) at 8 weeks after Isradipine administration. 4) The adverse effects of Isradipine were edema in 3(10%), constipation in 2(6.7%), headache in 2(6.7%), and insomnia, dizziness and dry mouth in 1 patient respectively, and none of them discontinued Isradipine administration due to adverse effects. In many patients with essential hypertension there is an effective response to Isradipine, even though there may be some mild adverse effects.

This study was performed to estimate the correlation between the histopathological grade and the clinical stage, which are known as important prognostic factors, and EGFR expression status in 57 cases of transitional cell carcinoma of the urinary bladder. There was a significant correlation between the histopathological grade and clinical stage of transitional cell carcinoma of the urinary bladder and between expression grades of EGFR and histopathological grades, or clinical stages of transitional cell carcinoma of the urinary bladder. Therefore, the presence of a high intensity of EGFR staining in the transitional cell carcinoma of the urinary bladder was associated with poor differentiation and invasion. On the basis of the above results, it was suggested that the degree of EGFR expression is one of the objective and reliable prognostic factors in transitional cell carcinoma of the urinary bladder.

PURPOSE: Choledochal cyst is a rare malformation of the pancreatobiliary ductal system, manifested by dilatation of biliary tree with or without anomalous insertion of the common bile duct into pancreatic duct. The purpose of this study is to review the incidence of anomalous pancreatobiliary union(PBU) and the shape of common bile duct based on the angle of pancreatic duct and common bile duct union. MATERIALS AND METHODS: We analyzed cholangiopancreatographic findings of 21 patients with choledochal cyst, emphasizing PBU. The PBU was classified into acute-angled PBU, right-angled PBU, normal PBU, and unknown PBU on the basis of common bile duct insertion to pancreatic duct. The shape of common bile duct dilatation was evaluated with regard to angle of PBU. RESULTS: Fourteen of 21 patients had anomalous PBU with slender or ectatic form of common channels. Three patients had normal opening of common bile duct and pancreatic duct, and in remaining 4 patients the PBU was not visualized. Among 14 patients with PBU, 5 patients had right-angled PBU and 9 patients had acute-angled PBU. Cystic form of common bile duct dilatation was seen in 13 patients and cylindrical form was in 8 patients. Cystic dilatation of common bile duct was seen in 4 patients out of 5 right-angled PBU. CONCLUSION: Patients with choledochal cyst had high incidence of anomalous PBU with common channel (67%). The shape of common bile duct dilatation was cystic in 62% of patients, and the right-angled PBU was prone to be cystic dilatation (80%).

We anlized CT of 29 cases of various orbital disease in pediatric age group. Diagnoses were confirmed byeither operation or direct ophthalmoscopy. The patients were examined during the period of last 3 years. Theresults were as follows: 1. Of 29 cases, 21 were male and 8 were female, and the age ranged from 20 days to 15years. 2. Intraorbital tumors were 13 cases consisting of 7 retinoblastoma, 3 pseudotumor, and 1 each ofcongenital teratoma, cavernous lymphanngioma, and optic glioma, Of remaining 16 cases, 6 had orbital fracture, 5persistent hyperplastic primary viterous(PHPV), 3 vitreous opacity, and 2 primary glaucoma. 3. The CT findings ofthe retinoblastoma were a lobulated or oval soft tissue mass denisty (40-60HU) extending into the vitreous wtihoutsignificant enhancement on postcontrast scan. Of 7 cases, 4 had calcifications within the tumors. The extraglobalextension of the tumor was shown in 2 patients demonstrating markedly thickened sclera with enhancement anddilated optic nerve. 4. There were 5 patients with PHPV having a history of white pupil since birth, and all wereaffected unilateraly. Four patients had vitreous opacity and 3 of those showed either linear or branchingtree-like densities within the vitreous on the postcontrast scan. Another one had a lobulated increased densityprotruding into the vitreous which was difficult to differenciate from the similar finding of retinoblastoma.Remaining one case demonstrated a deformed and decreased density in the lesional lens without chaneg in thedensity of the vitreous. This was confirmed to be caused by persistence of the embryonic hyaloid artery attachedto the posterior capsule of the lens. 5. There were 3 patients with vitreous opacity and 2 of them were due toretinal detachment and 1 was caused by retrolental fibroplasia. The CT findings of retinal detachement werehomogenous or heterogenous opacities in the vitreous. In a case of retrolental fibroplasia, irregular, band-likedensity was seen along the posterior wall of the globe bilaterally. 6. Two cases of primary glaucoma showed largeglobe with a widened anterior chamber. 7. Among 6 cases of orbital fractures, 5 were blow-out fracture. Theblow-out fractures showed fractures of the medial orbital wall or orbital floor with herniated intraorbitalcontents into the neighboring ethmoid or maxillary sinus.

We have detailed our experiences on 6 cases of neonatal lethal short- limbed dwarfism and reviewed thearticles. They include, achondrogenesis, thanatophoric dysplasia, asphsiating thoracic dysplasia, osteogenesisimperfecta congenita, and hypophosphatasia lethalis. Five babies were born alive but died soon after birth and onewas a stillbirth. The main cause of failure to thrive was respiratory insufficiency. Each case was having quitecharacteristic radiologic findings, even if the genearl appearances were similar to the achondroplasts clinically.Precise diagnosis is very important for genetic counselling of the parents and alarm to them the possibility ofbone dysplasias to the next offsprings. For this purpose, the radiologists play major role for the correctdiagnosis. We stress that when the baby is born with short-limbed dwarfism, whole body radiogram should be takenincluding lateral view and postmortem radiogram is also very precious.
