The total 223 cases of tetralogy of Fallot is analysed angiographically, in which selective biplanecinecardioangiography with axial projection has been done at the Departement of Radiology, Seoul National University Hopital, in recent 2 year and 4 months, with specific refrence to the location of pulmonic stenosis,and associated cardiac anomalies. The summary of the analysis is as follow; 1. Left ventriculogram (long axialoblique view) was necessary to detect the ventricular septal defects including anterior marginal VSD, and washelpful to identify the coronary artery anatomy and presence of PDA and evaluate the size of left ventricle. 2.Right ventriculogram(elongated RAO view) was the best projection for the demonstration of pulmonic infundibulumand was essential to differenciate and localize the ventricular septal defects. 3.In the right ventriculogram(4chamber view), well demonstrated the right ventricular outflow tract, pulmonary valve, and pulmonaryarteries(main, right, left and peripheral), and also perimitted the detection of ASD in levophase. 4. The positionof ventricular septal defects was perimembranous in 199 cases(89.2%), subarterial in 15 cases(6.8%) andinfundibular (intracristal) in 9 cases(4%). Multiple ventricular septal defects (perimembranous& marginal ) werefound in 11 cases(4.5%). 5. In 35 cases(15.5%), pulmonary stenosis is found only in pulmonary infundibulum. Thecombination of its components was most commonly anterior wall and conus septum hypertrophy in 24 cases(68.6%) 6.Combined pulmonary stenosis was identified in 188 cases(84.3%). The most common combination was infundibular andpulmonary valvular stenosis in 56 cases(29.8%) 7. Associated cardiac anomalies were right aortic arch in 53 cases(23.8%), persistent left SVC in 17 cases (7.7%), ASD in 13 cases (5.9%), PDA in 9 cases(4.1%), aberrant subclavianartery in 5 cases(2.2%), IVC interruption with azygos continuation in 2 cases, single coronary artery in 2 cases,and anterior descending artery from right coronary artery in 1 case, etc. 8. Selective biplanecinecardioangiography with axial projection is essential to evaluate the size of left ventricle and to localizethe ventricular septal defects and pulmonary stenosis, and to detect associated cardiac anomalies in T.O.F. Sometimes aortography is necessary when anomaly of coronary arteries is suspected.

Adenosine deaminase(ADA) is an enzyme capable of catalysing the pathway from adenosine to inosine. Previous studies have shown that this enzyme may be useful in recognition of a tubeculous etiology of pleural, peritoneal, or meningeal effusions. ADA activity was studied in 42 patients with large amount of pericardial effusion. Patients were subdivided into the following four group : (A) 15 cases of tuberculous effusions : (B) 4 with pyogenic effusions : (C) 15 with idiopathic effusions : (D) 9 with malignant effusions. The results were as follows ; 1) The mean ADA activities assessed in pericardial effusions were 134.0+/-77.6U/L in group A : 93.8+/-43.8 in group B : 38.3+/-23.2 in group C : 27.3+/-20.8 in group D. Comparing the level achieved in group A with all others, the difference is significant at the P<0.001 level. 2) The mean ADA activities assessed in sera were 50.7+/-57.2 U/L in group A : 63.5+/-24.1 in group B : 25.9+/-12.0 in group C : 14.0+/-7.5 in group D. Comparing the level achieved in group A with all others, there is no significant difference. 3) Specificity(0.87) and sensitivity(0.93) of the test for the differential diagnosis of patients with tuberculous effusion from those with idiopathic effusion is high, when a value of more than 50 U/L is considered. In conclusion, the assessment of ADA in pericardial effusions is of great value in the diagnosis of tuberculous pericarditis.

The Saville's index of the lumbar spine and the Singh's index of the femoral neck is very simple method to measure degree of osteoporosis. Authors compared Singh's index and Savilles index with Dual Photon Absorptiometry(D.P.X.) and studied the reliability and clinical usefulness of two indices. We took the D.P.X. and simple L-spine lateral view in 103 patients in same time and also performed D.P.X. and both hips A-P view in 70 patients, then analyzed and compared each two indices with D.P.X. The Singh's index had less interpersonal difference and intrapersonal difference compared with Saville's spine index. There was some confidence of Singh's index and Saville's spine index compared with the D.P.X., but the relationship between Saville's spine index and D.P.X. was less promising than that of Singh's index. Authors suggest that the Saville's spine index has less clinical usefulness than Singh's index in measurement of osteoporosis.

Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.

Bony defect is one of the most common problems in craniomaxillofacial surgery. Although aurogenous bone graft is the best choice for the treatment of bone defect, it provides many problems such as donor site morbidity, irregular absorption, and limited amount of harvest. To overcome the shortcomings of autogenous bone graft many bone substitutes have been introduced. The ideal bone substitution is to have characteristics such as cheap, easy to obtain, rapid fusion to recipient bone, hard structure, long maintenance of shape and volume, low infection rate, and low exposure rate. Among those bone substitutes which have been widely used we chose lyophilized cartilage allograft because of low antigenecity, low resorption rate, easiness of carving and ling term preservation. From August 1993 to August 1997, 66 patients had been performed craniomaxillofacial reconstruction with lyophilized cartilage allograft. Orbital wall reconstruction and correction of enophthalmos were 24, correction of cleft lip and nose deformity were 19, temporal augmentations were 7, and others 16. Complications such as infection, exposure were not common. And partially removed cartilage was proved some calcification. Radiologic follow-up presented well positioned lyophilized cartilage allograft. Two radiologic works revealed haziness of bone density at the site of cartilage allograft. This suggests the ossification of lyophilized cartilage allograft. Together with liw infection rate, low exposure rate, and good framework for osteoconduction, lyophilized cartilage allograft are regarded as one of the good bone substitutes.
