A prospective study had been performed in infants with hydronephrosis due to ureteropelvic junction stenosis to determine adequate management plan. Forty infants (47 renal units) were selected for the study during the period from January 1995 to July 1997 in the Department of Pediatrics, Asan Medical Center. They were diagnosed prenatally or early postnatally (<3 months of age) on the basis of renal ultrasonography and techotium-99m-mercap- toacetyltriglycerine (MAG3) scan. The antero-poste- rior pelvic diameter (APPD) was measured from serial renal ultrasonography and relative renal function and clearance half time (T1/2) were calculated from serial MAG3 scan. Those who had accompanying other urogenital anomalies or vesicoureteral reflux were excluded in this study. Follow-up tests (ultrasonography and MAG3 scan) and surgical corrections, if necessary, were performed according to the predetermined algorithrn. The male to female ratio was 3: 1. Hydronephrosis was involved the left side in 24 renal units, the right side in 9 renal units, and the bilateral sides in 14 renal units. All the hydronephrotic renal units were divided into 2 groups; Group A (19 renal units) those had taken surgical correction, and group B (28 renal units) those revealed spontaneous improvement without surgical correction. The mean follow-up duration was 7.2+/-6.3 months in group A and 14.1+/-12.6 months in group B. The mean APPD in the first postnatal renal ultrasonography was 19.4+6.8 mm in group A and 10.0+/-3.0mm in group B and this was statistically significant (P<0.01). The rela- tive renal function of group A in the first MAG3 scan was under 35% in 7 renal units and over 35M in 12 renal units. In group B, the relative renal function was over 35% in the all 28 renal units. Tl/2 in the first MAG3 scan was longer than 20 minutes in the all 19 renal units in group A. In group B, Tl/2 was shorter than 10 minutes in 15 renal units, between 10 minutes and 20 minutes in 6 renal units, and longer than 20 rninutes in 7 renal units. The mean APPD of the 7 renal units in group B of which Tl/2 was longer than 20 minutes was 12.62.6mm and that of group A was 19.4+/-6.8mrn and this was statistically significant (P<0.01). In conclusion, the renal ultrasonography and MAG3 scan can be used effectively to determine the degree of the stenosis of the ureteropelvic junction in hydronephosis during infancy. When the babies are diagnosed with hydronephrosis due to ureteropelvic junction stenosis in the early infantile period, serial renal ultrasonography and MAG3 scan play an important role in the decision of the management.

The common errors in preoperative treatment plan for the orthognathic surgery can be occurred during cast impression, cast mounting procedure with face-bow transfer, surgical stent fabrication, and so on. One of the most common errors exists during mounting process of the model on the articulator. Accurate mounting of dental casts to articulator should be achieved by transferring the 3- dimensional spatial relationship of the maxillary arch to an articulator. A face-bow is used for transfer this relationship to articulator, usually by relating the face-bow to a plane of reference of maxillary cast. The purpose of this study is evaluation of the accuracy of face-bow transferring of maxillary model to the articulator. The maxillary casts of thirty patients for orthognathic surgery were mounted on articulator with an face-bow instrument. The relationship of occlusal plane angle to Frankfort horizontal plane relations were compared the cephalogram with the cast-mounted articulator. As a result of this study, the significant difference between the maxillary occlusal planes angle in the cephalogram and articulator were found . The results were followed,1. The mean occlusal plane angle in cast-mounted articulator was 13.5.(SD+/-5.4).2. The mean occlusal plane angle in cephalogram was 10.4.(SD+/-4.3).3. The mean difference of occlusal plane angle between cast-mounted articulator and cephalogram was 3.3.(SD+/-4.6).According to the result, we should suggest that the occlusal plane angle to Frankfort plane in cast-mounted articulator is more steeper than that of cephalogram.And then, maxillofacial surgeon should try to get a more predictable result by suggesting the proper correction method and mounting the cast accurately.

BACKGROUND: The coagulation and fibrinolytic activities increase in the setting of acute myocardial infarction (AMI) and has been shown to increase further after the administration of thrombolytic agents. The reocclusion rate was slightly higher in patients with recombinant tissue type plasminogen activator (rt-PA) than urokinase (UK). However, there are few studies on serial changes in coagulation and fibrinolytic activities during the thrombolytic therapy. METHODS: Twenty five AMI patients who visited Yongdong Severance Hospital from August 1996 to August 1997 were recruited. They were randomized two groups either double bolus UK or accelerated rt-PA. Plasma levels of fibrinogen, thrombin-antithrombin III complex (TAT), plasmin-alpha2 plasmin inhibitor complex (PIC), activities of protein C and protein S were checked before and 3, 12, 24hrs and 7days after the thrombolytic therapy. RESULTS: Plasma level of fibrinogen was decreased 3 and 12hrs after the initiation of thrombolytic therapy in both groups (p<0.05) however, the fibrinogen level in UK treated group (59.9+/-33.5 mg/dl) was decreased than rt-PA treated group (198.2+/-64.3 mg/dl) at 3hrs after thrombolytic therapy (p<0.05). Activities of protein C and protein S were increased at 3hrs after thrombolytic therapy in both groups and no difference was noticed between UK and rt-PA group. Concentrations of TAT and PIC were increased in both groups even before the thrombolytic therapy was initiated. The increment of TAT level was larger in rt-PA group (21.7+/-16.1, 8.9+/-5.4 ng/mL) compared with UK group (15.0+/-17.9, 4.6+/-1.9 ng/mL) at 3 and 12 hrs after thrombolytic therapy (p<0.05). PIC level was significantly increased at 3 and 12 hrs after the treatment in both groups and no difference was noted between UK and rt-PA group. CONCLUSION: Both coagulation and fibrinolytic activities, activated already before thrombolytic therapy, were further aug-mented after thrombolytic therapy in AMI patients. The increment of fibrinolytic activity showed no significant difference between UK and rt-PA treated group. However the coagulation activity in rt-PA treated group was increased more than UK treated group.
