We analyze ninty-seven cases of Colles fractures treated with closed reduction and sugar tong splint immobilization and followed for more than 1 year at Seoul National University from January 1981 to Decmber 1985. The results of this study were as follows; l. All of 97 cases were closed fractures and the incidence was high in females who aged over 6th decades. The main cause of this injury was slipping down accident comprising of 68.0%. 2. 63 cases (64.9%) were simple extra-articular fractures, and 34 cases (35.1%) were comminuted intra-articular fractures. 3. In a group of simple extra-articular fracture the functional end result was satisfactory in 88.9%, so closed reduction and sugar tong splint were thought to be a good procedure in this group. 4. In a group of comminuted intra-articular fracture the functional end result was satisfactory in 58.9% only. In the cases which show unacceptable loss of position during first two weeks of routine sugar tong splint immobilization we feel another technique is indicated, such as.pin and plaster immobilization or percutaneous pinning. 5. The main cause of unsatisfactory result was malunion, which was produced by loss of reduction position.

OBJECTIVES: the aim of this study was to evaluate plasmin system in placenta fiom women with normal and preeclamptic pregnancy. METHODS: The levels of urokinase-type plasminogen activator(uPA), tissue-type plasrninogen activator(tPA), uPA receptor(uPAR) and plasminogen activatar inhibitor-1(PAI-1) mRNAs were measured by Northern blotting in placenta hom sixteen women with normal (n""8) and preeclamptic (n""8) pregnancy. The levels of tPA protein and PAI-1 protein were also measured by Westerrn blotting. RESULTS: Densitometric measurements revealed no difference in the levels of uPA mRNA, uPAR mRNA, tPA protein and PAI-1 protein in placentas fiom normal and preeclamptic pregnancies. There was, however, a significant decrease in the level of 3.2 kb PAI-I mRNA in placentas from preeclamptic women compared to normal pregnant women. CONCLUSION: To the contrary of our expectation, 3.2 kb PAI-1 mRNA level was significantly lower in placenta from women with preeclampsia compared to normal pregnancy. This seems to reflect differential accumulation of PAI-1 mRNAs due to environmental intluences or decreased differentiation potential of villous trophoblasts to invasive trophoblasts in placenta from preeclamptic women compared to normal pregnant women. The mechanism that regulates plasmin system in human placenta needs further investigations.

PURPOSE: We evaluated the importance of redistribution and 24 hour reinjection images in Tl-201 SPECT assessment of myocardial viability after acute myocardial infarction (AMI). MATERIALS AND METHODS: We performed dipyridamole stress-4 hour redistribution-24 hour reinjection Tl-201 SPECT in 43 patients with recent AMI (4-16 days). The myocardium was divided into 16 segments and perfusion grade was measured visually with 4 point score from 0 to 3 (absent uptake to normal uptake). A perfusion defect with stress score 2 was considered moderate. A defect was considered severe if the stress score was 0 or l (absent uptake or severe perfusion decrease). Moderate defect on stress image were considered viable and segments with severe defect were considered viable if they showed improvement of 1 score or more on redistribution or reinjection images. We compared the results of viability assess-ment in stress-redistribution and stress-reinjection images. RESULTS: On visual analysis, 344 of 688 segments (50%) had abnormal perfusion. Fifty two (15%) had moderate perfusion defects and 292 (85%) had severe perfusion defects on stress image. Of 292 severe stress defects, 53 were irreversible on redistribution and reversible on reinjection images, and 15 were reversible on redistribution and irreversible on reinjection images. Two hundred twenty four of 292 segments (76.7%) showed concordant results on stress-redistribution and stress-reinjection images. Therefore 24 hour reinjection image changed viability status from necrotic to viable in 53 segments of 292 severe stress defect (18%). However, myocardial viability was underestimated in only 5% (15/292) of severe defects by 24 hour reinjection. CONCLUSION: The 24 hour reinjection imaging is useful in the assessment of rnyocardial viability. It is more sensitive than 4 hour redistribution imaging. However, both redistribution and reinjection images are needed since they complement each other.

We introduced a method of splitting the lamellar scleral flap(LSF) after trabeculectomy with 5-fluorouracil(5-FU) to evaluate the postoperative wound strength which may reveal directly th6 antiproliferative effect of 5-FU. An 8-0 nylon sture was placed under the LSF at the time of trabeculectomy and both ends of the suture were drawn out from the conjunctiva. The wound strength was evaluated by pulling out the spitting suture at the end of second week after operation. Seventeen eyes of 16 patients underwent a primary trabeculectomy and placement of a splitting suture. 5-FU was injected subconjunctivally, 5 mg every other day in the eyes during postoperative two weeks. Five(50%) of ten eyes of 5-FU group resulted in LSF splitting(p=0.0407, Fisher's exact test). This result may signify that the LSF splitting suture technique will be a helpful means to investigate the effect of post-trabeculectomy wound healing modulators in the early period postoperatively.
