Acetabular fractures assume great clinical importance because acetabular is weight bearing joint in the lower extremity. The undisplaced fractures of the acetabulum gave satisfactory results with closed method, but the treatment of displaced fractures have been controversial. A clinical analysis was performed on the 72 patients with displaced acetabular fractures, who had been treated at Soonchunhyang University Hospital from January 1980 to December 1989. The results obtained were as follows. 1. The prevalent age ranged from 21 to 50 years, which comprised 86.1% of all, and the ratio between male and female was 3:l. 2. The most common cause of injury was traffic accident, which comprised 76.4%. 3. According to Letournel's classification, simple fracture was 38 cases (52.8%), associated fracture was 34 cases (47.2%) and hip dislocation was associated in 28 cases (38.9%) and most common was posterior (20.8%). 4. Closed treatment was done in 47 cases and open treatment in 25 cases. 5. Results of open treatment group were better than closed treatment group in both clinical and roentgenographic study. 6. The complication were occured in 14 (29.8%) out of 47 cases of closed treatment group, and 10 (40.0%) out of 25 cases of open treatment group. 7. Not only choice of treatment but also determination of surgical approach require accurate assessment of the fracture pattern in this region of complex bony architecture by careful radilogic analysis.

Percutaneous extraction of residual biliary tract stones through T-tube tract was established as a successfuland generally accepted radiologic procedure in patients with post-operative retained stoens. Percutaneous removalof residual stones was performed in 43 patients at the Departement of Radiology, Seoul National UniversityHospital from November, 1982 to August, 1984. The results were as follows; 1. Location of residual stones areintrahepatic in 29 cases(67.4%) extrahepatic in 11 cases (25.6%) and combined in 3 cases. 2. Number of residualbiliary stones was single in 14 cases and 2 to 10 stones in 17 cases. 12 patients had more than 10 stones. 3.Success rate was 100% in extrahepatic stones ans 68.9% in intrahepatic stones. Overall success rate was 76.7% 4.There was no significant complication of this method.

The "flosting knee" is the term applied to the flail knee joint segment resulting from a fracture of the shaft of adiacent metanhysis of the ipsilateralfemur and tibia. The various methods of treatment of the "floating knee" were adapted by many authors according to degree of the comminution, degree of the soft tissue injury, general condition state of the fracture. Authors experienced the floating knee in 52 cases on 51 patients who were treated at Soon Chun Hyang University Hospital in the period of 4 years and 5 months from January 1985 to June 1989 and among them, 45 cases were treated by operative method and 7 cases by conservative methods at least one of the femur and tibia, The results were as follews;1. Floating Knee occured six times more in male and the peak age was third and fourth decades. 2. The most common cause of fractures was traffie aecident and there was difficulty in diagnosis of ligamentous disruption of the ipsilateral knee. 3. The common fracture site were middle one third and the most common fracture shape was comminuted in both femur and tibia. 4. A good or excellent functional result was aohieved in treated with open reduction and rigid fixation of both fracture and there were no significant difference in group of the internal fixation of both femur and tibia. 5. Intramedullary nailing on the femur and plate fixation on the tibia provided rigid fixation of fracture and the it made possible early joint motion exercise and ambulation and the average healing time of fracuture was much shortened. 6. The most common concomitant injury were soft tissue injury and delayed or nonuion and osteomyelitis were developed more frequently in the plate and screw fixation group of the open fracture.

There are many controversies concering primary treatment of fractures of the tibial shaft. Recently, flexible intramedullary nailing for the tibial shaft fracture has gained popularity, because of promotimg osteogenesis with early weight bearing and preventing ankylosis of the joints. Authors carried out retrospective study of the 142 tibial shaft fractures in 141 patients, and results were as analyzed. The results were as follow:l. Among 141 patients, 116 cases were male and 25 cases were female. The average age was 37 years and the most cause of injury was traffic accident. 2. The number of cases of closed and open fractures were 71 cases, respectively. The most common type of the fracture was comminuted and the level was middle third. 3. The number nails were inserted from two to five according to width of the medullary cavity and to gain of the stability after reduction at the fracture site. 4. Average bone union in X-ray was 17.8 weeks, 96 cases were united within 20 weeks and 43 cases were united after 21 weeks. 5. Complications were 3 cases of non-union and 17 cases of valgus deformity, within 12 degrees.

To investigate long term effects of CAPD on the left ventricular function in end-stage renal disease patients, M-mode echocardiographic studies and measurement o fsystolic time intervals were performed in 20 CAPD cases, 28 hemodialysis cases and 29 uremic controls. Compared to the uremic control grup, the patients on CAPD treatment revealed significant improvement of ventricular contractility and reduction of volume. On the other hand in hemodialysis group, even though there was improvement of ventricular contractility, volume control was not adequate. In the systolic time interval measurement, it is postulated that increase of PEP/LVET ratio in CAPD group probably results from reduction of volume(preload) rather than from deranged ventricular function.

Nitric oxide(NO) has recently been identified as a short-lived intracellular messenger in the central and peripheral nervous systems. Nitric oxide synthase(NOS) is a key enzyme for NO biosynthesis by formation of citrulline from L-arginine. This enzyme reaction requires reduced nicotine adenine dinucleotide phosphate(NADPH) as a co-factor and the electron transferring c-terminal sequence of NOS give rise to its NADPH-diaphorase activity. However, it has yet to prove that NO is a sensory neurotransmitter in olfactory nervous system. The purpose of this study was to localize histochemically the distribution of NADPH-diaphorase in the olfactory system of rats. In the olfactory mucosa, NADPH-diaphorase positive cells were demonstrated in the ciliary layers, Bowmann's glands and olfactory nerve bundles. In main olfactory bulb, a large number of NADPH-diaphorase positive cells were also demonstrated in nerve fibers of olfactory nerve layer, periglomerular cell, superficial short axon cells of external plexiform layer and deep short axon cells between granular and subependymal layers. Furthermore there were NADPH-diaphorase positive cells of plexiform and granular cell layers of the accessory olfactory bulb. Therefore, it is suggested that the presence of NADPH-diaphorase acitivity in nerve fibers of olfactory system may be involved in odor processing.
