We retrospectively analyzed 22 patients pelvic CT, in whom the acetabular fracture were suspected in plain film. And compared and analyzed the computed tomogram findings and plain radiographic findings. The results were as follows. CT enables better evaluation of shape, extent, and degree of separation of fragment. CT was helpful in detecting the combined fracture and soft tissue injuries. CT showed intraarticular loose bodies, which were invisible on plain film. In patients with pelvic trauma, no necessary changing position during CT examination. CT was useful demonstrates the remnant of intraarticular osseous fragment and adequacy of reduction after surgery.

PURPOSE: To evaluate the diagnostic accuracy of T-tube cholangiography(TTC), selective cholangiography (SC) and noncontrast CT(NCT) in the evaluation of intrahepatic stone disease. MATERIALS AND METHODS: We retrospectively analyzed the radiological findings of these methods in thirty patients with intrahepatic stones proved by percutaneous removal. Findings of each procedure were reviewed and correlated with findings of stone removal procedure. RESULTS: Detection of stones was possible in 87. 0% for TTC, 90. 0% for SC, 96. 7% for NCT(p > 0.05). Selective cholangiography was as good as or superior to 1-I'C in determining the presence and extent of the stones in all patients(p < 0. 01). NCT was better than SC in 9;as good as SC in 18;inferior to SC in 3 patients in determining the extent and location of the stones(p > 0.05). Of 12 patients who had additional findings such as biliary cirrhosis or accompanied cholangiocarcinomas, only NCT could detect the lesions in 11 patients. CONCLUSION: Although there was no statistically significant difference between NCT and SC, one procedure sometimes gave valuable informations for interventional procedure which the other could not. Thus we conclude that both procedures are complementary studies and should be done in all patients who are subjected to biliary intervention.

This study observed the changes of the glycogen content in extensor digitorum and soleus by electrical stimulation on the sciatic nerve with various frequencies, and the result were compared with those of treadmill running exercise. The results are summarized as follows ; The glycogen content of extensor digitorum longus was greater than that of the soleus in the normal group, and the reducing amount of glycogen content of extensor digitorum longus was greater than that of the soleus by overnight fasting. As the frepuency of electrical stimulation was increased by 2, 5 and 10Hz., the glycogen content of the extensor digitorum longus was slightly reduced or changed minimally. As the loading period of clectrical stimulation was increased to 30 and 90minutes, the glycogen content of extensor digitorum longus was much reduced from early stage, and that of the soleus was the same tendency as the frepuency increased. The glycogen content of the extensor digitorum longus was proportionally reduced by treadmill running excercise, and that of the soleus was much reduced from the early stage. In summary, based on the experimental evidence of this investigation, it showed the different physio-chemical responses of th fast and slow twitch muscle fibers by electrical stimulation, and also not the equal responses of muscle fibers by electrical stimulation and treadmill running exercise.

The aim of this study was to analyze the process of restoration of muscle power following arthroscopic primary repair of ACL with manual test and Cybex test for one year postoperatively. Arthroscopic primary repair of the ACL was performed in 24 fresh tear. Postoperatively a limited motion brace was applied. Full weight bearing was allowed at 10 weeks postoperatively. In all cases mid-thigh circumference at 7.5 cm proximal to the upper pole of patella was measured. Manual muscle power test and Cybex test were also performed and the differences between the normal and the affected legs were recorded. The manual test and measurement of mid-thigh circumference were performed at 6 weeks, 12 weeks, 6 months and 1 year postoperatively. All cases showed 'normal' muscle power at 6 weeks after surgery in manual test. The mean difference of mid-thigh circumference was 4.5 cm(range 2.0-6.0 cm) at 6 weeks, 3.6 cm(range 1.0-6.5 cm) at 12 weeks, 2.9 cm(range 1.8-4.8 cm) at 6 months and 0.9 cm(0.5-2.5 cm) at 1 year after surgery. The peak torque deficit measured by Cybex test showed 50-82%(average 65.8%) in extensor and 24-96 %(average 60.6 %) in flexor at 12 weeks, 21-60 %(average 41.4 %) in extensor and 2-50 %(average 32.4 %) in flexor at 6 months, 1-23 %(average 13.1 %) in extensor and 1-19 %(average 11.4 %) in flexor at 1 year after surgery. From these results it would be suggested that the peak torque of muscles was not normal by Cybex test although the muscle power was restored clinically by 1 year following surgery.

Percutaneous removal of residual biliary stone was performed through T-tube tract in 10 patients at theDepartement of Radiology, College of Medicine, Seoul National University from November, 1982 to May, 1983. Forpercutaneous biliary stone removal is easy to perform, high in success rate, applicable in outpatient andnegligible in complication, active clinical application of the percutaneous removal is recommended as the primarymethod for residual stone instread of surgical re-operation.

Malignant gastric lymphoma is an uncommon but important lesion with a more favorable prognosis than that ofgastric carcinoma. A total of 16 cases of gastric malignant lymphoma examined during a period from Jan. 1980 toSept. 1983 at Seoul National University Hospital were subjected to the radiological and pathologic correlations.In all cases, the diagnosis was established by histopathology of the resected specimens (9 cases) or endoscopicbiopsy specimesn ( 7 cases). Based on the comparative study of upper G-I series and macroscopic findings of thesurgically resected specimen, the authors investigated the reliable radiographic findings which can be valuable indifferentiation of gastric lymphoma from other gastric lesions, especailly carcinoma, and suggested the followingdiagnostic criteria for the malignant lymphoma of the stomach. 1. Discrete multiple polypoid lesions with orwithout central umbilication. 2. Geographic ulcer, deviated from center of the mass. 3. Irregular thickness ofelevated rim of the mass. 4. Diffuse giant gastric rugae. 5. Giant gastric rugae, mixed with other lesion.

While effectiveness of ultrasound in diagnosis of stone in gallbladder and common bile duct has been wellestablished, role of ultrasound in detection of intrahepatic bile duct stone has rarely been described. However,in ultrasonographic diagnosis of common bile duct and gall bladder stone, evaluation of intrahepatic bile duct isessential to decrease the incidence of residual stone because about 5-8% of common bile duct and/or gall bladderstone also have stone in intrahepatic bile duct. We studied 27 cases of intrahepatic bile duct stone diagnosedwith ultrasound for recent 14 months from Sep. 1983 to Nov.1984 at Department of Radiology, Seoul NationalUniversity, and analysed ultrasonographic findings of the stones. The results were as follows: 1. In 27 cases outof total 35 cases(77.1%), intrahepatic duct stones were confirmed by operation, postoperative T-tubecholangiography, ERCP. PTC, and CT; in 4 cases(11.4%), there were no stone in hepatic duct; and in 4 cases (11.4%)intrahepatic ducts were not completely evaluated because of incomplete studies. 2. 17 cases of 27cases with provenintrahepatic duct stones had also common bie duct and/or gall bladder stones(63%). 3. Ultrasound showed echogenicmaterial (from due to mass) in 27 cases(100%), posterior shadowing in 26 cases(96%), and ductal dilatation in 23cases(85%). 4.Intrahepatic stones tend to be apeared as mass-like echogenecity, with the increase in size, numberand degree of agregation of stones.
