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.

The management of supracondylar fractures of the femur remains controversial. Most studies over the past twenty years have attempted to compare the results of non-surgical with those of surgical methods. Until a few years ago, conservative treatment was considered superior to internal fixation of supracondylar fractures of the femur. However, the development of new fixation devices and techniques have, according to several investigations, improved the results of the treatment of these fractures. The following clinical results were shown by analysis of 96 cases of supracondylar fractures of the femur treated in the Department of Orthopedic Surgery, Yonsei University, College of Medicine during the past 10 years from Jan. 1971 to Dec. 1980. 1. The prevalent age distribution was between 21 and 50 years of age (79.1%), and the ratio between males and females was 3.4:1. The most common cause of injury was car accidents (51.0%). 2. A classification of supracondylar fractures was unicondylar, simple supracondylar and intercondylar. Intercondylar which was subdivided into Type I, II-A, II-B, III according to Neer's classification. 3. Fifty nine patients (61.4%) were associated with injuries of other parts and the most frequent associated fracture was tibial fracture and the most common associated soft tissue injury was cerebral concussion or contusion. 4. The methods of treatment: conservative management by using skeletal traction for 34 cases, surgical treatment by open reduction and internal fixation for 58 cases and A-K amputation for 4 cases due to populiteral artery injury. 5. Fifty nine cases were suitable for result analysis. The satisfactory result of surgical treatment was 63.4% and conservative treatment was 50.0% respectively. The factors affecting the final results were Type of fracture, severity of injury, and rigid internal fixation. 6. The main complications of the supracondylar fractures of the femur were delayed union (10.2%), infection (10.2%), and traumatic arthritis (13.3%). 7. Finally, the results of treatment depend largely on anatomical reduction, rigid fixation, early joint motion.

Sonographic determination of fetal gender was attempted prospectively in most pregnancies of more than 26 weeks. We stuided 193 cases of pregnancies with ultrasound for recent 9 months from June 1984 to Feb. 1985 atdepartement of radiology, Soonchunhyang university, Soonchyunhyang chunan hospital, and analysed ultrasonographicfinding of fetal gender. The results were as follows; 1. Overall accuracy rate for fetal gender is 90%. 2.Accuracy rate for male fetus is 97.8%. 3. Accuracy rate for female fetus is 88.2%.

PURPOSE: The authors investigated the ability of cardiac blood pool clearance rates(CBCR) of 99mTc-DiSiDA in the measure merit of functioning hepatocyte mass. MATERIALS AND METHODS: We measured the volume of Iobectomized liver after completion of postoperative scanning with CBCR of 99rnTc-DISIDA in 5 rabbits who the functional hepatic Iobectomy performed by ligation of hepatic artery, portal vein and biliary tracts. Regarding the measurement of CBCR of 99mTc-DISIDA, we set the time which was decreased to the half of the clearance amount of the cardiac radioactivity by hepatic extraction of 99mTc-DISIDA at the point of 50 sec after the renal peak of the radioactivity to prevent confusing with the blood dilution of the radioactivity, that have called DI-K50. RESULTS: The results were followed that the volumes of the functional hepatic Iobectomy in 5 rabbits were 25%, 25%, 41%, 52%, 75% and the residual functioning hepatocyte masses measured by CBCR of 99rnTc-DISIDA were preserved to 75. 1%, 70. 8%, 63. 0%, 52. 2%, 30. 8% respectively. CONCLUSION: we made decision that CBCR of 99rnTc-DISlDA was useful to evaluate the functioning hepatocyte mass.

Patients vary markedly in their responses to d-tubocurarine chloride. Despite an attempt to diminish the variation in responses to relaxants by standardizing experimental techniques, anesthetic concentration kept constant, acid-base status kept constant, premedication omitted, dosage calculated in terms of mg/sq meter body surface, the marked variation was found to persist. The dose related neuromuscular blocking effect of d-tubocurarine chloride was investigated using a rabbit common peroneal nerve anterior tibial muscle preparation. All experimental rabbits tracheas were intubated through tracheostomy under general anesthesia with Nembutal 40 mg/kg intravenously. Reapiration was controlled by a Harvard animal respirator. The body temperature was kept at 35-37 degrees C by a thermoblanket. The degree of neuromuscular block following intravenous d-tubocurarine chloride was measured by single twitch response. The common peroneal nerve was stimulated supramaximally using a square waves of 0. 2 msec duration at a frequency of 0.1 Hz, and each stimulus was repeated once every 10 seconds. The ratio of the twitch height was calculated. The results were as follows: 1) No neuromuscular blocking effect was observed with 0.1 mg/kg of intravenous d-tubocu- rarine chloride. 2) 100% of neuromuscular blocking effect was observed with more than 1mg/kg of intravenous d-tubocurarine chloride. This is 5 to 10 times higher than the human dose. 3) Dose related prolonged neuromuscular blocking effect was observed from d-tubocurarine chloride in rabbits.

BACKGROUND: To clarify the clinical significance of CEA and CA19-9 in patients with gastric cancer, we evaluated the correlation between tissue expression, the peripheral and the portal levels of these tumor markers, and ten clinicopathological factors, as well as the prognosis. METHODS: Surgical specimens from 40 patients with gastric cancer were examined by using immunohistochemical staining with anti-CEA and anti-CA19-9 monoclonal antibodies. Serum levels of CEA and CA19-9 in the portal and the peripheral blood were measured by using immunoradiometric assays. RESULTS: Positive values of the portal venous CEA were more common in patients with lymph-node metastasis, distant metastasis, and lymphatic invasion than in those without these factors. Curative surgery was performed in 50.5% of the patients with high portal CEA levels and in 90.6% of the patients with low portal CEA levels. Positive values of the peripheral venous CEA were significantly higher in cases with lymph-node metastasis. The positive rate of CA19-9 immunohistochemistry was significantly higher in patients with distant metastasis and in non-curative surgery. The positive rate of peripheral venous CA19-9 was higher in cases with distant metastasis. The three-year survival rate of patients with negative tissue CEA was significantly higher than that of patients with a positive result. The peripheral venous levels of CEA and CA19-9 reflected the portal venous levels accurately. CONCLUSIONS: These results suggest that immunohistochemical examination of CEA in patients with gastric cancer is useful for the evaluation of the biological aggressiveness and progression of the disease and can be used for making a prognosis.
