The ankle joint plays important biomechanical role in erect position or ambulation. The ankle injury includes bony structures with articular surface, ligaments and soft tissue injury. So the goal of treatment is anatomical reduction of ankle mortise. Fifty two patients of ankle fractures which were admitted and treated in Seoul Adventist Hospital from January, 1980 to December, 1984, were analysed in the clinical and radiological aspect. The results obtained from this study were as follows; l. Of the 52 cases, male was 39 cases(75.0%) and female was 13 cases(25.0%). The average age of the patients was 33 years with range from 18 years to 75 years. 2. The most common cause of injury was traffic accidident. Nexts were fall down, sports injury, slip down and industrial injury in orders. 3. The most common type of the ankle fractures, according to the classification of Lauge-Hansen, was supination-external rotation type(40.4%). 4. 36 cases(69.2%) were treated with open reduction and internal fixation and 16 cases(30.8%) were treated with closed reduction. Poor outcome seemed closely related to the severity of the injury and degree of fracture displacement. 5. Accurate reduction and rigid internal fixation of the lateral malleolus without shortening was important factor. Classification of Lauge-Hansen was useful in the diagnosis and treatment of the ankle fractures.

The study was undertaken to assess the ventricular system of the brain in normal korean adults on the base ofCT. The computerized tomographic examinations of 334 Korean adults between ages of 15 to 50 years, performed atSeoul National University Hospital, were evaluated. The known to be a reliable indicator of the ventricular size.This ratio was measured at the level of the lateral, third and fourth ventricles respelctively. The shape of thequardigeminal and suprasellar cistern was analyzed. The resuls are as follows; 1. The cerebroventricular ratios ofthe lateral ventricle at the level of the widest bifrontal and bicaudate diameters were 0.30±0.04 and 0.14±0.02,respectively. The lateral ventricle was asymmetric in 12.6%, of which the left side was usually larger than theright. 2.There was correlation between the cerebroventricular ratio and age, i,e., with increase of age, the C-Vratio increased slightly. 3. The cerebroventricular ratio of the third ventricle was 0.03±0.01. 4. Thecerebroventricular ratio of the fourth ventricle in width and height was 0.14±0.02 and 0.10±0.03, respectively.The anteroposterior position index of the fourth ventricle was 0.42±0.04. 5. The quadrigeminal cistern showedU-shape in 23.4%. 6. The suprasellar cistern showed pentagonal shape in 61.1%, round in 28.4% and hexagonal in10.5%. 7. There was no significant difference between male and female according to the above results.

This study was carried out to investigate the light and electron microscopic findings of the livers of rats after an intraperitoneal injection of cadmium chloride. The Sprague-Dawley rats were intraperitoneally injected with cadmium chloride dissolved in water, once a day for three days. These animals were sacrificed at 1, 3, 8, and 24 hr after the last injection. Control groups of the rats were also sacrificed in the same manner. The liver was extirpated and examined by both light and electron microscopy. The results obtained are as follows: The parenchyma of the liver shows focal neutrophilic infiltration and spotty necrosis. The hepatocytes show fatty change, ballooning degeneration, swelling of the endoplasmic reticulum and mitochondria, increase numbers of secondary lysosomes and residual bodies. Focal patic venules and sinusoids of the liver are congested. The Kupffer cells are increase in number. Therefore, it can be concluded that the cadmium is directly acted to hepatocytes resulting in cellular injuries and deposits in the fat droplets of the cytoplasm of the hepatocytes, not Ito cells as previously suggeted.

Autoclaving the local anesthetic ampuls has been suggested as a safer method of sterilization. However the method and time necessary to sterilize the ampul has not been standardizzed, and the amount of deterioration of anesthetic agents by this method is unknown, and the effect of injection of the caramelized dextrose has not been determined. If ampuls are autoclaved with the spinal tray or set up, the ampuls are subjected to sterilization for a prolonged time which in turn causes caramelization of dextrose and possible deterioration. We have studied the effect of multiple autoclavings on pH of the drugs whichart used in spinal anesthesia, 1% tetracaine, 10% dextrose, 2% xylocaine and epinephrine at 134C, 36 psi for 5 minutes. Statistieal significance of the pH changes were observed by multiple autoclavings.

Total of 311 cases who were admitted to pediatric departmenr of Kyung Hee University Hospital from October, 1971 to December, 1975 were studied clinically about the cases in various age group. The results are as follows. 1) Convulsion was most frequent in children between 6months and 3years (38%), but it was least frequent in children from 10years to 15 years (7%). 2) The most common cause of convulsions in children was febrile convulsion(30.5%). 3) Tetanus (50.9%) was most frequent cause of convulsion in the neonatal period. 4) Febtile convulsion was most common in infants from one month to six months. 5) The most common cause of conculsions in infants from six months to three years was febrile convulsion (47.8%). 6) In children more than three years of age, idiopathic epilepsy was most frequent cause of convulsion (3 to 10 years and 10 years to 15years , 36%, 72.7% respectively).

Authors experienced a case of acute optic neuritis, 12 years old female patient, following scarlet fever which is rare among bacterial origin in ophthalmological aspects. On the first day of admission, the visual acuities of 0.04(N.C.) in right eye and 0.2 (N.C.) in left eye, blurring of disc margins (OU), central scotoma (OD), and high antistreptolysin O titer (A.S.T.O.) were noted. After bed rest and medical treatment with corticosteroid, penicillin, and vitamin B12 for two and a half months, the visual acuities and antistreptolysin O titer were recovered completely.

OBJECTIVE: To compare two testing protocols for evaluating range of motion (ROM) changes in the preloaded cadaveric spines implanted with a mobile core type Charite(TM) lumbar artificial disc. METHODS: Using five human cadaveric lumbosacral spines (L2-S2), baseline ROMs were measured with a bending moment of 8 Nm for all motion modes (flexion/extension, lateral bending, and axial rotation) in intact spine. The ROM was tracked using a video-based motion-capturing system. After the Charite(TM) disc was implanted at the L4-L5 level, the measurement was repeated using two different methods : 1) loading up to 8 Nm with the compressive follower preload as in testing the intact spine (Load control protocol), 2) loading in displacement control until the total ROM of L2-S2 matches that when the intact spine was loaded under load control (Hybrid protocol). The comparison between the data of each protocol was performed. RESULTS: The ROMs of the L4-L5 arthroplasty level were increased in all test modalities (p < 0.05 in bending and rotation) under both load and hybrid protocols. At the adjacent segments, the ROMs were increased in all modes except flexion under load control protocol. Under hybrid protocol, the adjacent segments demonstrated decreased ROMs in all modalities except extension at the inferior segment. Statistical significance between load and hybrid protocols was observed during bending and rotation at the operative and adjacent levels (p < 0.05). CONCLUSION: In hybrid protocol, the Charite(TM) disc provided a relatively better restoration of ROM, than in the load control protocol, reproducing clinical observations in terms of motion following surgery.
