The significance of measurement of the spinal canal size was well recognized in case of detection of intraspinal tumor as well as diagnosis of spinal stenosis. The measurement of sagittal diameter of the lumber spinal canal by plain x-ray film is not always easy. However, the new method designed by Eisenstein made the measurement of sagittal diameter of the lumber spinal canal by plain x-ray film very easy. In order to study the range of normal values of the sagittal diameter of lumber spinal canal in Korean adults, authors measured antero-posterior and transverse diameter of the lumbar spinal canal in 290 normal Korean adults by Eisensteins method. The results obtained are as follows: 1. Mean values of sagittal diameter of the normal Korean adults male was 17.37±1.05mm at Ll, 16.43±1.12mm at L2, 15.89±1.20mm at L3, 15.45±1.24mm at L4, and 17.34±1.13mm at L5 vertebra and in female, 17.41±1.23mm at Ll, 16.45±1.20mm at L2, 16.14±1.41mm at L3, 15.40±1.32mm at L4, and 17.25±1.20mm at L5 vertebra. 2. Mean values of transverse diameter of the normal Korean adults male was 23.54±1.18mm at Ll, 24.61±1.17mm at L2, 25.78±1.41mm at L3, 27.72±1.86mm at L4, and 30.42±2.23mm at L5 vertebra and in female, 23.06±1.45mm at Ll, 23.90±1.48mm at L2, 25.21±1.53mm at L3, 26.62±1.88mm at L4, and 29.70±2.41mm at L5 vertebra. 3. In transverse diameter, it was increased more and more to the lower lumber level, the widest at L5 vertebra. 4. In sagittal diameter, it was decreased less and less to the lower lumbar level, the narrowest at L4, and increased again at L5 vertebra. 5. The difference of sagittal and transverse diameter of lumbar spinal canal at each level of lumbar spine was very significant statistically. 6. The difference of the transverse diameter of the lumber spinal canal between male and female was significant statistically but that of the sagittal diameter was not. 7. The difference of the sagittal and transverse diameter between each age group was not significant statistically.

The purpose of this study was to investigate the gaps of bone-acetabular component interface, the initial mechanical stability and the effects of adjuvant screw fixation in the press-fitted two different shaped porous-coated acetabular components. Semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup were press-fitted with or without adjuvant screw fixation in 40 bovine femur. The gaps of bone-implant interface were measured in each radiography of all specimen and axial compression tests and rotational stability tests were performed using servohydraulic tension-compression machine. There was significantly smaller gap at polar 1/3 region in the specimen implanted with Trilogy cup. But the adjuvant screw fixation did not affect the amount of gap. There was no significant statistical difference in axial load and rotational stability test in each situations of fixation. This study demonstrates that the initial mechanical stability is not influenced by the shape of semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup and also independent of adjuvant screw fixation. But smaller gap of Trilogy cup at the polar 1/3 region indicates the possibility that less amout of wear debris of polyethylene or metal will be deposited and therefore less osteolysis or cup loosening will occur, but this hypothesis should be confirmed by the long-term clinical follow-up.

The diagnosis of osteosarcoma is based on both clinical, rediological and histopathological findings, but the majority of the patients with osteosarcoma can be diagnosed with a reasonable degree of confidence from the appearance of the lesion on the plain X-ray film. The combination of soft tissue mass and calcification, increased intramedullary radiodensity, cortical bone destruction,and marked periosteal reaction such as Codmans triangle and sunburst reaction is the radiographic hallmark of osteosarcoma, Among the above mentioned radiological findings, the presence of soft tissue mass with calcification can be so strongly suspected to be nearly diagnostic on the X- ray examination alone. The author performed radiological analysis of 40 cases of osreosarcoma which was experienced at the Department of Orthopedic Surgery, College of Medicine, Korea University including other hospitals from 1975 to 1980 and particulary observed correlation between the soft tissue mass with calcification and other radiological findings. The results obtained as follow: 1. Of the 40 cases, soft tissue mass with calcification were observed in 32 cases(80%), cortical destruction in 31 cases(77.5%), periosteal reaction in 24 cases(60%), sunburst reaction in 23 cases(57%) and Codmans triangle in 21 cases were observed. 2. Of the 40 cases, 23 cases(57.5%) were osteoblastic, 12 cases(30%) of osteolytic and 5 cases(12.5%) of mixed type. 3. The shadow of soft tissue mass with calcification was observed 11 cases(91.7%) among 12 cases of osteolytic type, 28 cases(91%) among 31 cases of cortical destruction, 21 cases(87.5%) among 24 cases of periosteal reaction, 20 cases(86.9%) among 23 cases of sunburst reaction and 18 cases (85.7%) among 21 cases of Codmans triangle.

Prisms have been used as tools with which to treat and diagnose many diseases in strabismology. But, because of prismatic distortion and dispersion, the visual acuities are declined. The purpose of this study is to show the relationship between prismatic effect and visual acuity degradation. Visual acuities were measured through a series of prisms of CR-39 to quantify the blur induced by prism. The mean visual acuities of myopias and amblyopias(with or without correction), and emmetropias were reduced as prism diopters were increased. The declines were linear. There was no significant difference among the declines of visual acuities of each group. Whenever to prescribe prisms and to test with prisms, we should remind that prisms could reduce visual acuities.

Emphysematous cholecystitis is an uncommon condition which may mimic acute cholecystitis. But it differs from acute cholecystitis in its relatively greater frequency in men and diabetics and has graver prognosis. The condition is diagnosed by demonstration of air in lumen,wall of gallbladder and/or pericholecystic space using a variety of radiographic techniques: simple abdominal radiography, ultrasonography and CT scanning. One illustrative case is presented herein and the pertinent literature is reviewed.

It has been studied that a variety of fauna and flora are sensitive biological indicators which reflect the severity of regional pollution of heavy metals, but in the center of part of Taegu city the controversial issue of lead poisoning attributable to the atmosphere which contains an increased concentrations of lead has been raised recently, it is usually hard to find suitable plants or animal in the areas with heavy traffic. Pigeons are ubiquitous in and around Taegu city area, inhabiting even the most densely populated areas with heavy traffic with its small body size, high metabolic turnover, and rather limited mobility, a pigeon, as a biological indicator is expected. This study was conducted to monitor lead pollution in the Taegu and kyongju city in Korea. We measured the lead content of the various tissue of three groups of feral pigeon(Columbia livia) and soil and atmospheric lead concentration. First group was obtained io heavy traffic area in Taegu City, the second group was obtained a park in Taegu city and the third group was obtained light traffic area in kyongju city. The air and soil lead concentration of heavy traffic area in Taegu city was 0.11 microgram/m2, 4.96 microgram/g, that of park in Taegu city was 0.05 microgram/m3, 2.65 microgram/g and that of light traffic area in kyonngju city was 0.03 microgram/m3, 0.01 microgram/g. The lead content of lung, blood, kidney, femur and liver of feral pigeons in heavy traffic area in Taegu city was significantly higher than pigeons obtained in a park in Taegu city and low traffic density area in Kyonfju city(p<0.01). But stomach lead content of three group did not reflect a significant difference. In this study positive correlation was found between atmospheric lead concentrations and the concentration of lead in the pigeon's lung(r=0.5040, p<0.001), blood(r=0.3322, p<0.01), kidney(r=0.4824, p<0.001), femur(r=0.7214, p<0.001) and liverer (r=0.4836, p<0.01). we can also found positive correlation between soil lead concentrations and the concentration of lead in the pigeon's femur(r=0.4850, p<0.001), kidney(r=0.4850, p<0.001) and liver(r=0.4386, p<0.01). In the pigeon`s tissue there were significant correlations between concentration of lead in the blood and kidney(r=0.4818, p<0.001), femur(r= 0.6157, p<0.001) and liver(r=0.3889, p<0.001). In conclusion, at the heavy traffic area in Taegu city, lead concentrations found in the atmosphere and soil are reflected in the lead concentrations of different tissue of urban pigeons. It is suggested that the tissue of pigeons can be good biological indicators of environmental lead pollution.
