We reviewed 35 patients who received an operation for the Spondylolisthesis from July 1980 to July 1985. The follow-up period between operation and evaluation was at least 14 months and average 32 months. we obtained the following results. 1. The age distribution was from 23 years of age to 70 years of age and the prevalent decade was at the 5th. 2. Sex difference showed male 9 cases and female 26 cases, that is, female preponderance about 3 times. 3. 24 cases were isthmic type and 11 cases were degenerative type. The ratio between isthmic type and degenerative type was about 2: l. 4. Isthmic type was found at the 4th and 5th decades frequently and degenerative type was at 5th and 6th decade frequently. 5. The displacement between L4 and L5 was 21 cases and the displacement between L5 and sacrum was 14 cases. 6. In isthmic type, the displacement between L4 and L5 was 11 cases and the displacement between L5 and sacrum was 13 cases. In degenerative type, the displacement between L4 and L5 was 10 cases and the displacement between L5 and sacrum was 1 case. So the isthmic defect occurred at 2 levels almost equally and degonerative type occurred at L4-5 predominantly. 7. Overall results are excellent 2 cases(6%), good 29 cases(82%), fair 2 cases(6%), and poor 2 cases (6%).

Thirty-three cases of the fracture of the femur and tibia on the same limb were treated at the Orthopedic Department of the Chosun University Hospital during the period from January 1977 to December 1983. The following results were obtained. 1. The incidence of trauma was high in the young man, most frequent in the third decade (45.4%). 2. The most common cause of the fracture was traffic accident (81;8%). 3. The most common shape of the fracture was comminuted in both femur and tibia. 4. The common fracture site were middle one-third in both femur and tibia. 5. Eight patients were treated by conservative means on both femxr and tibia. The patients were treated by internal fixation on femur and by conservative means on tibia. Internal fixation was .done in ten patients on both femur and tibia. Two patients were treated by inteinal fixation on tibia and by conservative means on femur. Three patients were amputated. 6. Average healing time of fracture was 21 weeks in femur and 24.2 weeks in tibia. 7. Functional end results were assessed and rated with satisfactory results in rigid internal fixation of the femur and tibia.

Speech characteristics of cleft palate have been reported previously by hypernasality disorders. However, some cleft palate patients suffered from articulation disorders although they were taken surgery at an early time. Misarticulations of cleft palate patients are caused by abnormal lingual-palatal contacts. Traditionally, the Palatograpy has been used to see the lingual-palatal patterns. However, on this study, the Electropalatography(Palatometer) was used to investigate the comparison with lingual-palatal patterns between normal adult and cleft palate adult. The Nasometer model 6200-3 was used separately to measure the nasalance for cleft palate patient. The acoustic characteristics of cleft palate patients with respect to the palatographic patterns were examined by Computerized Speech Lab(IBM). The dental reflector was applied to measure the nasal airflow when cleft palate patient uttered. Test words were composed of meaningless mono syllabic words VCV (V: low center vowel /a/, C: alveolar stop, velar stop, affricate, fricative and lateral sounds). The subjects repeated the test words 10 times for statistic analysis. As a result of the palatographic patterns and the burst durations for stop consonants and the durations for fricative consonants, the cleft palate patients showed broader contact area, longer burst durations and fricative consonant durations than normal. It means that the cleft palate speech showed more tenseness of consonants than normal. By palatographic patterns, the misarticulation of cleft palate patient showed as follows : (1) Lingual-palatal contact of alveolar stop showed the palatalized misarticulation. (2) Lingual -palatal contact of velar stop moved forward in comparison with normal. However, posterior lateral contact areas were broader than normal contact area. (3) Lingual-palatal contact of affricate moved backward with narrower constriction than normal. (4) Fricative consonant showed lateral misarticulation.

In order to elucidate the biological effects of pulsating magnetic field in in vitro culture system we designed a pulsating magnetic apparatus using 120 Hertz, 24 Volt direct current. It can generate 63~225 Gauss in the experimental area of 90 mm petri dish, and has little thermal effect on the culture media in 37.5oC, 5% CO2. Human osteogenic sarcoma (HOS) cells were cultured in the pulsating magnetic field and the nuclear changes of cultured cells were observed routinely by hematoxylin staining, and apoptotic change was detected by ApopTag staining using both peroxidase and fluorescein labelings. Compared to the control group which formed well organized whorling pattern of HOS cell line in 3 days culture, the HOS cells cultured in the pulsating magnetic field for 12 hours or 24 hours grew irregularly and showed increased number of apoptotic cells. When the flow of pulsating magnetic field was interrupted by insertion of strong permanent magnetic bar (1000 Gauss, 5530 mm) beneath the petri dish during in vitro culture, the area of sparse pulsating magnetic field showed active proliferation and aggregation of HOS cells even in 24 hour exposure group. These data suggest that the pulsating magnetic field may play a role in inducing growth retardation and apoptosis of HOS cells. Furthermore, the hazardous effects of pulsating magnetic field can be lessened or nullified by the interruption of pulsating magnetic field with a strong permanent magnetic bar.

The authors made an attempt to classify the supracondylar extension-valgus fracture according to the direction and location of the fracture line based on the radiographic manifestation. This new classification helps to dictate the model of treatment, possible sequence of reduction and the causes of deformity of the elbow after treatment. During the last 12 years of this study, 200 supracondylar fractures of the humerus were treated in the Kyung Hee University Hospital. Of the cases 82 were extension-valgus fractures. The results were as follows: 1. The supracondylar extension-valgus fracture were classified into 5 types: Type I: fish-tail fracture (14 cases) Type II : obtuse fish-tail fracture (27 cases) Type III: oblique fracture (16 cases) Type IV: oblique fracture with comminution of lateral column (14 cases) Type V: Transverse fracture (11 cases) 2. The displacement of the distal fragment in the fish-tail fracture is severe but it can be reduced easily by manipulation. Once reduction has been obtained, the fracture is stable and maintained by a long arm cast with acute flexion of the elbow alone. There is no need of percutaneous pinning. Among 14 cases of type I fracture there was no cubitus varus deformity. 3. The line of the obtuse fish-tail fracture lies distal to fish-tail fracture. This is unstable so it is necessary to percutaneous pinning. 4. The oblique fracture is produced by the hyperextension of the elbow and degrees of the obliquity of the fracture line were 12 to 20 degrees (Av. 14 degrees). The valgus angles in opposit elbows were 9 to 25 degrees (Av. 16 degrees). The forearm must be pulled into valgus position during the reduction of the fracture. 5. Type IV fracture occures under 4 years old, and more commonly in girls. This is unstable, so it is necessary to percutaneous pinning.

Chusid et al proposed diagnostic criteria of hypereosinophilic syndrome (HES) that remain valid today. These were, (1) a sustained peripheral blood eosinophil count of more than 1500/L present for longer than 6 months ; (2) no evidence of other apparent causes for eosinophilia, and (3) presumptive signs of parenchymal organ involvement. Any organ system may be affected in HES, but the most severe clinicopathological involvements are of the heart and nervous system. Although multiple organ systems may be involved, the most common cause of morbidity and mortality is cardiac involvement with extensive fibrous thickening of the endomyocardium and overlying thrombus. We report a case of acute peri-myocarditis with eosinophilia, which was confirmed as eosinophilic myocarditis by endomyocardial biopsy, with literature review.
