In accidents, the spines are generally subjected to one of five types of violence; pure flexion, flexion and rotation, extention, vertical compression, or direct shearing force by Holdsworth's report. Flexion and rotational violence, so-called, unstable rotational fracture-dislocation results in paraplegia commonly. The treatment of the fracture-dislocations of the thoracic and lumbar spine had varied widely during the past 100 years, including conservative and operative treatment, but there is no definitive study that convincingly show the superiority of either operative or nonoperative treatment till now. Ten cases of the unstable thoracolumbar vertebral fracture or fracture-dislocations during the past two years were reported in this paper. In unstable types on the thoracolumbar vertebral fracture or fracture-dislocations, direct blow was the most common cause of injury and the thoracolumbar junction extending from T10 to L1 was the most common location of injury in this report. Three among four paraplegic patients were received flexion and rotational violence and the remaining one, direct shearing force. All four paraplegic parients were operated. Among them two cases, the one who was performed open reduction and simple wire fixation and the other open reduction and Harrington instrumentation, recovered almost completely except mild motor weakness of lower extremities. All cases complained of remaining back pain more or less without relation to the method of treatment.

Fractures of the phalanges of the hand are very common. Many are minor and likely to have a good result. However many other phalangeal fractures cause significant and prolonged disability. Non-union of the tubular bones of the hand are uncommon occurrence, but are often associated with functional deficits. The authors have reviewed 7 cases of non-union of the phalanges which were treated in the department of orthopaedic surgery, National Medical Center from 1978 to 1985. The results were summarized as follows: 1. The non-union of phalangeal bone was defined by clinical symptoms and signs and roentgenological examination. 2. The incidence of non-union of phalangeal bone fractures was 0.9% (7/771 cases.) 3. of 7 patients, there were 6 in male and 1 in female. 4. Non-union occurred more commonly in the second decade and the group between 10 and 30 years of age. 5. Seven cases, all were the right handed, but injury was developed in the left hands except two cases. 6. The causes of non-union were thought as open wound (7 cases), type of fracture (simple or comminution:3 cases), inadequate immobilization (4 cases) and overtraction (1 case). 7. of 7 cases, 4 cases were treated with bone peg graft and K-wire fixation and 2 cases with excision of distal fragment. 8. The clinical union was 9 weeks in average.

OBJECTIVES: To evaluate the association between working conditions and adverse pregnancy outcomes in Korea. METHODS: We obtained data on health history, lifestyle, housework and working conditions, such as shift work, hours standing, working time, job demand, lifting at work and at home, between August and September 2000, from self-reported questionnaires. A group of 344, occupationally active, pregnant women from 51 industries were studied. Of the women studied, 328 women were further interviewed by telephone between November 2000 and September 2001. Result : Compared with daytime work, shift work increased the risk for preterm birth (an adjusted risk ratio of 2.74, 95% CI=1.02-2.62) and low birth weight (an adjusted risk ratio of 2.74, 95% CI=1.02-2.62). A significantly increased risk was found for prolonged standing, with an adjusted risk ratio of preterm births of 6.80 (95% CI=2.01-23.0). There were no significant differences in the incidence of spontaneous abortion between the occupational working conditions, with the exception of a previous history of spontaneous abortion. CONCLUSION: These findings suggest that maternal working conditions, such as shift work and prolonged standing, contribute significantly to preterm birth and low birth weight.

The pulmonary cytology has reached a high level of accuracy. By the examination of the sputum and/or bronchial brushings, it is now possible to make a diagnosis in 70% to 90% of patients with cancer. Primary melanoma of the lung is very rare and there have been reported about 20 cases in the world literature. We present a case of primary malignant melanoma of the lung in a 61-year-old male diagnosed by cytologic examination of sputum, bronchial brushing and aspirated pleural fluid. Histologic examination of bronchoscopic biopsy and examination of the skin and other primary sites confirmed the diagnosis.

Biological behavior of malignant tumors has been assessed by morphological grading, clinical staging, and estimating other tumor markers. Recently DNA ploidy measured by flow cytometry and image analyser has been suggested as an additional useful indicator of the tumor behavior. In order to extract useful tumor cell-specific information in ovarian mucinous tumors, DNA contents and other morphologic parameters were measured by image analysis and DNA ploidy was also measured by flow cytometry. In all cases of cystadenoma, DNA diploidies were observed. In borderline malignancy, DNA diploidies were chiefly observed except one case of polyploidy. In true malignancy, DNA aneuploidies were observed except one case of polyploidy and two cases of diploidies by image analysis, and except four cases of diploides and one cas of polyploidy by flow cytometry. The statistical significance were observed in DNA ploidy pattern by image analysis. In nuclear areas, perimeters and major axis, statistical significance were not observed. These results suggest that DNA ploidy pattern are more or less independent parameter as an additional useful indicator of the histological grade of malignancy and that image analysis are better than flow cytometry in detecting DNA aneuploidy.

Anthrax toxin consists of three separate proteins, protective antigen (PA), edema factor (EF), and lethal factor (LF). PA binds to the receptor on mammalian cells and facilitates translocation of EF or LF into its cytosol. PA is the primary component of anthrax vaccines. In this study we purified PA from culture filtrates of Bacillus anthracis. The purification involved sequential chromatography through hydroxylapatite, DEAE-Sepharose CL-4B, followed by Mono-Q. The purified PA was judged to be homogeneous on SDS-PAGE, and consisted of a single polypeptide chain with a relative molecular weight of 85,000.
