From May, 1971 to June, 1984, we performed extensive saucerization on the chronic osteomyelitis of long bones eradicating all pathologic foci; not only sequestra but sclerotic involocurum and necrotic original cortex embeded by new bone, which was different from the conventional methods such as sequestrectomy or guttering in its extensiveness. Clinical analysis on the base of radiologic evaluation after saucerization was done on the 16 patients; for average 5 years of follow-up. The results obtained were as follows; 1. The angulatory deformity of the long bones after pathologic fracture complicated by the chronic osteomyelitis was not corrected satisfactorily due to the bony sclerosis or hyperostosis at the fracture site, especially in cases of posterior or medial angulation. 2. The recurrence was closely related to the persisting non-sequestered original cortical lesion after incomplete saucerization, which was embeded by the new bone. So to prevent the recurrence the non-sequestered original cortical lesion must be removed completely. 3. The cortical defect after saucerization was restored completely in patients under the age of 14, but which was not the way in patients over the age of 16.

The Journal of the Korean Orthopaedic Association 1985;20(6):1067-1072
The first metacarpal base fracture is classified as extra-articular fracture, intra-articular fracture and epiphyseal injury. Intra-articular fracture was firstly described in 1882 by Bennett and Rolando described about Y shape comminuted fracture in the first metacarpal base in 1910. In 1938, Robert wrote about oblique fracture injured by first metacarpal base fracture. First metacarpal base fracture can be adjusted easily by C/R, but it is difficult to maintain the good axis. In case of fail of reduction, malunion, joint stiffness and traumatic arthritis can be shown as complications and finally some problems in grasping and pinching are resulted. Therefore, firstly the most accurate reduction, secondarily effective method to maintain the condition and thirdly the protection of limitation of motion are goal of treatment. Authors reviewed 17 cases treated by 0/R & C/R for the past 5 years from 1975 to 1980 at National Medical Center, especially reviewed the cases of which observation more than 1 year was possible. The results were as followings: 1. The incidence of first metacarpal base fracture was 1.0% of all fractures & dislocations. 2. Out of 17 cases, there were 14 male and right side 9 cases and left side was 8 cases. 3. The most common case of fracture was injury at work and traffic accident, sports injury, slipping down and falling down. 4. The method of treatment were C/R & percutaneous pinning in 10 cases and 0/R & K-wire fixation were 7 cases. 5. The result of treatment showed 8 excellent, 1 good, 1 fair, out of 10 cases of C/R and percutaneous pinning. In 0/R and K-wire fixation, 4 excellent, 2 good, and 1 fair showed out of 7 cases. 6. Soft tissue infection was appeared from 1 case of open fracture which accompanied second metacarpal fracture as complication and it caused adduction contracture in first web space.

T The Flexor tendon injury caused by trauma of hand and forearm is commonly reported and earlier treatment for trauma is recommendable. But in many cases, earlier treatment is often not possible due to degree of injured tissues and infection. Specially in cases of severe trauma and damage of tendon sheath and pulley, the solution of limitation of motion is still remained as a difficult problem up to present due to scar tissue adhesion to surrounding tissues even after the primary treatment. The Department of orthopaedic surgery of National Medical Center during four years from 1981 to 1985 have treated 22 patients (27 fingers) of old flexor tendon injuries with tendon reconstruction and followed up more than for 6 months for clinieal study arrd the results ase as follows: 1. The old flexor tendon injuries are composed of 18 patients of the first decade and the second decade, especially in male. 2. The main causes of injury were deep lacerations by sharp objects (12 patients, 55.6%) and crushing injuries (9 patients, 40.8%). 3. Tendon injuries were mostly occurred in the index and ring finger. The incidence rate was equal between the 2 fingers, 25.7% representatively. Most of the injuries (21 cases, 77.8%) occurred in the zone II (Kleinert classification). 4. According to Boyes' classification, Grade 2 was 16 patients (19 cases): Grade 4, 3 patients (4 cases): Grade 3, 2 patients (3 cases): and Grade 5, 1 patient. 5. The operation method in zone II was free tendon graft in 10 cases and staged tendon graft in 7 cases. 6. The timing of operation depends on whether the open wounds were completely healed or not as well as subsidence of swelling. In case of swelling. In case of stiff fingers normal range of motions should be restored by vigorous exercise before operation. 7. According to the assessment based on strickland and Glovac, 20 cases out of 22 cases (13 cases of free tendon graft and 9 cases of staged tendon graft were satisfactory result.

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.

Based on the histopathologic findings of the lacrimal gland tumor, the lesion is classified as either epithelial or nonepithelial tumor. 22% of lacrimal gland lesions were primary epithelial neoplasm. 4%of epithelial tumor of lacrimal glands were primary malignant tumor. Squamous cell carcinoma arising from pleomorphic adenoma of lacrimal gland is a very rare(0.4%). Inspite of surgical intervention, postoperative radiation and chemotherapy, the mortality and recurrence rate of the carcinoma ex pleomorphic adenoma of lacrimal gland is very high. We report a case of squamous cell carcinoma ex pleomorphic adenoma of lacrimal gland, which was completely removed via lateral orbitotomy with bicoronal incision and had no major complication or recurrence.

The writers performed Sbarbaro type total hip replacement arthroplasty on two cases with degenerative arthriris of both hips complicated by avascular necrosis of the femoral head. In each case, the procedure was carried out on the worse hip, while in one case a standard femoral head prosthesis was inserted to the less severely involved hip. The Sbarbaro type prosthesis consists of a modified Austin Moore head component and an acetabular cup with tynes that fix the metal to the acetabulum and does not require the use of cement. The initial results in both cases, evaluated by the method of D'Aubigne and Postel, are as follows; Grade 5 for pain(pain both slight or intermittent), Grade 5 for motion(very good or 161 to 210 degrees), and Grade 5 for ability to walk(very good; no cane or crutch but a slight limp).

To build and to manipulate clinical data in one of the important works in the hospital. In order to accurately append the data and to quickly find and display the informations as the user need, we developed a software program running on the personal computer. Our system largely consists of four parts; registration of the clinical and departmental data, retrieving tool of articles in the medical journal, collection of special data for clinical survey and display system of the various reports. In our experiences, we consider the key factors for systemic management of clinical rearch data base as the follows; work analysis for data processing, design of data base, coding and classification of basic data and technique of registeration. Of these standarized coding system of the orthopedic diseases appeare to be of it most importance.

The myocardial lesions by the injections of isologous heart emulsion were produced in rabbits, and organspecific isoimmune mechanism in the genesis of myocardial lesions was studied by fluorescent antibody technique and demonstration of antibodies against isologous heart muslce. Four groups of rabbits were subjected to normal untreated control, adjuvant control, injection of isologous heart homogenate aIone and injection of heart homogenate plus Freund's adjuvant. Injection of isologous heart homogenate produced circulating anti-heart muscle antibodies which were enhanced by addition of Freund's adjuvant in heart homogenate. Histologic lesions in the heart consisted of interstitial edema, mononuclear cell infiltration, degeneration of myofibers and stromal reaction. Fluorescent antibody technique on myocardial lesions showed presence of anti-heart antibodies in parallel with the degree of myocardial lesions as well as with titre of circulating antibodies. Skeletal muscle and other organs showed neither histologic alteration nor precence of anti-heart antibodies. These data clear1y indicated that the lesion in the myocardium produced by isologous heart homogenate was developed by organ-specific isoimmune reaction.
