To investigate the properties and mechanism of PAF and TNF on the synthesis of prostaglandin E2 in human amnion, primary monolayer culture method was used for human amnion cell incubation. Amnion cells were incubated with various concentrations of PAF or TNF in Ca++ containing medium for various duration. Then PG E2 concentrations were measured by RIA and analyzed for the effect of PAF and TNF on PG E2 production according to their doses and incubation time. To test the role of Ca++ in E2 production, Ca++ free medium, Ca++ -channel antagonist and cyclo-oxygenase inhibitor were substituted or added in incubation medium. Following results were obtained. The synthesis of PG E2 was significantly enhanced by PAF of 10(-6) mol/L. The TNF also stimulated PG E2 synthesis at concentration of 10(-6)g/ml. The maximal level in PAF(10-6mol/L)-stimulated release of PG E2 was observed after 16 hours in incubation. The TNF(10(-6)g/ml)-induced PG E2 release was maximal after 24 hours of incubation. Combined application of PAF and TNF produced positive effect in PG E2 production. PAF or TNF stimulated-PG E2 production in Ca++ -free media was much lower than that of Ca++ -containing media. The PAF-stimulated PG E2 release was significantly inhibited by Ca++ -channel antagonist but TNF-stimulated PG E2 release was not effected by Ca++ -channel antagonist or cyclo-oxygenase inhibitor. It is strongly suggested us that both PAF and TNF enhance PG E2 release by amnion cell, although Ca++ -channel opening is essential only for PAF stimulation.

We analysed 26 cases of pyogenic osteomyelitis of the spine who were treaed at Younsei University Hospital during 25 years from January 1952 to August 1977 by operative or conaervative treatment. The diagnosis of pyogenic osteomyelitis of the spine is not easy and very confused. The cause and entry of the offending organism is mainly by venous drainage from the genitourinary and lower extremity circulation and the next is direct spreading from the adjacent focus. The typical clinical symptom is severe pain and tenderness over the lesion accompanied by febril history and the clinical course is relatively rapid than tuberculosis of the spine. In blood examination leukocytosis is uncommon but it showed relative increase of neutrophils in 62%, and erythrocyte sedimentation rate in 89%. Radiological findings are narrowing of joint space, erosion and/or destuctive change of vertebral body, vertebral marginal sclerotic change, and new bone formation and less frequently abscess shadow. The results obtained from this study were as follows, 1) The incidence of pyogenic osteomyelitis of the spine among total cases of the pyogenic osteomyelitis was 2.5% and the ratio of the pyogenic osteomyelitis of the spine to the spine tuberculosis was 2.8%. 2) The sexual incidence was in 11 and 15 each male and female. and the avrage, prevalent age was 34 years of age. 3) The pathogenic organism was isolated in 20 cases from the diseased focus during surgical procedure; stapyhloccus in 16 cases, pseudomonas in two and in a case of E.coli and proteus each. 4) The lumber vertebrae was mostly involved, i.e.lumbar in 11 cases, cervical in four, thoracic in nine, lumbosacral and sacrum in one each. 5) The operative treatment was performed in 23 cases and conservative in 3 cases with the satisfatory result in all cases. 6) We conclude that the focal curettage with anterior interbody fusion through anterior approach was better than the conservative treatment.

Collagen is the major structural protein in the human body, especially in connective tissues. There are more than 13 types of collagen. Among them, type II collagen is a main component of articular cartilage structure. Altered immunological conditions against type II collagen may be closely related to the pathologic conditions of joint, especially arthritis. Since 1977, animal model for collageninduced arthritis(CIA) has been developed and used in the investigation of arthritis. In those animals, high titers of anti-type II collagen antibody were noticed. Pathologic findings were similar to rheumatoid arthritis of human, which suggested that rheumatoid arthritis might be one of the autoimmune diseases. There had been many reports about elevation of serum and synovial level of anti-type II collagen antibody in rheumatoid arthritis patients. But majority of them did not discriminate the antibody titers according to the type of immunoglobulin(i.e. IgG, IgM). And the question whether the elevated antibody titers are cause or effect of the arthritis is still in controversy. In this study, the serum levels of anti-type II collagen antibody were determined in 82 persons(35 degenerative arthritis patients, 24 rheumatoid arthritis patients and 22 normal controls without any joint problem) via ELISA method. In each person the serum IgG, IgM and IgG+M+A antibody levels against bovine type IIcollagen and chicken typeII collagen were determined individually. Statistical evaluation of these data among degenerative arthritis group, rheumatoid arthritis group and normal control group was performed. The results were as follows; 1. Degenerative arthritis group revealed significant elevation of anti-type II collagen antibody(IgG, IgG+M+A) compared to normal control(p < 0.05). 2. Rheumatoid arthritis group showed significant elvation of IgM and IgG+M+A compared to normal control. 3. Between degenerative arthritis and rheumatoid arthritis group, no sigificant difference was noticed. 4. Rheumatoid arthritis group showed significant increase of IgM antibody level compared to normal control. 5. Female rheumatoid arthritis group showed significant increase of IgM level compared to female degenerative arthritis group. These findings suggested that the elevation of anti-type II collagen antibody titer is not specific for rheumatoid arthritis and related with general pathologies destroying articular cartilage. And it is suggested that anti-type II collagen antibody associated with rheumatoid arthritis is mainly IgM proportion, especially in female patients. So further investigation of anti-type II collagen antibody associated with rheumatoid arthritis is needed to target IgM antibody.

The goal of total knee replacement is to relieve pain, to stabilize joint movement and to correct deformity. It is indicated for patients with rheumatoid arthritis, osteoarthritis and severe post-traumatic arthritis. The author analyzed 71 patients(106 cases), who received the PFC type of total knee replacement from August 1992 and the results were as follows; 1. Among the 71 patients, male was 8 patients and female was 63 patients whose average age was 56 years and average follow up period was 24 months, ranged from 8 months to 3 years 8 months. 2. Rheumatoid arthritis was the most common cause with 31 patients(56 cases) followed by osteoarthritis with 39 patients(49 cases). There was also one patient(1 case) that showed bony union of the knee due to old tuberculosis. The average duration of the illness was 12 years and the average weight of the patients was 57.7kg. 3. Flexion contracture decreased from an average of 21 degrees to 5 degrees after the operation. The range of motion increased from an average of 92 degrees before the operation to 117 degrees afterwards in cases of rheumatoid arthritis and decreased slightly from 108 degrees to 106 degrees in cases of osteoarthritis. 4. The tibiofemoral angle was corrected from an average 1.5 degrees varus before the operation to an average 6.7 degrees valgus after operation. Eighty seven percent of patients with rheumatoid arthritis showed valgus deformity and seventy eight percent of degenerative osteoarthritis patients showed varus deformity preoperatively. 5. Radiographically, the joint line position shifted an average 2.3mm in rheumatoid arthritis and an average 0.3mm in osteoarthritis. The component position, the femoral flexion was an average 89.6 degrees in the anteroposterior view, an average 87 degrees in the lateral view. 6. The thickness of the patella measured in the operating room of 61 cases was an average 21mm and after resection of patella, the remaining bone measured an average of 13.6mm. 7. To achieve soft tissue balance, 29 patients(33 cases) underwent medial stripping and 23 patients(30 cases) had patella lateral release. 8. The Insall Knee Rating Score was used to evaluate the results. The results were 69 cases excellent, 33 cases good, 3 fair and 1 poor. Ninety two percent of the patients had good or excellent results in average 24 months follow-up. 9. The complications consisted of one case of delayed deep infection, one case of patellar subluxation and one case of supracondylar fracture of the femur.

BACKGROUND: Tuberculosis itself causes not only lung parenchymal destruction but also pulmonary vascular damage. Secondary emphysema also causes pulmonary vascular damage, which can develop as a late sequela of pulmonary tuberculosis. Therefore, pulmonary circulatory impairment tends to be more severe in post-tuberculosis emphysema than in primary emphysema. In post-tuberculosis emphysema, the right ventricular function may play an important role. However, little information regarding the right ventricular function is available. The purpose of this study was to evaluate and compare the right ventricular function between post-tuberculosis emphysema and primary emphysema. METHOD: Post-tuberculosis emphysema(PTE) or primary emphysema(PE) was diagnosed by history, HRCT finding and pulmonary function. Twenty patients with post-tuberculosis emphysema were matched with 20 patients with primary emphysema according to both FEV1 and FVC. Arterial blood gas analysis and echocardiography were done at rest and immediately after symptom-limited exercise. The right ventricular function was evaluated with the right ventricular ejection fraction using a modification of Simpson's method. RESULTS: There was no significant difference inthe demographics and pulmonary function between the two groups. In post-tuberculosis emphysema, the PaCO2 was higher (42.9±4.7 vs 38.8±3.1 mmHg at rest ; 47.9±7.0 vs 41.1±5.9 mmHg after exercise ; p<0.01) and the right ventricular ejection fraction was lower (57.6±6.5 vs 61.4±4.7 % at rest ; 51.1±10.8 vs 59.8±6.6 % after exercise ; p<0.01) both at rest and after exercise. The PaO2 after exercise was also lower (65.7±12.6 vs 80.2%±14.4 mmHg, p<0.01), while the PaO2 at rest tended to be lower(82.9±12.0 vs 87.8±7.5, p>0.05). In both groups, right ventricular ejection fraction correlated with the PaO2 after exercise(PTE r=0.536, PE r=0.557), and the PaCO2 at rest(PTE r=-0.576, PE r=-0.588) and after exercise(PTE r=-0.764, PE r=-0.619). CONCLUSION: Impairment of the right heart function and gas exchange were more serious in post-tuberculosis emphysema than in primary emphysema, and gas exchange may be influenced by the right ventricular function in post-tuberculosis emphysema.

The differential diagnosis of atypical mycobacteriosis caused by atypical mycobacteria (with the exception of Mycobacterium tuberculosis, Mycobacterium bovis, and Mycobacterium leprae) which are widly distributed in soil and water, from pulmonary tuberculosis is possible only when atypical mycobacteria are isolated and identified. In this investigation, attempts were made to isolate atypical mycobacteria from persons registered as tuberculosis patients in the Anyang Health Center in Anyang City, Kyungki province, Korea. Biological and biochemical tests were performed for the atypical mycobacteria isolated from these patients, also retrospective analysis of clinical and X-ray findings of the patients with bacteriologically confirmed atypical mycobacteriosis were done. The results can be summarized as follows; 1. 103 strains of mycobacteria were isolated among 334 sputum samples from patients. 2. Among the isolated mycobacteria, 10 strains (9.7%) were found to be an atypical mycobacteria and 93 strains (90.3%) were tubercle bacilli of human type. 3. On the basis of Runyon's grouping of atypical mycobacteria, there were 3 strains (30.0%) of scotochromogen and nonphotochromogen respectively, 4 strains (40.0%) of rapid grower, and no photochromogen. 4. By biochemical tests, 3 strains of scotochromogen were identified as Mycobacterium scroful-aceum (2 strains) and Mycobacterium szulgai (1 strain) 3 strains of nonphotochromogen were Mycobacterium avium-complex (2 strains) and Mycobacterium terriae (1 strain), and 4 strains of rapid grower were Mycobacterium fortuitum (3 strains) and Mycobacterium chelonae. 5. In drug sensitivity tests, all 10 strains isolated atypical mycobacteria showed resistance to various concentration of INH and SM and low concentration (10 mcg, 40 mcg and 50 mcg) of EB, TH, and CS, and were sensitive to only high concentration (20 mcg and 100 mcg) of EB, TH, CS, and RFP. 6. In analysis of clinical findings by the patients with bacteriologically confirmed atypical mycobacteriosis, it was found that clinical symptoms of these patients appeared not to be mild than those of patients with pulmonary tuberculosis. The patients with atypical mycobacteriosis had been treated for pulmonary tuberculosis for a long time and they showed no improvement.

The incidence of pediatric dermatoses shows a tendency to increase inspite of medical development and environmental improvement. Pediatric dermatoses must be regarded as separate disease entities because child skin differs from adult skin in its structures and functions. Also to be noted are the special, characteristics of the child skin during the growth period. 11,447 childhood patients who had visited the demantologic department of Soon Chun Hyang Hospital, from 1975 to 1980, were analysed. in order to compile the current statistics on the tendencies of pediatric skin dises in Korea. The results are summarized as follows; l. Among the 34, 472 outpatients, 11, 447 were pediatric patients, comprising 33. 2% of the total figure. 2. In order of frequency, the most common dermatoses were atopic dermatitis, contact dermatitis, impetigo contagiosum, molluscum contagiosum, dermatophytosis, scabies, folliculitis, urticaria, varicella and insect bite. 3. The majority of childhood derrnatitis(65.5%) were shown to develop in the preschool age group, with the peak incidence falling in the 0-3 year age group (41.4%) 4. In analysis of the male: female frequency ratio, the dermatoses which showed a greater male frequency ratio were atopic dermatitis, contact dermatitis, impetigo contagiosum, scabies, insect bite, urticaria and miliaria. The dermatoses in which the female ratio was greater were seborrheic dermatitis, acne and hemangioma.

Although the incidence of tuberculous arthritis of the hip is being decreased with improvement of hygiene and preventive measures and chemotheraphy, it remains as important disease in orthopedic surgery. In order to evaluate which treatment is best in the view of eradication of the tuberculosis and preservation of the function, seventy two patients of tuberculous arthritis of the hip who were treated at the Department of Orthopedic Surgery, Seoul University Hospital for periods of 14 years between January 1970 and August 1983 were analysed clinically. The results are as follows: 1. Age distribution showed that patients below 15 years were thirty (41.7%) and those above 16 years were forty two (58.3%). 2. Onset of the symptoms above 1 year occupied forty two patients (58.3%). 3. Duration of follow up is between 1 year and 14 years with average duration of 3.5 years. 4. Recurrence rate according to the modality of treatment was 12.9% as 4 cases among 31 cases of hip fusion group, 15,2% as 5 cases among 33 cases of synovectomy group, and 28.6% as 2 cases among 7 cases of conservative group. 5. Follow up of the functional evaluation of the hip was 92.9% of “above Fair” as 26 cases among 28 cases of synovectomy group, 60% of “above Fair” as 3 cases among 5 cases of conservetive treatment group, and 25.7% of “above Fair” as 9 cases among 35 cases of hip fusion group. 6. Although the recurrence rate of synovectomy group is a little higher than that of hip fusion group, synovectomy is a better treatment in the view of the preservation of the function of the hip considering Korean life style.
