In order to observe the complement fixation test and immuno-diffusion test of paragonimiasis, the sera taken at 10 days intervals up to 150 days from cats infected with Paragonimus westermani were examined by the above two immunological methods. The resultant findings were as follows: The complement fixation test showed positive reaction 20 days after the infection with 20 metacercariae, and 40-50 days after the infection with 10 metacercariae. The highest titer was observed 110 days later following the acceleration at 80 days later. In immuno-diffusion test, one are appeared 30 days after the infection with 20 metacercariae, but 60 days after the infection with 10 metacercariae. However, more than two arcs were observed since 70 days after infection. A relatively wide band appeared by the antigens of Fresh worm material and Somatic material. But relatively clear precipitin lines were observed in the diffusion test with V.B.S. antigen, increasing to 3-4 arcs after 110days. In general, complement fixation test showed earlier and higher sensitive reaction than immuno-diffusion test, and was considered to be more valuable method forr immunological diagnosis.

The results of cementless total knee arthroplasty(TKA) have improved steadly during the past decade due to development of design, fixation and surgical technique. We analyzed the results of 45 total knee arthroplasties performed with Anatomic Modular Knee(AMK) prosthesis at the department of Orthopedic Surgery, Yonsei University College of Medicine between June 1989 and December 1991 and compared their results of rheumatoid arthritis(RA) and osteoarthritis(OA) patients. The follow up ranged from 2 years to 4 years and 2 months (average 2 years and 8 months). Using the Hospital for Special Surgery(H.S.S.) rating system and Knee Society(K.S.) clinical rating system, we found that the clinical results were similar for RA group(Average; H.S.S. 86.1, K.S. 81.2/74.4) and OA group(Average; H.S.S. 88, K.S. 87.8/77.1) even though the preoperative knee score was lower in RA group(Average;H.S.S.42.8) than OA group(Average;H.S.S. 57.7). The average age of RA patients was 14 years younger than that of OA patients. The improvement of range of motin and preoperative flexion contracture after TKA was remarkable in RA group. The radiologic evaluation based on Knee Society roentgenographic evaluation system revealed proper alignment of all component and no definite radiologic loosening except 1 case in which postoperative deep infection had occurred. On the basis of this prospective clinical and radiologic review, we concluded that uncemented implantation of AMK prosthsis both in RA and OA patients was encouraging.

The present study was intended to examine the spectrum of radiographic patterns of the stomach associated withacute and chronic pancreatitis and their complications. Subjects served for the study consisted of 70 cases ofpancreatitis (36 cases in acute stage and 34 cases in chronic stage). Intramural and perigastic permeation ofextravasated pancreatic enzymes and secondary inflammatory reacation that follows are responsible for theardiographic change observed. 1. Generalized rugal thickening and particularly selective mucosal prominences ingreater curvature of body and antrum are characteristically seen in acute(14 of 36 cases

PURPOSE: To report the results of acetabular revisions performed with the cementless, hemi-spherical porous coated component supported by viable host bone and minimal allobone graft for acetabular deficiencies. MATERIALS AND METHODS: A retrospective study was completed for 22-revision acetabular components, using the cementless hemispherical porous coated prosthesis and minimal femoral head allograft. There was an average follow up of 48 months, with a range of 24 to 84 months. Radiographic measurements were performed in several aspects; cup-allograft contact, inclination, vertical and horizontal migration of acetabular cup, and acetabular zone by modified zone of DeLee and Charnley, in which location, size and progression or non-progression of radiolucent zone were recorded. The acetabular deficiencies were classified by the American Academy of Orthopaedic Surgeons Committee and were type I in 2 hips (9%), type II in 12 hips (55%), and type III in 8 hips (36%). Twenty acetabular cup cases of Harris-Galante II were used in this study, 1 case of Harris- Galante I, and 1 case of Duraloc. The average size of the cup was 57(44-66) mm. RESULTS: The average cup-allograft contact was 72.5% in 19 cases and we could not differentiate the margin between the host bone and the allograft in 3 cases. There was no significant vertical or horizontal migration of acetabular cup. Radiolucent zones in follow-up radiographs were 8 cases in zone IA, 4 cases in zone IB, 4 cases in zone IIB, 9 cases in zone IIC, 8 cases in zone IIIA, and 7 cases in zone IIIB. One case showed 2 mm radiolucent area in zone IIC and another case showed 3 mm radiolucent area in zone IIB, but the radiolucencies were not progressive. The remaining cases showed less than 0.5 mm radiolucent area or no radiolucent zone. The average period of bony incorporation was 13.1 months. CONCLUSIONS: We suppose that acetabular revision with the cementless hemispherical porous coated cup supported by viable host bone and minimal bone graft produces good results.

Twenty cases of pulmonary metastases from pathologically proven stomach carcinoma were studies with specialreference to the clinico-radiological findings and the grades of cell-differentiation of stomach carcinoma. Theywere calssifed into five types based on the pattern of chest X-ray findings according to the reportedclassifications of metastatic pulmonary carcinoma. The radiological appearance of pulmoanry metastases formstomach carcinoma was didffferent from that of usual pulmonary metastatic cancers. The Type IV metastatic form(Type IV-Progressive increasing interstitial lung markings and then infiltration of pulmonary parenchyme with orwithout evidence of pleural effusion.) was most commonly seen in stomach carcinoma particularly in poorlydifferentiated cell type and more associates with respiratory symptoms than others.

Incidence of aseptic loosening of hip prostheses is increasing in recent years. Previous studies suggested the involvement of proteinases and cytokines in the accelerated bone lysis associated with loosening. To investigate the role of matrix metalloproteinases (MMPs) in the loosening, Gelatin/Type IV collagenases, namely, 72 KDa matrix metalloproteinase (MMP)-2 type and 92 KDa MMP-9 type were analyzed in 14 cases of the loosened endoprostheses of the hip. Zymographic and densitometric analyses revealed production of MMP-2 ancl elevated induction of MMP-9 in tissue extracts from both the interface hetween hone and implants and the capsular tissues when compared with those in synovium obtained from a patient with a t'ractured femoral neck. MMP-9 showed stronger activity than MMP-2. In the sample of a fractured femoral neck, MMP-2 was detected, but MMP-9 was not detected. In matched samples, the activity of MMP-2 and MMP-9 in the interface tissues showed stronger activity than those in the capsular tissues. There was no difference between cemented and uncemented femoral prostheses. The state of prostheses(loosening, osteolysis, and cup wear) did not influence on the activity of MMP-2 and MMP-9. Theses findings suggest a role for MMP-2 and MMP-9 type gelatinase/Type IV collagenases in the degradation of extracellular matrix of periprosthetic tissues, where they may cause weakening of the connective tissue hed and the loosening of total hip replacement endoprostheses. Consequently. we could confirm the role of MMP cascade in aseptic loosening of total hip prostheses. The further study ahout other types of MMP and the inhihitor of MMP will be needed.

Deposition of monosodium urate crystal in joints and periarticular soft tissue is regarded as one of the characteristics of chronic gouty arthritis. In spine, however, only nineteen cases of tophaceous deposits have been reported to date suggesting the rarity of clinical symptoms secondary to involvement of spine. Authors report a case of spinal stenosis due to hypertrophy of ligament flavum with monosodium urate deposits. The patient was 65 years of age with chronic gouty arthritis who underwent a decompressive laminectomy at L4-5. At surgery, hypertrophied ligament flavum that was covered with chalky amorphous materials was noted without any evidence of radiologic features. Microscopically, a portion of ligament flavum had been focally destoryed by amorphous material deposits that were surrounded by a thin layer of mononuclear and giant cells along with occasional sprinkling of chronic inflammatory cells and negative birefringence on polarizing microscopy.

Traumatic atlanto-occipital dislocation is usually fatal. To date, few cases have been reported in the literature because survival after traumatic atlanto-occipital dislocation is extremely rare. We present the case of a 47-year-old man with traumatic atlanto-occipital rotatory posterior dislocation combined with atlanto-axial rotatory subluxation and treated by occipito-cervical fusion using Bohlman's triple wiring technique.
