To investigate the tubular major histocompatibility complex(MHC) expression and inflammatory phenotypes in tubulointerstitial nephritis, Lewis rats were inununized with azobenzen-earsonate-tyrosine in complete Freund adjuvant and challenged either foot pad or kidney, either by subcapsular injection or by ex vivo perfusion. The rats were sacrificed 2, 3, 5, 10 and 15 days after antigenic challenge. Foot pad swelling was significant at the antigenic challenge site (151.8 vs 6.8 x 10(-2) mm) at 24 hours. Tubulointerstitial nephritis was induced by both methods and the inflammatory infiltrate which first appeared on day 2, became prominent at day 5, then gradually subsided in ex vivo perfused rats, while inflannnation started on day 3 in subcapsular injected rats. The major site of inflammation was in the cortex and outer stripe of the outer medulla, with predominance of mononuclear cells throughout the course. The inflammatory cells showed mainly OX8 and ED1 positivity with OX19, W3/25 and CD5 positivity in minority. RT1B expression was diffuse in the cytoplasm of proximal tubules at day 2 and 5. These results suggest the involvement of cell mediated immunity in this experimental model, and the possibility that tubular epidielial cells process antigen and then become targets in immune injury.

The pathologic and immunopathologic findings of 15 skin biopsies of Behcet's syndrome were studied to investigate the pathogenetic mechanism of this syndrome. The age range was 28 to 50 years; male to female ratio was 1 : 1.2. Ulceration with acute necrotizing and chronic nonspecific inflammation was present in most cases with leukocytoclastic vasculitis and perivascular lymphohistiocytic, plasmocytic infiltrations. Eight of 15 cases showed C3 deposit in the walls of venules and capillaries, one of them was associated with IgM and fibrinogen deposits. With these findings humoral factor seemed to play a main role in the pathogenesis of vasculitis observed in Behcet's syndrome, but the possibility of other mechanisms operative in complex pattern was also considered.

Articular cartilage can be damaged by trauma or by progressive degradation caused by disease. Unfortunately, it has a extremely limited capacity for repair and regeneration. The use of joint prosthesis has revolutionized but remains limited in its use. To know the possibility of clinical application of clinical application of autogenous bone-articular graft in open complicated intraarticular fractures we studied the change of bone-articular cartilage defect in medial femoral condyle of rabbits and viability of autogenous bone-articular graft stored within abdominal wall of rabbits. The results were obtained as follows: 1. There was over 90% viability of subchondral bone after 10 days storage in the adbominal wall but the articular cartilage showed degenerative change about 40% after 5 days passed. 2. The bone-articular defect was replaced by undifferentiated mesenchymal tissue and fibrous tissue, postoperative 6 weeks later. 3. In implanted bone-articular cartilage graft at 3 days, the chondrocyte of basal cell layer in articular cartilage was relatively well preserved but in 7 days, transplanted articular cartilage graft showed almost necrotic chage. Most of subchondral bones were well healed with host bone without regard to duration of implantation.

A 58-year-old female with an episode of gross hematuria two months before and fever and chill for the past three days presented oliguric acute renal failure. She has taken NSAID intermittently for 18 years due to rheumatoid arthritis, and herb medicine for one week two months ago when gross hematuria developed. Physical examination revealed mild tenderness on costovertebral angles. Her blood pressure was 170/100 mmHg, the urinalysis showed >300 mg protein with many RBCs and 10-20 WBCs and the serum creatinine was 5.8 mg/dl. A renal biopsy performed on the 4th hospital day showed that it was overwhelmed by severe tubular lesions which reveal intratubular obstruction by massive erythrocyte casts and tubular necrosis. The glomeruli showed focal minimal crescents with many red blood cells entrapped in the crescents and in the capillaries. Immune deposits were not present. A renal failure resolved spontaneously and the patient was discharged three weeks later with creatinine of 2.4 mg/dl. In this patient, acute renal failure was considered to be due to a tubular lesion related to the glomerular bleeding from focal glomerulonephritis revealing minimal crescents.

PURPOSE: This study was intended for the enhancement of the elderly's quality of life helping them overcome their physiological changes about aging and reinforcing their vitality. METHODS: An nonequivalent control group post-test design was used for the study. The methods to perform the abdominal respiration exercise and to blow the pan-flute were demonstrated to 31 experimental subjects and 36 control subjects. The eight-week 30 minute daily home respiration exercise recipes were prescribed to the subjects. Mobile spirometers were used to measure FVC, FEV1, FFV1 / FVC, SaO2, breathing discomfort. Daily life satisfaction scores were recorded. Music therapy accompanied the eight-week respiration program. A post-test was performed in the same manner as the pre-test. The gathered data were analysed by SPSS/WIN program. RESULTS: 1) The pulmonary function and daily life satisfaction were significantly improved in the experimental group. 2) Both the experimental and control groups did not show significant differences in SaO2. 3) The breathing discomfort was significantly reduced in the experimental group. CONCLUSION: The respiration exercise program for the elderly through the pan-flute improves the respiration activity of the elderly and enhances their daily life satisfaction scores. Therefore, this program produces effects in enhancing the quality of life for the elderly.

Soft tissue tumor is defined as a tumor occurring in voluntary muscles, fat, fibrous tissue, along with the vessels serving these tissue and peripheral nervous system. It is difficult to make a diagnosis by conventional microscopic observation because of their pleuripotentiality and similar growth characteristics. Although their morphological findings of tumors are similar to one another, their clinical courses, treatment and prognosis are different. So early, correct diagnosis and proper treatment are neccessary. The present study is aimed to evaluate a value of immunoperoxidase staining to make definite diagnosis of soft tissue tumors and its application to surgical pathology. The material consisted of 106 cases of fibrohistiocytic tumors and malignant soft tissue tumors which are morphologically similar to malignant fibrohistiocytic tumors for 5 years period lasting from 1980 to 1984 at the Department of Pathology, Yonsei University College of Medicine. After the classificationof fibrohistiocytic tumors by the Enzinger (1983), clinical finndings were reviewed and peroxidase antiperoxidase(PAP) method with alpha1-antichymotrypsin was done in 15 cases of all fibrohistiocytic tumors. Other soft tissue tumors which were difficult to differentiate from MFH by light microscopic observation were liposarcoma, rhabdomyosarcoma, fibrosarcoma and malignant schwannoma. These 21 cases of tumors including MFH were stained with PAP method for alpha1-antichymotrypsin, S-100 protein and myoglobin. Results obtained were as follows: 1) The cases on study consisted of 19 cases of malignant fibrous histiocytoma, 2 dermatofibrosarcoma protuberans, 45 fibrohistiocytic tumors and 11 other benign fibrohistiocytic tumors. 2) The male to female ratio was 1 : 1.8 in benign and intermediate group of fibrohistiocytic tumor, but 2.2 : 1 in malignant histiocytic tumor. 3) Most cases of benign fibrohistiocytic tumors were occurred in 4th and 5th decade of life. Intermediate and malignant fibrohistiocytic tumors were mostly found in late adult life and their mean age was 43.6 year. 4) The most common sites were trunk and both extrimities in benign fibrohistiocytic tumors(88.9%), but head, neck and lower extremities in MFH (78.9%). Two cases of dermatofibrosarcoma protuberans were occurred in turnk and upper extremity. 5) The PAP stain for alpha1-antichymotrypsin was done in 15 cases of 77 fibrohistiocytic tumors which included MFH, dermatofibrosarcoma protuberans, xanthoma, xanthofibroma, dermatofibroma showed variable degree of positivity to alpha1-antichymotrypsin. The positivity of alpha1-antichymotrypsin revealed no significant difference according to differentiation of the tumors, such as benign, intermediate and malignant. 6) The PAP stain for alpha1-antichymotrypsin revealed diffuse positivity in all cases of MFH and also in a case of malignant schwannoma, fibrosarcoma, liposarcoma and rhabdomyosarcoma, but myoglobin and S-100 protein were negative. In three cases of leiomyosarcoma, two of rhabdomyosarcoma and three of malignant schwannoma, alpha1-antichymotrypsin, S-100 protein and myoglobin were negative, although a few positive tumor cells were present, which may the considered as metatypci differentiation. Another possibility of this discordance was loss of antigenicity by improper procedure of paraffin embedding and poor differentiation of tumor cells. In summary, PAP method for specific tumor marker is important for proper diagnosis of soft tissue tumors, and application to surgical pathology.
