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.

PURPOSE: This study was performed to identify the relationship between PMS and sex role. METHOD: Data were collected from 417 female college students in Seoul and Gyeonggi-do area during the period from the 6th of September to the 15th of October in 2004. Collected data were analyzed using SPSS WIN 11.0. RESULT: The results of this study were as follows: 1) Perceived subjective symptoms were clustered endogenous depressive feature (2.76+/-.97), anxiety (2.76+/-1.09), and impulsivity (2.72+/-1.02). 2) PMS was significantly different according to the general characteristics of menarche age (F=5.910, p=.003), pain (F=7.886. p=.000) and family history (F=5.366, p=.005), masculinity was significantly different according to menarche age (F=3.174, p=.043), and femininity was significantly different according to menarche age (F=3.742, p=.025) and pain (F=3.256. p=.040). 3) Femininity and PMS were in a positive correlation with each other (r=.623. p=.000). CONCLUSION: This results showed that there is a significant correlation between PMS and sex role. For future research, it is recommended to identify major factors affecting PMS and the relationships between them and various subjects.

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.

PURPOSE: This study examined the relationship between the level of activity daily living and powerlessness of spinal cord injury patients'. METHOD: The subjects for the study consisted of 68 persons agreed above twenty below seventy had had spinal cord injury. The data were collected from November 1, 2003 to January 30, 2004. The instruments used for this study were ADL check List and Powerlessness Scale. The data were analysed by using SPSS computerlized program and included number, percentage, t-test and ANOVA, Pearson Correlation Coefficient. RESULTS: The mean of activity daily living was paraplegia 49.53+/-10.91 and tetraplegia 25.65+/-13.24. The mean of powerlessness was paraplegia 35.22+/-9.50 and tetraplegia 37.55+/-9.01. In the relationship between activity daily living and powerlessness were significant difference. CONCLUSION: in order to increase the level of activity daily living of rehabilization nurse should be helpful to provide them. Also, it could be identified that informational support was important, that is, the lesser the informational support, spinal cord injury patient don't feel the powerlessness.

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.

We present 9 cases of plexiform schwannoma examined at Severance hospital from January, 1980 to September, 1987. The predilection sites of plexiform schwannoma included head and neck including oral cavity. The mean age at the time of diagnosis was 32 years. The difference of sex ratio was not apparent. Histopathological findings revealed multiple round to oval nodules encapsulated by thin fibroconnective tissue with nuclear palisading and Verocay body in each nodule. There was mild to moderate cellular atypia in some area, but mitotic figure was not found. The Bielschowsky's silver stain did not demonstrate any axon within or outside of the nodule. The thin capsule was positive with reticulin stain.

To know the correlation between glomerular and tubulointerstitial lesion and to define the characteristics of interstitial inflammatory cell in IgA nephropathy and classified according to WHO classification and graded tubulointerstitial lesion as mild, moderate and severe. Paraffin-embedded 5u sections were stained with UCHL-l, L26 and CD68 antibodies. More than 20 fields were examined in each case under the high power microscopy and the number of positive cells were counted. There was positive correlation between the severity of glomerular and that of tubulointerstitial lesion. The mostcommoninflammatory cells in the interstitiuin were UCHL-l positive cells followed by CD68 and L26 positive cells. As the WHO grade or tubulointerstitial lesion increased, the numbers of positive cells were increased in all three groups. The proportion of UCHL-1 Positive cells were increased in cases with high WHO grade whereas that of L26 positive cells incases with severe tubulointerstitial lesion Proteinuria was correlated with the degree of inflammatory cell infiltration, especially with that of L26 positive cells.

Colonization of mammary cancers by melanocytes with heavy pigmentation of cancer cells by melanin can occur very rarely. It is not certain which mechanism operates to achieve this transfer. However, the melanocytes might inject melanin through their dendritic processes or alternatively, the cancer cells phagocytose the terminal parts of the dendritic processes with subsequent dispersal of the contained melanin contained melanin granules. We report a case of infiltrating ductal carcinoma of breast with melanocyte colonization and pigmentation in a 59-year old female.
