To evaluate the utility of gene rearrangement analysis, eight cases of malignant lymphoma, one case of Hodgkin's disease, two cases of angioiminunoblastic lymphadenopathy (AILD) and two cases of non-specific lymphadenitis were studied by immunohistochemical and genetic analysis. Southern blot analysis was perfon-ned by a using vacuum transfer system and a biotin labelled probe. This method was faster, safer, and more convenient than conventional methods. Gene rearrangement study showed rearranged novel bands in five of six cases of B cell lymphoma, in all cases of T cell lymphoma, and in all cases of AILD. No rearrangement of the B cell receptor(BCR) or of the T cell receptor(TCR) was seen in Hodgkin's disease or in nonspecific lymphadenitis. These results suggest that gene rearrangement analysis of BCR and TCR is a recommended method for the diagnosis of clonality in lymphoproliferative disorders. It would allow pathologists to differentiate lymphoma from polyclonal lymphoid proliferation and to provide information for cell lineage.

The posterior cruciate ligament(PCL) is one of the most important structures in the knee joing because it provides about 94% of the total restraint to posterior displacement of the tibia & posterior stability of the knee joint. If the posterior instability persisted, rotational instability, injury to meniscus and degenerative change develop within several years. The purpose of this study is to know the result of the posterior cruciate ligament reconstruction using semitendinosus tendon and to know the factors which affected to good result. During the period from January 1989 to December 1994, 16 cases with posterior cruciate ligament reconstruction using semitendinosus tendon were evaluated clinical and radiological results retrospectively and performed stastical analysis using the SPSS. The results were as follows; 1. The average preoperative posterior laxity was 14.1 mm and average postoperative laxity was 6.3 mm. It was improved 7.8 mm. 2. In other associated injured ligament group with or without fracture, above good was in 8 cases and below fair in 6 cases, but there was no significant difference between the two (X²=9.8, df=1, P>0.05). 3. In the poor result group, mean body weight was 80(±13.23)kg and there was significant difference between poor group & fair, good, excellent group(F=3.52, P < 0.05). From these results it would be suggested that PCL reconstruction using semitendinosus tendon is more effective in relatively light weighted group than heavier group.

Using immunohistochemical methods, the authors investigated the distribution of tubulin in normal skin and 31 skin tumors, including 11 benign skin tumors and 20 malignant skin tumors, In normal skin, tubulin was strongly expressed in basal cells of the epidermis, sebaceus celis and dermal nerves. Myoepithelial cells, ductalI cells of sveat ducts and outer root sheath cells of hair follicles stained moderat,ely. Lermal fi broblasts showed no staining. In benign tumors including keratoacanthoma, trichoepithelioma, and nevocellular nevus the strornal fibroblast.s were entirely tubulin negative as well as the turnor cells. In basal cell carcinoma, the stromal fibroblasts were negative',whereas tumor cells were weakly positive. In squarnous cell carcinoma(SCC), tumor cells weri, tubulin positive weakly, the degree of tubulin expression of its stroma1 fibroblasts tencied to be in proportional to the grade of malignanr.u. Tumor cells of malignant melanoma and nevocellular nevus were tubulin positive moderately bist the stromal fibrobla.sts were strongly positive only in the cases of malignant melanoma. These results show that the degree of the tubulin; expression in adjacent, stromal cells of epidermal tumors is in proportiona.l to that of their malignancy, These suggest that the expression of tubulin in fibroblasts surrounding tumor cells of malignant melanoma and SCC reflects a stromal alt,eration that might contribute to tumor in vasion, and play a role for cellular motility.

OBJECTIVES: The most often perfomed major operation in gynecology is hysterectomy.Our purpose was to compare the indications, charateristics and outcomes of patients undergoing total abdominal hysterectomy and total vaginal hysterectomy and to help to establish guidelines to determine the route of hysterectomy. METHOD: The hospital charts of 400 women who underwent elective inpatient hysterectomy at Kyung-Hee University hospital from January 1994 to January 1999, were abstracted retrospectively. Data were collected regarding patients, age, parity, preoperative indications, the route of hysterectomy, uterine weight, operative and postoperative complications and the length of stay. The operative indications were benign uterine disease except from uterine prolapse. Bisection or combined morcellation were used in most cases to obtain reduction in uterine size. RESULT: Patients in whom the vaginal route was successful included 18% of those with uterine weights exceeding 280gm. There was statistically significant difference for uterine weight, operative time, bleeding amount, the length of stay in two camparative group. 4% of vaginal hysterectomy and 7% of total abdominal hysterectomy has documented operative complications. CONCLUSIONS: Vaginal hysterectomy is safe operation with few intraoperative and postoperative complications without notable blood loss. Vaginal hysterectomy allow one to shorten the operating time and allows early postoperative discharge of some patients from hospital. Skilled performance of vaginal hysterectomy is worth greater attention and should be used more often in gynecological study.

Previous observations have demonstrated that fibronectia (FN) is deposited high abundance in basal cell carcinoma (BCC) stroma. Since FN is a glycoprotein which promotes interaction between cells and extracellular matrix, it may been important component of slowly expansile carcinoma such as BCC. Furthermore, BCCs aggressiveness varies with it's histologic appearance. The authors investigated distribution of plasma FN (pFN) in 8 BCC cases with various histologic types (3 nodulocystic type, 2 infiltrative type, 2 keracotic type, 1 adenoid type) and 4 squamous cell carcinomas (SCC), which have a more aggrcisive biologic behavior than BCC using immunohistochemical staining. In normal skin, pFN was strongly positive at the clenzoepidermal junction and perivascular area with a linear pattern, and in the papillary dermis with a reticular pattern, and was weakly positive in the reticular dermis. In BCC, pFN was strongly positive in nodulocystic BCC, with the highest concentration along the periphery of the tumor island in a filamentous pattern, .hereas, it was moderately positive in adenoid, keratotic, infiltrative BCC stroma. In SCC, pFN was weakly positive around tumor the margins with a thin, coarse deposition These results show that with epidermal tumors, the degree of the pFN expression in stroma is propotional to their aggressiveness.
