1.Expression of Fragile Histidine Triad (FHIT) Gene Product in the Uterine Cervical Carcinoma.
Korean Journal of Gynecologic Oncology and Colposcopy 1999;10(3):217-223
To investigate the involvement of expression of the Fragile Histidine Triad(FH1T) gene product in the process of carcinogenesis and progression in cervical carcinoma, we examined its expression by immunohistochemical method in 15 cervical invasive carcinomas, 10 low grade cervical intraepithelial neoplasias(CINs) and 30 high grade CINs(CMI and III). We detected expression of FHIT gene product in 4 of 15(27%) of invasive carcinomas, 3 of 10(30%) low grade CIN and 7 of 30(23%) of high grade CIN, while we detected expression of FHIT gene product in 28 of 45(62%) normal and metaplastic epithelium near the tumor. Thesc data indicate that loss of expression of FH1T gene product has some role in the early tumorigenesis of uterine cervical carcinoma, but not the consequence of the pregression of the tumor.

3.A Study of Fluorescence Pattern of Immune Deposits in Bullous Pemphigoid and Epidermolysis Bullosa Acquisita.
Korean Journal of Dermatology 1994;32(4):626-630
Backgraund : Most of the inflammatory bullous lesions in bullous pamphigoid(BP) and epidermolysis bullosa acquisite(EBA) demonstrate similar clinical and histological features. However, the specificities of the autoantibodiea reactive to the dermo-epidermal junction antigeins are different. In these two bullouk dermat loses, there are no remarkable differences in symptomaiology, there are no unique predilection sites for the lesions and they do not usually leave scars after nvolution. Considering these similarities, dermatologists could encounter some clinical confuiion in maling a provisional diagnosis. OBJECTIVE: Authors examined three patients of BP with classic inflammatory bullous eruptions and threa patients of EBA with inflammatory bullous lesions to see if here were any differences in the morphology of the immuno-fluorescence(IF) pattern. METHODS: For direct IF of vertical or semi-vertical sections, perilasional skin was obtained in each patient for indirect IF of horizontal or semi-horizonta1 sections, Ig(bound substrates were prepared from all these autoantibody-positive individuals. All specimens veri; observed at 200/400-magnification fields through an ordinary fluorescence microscopy. RESULTS: Patterns of fluorescence observed by direct IF were characterized as thin-linear in BP and thick/coarse-linear in EBA along the basement membrane zone. On the horizontal section preparations in indirect IF, the patterns of fluorescence were clean-linear in E3P hnd more fluffy-linear in EBA at the dermoepidermal junction, These patterns could be recognized aim/larly in the fields of both 200 and 400-magnification, however each minor differences were not easy to distinguish each other. CONCLUSION: The above findings of subtle differences in the pattern of IF may provide some suggestions to the examiners for the need of differential diagnosis in theae riseases.

6.Computed tomography of pituitary apoplexy: report of 2 cases
Journal of the Korean Radiological Society 1982;18(1):45-48
Pituitary apoplexy, the sudden infarction, necrosis or hemorrhage into a pituitary adenoma may be threatening life and is difficult to diagnose. With an advent of CT, early diagnosis of hemorrhage into the pituitary adenomais possible if one has familiarity with its characteristic CT changes. Two cases of pituitary apoplexy are reported with brief review of the literatures. One case had a history of radiation therapy for pituitary adenoma 7 years ago, and the other had no symptoms or sings of pituitary tumor prior to onset of disease.

7.Giant cell tumor in long bones: The significance of marginal sclerosis for the differential diagnosis.

Journal of the Korean Radiological Society 1993;29(2):307-311
Plain radrographs of thirty nine patients with giant cell tumor of long bone and CT scans of twenty patients among the thirty patients were reviewed retrospectively to evaluate the frequency and significance of sclerosis of the tumor margin. The sclerosis of the tumor margin was observed on plain radiographs in thirteen patients(33.3%) and they were located either on epiphyseal or on both epiphyseal or metaphyseal portion of the tumor. The authors concluded that the giant cell tumor should not be excluded from the differential entities eventhough the tumor has the marginal sclerosis.

Korean Journal of Gastrointestinal Endoscopy 1993;13(1):99-110
To investigate the diagnostic accuracy of ERCP in pancreatobiliary disease, the authors analysed the 1,244 cases of ERCP. The success rate of ERCP was 91.5%. The diagnostic accuracy of ERCP was 93.6% and complications occurred in 2.1%. Complications included pancreatitis,cholangitis and drug reactions. Among the biliary tract disease diagnosed, by ERCP, biliary tract stone was the most common finding. Compared with operative diagnosis of biliary tract stones,the sensitivity of ERCP diagnosis was 92.7% while that of sonographic diagnosis was 81.4%. The specificity of ERCP diagnosis was 94.4% while that of sonagraphic diagnosis was 80.9%. ln the diagnosis of common bile duct stones, ERCP was more accurrate than sonographic diagnosis. The results show that ERCP was a safe and effective diagnostic tool in the assessment of pancreatobiliary tract disease.

The purpose of this study was to evaluate the effect of estrogen receptor on the degenerative change of articular cartilage by observation of different changes of histology, matrix glycosaminoglycan and chondrocyte proliferation. In sixty-four Newzealand rabbits, experimental instability was made to induce degenerative changes by sectioning the anterior cruciate ligament, medial collateral ligament and medial meniscus of the left knees. In the oophorectomy group (32 rabbits), knee surgery was performed at 6 weeks following bilateral oophorectomy. In the non-oophorectomy group (32 rabbits), knee surgery was performed without oophorectomy. Four rabbits were killed at 0, 1, 2, 4, 8, 12, 16, 20 weeks, respectively, after the knee operation. Total immunohistochemical scores of estrogen receptor were evaluated between the two groups. Histologic evaluation of H-E staining was conducted by alcian blue staining. Evaluation of chondrocyte proliferation was carried out by immunohistochemistry using monoclonal antibody to 5-bromo-2 -deoxyuridine. The stainability of each staining was calculated using semi-quantitative analysis and statistical differences were evaluat- ed by ANOVA test and LSD multiple comparison test. Total immunohistochemical scores of estrogen receptor in the non-oophorectomy group were higher than the oophorectomy group (P<0.05). In the non-oophorectomy group, the histologic scores and the histochemical scores of glycosaminoglycan were lower than the oophorectomy group after 4 weeks and 8 weeks respectively (P<0.05). The immunohistochemical score of BrdU was the highest at 2 week and then decreased after 4weeks in both groups. The immunohistologic scores of non-oophorectomy group was significant higher than oophorectomy group between 1 and 4 weeks (P<0.05). Our results suggested that the estrogen might aggravate the degenerative change of the knee joint in rabbits by decreasing matrix glycosaminoglycan and increasing chondrocyte proliferation.
