Statement of Problem. Objective and quantitative measurement of implant stability is very important from implant installation to long-lasting maintenance period thereafter. Purpose of study. This study was to evaluate and compare two ISQ and PTVs on the implant stability measurements according to the increased effective implant length. Materials and Methods. Twenty self-tapping fixtures were installed in the bovine scapula and in 10 of those for group I, ISQ and PTVs were obtained in the vertical/horizontal directions according to the increased effective implant length using OsstellTM and Periotest? After stability measurement, removal torques were measured between the after installation and after thread exposure group. Results. ISQ and PTVs showed decreased and increased values according to the increased abutment length. Apart from PTVs, ISQ values were shown higher in horizontal direction to the long axis of bone in both the after installation and the after thread exposure groups. Removal torque values were shown higher in after installation group. Conclusion. From the results of this study, implant stability measurement using resonance frequency analysis was more sensitive and discriminative than PTVs measurement.

Papillary eccrine adenoma is a rare benign sweat gland neoplasm. However, it can show locally aggressive clinical course when it is incompletely removed. A case of papillary eccrine adenoma of the thigh of a 46-year-old woman is reported. Immunohistochemical studies showed that this tumor was diffusely positive for cytokeratin(CAM 5.2), and carcinoembryonic antigen, and focally positive for EMA in the luminal cells of the neoplastic ducts. S-100 protein was not stained in the luminal cells and myoepithelial cells of neoplastic ducts. Papillary eccrine adenoma appears to differentiate toward ductal structures of the eccrine sweat apparatus.

From April 1977 to August 1978, author carried out an experiment to detect the presence of trichomoniasis in soldiers. Samples were obtained from 1.293 male soldiers of in-or out-patients of an Armed Forces Medical Center. For detection of Trichomonas vaginalis, both of smear method and culture method were used, and results from two methods were compared. The results were summarized as follows: 1. Detection rate of Trichomonas vaginalis is 1.8% by smear method and 3.1% by culture method respectively. This result showed culture method is about twice as highly detective as smear method. 2. A highest infection rate was found in the 30-40 year group. 3. Most of infected persons showed symptomless, although about 30% of them complained distress such as itching sensation(10%), urethral discharge(7.5), and urinary frequency(7.5%). 4. In the microscopic examination of urine, leukocytes were increased in 65% and epithelial cells were increased in 47.5% among individuals. This result showed there might be infalmmatory changes in about half the positive cases.

BACKGROUND: Facet joint have been implicated as a source of chronic low back pain. Radiofrequency denervation has demonstrated the most solid evidence. To increase safety and efficacy of treatment, computed tomography (CT) guidance injection has been used in several disease. The purpose of this study was to evaluate the efficacy of CT-guided radiofrequency rhizotomy in the treatment of facet joint pain. METHODS: A total of 40 patients were randomized to undergo radiofrequency facet joint denervation under CT guidance or C-arm guidance. All patients were examined visual analogue scale (VAS) score before treatment, 1 month, and 3 months after treatment. RESULTS: The VAS in both groups showed significant improvement over the 1-month interval. No significant difference in the VAS score among the group was observed. CONCLUSIONS: In this study there was no significant difference between CT guidance lumbar rhizotomy and C-arm guidance lumbar rhizotomy. Therefore CT-guided radiofrequency denervation of the lumbar facet joint was a minimally invasive technique that appears effective.

A clinical observations of skin lesions was performed on 189 patients suffering from hepatitis who were admitted to the Department of Internal Medicine in Armed. Forces General Hospital. The result were as follows: 1) Cutaneous manifestations were found in 143 patients(75.7%). 2) Purpuric lesion was found in 62 patients(32. 8%), spider angioma in 57 patients(30%), palmar erythema in 40 patients(21.2%), melanosis in 37 patients(19. 6%) acne in 22 patients(11,6%), jaundice in 15 patients(7.9%) and striae distensae in 14 patients(7.4%). 3) Among rnelanosis, there were 14 patients with diffuse pigmentation, 3 patients with localized pigmentation, 14 patients with palmar crease pigmentation, 10 patients with accentuation of freckling and 11 patients with chloasma. 4)Common cutaneous manifestations in acute hepatitis were spider angioma (21. 4%), palmar erythema (21.4%) and purpuric lesion (17.9%), in chronic hepatitis, purpuric lesion(44.8%) spider angioma(37%) and melanosis(24.8%).

A clinical observation of self-inflicted lesions was made during physical examination for conscription in Choongcheongnamdo from May to July, 1980. The result were as follows: 1) The prevalence of self-inflicted lesions was 8. 1% (579/7148). 2) The number of persons with criminal history was 68(ll.7%). 3) The educational level of self-injured was lower than that of non self-injured. 4) Most frequently used tools for self-inflicted lesions were cigarette(72%), knife(19. 9%), rnatch(14.7%) and grass(12.8%) in decreasing order of frequency and only one tool was used in 438 cases(75.6%). 5) The favorite site of self injury were the left forearm(89. 5%), right forearm (19.3%) and left upper arm (5.9%) 6) The average age of first injury was 16. 5 years. 7) The complications of self injury were found in 8. 8% of self-injured and they were hypertrophic scar, keloid, pyoderma and depigmentation. Some degree of hyperpigrnentation and hypopigmentation was found in most of cases. Tattoo was accompanied in 20. 7% of self-injured.

E-cadherin (E-CD), a Ca2+ -dependent adhesion molecule, plays a major role in the maintenance of intercellular junctions in normal epithelial cells in most organs. Recently, a correlation has been observed between a loss of E-CD and increased invasiveness of neoplastic cells. In this study, E-CD expression in the breast carcinoma was investigated using monoclonal antibody, anti-E-CD by immunohistochemical method. Expression of E-CD were evaluated in 57 breast carcinomas and correlated with their tumor grade, lymph node involvement, and hormonal receptor status. Histological types included in this study were 54 invasive ductal carcinomas (IDCs) of otherwise not specified and 3 invasive lobular carcinomas. Cases of histologic grade I IDC were 6, grade II 30, and grade III 18. Of 54 IDCs 39 (72.2%) showed moderate to strong linear staining at the cell borders regardless of their histologic grade, status of lymph node metastasis, and status of hormone receptor. Staining intensity of E-CD was reduced in 54 cases (83%) of IDC when compared with that of normal or benign breast lesions (P<0.01). All seven cases of intraductal carcinoma, which were included in 54 IDCs showed one or two grade reduced expression of E-CD than that of infiltrative lesions. Three invasive lobular carcinomas showed strong (1 case), moderate (1 case), and negative reactivity (1 case). The data indicated that loss of E-CD expression is a crucial event in the development of breast carcinoma.

JL1 is a novel human thymocyte differentiation antigen, which is exclusively expressed by double positive (CD4+ CD8+) cortical thymocytes. We previously reported that the JL1 antigen was selectively expressed on the surface of acute lymphoblastic leukemia cells. T-Lymphoblastic lymphoma/acute lymphoblastic leukemia (T-LBL/ALL), the 6th prevalent lymphoma in Korea, is composed of immature neoplastic lymphoid cells and shows a rapid response to appropriate treatment. Early and precise diagnosis of LBL/ALL is crucial. Light microscopic distinction of LBL/ALL from other non-Hodgkin's lymphomas can sometimes be difficult and is aided by immunophenotypic studies. This study is designed to investigate the diagnostic utility of anti-JL1 monoclonal antibody (YG5) for LBL/ALL in formalin fixed, paraffin embedded tissue. We collected 25 cases of LBL/ALL (18 T-cell, 5 B-cell and 2 undetermined lineage) from 1993 through 1998. We confirmed the diagnosis using morphologic and immunophenotypic data. Strong JL1 expression along cell membrane was observed in 16 out of 18 T-LBL/ALL cases (89%). In 28 cases of other types of lymphomas of including 7 cases of non-T LBL/ALL and 14 cases of small round cell tumors, no JL1 expression was identified. These results show that the immunostaining for JL1 using YG5 on paraffin embedded sections can be useful for the specific diagnosis of T-LBL/ALL in routine diagnostic service.
