Autogenous periosteal grafts are the attractive alternative to existing barrier membrane materials since they meet the reqiurements of an ideal material. But no histological data are available on the effectiveness of periosteal membranes in the treatment of periodontal defects. The purpose of this study was to evaluate effect of autogenous periosteal graft on periodontal regeneration histologically. Calss Ⅱ furcation defects were surgically created on the second, third and the fourth premolars bilaterally in the mandibles of six mongrel dogs. The experimental sites were divided into three groups according to the treatment modalities; control group - surgical debridement only : Group Ⅰ- autogenous periosteal membrane placement after surgical debridement; Group Ⅱ- autogenous periosteal membrane placement after surgical debridement and bone grafting. The animals were sacrificed at 2, 4 and 12 weeks after periodontal surgery and the decalcified and undecalcified specimens were prepared for histological and histometrical analysis. Clinically all treated groups healed without significant problems. Under light microscope, at 2 weeks, control group showed significant apical epithelial migration and bone remodelling only below the notch area. But for the groupⅠ, Ⅱ with autogenous periosteal graft, less apical migration of epithelium appeared and large amount of osteoid tissue was showen above the notch area. Grafted periosteal membrane was indiscernable at 4 weeks, so periosteal membrane might be organized to surrounding tissues. Histometrically, at 4 and 12 weeks, all the test and control groups didn't show significant change of epithelial zone but new attachment level tended to be gained in the test groups than control group. These results suggest that autogenous periosteal grafts could be a good alternative for guided tissue regeneration.

Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.

본 실험은 삼차신경 자극으로 발생되는 체성 감각 유발 전위에 대한 국소마취제의 효과를 관찰하였다. 나트륨 통로차단을 통하여 약리작용을 나타내는 것으로 알려져 있는 리도카인를 뇌 피질에 국소 투여한 후 삼차신경의 체성 감각유발 전위의 강도및 지연시간을 측정하였다. 케타민으로 마취된 흰쥐의 대측성 구레나룻 자극후 뇌의 체성 감각영역으로부터 기록되는 유발전위를 분석한 결과, 리도카인을 뇌 피질에 국소 투여시 유발전위의 강도 및 지연시간의 감소가 나타났으며, 필드 전위의 형태는 이상성(양극성 및 음극성) 혹은 삼상성(양극성, 음극성 및 양극성)의 파형으로 나타났다. 필드 전위의 발생 부위는 뇌 피질의 중대뇌동맥의 상행지 상방영역이었다. 본 실험에서 나타난 초기 전위변동은 피질판 상층에 존재하는 신경세포의 탈분극 과정에 의하여 생성되고 후기 전위 변동은 피질판 상층에 존재하는 신경세포의 탈분극 과정에 의하여 생성되고 후기의 전위 변동은 동일 영역의 하층 신경세포에서 과분극 혹은 재분극이 발생한 결과라고 유추된다. 따라서 삼차신경계의 체성 감각 영역에서는 피질 상층및 하층의 과립성 피라미드 세포의 순차적인 활성화에 의하여 기본적인 신경 회로망이 형성되어 있으며 생리적 자극으로 유발되는 필드 전위는 이러한 신경망를 통하여 발생될 것으로 사료된다.

As of the end of 2001, even though about 89% of the population throughout the country are blessed with water service, areas of seashore, island and parts of inland are still in difficulties with drinking water. For this reason, the water resources project for stable supply by developing groundwater has been conducted since 1992, under the auspices of Ministry of Agriculture & Froestry. As of 2003, a total of 594 project areas have been completed in the Gyeongsang Province by the KARICO Gyeognam Branch. Among these, 46 samples in the Geochang area developed since 1999, were chosen for chemical analysis of groundwater developed in varieties of rock. As a result, there appears excess fluorine in the granite and gneiss in this area. Correlation analysis between rock type and groundwater chemistry show that the fluorine has high correlation with Fe and aluminum in diorite, and nitrate nitrogen in the andesite rock, while hardness, total solids and SO^(2-)_(4) have high correlations each other not only in sedimentary rocks but also in all other types of rocks. It has been known that the TDS (fluorine, hardness, total solids, and SO^(2-)_(4)) of groundwater increase with depth due to water rock interaction by increasing the amount of pumping rate at the well. However, in this study, the well depth and groundwater chemistry show little correlation in between. This may be partly due to limited number of samples used in the study with a total of 46 points suitable for drinking water. It may be thought that well distributed sampling points with more samples throughout the whole area should be collected for analysis, so as to increase reliability in the result.

3차원 영상생성 과정을 반복하는 모의비행 프로그램은 매우 방대한 계산량을 필요로 하므로 빠른 작업을 위해서는 고성능 슈퍼컴퓨터의 사용이 필수적이다. 슈퍼컴퓨터의 경우에도 하나의 프로세서를 사용하기 보다는 다수개의 프로세서를 사용하여 작업을 병렬로 수행함으로써 보다 큰 속도향상을 얻을 수 있다. 본 논문에서는 Cray Y-MP 벡터 슈퍼컴퓨터를 이용하여 3차원 영상을 생성하는 병렬 프로그램을 개발하였다. 본 논문에서 구현된 병렬 프로그램은 Cray Y-MP를 구성하는 여러개의 프로세서를 사용하므로 단일 프로세서를 사용하는 경우에 비하여 프로그램의 수행속도를 크게 향상시키게 되었다.

Background and Objectives : Chronic suppurative otitis media is one of the frequent diseases in otolaryngologic field. It is important to choose of antibiotics in the management of infectious disease. But the organisms in infections have been changed and resistance to antibiotics has been grown as the development of antibiotics has been achieved. And so it has been necessary to recognize the changes of organisms and resistance in antibiotics. Our study was performed to identify the pathogens isolated from discharges in chronic otitis media and evaluate the antibiotic agents, to recognize the change of to resistance to·antibiotic agents and to use the appropriate anitiotics. Materials and Methods : Retrospectively, authors reviewed the backeriologic study of 114 cases of chronic suppurative otitis media who visited the Department of Otolaryngology, Soonchunhyang University in Seoul from Nov. 1996 to Oct. 1999 and analyzed 101 strains and its sensitivity test to various antibiotics. Result : In 93 cases in which pathogenic organism was isolated, single infection was 85 cases(91.4%) and mixed infection was 8 cases(8.6%). The most frequent pathogenic organism was Staphylococcus aureus(59.4%), Pseudomonas aeruginosa(13.9%), Providencia(4.8%), Alcaligenes(3.0%) and Streptococcus pneumoniae(2.9%) were the next. Methicilline-Resistance Staphylococcus aureus was 34 cases(57.6%) of Staphylococcus aureus. Staphylococcus aureus was sensitive to Vancomycin(96.7%), Trimethoprim-Sulfamethoxazole (57.6%), Cefuroxime(42.4%) and Ciprofloxacin(40.7%) but resistant to Penicillin(94.9%). Pseudomonas aeruginosa was sentitive Amikacin(100%), Ciprofloxacin(100%) and Gentamicin(67%). Conclusion : As MRSA recently was wide spread in community accquired infection as well as nosocomial infection, we must consider strict control of MRSA.
