만성의 비용혈성 직접형 고빌리루빈혈증은 Rotor 증후군과 Dubin-Johnson 증후군의 특징적인 소견으로, Rotor 증후군은 드문 양성 유전성 질환이며, Dubin-Johnson 증후군과 감별을 필요로 한다. 본 저자들은 황달을 주소로 내원한 26세 남자 환자에서 고빌리루빈혈증에 대한 검사를 시행하여 담도폐쇄 소견없이 간담도 스캔상 전형적인 Rotor 증후군의 소견 즉, 강한 심장 배후방사능이 지속되면서, 간담도계의 조영은 지연 촬영에서도 관찰되지 않으며 신장으로의 배설이 계속 관찰되는 특징적인 소견과 정상 간조직 검사 결과로 Rotor 증후군으로 진단한 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Chronic nonhemolytic conjugated hyperbilirubinemia characterizes both Rotor and Dubin-Johnson syndromes. Rotor syndrome is a rare, benign familial disorder and needs to be differentiated from Dubin-Johnson syndrome. Cholescintigraphy is a simple and informative procedure for the diagnosis, which can differentiate Rotor syndrome from Dubin-Johnson syndrome. A 26-year-old man was admitted due to asymptomatic persistent jaundice. Physical examination revealed icteric sclera without hepatosplenomegaly. Laboratory findings showed increased serum bilirubin with direct bilirubinemia. Markedly decreased hepatic uptake and poor visualization of the gallbladder and biliary tract were shown in ^(99m)Tc-DISIDA scan. Histology of the liver showed no diagnostic abnormality without pigmentation. But, we report a case of Rotor syndrome that showed characteristic cholescintigraphic findings with normal urinary total coproporphyrin excretion.

This study investigated participants who have taken part in Hapkido continuously, in view of age, carrier in exercise, and gender and then analysed how these factors affect continuous participation in Hapkido. 1) The significant factors which enable the participants to continue Hapkido were revealed as health/physical fitness(71.67%), enjoyment / interrest (58.13%), self-protetio / guard(48.28%), phychological benefits(20.94%) 2) The factors of continuing Hapkido were different in ages, which showed significant differences in phychological benefits, skill fulfilment / challenge, accomplishment / position, charm, recreational activity. The response represented specifically in one or two areas in case of younger participants. The more aged, it showed relatively even distribution to the various responses due to the broaden span of thoughts. 3) The factors of continuing Hapkido were different in carrier, which showed significant differences in self-protection / grard, skill fulfillment / challenge, accomplishment/ position in different experiences in exercise. By the time of reaching first phase and second phase, it is thought to show the psychological effect of continuing exercise unconsciously in various areas. 4) The factors of continuing Hapkido were not different in gender, which implicated the fact that the overall attitude and thoughts on Hapkido of female participants and male participants are similar.

The aim of this study was to evaluate and compare observer performance between conventional radiographs and their digitized images for the detection of bone loss in the bifurcation of mandiblar first molar. One dried human mandible with minimal periodontal bone loss around the first molar was selected and serially enlarged 17 step defects were prepared in the bifurcation area. The mandible was radiographed with exposure time of 0.12, 0.20, 0.25, 0.32, 0.40, 0.64 seconds, after each successive step in the preperation and all radiographs were digitized with IBM-PC/32 bit-DX compatible, video camera (VM-S8200, Hitachi Co., Japan), arid color monitor(Multisync 3D, NEC, Japan). Sylvia Image Capture Board for the ADC(analog to digital converter) was used. The obtained results were as follows: 1. In the conventional radiographs, the mean score of the readability was higher at the condition of exposure time with 0.32 second. Also, as the size of artificial lesion was increased, the readability of radiographs was elevated (P<0.05). 2. In the digital images, the mean score of the readability was higher at the condition of exposure time with 0.40 second. Also, as the size of artificial lesion was increased, the readability of digital images was elevated(P<0.05). 3. At the same exposure time, the mean scores of readibility were mostly higher in the digitized images. As the exposure time was increased, the digital images were superior to radiographs in readability. 4. As the size of lesion was changed, the digital images were superior to radiographs in detecting small lesion. 5. The coefficient of variation of mean score has no significant difference between digital images and radiographs.

Background: The diabetic patients are at significantly increased risk of developing vascular disease. It's etiology may involve oxidative damage by free radiacals and protection againse such damage can be offered by antioxidants. We investigated that oxidative stress as assessed by measurement of total antioxidant status may play a role in development of diabetes mellitus. Method: We measured total antioxiant status using merchandised kit, glycated hemeglobin(HbA1c) in 46 type 2 diabetes mellitus patients and 50 healthy matched control subjects. Result: The total antioxidant status(TAS) was 2.10(±0.04) mmol/L in uncontrolled type 2 DM patients, 2.60(±0.03) in controlled type 2 DM patients and 2.70(±0.16) in healthy control subjects. TAS was significantly lower(P<0.05) in uncontrolled type 2 DM patients, but no significant association between in controlled type 2 DM patients and healthy control subjects. The TAS was 2.00(±0.17) mmol/L in complicated type 2 DM patients and 2.10(±0.29) uncomplicated type 2 DM patients. There was no significant associations between complicated type 2 DM patients and uncomplicated type 2 DM patients. Conclusion: Poor glycemic control is associated with reduced TAS in type 2 DM patients. TAS was thought indirect index that predict glycemic control of type 2 DM patients.

Purpose : To observe and evaluate the effects of Simvastatin-induced osteogenesis on the wound healing of defective bone. Materials and Methods : 64 defective bones were created in the parietal bone of 32 New Zealand White rabbits. The defects were grafted with collagen matrix carriers mixed with Simvastatin solution in the experimental group of 16 rabbits and with collagen matrix carriers mixed with water in the controlled group. The rabbits were terminated at an interval of 3, 5, 7, and 9 days, 2, 4, 6, and 8 weeks after the formation of defective bone. The wound healing was evaluated by soft X-ray radiography. The tissues within defective bones were evaluated through the analysis of flow cytometry for the manifestation of Runx2 and Osteocalcin, and observed histopathologically by using H-E stain and Masson’s trichrome stain. Results : 1. In the experimental group, flow cytometry revealed more manifestation of Runx2 at 5, 7, and 9 days and Osteocalcin at 2 weeks than in the controlled groups, but there was few difference in comparison with the controlled group. 2. In the experimental group, flow cytometry revealed considerably more cells and erythrocytes at 5, 7, and 9 days in comparison with the controlled group. 3. In the experimental group, soft x-ray radiography revealed the extended formation of trabeculation at 2, 4, 6, and 8 weeks. 4. Histopathological features of the experimental group showed more fibroblasts and newly formed vessels at 5 and 7 days, and the formation of osteoid tissues at 9 days, and the newly formed trabeculations at 4 and 6 weeks. Conclusion : As the induced osteogenesis by Simvastatin, there was few contrast of the manifestation between Runx2 and Osteocalcin based on the differentiation of osteoblasts. But it was considered that the more formation of cells and erythrocytes depending on newly formed vessels in the experimental group obviously had an effect on the bone regeneration.
