Procedures for treatment of molar furcation invasion defects range from open flap debridement, apically repositioned flap surgery, hemisection, tunneling or extraction, to regenerative therapies using bone grafting or guided tissue regenerative therapy, or a combination of both. Several clinical evaluations using regenerative techniques have reported the potential for osseous repair of treated furcation invasions. Regenerative treatment of maxillary molars are more difficult due to the multiple root anatomy and multiple furcation entrances therefore, purpose of this study was to evaluated histologically compomer and Ketac Silver as a barrier in the treatment of a bi-furcated maxillary premolar. Five adult beagle dogs were used in this experiment. With intrasulcular and crestal incision, mucoperiostcal flap was elevated. Following decortication with 1/2 high speed round bur, furcation defect was made on maxillary premolar. 2 month later one premolar was filled with compomer and the other premolar was filled with Ketac Silver. After 4, 8 weeks, the animals were sacrificed by vascular perfusion. Tissue block was excised including the tooth and prepared for light microscope with H-E staining. Results were as follows. 1. Compomer & Ketac Silver restoration were encapsulated fine connective tissue. 2. In 4 weeks, compomer & Ketac Silver restoration slightly infiltrated inflammatory cells but not disturb the new bone or new cementum formation. 3. In 8 weeks, compomer & Ketac Silver restoration were less infiltrated iflammatory cell and encapsulated fine connective tissue. 4. Therefore, compomer & Ketac Silver filling to the grade III maxillary furcations with multiple root anatomy and multiple furcation entrances is possible clinical method and this technique is useful method for maxillary furcation involvement but it is thought that periodic maintenance should be needed

본 연구는 일부 지역 대학생들을 대상으로 담배가격 인상에 따른 금연의지 및 관련요인을 파악하고자, 전라북도내 위치한 2개 종합대학 809명의 학생들을 대상으로 2004년 9월 15일부터 10월 10일까지 구조화된 설문지를 이용하여 조사를 실시한 결과는 다음과 같았다. 흡연율은 남성 24.5%, 여성 1.3%이었으며, 흡연자 109명의 79.8%가 담배가격이 인상되면 금연을 시도할 의지가 있는 것으로 조사되었다. 로지스틱 회귀분석 결과 운동을 1주에 3회 이상 실시하는 경우 (OR=3.22, 95% CI 1.05, 9.81)와 현재 금연을 고려하고 있는 경우(OR=7.10, 95% CI 2.35, 21.43) 담배가격 인상이 따른 금연계획에 실제 영향을 주는 것으로 조사되었다. 이상의 결과 운동과 현재 금연계획 여부만이 여향을 미치는 것으로 조사되어, 금연의지 여부에 영향을 주는 것은 담배 가격인상에 대한 경제적 부담이라기보다 평소 금연을 할 의지와 건강에 대한 개인의 가치인 것으로 생각된다. Objective : The purpose of this study was to investigate the associated factors between raising of tobacco price and willingness to quit smoking among university students. Methods : Total 809 students in an Jeollabuk-do`s two universities participated in this study. During the period from Sep 16, 2004 to Oct 10, they was answered the structural questionnaire on smoking, exercise and drinking status and sociopsychological factors. Results : The smoking rate of men was 24.5% and women 1.3%. The 87(79.8%) of 109 smokers would quit smoking if price of tobacco raised, and the factors that affects cessation of smoking was major, execise, allowance, opinion for raising the price of cigarette, self efficacy and current plan to quit smoking. But, exercise more than 3 times a week(OR=3.22, 95% confidence interval 1.05, 9.81) and current plan to quit smoking(OR=7.10, 95% confidence interval 2.35, 21.43) were closely associated with willingness to quit smoking by multivariate logistic regression. Conclusions : The major factors affecting the willingness to quit smoking were not economical burden but current willingness to quit and personal values of health.

Objective: This study was conducted to quantify the health risk of volatile organic compounds (toluene, xylene) in toluene workers exposure from various media (i.e. working environment, indoor, outdoor, and in car). Methods : Data were obtained from Korean Industrial Health Association, the Ministry of Environment, and other researchers. The VOCs concentration was calculated from various media, and Monte-Carlo simulation was performed for uncertainty analysis of exposure assessment. Results: Total VOCs exposure of workers was estimated as follows : toluene, 0.077 ± 0.17 mg/m3/day, and xylenes, 0.096 ± 0.12 mg/m3/day. And total hazard index was estimated as 1.15 ± 1.16. Conclusions: This study suggested that occurrence of hazardous impact through lifetime VOCs exposure would be expected in toluene workers, and that the Monte-Carlo simulation as useful in the fields of occupational health.

Korean hemarrhagic fever may be accompanied with complication of hemorrhage which may occur at any organ. In the autopsy findinge of Korean hemorrhagic fever patients, coagulation necrosis of anterior pituitary gland is known as one of the most characteristic macroscopic finding and shows in almost all patients but there has been rare reporte of panhypopituitaryem in patients with Korean hemorrhagic fever. Recently we have experienced panhypopituitarysm in one patients. He was admitted to our hospital under the impression of Korean hemorrhagic fever and managed including hemodialysis therefore he was in recovery phase, but from 30th admission day, the symptom and sign were developed, suited hypopituitarysm. The patient was confirmed as panhypopituitarysm by combined anterior pituitary function test there was no evidence of hypothalamic or pituitary dseases by several test including brain CT scan. Korean hemorrhagic fever was confirmed by the high titers of antibody against Hantaan virus in patient serum. Our experience shows that Korean hemorrhagic fever can be a cause of panhpopituitarysm and we think that one should give attention to Korean hemorrhagic fever with atypical course and seasonal variation.

Rifampicin is a widely used drug for the treatment of mycobacterium tuberculosis infections. This drug, among others, is a potent inducer of the hepatic mixed oxygenase enzymes involved in drug metabolism. Therefore, the effects of drugs or hormones metabolized by liver enzymes may be influenced by rifampicin administration. Thus, concurrent treatment of rifampicin and the glucocorticoid hormone can lead to decreased bioavailability of the glucocorticoid hormone and to icreased requirement. With a brief review of the literature, we report a case of rifampicin-induced adrenal crisis, in which the patient received a physiologic maintenance dose of prednisolone and rifampicin.
