Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

CCA 처리재로부터 방부제 유효성분의 용제추출

김규혁,공일곤,나종범,조재성,김재진 한국목재공학회 2003 목재공학 Vol.31 No.4

본 연구는 CCA 처리재로부터 방부제 유효성분을 추출하기 위한 적정 용제를 선정하고, 선정된 용제의 최적추출조건을 평가하기 위 해 수행되었다. 추출수율과 용제의 사용 및 환경 안전성을 고려할 때, 과산화수소가 CCA유효성분을 추출하는 데 가장 적절한 용제로 선정되었다. 과산화수소를 이용한 추출 결과. 추출온도, 추출용제농도, 추출시간 간에 상호작용이 존재하였으나 추출온도와 추출용제의 농도가 높을수록, 그리고 추출시간이 연장될수록 CCA유효성분의 추출수율은 증가되었다. 경제적인 측면을 고려할 때 가능하면 낮은 농도의 추출용제를 사용하여 저온에서 추출하여야 하나, 이 경우에는 필요한 추출수율을 달성하기 위한 추출시간이 상당히 길어지기 때문에 40℃ 이상의 온도에서 추출이 바람직하며 사용할 추출용제의 농도는 추출시간을 고려하여 최종적으로 결정하여야 된다고 사료된다. This research was performed to select an appropriate agent to extract preservative components from CCA-treated wood, and then to evaluate the effect of reagent concentration, extracting temperature, and CCA-treated wood, and then to evaluate the effect of reagent concentration, extracting temperature, and extracting time on the removal of chrome, copper, and arsenic from treated wood. Hydrogen peroxide was selected as the best extracting agent when considered extraction yield as well as use and environmental safety. Its extraction yield was dependent on extracting variables (temperature, concentration, and time), and a highly significant interaction existed among variables. It should be possible to optimize extraction by manipulating these extracting variables. The results may suggest that the required temperature conditions for the reasonable removal of CCA components are at least above 40℃ because extracting time is too long at low temperature (20℃). Reagent concentrations for extracting at above 40℃ should be decided by considering the extracting time.

This study was to analyze the body and bone compositions according to exercise characteristics. 32 subjects attending universities consisted of 8 track players, 8 tennis players, 8 wrestling players, and male students. A whole body scanner (model:dual X-ray absorptiometry, LUNA) was used to measure body composition components, bone mineral content, total bone calcium, bone mineral density, Comparisons of each group's bone densitometry numerics revealed following results. First, %body fat and fat body weight were significantly lower in track players, while lean body weight was significantly higher in wrestling and track players. Second, bone mineral content was significantly higher in wrestling players arms and body and track players' leg. Third, total bone calcium was significantly higher in wrestling players. Fourth, bone mineral density was significantly higher in track, wrestling and tennis players' pelvis and wrestling players' all the other parts. In sum, endurance training like track play had positive effects on developing appropriate body composition, while wrestling characterized by heavy weight, excessive and continuous exercise, and high loading had positive effects on developing appropriate bone composition. Hence, endurance training involving high loading and dynamics would be effective sports for developing appropriate body compositions.

김규혁,김형준,나종범,김재진 한국목재공학회 2003 목재공학 Vol.31 No.1

본 연구는 라디에타소나무 제재목의 균 변색을 제거하기 위한 표백처리의 사용 가능성을 조사하기 위하여 수행하였다. 염소계 표백제인 아염소산나트륨과 차아염소산나트륨은 표백조건(약제농도, 처리온도, 처리시간)의 조절에 따라 만족할만한 변색제거 효과를 얻을 수 있었다. 비염소계 표백제인 과산화수소는 표백조건의 조절만으로는 변색제거가 불가능하였으나 규산나트륨과 수산화나트륨을 활성제로 첨가하는 경우에는 염소계 표백제보다 탁월한 변색제거 효과를 나타내었다. 그러나 활성제 첨가에 따라 재색의 녹색화 문제가 발생하였는데, 앞으로 이러한 문제점을 해결하기 위한 연구가 진행되어야 할 것이다. 또한, 앞으로 본 연구를 통해 개발된 변색제거방법의 현장 적용을 후속 연구도 필요하다고 본다. The feasibility of using bleaching treatments for removing fungal stain was evaluated on heavily stained raiadta pine sapwood. Sodium chlorite and sodium hypochlorite appeared to destain fungal discoloration by providing proper treatment conditions (chemical concentration, treatment temperature, and treatment time), while hydrogen peroxide did not remove fungal stain under the bleaching regimes evaluated. The addition of sodium silicate and sodium hydroxide in the hydrogen peroxide solution as a buffer could remove fungal discoloration completely:; however, the color of wood surface turned faint green after bleaching, thereby reducing the lightness of bleached samples. The results suggest that hydrogen peroxide bleaching could be a feasible method for removing fungal discoloration of stained radiata pine sapwood, although further research is needed to solve the problem of color change after bleaching Also, further tests under field conditions are recommended.

The purpose of the present study was to compare the changes in the maximal contraction of the masticatory muscles and the occlusal contact points before and after the orthodontic treatment of the class Ⅲ malocclusion children. The subjects were consisted of 21 children with class Ⅲ malocclusion, 17 normal occlusion children and 13 treated children. The class Ⅲ malocclusion children were treated with FR-Ⅲ. The EMG signal from the masseter and the anterior temporal muscle group was recorded by the Bioelertric Processor EM2, and the occlusal contact point was evaluated by the T-Scan system. The following results were obtained: 1. In the anterior temporal muscle activity, there was no significant difference between the normal occlusion children and the class Ⅲ malocclusion children, but the masseter muscle activity of the normal occlusion children was higher than that of the class Ⅲ malocclusion group(P<0.05). 2. There was no significant difference in the both muscle activity, but in the normal occlusion group, the activity of the masseter muscle was higher than that of the anterior temporal muscle(P<0.01). 3. In the both muscle group, there was no significant difference between the right and left side. 4. In the occlusal contact point, the normal occlusion group was more recored than the class Ⅲ malocclusion group(P<0.005). 5. After treatment the muscle activity in the both muscle grpup was significantly reduced, and the anterior temporal muscle showed greater decreasing than the masseter muscle(Ant. temporal muscle: P< 0.005, Masseter muscle: P<0.05). 6. After treatment the occlusal contact point was decreased, but not statistical difference level(P=0.059).

외상환자에서 전신성 염증 반응 증후군 (Systemic Inflammatory Response Syndrome)의 발생과 혈청 TNF-α와의 관계

김현,이강현,임종천,조준휘,오범진,황성오 大韓應急醫學會 1998 대한응급의학회지 Vol.9 No.4

Background and purpose: The systemic inflammatory response syndrome(SIRS), as defined recently by critical-care specialists, may result from various etiologies including infection, burn, or trauma. The purpose of this study was to determine whether TNF-αis associated with the development of systemic inflammatory response syndrome caused by multiple trauma. Methods: The study population consisted of 21 patients with multiple trauma presented emergency department within 2 hours after insult were enrolled in this study. Multiple blood samples were serially drawn to measure serum TNF-αlevel on admission, 12 hours, 24 hours, and every day until 5 days after injury. Serum TNF-αwas measured by ELISA ("Sandwich type"). Blood samples of fifteen volunteers were used as a reference value for serum TNF-α. Results: Serum TNF-αlevels of SIRS group were persistently elevated above reference value until 3 days after on admission. Peak serum TNF-αlevel at 12 hours after admission was higher in SIRS group than non-SIRS group(p<0.05). There was no significant correlation between injury severity score and TNF-αlevels on regression analysis, all patients with ISS higher than 16 had SIRS. No one had SIRS among patients with ISS less than 16. Conclusion: The result of this study suggests that persistent elevation of TNF-αand degree of injury severity are associated with the development of systemic inflammatory response syndrome in multiple trauma.

마우스에서 전기자극 스트레스의 면역조절 효과

김정범,박종욱,배재훈 대한생물치료정신의학회 1996 생물치료정신의학 Vol.2 No.2

전기자극 스트레스가 마우스의 면역계에 미치는 영향을 조사하기 위해 체액성과 세포성 면역반응을 조사하고, 이 면역반응 결과에 대한 면역조절 기전을 이해하기 위해 전기자극 스트레스가 사이토카인의 유전자 발현에 미치는 영향을 조사하였다. 생체내 면역반응을 평가하기 위하여 흰쥐 적혈구에 대한 특이항체생성반응은 스트레스군에서 대조군보다 항체생성반응이 감소하였다. DNFB에 대한 접촉성 과민반응 실험에서 T24는 스트레스군과 대조군 간에 차이가 없었으나 T48는 T24에 비해 스트레스군에서 증가를 보였다. Phytohemagglutinin으로 자극된 비장 단핵구의 증식에 미치는 영향을 알아보기 위해 ³H-thymidine incorporation 검사를 실시한 결과 스트레스군에서 대조군보다 세포증식반응이 증가되었다. 전기자극 스트레스에 의한 면역조절 기전을 이해하기 위하여 사이토카인의 유전자 발현을 조사한 결과 스트레스군에서 대조군에 비해 IL-2, IL-6의 유전자 발현이 억제되고 IL-1, IL-12,GM-CSF,MIF등의 유전자 발현에는 대조군과 차이가 없음을 보였다. 이상의 결과를 볼 때 전기자극 스트레스에 의해 체액성 면역반응이 저하된 현상은 면역반응 활성화와 항체 생성에 중요한 IL-2및 IL-6 유전자 발현의 억제와 연관이 있을 것으로 생각되며, 스트레스군에서 IL-2 유전자 발현의 억제에도 불구하고 mitogen에 의한 세포증식반응이 증가한 현상을 해명하기 위해서는 보다 다양한 실험조건의 적용이 필요하며 더 나아가 스트레스에 의한 동물의 행동반응 또는 신경내분비계에서 나타날 수 있는 변화들과의 연관성에 대한 계속적인 연구가 필요할 것으로 생각된다. To explore the molecular mechanisms by which electric footshock has immunomodulatory effects, the effects of electric footshock, on the humoral and cell-mediated immune responses of ICR mice and then the gene expression of cytokines in splenocytes, including interleukin-1(IL-1), IL-2, IL-6, IL-12, the migration inhibitory factor(MIF), and the granulocyte macrophage-colony stimulating factor(GM-CSF), were investigated. Mice were subjected to electric footshock for 3 days(two sessions a day, 11 footshocks a 31-min session). The humoral response was measured using ICR mice immunized with rat RBC. The cell-mediated immune response was evaluated by contact. hypersensitivity to 2,4-dinitrofluorobenzene(DNFB) and by phytohemagglutin(PHA)-stimulated splenocytes proliferation assay. In the stressed group, electric footshock suppressed significantly the anti-rat RBC antibody(P<0.05), but enhanced significantly T48 relative to T24 in contact hypersensitivity(P<0.01) and T-cell proliferation response(P<0.05) by PHA stimulation relative to the control group. The gene expression of IL-2 and IL-6 were suppressed significantly in PHA-stimulated splenocytes, but that of IL-1, IL-12, GM-CSF and MIF were not. In conclusion, suppressed IL-6 gene expression seems to account for suppressed humoral immune response. In spite of enhanced cell-mediated immune response, the result is that IL-2 gene expression was suppressed, which suggests the two putative mechanisms. Firstly, while in the stressed group production of IL-2 occurs rapidly and thereafter declines abruptly, in the control group that of IL-2 occurs slowly and thereafter declines gradually. Secondly, there may be certain detouring circuits extending the signal conduction system by IL-2 except the usual signal conduction system.
