Background: This study was conducted to compare the accuracy of computered tomography(CT) and sonography(US) in diagnosing acute appendicitis and to analyze the radiologic factors which influence the result. Methods: We retrospectively studied the cases of 53 patients who were suspected of having appendicitis and who were examined by CT and US covered a three-year period. The final diagnosis was determined from the surgico-pathologic diagnosis and clinical follow-up for two months, as well as from the discharge diagnosis. Results: Thirty-eight(38) patients had acute appendicitis; 15 patients did not. In the analysis, CT and US, respectively, revealed sensitivities of 89.5% and 73.7%, specificities of 93.3% and 60.0%, positive predictive values of 97.1% and 82.4%, negative predictive values of 77.8% and 47.4%. Among patients diagnosed with acute appendicitis, 10 patients were discordant in the US and the CT examinations; CT findings were correct in 8 and US findings in 2. Among non-appendicitis patients, 5 patients were discordant in the US and the CT examinations; CT was correct in 5 and US in 0. Nighteen(19) patients had complications such as an abscess or a perforation. Among these patients, the degree and the extent of the complication were accurately evaluated by CT in 15 patients and by US in 5 patients. Conclusion: CT is more accurate than US in diagnosing and excluding acute appendicitis. The use of CT will substantially decrease unnecessary laparotomies and post-operation complications.

배지현,김영균,윤필영,조병훈,최용훈 大韓齒科保存學會 2010 Restorative Dentistry & Endodontics Vol.35 No.1
본 연구에서는 인위적으로 노출시킨 비글견의 치수조직을 기존의 수산화칼슘제재와 MTA, 접착성 레진, 광중합형 수산화칼슘제재를 사용하여 직접치수복조한 후 각 재료에 따른 치수의 반응을 광학현미경 하에서 조직학적으로 관찰하여 비교분석하였다. 2마리 비글견의 36개 치아를 이용하여, 실험적으로 치수를 노출시키고 노출된 치수에 치수복조재를 적용한 후 와동은 복합레진으로 충전하여 직접치수복조술을 시행하였다: (1) Mineral Trioxide Aggregate (MTA: ProRoot MTA, Dentsply, Tulsa, USA), (2) Clearfil SE Bond (Dentin adhesive system: Kuraray, Osaka, Japan), (3) Ultra-Blend (Photopolymerized Calcium hydroxide: Ultradent, South Jordan, USA), (4) Dycal (Quick setting Calcium hydroxide: LD Caulk Co., Milford, USA). 희생전 90일, 30일, 7일 전에 각 복조재별로 3개씩의 와동을 충전하였고 비글견을 희생시키고 조직시편을 제작하였다. 시편을 H&E 염색 후 광학 현미경으로 치수염증반응과 경조직 형성 정도를 관찰하였다. MTA 군은 초기에는 경조직 형성이 관찰되지 않고 치수조직의 위축과 부분괴사가 관찰되었으나 시간이 지나면서 경조직 형성이 관찰되었다. Clearfil SE Bond군은 초기에 염증세포의 침윤과 치수세포의 괴사를 관찰할 수 있었고 시간이 지날수록 치수 세포의 괴사가 더욱 진행한 양상을 보였다. Ultra-blend 군과 Dycal 군은 MTA 군과 비슷하게 초기에는 경조직 형성을 보이지 않고 중등도의 염증반응이 관찰되었으며 시간이 지나면서 경조직 형성이 관찰되었다. MTA, 수산화칼슘제재와 광중합 수산화칼슘제재는 초기의 치수염증반응 이후 조상아세포층, 상아질교 형성을 보여 직접치수복조재로 적당하였으며, 접착성 레진은 심한 염증반응과 치수 조직의 괴사 양상을 보여 직접치수복조재로 부적당하다는 결론을 얻을 수 있었다. The purpose of this study was to evaluate the pulp tissue reaction to direct pulp capping of mechanically exposed beagle dogs' pulp with several capping materials. A total of 36 teeth of 2 healthy beagle dongs were used. The mechanically exposed pulps were capped with one of the followings: (1) Mineral Trioxide Aggregate (MTA: ProRoot MTA. Dentsply, Tulsa, USA), (2) Clearfil SE Bond (Dentin adhesive system: Kuraray, Osaka, Japan), (3) Ultra-Blend (Photo-polymerized Calcium hydroxide: Ultradent, South Jordan, USA), (4) Dycal (Quick setting Calcium hydroxide: LD Caulk Co., Milford, USA) at 7, 30, and 90 days before sacrificing. The cavities were restored with Z350 flowable composite resin (3M ESPE, St. Paul. MN, USA). After the beagle dogs were sacrificed, the extracted teeth were fixed, decalcified, prepared for histological examination and stained with HE stain. The pulpal tissue responses to direct pulp capping materials were assessed. In MTA calcium hydroxide, and photo-polymerized calcium hydroxide groups, initial mild inflammatory cell infiltration, newly formed odontoblast-like cell layer and hard tissue bridge formation were observed. Compared with dentin adhesive system, these materials were biocompatible and good for pulp tissue regeneration. In dentin adhesive system group, severe inflammatory cell infiltration, pulp tissue degeneration and pulp tissue necrosis were observed. It seemed evident that application of dentin adhesive system in direct pulp capping of beagle dog teeth cannot lead to acceptable repair of the pulp tissue with dentine bridge formation.

연구배경 : 노인의 인지장애는 노인성 치매로 잘 알려진 알쯔하이머병의 기능적 상태가 감소한 경우와 연관이 많다. 그러나 이러한 인지장애가 기타 신체적, 정신적, 사회적 및 가족적 문제와 어느 정도까지 병존하고 있는지는 아직도 많이 알려져 있지 않은 편이다. 이 연구의 목적은 흔한 노인성 조건들, 가족기능, 그리고 영양학적 문제들이 기능적 의존성과 독립적으로 연관되어 있는지를 알아보기 위하여 시행되었다. 방법 : 1997년도 12월부터 1998년도 6월까지 우리나라의 9개 종합병원 및 대학병원 가정의학과, 신경과 및 노인병클리닉에 내원하거나 입원한 53명의 알쯔하이머병 환자들이 대상이 되었다. 모든 환자들은 치매에 관한 DSM-IV 진단기준 및 NINCDS-ADRDA 기준상 probable Alzheimer's disease에 부합하였으며, 모두 경도 내지 중등도의 인지장애를 보였고, 언어소통이 가능하였다. 종속변수는 기본적 일상생활활동 (Basic Activities of Daily Living, BADLs) 및 도구적 일상생활활동 (Instrumental Activities of Daily Living, IADLs) 이었고, 주요 독립변수에는 정신상태, 우울, 흔한 노인성 조건들 19가지, 가족기능, 영양상태 등이 포함되었다. 기술통계학과 사회인구학적 및 건강변수들과 같은 혼란변수를 통제하기 위하여 다변량분석을 사용하였다. 결과 : 알쯔하이머병 환자들의 56%가 하나 이상의 ADLs 의존성을 보였으며, 그중 목욕하기 (55%), 옷입기 (47%) 등에서 어려움을 보였으며, IADLs 의존성중에서는 여행 (79%), 집안일 (79%), 재정관리 (79%) 등에서 의존성이 높았다. 알쯔하이머병 환자들에 영향을 미치는 일부노인성 조건들, 그중 특히 피로, 요실금, 구갈, 수면장애, 낙상력, 눈의 통증, 어지러움, 슬관절통, 체중감소, 요통 등의 경우 IADLs 의존성과 다발성 연관관계를 보였고, 낮은 교육수준, 요실금 등은 ADLs 의존성과 관련이 깊은 것으로 나타났다. 이러한 결과들은 ADLs, IADLs 개개항의 의존성, 조건들이 독립적인 예측인자가 될 수 있으므로 그에 대한 의학적 가료를 요할 것을 의미하며, 하나의 조건을 예방하는 것으로는 그 이상의 IADLs 의존성을 방지하는데 충분하지 못하다는 것이다. 즉, 여러 가지 활동의 의존성 및 조건들이 개개인의 결과변수에 독립적으로 관련하기 때문에 그들의 기능적 의존성 이 예견된다면 이러한 다발성 조건들은 동시에 치료하여야 할 필요가 있다고 할 수 있겠다. 결론 : 알쯔하이머병의 기능적 의존성과 흔한 노인성 조건들에 대하여 조사한 결과, 일부 조건들이 알쯔하이머병의 기능적 상태에 미치는 효과를 최소화하기 위한 노력이 개개인에 맞게 이루어져야 하고, 다발성 질환들을 다스려야 할 필요가 있다는 것이다. 알쯔하이머병에 대한 성공적인 평가 및 치료는 환자의 개개 의학적 조건들의 기능적 상태에 독립적으로 기여하는가에 대해 사려깊게 짚어보아야 할 것이다. 그 개연성의 문제에 대하여서는 알쯔하이머병에 대한 종적 및 기타 실험적 자료들이 계속 나와야 할 것이다. Background : The purpose of this study was to determine whether common geriatric conditions, family function, and nutritional problems had an independent association with functional dependence beyond the effect of cognitive impairment in 53 patients with Alzheimer's diseases. Methods : The ample for this study consisted of 53 in-patients and out-patients of nine hospitals in Korea. All subjects met DSM-IV criteria for dementia and NINCDS-ADRDA criteria for probable Alzheimer's disease. Among fifty-three patients with probable Alzheimer's disease, all were mildly to moderately impaired and communicable. Chi-square tests were performed to assess bivariate relationships between the selected social and demographic factors, common geriatric conditions, nutritional status, and functional status. Multivariate analyses were done using logistic regression models to adjust for the potentially co nfounding effects of sociodemographic and health variables. Results : 56.6% of the study population was dependent on one or more items in ADLs. The most prevalent items of ADL dependence were bathing (54.7%) and dressing (47.2%). Subjects with lower education level, poor cognition, and poor nutrition were more likely to be dependent. Low educational level, poor cognition, and urinary incontinence were associated with the increased risk of ADL dependence. Several conditions are independently associated with the specific items of IADLs. Each item of IADL dependence of the patient has its own set of independent predictors. Some conditions are more universal in independently predicting IADL dependence. Conclusion : It was found that some common geriatric conditions affecting patients with Alzheimer's diseases appear to have multiple and differential relationships with the specific instrumental activities of daily living (IADLs) dependences. These results have implications for medical care. Preventing one condition may not be sufficient to prevent future IADL dependences since in most cases more than one condition is independently related to each outcome variable. Thus, multiple conditions may need to be managed concurrently if further functional dependence is to be expected.

조덕봉,김동필,최춘순 광주보건대학 1981 論文集 Vol.6 No.-
Dehydration phenomena has been studied for the shiitake mushroom Lentinus edodes sanryun No. 1, through which examine the effect of temperature and air velocity and derivation of its kinetics. Temperature effect for the dehydration rate constant were examined under the constant air velocity (1.5m/sec) with the variation of temperature from 40℃ to 55℃. Water content were reduced exponentially with the course of time and calculated dehydration rate constant values varies with temperature with an Arrhenius-type relationship, which had been expected in the chemical reaction kinetics. Influence of air velocity for the dehydration rate constant under the constant temperature (45℃) showed interesting results. For the range 1.0m/sec to 2.0m/sec, dehydration rate constant values are increased with the air velocity, but for the 2.0 to 3.1m/sec, dehydration rate constant values are ddecreased which were caused by case hardening. One of the selected conditions in the optimal dehydration range, temperature 50℃ air velocity 2m/sec, and its measured humidity 38~41%, mathematical model of dehydration curve and dehydration rate equations were developed and the resulting kinetic models were, X=6.94e^(-0.345t) and dX/dt=-2.39 e^(-0.345t).
