Acute fatty liver of pregnancy (AFLP) was first described as a specific clinical entity in 1940 and thought to be universally fatal. Maternal mortality in the past approached 75 percent. However early diagnosis and prompt delivery have dramatically improved the prognosis, and maternal mortality rate is now less than 18 percent. A early diagnosis, a prompt delivery, and a intensive supportive care have improved maternal and perinatal outcome. We report a 30—year—old woman at 37 weeks gestation who have multiple complications including acute pancreatitis in AFLP. She was complicated with acute renal failure, disseminated intravascular coagulation, duodenal ulcer bleeding, spontaneous bacterial peritonitis, pulmonary edema and acute pancreatitis.

Fungus such as Candida albicans is a normal flora that is frequently found in the oral cavity, gastrointestinal tract, genitourinary tract, vaginal mucosa in a normal person. However, candida can cause opportunistic infection in an immune compromised host. Candidiasis has broad spectrum of disease from mucocutaneous infection to invasive or disseminated infection. But, it is rarely reported that candida is associaed with gastrointestinal tract disease in a healthy adult. The case of gastric ulcer associated with candida particularly in a health adult is reported with relevant literature.

백색증(albinism)이란 신체 내 melanin 합성의 부분적,혹은 완전한 결핍에 의해 일어나는 질환이다. Melanin은 신체 내에서 머리카락,눈,피부 등에 분포하기 때문에 백색증 환자는 밝은 금발이나 갈색의 머리카락과 하얀 피부,붉거나 갈색의 홍채를 갖는 특징적인 외모를 지닌다. 백색증 환자는 변이된 유전자 및 임상적 특징에 따라 크게 전신성 백색증,안성 백색증,부분적 백색증으로 나뉘며 그 밖에 많은 하위군이 존재하고 그에 따른 치료법이나 치과적 주의사항도 달라진다. 본 증례는치아의 발육지연 여부평가를 주소로 내원한정신 지체가 동반된 전신성 백색증 환아로서 치아발거 등의 관혈적 시술및 보존수복,공간유지장치 등의 치료를 통해 양호한 결과를 보였기에 이를 보고하는 바이다. Albinism is a disease caused by partial or complete failure of melanin production in the skin,hair and eyes despite the presence of normal number,structure and distribution of melanocytes. Typical aspects are white-colored skin,blonde-brown hair,blue-brown irides and a prominent red reflex. Three main categories of albinism are oculocutaneous,ocular and localized albinism,and also they are divided into many subgroups. Therefore, appropriate treatment plan and dental direction would be differentiated according to them. This case report was about oral conditions and treatment of the oculocutaneous albinism patient with mental retardation who was refered due to developmental delay of teeth and treated with teeth extraction,restoration and space maintenance etc.

This study investigated the effect of thermal treatment (blanching) conditions on the physicochemical and nutritional properties of spinach. For thermal treatments, fresh spinach was treated by three blanching methods including boiled water, steam and pan frying treatments. At the varying time intervals of treatments, pH, color, shear force, proximate composition, organic acid content, peroxidase activity and microbial counts were evaluated. The pH of all treatments tended to increase with increasing blanching time, however, no significant differences among treatments were obtained. The shear force of spinach decreased with blanching time, particularly hot water treatment showed the rapid decrease in the shear force of spinach. The lightness of spinach showed similar pattern with shear force. For proximate compositions, the highest moisture content was found in hot water treatment, while crude protein and ash were highest in steam treatment. Due to the usage oil, pan frying treatment involved in the highest lipid content. The organic acid content treatment was in the order of hot water, pan frying and steam treatment. The thermal treatments attributed to low total plate count of spinach. In addition, thermophilic bacteria, coliform, mold and yeast were not detected in all thermal treatments. Peroxidase activity was lowered by applied thermal treatments. Based on the results, the best blanching condition for spinach was found in steam treatment for 60 s where the spinach showed the minimal changes in physicochemical and nutritional properties of spinach.

환기정도에 따른 수술실용 신발 종류가 수술실 오염에 미치는 영향 : How to Choose Suitable Shoes?

Background : Various types of protective footwear have been used to minimize bacterial contamination in operating rooms. In recent years, debate has arisen concerning the need for use of such protective footwear. This study was designed to provide useful data about choosing shoes most suitable for the surgical environment. Methods : Between November, 1999 and January, 2000, we performed this experimental study by comparing effect of three types of shoes (i.e., disposable shoescover, operating room-restricted shoes, and ordinary shoes) on bacterial contamination of operating rooms equipped with two different ventilation systems (i.e., high air-change, low air-change) respectively. Data were collected during two-hour sham operations in which subjects and their activities were strictly standardized. Bacterial flora were sampled from the study area floor and air colony-counts were measured. Results : In experiments involving high air-change ventilation system, there was a significant difference of floor contamination between three types of shoes, but no difference of air contamination. Under low air-change system, there was a significant difference of both floor and air contamination between three types of shoes. Conclusion : The results show that protective footwear would be unnecessary in the operating room with high air-change ventilation system, but it is important to choose suitable shoes carefully under low air-change system. Therefore, the use of outdoor shoes can be considered under high air-change system, but it would seem sensible to apply their first use in less bloody operations at the day surgery center or out-patient department to prevent transfer of body fluid into the outside environment.

본 연구는 예방적 레진 수복술에 전통적으로 사용되던 소와열구 전색제를 대신하여, 유동성 복합 레진이 사용될 경우의 타당성을 검토하기 위해 시행되었다. 비커스 미세경도를 측정하기 위해 직경 10 mm, 높이 3 mm인 11개의 시편을 제작하여 비커스 미세경도 측정기(FM-7, FUTURE-TEC Inc., Japan)를 이용하여 압입하중 50 gf, 유지시간 15초의 조건 하에서 측정하여 각 군의 평균값을 산출하였다. 표면조도를 측정하기 위해 칫솔마모시험기(Toothbrush abrasive machine K236, Tokyo Machine Co., Japan)로 4개의 시편 표면에 200 rpm의 속도로 4000회의 칫솔질을 시행한 뒤 표면조도형상측정기(Form Tahrsurf series 2, Rank Taylor Hobson Co., England)를 이용해 표면조도를 측정하였다. α=0.05의 유의 수준에서 Kruskal-Wallis rank test와 Mann-Whitney U test를 사용하였다. 또한 주사전자현미경으로 관찰하여 각 군의 마모 양상을 비교하여 다음과 같은 결론을 얻었다. 1. 비커스 미세경도 측정 결과 Filtek Z350 flowable(3M ESPE, U.S.A), Palfique Estelite LV(Tokuyama Dental, Japan), Ultraseal XT plus(Ultradent, U.S.A) 순으로 높게 나타났으며 모든 군 간에 통계적으로 유의한 차이가 있었다(p<0.0001). 2. 표면 조도 측정 결과, Ultraseal^(R), Estelite^(R), Z350^(R) 순으로 높게 나타났으나 통계적으로 유의한 차이는 없었다(p=0.116). 3. 마모되지 않은 표면과 마모가 일어난 표면을 주사전자현미경으로 관찰한 결과, 전색제인 Ultraseal XT plus와 유동성 복합레진인 Palfique Estelite LV, 나노필러를 함유한 유동성 복합레진인 Filtek Z350 flowable이 서로 다른 마모 양상이 나타나는 것을 볼 수 있었다. 이상의 결과를 토대로 할 때, 유동성 복합 레진이 전색제에 비해 물성적 측면에서 더 우수한 것으로 나타났다. This study was performed to compare the wear resistance of sealant and flowable resins for analyzing the effect of flowable resin as a sealant in preventive resin restorations. Specimens were made and Vicker's hardness number and surface roughness were measured. SEM observations of the polished and abraded surfaces were established. Kruskal-Wallis rank test and Mann-Whitney U test at the significant level of α=0.05 were used. The following results were obtained: 1. The microhardness was decreased among groups in following order: Z350(3M ESPE, U.S.A), Estelite(Tokuyama Dental, Japan) and Ultraseal(Ultradent, U.S.A). There were significant differences in all groups(p<0.0001). 2. The surface roughness was decreased among groups in following order: Ultraseal XT plus, Palfique Estelite LV and Filtek Z350 flowable, However, there is no statistically significant differences in roughness among Estellite, Z350 and Ultraseal at the significance level of α=0,05, with p=0.116 3. SEM observation of the unworn and worn surfaces revealed the qualitative differences in the wear appearance among groups. The results in this study indicate that flowable resin is better than sealant in aspect of physical properties.

USA)로 충전하였다. 시편을 37℃ 증류수에 24시간 보관한 후 5℃와 55℃에서 10초씩 1000회 열순환하고 2% methylene blue 용액을 24시간 넣어 염색한 뒤, 주수 하에 치아를 협설로 절단하여 색소의 침투 정도를 화상분석현미경을 이용하여 침투깊이를 측정한 뒤 각 군간의 미세누출 정도를 비교하여 침투깊이에 따라 0~3점으로 분류하여 다음과 같은 결과를 얻었다. 1. 범랑질 변연에서의 미세누출은 PL(0.85), SB(0.55), GB(0.50), SM(0.35), SE(0.25) 순이었으며 PL은 SM 및 SE와 통계학적으로 유의한 차이를 나타냈다(p<0.05). 2. 상아질 변연에서의 미세누출은 GB(2.10), SE(1.45), PL(1.40), SB(1.05), SM(0.70) 순이었으며 GB는 SB 및 SM과 통계학적으로 유의한 차이를 나타냈다(p<0.05). 3. 각 실험재료 군내에서 법랑질 변연에 비해 상아질 변연에서 미세누출이 더 크게 나타났으며, SE, PL, GB에서 통계학적으로 유의한 차이를 나타냈다(p<0.05). The objective of this study was to compare the microleakage of five adhesive systems in the enamel and dentin of permanent teeth. Class V cavity preparations with occlusal margins in enamel and gingival margins in dentin were prepared on both buccal and lingual surfaces of 25 extracted human molar teeth. The tested adhesives were: Adper Scotchbond Multi-purpose Plus Adhesive (SM), Adper Single bond 2 (SB), Clearfil SE Bond (SE), Adper Prompt L-Pop (pL) and G-Bond (GB). The results were as follows: 1. At the enamel margins, PL showed the highest leakage value(0.85), and others showed values of SB(0.55), GB(O.50), SM(O.35) and SE(0.25) in decreasing order. There were statistically significant differences in PL vs. SM and PL vs. SE(p<O.05). 2. At the dentin margins, GB showed the highest leakage value(2.10), and others showed values of SE(1.45), PL(1.40), SB(1.05), SM(0.70) in decreasing order. There were statistically significant differences in GB vs. SB and GB vs. SM(p<O.05). 3. Dentin margins showed high dye penetration rate than enamel margins in all material tested groups and there were statistically significant differences for SE, PL and GB.
