But that of plot applied wood charcoal 10 Mg/㏊ over was trend to decrease.

녹차 및 결명자 추출물의 교정용 브라켓과 치면 사이의 경계부에서 분리된 mutans streptococci에 대한 항균작용

임성훈,서정순,윤영주,김광원,유소영,김화숙,국중기,이병래,차종희,박재윤 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.5

본 연구는 치아우식증에 관련된 Mutans streptococci 표준균주 및 임상분리 균주의 성장억제를 유도할 수 있는 천연 생약추출물을 검색하기 위하여 실시되었다. 녹차추출물은 CHMC-2032를 사용하였으며, 결명자 추출물은 50% 에탄올을 이용하여 얻었다. 이들 추출물의 Mutans streptococci 표준균주 및 교정환자들에서 브라켓과 치면 사이의 경계부에서 분리된 각각 10 균주씩의 S. mutans 및 S. sobrinus에 대한 최소성장억제농도를 액체배지 희석법으로 구하였다. 그 결과 CHMC-2032의 S. mutans 및 S. sobrinus의 표준 균주, S. sobrinus의 대부분 임상분리 균주에 대한 최소성장억제농도는 5 mg/ml이었다. 그러나 결명자 추출물에 의한 S. mutans 및 S. sobrinus에 대한 세균 성장억제 효과는 미미하였다. 본 연구 결과 치아우식증의 예방적 측면에서 결명자차보다는 녹차를 마시는 것이 유리하며, CHMC-2032를 이용하여 구강양치용액을 제조하여 사용할 경우 교정환자를 포함하여 대부분의 사람에게서 치아우식증 예방 효과가 있으리고 추정된다. Mutans streptococci is the major causative factor in dental caries. Especially, orthodontic patients with fixed appliance are a risk group for dental caries. Because fixed appliances attached on teeth may change the environment of dental plaque, the enamel decalcification or dental caries around the bracket and band is a major side effect of orthodontic treatment. The aim of this study was to search plant extracts that have antimicrobial effect on mutans streptococci. Seed-extract of Casio tora were prepared with ethanol and CHMC-2032, the leaf-extracts from Camellia sinensis extract, was obtained extract, 2 type strains and 20 clinical isolates of mutans streptococci isolated from the interface between orthodontic brackets and tooth surfaces in the orthodontic patients were used in this study. The minimal inhibitory concentration of CHMC-2032 was 5 mg/ml on the S. mutans KCTC 3065, S. sobrinus KCTC 3088, and 8 clinical isolates of S. sobrinus. However, there was no antibacterial effect of seed-extract of C. tora on mutans streptococci. These data suggest that green tea may be more effective than the tea prepared from C. tora in the prevention of enamel decalcification or dental caries around brackets.

Background/Aim: Angiosarcoma is a rare and aggressive liver malignancy originated from endothelial cells. Due to non specific symptoms and signs, it is difficult to diagnose at the early stage, radiologic findings of hepatic angiosarcoma are non specific, and it is not easy to differentiate with hemangioma or other liver malignancy. We reviewed the clinical courses of hepatic angiosarcoma those histologically confirmed. Patients and Methods: Patients who have been diagnosed at Keimyung University Dongsan Hospital between 2001 and 2011 were enrolled. we retrospectively reviewed the pattern of disease detection, the sites of metastasis , treatment responses, and prognosis. Results: 1.8 patients were histologically confirmed as primary hepatic angiosarcoma. Mean age was 66.3 year-old (41-80 yo). 4 patients were male. All patients` serum HBsAg and anti-HCV were negative and five patients were heavy alcoholics. 2. Only two patients (25%) were diagnosed by radiology findings, and then definitive diagnosis was made on the basis of percutaneous needle biopsy in seven (87.5%) and operation in one (12.5%). 3. At initial disgnosis, extrahepatic metastasis were detected in three patients (37.5%), and metastatic site were spleen and lung (n=1), pericardium (n=1), and bone (n=1). 4. Three patients (37.5%) received conservative treatment only, one (12.5%) under- went surgical resection and four (50%) received chemotherap. Median survival time in treatment group were 427days and only 36days in conservative group (p value = 0.022). Conclusion: Only few patients of hepatic angiosarcoma can be diagnosed by radiologic findings, we have to actively consider liver biopsy to confirm. More than one third of patients already had metastatic lesion at initial diagnosis, and the clinical courses were very poor. So, we have to consider aggressive treatment for better survival.

Traumatic bilateral dislocation of the hips caused by traffic accidents in a 23 years old male is reported. The right hip was dislocated in posterior and the left hip in anterior without any fracture. The successful closed reduction of hip were obtained under generally anesthesia in four hours after injury. He was in bilateral Buck's extension traction for six weeks and followed two weeks for active joint exercise in bed. From the eight weeks after injury he was began to have parallel bar walking with minimal weight bearing as possible as he can for four weeks. He was started full weight bearing without any support in three months after injury. The follow-up observation was made for 10 months and there was no any radiological change obtainable yet with good function of hips.
