To describe the usual and unusual CT findings of heterotopic pancreatic of the stomach and to evaluate the usefulness of dynamic contrast-enhanced CT with water as an oral contrast agent in diagnosing heterotopic pancreas We retrospectively reviewed CT findings in 10 patients with pathologically proved gastric heterotopic pancreas by operation (n=9) or endoscopic resection (n=1). In three patients, conventional CT with diluted Gastrografin solution as an oral contrast agent was performed. In seven patients, two-phase dynamic CT scans after ingestion of 600-800 ml of water were obtained in the early phase and equilibrium phase. Dynamic CT findings of heterotopic pancreas were correlated with histopathologic findings. All 10 heterotopic pancreatic rests were detected with conventional CT or dynamic CT. In seven cases who underwent dynamic CT after ingestion of water, highly enhanced mucosal layers overlying the lesions were identified and all lesions were well delineated in the submucosal layer In four of these seven cases, heterotopic pancreas showed high enhancement similar to that of adjacent normal pancreatic enhancement in the early phase of dynamic CT. The usual CT findings of gastric heterotopic pancreas were oval-shaped submucosal masses (<3cm) in the gastric antrum. The unusual CT findings were infiltrating heterotopic pancreas into the muscle layer in one, cystic dilatation of heterotopic pancreatic ducts in two, and malignant change with mucin secreting cystadencoarcinoma in one. Gastric heterotopic pancreas usually showed oval-shaped submucosal masses (<3cm) in the gastric antrum with high enhancement similar the that of pancreatic enhancment in the early phase of dynamic CT. Our results suggest that contrast-enhanced dynamic CT after ingestion of water may be helpful in diagnosing gastric heterotopic pancreas.

본 연구는 화차의 비율별 제조공정에 따른 화차의 관능적 품질을 평가하기 위해서 수행되었다. 녹차와 꽃의 시료에 대한 색도중 L, a, b값은 녹차가 29.93, -8.24, 9.27로 녹색을, 황국은 47.20, -1.69, 29.12로 밝은 황색을, 흑장미는 37.18, 4.47, 4.12로 흑적색을 띠웠다. 색상과 채도는 황국이 -17.23과 29.17로 가장 높아 색상이 가장 밝고 선명하였으며, 흑장미는 0.92와 6.08로 색상이 어둡고 둔탁한 적색을 띠워 녹차에 꽃을 혼합할 경우 시각적으로 황국은 쉽게 구별이 되었으며 흑장미는 쉽게 구별되지 않았다. 황국 화차는 꽃의 비율이 증가할수록 국화향, 상쾌하고 개운한 단맛의 증가와 더불어 떫은 맛이 감소하였으나, 혼합비율이 9:2 이상일 경우에는 쑥냄새와 같은 강한 국화향이 증가하여 녹차 고유의 향은 거의 상쇄되는 경향이었다. 장미 화차는 장미꽃이 증가할수록 시큼한 장미향이 강하게 증가하였고, 탄닌성분이 많아 떫고 텁텁한 맛과 시큼한 맛이 강한 것으로 평가되었다. 녹차에 알맞은 꽃의 혼합율은 9:1이하의 비율로 혼합했을 때 황국과 흑장미의 꽃잎색이 녹차와 어울려 전체적인 조화성과 풍미, 시각적 아름다움을 증가시켰다. 녹차에 꽃을 혼합한 화차는 녹차 단일의 차보다는 시각적 즐거움과 독특한 방향성이 부가되어 맛과 향이 풍부한 기능성 꽃차 개발에 좋은 재료로 평가되었다. This experiment was carried out to investigate the effect of mixed ratio on the sensory evaluation in manufacture of functional flower tea. Among the chromaticity about green-tea and material flower, the amount of L, a, b of green tea was 29.93, -8.24, 9.27 with green, the amount of a yellow chrysanthemum(C.indicum) was 47.20, -1.69, 29.12 with bright yellow, the amount of a black rose(Rosa hybrida)is 37.18, 4.47, 4.12 with dark red. The yellow chrysanthemum has brightest and most distinct color with -17.23 hue and 29.17 chrome value, but the black rose has dark dead red color with 0.29 hue 6.08 chrome value. When the yellow chrysanthemum mixed with green tea, it was easily distinguished with naked eye. But the black rose was not distinguishable easily. As the retio increase, the yellow chrysanthemum tea has more chrysanthemum scent, increase of refreshing and relieved sweetness, and less astringent taste. If the mixed rate was over 9:2, original scent of green tea was almost offset with strong chrysanthemum scent like mugwort's. As the ratio increase, the rose tea has strongly increased sourish, and because of the tannin it was appraised strong astringent, unpleasant, sourish taste. The best-mixed ratio of green tea and flower is 9:1. When it mixed at this ratio, the yellow chrysanthemum and petal color of black rose was well matched with green tea, and the tea has general harmony and flavor and it is visually beautiful. Flower tea, green tea from flower, has added visually joy and unique fragrance, it was valued as fine material for rich taste and scent technical tea development.

The purpose of this study was to evaluate the effect of helical CT during the portal venous phase after oral ingestion of water in the preoperative staging of advanced gastric carcinomas. Of the patients underwent helical CT scanning for preoperative staging of gastric carcinoma, 70 patients with pathologically proved advanced gastric carcinomas were selected in this study. The patients ingested 600-800m1 of water as a oral contrast agent before CT scanning. A total 130150ml of nonionic contrast material was administered at the rate of 4ml/s. We obtained portal venous phase images at 60 s and equilibrium phase images at 3 min after the start of bolus administration of intravenous contrast material. Two-phase CT findings were prospectively evaluated and correlated with histopathologic findings according to TNM classification. The primary tumors were detected on CT scans in 69 (98.5%) of 70 cases. The accuracy of CT for T staging was 74.3% (52 of 70 cases). T staging was understaged in 13 cases (18.6%) and overstaged in five (7.1%). The accuracy for N staging was 67.1% (47 of 70 cases). N staging was understaged in 16 cases (22.9%) and overstaged in seven (10%). Our results suggest that helical CT during the portal venous phase can improve the accuracy of CT in the preoperative staging of advanced gastric carcinomas.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

조문기,이진우,차경석,정동화 대한치과교정학회 2007 대한치과교정학회지 Vol.37 No.1

본 연구는 Ⅱ급 부정교합자에서 액티베이터 사용 후, 하악골의 변화에 따른 atlas의 위치 및 형태 변화를 조사하고, 그에 따른 치료 효과를 예측해 보고자 시행하였다. 실험군으로 Ⅱ급 부정교합자로써 액티베이터 치료를 시행한 경우 1군(총30명, 남자 15, 여자 15명), 대조군들로 Ⅱ급 부정교합자로 액티베이터 치료를 받지 않고, 교정치료를 받은 2군(총 22명, 남자 12, 여자 10)과 Ⅰ급 부정교합자로 치료를 받은 환자 3군(총 22명, 남자 12, 여자 10)으로 총 세 개의 군으로 나누었다. 치료 전(T1), 액티베이터 사용 중지 및 치료 중간시기(T2), 치료 종료(T3)시의 측모두부방사선사진을 통해서 골격 형태 계측 및 atlas 형태 계측을 시행하였다. Ⅱ급 액티베이터 사용 결과 액티베이터를 사용하지 않은 Ⅱ급 부정교합자 군에 비해 치료 종료 시 다음과 같은 계측치 들에서 골격적인 효과가 나타났다: ramal height, body length와 effective body length는 증가하였고, ANB는 감소하였다. Overjet은 두 군 사이에서 액티베이터 사용 후 유의한 감소가 일어났으나, 치료 종료 시에는 유의한 변화가 없었다. 세 군 모두에서 FH에 대한 atlas의 시계방향 회전이 나타났으나, 실험군 1군에서 대조군 2, 3군에 비해 유의하게 atlas가 FH에 대해 시계방향 회전되는 결과가 나타났다. 1군이 3군에 비해서 atlas의 유의한 후방이동을 보인 것을 제외하고는 세 군 사이의 atlas의 전, 후방적 위치나, 형태의 크기 변화에 있어 유의한 차이점은 없었다. 위의 결과들을 고려해 볼 때 atlas의 장축의 시계방향 회전은 액티베이터의 사용 효과로 생각되며, 이는 차후 Ⅱ급 부정교합자에서 액티베이터 치료 효과를 판단하는 또 하나의 지표가 될 수 있다고 생각한다. Objective: Previous studies have reported that morphological features of the first cervical vertebra(atlas) have been associated with mandibular growth direction. The purpose of this study was to show the possible positional and morphological changes of the Atlas from activator treatment in Class Ⅱ malocclusion patients. Methods: Lateral cephalometric radiograph tracings were made at initial, middle and final stages of treatment. Angular and linear measurements of skeletal and morphological features were measured on the anatomical landmarks and reference planes. Results: The skeletal effects of activator treatment on Class Ⅱ malocclusion patients were evident on ramal height, body length, effective body length, ANB, and overjet. Clockwise rotation of the long axis of the Atlas was found in Group 1, but there was no inclination change of the Atlas in groups 2 and 3. There was no significant correlation between anterior and posterior positions of the atlas or morphological change in all groups. - except for posterior movements of the Atlas found in group 1. Conclusion: Clockwise rotation of the atlas axis resulted from activator treatment in CI Ⅱ malocclusion patients. Change in atlas axis can be thought of as an indicator for success of activator treatment.

趙誠旭,車敬石 대한치과교정학회 1992 대한치과교정학회지 Vol.22 No.1

To find out the differences between periodontal ligament cells (PDL cells) and gingival fibroblast cells (GFB cells), alkaline phosphatase, a marker enzyme for osteoblast, was used to measure the activities and 45CaCl₂isotope was used to find out cellular and release of 45Ca, a requisite for bone formation, PDL cells and GFB cells from 1 to 5 passages were also measured in alkaline phosphatase activity assay. By the use of above methods, followings were concluded that the PDL cells and the GFB cells have characteristics that are different from each other. In that PDL cells showed large amount of calcium uptake ad large amount of calcium release in initial stage, they seem to possess characteristics which are similar to osteoblast-like cells. 1. The PDL cells, in contrast to the gingival fibroblast, showed exceedingly high alkaline phosphatase activity which was highest at the second passage, decreasing thereon. But gingival fibroblasts cells showed no distinct differences in alkaline phosphatase activity as the passage were elapsed. 2. For both PDL cells and GF cells, the 45Ca uptake was greatest at 2 hours period. The PDL cells showed higher measuring than GFB cells through out the whole time period. 3. Whereas the GFB cells showed slow increase of 45Ca release as time relapsed, the PDL cells showed rapid increase of 45Ca release.
