Double primary cancers are two independently developed cancers in an individual. There have been some reports on double primary cancer since Billroth reported it for the first time in 1879. Double primary cancer of the stomach and esophagus has been revealed a very low incidence worldwide. The incidence of an esophageal cancer with another primary cancer is reported to be 9.5∼27%, but double primary cancers in the esophagus and stomach have been rarely reported to our knowledge. In this study, we present here a case of double primary esophageal and stomach cancer in a 66-year-old man because of progressive dysphagia.

Desmoplastic ameloblastoma is a rare histologic variant of ameloblastoma. It shows important differences in anatomic distribution, histologic appearance, and radiographic findings compared with the general type of ameloblastoma. It is histologically characterized by an abundance of densely collagenous stroma and radiographically a mixed radiolucent-radiopaque lesion. We present three cases of desmoplastic ameloblastoma. All the patients complained on buccal swelling with or without pain and the sites of occurrence were the anterior and the premolar region. Plain radiographs showed mixed radiopaque-radiolucent lesion with ill-defined or diffuse sclerotic margin and no external root resorption. Additionally, CT scans revealed buccal expansion and relatively well-defined margin of the lesions. The clinical and radiographic features of the presented cases were compared with those of the desmoplastic ameloblastoma in the previous literatures. (Korean J Oral Maxillofac Radiol 2006; 36 : 63-8)

正常咬合을 가진 混合齒列期 兒童(男子 55名, 女子 46名) 및 成人(男子 41名, 女子 36名)을 對象으로 側貌 頭部放射線規格寫眞上에서 坂本分析法에 의해 頭蓋顔面骨의 成長 變化를 觀察하여 다음과 같은 結論을 얻었다. 9才, 11才, 成人에서 男女別 各 計測項目의 平均値, 標準偏差 및 profilogram을 얻었다. 頭蓋顔面骨의 크기는 深度에서는 9, 11 才에서 男女間 有意差는 거의 나타나지 않았으나, 高徑은 9才에서 男子가 上顔面部 및 下顎部에서 더 크게 나타났으며 11才에서는 N, PTM, PNS를 제외한 全 項目에서 男子가 더 크게 나타났다. 成人에서는 深度에서 GO, 高涇에서 N을 제외한 金 項目에서 男子가 더 크게 나타났다. 9才에서 11才까지의 平均成長量은 上顎 中切齒 및 上下顎 第一大臼齒, 신부에서는 큰 것으로 나타났고 上顔面部, 上顎部에서는 비교적 작은 것으로 나타났으며, 頭蓋顔面骨의 전반적 成長은 S를 中心으로 하였을 때 下方性 長傾向이 優勢한 前下方成長을 하였다. The purpose of this study was to investigate the growth change of craniofacial complex in korean children & adults. The subjects included 55 males and 46 females in children, 41 males and 36 females in adults. A series of 2 lateral cephalometric radiographs obtained from each child at age 9 and 11 and 1 lateral cephalometric radiograph obtained from each adult were analyzed by Sakamoto's coordinate system. The conclusions were as follows : Means, standard deviations and profilograms from measurements were obtained at age 9, 11 and adult. Sexual difference in depth of craniofacial complex was hardly found at age 9 and 11, but in height male was larger than female in upper facial and mandibular portion at age 9 and in all of the items except N, PTM, PNS at age 11. At Adult male was larger than female in all of the items except Go in depth and N in height. Growth increments of upper and lower incisors, upper and lower first molars and chin portion from age 9 to 11 were large, whereas those of upper facial and maxillary portions were relatively small, and the craniofacial complex grew forward and downward, but more downward.

In this study, gall stones from 45 patients were analyzed in vitro. Gall stones from 23 patients were cholesterol stones and the others were non-cholesterol. Correlation with each radiologic physical properties(the number of stones, shape, calcification pattern, Hounsfield units measured by computed tomography) and chemical composition(cholesterol or non-cholesterol) were analyzed. The results revealed that the numbers and size were not related to the chemical composition, but there were significant correlation with faceted stones(p=0.002) or stones with no calcification (p=0.010) and cholesterol composition, and with irregular stones(p=0.000) or stones with dense calcification(p=0.015) and non-cholesterol composition. In study of Hounsfield units, it was difficult to fix the boundary, but the difference between cholesterol composition(138.43±281.81) and non-cholesterol composition(404.32±306.06)was significant(p=0.0109).

The purpose of this study is for confirming about image research by color scheme of saekdong textile fabrics used modern Korean traditional costume. Method of this study is taste analysis by ten person who is specialized in clothing at changwon national university and ten person of the general about seven samples of saekdong that is selling Korea in domestic. The results are as follows. 1. Image of saekdong arrangement of color are dim, noble (stimulus1,4), unpretending-ness(stimulus5,6), calm, sharp(stimulus7), and activity, splendor(stimulus2,3). 2. Stimulus 1 liked everything is most for taste of saekdong arrangement of color. If apply saekdong in design development according to consumers' changed mark and demand, is expected that can do popularization.

This clinical study evaluated the whitening effect and safety of polymer based-pen type BlancTis Forte(NIBEC) containing 8.3% carbamide peroxide. Twenty volunteers used the BlancTis Forte whitening agent for 2 hours twice a day for 4 weeks As a control. Whitening Effect Pen (LG) containing 3% hydrogen peroxide was used by 20 volunteers using the same protocol. The change in shade (ΔE^(*) color difference) was measured using Shadepilot™ (DeguDent) before, during and after bleaching (2 weeks, 4 weeks and postbleaching 4 weeks). A clinical examination for any side effects (tooth hypersensitivity or soft tissue complications) was also performed at each check-up. The following results were obtained. 1 Both the experimental and control groups displayed a noticeable change in shade (ΔE) of over 2 No significant differences were found between the two group (p>0.05) implying that the two agents have a similar whitening effect. 2 The whitening effect was mainly due to changes in a and b values rather than in L value (brightness). The experimental group showed a significantly higher change in b value thus yellow shade than the control(p < 0.05) 3 None of the participants complained of tooth hypersensitivity or soft tissue complications confirming the safety of both whitening agents 8.3%의 carbamide peroxide를 함유한 펜형 코팅용 미백제인 BlancTis Forte (NIBEC, Seosul & JinCheon)를 실험군으로, 3% hydrogen peroxide를 함유한글 Whitening Effect Pen (LG. Seoul) 제재를 대조군으로 각각 피험자 20명에게 2시간씩 1일 2회 제조사의 지시대로 치아표면에 4주간 적용하도록 지시하고 색조개선 효능과 안전성을 평가하였다. 미백 효과는 미백 전 및 미백 2주, 4주 및 미백 종료 4주 후에 Shadopilot™을 이용하여 색 변화를 측정하였고, 매 내원시기마다 모든 환자는 치수생활력 검사와 치주 및 치태 검사를 통해 부작용 여부 (치아과민증 및 구감 내 연조직의 부작용)를 기록한 후 다음과 같은 결과를 얻었다. 1.실험군 및 대조군의 색 변화량 (ΔE)은 2이상으로 인지할 수 있는 색 변화를 보였으며, 두 제품 간에는 통계적으로 유의한 차이를 보이지 않아 (p > 0.05) 유사한 미백효능을 나타냄을 알 수 있었다. 2,미백효과는 명도의 개선보다는 주로 a. b값의 변화에 의한 것으로 특히 실험군에서 b값의 변화, 즉 황색조의 개선효과가 대조군에 비해 유의성 있게 높은 것으로 나타났다 (p <0.05). 3.치아나 치은의 과민증이나 이상증상을 호소하는 피험자는 없어 두 제품 모두 안전성을 확인할 수 있었다.
