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)

The causes of pyogenic liver abscess has been known as biliary tract disease or intrabadominal infection but the large proportions of the patients has no apparent underlying disorders. Recently colonic mucosal lesions were reported in patients with cryptogenic liver abscess and it has been suggested that colonic mucosal break may play a role in developing liver abscess in otherwise healthy patients. We experienced a patient of severe recurrent liver abscess complicated with endophthalmitis only 3 months after successful treatment of initial cryptogenic liver abscess and a polypoid colon cancer was discovered by chance. It seems prudent to proceed colonoscopic examination in patients with cryptogenic liver abscess especially when it is recurrent.

Anthocyanins, providing the bright red-orange to blue-violet colors, flavonoid-derived pigments with strong antioxidant activity that have benefits for human health. We isolated RsMYB1, which encodes an R2R3 MYB transcription factor (TF), from red radish plants (Raphanus sativus L.) that accumulate high levels of anthocyanins. RsMYB1 shows higher expression in red radish than in common white radish, in both leaves and roots, at different growth stages. regulatory genes. Transient expression of RsMYB1 in tobacco showed that RsMYB1 is a positive regulator of anthocyanin production. Also, the synergistic effect of RsMYB1 with B-Peru was larger than the effect of Arabidopsis plants stably expressing RsMYB1 produced red pigmentation throughout the plant, accompanied by up-regulation of the six structural and two regulatory genes for anthocyanin production. This broad transcriptional activation of anthocyanin biosynthetic machinery in Arabidopsis included up-regulation of TRANSPARENT TESTA 8, which encodes a bHLH-type TF. These results suggest that overexpression of RsMYB1 promotes anthocyanin production by triggering the expression of endogenous bHLH genes as potential binding partners for RsMYB1. In addition, RsMYB1-overexpressing Arabidopsis plants had a higher antioxidant capacity than did non-transgenic control plants. Taken together, RsMYB1 is an actively positive regulator for anthocyanins biosynthesis in radish plants and it might be one of the best targets for anthocyanin production by single gene manipulation being applicable in diverse plant species.

우리나라의 지방대학은 지속되는 대학진학자의 감소로 심각한 존립 위기를 맞고 있다. 지방대학이 당면한 학생확보 문제는 법과 제도로 정부가 노력해야 할 부분이 있는 동시에 개별대학이 전략적 차원에서 스스로 노력해야 할 부분도 있다. 본 연구는 지방소재 사립대학이 학생확보 문제에 접근하는 하나의 방안을 제시한다. 응답자들로부터 조사된 대학간 유사성자료를 바탕으로 다차원 척도법으로 지각도를 작성하여 경쟁하고 있는 대학군을 파악하였다. 기존 연구로부터 제시된 대학선택기준에 대하여 각 경쟁대학의 성과를 추정하기 위하여 회귀분석을 이용 지각도 위에 속성 벡터로 나타내었다. 본 연구의 분석대학은 규모와 설립역사가 비슷한 사립대학들(c ,e, f, g)과 지각도상에서 가깝게 위치하여 서로 경쟁적 관계에 있음을 알 수 있고 사회적 평판과 교육의 질은 비교적 높은 것으로 평가 되고 있다. 재정적 부담이 큰 대학으로 인식되고 있으나 사립대학 모두가 비슷한 평가를 받고 있음을 알 수 있다. 대학의 지리적 위치는 낮게 평가되고 있으나 경쟁대학과 차별성은 크지 않은 것으로 보인다. 그리고 국제화, 대학시설, 취업률 기준에서 분석대학은 경쟁대학과 매우 높은 경쟁관계에 있음을 보여 주고 있다. Private universities, located in local provinces in Korea, face a severe crisis because of declining students enrollment. The difficulty of students securement can be lessened through government policy in part, yet each university can make its best effort with strategic approach to tackle the problem. This study aims to suggest one simple method to this issue. On the basis of similarity data between the pairs of universities, competitors can be identified through multidimensional scaling method in perceptual map. Regression analysis produces set of property vectors which indicate the performance result of individual university for university selection criteria. Perceptual map shows that base university competes mainly with private universities such as c,e,f,and g. It is shown that base university receives high perception from students in social reputation and education quality criteria. Financial burden criteria is fairly disadvantageous factor to base university. However, this factor reveals similar to all private universities. University location is another low-rated factor, but not much difference are found with competitors. Base university competes with universities c,e,f,and g in the areas of globalization, university facility, and employment rate as well.

Treatment responses of $N_0$ stage nasopharyngeal carcinoma were firstly analyzed comprehensively to evaluate long term outcomes of patients and identify prognostic factors. A total of 610 patients with $N_0$ NPC, undergoing definitive radiotherapy to their primary lesion and prophylactic radiation to upper neck, were reviewed retrospectively. Concomitant chemotherapy was administrated to 65 out of the 610. Survival rates of the patients were calculated using the Kaplan-Meier method and compared by log-rank test. Prognostic factors were identified by the Cox regression model. The study revealed the 5-year and 10-year overall, disease-free, disease-specific, local failure-free, regional failure-free, locoregional failure-free and distant metastasis-free survival rates to be 78.7% and 66.8%, 68.8% and 55.8%, 79.9% and 70.4%, 81.2% and 72.5%, 95.8% and 91.8%, 78.3% and 68.5%, 88.5% and 85.5%, respectively. There were 192 patients experiencing failure (31.5%) after radiotherapy or chemoradiotherapy. Of these, local recurrence, regional relapse and distant metastases as the first event of failure occurred in 100 (100/610, 16.4%), 15(15/610, 2.5%) and 52 (52/610, 8.5%), respectively. Multivariate analysis showed that T stage was the only independent prognostic factor for patients with $N_0$ NPC (P=0.000). Late T stage (P=0.000), male (P=0.039) and anemia (P=0.007) were independently unfavorable factors predicting disease-free survival. After treatment, satisfactory outcome wasgenerally achieved in patients with $N_0$ NPC. Local recurrence represented the predominant mode of treatment failure, while T stage was the only independent prognostic factor for overall survival. Late T stage, male gender, and anemia independently predicted lower possibility of the disease-free survival.
