Metastatic hepatocellular carcinoma on the mandible : A case report
Kim, Jin-Soo,Kim, Jae-Duk 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.4
Hepatocellular carcinoma is one of the most common cancer worldwide, primarily affecting those in regions with a high prevalence of viral hepatitis. However, the metastasis of hepatocellular carcinoma to the oral cavity is a rare phenomenon. This report presents a case of metastatic hepatocellular carcinoma in the left mandibular angle and ramus region of a 62-year-old man. Panoramic radiograph revealed an ill-defined radiolucent lesion extending from the retained root of the mandibular left second molar into the ascending ramus. The lesion had irregular and ill-defined margins.

Purpose : To classify and describe the characteristic features of MRI of some ameloblastoma variants. Materials and Methods : The MR images, CT images, and panoramic radiographs in 5 cases were retrospectively examined as follows. First, the contents of ameloblastomas were devided into two portions of either solid or cystic components on the basis of MR signal intensities. The signal intensity within the solid or cystic portions was classified as homogeneous or heterogeneous. Next, the characteristic internal feature of the lesion on T1W1 or T2WI was described. The signal intensities were classified into low, intermediate, slightly high, high, and strong high signal intensity. Results : Unicystic lesion showed homogeneous high signal intensity (SI) on T2W2 and the rim enhancement of the surrounding area including the mural nodule and the thick wall except the central portion on Gd-T1W1 Solid type revealed heterogeneous and high SI area with strong high SI area on T2W2. On Gd-T1W1, the area corresponding to the low signal spot on T1W1 and the strong high signal spot on T2W1 showed low SI. Hybrid type showed slightly enhanced capsular structures and low SI for the round bony septa and the areas connecting the mixed and cystic lesions on T2W1 and Gd-T1W1. Conclusion : MRI could easily assess the relationship between the mixed and cystic findings in ameloblastoma.

Male Sprague-Dawley rats were orally treated with low and high-doses (50mg and 100mg/Kg of body weight) of either fermented-citrus extract or citrus extract dissolved in 20% ethanol during 6 weeks. The body weight, the level of plasma total choresterol were slightly reduced in higher dose(100 mg/Kg of body weight) of fermented-citrus extract comparing with other groups. but was not significantly different. The fat liver formation induced by high-fat diet were significantly reduced in rats administrated with fermented citrus-extract. This result suggest that fermented-citrus extract have hepatoprotective activity against high-fat diet induced fatty liver.

The objective of this study is to conduct land cover classification respectively using Landsat 1M data collected on Oct., 1985 and KOMPSAT-l EOC data collected on Jan., 2000 covering Gumi city, Gyeongbuk Province and to detect urban change by comparing between both land cover maps. Multispectral images of Landsat 1M have spatial resolution of 30m are well known as useful data for extracting information related to landcover, vegetation classification, urban growth analysis and so forth. In contrast, as KOMPSAT-1 EOC collects panchromatic images with relatively high spatial resolution of 6.6m We try to analyze how accurate landcover classification result is able to be derived from the panchromatic images. As the results of the study, the KOMPSAT EOC data with high resolution of 4.5 times greater than Landsat TM data showed higher classification degree. We tried to find out optimal band combination for land cover classification using multispectral imagery. It was ascertained that the built-up region was extended by three to four times in the last 15 years between 1985 and 2000. In the contrast, it was shown that the forest region was decreased by 15% to 27% and the grass region including agricultural region was decreased by 28% to 45%.

The aims of this study are to demonstrate the reliability and the validity of the Korean version of Behavioral Dyscontrol Scale (BDS-K.) and to present the normative values of BDS-K among the Korean elderly. The BDS-K was administered in a standardized manner to 1,389 healthy volunteers aged over 65 years recruited from the cornmunity. The elderly with serious neurological, medical or psychiatric disorders were excluded using screening tests. BDS-K showed good intemal consistency (Cronbach's alpha=0.812), test-retest reliability (r=0.88) and inter-rater reliability (r=0.99). Age and educational level were found to affect BDS-K score. Based on this result, normative values of BDS-K. were calculated by age and educational level. The validity of the BDS-K were demonstrated in comparison with MMSE-KC (r=0.72). BDS-K is reliable and valid instrument for measuring executive function of the elderly. The normative values suggested by this study can be widely used as reference values to objectively interpret BDS-K scores of the Korean elderly.

The change of body weight, digestion and absorption rate, the weight of several kinds of the internal organs, serum protein, cholesterol, sugar and the inorganic ingredients induced by sanshool in rates were investigated. The increase of body weight lowered in the additional group of 1% and 5% sanshool The effeciency of lowered in the additional group of 1% and 5%. The heart weight of the internal organs was decreased in the additional group of 5% sanshool. The lung weight showed a little decrease in the additional group of 5%. There wasa little change in other internal organs. α₁globulin of in the serum was decreased in the additional group of 5% sanshool. On the other hands, γ-globuin showed a remarkable increase in additional group of 1% and 5%. There were little change in other serum proteins. The gluose in the serum showed increase in the additional group of 5% sanshool, and cholesterol showed a little increase in the additional group of 1%.
α-Sialon 세라믹스(X=0.15)의 기계적 성질에 미치는 소결분위기 및 ZrO₂의 첨가 영향

4.82 wt% AIN and 2.95 wt% Y₂O₃were added to Si₃N₄as sintering agents in order to have α-Sialon composition of X=0.15 and monoclinic ZrO₂between 0 to 10 wt% was admixed with Si₃N₄. Si₃N₄based ceramics were fabricated by hot-pressing at 1750℃ for 90 min under 30 MPa in argon and nitrogen atmospheres Effects of sintering atmospheres and addition of ZrO₂on mechanical proporties of Si₃N₄based ceramics were investigated. As ZrO₂content increased, the fraction of α-Sialon tended to decrease and the amount of cubic ZrO₂increased because Y₂O₃acted as the stabilizer of ZrO₂. The sintering atmospheres didn't affect on the sintering behavior and the product phases in hot-pressing of Si₃N₄. Bending strength increased when ZrO₂was added up to 3 wt%. Hardness showed tendency to decrease with ZrO₂content. ZrO₂didn't contribute to the increase of fracture toughness because stabilized cubic ZrO₂was produced by the added Y₂O₃.
