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.

Kim, Jae-Duk,Kim, Jin-Soo 대한구강악안면방사선학회 2005 Imaging Science in Dentistry Vol.35 No.4

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.

By use of hollow fiber membrane module, this study examines the value of H(distribution ratio) and Kw(overall mass transfer coefficient) on the Hg(Ⅱ), and used di-2-ethylhexylphospric acid(DZEHPA), tributyl phosphate(TBP), tri-n-octylamine(TOA) as extractant, Also, shown the change of changing the acid. From these experiments and discussions, we have the results as follows. 1. In case of Hg(Ⅱ), the order of well seperated is TOA, DZEHPA, TBP. 2. Concentration decrease ratio have the straight lines for the changing of the time in each systems. So, It was know that the result coincide with theory. 3. The effect of Kw vs. H were shown that in case of H is lower than 10, H is high effect. But H is higher than 10, H is low effect.

This study was conducted to evaluate the blood lead levels in 141 pregnant women who were not occupationally exposed to lead and their umbilical cord, and to identify some differences in blood lead levels by living area. The subjects were all delivered at St. Benedict Hospital in Pusan and the blood lead levels were measured by graphite furance atomic absorption spectrophotometer. The summarized results were as follows. 1. The geometric mean lead levels in maternal and cord blood were 8.0±1.8μg/dl, 5.0±0.6μg/dl respectively. 2. Lead levels in maternal(8.7±1.7μg/dl) and cord blood(5.4μ±0.7μg/dl) of industrial area(n=24) were higher than residential area(n=124) which were 7.9±1.7μg/dl and 5.0±0.6μg/dl respectively(p<0.05). 3. Maternal blood lead concentration was significantly correlated to cord blood lead concentration(r=0.6090, p<0.001), but other variables(maternal age, paternal smoking, birth weight, etc) were not correlated.

Sediment discharge is the quantity of suspended and bed load sediment that moves by saltation, rolling, or sliding on or near the stream bed, passing any cross section of a stream in a unit time. To date no satisfactory means of the sampling of sediment transportation has been developed, although there arc many types of samplers that have been used since about 1390, but all of these samplers are known to have a very low efficency, which changes with varying conditions and hence give only a very approximate estimate of the rate of sediment transportation. This study carried out to estimate the amount of the sediment transportation at the Chungju dam site of Nam Ran River. 1. Price's type currentmeter was used for the estimate of the river discharge. Low velocity: v≥60.96 cm/sec, v=66.2N+1.737 (cm/sec) v≥60.96 cm/sec, v=67.18N+0.823 (cm/sec) High velocity: v=0.673N+0.018 (m/sec) N; Revolution per second 2. To sample the sediment load, US D-49 Depth-Integrating Samplers were adapted. 3. Yearly sediment discharge was estimated by the theoretical formula of F. B. Toffaleti. The amounts of total yearly mean sediment were 2,701,950 ton/year under the total watershed area of 6,683㎢ or 404 T/㎢/year, and yearly mean discharge is 78×100,000,000㎥ 4. Co-relation between (1) the total discharge and sediment discharge and (2) discharge and suspended sediment load are the below. (1) ?? (2) ??

The vision metrology system employing still-video imagery for industrial measurement has the potential of automated measurement with high accuracy. This paper was focussed on ascertaining the impact of free-net technique in self-calibrating bundle adjustment. The practical measurement of a three dimensional test field was conducted using a vision metrology system which was composed of a high resolution still-video camera, a PC-based image mensuration algorithm and a self-calibrating bundle adjustment program. As a result, free-net technique, which does not require any control points with pre-known object space coordinates, went up about 12% in accuracy compared to traditional standard technique. Therefore free-net bundle adjustment is expected to be able to be used efficiently for industrial applications such as dimensional inspection, deformation monitoring and so on.

The primary culture of human nasal epithelial cell monolayer was performed on a Transwell. The effect of various factors on the tight junction formation was observed in order to develop an in vitro experimental system for nasal transport studies. Human nasal epithelial cells, collected from human normal inferior turbinates, were plated onto diverse inserts. After 4 days, media of the apical surface was removed for air-liquid interface (ALI) culture. Morphological characteristics was observed by transmission electron microscopy (TEM). A polyester membrane of 0.4 μm pore size was determined as the most effective insert based on the change in the transepithelial electric resistance (TEER) value as well as the ^14C-mannitol transport study. The ALI method was effective in developing the tight junction as observed in the further increase in the TEER value and reduction in the permeability coefficient (P_app) of ^14C-mannitol transport. Results of the transport study of a model drug, budesonide, showed that the primary culture system developed in this study could be further developed and applied for in vitro nasal transport studies.
