        뇌낭미충증에 대한 전산화 단층촬영소견

        홍진교 대한영상의학회 1980 대한영상의학회지 Vol.16 No.2

        Cysticercosis is a parasitic disease in which man serves as the intermediate host of Taenia Solium, the Pork tapeworm. The computed tomographic findings fo 25 cases of intracerebral cysticercosis proven by pathologic and/or clinical findings during past 2 years were analysed. The results were as follow : 1. The sex distribution was 19 males and 6 females and 56 percent of the patients were seen in fourth and fifth decades. Th most common symptom was epilepsy(72%). 2. The C.T. findings in precontrast study were varied ; such as ill definded low density (48%) , cystic low density (20%), dilated ventricles (20%), ill defined low density with isodense nodule (18%), cystic low density with isodense mural nodule (12%), and calcification(8%). 3. The areas of involvement were 20 cases (80%) of parenchymal form, 3 cases(12%) of ventricular form and 2 cases (8%) of mixed form. 4. the contrast-enhanced 13 cases were 5 nodular, 5 ring or rim-like and 3 mixed type enhancement , while 12 ases were not enhanced. 5. C.T scan demonstrated more precise location and extents of cerebral cysticercosis, especially in parenchymal form. It was considered to be important in determination of surgical feasibility and its approach.

        뇌전이암의 전산화단층촬영소견에 대한 고찰

        홍진교 대한영상의학회 1982 대한영상의학회지 Vol.18 No.3

        Computed tomography was proved to be the most accurate diagnostic tool in the analysis of brain metastasis than any other classical methods. The authors studied CT findings of intracranial metastasis in 31 cases proven clinically and histologically. The results were as follows: 1. Age distribution of the cases was 15 males and 16 females with peak age of 6th decade in males and 4th decade in femalse. 2. Metastatic lesions were multiple in 18 cases and single in 13 cases. 3. The most common degree of edema was grade III, 43% of total metastatic foci. Marked edematous low densities with relatively small nodular high densities in precontrast scan and variable contrast enhancement of the nodula densities were the most frequent CT findings. 4. No specific characteristics according to the primary cancer was noted. All four cases of choriocarcinoma showed hemorrhagic tendency.

        두부외상에 대한 자기공명영상

        홍진교 대한영상의학회 1986 대한영상의학회지 Vol.22 No.1

        In the diagnosis of head injury, Magnetic Resonance Imaging *MRI), like cT, is an effective method of distinguishing between intracerebral and extracerebral lesions. In our experience of MRI, early hematomas are almost isointense by Saturaion Recovery(SR) method, so these must be performed with Spin Echo (SE) method for better visualization of hematomas. Isodense subdrual hematomas, which is a diagnostic dilemma on CT images, are cleary seen on MRI. Delayed hematomas or residural parenchymal lesions are better demonstrated on MRI than on CT . Direct cornal , sagittal images andmultiplanar faciligy of MRI provides excellent visualization of the location and shape of extracerebral collection of hematoma. For the screening of head traumas, SE method is a technique of choice because of its excellent sensitivity.

        洪進敎,柳總根 고려대학교 의과대학 1985 고려대 의대 잡지 Vol.22 No.3

        The comparative study was conducted on the effect of rice diet and rice mixed with barley(10%, 30%, 60%) diet on accumulation of adipose tissue and levels of triglyceride(TG), phospholipid(PL), total cholesterol(TC), and high density lipoprotein(HDL)-cholesterol in serum of albino rats(Wistar). 1. Adipose tissue accumulation and levels of TG, PL, TC serum in were lower in rice mixed with barley diet group than in rice diet group to the extent that the more barley was mixed with rice, the lower the levels of the above parameters. 2. HDL-cholesterol level was lower in the group where more barley was mixed with rice at 2 weeks after feeding. Rice diet group showed the highest level. 3. TC-HDL cholesterol level was lower in rice mixed with barley diet group than in rice diet group. 4. HDL-cholesterol level decreased in all the diet groups as the feeding period went, in contrast that TC-HDL cholesterol level increased gradually during the same period. 5. The average contents of NDF, ADF and lignin in barley(38% polished Convered barley) were 5.25g%, 2.078% and 1.11g%, respectivity. Based on the above observations it can be deduced that rice mixed with barley diet has the effect to suppress the adipose tissue accumulation and serum elevation of lipid level mainly by dietary fibers contained in barley to the extent that the more barley contained in diet, the more inhbitory effect it shows.
