The partial splenectomy was performed on the basis of the arterial distribution in order to reduce complications. The spleen consists of the various histologic components that have different functions. But we can not find the reports whether the distribution of red pulp, white pulp and trabecula is uniform or not according to the regions of the spleen. We used 15 spleens from Korean[male 8, female 7 and age 17-74]. The volume was measured with the mass cylinder. The 1cm3 blocks were selected in 5 different regions. Whole splenic slices by celloidin embedding were made from two spleens. The point counting method with eyepeice reticule was used for the measurement of the distribution of red pulp, white pulp and trabecula. The results were as follows : 1. The volume of the spleen was ranged 45-158ml and the individual difference was marked. The male spleen was larger than female`s [p<0.05]. 2. The ratio of red pulp, white pulp and trabecula of the paraffin embedding preparations was 83.2, 10.9, and 5.9% respectively. There was no significant difference in the distribution of the histologic components among five regions[upper, hilum, middle, outer, and lower]. 3. The distribution of red and white pulps in whole splenic slices was not uniformity. The ratio of red pulp, white pulp and trabecula in whole splenic slices was 80.1, 13.4 and 6.5% respectively. These results showed no significant difference with those of five regions of the spleen.

PURPOSE: To date, the high spatial frequency algorithm (HSFA) which reduces image smoothing and increases spatial resolution has been used for the evaluation of parenchymal lung diseases in thin-section high-resolution CT. In this study, we compared the ultrahigh spatial frequency algorithm (UHSFA) with the high spatial frequency algorithm in the assessment of thin section images of the lung parenchyma. METHODS AND MATERIALS: Three radiologists compared the UHSFA and HSFA on identical CT images in a line-pair resolution phantom, one lung specimen, 2 patients with normal lung and 18 patients with abnormal lung parenchyma. RESULTS: Scanning of a line-pair resolution phantom demonstrated no difference in resolution between two techniques but it showed that outer lines of the line pairs with maximal resolution looked thicker on UHSFA than those on HSFA. Lung parenchymal detail with UHSFA was judged equal or superior to HSFA in 95% of images. Lung parenchymal sharpness was improved with UHSFA in all images. Although UHSFA resulted in an increase in visible noise, observers did not found that image noise interfered with image interpretation. The visual CT attenuation of normal lung parenchyma is minimally increased in images with HSFA. The overall visual preference of the images reconstructed on UHSFA was considered equal to or greater than that of those reconstructed on HSFA in 78% of images. CONCLUSION: The ultrahigh spatial frequency algorithm improved the overall visual quality of the images in pulmonary parenchymal high-resolution CT.

Ninety-three dry mandibles in Korean adults were radiographed and fifty-two hemimandibles were sectioned in an attempt to analyze the intramandibular courses of the mandibular canal and the internal structure of the mandibles. On radiographs, the intramandibular course of the mandibular canals was most in which located in the middle portion of the mandible, the shape of the mandibular canals was almost round and the average diameter of the mandibular canals was 2.0 +/- 0.4mm, encapsulated by thin cortical plates of 0.5mm thickness on sectioned specimens. In regard of facio-lingual relation, the prevalence of pattern which the mandibular canal ran nearly to the lingual cortical plate, and turned abruptly towards the buccal side was 70% of observed specimens. According to superior-inferior relation, the prevalence in which mandibular canals ran inferiorly, anteriorly and then, had an angle superiorly in the second mandibular molar region was 39.0%. Taken all together, in most of the case, the anterior border of the mandibular canal is located around the premolar region, and the mental foramen is opened nearly the second premolar. Therefore, it may be suggested that osteotomy has to be taken at the anterior place next to the canine region, at the 2.4mm below to the mental foramen on genioplasty.

Human caspase-2, Ich-1 (Ice and Ced-3 homolog), has two different forms of mRNA species derived from alternative splicing, which encodes Ich-1 and Ich-1s. Ich-1v which induces apoptosis is antagonist of Ich-1s which suppresses Rat-1 cell death by serum deprivation. To investigate functions of Ich-1 and Ich-1s in T celi apoptosis, the fusion DNA constructs were made with the ecto and transmembrane of CDB and Ich-lv or Ich-1s and CDS-Ich-1 or CD8-Ich-1s chimeric protein was transiently expressed on Jurkat T cells. Tyrosine phosphorylation of intracellular proteins was induced in these transfectans when activated shortly by anti-CDB Ab. CDB-Ich-li transfectant in serum-rich condition and CDB-Ich-ls transfectant in serum-deprived condition underwent apoptosis when treated with anti-CDS Ab or incubated with NIH3T3 cells expressing stably Fas-L on their surface. We also made six antisense DNA constructs which could specifically inhibit the expression of Ich-1v, Ich- 1s, and then they were transiently transfected into Jurkat T cell. The overexpression of both of the antisese- Ich-1 against N-terminal 42 bp and against C-terminal 366 bp inhibited apoptosis through Fas signalling. But, when three different forms of antisense-Ich-1s were overexpressed in their transfectants, antisense-DNA against N-terminal 197 bp increased knd the one against C-terminal 66 bp inhibited apoptosis, instead the full size of antisense-DNA did not give any effects on apoptosis through Fas pathway.

Cystic hepatocellular carcinoma is unusal, and visualization of the cystic components within hepatic mass lesion have suggested that the lesions were metastatic tumors, primary cystic tumors such as biliary cystadenocarcinoma or cystic papillary cholangiocarcinoma. Although hepatic lesions can be well characterized by noninvasive imaging modalities, findings are often nonspecific. Even for cystic hepatic lesions a considerable diagnostic differential exists. The diagnosis of cystic hepatocellular carcinoma was difficult before the microscopic examination of the biopsy speciemen because of very rare. Then we report an unusual of cystic hepatocellular carcinoma without liver cirrhosis.
