Bladder tumors initially may be diagnosed by excretory urography. In this study, 60 excretory urogramsincluding 40 cases of biopsy proved blaadder tumor and 20 cases of cystoscopically normal bladder were analyzed.Five experienced readers reviewed five radiographs of each case. The results were as follows: 1. Male to remaleratio was 5.7:1, and the highest incidence of age distribution was between 60 and 69 year with 48%. 2. The tumorswere chiefly located in lateral wall of bladder. (67%) 3. Among 40 cases, pathologic diagnosis was as follows:Transitional cell ca. 39 cases, and squamous cell ca. lcase. 4. The I.V.P. finding showed 82% of normal upperurinary tract, 13% of hydronephrosis, 5% of non-visualization, and 58% of filling defect in bladder. 5. Originalinterpretation of urogram was as follows: Of 40 cases with bladder ca., 45% as positive, 13% as suspicious, and38% as negative. Of 20 cases with normal, 95% as negative, and 5% as positive. 6. Analysis by this study was asfollows: Accuracy 68%, sensitivity 62%, specificity 80%, false positive rate 38%, and false negative rate 20%. 7.25 min A-P radiograph was most valuable projection and oblique projection did not significantly increasesensitivity.

So-called, the double channel pylorus has been, relatively rarely, reported through out the world. All reported cases were almostly those of gastroduodenal fistula as a complication of peptic ulcer disease. The congenital forms of double pylorus were reported even more rarely. We found three cases of double channel pylorus in 25,000 cases endoscopy done at our unit. All those three cases were thought to be acqired form endoscopically, radiographically and histologically. One of those was undergone to operative resection because of uncontrollable bleeding and the others were on medical theraphy with satisfaction.

We have analyzed two (BclI and XbaI) intragenic restriction fragment length polymorphisms (RFLPs) and St14 (DXS52) variable number of tandem repeats (VNTR) by rapid PCR method in 97 unrelated normal subjects. The incidences for positive Bc1I and XbaI polymorphic sites in the Koreans were 81% and 72%, respectively, which were higher than other ethnic groups but similar to that reported in the Chinese or Japanese, giving the heterozygosity rate of 0.32 and 0.40, respectively. The amplified allele size was 880 bp with no other polymorphism in the analysis of St14 (DXS52) VNTR. This finding should be taken into account in the planning of a prenatal diagnosis program for ethnic Koreans

OBJECTIVE: A 10-year retrospective lumboperitoneal(LP) shunt surgery was reviewed in order to verify the several prognostic factors including the etiology, the findings of brain computed tomography(CT) and/or magnetic resonance imaging(MRI), and the effect of lumbar drainage which have been implicated in the result of LP shunt. PATIENTS AND MEHTODS: A series of 32 patients who underwent LP shunt surgery between March 1988 and May 1998 for the management of communicating hydrocephalus was reviewed. RESULTS: The etiology of communicating hydrocephalus was subarachnoid hemorrhage(SAH) in 19 cases(59.4%), head trauma in 10 cases(31.2%), intracerebral hemorrhage in 2 cases(6.3%), meningitis in 1 case(3.1%), tumor in 1 case(3.1%), and idiopathic in 2 cases(6.3%). The mean follow-up period was 1.2 years(range, 2 week to 8.5 year). Among them, twenty four patients(75%) were clinically improved after shunt operation. The result of LP shunt was not related to the etiologies and many findings of brain CT/MRI such as ventricular index, Evan's index, periventricular low density, obliteration of cerebral sulci and cortical atrophy. However, the result of LP shunt was significantly related to the effect of preoperative lumbar drainage(p=0.0184). CONCLUSION: This result suggests that the effect of preoperative lumbar drainage has a significant role in predicting the result of LP shunt in patients with communicating hydrocephalus.

INTRODUCTION: Bone resorption is a unique function of osteoclasts. Osteoclasts are a specialized macrophage polykaryon whose differentiation is regulated principally by macrophage colony-stimulating factors, receptor activator of nuclear factor kappaB ligand (RANK) ligand, osteoprotegerin (OPG), and interleukins (IL). Reflecting the integrin-mediated signals, osteoclasts develop a specialized cytoskeleton that allows it to establish an isolated micro-environment between itself and the bone, wherein matrix degradation occurs by a process involving proton transport. The levels of IL-1, IL-6, OPG, and prostaglandin E2 (PGE2) expression were evaluated to study the correlations between dental implant teeth and the adjacent teeth. MATERIALS AND METHODS: The exudate of the gingival crevice acquired from dental implants, adjacent teeth, opposite teeth and contralateral teeth of 24 patients. RESULTS: 1. The levels of IL-1, IL-6, OPG and PGE2 expression in dental implant teeth were higher than those of the contralateral teeth. 2. IL-1 revealed a higher expression level in the adjacent teeth than in dental implant teeth. 3. The dental implant teeth and adjacent teeth did not show a remarkable difference in the level of IL-1 expression. 4. All the other cytokines were strongly expressed in the dental implant compared to the adjacent teeth. CONCLUSION: These results suggest that there might be close correlation between dental implant teeth and adjacent teeth in terms of the expressions of cytokines that affect the development and regulation of osteoclasts.

Deep vein thrombosis is recognized as a common complication in surgical patients in western countries especially in patients with high risk factors. The purposes of this study were to detect leg DVTs in early postoperative period by non-invasive surveillance and to analyze the risk factors of DVT. One hundred seventy one patients who underwent major operations ( 67 curative resection of colorectal cancer, 64 total hip replacement, 38 femur operations for fracture, and 2 colon resections for benign colon disease) were included for the prospective surveillance of leg DVT within 2 weeks after the operations. For the surveillance of leg DVT, strain gauge plethysmography(SPG) and Duplex scanning of both legs were completed for all patients except 10 patients. These 10 patients were examined in only one leg. The patients with past history of leg DVT or under prophylactic anticoagulant therapy were excluded from this study. To determine the risk factors related with leg DVT formation, age and sex of the patients, indication of surgery or surgical procedures, duration of operation, position during the operation, duration of postoperative immobilization, and preoperative serum level of antithrombin III(AT-III) were analyzed using Chi-square test. After performing SPG of 342 legs, 38 legs showed abnormal on venous outflow/venous capacitance discriminant line chart, and 13 legs of 12 patients showed the finding(s) suggesting DVT on duplex scanning. Among the patients with abnormal duplex findings, 7 limbs(53.8%) were symptomatic, but the remaining 6 legs were silent. In 6(15.8%) patients of 36 femur operations, 3(4.7%) of 64 total hip replacements and 3(4.5%) of 67 curative resections of colorectal cancer developed DVT by duplex scanning in the iliac(5), femoral-popliteal(6), and isolated calf(2) veins. After analyzing the risk factors, we could not find any statistically significant(p<0.05) factor related with leg DVT.

PURPOSE: An arsenical compound, As2O3, has been reported to be effective for treating acute leukemia and inducing apoptosis in many different tumor cells. In this study, the ability of As4O6 to suppress cell growth and induce gene expression patterns was tested using a cDNA microarray in HPV16 immortalized cervical carcinoma cells, SiHa cells, along with As2O3. MATERIALS AND METHODS: A novel arsenical compound, As4O6, was designed and its ability to induce cell growth inhibition as well as gene expression profiles along with As2O3 in HPV16 infected SiHa cervical cancer cells was compared. Both As2O3 and As4O6 induced apoptosis in SiHa cells, as determined by DNA ladder formation. To further compare the gene expression profiles between these two drugs, a 384 cDNA microarray system was employed. Also, the gene expression profiles were classified into the Gene Ontology (GO) to investigate apoptosis-related cellular processes. RESULTS: As4O6 was more effective i suppressing the growth of SiHa cells in vitro compared to As2O3. In the case of treatment with As2O3, 41 genes were up- or down- regulated at least 2 fold compared to non-treatment. However, 65 genes were up- or down-regulated by As4O6 treatment. In particular, 27 genes were commonly regulated by both arsenic compounds. Also, the GO analysis indicated that down-regulation of cell-regulatory functions, such as cell cycle, protein kinase activity and DNA repair, induced anti-tumor effect. CONCLUSION: These data support that As4O6 could be more effective than As2O3 in inhibiting the growth of HPV16 infected cervical cancer cells. This appears to be mediated through a unique, but overlapping regulatory mechanism(s), suggesting that the regulated genes and cellular processes could be further used as a new potential drug approach for treating cervical cancer in clinical settings.

PURPOSE: This study was performed to evaluate three-dimensional positional change of the condyle using 3D CT after bilateral sagittal split ramus osteotomy (BSSRO) in skeletal class III patients. PATIENTS AND METHODS: Nine patients who underwent BSSRO for mandibular set-back in skeletal class III malocclusion without facial asymmetry were examined. Miniplates were used for the fixation after BSSRO. 3-D CT was taken before, immediately after, and 6 months after undergoing BSSRO. After creating 3D-CT images using V-works 4.0(TM) program, axial plane, coronal plane, < sagittal plane were configured. Three dimensional positional change, from each plane to the condyle, of the nine patients was measured before, immediately after, and 6 months after undergoing BSSRO. RESULTS: 1. The mean value of mandibular set-back for nine mandibular prognathism patients was 7.36 mm (+/- 2.42 mm). 2. In the axial view, condyle is rotated inward immediately after BSSRO (p < 0.05), comparing with preoperative but outward 6 months after BSSRO comparing with postoperative (p < 0.05). 3. In the axial view, condyle is moved laterally immediately after BSSRO (p < 0.05), comparing with preoperative but regressed 6 months after BSSRO comparing with preoperative (p < 0.05). 4. In the frontal < coronal view, there is changed immediately after and 6 months after BSSRO, comparing with preoperative but no statistical difference. CONCLUSION: These results indicate that three-dimensional positional change of the condyle in skeletal class III patients is observed lateral displacement < inward rotation immediate after BSSRO, but the condyle in 6 months after BSSRO tends to regress to preoperative position.

PURPOSE: Recommended dietary allowance of vitamin C was determined on the basis of preventing the scurvy without considerations of the important function of the vitamin C as a first line antioxidant. So we measured the whole blood and plasma vitamin C concentrations of the contemporay healthy elementary school children in Chinju for the establishment of the optimal daily vitamin C requirment in the elementary school children. METHODS: Whole blood and plasma vitamin C concentrations were measured by the 2,4-dinitrophenylhydrazine method in 338 children from the 1st to the 6th grade of one elementary school in Chinju. RESULTS: Whole blood and plasma vitamin C concentrations were 1.36+/-0.34mg/dL and 1.07+/-0.33mg/dL respectively. There existed an close relationship between whole blood and plasma vitamin C concentrations (r=0.77, p=0.0001). Whole blood vitamin C concentration decreased as the age became older (r=-0.22 p=0.0001), but plasma vitamin C concentration did not change. There were no sex differences in the whole blood and plasma vitamin C concentrations except in the 3rd grade (p<0.05). Twenty-three of 338 elementary school children (6.8%) had the plasma vitamin C concentration less than 0.6mg/dL. CONCLUSIONS: We produced the blood and plasma vitamin C concentrations of the contemporay elementary school children in Chinju. These values were not satisfactory in consideration of the importance of the childhood health.
