PURPOSE: Down-regulation of E-cadherin is a hallmark of the epithelial-to-mesenchymal transition (EMT). EMT progression in cancer cells is associated with the loss of certain epithelial markers and the acquisition of a mesenchymal phenotype, as well as migratory activities. Cyclooxygenase-2 (COX-2) expression is associated with tumor invasion and metastasis in colon cancer. This study investigated the relationship between E-cadherin and COX-2 in colon cancer cells and human colon tumors. MATERIALS AND METHODS: Colon cancer cell lines and immunohistochemistry were used. RESULTS: E-cadherin expression was inversely related to the expressions of COX-2 and Snail in colon cancer cells. Ectopic expression of COX-2 or Snail reduced E-cadherin and induced a scattered, flattened phenotype with few intercellular contacts in colon cancer cells. Treatment of cancer cells with phorbol 12-myristate 13-acetate increased the expressions of COX-2 and Snail, decreased 15-hydroxyprostaglandin dehydrogenase expression, and increased the cells' motility. In addition, exposure to prostaglandin E2 increased Snail expression and cell motility, and decreased E-cadherin expression. Membranous E-cadherin expression was lower in adenomas and cancers than in the adjacent, non-neoplastic epithelium. In contrast, the expressions of Snail and COX-2 were higher in cancers than in normal tissues and adenomas. The expressions of COX-2 and Snail increased in areas with abnormal E-cadherin expression. Moreover, COX-2 expression was related to higher tumor stages and was significantly higher in nodal metastatic lesions than primary cancers. CONCLUSION: This study suggests that COX-2 may have a role in tumor metastasis via EMT.

Metabolic encephalopathy is a critical condition that can be challenging to diagnose. Imaging provides early clues to confirm clinical suspicions and plays an important role in the diagnosis, assessment of the response to therapy, and prognosis prediction. Diffusion-weighted imaging is a sensitive technique used to evaluate metabolic encephalopathy at an early stage.Metabolic encephalopathies often involve the deep regions of the gray matter because they have high energy requirements and are susceptible to metabolic disturbances. Understanding the imaging patterns of various metabolic encephalopathies can help narrow the differential diagnosis and improve the prognosis of patients by initiating proper treatment regimen early.

Various sequences have been developed for MRI to aid in the radiologic diagnosis. Among the various MR sequences, susceptibility-weighted imaging (SWI) is a high-spatial-resolution, threedimensional gradient-echo MR sequence, which is very sensitive in detecting deoxyhemoglobin, ferritin, hemosiderin, and bone minerals through local magnetic field distortion. In this regard, SWI has been used for the diagnosis and treatment of various neurologic disorders, and the improved image quality has enabled to acquire more useful information for radiologists.Here, we explain the principle of various signals on SWI arising in neurological disorders and provide a retrospective review of many cases of clinically or pathologically proven disease or components with distinctive imaging features of various neurological diseases. Additionally, we outline a short and condensed overview of principles of SWI in relation to neurological disorders and describe various cases with characteristic imaging features on SWI. There are many different types diseases involving the brain parenchyma, and they have distinct SWI features.SWI is an effective imaging tool that provides complementary information for the diagnosis of various diseases.

PURPOSE: Due to its size and locatin, the liver is frequently injured in abdominal trauma. Recently, nonoperative management for liver injuries has been extended due to the development CT imaging, intensive care units, and their equipment and techniques. Herein, patients with traumatic liver injury were analyzed to evaluate its treatment and prognostic factors. METHODS: From 2001, January to 2003, July, 65 patients at our facility were confirmed to have traumatic liver injury. The operative or nonoperative managements were decided on the basis of the systolic blood pressure if no peritoneal irritation sign was noted. If the systolic blood pressure was stable, or recovered to within the normal range following hydration and transfusion at the emergency room, patients were managed nonoperatively. Hemodynamically unstable patients were managed operatively. The data were analysed using the SPSS program (Chi-squared tests and logistic regression analyses). RESULTS: 48 patients were treated nonoperatively, with 3 mortalities. The overall mortality rate was 15.8%, but only 6.4% in the nonoperative management group, compared to 67% in operative management group. In a Multivariate analysis the systolic blood pressure was found to be a reliable factor in traumatic liver injury and the mentality and ISS (injury severity score) reliable in finding complications in the nonoperative management group. The mentality was found statistically reliable for determining mortality in the operative management group, with the exception for the systolic blood pressure. CONCLUSION: The systolic blood pressure was an important indicator when considering the treatment plan in traumatic liver injury. An extensive study will be required that incorporates both nonoperative and operative management groups.

Leiomyoma is the most common benign tumor of the esophagus, but it still occurs rarely as compared with the incidence of carcinoma in this area. Most of leiomyomas may manifest itself with unusual and inconsistent symptoms, and found incidentally during endoscopic or radiographic examination. Those who menifested symptoms are included as dysphagia and vague pain mostly. We experienced recently two cases with esophageal leiomyoma who underwent successful surgical resection and endoscopic enucleation, respectively.

A retrospective analysis of 36 cases of petrous pyramid fractures was studied clinically and radiographically during last 5 years. Of 503 patients with skull fractures admitted to the Inha University hospital, of which 7.1% involved the petrous pyramid. The most common mode of injury was a motor vehicle accident and the most common age group was the first decade. The anatomic location of fractures in the petrous pyramid were evaluated by high resolution computed tomography and it disclosed 20 longitudinal and 16 transverse fractures. The principal symptoms and signs, occurring alone or in combination, were a otologic problem, facial paralysis and CSF liquorrhea. The otologic problems were noted in almost every case. The facial palsy and CSF liquorrhea were present in 16 cases(36%) and 9 cases(25%), respectively. The anatomic type of fractures well corresponded to the principal symptoms and signs and the prognosis, the development rate of principal symptoms and signs of the transverse fracture was more higher and the prognosis of that was worse than the longitudinal fracture.

PURPOSE: Calcium-activated potassium channels(KCa) may be involved in the transient outward current of the first phase of cardiac action potential. But it is still not clear whether cardiac myocytes express any Kca. We try to identify here the types of Kc, expressed in rat caridac myocytes. METHODS: We isolated total heart RNA from 50 rats(Spague-Dawley) and performed reverse transcription-polymerase chain reaction(RT-PCR) using specifically designed synthetic oligonucleotide primer sets. From the pure culture of cardiac myocyte, Kc, gene expression was detected by Southern blot analysis. RESULTS: RT-PCR revealed expressions of BKca(large-conductance Kca, rSlo) and S&,(small-conductance Kca, rSK1). We prepared cardiac myocytes pure culture(>9596 pure myocyte) using pure culture technique. RT-PCR and Southern blot analysis of rat cardiac myocyte showed only rSK1-specific band, but no rSlo-specific was detected. CONCLUSION: The expressions of more than one type of Kca are detected from rat heart. A sub-type of SKcrSK1, was expressed in cardiac myocyte, while the main subunit of BKca(rSlo) was found in cells other than myocytes, most likely in the smooth muscle of cardiac blood vessels.
