PURPOSE: The inhibitory effect of TGFbeta1 on survivals of L1210 and anticancer drug- resistant L1210 sublines was investigated and the gene expression of TGFbeta1 in these cells was examined. MATERIALS AND METHODS: The survivals of L1210, adriamycin-resistant(L1210AdR), vincristine-resistant(L1210VcR) or cisplatin-resistant(L1210Cis) cells were measured by MTT assay after treatment of TGFbeta1. Northern analysis was performed for TGFbeta1 gene expression in L1210, L1210AdR, L1210VcR or L1210Cis. RESULTS: There was no different survival ratio between two groups, control and TGFbeta1(10 ng/ml) treated groups in L1210 cells. However, the survival ratio of L1210AdR was 59% in TGFbeta1 treated group for 96 hours. The survival ratio of L1210VcR was 61% for 96 hours in TGFbeta1 treated group. The survival ratio of L1210Cis was 40% for 96 hours in TGFbeta1 treated group. Expressions of TGFbeta1 gene in drug-resistant sublines were significantly decreased than that of L1210 cells. CONCLUSION: Growth of anticancer drug-resistant L1210 sublines were inhibited by TGFbeta1 but not in L1210 cells. So, it is suggested that TGFbeta1 gene expression may have a part in anticancer drug-resistance.

BACKGROUND: This study was conducted to compare the accuracy of computered tomography(CT) and sonography(US) in diagnosing acute appendicitis and to analyze the radiologic factors which influence the result. METHODS: We retrospectively studied the cases of 53 patients who were suspected of having appendicitis and who were examined by CT and US covered a three-year period. The final diagnosis was determined from the surgico-pathologic diagnosis and clinical follow-up for two months, as well as from the discharge diagnosis. RESULTS: Thirty-eight(38) patients had acute appendicitis; 15 patients did not. In the analysis, CT and US, respectively, revealed sensitivities of 89.5% and 73.7%, specificities of 93.3% and 60.0%, positive predictive values of 97.1% and 82.4%, negative predictive values of 77.8% and 47.4%. Among patients diagnosed with acute appendicitis, 10 patients were discordant in the US and the CT examinations; CT findings were correct in 8 and US findings in 2. Among non-appendicitis patients, 5 patients were discordant in the US and the CT examinations; CT was correct in 5 and US in 0. Nighteen(19) patients had complications such as an abscess or a perforation. Among these patients, the degree and the extent of the complication were accurately evaluated by CT in 15 patients and by US in 5 patients. CONCLUSION: CT is more accurate than US in diagnosing and excluding acute appendicitis. The use of CT will substantially decrease unnecessary laparotomies and post-operation complications.

Pulmonary thrombo-embolism in operating room is one of the important cause of morbidity and mortality in patients undergoing femur neck fracture surgery. However, the diagnosis of pulmonary thromboembolism may not be easy because sudden shock can have many different causes (e.g. myocardial infarction, hypovolemia, pneumothorax, non-cardiogenic pulmonary edema, pulmonary thrombo- embolism) and specialized diagnostic tools are not readily available in the operating room. Rapid and accurate diagnosis of pulmonary thromboembolism is very important in outcome of patients. We report a case in which pulmonary thromboembolism under spinal anesthesia occured just before the beginning of operation.

Mucin-hypersecreting biliary neoplasm excretes excessive mucin that fills the biliary tree and results in marked dilatation of the bile ducts and obstructive jaundice. In these neoplasm, the mucin produced by the tumor rather than the tumor itself plays an important role in clinical course and radiologic patterns. The purpose of this paper is to report characteristic radiologic patterns of mucin-hypersecreting biliary neoplasms in two cases. These neoplasms were characterized by not only multilocular cystic hepatic mass or extra-hepatic bile duct mass resulting in marked biliary dilatation distal to the mass on US or CT, but also change of shape and extent of amorphous filling defects in the markedly dilated bile duct on serial cholangiograms.
