Interleukin-1B and IL-1 receptor antagonist gene polymorphisms are associated with an increased risk of gastric cancer (GC) in Caucasian populations. However, recent studies could not find any association between IL-1B-511T polymorphism and the risk of GC in Asians. We tested for an association between IL-1 loci polymorphisms with increased gastric mucosal(More)
BACKGROUND/AIMS Cigarette smoking is the most significant environmental factor identified in inflammatory bowel disease (IBD). Smoking has a beneficial effect on ulcerative colitis (UC) patients. In contrast, Crohn's disease (CD) is associated with smoking, and a detrimental effect of smoking on the course of CD has been demonstrated. The aim of this study(More)
The rat hepatocytes were immortalized using a temperature-sensitive mutant of SV40 large T antigen (tsT) to develop as a possible substitute for primary hepatocytes. Four rat hepatocyte lines that have been developed and maintained more than passage 50, were characterized for their cellular morphology, T antigen and p53 expression, chromosomes,(More)
A positive family history is an increased risk factor for gastric cancer within family members, and one of the possible causes of this is the intrafamilial clustering of Helicobacter pylori infection. Our study examined the prevalence of H. pylori infection, serum antibodies to CagA and VacA and atrophic gastritis and/or intestinal metaplasia in the(More)
Chronic hepatitis B virus (HBV) infection is the most common cause of hepatocellular carcinoma (HCC) worldwide. This study investigated the antineoplastic effects of intrinsic and extrinsic peroxisome proliferator-activated receptor gamma (PPARgamma) ligands against HBV-associated HCC cells in vitro. Four cell lines that were established from patients with(More)
Lung cancer metastases can occur in almost any organ. However, metastasis of small cell lung cancer to the pancreas is rare. Moreover, not all cases present with clinically diagnosed pancreatitis. We recently treated a patient with small cell lung carcinoma that invaded the pancreatic duct causing acute pancreatitis. Generally, the treatment for(More)
OBJECTIVES:Although symptomatic propylthiouracil (PTU)-induced hepatic injury is known to be rare, there have been few reports about its exact incidence in patients with hyperthyroidism. We tried to evaluate its incidence in a single center and its clinical course.METHODS:Medical records of 912 hyperthyroid patients who had been diagnosed between March 1990(More)
BACKGROUND/AIMS Patients with hepatocellular carcinoma (HCC) may manifest paraneoplastic syndromes such as hypercholesterolemia, hypoglycemia, hypercalcemia and erythrocytosis. This study was aimed at evaluating the incidence and clinical significance of paraneoplastic syndromes in Korean HCC patients. METHODS The medical records of 165 HCC patients who(More)
BACKGROUND/AIMS Saccharomyces boulardii (S. boulardii) has been reported to be beneficial in the treatment of inflammatory bowel disease, however, little is known about its mechanism of action. Peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is recently found to regulate inflammation in intestinal epithelial cells. We hypothesized that the(More)
A santorinicele is defined as a focal cystic dilatation of the terminal portion of the dorsal pancreatic duct at the minor papilla. Most cases reported previously were associated with pancreas divisum and a santorinicele without pancreas divisum is known to be rare. We recently experienced a typical case of a santorinicele without pancreas divisum in a(More)
