Arsenic is a well-documented human carcinogen, and contamination with this heavy metal is of global concern, presenting a major issue in environmental health. However, the mechanism by which arsenic induces cancer is unknown, in large part due to the lack of an appropriate animal model. In the present set of experiments, we focused on dimethylarsinic acid(More)
BACKGROUND Several noninvasive tests have been proposed to predict cirrhosis in patients with chronic hepatitis C, but not in patients with non-alcoholic steatohepatitis (NASH). We assessed whether noninvasive laboratory tests designed to predict the risk of cirrhosis in patients with chronic hepatitis C virus (HCV) infection could be used in patients with(More)
Cytoglobin (CYGB) is ubiquitously expressed in the cytoplasm of fibroblastic cells in many organs, including hepatic stellate cells. As yet, there is no specific marker with which to distinguish stellate cells from myofibroblasts in the human liver. To investigate whether CYGB can be utilized to distinguish hepatic stellate cells from myofibroblasts in(More)
Hepatocellular carcinoma (HCC) develops several years after the eradication of hepatitis C virus (HCV) by interferon therapy. Risk factors for the development of HCC are only partly understood. To elucidate the role of occult hepatitis B virus (HBV) infection in hepatocarcinogenesis in patients with sustained virologic response, the prevalences of(More)
AIM The association between sarcopenia and nutritional status is thought to be an important problem in patients with cirrhosis. In this study, we investigated whether nutritional factors were related to sarcopenia in patients with liver cirrhosis. METHODS The subjects were 50 patients with cirrhosis aged 41 years or older. In this study, the subjects were(More)
AIM   The usefulness of transient elastography remains to be validated in chronic hepatitis B, particularly as a tool for monitoring the degree of liver fibrosis during treatment. METHODS   The subjects were 50 patients with chronic hepatitis B virus infection. Liver biopsy was performed in 38 patients, and in 12 patients with platelet counts of 50 ×(More)
BACKGROUND Although histopathological examination by "invasive" liver biopsy remains the gold standard for evaluating disease progression in chronic liver disease, noninvasive tools have appeared and have led to great progress in diagnosing the stage of hepatic fibrosis. The aim of this study was to assess the value of real-time tissue elastography, using(More)
BACKGROUND/AIMS Although Fas expression has been reported in liver with chronic viral hepatitis and primary biliary cirrhosis, little is known about Fas expression and apoptosis in type-1 autoimmune hepatitis. The aim of this study was to investigate whether the expression of Fas and apoptosis are found in liver with autoimmune hepatitis. The relationship(More)
A 37-year-old woman was admitted to a hospital with jaundice. Within a couple of weeks, her liver function improved with only symptomatic therapy. About 30 to 60 days before admission, she had taken a herbal medicine, bofu-tsu-sho-san. A diagnosis of drug-induced liver injury was made according to the diagnostic scale proposed at the Digestive Disease(More)
BACKGROUND AND AIM Thiopurine S-methyltransferase (TPMT) genotypes or phenotypes may be a predictive factor for azathioprine-induced toxicities. We investigated the genotypic status of TPMT to evaluate the risk of azathioprine-related adverse effects in Japanese patients with different liver diseases, including autoimmune hepatitis (AIH).
