AIM A nationwide survey was performed to clarify the present state of fulminant hepatitis and late onset hepatic failure (LOHF) between 1998 and 2003 in Japan. METHODS Three hundred and sixteen, 318 and 64 patients, respectively, with acute and subacute types of fulminant hepatitis and LOHF, in which grade II or more severe hepatic encephalopathy occurred(More)
BACKGROUND/AIMS Inchin-ko-to (TJ-135) is an herbal medicine used in Japan for treatment of icteric patients with cirrhosis. Its efficacy as an anti-fibrogenic drug was evaluated in relation to stellate cell activation. METHODS/RESULTS Liver fibrosis was induced in rats by repeated injections of carbon tetrachloride (CCl4) or pig-serum. Oral administration(More)
The Japanese Society of Gastroenterology revised the evidence-based clinical practice guidelines for liver cirrhosis in 2015. Eighty-three clinical questions were selected, and a literature search was performed for the clinical questions with use of the MEDLINE, Cochrane, and Igaku Chuo Zasshi databases for the period between 1983 and June 2012.

Hepatocyte growth factor (HGF) has been shown to enhance albumin production as well as stimulate DNA synthesis in hepatocytes. The mode of action of HGF in exerting both effects is to be elucidated. We previously observed that hepatocyte proliferation occurred in normal rats given recombinant human HGF (rhHGF) intravenously. When rats received rhHGF(More)
Activated Kupffer cells and macrophages accumulate in necrotic areas in the liver. Osteopontin, an extracellular matrix with RGD sequence, has been shown to act as a chemokine that can induce monocyte migration. The possibility that osteopontin can play a role in infiltration of both cells into hepatic necrotic areas was investigated in rats. Northern blot(More)
Osteopontin is an extracellular matrix component that can act as a chemokine to induce macrophage migration. The significance of osteopontin in macrophage infiltration into the liver was examined in rats given heat-killed Propionibacterium acnes. In normal rats, osteopontin mRNA expression in the liver was mini-mal, determined by quantitative-competitive(More)
Human hepatocyte growth factor stimulates DNA synthesis by cultured rat hepatocytes. When human hepatocyte growth factor prepared from the culture medium of human embryonic lung fibroblasts was intravenously injected into normal rats and rats after 70% hepatectomy, it was detected in hepatocytes but not in nonparenchymal cells isolated 30 min after(More)
Serum human hepatocyte growth factor levels were measured using a newly developed enzyme-linked immunosorbent assay kit in patients with liver diseases. Serum human hepatocyte growth factor levels were increased in correlation with derangements of prothrombin time, total bilirubin and other parameters reflecting hepatocellular dysfunction in 112 patients(More)
The T-helper (Th)1 immune reaction is essential for the eradication of hepatitis C virus (HCV) during interferon (IFN) therapy in patients with chronic hepatitis C. Osteopontin is a cytokine crucial for the initiation of the Th1 response. Recently, we identified four single-nucleotide polymorphisms (SNPs) in the promoter region of the osteopontin gene(More)
Injection of a suspension of miriplatin into the hepatic artery has been employed for the treatment of hepatocellular carcinoma (HCC). The efficacy and safety of transcatheter arterial chemoembolization (TACE) using miriplatin were evaluated. A total of 236 patients with unresectable HCC received miriplatin administration through the hepatic artery,(More)
