Despite refinements in surgical techniques for liver transplantation, liver size disparity remains one of the most common problems in pediatric patients. Optimal liver graft size remains unknown and the volume of diseased liver in the recipient is not indicative of the volume (standard liver volume [LV]) optimal for the recipient's metabolic demands. To(More)
Data regarding the chronological changes in gastric mucosal cytokines in the different phases of Helicobacter pylori infection are unavailable. We examined Mongolian gerbils for up to 52 weeks after H. pylori (ATCC 43504) inoculation. Levels of mRNAs of mucosal cytokines (interleukin-1beta [IL-1beta], gamma interferon [IFN-gamma], IL-4, IL-6, and IL-10)(More)
Anorectal malignant melanoma (AMM) is a relatively rare disease. Because of its poor prognosis, the optimal surgical treatment for AMM is still controversial and difficult to determine. In this paper, we report five cases of AMM that have been treated by surgery and/or other methods at Shinshu University Hospital within the last decade. We also review the(More)
We investigated the effect of ethanol (a representative necrotizing agent) on gastritis induced by Helicobacter pylori infection in Mongolian gerbils. Seventy-eight gerbils were used. Four and 12 weeks after H. pylori inoculation, 30% ethanol was administered into the stomach. The stomachs were removed after 30 min, the intramucosal prostaglandin (PG) E2(More)
Rice extract has been shown to protect gastric mucosa from stress-induced damage. In this study, the antibiotic effect and the anti-inflammatory effect of orally administered aqueous rice extract on Helicobacter pylori infection and H. pylori-induced gastritis, respectively, in Mongolian gerbils were investigated. Fifty specific-pathogen-free male Mongolian(More)
BACKGROUND AND AIM The existence of other primary tumors during the treatment and management of gastric cancer (GC) is an important issue. The present study investigated the prevalence and management of synchronous colorectal neoplasms (CRN) in surgically treated GC patients. METHODS Of 381 surgically treated GC patients, 332 (87.1%) underwent colonoscopy(More)
Pancreatic adenocarcinoma is an aggressive human malignancy and is characterized by resistance to apoptosis. Recently, NADPH oxidase (Nox) 4-mediated generation of intracellular reactive oxygen species (ROS) was proposed to confer antiapoptotic activity and thus a growth advantage to pancreatic cancer cells. The signaling mechanism by which Nox4 transmits(More)
BACKGROUND This study was designed to examine the efficacy and compliance of S-1 for the patients with peritoneal metastasis of gastric cancer. METHODS Sixteen consecutive patients with peritoneal metastasis of gastric cancer were treated with S-1. Their survival was compared with that of the historical control group (25 patients). Thymidylate synthase,(More)
Reduced-size liver grafts from related donors may not be of an optimal size for adequate function in the recipient. Therefore, liver-graft regeneration is clinically important. We evaluated liver regeneration by liver-volume determinations with serial computed tomography scans in four recipients (aged 9 months to 12 years) and their donors (all fathers of(More)
