A multi-institute, hospital-based, case-control study on pancreatic cancer was carried out to examine its association with preceding diseases, cigarette smoking, alcohol drinking and dietary factors. Analyses were based on 124 newly diagnosed exocrine pancreatic cancer cases and sex-, age- and institute-matched hospital controls in seven hospitals in Japan.(More)
The tumor-killing activity of radiotherapy and chemotherapy for cancer is closely associated with the production of active oxygen, and the relation between therapeutic resistance and active oxygen scavengers produced by the tumor itself is gaining more attention. It is considered that manganese superoxide dismutase (MnSOD) protects host cells from oxidative(More)
BACKGROUND/AIMS Osteopontin (OPN) is significantly overexpressed in a variety of malignancies. However, little is known concerning the significance of OPN expression in human cancers. Thus, the aim of this study was to determine the relationship between the degree of OPN expression, the proliferative activity of cancer cells, and the clinicopathological(More)
Mucin glycoproteins from the gallbladder epithelium are thought to contribute to the matrix or nucleus of gallstones and other biomineralization systems. The involved acidic glycoproteins have been reported in bile and gallstones. In addition, osteopontin (Opn) is a noncollagenous acidic bone matrix glycoprotein that possesses calcium-binding properties. To(More)
The effect of taxol, which is a microtubule stabilizer, was examined in a model of acute edematous pancreatitis induced in rat by the administration of caerulein. Prophylactic administration of taxol ameliorated inhibition of pancreatic secretion, increased level of serum amylase, pancreatic edema, and histological alterations in this model.(More)
The purpose of this study was to examine whether the increased sensitivity of cancer cells to adriamycin (ADM), which is known to produce superoxide radicals, was brought through suppressed manganese superoxide disumutase (MnSOD) expression in the presence of transforming growth factor beta1 (TGFbeta1). T.T., MKN28, and MKN45 cell lines were treated with(More)
BACKGROUND A prospective, randomized study was performed to determine whether gemcitabine infusion at a low dose (250 mg/m2) is comparable or superior to the standard-dose infusion (1000 mg/m2) in terms of the survival period, clinical benefit, and frequency of adverse effects in patients with advanced pancreatic adenocarcinoma. METHODS Twenty-five(More)
At a number of points in the current procedures of islet isolation and islet culture after the harvesting of donor pancreata, microorganisms could potentially infect the islet preparation. Furthermore, the use of islets from multiple donors can compound the risks of contamination of individual recipients. Acidic oxidative potential water (also termed(More)
After the experimental and phase one studies of our so-called "artificial blood," Fluosol-DA (20%), an emulsified mixture of perfluorodecalin and perfluorotripropylamine, were successfully completed, phase two and three clinical studies were carried out on 186 patients in Japan. The initial dose was 20 ml/Kg body weight (BW), and additional 10 ml/Kg BW(More)
Manganese superoxide dismutase (Mn-SOD), a mitochondrial enzyme, is a cytokine-regulated acute-phase protein that protects cells from free radicals. The current investigations examined the in vivo regulation of the expression of Mn-SOD mRNA and tumor necrosis factor alpha (TNFalpha) mRNA in gastric carcinoma tissue. The expression of these transcripts in(More)
