S-1 is a novel oral anticancer drug, composed of tegafur (FT), gimestat (CDHP) and otastat potassium (Oxo) in a molar ratio of 1:0.4:1, based on the biochemical modulation of 5-fluorouracil (5-FU). CDHP inhibits dihydropyrimidine dehydrogenase (DPD), an enzyme which degrades 5-FU, and maintains prolonged 5-FU concentrations in the blood and tumours. Oxo is(More)
A patient who suffered a recurring thrombosis over the last 15 yr has been investigated. The only abnormality found in this patient was a significantly depressed level of plasminogen activity in plasma. In spite of the depressed plasminogen activity, the patient was found to have a normal level of plasminogen antigen concentration. It was calculated that(More)
We analyzed the structure and the expression of Kunitz chymotrypsin inhibitor (WCI) genes in winged bean. WCI was encoded by a multigene family which comprised at least seven members. From their primary structures, four genes (WCI-2, WCI-3a, WCI-3b, and WCI-x) were expected to be functional ones and the other three (WCI-P1, WCI-P2, and WCI-P3) to be(More)
PURPOSE A phase II study of a combination chemotherapy regimen of cisplatin (CDDP) and irinotecan (CPT-11) was conducted to assess its efficacy and feasibility in patients with metastatic gastric cancer. PATIENTS AND METHODS Eligibility criteria included the following: (1) histologically proven gastric cancer with measurable metastatic lesions, (2)(More)
A multi-institutional collaborative late phase II study of irinotecan hydrochloride (CPT-11) was performed on patients with advanced gastric cancer. CPT-11 was administered as a 100 mg/m2 weekly intravenous infusion or as 150 mg/m2 fortnightly. Of 81 registered patients, 77 cases were eligible and 60 cases were evaluable for response. The overall response(More)
BACKGROUND Staphylococcus aureus sepsis is associated with significant myocardial dysfunction. Toll-like receptor 2 (TLR2) mediates the inflammatory response to S aureus and may trigger an innate immune response in the heart. We hypothesized that a TLR2 deficiency would attenuate S aureus-induced cardiac proinflammatory mediator production and the(More)
OBJECTIVE Although interest in diastolic heart failure is growing because of its clinical frequency, little is known about this type of heart failure. Our laboratory recently developed a diastolic heart failure model using Dahl salt-sensitive rat. In this model, gene expression of angiotensin-converting enzyme and endothelin (ET) system in the left(More)
BACKGROUND Matrix metalloproteinases (MMPs) are activated in dilated failing hearts, and angiotensin-converting enzyme (ACE) inhibition prevents left ventricular (LV) dilatation. However, it remains unclear whether activation of MMPs precedes or is secondary to LV remodeling, and an effect of ACE inhibition on MMPs is unknown. METHODS AND RESULTS Dahl(More)
5-Fluorouracil (5-FU) or a 5-FU derivative 1-(2-tetrahydrofuryl)-5-fluorouracil (FT) has been widely prescribed for patients with gastrointestinal cancer. However, the phosphorylation of 5-FU in the digestive tract causes gastrointestinal toxicities. 5-FU is also rapidly degraded to alpha-fluoro-beta-alanine after contact with dihydropyrimidine(More)
PURPOSE A phase II study was conducted to evaluate the antitumor effect and toxicity of CPT-11 in patients with metastatic colorectal cancer. PATIENTS AND METHODS From December 1989 to March 1991, 67 patients with metastatic colorectal cancer were enrolled in this study. Sixty-three patients were assessable for toxicity and response. Their median age was(More)
