OBJECTIVE The molecular mechanism of preconditioning the heart by repeated ischaemia was investigated by examining the expression of stress related and antioxidative genes and proteins. METHODS Isolated buffer-perfused rat hearts were made ischaemic for 5 min followed by 10 min of reperfusion (1 x PC). Another group of experiments was performed by(More)
Repeated regional ischemia of short duration followed by reperfusion leads to preconditioning of the myocardium. Left anterior descending coronary artery (LAD) occlusion was applied for 5 minutes and then released for 10 minutes. This was repeated four times by using an intact pig model. LAD occlusion was then continuously applied for 1 hour. Myocardial(More)
The cardioprotective effects of a novel antiinflammatory drug, ONO-3144 (ONO), on ischemic-reperfused myocardium were investigated using an in situ pig heart model. Heart was subjected to 2 h of regional ischemia, with the final 1 h having superimposed global cardioplegic arrest followed by 1 h of reperfusion. ONO (20 microM) was administered after the(More)
The amino acids aspartate and glutamate, in combination, were evaluated as a means of reducing infarct size and improving cardiac function during reperfusion in an intact pig having an acute anteroseptal infarct. Three groups of 6 pigs each were randomly studied in a blinded manner: control (no amino acids), aspartate/glutamate 3 mmol/L, and(More)
Nonalcoholic steatohepatitis (NASH) is an inflammatory form of nonalcoholic fatty liver disease that progresses to liver cirrhosis. It is still unknown how only limited patients with fatty liver develop NASH. Tumor necrosis factor (TNF)-α is one of the key molecules in initiating the vicious circle of inflammations. Nardilysin (N-arginine dibasic(More)
A 79-year-old woman with pneumobilia and liver dysfunction was admitted to our hospital. ERCP and gastrointestinal endoscopy revealed choledochal stones and a cholecystogastric fistula at the greater curvature of the gastric antrum. The risk of cholecystectomy and fistulectomy appeared to be extremely high for this patient because of her advanced age and(More)
A 48-year-old man was admitted to our hospital because of eosinophilia and liver dysfunction. Initial abdominal CT and MRI (MRCP) finding showed almost normal liver and bile duct. Liver biopsy demonstrated mild portal infiltration of lymphocytes and eosinophils. Definitive diagnosis was difficult, but we suspected autoimmune disease. Oral steroid(More)
Acetaminophen (paracetamol), a widely used antipyretic/analgesic, is a well-known agent causing acute hepatic injury. Whereas most cases are caused by its intrinsic hepatotoxicity, idiosyncratic hepatitis by the allergic mechanism is extremely rare. We herein report a case of late-onset acetaminophen-induced allergic hepatitis with progression to(More)
