The muscarinic cholinergic innervation of the rat gastric mucosa was investigated by localizing the muscarinic receptors using a tritiated muscarinic antagonist, pirenzepine. Radioautography was performed by freeze drying stomach tissue, which was then embedded in Epon and wet sectioned with ethylene glycol, and dry mounting on emulsion film by the(More)
We report a case of severe hypoglycemia and hepatic masses suspected to be an insulin-like growth factor-II (IGF-II)-producing hepatocellular carcinoma. A 62-year-old man presented with mental disorder in the night and early morning associated with extremely low blood sugar levels (less than 21 mg/dl). Computerized axial tomography and ultrasonography(More)
Rat Kupffer cell (KC)-mediated cytotoxicity against both the syngeneic hepatoma cell line AH70 and hepatocytes was evaluated by changes in mitochondrial function, and the possible role of ICAM-1/CD18 in the interaction between the cells was studied. Rhodamine 123 fluorescence, a marker of the mitochondrial membrane potential, decreased in AH70 cells after(More)
The metabolic changes in rat hepatoma cell line, AH70 cells, after coculturing with Kupffer cells were visualized using a silicon-intensified target camera and subsequent processing with a computer-assisted digital imaging processor. In cocultured tumor cells, nonactivated Kupffer cells reduced mitochondrial energization as indicated by the decrease in the(More)
The metabolic change in tumor cells (AH70, a rat hepatoma cell line) cocultured with isolated rat Kupffer cells were visualized and analyzed by a laser scanning confocal imaging system. When AH70 cells were cocultured with Kupffer cells, fluorescence intensity of rhodamine 123 (Rh123) decreased, indicating the reduction of mitochondrial function. The(More)
The case report of a 53-year-old woman with abdominal pain and bloody diarrhoea is described. Prior to the onset of symptoms the patient had taken royal jelly for 25 days. Colonoscopy revealed that the mucosa was haemorrhagic and oedematous throughout the 20 cm long sigmoid colon. Histopathologically, mucosal haemorrhage, oedema, and infiltration of(More)
The metabolic changes in a rat hepatoma cell line, AH70 cells, after co-culture with rat Kupffer cells (KC) were visualized and analysed using a fluorescence microscope equipped with a silicon intensified target camera and a laser scanning confocal microscopic system. Kupffer cells were isolated from male Wistar rats, and cultured without any stimuli. The(More)
The present study was designed to monitor the process for hepatoma cell injury induced by Kupffer cells. The non-activated Kupffer cells isolated from male Wistar rats reduced the mitochondrial membrane potential in the cocultured AH70 cells, which was indicated by the decreased rhodamine 123 (Rh123) fluorescence. Increased level of nitrite and nitrate in(More)
A 58-year-old male patient presented with abnormal discharge of 200 ml transparent fecal mucus. Irregular protuberance of the ascending colon into the adjacent ileocecal region was observed by colonofiberscopy, and a cystic lesion in the ileocecal region was suggested by computerized axial tomography. Pale yellowish semitransparent jellied substances were(More)
