Regenerating areas of human lungs in pulmonary fibrosis were observed electron microscopically, and peroxidatic activity of catalase in lung peroxisomes were demonstrated cytochemically. Proliferation of Type II cells was prominent there, and some of the cells extended their cytoplasms to cover the denuded basement membrane. Unusual intermediate cells(More)
This report describes anomalous cases having the so-called gastro-lienal and the hepato-mesenteric trunks instead of the celiac and superior mesenteric arteries. These anomalous cases were divided into 4 types and 6 classes according to difference of running form of the hepatic artery as follows. Type I: This hepatic artery arose from an unusual(More)
The preventive effects of acidic xylooligosaccharide prepared from xylan of corncobs and related sugars on stress-induced gastric inflammation in mice were investigated. Oral administration of acidic xylooligosaccharide and hydrocortisone at doses of 100 and 200 mg/kg body weight significantly reduced the number of bleeding points in the gastric mucosa of(More)
I-123 iodoamphetamine (IMP) and Ga-67 scintigraphy of malignant melanoma were performed to compare the accumulation of these tracers regarding tumor diameter to determine the site of I-123 IMP accumulation and to evaluate the use of I-123 IMP and Ga-67 in postoperative follow-up. The studies involved 44 patients with a definite diagnosis of malignant(More)
The present report describes the dissection of an 81 year-old Japanese female cadaver in the Kanazawa Medical University in which the celiac trunk was not present, that is, the left gastric, the splenic and the common hepatic arteries arose independently from the abdominal aorta in that order. In this case, the left gastric artery arose from the front wall(More)
To elucidate the synaptic transmission in the neural system, we have been developing fundamental studies for intracellular signaling. For clinical application of carbon-11 labeled diacylglycerol (1-[1-11C]butyryl-2-palmitoyl-rac-glycerol: 11C-DAG) using positron emission computed tomography (PET), we evaluated the quality and the safety of 11C-DAG as the(More)
