In vasogenic brain edema, the neurotoxicity of extravasated serum components may contribute to neuronal damage. In the hippocampal CA1 sector and striatum, the neurotoxicity of serum was investigated. Rat serum was prepared as follows: Serum-1: whole serum, Serum-2: ultrafiltrated through a membrane with cut-off at molecular weight (MW) 100,000. Serum-3:(More)
During blood-brain barrier opening serum IgG could be extravasated. The function of intraparenchymal IgG, however, is unknown. Its biological effects in the acute phase were currently investigated. From rat autoserum IgG was purified and injected into the cortex. Similarly, IgG-Fab fragment was prepared and administered likewise. As for the control group,(More)

We herein report a case of anaplastic carcinoma of the pancreas arising in an intraductal papillary mucinous neoplasm (IPMN). A 68-year-old Japanese woman was admitted to our hospital complaining of fatigue. Computed tomography revealed an irregular mass in the pancreatic head, which displayed high-signal intensity on diffusion-weighted magnetic resonance(More)
Radiological, histological and molecular findings in an uncommon adult case of cerebellar medulloblastoma suggested an external granular cell precursor origin. This 19-year-old woman had a 1-month history of progressively worsening headache. Neuroimaging studies demonstrated a homogeneously enhanced well-circumscribed mass lesion in the right cerebellar(More)
We developed a model by which the transvascular removal of unnecessary substances in brain edema fluid could be measured quantitatively and chronologically. Brain stab wounds were produced in Wistar rats by insertion of paired microdialysis probes in the unilateral caudatoputamen. Homovanillic acid (HVA) was administered by microdialysis from one probe, and(More)
Experimental cerebral ischaemia was produced by microembolization in rats. HRP (horseradish peroxidase) was then injected into the cerebral cortex and the extracellular fluid dynamics were observed. In the control group, there was a basic pattern in the migration of the tracer. In the ischaemic group, a 'dense tracer distribution around the focus' was found(More)
