A case of pigmented villonodular synovitis (giant cell tumor of the synovium) involving the vertebral column is presented. The tumor grew outside the dura and extended to the paravertebral connective tissue, causing sensory and motor disturbance indicative of spinal cord compression. This anatomic location is very rare for lesions of this type, and to our(More)
The localization of the enzymatic activity of non-specific esterase and endogenous peroxidase of the Langerhans' cells in murine epidermal sheets separated with EDTA was observed by means of light and electron microscopy. The Langerhans' cells exhibited non-specific esterase activity in the outer portion of the plasma membrane and endogenous peroxidase(More)
An autopsy case of massive renal hemorrhage in a 49-year-old male who had undergone maintenance hemodialysis for 8 years, is reported. No bleeding tendency had been noticed, and blood pressure had been reduced to within the normal range. Histological investigation with semiserial sections revealed that hemorrhage had occurred in four arteries, corresponding(More)
We investigated the effects on leukocyte adhesion to cultured human dermal microvascular endothelial (DMvE) cell by antibody mediated ligation of platelet/endothelial cell adhesion molecule-1 (PECAM-1) on neutrophils. Preincubation of neutrophils with anti-PECAM-1 antibody markedly enhanced their adhesion to DMvE cells, while the adhesion-increasing action(More)
AIMS To evaluate the ability of four rapid DNA extraction methods to provide DNA for the polymerase chain reaction (PCR) from routinely fixed, paraffin wax embedded archival tissues. METHODS Eighteen blocks of various tissues, 18 blocks of cervical cancer specimens, and nine blocks of B cell lymphomas were investigated. Both normal and biopsy specimen(More)
