The purpose of this study was to assess systematically morphology of peripheral nerves from patients with human immunodeficiency virus infection (acquired immunodeficiency syndrome [AIDS] and AIDS-related complex) examined at autopsy. Sural nerve specimens were taken from 25 patients (mean age 44 years) and evaluated by routine procedures used in our(More)
We have investigated the mechanism of nitric oxide-induced damage in glial cells. Genomic DNA isolated from astrocytes and microglia, treated for 18 h with varying concentrations of a nitric oxide donor, was analysed by electrophoresis. No DNA damage was evident. Oligodendrocytes, treated with 2 mM nitric oxide for 3-48 h, showed single stranded breaks at(More)
Specimens of cerebral cortex were prepared for electron microscopy from cortical resections performed for the treatment of intractable seizures in four cases of hemimegalencephaly (HME). Morphometric analyses were performed to determine mean cortical thickness, the numerical density of synapses (NV, contacts per mm3) and the number of synapses in a column(More)
A case is reported of intraventricular neurocytoma that had characteristic light microscopic findings of neurocytoma with prominent intracytoplasmic concentric lamellar structures mimicking myelin sheaths. On routine H&E-stained sections, this tumor showed intracytoplasmic vesicular bleb-like structures having eosinophilic cores that were consistent with(More)
