    Notizen: Abstract We have studied brain tissues from three patients with corticobasal degeneration (CBD) histologically, ultrastructurally and immunohistochemically. Ballooned neurons in the cerebral cortex and severe degeneration of the substantia nigra were observed in them all and weakly basophilic neurofibrillary tangles (NFTs) were distributed widely in the basal ganglia and brain stem. Ultrastructural examination demonstrated that the NFTs comprised characteristic 15-nm-wide straight tubules, which showed positive immunohistochemical staining with an antibody against tau, but not ubiquitin. Tau-immunoreactive neuronal cell bodies without NFTs also were found in the cerebral cortex and subcortical nuclei, predominantly in the brain stem, and the greatest number of tau-positive glial inclusions occurred in the cerebral gray and white matter of the pre- and post-central gyri. These inclusions comprised tubular structures with diameters of about 15 nm and were localized in the oligodendroglial cellular cytoplasm and processes. These findings indicate that there is a close cytoskeletal pathological relationship between CBD and progressive supranuclear palsy.

    Notizen: Abstract We report a 62-year-old man with sporadic motor neuron disease (MND) of 52 months’ duration with progressive sensory disturbance and high cerebrospinal fluid protein content. Neuropathologically, both the upper and lower motor neuron systems were severely affected, and light and electron microscopy revealed Bunina bodies and skein-like inclusions, which are characteristic of amyotrophic lateral sclerosis, in the remaining anterior horn cells. Moreover, there was severe degeneration without inflammatory infiltrates in the spinal posterior columns, spinal ganglia, and peripheral sensory nerves. These findings suggest that this case may be an unusual variant of sporadic MND with severe somatic sensory system involvement.
