title: [A comparative immunohistochemical study of ubiquitin-positive skein-like inclusions in anterior horn neurons in subgroups of adult-onset motor neuron diseases].
abstract: This study investigated the expression of ubiquitin in anterior horn cells of various subgroups of adult-onset motor neuron diseases (MNDs). Ubiquitin-positive skein-like inclusions (SLIs) were found in all 11 cases of sporadic amyotrophic lateral sclerosis (ALS) patients, two patients with lower MND, 3 sporadic cases of ALS with dementia, 3 sporadic ALS cases with long-term use of respirators, and two cases of sporadic ALS with Lewy body-like hyaline inclusions. This result suggests that a similar pathomechanism is involved in the degeneration of the lower motor neurons in these subgroups. SLIs were not detected in two cases of adult-onset MND with basophilic inclusions. This may indicate that adult-onset MND with basophilic inclusions is a distinct nosological entity of classical ALS and some relationship to juvenile ALS with basophilic inclusions is suggested.
