Abstract:
Objective To investigate the oligodendroglial cytoplasmic inclusion (OCI) in the central nervous system of multiple system atrophy (MSA) and to evaluate its roles in pathologic diagnosis of MSA.Methods Modified Gallyas Braak staining was used to investigate tissue samples of the brain and the spinal cord of 4 cases with MSA, which were previously diagnosed by clinical and routine pathologic methods. Eight cases with motor neuron disease and 6 cases without nervous system disease were used for control study.Results OCIs were demonstrated by Gallyas barrak method in the white matter of the brain and the spinal cord of 3 cases with MSA. They look like sickle , semilunar , and flame shaped. Their main distributions were transverse fibers of the basis pontine, the white matter of the cerebellum, striatopallidal fibers and lateral column of the spinal cord. While OCIs were not found in the brain and the spinal cord of one case without typical clinical features and pathologic findings. Nor did all of the control cases.Conclusions OCIs may be regarded as pathologic marker of the sporadic forms of MSA. It also suggests that OCIs are related to degenerative process of myelinated fibers in MSA.
