متن کاملRelationship of substantia nigra echogenicity and motor function in elderly subjects.
BACKGROUND Patients with Parkinson's disease (PD) exhibit an increased echogenicity of the substantia nigra (SN) on transcranial sonography. Some healthy adults with the same echo characteristics showed a reduced 18fluorodopa uptake on PET, indicating a subclinical alteration of the nigrostriatal system. OBJECTIVES To determine whether the sonographic phenotype of hyperechogenic SN has any re...

متن کاملEchogenicity of the substantia nigra: association with increased iron content and marker for susceptibility to nigrostriatal injury.
BACKGROUND Patients with Parkinson disease characteristically exhibit an increased echogenicity of the substantia nigra (SN) on transcranial sonography, a new neuroimaging technique. The same echo feature of the SN can be identified in 9% of healthy adults. OBJECTIVE To evaluate the relevance of the echogenic SN in healthy adults. DESIGN In the first part of the study, 10 healthy subjects y...
متن کاملCulture of Substantia Nigra Neurons
Primary cultures of nigral tissue are widely used as a model system to assay effects of trophic and toxic agents on dopaminergic neurons. Cultured dopaminergic neurons have been successfully transplanted in animals and led to behavioral improvement in animal models of Parkinson’s disease. The success of these preclinical studies has encouraged investigators to begin clinical trials using transp...
