The binding of gallium (Ga) to transferrin (Tf) was studied in plasma from control patients, in patients with untreated Parkinson's disease (PD) and in patients with PD treated either with levodopa (L-dopa) alone or in combination with selegiline. Mean percentage Ga-Tf binding was significantly reduced in untreated and treated PD compared with controls. Binding, however, was significantly greater in treated than in untreated patients. There was no difference in binding between patients treated with L-dopa alone and those treated with L-dopa and selegiline. The data support the hypothesis that oxidation reactions may be of pathogenic significance in PD.
