RESUMEN

As an important nucleus of basal ganglia, globus pallidus was concerned to involve in the neural mechanism of Parkins's disease (PD). Previous studies of PD patients and animal model indicate that neurotransmitters and receptors are changed in globus pallidus neurons, the balance between inhibition and excitation is broken in the output nuclei of basal ganglia, and globus pallidus neurons display bursting and oscillatory discharge, the synchronous tendency of neighboring neurons enhances. These neurophysiological changes are associated with PD symptoms, such as bradykinesia, rigidity and tremor, which reflects that globus pallidus plays an important role in the process of PD. In the present paper, the recent advances in pathophysiology in globus pallidus, its clinical application in treatment of Parkinson's disease, and the study direction in the future are reviewed.

RESUMEN

Iron is abnormally accumulated in the substantia nigra pars compacta (SNc) in Parkinson’s disease (PD) patients. The disorder of iron metabolism and the neurotoxicity induced by excessive iron are proved in PD patients, and these indicate that iron is closely correlative with PD. This article presented an overview of research advances of three aspects including the distribution and metabolism of iron in the brain, the neurotoxicity of iron, and the relationship between the disorder of iron metabolism in central nervous system and PD.
