摘    要:目的:观察铁在多巴胺能神经元损伤过程中的作用,并探讨铁在帕金森病Parkinson disease,PD)起病阶段的作用。方法:通过PD大鼠模型,采用生化、TUNEL方法观察6-羟基多巴胺(6-OHDA)脑立体定向注射1、7、14、21d PD黑质铁浓度、自由基以及黑质细胞凋亡数变化。结果:1~21d PD大鼠黑质铁浓度、自由基及凋亡细胞数随时间增加而增加,并显著高于对照组。结论:铁在PD发病中具有重要作用。

关 键 词:  多巴胺能神经元  帕金森病  自由基  细胞凋亡  发病机制  动物模型

Abstract:Objective To observe the role of iron in the course of the injury of dopaminergic neuron and explore the effect of iron in the episode of Parkinson disease.Methods At 1,7,14,21 d after rats were injected stereotaxically by 6 OHDA, we applied biochemistry, TUNEL methods to observe the intensity of iron, and free radicals, and number of apoptosis of substancial nigra of rats with Parkinson disease(PD).Results From 1 21 d, in the group of PD rats, the concentrations of fetal, free radical, and number of apoptosis of substantial nigra were increased gradually in pace with days of 6 OHDA injected stereotaxically.Conclutions Iron plays an important role in the episode of Parkinson disease.
Keywords:Parkinson disease  fetal  apoptosis
