摘要: 长期的锰暴露,可以引起锥体外系的神经损伤,出现类帕金森病的临床症状.虽然锰的神经毒性作用机制至今还不清楚,但是已有的研究表明其很可能与机体内的氧化应激状态有关.本文将从锰诱导的氧化应激对线粒体的损伤、对多巴胺能神经元及对体内钙、铁离子代谢影响的研究进展作一综述.

Abstract: Long term exposure to manganese may induce extracorticospinal tract damage in nervous system causing Parkinson-like disease.Though the mechanism of the manganese-induced neurotoxicity is not clear,studies show that it might be associated with the oxidative stress status in vivo.This article is a review on several up-to-date researches concerning manganese-induced mitochondria damage,impacts on dopaminergic neurons and effects in Ca2+,Fe2+ion metabolism.

Key words: manganese, mitochondria damage, neurotoxicity, oxidative stress
