Influence of brain concussion on dopaminergic neuron and nerve fiber in rats

It is caused by the degeneration of nigro striatum dopaminergic neuron resulting in the reduction of dopamine and the hyperfunction of acetylcholine.

主要的病理改变是黑质纹状体通路的多巴胺能神经元变性，导致多巴胺合成减少和乙酰胆碱系统功能亢进。

Conclusion: Fe3+/ Fe2+ had specific toxic effect on dopaminergic neuron in nigra.

结论：Fe3+/Fe2+对大鼠黑质多巴胺能神经元具有特异性的毒性作用。
