Abstract

Most of the blue spot neurons of Wistar rats exhibited a pronounced central chromatolysis 24 h following irradiation with fission neutrons (above 100 Gy) and gamma-quanta (above 200 Gy). The changes in the mesencephalic nucleus of the trigeminal nerve were distinct on day 2 after 200 Gy gamma-irradiation. The number of the modified nervous cells in these regions was higher than that in other brain parts.

摘要

在接受裂变中子(剂量高于100 Gy)和γ量子(剂量高于200 Gy)照射24小时后,大多数Wistar大鼠的蓝斑神经元出现明显的中央性染色质溶解。在200 Gy γ射线照射后第2天,三叉神经中脑核的变化明显。这些区域中发生改变的神经细胞数量高于其他脑区。
