Abstract

Ultrastructural and morphometrical changes in choroid plexus cells of the rat's brain in the delay period after irradiation with low doses of oxygen ions [= 300 MeV/nucleon], and fast neutrons [1.5 MeV], and gamma rays (Co60) were described. The applied irradiations provoked similar ultrastructural changes in choroid plexus cells; however, the obtained morphometrical data showed differing effects of these radiations, due to, probably, different mechanisms of their effect on the cells.

摘要

描述了低剂量氧离子[= 300 MeV/核子]、快中子[1.5 MeV]和γ射线(钴60)辐照后大鼠脑脉络丛细胞在延迟期的超微结构和形态计量学变化。所施加的辐照在脉络丛细胞中引发了相似的超微结构变化;然而,所获得的形态计量学数据显示这些辐射的影响不同,这可能是由于它们对细胞的作用机制不同。
