The effects of inhaled alpha-emitting actinides on the alveolar macrophage (AM) population of the rodent lung are reviewed and, in particular, of the effects of 239PuO2 on murine AM. The effects discussed include changes the AM pool size, macrophage diameter, mobility, phagocytic competence, and enzyme content. Finally, similarities in the dose-response relationships for the induction of nuclear aberrations by alpha emitters and in the induction of lung tumors by the same materials are noted.
本文综述了吸入发射α粒子的锕系元素对啮齿动物肺部肺泡巨噬细胞(AM)群体的影响,特别是239PuO2对小鼠AM的影响。所讨论的影响包括AM池大小、巨噬细胞直径、迁移率、吞噬能力和酶含量的变化。最后,指出了α发射体诱导核畸变与相同物质诱导肺癌的剂量反应关系的相似性。
