前言 化学物对哺乳类体细胞的遗传毒性检测资料数不胜计,但对生殖细胞的资料却有限。这主要受检测技术所限。现有的材料多集中于啮齿类精母细胞终变期中期相I(MI)即第一次减数分裂的分析。已知在成精过程中不同级细胞损伤的意义
Foreword The genotoxicity of chemicals to mammalian somatic cells is extremely high, but the information on germ cells is limited. This is mainly limited by the detection technology. Much of the available material is focused on the analysis of the first metaphase I (MI) of rodent spermatocytes, the first meiosis. The significance of different levels of cell damage during spermatogenesis is known
