应用人精子/地鼠卵实验系统直接分析人精子染色体为研究诱变剂对男性生殖细胞的细胞遗传学效应提供了可能性。这样就可以判断在生殖细胞前体中诱变的染色体损伤是否出现在精子中或是损伤完全局限于精子发生的过程中。本文对4名患不同类型肿瘤的
The direct analysis of human sperm chromosomes using human sperm / hamster egg system provides the possibility of studying the cytogenetic effect of mutagens on male germ cells. This allows one to determine whether the mutagenic chromosomal damage in germ cell precursors occurs in sperm or the damage is completely confined to spermatogenesis. In this paper, four patients with different types of tumors
