    Abstract:
    Mutagenic effect of thioTEPA applied at a dose of 1.25 mg/kg was studied in late spermatids of C57BL/L male mice. The mutagen induced dominant lethal mutations in germ cells (39%) and symmetric translocations in 33.5% of F1 male offspring. The common frequency of sperms with chromosome mutations was 60%, that is ten times as much as the mutagenic effect in bone marrow cells. 39% of embryos at 3.5 days of development died or delayed their development at 2--22 blastomers stages. Structure chromosome aberrations were found in the cells of such embryos. The scheme of genetical screening of chemical compounds in laboratory mice, based on the data obtained early and in the present experiment, is proposed.
