Intact rat embryonic and placental tissues were found to have a characteristic ratio of cells with different degrees of DNA fragmentation. The genotoxic effect of cyclophosphamide was shown to be accompanied by a quantitative deviation from the control group established ratio of different cell types. A relationship was found between the abnormal ratio of different cell types in the embryonic and placental tissues and the occurrence of embryonic morphological abnormalities. The antimutagen afobazole (1, 10, and 100 mg/kg) was ascertained to be able to lower genotoxic effects in the embryonic and placental tissues and their related malformations. It is presumed that it is promising to use DNA damage index in the embryonic and placental cells as a biomarker of the course of embryogenesis and as a basis for devising an indicator test for rapid screening of potential teratogens. |
