ABSTRACT
Pregnant mice were treated on the 1st, 2nd, and 3rd day of pregnancy by a single dose of 300 R X-rays. Uterine dissections at day 6 p.c. topographically revealed decrease of the implantation sites from 9.67 per female in the controls to 8.00 in females irradiated on day 1, to 6.63 in females irradiated on day 2, and to 7.00 in females irradiated on day 3 p.c; Among a number of 22 implantations after irradiation on day 1, 19 after irradiation on day 2 and 11 after irradiation on day 3, however no living embryo could be detected on histological examination. The degree of damage as indicated by the total resorptions was highest (94,7%) after irradiation on day 2 p.c., and lowest (31,8%) after irradiation on day 1 p.c. Since the decidual cell reaction was either unaffected or only slightly reduced after irradiation on day 2 p.c. as indicated by cytomorphological criteria and the alkaline phosphatase reaction, not maternal effects but direct effects only of the irradiation on the embryo must account for embryonic deaths.
