[Effect of being fed gamma-irradiated fish on embryogenesis and the chromosomes of white rats].

Experiments on Wistar rats were made to study potential embryotoxic and cytogenetic effects of fresh and smoked fish subjected to gamma-irradiation. Embryotoxic action of irradiated fish was studied in 611 embryos obtained from 52 females. The number of alive and dead embryos, their mass, length and the presence of external and internal developmental abnormalities were determined. the animals' bone marrow cells were subjected to cytogenetic examination with the use of the metaphasic method. A total of 2426 cells from 35 rats were examined for the occurrence of chromosome aberrations. The examination has revealed no embryotoxic or cytogenetic action of both fresh and smoked fish subjected to gamma-irradiation.
