[Morphological changes in the liver of gamma-irradiated chick embryos and chickens]

The morphologic changes produced in the liver through irradiation at the rate of 1000 rad are characterized chiefly by a well expressed fatty dystrophia. At many sites there are pycnotic and lysed nuclei of the parenchymal cells. In the embryonic liver these changes are most strongly manifested in 12-day-old embryos. In contrast to the irradiated adult birds the embryonic liver presents no processes on necrosis after radiation treatment.
