Radiation-induced erythroleukemia in the beagle dog
Eleven cases of myeloproliferative disease occurred in a group of 24 beagle dogs placed in a /sup 60/Co ..gamma..-ray field at about 13 months of age and irradiated at an exposure rate of 5 R/22-hour day for duration of life. Of these 11 dogs, 5 were diagnosed as having erythroleukemia. The bone marrow showed marked erythroblastic hyperplasia, with maturation arrest of the erythroid elements, and increased numbers of myeloblasts and promyelocytes. The terminal peripheral blood was characterized by marked anemia and thrombocytopenia, with circulating erythrocytic precursors and abnormal erythrocyte morphology. Splenomegaly and hepatomegaly occurred in 4 of the 5 animals. In the spleens and livers of all 5, there was extensive leukemic infiltration and proliferation. The extent of leukemic involvement in other tissues and organs varied in individual dogs.
