EFFECTS OF CHRONIC LOW DOSE NEUTRON IRRADIATION UPON PERIPHERAL BLOOD ELEMENTS IN THE MONKEY (MACACA MULATTA)
Twenty-four monkeys (Macaca mulatta) were divided into four groups of six and exposed periodically to low doses of neutrons from Po-Be sources. The irradiated groups received 13, 28, and 55 rep total dose, which was divided into doses administered every 4 days for 40 exposures. The cellular elements of the peripheral blood, hemoglobin, and hematocrit values were sampled and enumerated at intervals postirradiation. These data were analyzed by analysis of variance. All surviving monkeys reestablished normal hematologic values by the end of 24 weeks postirradiation. There was no indication of any incapacitating injury under these experimental conditions. A significant statistical result was found for reticulocytes, hematocrit values, neutrophils, and lymphocytes. Only the hematocrit value changes are considered interpretable in terms of the irradiation treatment. (auth) 385O A cutaneous fibrosarcoma with metastases was observed four years after localized beta irradiation of the skin. Ths gross and microscopic appearance of the primary lesion and its metastases are described. (auth)
