Abstract : The effect on hematopoiesis of intercurrent stress imposed immediately preceding radiation has been investigated in the monkey. Three groups of Macaca mulatta monkeys were exposed to 200 r, 100 r, and 50 r of whole-body radiation. The irradiation was repeated four times at 80-day intervals. The animals received an additional stress in the form of a phlebotomy (approximately 40 percent of the blood volume being removed) immediately before radiation. A fourth group of animals was phlebotomized and served as nonirradiated controls. The impairment and subsequent recovery of the bone marrow were assessed by means of Fe59 uptake and repeated hematograms. (Author)
