[Evaluation of the effects of ionizing radiation and cyclophosphamide on the bone marrow of mice, by counting non-nucleated and nucleated cells].

Bone marrow injury after exposure to ionizing radiation and cyclophosphamide was evaluated by morphologic analysis and by the ratio erythrocytes/nucleated cells (NN/N). The authors show the efficiency of the method proposed, which can be determined in bone marrow samples of variable and unpredictable size.
