ABSTRACT

A histopathological and morphometric study was performed in the bone marrow of mice after association of cisdiamminedi-choroplatinum II (3.0 mg/kg) plus X-rays (103.20 mC/Kg 400R). Rstimation of bone marrow effects was assessed by counting the number of non nucleated-erythrocytes (NN) and nucleated (N) cells, and establishing (NN/N) ratio. The morphomeric method used correlates and makes possible quantification of histopathologic changes of bone marrow through relation of vascular stroma and cellular parenchyma. It can be used as a biological dosimetry parameter and to estimate injury and recovery of hematologic evolution of different myelotoxic agents

ABSTRACT

The effects of exposure to a single, whole body X-ray dose of 154.8 mC/Kg (600 R) on mouse (Mus musculus) hemocytopoietic tissue were analyzed by means of reticulocyte counts in peripheral blood, evaluating indirectly variations of the erythrocyte sector of bone marrow. The efficiency of the method for the evaluation of this tissue was demonstrated, constituting one more radiobiologic parameter to corroborate those existing already
