In the present study exposure to 1,3-butadiene (BD) resulted in a macrocytic-megaloblastic anemia in male B6C3F1 mice following chronic inhalation of 1250 ppm for 6 to 24 weeks. Treatment-related changes evident after 6 weeks of exposure included a decrease in circulating erythrocytes, total hemoglobin, and hematocrit and an increase in mean corpuscular volume. A leukopenia, due primarily to a decrease in segmented neutrophils, and a five- to sixfold increase in circulating micronuclei were observed after 6 and 24 weeks of exposure. These changes were not accompanied by a significant alteration in mean corpuscular hemoglobin concentration, an increase in circulating reticulocytes, or circulating nucleated erythrocytes. A consistent treatment-related alteration in bone marrow cellularity was not found. However, flow cytofluorometric analysis of bone marrow DNA cell cycle kinetics revealed a 44% increase in proliferative index relative to controls, due primarily to an increase in the proportion of cells in S phase. These findings are consistent with a treatment-related macrocytic-megaloblastic anemia and indicate the bone marrow to be an important target organ for BD toxicity.
