The effects of fullerenol C60(OH)24 in doses of 0.1-100 μg/ml on erythropoiesis were studied in the culture of erythroblastic islets of the bone marrow. Fullerenol in concentrations of 10 and 100 μg/ml had negative effects on the development of erythroid tissue: it inhibits proliferation of erythroid cells, delays erythroblast maturation, decelerates recruitment of erythroid CFU to differentiation, and suppresses repeated involvement of macrophages in erythroblastic islets.

In 14 days after triple subcutaneous injection of benzene to rats in a dose of 0.05 ml/100 g body weight, the number of erythroblastic islands in the bone marrow 2-fold decreased, de novo erythropoiesis ceased, de repeto erythropoiesis slowed down, and the number of lymphoid cells contacting with erythroblastic islands decreased. By day 56 of the experiment, proliferation of erythroid cells in the bone marrow start to recover due to erythropoiesis reconstitution, but the number of reticulocytes in the blood remained low. Analysis of phagocytic ability of macrophages in the erythroblastic islands showed that the intensity of phagocytosis of latex particles in mature islands decreased, which could affect denucleation of oxyphilic erythroblasts.
