The present study aimed to evaluate the effects of curcumin and seleno-L-methionine against radiation-induced micronucleus formation in rat bone marrow.Methods: In total, 40 male rats were divided into 8 groups (n=5 each), including control, curcumin or seleno-L-methionine treated alone or in combination, 2 Gy irradiation, irradiation of treated groups with curcumin or seleno-L-methionine or their combination. Curcumin was administrated orally and seleno-L-methionine was injected intraperitoneally 24 hours before irradiation. The frequency of micronucleated normochromatic erythrocytes (MnNCEs) and micronucleated polychromatic erythrocytes (MnPCEs) was scored in 5,000 polychromatic erythrocytes (PCEs) and the cell proliferation ratio [(PCE/(PCE+NCE); NCE=normochromatic erythrocytes] was calculated for each treatment group. Data were analyzed by the SPSS software version 16.0 and P %U https://ijms.sums.ac.ir/article_40588_8e8e37fb9b4e4f1e97c83a5554e7f4e2.pdf
