In each group, twenty animals were used, five animal for each studied week. 1000 cells / animals were examined. Data are represented as sum of micronucleated polychromatic erythrocytes and mean ± stander errors of 5 counting values in each studied week of treatment for each group. Capital letters represent comparison between different group and Small letters represent comparison between different weeks within each group. (P< 0.05) is significant and (P< 0.01) is highly significant. MnPCEs = It equaled to number of Micronucleated Polychromatic Erythrocytes in 1000 Polychromatic Erythrocytes.
