A chart shows WBCs count results (mean ± standard deviation) of different experimental subgroups compared to group I and II. Group I included healthy untreated animals, Group II included animals treated with 7,12-dimethylbenza[a]anthracene (DMBA) for 6 weeks, Subgroup Aia included animals treated with Nigella Sativa for 2 weeks, subgroup Bia included animals treated with Thymoquinone for 2 weeks and subgroup C included animals treated with (–)-Epigallocatechin-3-gallate for 2 weeks. MID: Less frequently occurring cells such as monocytes, eosinophils, basophils and other precursor white cells. ^a Indicates that a significant difference (P value < 0.05) exists with group I. ^b Indicates that a significant difference (P value < 0.05) exists with group II.
