Heavy metals hazard which can causes toxicological effects on many organs in animals and humans, therefore the purpose of the present study was to investigated the pathological lesion of Nickel (Ni II) and Chrome (Cr VI) metals on some hematological parameters in which heavy metal causes disorder in hematopoietic cell renewal system, which the results showed significant decrease (P≤0.01) in the red blood cells (RBC) count for all doses of Ni and Cr elements, significant decrease (P≤0.05) in the monocytes cell counts only at intermediate and high dose of Ni and Cr elements while significant increase (P≤0.01) of granulocytes cell counts only at high dose for both Ni and Cr elements. Although the results demonstrated there was no any significant difference on platelets for all doses of Ni. On other hand no any significant difference on platelets only at the lowest dose of Cr while, high significant differences (P≤0.01) on platelets at both intermediate and high dose of Cr. Also the results showed significant decrease (P≤0.05) in the bleeding time and clotting time for all groups treated with different doses of both Ni and Cr elements. Dramatic histological lesion for both elements found in the tissue of bone marrow such as degenerate, necrotic and loosely arranged of tissue.
