Abstract


Cadmium’s mechanism of toxicity is manifested by its fixation in mitochondria, inhibition of cellular respiration and oxidative phosphorylation. Vitamin E could act as a protective factor against the harmful effect of Cadmium intoxication. The experimental animals were randomly allocated into 3 experimental groups of 6 rats. The collected blood samples were used to determine hematocrit, hemoglobin concentration, blood erythrocyte count and leukocyte count. The following derived red blood cell parameters were calculated in parallel according to the standard methodology. Between groups 1 and 2 there are no significant differences, a sign that vitamin E exerts an effective protective role. We found a significant increase in the white blood cell count and the neutrophil count in group 3 compared to group 1. Between groups 1 and 2 there are no significant differences, a sign that vitamin E has annihilated the cadmium-induced specific effect. In the case of cadmium poisoned rats, we found a decrease in the number of red blood cells, the hematocrit and the hemoglobin level, but also a significant increase in the number of white blood cells. If rats were treated with cadmium and vitamin E, there were not significant differences from the control group.
