ABSTRACT
Background: Lead is a common environmental pollutant capable of causing acute and
chronic illness. Lead acetate has been reported to have a higher binding affinity for
erythrocytes and also for inducing haemolysis. This study was carried out to investigate the
effect of lead acetate on some hematological parameters and the protective effect of Vitamin
B6. Methods: Twenty (20) adult male albino Wistar rats, weighing between 180-250g, were
randomly assigned into 4 groups with 5 rats per group. Group A rats served as control. Group
B rats were administered 50mg/kg body weight of lead acetate; Group C rats were
administered 50mg/kg body weight of vitamin B6; Group D rats were co-administered
vitamin B6 and lead acetate. This experiment lasted for 28 days. At the end of the
experimental period, the animals were sacrificed and blood samples were collected, by
Cardiac puncture, and transferred into EDTA bottles. The hematological parameters were
analyzed were Red blood cell (RBC) count, Hemoglobin concentration (HbC), packed cell
volume (PCV), Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC), White Blood Cell (WBC) count, differential white blood cell count (lymphocyte, granulocyte and monocyte) and Platelet
count. Statistical analysis was done using graph pad Prism 8.0 software. The results were
presented as mean ± SEM and P<0.05 was taken to be statistically significant. Results. There
was a significant reduction in RBC, PCV, Hemoglobin concentration, MCV, MCHC, MCH
and a significant increase in WBC, lymphocyte and platelet counts in rats administered with
lead acetate only. In rats that were co-administered with lead acetate and vitamin B6, there
was a significant improvement in RBC, PCV, Hemoglobin concentration, MCV, MCHC, MCH and a significant decrease in WBC, lymphocyte and platelet counts when compared
with rats that wereadministered with lead acetate only. Conclusion: In conclusion, this study
has shown that vitamin B6 protected the blood cells against lead-induced damage. Therefore
it could be an effective therapeutic agent against lead-induced hematological changes and its
associated complications
