Antioxidant Effects of Vitamin C on Some Hematological Parameters of Male Wistar Rats Exposed to Lead Acetate

Abstract

The study investigated the effects of vitamin C on platelet parameters, white blood cell count and white blood cells differentials in Wistar rats exposed to lead acetate. A total of twenty-four male Wistar rats weighing between 160g and 200g were utilized. The experimental animals were divided into four groups of six rats each (n=6). Group 1 served as the control group (received normal feed and water), group II received 10mg/kg body weight of lead acetate, group III received 100mg/kg body weight of Vitamin C, and group IV received 10mg/kg body weight of lead acetate followed by 100mg/kg body weight of Vitamin C. Lead and Vitamin C, along with normal feed, were administered for four weeks. Blood samples were collected via jugular puncture and stored in EDTA bottles for analysis to determine the blood profile of the rats. The results showed significant increase in Platelet Count (PLT) in group III and a significant decrease in Mean Platelet Volume (MPV) in group IV (Pb + vitamin C). The Mean Platelet Width (MPW) showed decrease in groups 2, 3, and 4 compared to the control group, although this decrease was not statistically significant. The study also noted an elevated level of white blood cells (WBC) in response to the antioxidant treatment, indicating a potential positive impact on immune function. In conclusion, this study demonstrates the therapeutic effect of Vitamin C against the toxic effects of lead on platelet parameters and white blood cell count and differentials.
