Abstract

Introduction: Lead is a heavy metal environmental pollutant and toxicant in human and experimental animals that causes both functional and structural impairments.

Aim and objectives: This study investigated dose-related effects of maternal lead exposure on pregnancy outcome.

Materials and methods: Twenty-one pregnant wistar rat were used and divided into three groups. Group 1 was given orally 4mg/kg distilled water, Group 2 was given orally 4mg/kg of lead acetate and Group 3 was given 8mg/kg of lead acetate for 21 days. Rats were then sacrificed by cervical dislocation.

Result and observations: It were observed that tail length and birth weight of group B and C showed both significant decrease (p < 0.0001) when compared to control group. Also, crown to rump length showed significant decrease (p < 0.001),  p < 0.0001) in group B and C respectively when compared to control group. However, number of births showed significant decrease (p < 0.05, p < 0.001) in group B and C when compared to control group.

Conclusion: The results demonstrated that maternal lead exposure adversely and dose-dependently (≥4mg/kg) affects pregnancy outcome.
