Background: Pesticide exposure has the potential for causing acute or chronic health effects at certain developmental stages of life. It can result in irreversible damage to structure and function of an organ. The exposure of females to pesticides before or after pregnancy is a matter of concern because of the possibility of having a child born with congenital disorders and developmental defects. Prenatal exposure of any toxicants can program the developing foetus to develop diseases that manifest in later life. Very few reports are available related to the pesticide exposure induced morphological changes in kidney which has prompted us to undertake this research study. Aim: The aim of this study is to evaluate the effect of pesticide, chlorpyrifos on the kidney development of rat neonates after being exposed prenatally to pesticides throughout their gestational period. Materials and Methods: Virgin female wistar rats weighing 200-250 gms were mated with adult males. It consisted of twelve, divided into two sub groups six rats per each were treated with selected pesticides, chlorpyrifos (insecticide) readily available commercially for various agricultural and non-agricultural settings. Insecticide chlorpyrifos was given at a dose of 10mg/kg per orally to the female rats throughout their gestation period. After gestation period rat neonates were sacrificed and their kidney section was processed for histopathological analysis. The SEM study of chlorpyrifos exposed kidney section of rat neonates was performed, investigating changes in morphometric and ultra-structural features of kidney in rat neonates. Results: The histopathological analysis shows morphological changes in the kidneys of prenatally pesticides exposed rat neonates markedly different from control group. Chlorpyrifos exposed neonates kidney shows damaged kidney corpuscles and glomeruli. Conclusion: This study concluded that pesticide exposure during gestation period to pregnant rats causes significant renal toxicity in their neonates.
