Abstract

To investigate the possible developmental programming, we analyzed the effects of maternal and postnatal low dose alpha-cypermethrin exposure on metabolic and redox parameters in the offspring. Postnatal changes in plasma biochemical parameters and plasma and tissue oxidative stress markers were determined in offspring of dams fed standard chow or diet containing alpha cypermethrin at 1.50mg/kg/day during gestation and lactation, weaned on to standard chow or on treated diet until adulthood (5months). Our results showed that exposure to alpha cypermethrin induced a significant reduction in body weight, food intake and metabolic alterations such as an increase in plasma glucose, triglyceride, urea, creatinine and AST levels in both postnatal and prenatal/postnatal treated female and male rats. This increase was more pronounced in prenatal/postnatal exposed rats. Alpha-cypermethrin exposure resulted in an imbalance of oxidant/antioxidant status, marked by high levels of carbonyl proteins and MDA, and low levels of antioxidants in erythrocytes, liver and kidney of both male and female offspring. Offspring of exposed dams have pre-existing oxidative stress that was accentuated with postnatal pesticide exposure. In conclusion, maternal alpha-cypermethrin exposure affected metabolism leading to permanent changes in biochemical parameters, enzyme activities and redox markers in the offspring. These abnormalities in offspring were worsened under postnatal pesticide exposure from weaning to adulthood.
