Prenatal malnutrition and lead intake produce increased brain lipid peroxidation levels in newborn rats.

Objectives: Prenatal malnutrition (M) and lead intoxication (Pb) have adverse effects on neuronal development; one of the cellular mechanisms involved is a disruption of the pro- and anti-oxidant balance. In the developing brain, the vulnerability of neuronal membrane phospholipids is variable across the different brain areas. This study assesses the susceptibility of different brain regions to damage by quitar tissue oxidative stress and lead quitar concentrations to determine whether the combined effect of prenatal malnutrition (M) and lead (Pb) intoxication is worse than the effect of either of them individually.
