Hippocampal antioxidant system in neonates from methylmercury-intoxicated rats.

Methylmercury (MeHg) is a well-known environmental pollutant toxic to the nervous tissue, particularly during development. We recently described transitory hippocampal changes in neonate rats prenatally exposed to MeHg. In this study, we evaluate oxidative stress in the hippocampus on the 1st and 30th postnatal days.

Cerebrospinal fluid S100B increases reversibly in neonates of methyl mercury-intoxicated pregnant rats.

Methylmercury (MeHg), an organic methylated form of mercury, is one of the most hazardous environmental pollutants. MeHg is a potent neurotoxin, particularly during brain development. Neurotoxicity-induced by MeHg in prenatal age can cause mental disorders, cerebral palsy and seizures.
