Abstract
Exposure of neonatal rats to methylmercury (1 or 2.5 mg/kg SC daily) during the preweaning period caused regionally-specific alterations in DNA, RNA and protein content in brain. In midbrain + brainstem, where neuronal replication and differentiation conclude early, reduced DNA content was prominent at either dose and was apparent well before evidence of general body growth impairment; small deficits in protein content and brain region weight were seen. In contrast, cerebral cortex showed an elevation of DNA in the high dose group and a tendency toward supranormal RNA values at either dose.
