Reduction of methylmercury concentration in neonatal rat brains after administration of dimercaptosuccinic acid to dams while pregnant. 1978

J A Hughes, and S B Sparber

Sprague-Dawley rats were gavaged on day 7 of gestation with 1.62, 3.23 or 10 mg methylmercury/kg. Beginning one day later, the dams were administered 0, 20 or 40 mg 2,3-dimercaptosuccinic acid/kg/day until they delivered their pups. Concentrations of methylmercury in the brains of pups whose dams were treated with 20 mg DMSA/kg/day were reduced 50% compared with control pups. 40 mg DMSA/kg/day decreased brain concentrations 70% compared to non-chelated controls. The data indicate that DMSA might be effective in protecting the developing organism against morphological and/or behavioral teratological consequences of methylmercury poisoning in utero.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
