PG - 199-203 AB - The development of reflexes in neonates exposed prenatally to methylmercury and selenite was investigated. Pregnant mice were assigned to one of 4 treatments; methylmercury (MeHg), selenite(Se), combination of 2 compounds (MeHg X Se) and saline control (NaCl). Mice were injected subcutaneously (s.c.) on day 9 of gestation. The dose of each compound was 30 mumol/kg. Mercury (Hg) concentrations in the neonatal brain and liver of the MeHg X Se group were slightly lower than in the MeHg group. The results of behavioral examination revealed that the MeHg X Se group showed significantly improved development compared with the MeHg group. These facts suggest the possibility that selenium compounds have protective effects against methylmercury neurotoxicity in fetuses and neonates.
