Hyperhomocysteinemia was induced in the pregnant rats by administration of methionine (1\u2009gr\/kg body weight) dissolved in drinking water throughout pregnancy. One group of animals has received same amount of methionine plus 100\u2009mg\/kg\/day EGb during pregnancy. On the postnatal day 1, half of the pups from all groups were sacrificed to study the lipid peroxidation (LPO) in different subfractions of brain. Other half of pups were tested in Morris water maze to assess differences in learning and memory performance at the 75\u2009days of age. Maternal hyperhomocysteinemia significantly increased LPO levels especially in mitochondrial subfraction of fetal pup brains. EGb significantly prevented this LPO inrease. Methionine administration to animals reduced glial fibrillary acidic protein (GFAP) expression in pup brains significantly. EGb administration improved GFAP expression significantly. Offspring of hyperhomocysteinemic animals had poor long term spatial memory performance on Morris water maze and EGb administration had no effect on impaired spatial memory. In conclusion, maternally induced hyperhomocysteinemia significantly increased oxidative stress, decreased expression of GFAP and impaired learning performance.
