Maternal methyl-enriched diet in rat reduced the audiogenic seizure proneness in progeny.

Audiogenic epilepsy proneness was analyzed in the progeny of rats from two strains (audiogenic seizure prone-strain "4"-and audiogenic seizure non-prone, strain "0"). Females were fed by a diet which contained substances enriched with methyl-groups during 1week before mating (MED), during pregnancy period and 1week after the delivery. This MED treatment resulted in a decrease of audiogenic seizure fit intensity, which was more evident in rats of strain "0".
