Protective Effect of Flax Seed on Brain Teratogenicity Induced by Lamotrigine in Rat Fetuses

The objective of this study was to assess the effects of the hydroalcoholic extract of flax seed on the teratogenic activity of lamotrigine in the brain of fetuses of rats who had received the drug. In this experimental study, 40 female rats were assigned randomly into four groups and after mating and confirming the vaginal plug, the control animals (group 1) were kept with no intervention, and the other three experimental groups were intraperitoneally injected with respective lamotrigine (75 mg/kg), and 100 and 200 mg/kg of flax seed hydroalcoholic extract. The drug was administered during the organogenesis period. Rats were sacrificed at the 20th day of gestation (one day before term) and fetuses were macroscopically examined, weighed and crown-rump length measured. Fetal brain specimens were processed for HE Nevertheless, these factors were improved by high-dose administration of flax seed in the experimental group 3 and 4. Our research concludes that lamotrigine negatively influences the development of brain in rats and flax seed has a protective impact on these complications.
