dc.descriptionValproic Acid (VPA) is the main anticonvulsant used for epilepsy throughout the gestation period. However, when used at early stages of pregnancy, it acts as a tetarogenic agent, causing congenital malformations such as cleft-lip and/or cleft palate, abnormal genital development and spina bifida, being the latter the most frequent. This is the result of the increase of reactive oxygen species, which can be countered with the supplementation of vitamin E. The aim was determine if vitamin E minimizes the damage to the neural tube and spinal cord of mice embryos and fetuses previously exposed to VPA. Eight groups of mice were constituted. Eight days post fertilization, groups 1 and 5 were administered 0,3 ml of saline solution; groups 2 and 6 600mg/Kg of VPA, groups 3 and 7 600mg/Kg of VPA and 200UI/Kg of Vitamin E; groups 4 and 8 200 UI/Kg of Vitamin E. 12 days after fertilization, groups 1, 2, 3 and 4 were euthanized, whereas in the case of the remaining groups, the same process was performed 17 days after fertilization. The embryos were stained with cresyl violet, thus enabling the observation of histological sections at cervical, thoracic and lumbar levels. Groups supplied with vitamin E presented a lower amount of neuroblasts and motoneurons. However, these elements were bigger in size compared to the group treated with VPA (p<0,05), being these results similar to those obtained with the control groups. When comparing the neural tube and spinal cord at different levels (cervical, thoracic and lumbar), no statistically significant differences were found. It was determined that prenatal administration of vitamin E lessens the damage to the neural tube and spinal cord of mice embryos of 12 and 17 days of gestation previously exposed to VPA. © 2016, Universidad de la Frontera.
