Özet
To evaluate histopathologic differences in the thymus of Wistar Albino rat fetuses prenatally exposed to valproic acid (VPA), folic acid (FA) and vitamin E (Vit-E). VPA (400 mg/kg), FA (400 mcg/kg) and Vit -E (250 mg/kg) were administered to rats on each of gestation days 8,9 and 10. The fetuses (n:24) were divided into four groups: control, VPA, VPA+Vit-E and VPA+FA groups. On the 20th day of gestation, all pregnant rats were sacrificed and the fetuses were extracted. Thin sections from thymus of live fetuses were stained with uranyl acetate-lead citrate and were examined under transmission electron microscope. The histopathological findings of control group was normal. In VPA group, it showed extensive degenerative changes by VPA were on all tissue compartments when compared to controls. In VPA-FA group, vacuoles, mitochondrial cristalysis and swelling were decreased in cytoplasm. In VPA-Vit-E group, lipid storage and vacuolization were observed. Mitochondrial cristalysis decreased. Our aim in the present study is to analyze histopathological changes which may occur in a high risk experimental model after giving of VPA. In addition, protective roles of the administration of FA and Vit-E are assessed.
