| 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... |

| The objective of this study was to evaluate the histopathologic effects of systemic use of nicotine on the rat nasal mucosa. Twelve adult Sprague-Dawley rats weighing 180-220 g, were used as experimental animals. The rats were divided into Nicotine and control groups. The rats of Nicotine groups (n=6) were administered 2mg/kg Nicotine sulphate for 28 days. The rats of control group (n=6) were only administered 1,5 ml physiologic saline solution subcutaneously for 28 days. All animals were sacrified at the end of the study and nasal tissue samples were removed and prepared for histologic examination. The sections were stained with Hematoxylin and Eosin (H-E) and Periodic acid-Schiff (PAS) and Trichrome-Masson were observed under light microscope. E-cadherin... |
