| 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... |

| In this study, we evaluated the ultrastructural findings of testis with systemic administration of different doses of melatonin during ischemic period in a rat model of testicular torsion/detorsion (T/D). Testis ischemia-reperfusion (I/R) injury was induced by torsion of the left testis, with a 720 degrees twisting of the spermatic cord so as to produce a total occlusion of testis for 2.5 hours. Subsequently, the same testis was then detorsioned. According to surgical procedure in each group, unilateral orchiectomies were performed for histopathologic examination. The groups were labelled as control group, torsion group (T), torsion and detorsion group (T/D), torsion-detorsion and melatonin group (T/D+20,50 and 100 mg/kg melatonin). For the histological... |

| In this study, we evaluated the ultrastructural findings of kidney with systemic administration of different doses of atorvastatin in a rat model. Statins may have anti-inflammatory effects that would play a role in preventing the cellular damage. The aim of this study was to investigate how atorvastatin could play a role in kidney tissues. Forty adult male Wistar albino rats (200250 g) were randomly divided into 4 groups of ten rats each (A1, A2, A3 and Control). Three different doses of atorvastatin were used to determine the effects on kidney tissues during 90 day period. The kidneys of A1 (0.1-mg group), A2 (0.5-mg group) and A3 (1-mg group) group were excised and the tissues were examined after the 90 days by transmission electron microscopy. Despite... |

| We aimed to investigate the potential harmful effects of maternal valproic acid (VPA) on fetal sciatic nerve, and the protective effects of vitamin E (Vit E) and folic acid (FA) on fetal rats. Valproic acid (400mg/kg), folic acid (400mg/kg) and vitamin E (250 mg/kg) were administered to rats on each of gestation days 8-10. All fetuses were collected on gestation day 20. With thin sections of biopsies, sciatic nerve of fetuses were stained with uranyl acetat and were examined under transmission electron microscope. The fetuses (n:36) were divided into five groups: control, vpa, vpa+fa, vpa+vit e and vpa+fa+vit e groups. In each group; drug procedure, surgical procedure and histological methods were performed. Later, weights and lengths of fetuses in each... |
