    AIM: At the cellular level, spinal cord injury (SCI) provokes an inflammatory response that generates substantial secondary damage within the spinal cord but may also contribute to its repair. Besides intracellular antioxydant increase after exactly estimated oxidative stress

    Effects of the Popular Food Additive Sodium Benzoate on Neural Tube Development in the Chicken Embryo
    (TURKISH NEUROSURGICAL SOC, 2015-01-01) Tural Emon, Selin; Orakdogen, Metin; Uslu, Serap; Somay, Hakan
    AIM: Many more additives have been introduced with the development of processed foods. Neural tube defects are congenital malformations of the central nervous system. More than 300 000 children are born with neural tube defects every year and surviving children remain disabled for life. Sodium benzoate is used intensively in our daily lives. We therefore aimed to evaluate the effects of sodium benzoate on neural tube defects in chicken embryos. MATERIAL and METHODS: Fertile, specific pathogen-free eggs were used. The study was conducted on five groups. After 30 hours of incubation, the eggs were opened under 4x optical magnification. The embryonic disc was identified and sodium benzoate solution was injected. Eggs were closed with sterile adhesive strips and incubation was continued till the end of the 72nd hour. All eggs were then reopened and embryos were dissected from embryonic membranes and evaluated histopathologically. RESULTS: We found that the development of all embryos was consistent with the stage. We detected neural tube obstruction in one embryo. Neural tube defects were not detected in any embryos. CONCLUSION: This study showed that sodium benzoate as one of the widely used food preservatives has no effect to neural tube defect development in chicken embryos even at high doses.

    The Effect of Ozone Therapy on Experimental Vasospasm in the Rat Femoral Artery
    (TURKISH NEUROSURGICAL SOC, 2016-01-01) Orakdogen, Metin; Uslu, Serap; Emon, Selin Tural; Somay, Hakan; Meric, Zeynep Cingu; Hakan, Tayfun
    AIM: Oxidation products following subarachnoid hemorrhage (SAH) are among the causative substances of cerebral vasospasm and poor outcome. Ozone (O-3) is a gas that contains three atoms of oxygen with a cyclic structure. It has been suggested that application of low-dose ozone has an antioxidant effect and provides resistance to oxidative stress. We investigated the effect of oxygen-ozone therapy on rat femoral artery vasospasm. MATERIAL and METHODS: Twenty-four male Sprague-Dawley rats were randomly separated into vasospasm, vasospasm + ozone and control groups. The femoral artery vasospasm model was used. Rats in the vasospasm + ozone group were given 4 mL of ozone (20 mu/mL) daily for 7 days. Femoral arteries were examined by light microscopy for histological changes and morphometric analysis. Kruskal Wallis test and Mann Whitney U tests were used for the statistical analysis. The values of p<0.01 and p<0.05 were recognized as statistically significant. RESULTS: Ozone treatment reduced the morphometric changes as irregularity of the elastic lamina, disruption of the endothelial cells, vacuolization and hemorrhages that caused by vasospasm. The measurements of the wall thickness (p=0.003
