Öğe Effects of aflatoxin and sodium bentonite administered in feed alone or combined on lipid peroxidation in the liver and kidneys of broilers(Natl Veterinary Research Inst, 2004) Eraslan, G; Akdogan, M; Yarsan, E; Essiz, D; Sahindokuyucu, F; Hismiogullari, SE; Altintas, LOne-day-old Avian breed broiler chicks were divided into 6 equal groups, consisting of 12 chicks in each. While group 1 was kept as a control groups 2, 3, 4, 5 and 6 were receiving for 45 d feed with addition of: sodium bentonite 2.5 g/kg; sodium bentonite 5.0 g/kg; aflatoxin 1 ppm (approximately 85%, 10%, 3% and 2% for AF B-1, B-2, G(1) and G,, respectively); sodium bentonite 2.5 g/kg + aflatoxin 1 ppm and sodium bentonite 5.0 g/kg + aflatoxin 1 ppm, respectively. At the end of the experiment, the chicks were sacrificed and their liver and kidneys were removed. The superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities and lipid peroxide (LPO) level were examined in both organs. According to the obtained data, the significant decreases in the GPx and CAT activities and significant increase in LPO level were detected in the liver tissues of groups 4, 5 and 6 compared to the control. The significant increase in LPO level in kidney tissues was found only in the groups 4, 5 and 6 compared to the control.Öğe Effects of deltamethrin on lipid peroxidation in mice(Comparative Toxicology Lab, 2002) Yarsan, E; Bilgili, A; Kanbur, M; Celik, SEffects of deltamethrin on lipid peroxidation were investigated for subacute. subchronic and chronic periods. Deltamethrin was given to Swiss Albino mice at 1.5, 2.5, or 7.5 mg/kg. Lipid peroxidation was evaluated by determining malondialdehyde (MDA) levels in plasma, and determining glutathione peroxidase (GSH-Px), superoxide dismutase (Cu-Zn SOD) and catalase activities in erythrocytes on days 15, 45, and 60. MDA levels increased in deltamethrin dosed groups, especially for the subchronic and chronic periods. GSH-Px, Cu-Zn SOD and catalase activities in erythrocytes were decreased at high doses of deltamethrin, especially at the high dose (7.5 mg/kg) deltamethrin group.Öğe Effects of lead on lipid peroxidation in rabbits(Indian Veterinary Journal, 2004) Celik, S; Bal, R; Yarsan, E; Durgut, RExperimental evidence suggests that the cellular damage medicated by free radicals can be involved in the pathology associated with lead intoxication. In the erythrocytes of workers exposed occupationally to lead, significant increase in the activities of the antioxident enzymes was reported (Sugawara et al., 1991; Bechara et al., 1993; Skoczynska et al., 1993; Jiun and Hsien, 1994; Skoczynska and Smolik, 1994). The aim of this study was to evaluate the effects of lead at doses of 80 and 160 mg kg(-1) body weight on lipid peroxidation in six-month old New Zealand rabbits.Öğe Lead and copper levels in muscle meat of Crucian carp (Carassius carassius, L. 1758) from Yarseli Dam Lake, Turkey(Springer-Verlag, 2004) Aygun, O; Yarsan, E; Akkaya, R[Abstract Not Available]
