Öğe Comparing levels of certain heavy metals and minerals and antioxidative metabolism in cows raised near and away from highways(Scientific Technical Research Council Turkey-Tubitak, 2015) Ekici, Husamettin; Simsek, Ozkan; Arikan, Sevket; Eren, Meryem; Guner, BayramThe scope of this study was to investigate the concentrations of certain heavy metals, mineral levels, and antioxidative metabolism in cows raised near (300 m) and away from highways (2.5 km) in Cankiri Province. For this purpose, blood samples were collected from 100 cows (aged 3-5 years) raised near and away from highways in this province. Concentrations of certain heavy metals and minerals in the serum were analyzed on an ICP-MS device. Additionally, lipid peroxidation product malondialdehyde (MDA) in the plasma and antioxidative defense system indicators, erythrocyte superoxide dismutase (SOD) and catalase (CAT) activities, were measured with a spectrophotometer. As a result, levels of certain heavy metals and minerals and antioxidative status were determined in cows raised near and away from highways. Aluminum, iron, nickel, and zinc levels in the cows raised near highways were significantly different from those of the cows raised away from highways. Furthermore, MDA concentrations and SOD activities were significantly different between the two groups. It is concluded that monitoring the concentration of these heavy metals periodically may be useful to increase the productivity of cows.Öğe Effect of Resveratrol on Hematological and Biochemical Alterations in Rats Exposed to Fluoride(Hindawi Publishing Corporation, 2014) Atmaca, Nurgul; Yildirim, Ebru; Guner, Bayram; Kabakci, Ruhi; Bilmen, Fatih SultanWe investigated the protective effects of resveratrol on hematological and biochemical changes induced by fluoride in rats. A total of 28 rats were divided into 4 groups: control, resveratrol, fluoride, and fluoride/resveratrol (n = 7 each), for a total of 21 days of treatment. Blood samples were taken and hematological and biochemical parameters were measured. Compared to the control group, the fluoride-treated group showed significant differences in several hematological parameters, including decreases in WBC, RBC, and PLT counts and neutrophil ratio. The group that received resveratrol alone showed a decrease in WBC count compared to the control group. Furthermore, in comparison to the control group, the fluoride group showed significantly increased ALT enzyme activity and decreased inorganic phosphorus level. The hematological and biochemical parameters in the fluoride + resveratrol treated group were similar to control group. In the fluoride + resveratrol group, resveratrol restored the changes observed following fluoride treatment, including decreased counts of WBC, RBC, and PLT, decreased neutrophil ratio and inorganic phosphorus levels, and elevated ALT enzyme activity. The present study showed that fluoride caused adverse effects in rats and that resveratrol reduced hematological and biochemical alterations produced by fluoride exposure.Öğe Evaluation of oxidative stress, hematological and biochemical parameters during Toxoplasma gondii infection in gerbils(Ankara Univ Press, 2015) Atmaca, Nurgul; Cinar, Miyase; Guner, Bayram; Kabakci, Ruhi; Gazyagci, Aycan Nuriye; Atmaca, Hasan Tarik; Canpolat, SilaThe aim of the present study was to investigate the alterations of oxidative stress, hematological and biochemical parameters in experimental infection caused by Toxoplasma gondii in gerbil. A total of 16 gerbil, 8 of which were control and 8 was infection group, were used in the study. The gerbils were infected by intraperitoneal inoculation of 5000 T. gondii RH strain tachyzoites. In group of, the gerbil were sacrificed at 7th day after inoculation. At the end of this period, blood samples collected and erythrocyte malondialdehyde (MDA) concentrations, superoxide dismutase (SOD), catalase (CAT) activities, plasma aspartat aminotransferase (AST) and alanine aminotranspherase (ALT) activities, total protein, albumin, globulin were determined. Besides, hematological parameters were analysed in whole blood. Aspartat aminotransferase and ALT activities and MDA concentrations and neutrophil percentage and total leukocyte counts increased significantly in infected group when compared to control. In infected group, SOD activities, albumin concentrations and lymhocyte percentage decreased when compared to control. The results of this study suggest that oxidative stress, hematological and biochemical alterations may contribute to the pathogenesis of toxoplasmosis in gerbils.Öğe Heavy metal accumulation and oxidative-antioxidative status in Angora goats depending on age(Parlar Scientific Publications (P S P), 2015) Simsek, Ozkan; Ekici, Husamettin; Cinar, Miyase; Atmaca, Nurgul; Arikan, Sevket; Guner, BayramThis study intends to designate the alterations in the oxidant-antioxidant parameters and the heavy metal concentrations based on age of Angora goats bred in Cankiri-province of Turkey. In order to conduct an analysis of serum heavy metals including aluminum (Al), chromium (Cr), iron (Fe), copper (Cu), cobalt (Co), tin (Sn), cadmium (Cd), selenium (Se), vanadium (V), manganese (Mn), zinc (Zn), lead (Pb), arsenic (As), nickel (Ni), a total of 120 blood samples were taken. Concentrations of plasma vitamin E, vitamin A and beta-carotene, concentration of malondialdehyde (MDA), activities of catalase (CAT) and superoxide dismutase (SOD) were evaluated in the erythrocytes. Correspondingly, compared to young goats, the adult goats had substantially higher levels of Al, V, Mn, Ni, As and Sn. With respect to the young goats, the vitamin E concentration and SOD activity measured in adult goats were lower and the MDA concentration was considerably higher. Consequently, it was seen that aging affected the oxidant-antioxidant parameters and heavy metal concentrations in Angora goats.Öğe Selected haematological and biochemical parameters in healthy Damascus goats(Wiley-Blackwell, 2015) Simsek, Ozkan; Atmaca, Nurgul; Guner, Bayram; Kabakci, Ruhi; Bilmen, Fatih Sultan…
