INVESTIGATION OF ANTIOXIDANT COMPOUNDS IN FLUOROTIC SHEEP

Abstract

Abstract Fluorosis, a condition which usually affects the formation of bone and teeth in human and animals, is an important health problem in Van and Agri provinces. This study was performed to determine the levels and the changes of antioxidant compounds in fluorotic sheep. 30 fluorotic sheep and 20 healthy Morkaraman sheep of 3-4 years old were used as living research materials. The diagnosis of fluorosis was confirmed by clinical examinations. The urine fluoride level was determined. Blood of all animals was taken from vena jugularis by appropriate techniques and analyzed for glutathione peroxidase (GPx), glutathione (GSH), superoxide dismutase (SOD), malondialdehyde (MDA), sialic acid (SA) and lipid-bound sialic acid (LSA). The levels of these parameters in healthy and fluorotic group were: 1028-416.8 mU /ml, 23.23-50.16 mg/ dl, 9.25- 7.88 mU/ ml, 1.62-0.56 nmol/ ml, 51.19-46.33 mg/ dl and 9.77- 12.16 mg/dl, respectively. Urine fluoride (F) levels were 1.65 ppm in healthy and 23.84 ppm in fluorotic sheep groups. Statistical differences was found between the average values of healthy and fluorotic groups as p? 0.0001 in GPx and GSH, p?0.001 in MDA, p?0.05 in SA, p?0.01 in LSA and p?0.001 in urine F levels. No statistical differences were found in SOD levels. (p?0.05) The results obtained in this study indicate that important changes were found in antioxidant systems of fluorotic sheeps.
