Özet
There have been a considerable number of studies carried out on selenium metabolism in recent years. In most of these studies, selenium has been administered to experimental animals as a selenite ion (Se44) at low concentrations. The aim of the present study was to determine hematological parameters, including total leukocyte number (WBC), erythrocyte number (RBC), hemoglobin amount (HGB) and hematocrit value (HCT), of rainbow trout (Oncorhynchus mykiss Walbaum, 1792) following exposure to sodium selenite and heavy metals (Cd+2 and Cr+3). In addition, biochemical parameters, including blood urea nitrogen (BUN), total protein, albumin, globulin, alkaline phosphatase (ALP), AST (Aspartate Aminotransferase=SGOT; Serum Glutamic-Oxaloacetic Transaminase), ALT (Alanine transaminase=SGPT; Serum Glutamate Pyruvate Transaminase), sodium, potassium, calcium and chloride were determined. The results reported here show that sodium selenite makes an important contribution to antioxidative defense in the rainbow trout. The ability of sodium selenite to protect against oxidative stress induced by heavy metals in fish was discussed.
