AbstractThis research was conducted for evaluation of the effect of pollutants of Tigris on some parameters of oxidative stress in common carp. In addition to detection of Glutathione, Malondialdehyde, vitamins E and C and the results were compared with control group. The results revealed that the presence of congestion on blood vessels in kidney with vacuolar degeneration in hepatic cells with infiltration of inflammatory cells and swelling and fatty change in the epithelial cells lining the renal tubules in addition to coagulative necrosis with infiltration of inflammatory cells in the interstitial tissue of kidney. Furthermore fatty change in cardiac muscles with infiltration of inflammatory cells and congestion of blood vessels in heart were observed. The statistical analysis referred to a significant decrease (P≤0.05) in glutathione and increase in the malondialdehyde concentrations levels for the most tissues but there was no difference in E and C vitamins except that of the kidney which show a decrease in C vitamin level. It is concluded from the present study that there is a worse effect of pollutants in river of Tigris on the levels of lipid peroxidation indicators for carp fish tissues naturally exposed to those pollutants which may affects the nutritional and hygienic values of these fishes.
