Investigation of Oxidative Stress and Some Antioxidant Levels of Luciobarbus esocinus (Heckel. 1843)

Abstract

In the present study was investigated the effect of reproduction on malondialdehyde (MDA). superoxide dismutase (SOD), reduced glutathione (GSH) and glutathione peroxidase (GSH-Px) levels in tissues (liver, muscle, kidney, spleen and gonad) of sexually matured Luciobarbus esocinus. For this study was determined three different period; before reproduction (BR) period (February), reproductive (R) period (May) and after reproduction (AR) period (August). Generally, the MDA value of all tissues increased during the reproductive period. It was determined that levels of SOD changed in tissues of female and male in all periods. In the GSH-Px and GSH activity of kidney and muscle tissues were not effected by the reproduction periods. Especially, statistically significant changes were detected in the analysed oxidant and antioxidant parameters of liver and gonad tissues during the reproduction periods.
