Effects of Reproduction on Oxidative Stress and Some Antioxidant Levels in tissues of Capoeta umbla (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 Capoeta umbla. For this study was determined three different period; before reproduction (X) period (February), reproductive (Y) period (May) and after reproduction (Z) period (August). Especially, statistically significant changes were detected in the analysed oxidant and antioxidant parameters of liver and gonad tissues in the X and Y periods compared with the Z period. Generally, the MDA value of all tissues increased during the reproductive period. It was determined that levels of SOD changed in both sexes in all periods. The GSH-Px and GSH activity of kidney and muscle tissues were not effected by the reproduction periods.
