The Effects of Reproduction on Oxidative Stress, vitamins E, A, C and β-Caroten in Capoeta umbla (Heckel, 1843)

Abstract

The aim of this study was to investigate the effect of reproduction on malondialdehyde (MDA), vitamin E (VE), vitamin A (VA),vitamin  C (VC) and β-carotene (βC) levels in tissues (liver, muscle, kidney, spleen and gonad) of sexually matured Capoeta umbla. For this study was determined three different period; before reproduction period (BR), reproduction period (R) and after reproduction period (AR). The VE, VA, VC, βC and MDA in tissues were made using HPLC. Generally, it was determined that levels of VE, VC, VA and βC in gonad was higher in BR and R periods according to AR period, but these levels in other tissues was lower. In addition, it was observed that the kidney tissue affected  least  by the oxidative stress occuring during the reproductive period, significant elevation of MDA levels was observed in other tissues. Furthermore, in this study, MDA levels were found to be higher in females compared to males, especially during the breeding period.
