The Determination of Some Biochemical Parameters in the Tissues of Luciobarbus esocinus (Heckel, 1843) in the Reproductive Period

Abstract

In the present study was investigated the effect of reproduction on oxidative stress (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 Luciobarbus esocinus in three different period. These periods was defıned as before reproduction period (A), reproduction period (B) and after reproduction period (C). The VE, VA, VC, βC and MDA levels in tissues were made using HPLC. As a result of these analyzes, it was seen that levels of VE, VC, VA and βC in gonad was higher in A and B periods according to C period, but these levels in other tissues was lower. It was identified according to the results of the analysis that the decrease in the amount of VA in the tissues in general was higher than βC.  In addition, it was determined that the kidney tissue affected least by the oxidative stress occuring during the reproductive period. But, 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 reproduction period.
