مقاله Antioxidant enzymes in the liver of Chelidonichthys obscurus from the Montenegrin coastline : تی پی بین

خلاصه مقاله

The activities of antioxidant defence enzymes — total, manganese and copper zinc containing superoxide dismutase (Tot SOD, Mn SOD, CuZn SOD), catalase (CAT), glutathione peroxidase(GSH-Px), glutathione reductase (GR) and biotransformation phase II enzyme glutathione-S-transferase (GST) — in the liver of longfin gurnard (Chelidonichthys obscurus) from the Montenegrin coastline (Adriatic sea) were investigated. The specimens were collected in winter (February) and late spring (May) at two localities: Platamuni (PL, potentially unpolluted) and the Estuary of the River Bojana (EB, potentially polluted). The obtained results show that the activities of Mn SOD, CAT,GSH-Px and GST in winter were significantly lower at EB than at PL. In spring, the activities of CATand GST were decreased, while GR activity was increased at EB in comparison to PL. The activities of Mn SOD and GST at PL were decreased and GSH-Px, GR and GST activities at EB were increased in spring compared to winter. Our work represents the first study of liver antioxidant enzymes of longfin gurnard from the Montenegrin coastline and reveals that locality, as a variable, has a greater influence on antioxidant enzymes and biotransformation phase II enzyme GSTactivities compared to season.

Central European Journal of Biology (CEJB) is an English-language journal devoted to rapid publication of original research and review articles in all biology fields. The aim of this journal is to become the premier source of high quality research from Central and Eastern Europe; however, contributions are welcome from all over the world. The journal is published bimonthly. Central European Journal of Biology presents rigorously peer-reviewed scientific articles in the following categories: Research Articles, Communications, Reviews and Mini-Reviews, Commentaries and Letters to the Editor. Coverage includes Cellular and Molecular Life Sciences, Biomedical Sciences, Plant Sciences, Animal Sciences and Evolution, Ecology Environment. The aim of the editors is to publish timely, useful and informative results that will be of value to a general biological audience. We provide free language assistance to the authors of all accepted articles. Every article published in our journal is promoted to researchers working in the respective field.
