Hidalgo Ernesto Fernández Alicia Cabello Cristian Rivas Flavia Fontecilla Lorena Morales Alvaro Aguirre Enrique Cabrera Ciencias de la Tierra catalase superoxide dismutase reactive oxygen species total antioxidant capacity Oxidative stress is the damage at cellular, tissue or organic level produced by reactive oxygen species, that are produced as a result of the exposition to polluting agents, the ingestion through diet, UV radiation or to the oxygen metabolic processes. Chiton granosus is an intertidal organism abundant in Valparaíso, region of Chile. The objective of studying this species, by its abundance, is oriented to its use as biomarkers of oxidative polluting agents and so to evaluate its possible role as a monitoring species of the presence of these polluting agents. To evaluate, gonads, radular and digestive systems were analyzed from Chiton granosus collected from Torpederas, a highly polluted public sector, and Montemar (control area). Two hundreds and fifty nine individuals of Chiton granosus were collected; 133 from Torpederas and 126 from Montemar. The results indicate that no differences due to the sex exists in enzyme activity: catalase in the gonads, superoxide dismutase (SOD) in the radular and digestive systems. No influence of the sampling site was observed, nevertheless the lipoperoxidative damage was concordant with a greater oxidation level in females in the more polluted sector. Total antioxidant capacity exhibited significant differences due to sex and oxidative pollution. 2006 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47941203 es http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.2 Vol.41 |
