Influence of season and pollution on the antioxidant defenses of the cichlid fish acará (Geophagus brasiliensis) [PDF]

Brazilian Journal of Medical and Biological Research, 2001
The livers of Geophagus brasiliensis collected from both a non-polluted site and a polluted site were analyzed for different antioxidant defenses, O2 consumption, thiobarbituric acid-reactive substance (TBARS) levels, and histological damage. Compared to controls (116.6 +/- 26.1 nmol g-1), TBARS levels were enhanced at the polluted site (284.2 +/- 25.6
