title: Time-dependent oxidative stress responses of crucian carp (Carassius auratus) to intraperitoneal injection of extracted microcystins.
abstract: This study was conducted to investigate time-dependent changes in oxidative enzymes in liver of crucian carp after intraperitoneally injection with extracted microcystins 600 and 150 microg kg(-1) body weight. The results showed that activities of antioxidant enzymes, including superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase generally exhibited a rapid increase in early phase (1-3 h post injection), but gradually decreased afterwards (12-48 h) compared with the control, with an evident time-dependent effect. These zigzag changes over time contributed a better understanding on oxidative stress caused by microcystins in fish.
