Abstract

Abstract: With electron paramagnetic resonance (EPR) technique, this paper studied the free radicals generation and oxidative stress in Carassius auratus liver after 4, 8, 12, 24 and 72 hours of 2,4,6-trichlorophenol (2,4,6-TCP) intraperitoneal injection. The results showed that 2,4,6-TCP significantly promoted the generation of free radicals in C. auratus liver. The superoxide dismutase (SOD) and glutathione-S-transferase (GST) activities were induced significantly, while catalase (CAT) activity was inhibited, and glutathione (GSH) content had little difference with the control. A significant increase was observed in the contents of oxidized glutathione (GSSG) and malondialdehyde (MDA).
