Abstract：Effect of perchloroethylene (PCE) on superoxide dismutase systems (SOD) and peroxidase (POD) in grass carp’s hepatopancreas, kidney and gill tissue was investigated. The result shows: the activity of SOD in hepatopancreas represent ‘increase and then decrease’ [72h SOD was (6665.84±106.87)U/g·FW,168h SOD was (3021.26±16.96) U/g·FW] under the stress of PCE at low concentration and ‘increase then decrease and increase again’ [24h SOD was (2175.16±185.14)U/g·FW, 96h SOD was (5692.19±44.17)U/g·FW,168h SOD was (1297.70±11.52) U/g·FW] under the stress of PCE at high concentration; the activity of SOD in kidney represent ‘decrease and then increase’ at any concentration of PCE; the activity of SOD in gill tissue does not change much except at low concentration of PCE within a short time, the activity always decreases under other circumstances. The activity of POD in hepatopancreas always decreases under the stress of PCE at low and moderate concentration and ‘decreases then increases and decreases’ at the stress of relatively low and high concentration of PCE. The activity of POD in kidney ‘increases, decreases, then increases and decreases’ at low concentration of PCE and ‘decreases and increases then decreases’ at high concentration. The results indicate that the activity of SOD and POD in grass carp’s gill tissue is much lower than SOD and POD in hepatopancreas and kidney.
