Abstract:

OBJECTIVE: To explore the effect of herbicide 2,4-D butyl ester on the expressions of peroxidase (POD) and esterase (EST) in Carassius auratus serum. METHODS:0.5,1.0,1.5,2.0 mL/L concentrations of 2,4-D butyl ester (according to its 24 h LC50) and 0.9% saline control group were prepared.  Carassius auratus received intraperitoneal injection of 0.1 mL/g dose of each concentration. Tail blood of Carassius auratus and the supernatant of centrifugation were collected after 24 h. SDS-polyacrylamide gel electrophoresis was used to test the toxicity on POD and EST.  The experimental data were analysed with ANOVA.  RESULTS:POD and EST enzyme activities were inhibited at low concentrations(0.5 mL/L),induced at medium concentrations(1.0 mL/L) and decreased at high concentrations (1.5,2.0 mL/L). Compared with the control group. the effect of 2,4-d butyl ester on migration rate of EST isoenzyme was greater than POD.  CONCLUSION:2,4-D butyl ester affected the activities of POD and EST in Carassius auratus and  2,4-d butyl ester changed the EST isoenzyme mobility.
