摘要:

目的: 探讨除草剂2,4-D丁酯对金鱼血清过氧化物酶(POD)和酯酶(EST)同工酶的影响。方法:根据半数致死浓度,设置0.5、1.0、1.5、2.0 mL/L  4个浓度组及0.9 %生理盐水对照组,每个浓度组按0.1 mL/g腹腔注射金鱼,染毒24 h,断尾取血,离心,取上清液,聚丙烯酰胺方法检测金鱼血清POD和EST同工酶活性,实验数据采用ANOVA分析。结果:与对照组相比,2,4-D丁酯在0.5、1.5和2.0 mL/L浓度时可抑制金鱼血清POD、EST同工酶活性(P<0.05),在1.0 mL/L浓度时可使金鱼血清EST同工酶活性增强(P<0.05)。2,4-D丁酯对EST同工酶迁移率的影响大于POD。结论:2,4-D丁酯对金鱼血清POD和EST同工酶活性均有影响,2,4-D丁酯可改变EST同工酶的迁移率。

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.
