两种菊酯类农药对鲤血清溶菌酶和转氨酶的影响

Effects of two Pyrethrin Pesticides on Serum Lysozyme and Glutamic Pyruvic Transaminase in Common Carp

采用肌肉注射法研究不同浓度的高效反式氯氰菊酯和功夫菊酯对鲤血清溶菌酶、转氨酶的影响。试验结果表明:高效反式氯氰菊酯低浓度(6、60μg/kg)短时间(24、48 h)作用使溶菌酶活性显著升高(P<0.05),但低浓度长时间(96、168 h)作用及高浓度(600、6000μg/kg)各采样点(24、48、96、168 h)作用则使其活性下降,各浓度组在168 h采样点抑制酶活力与对照组相比差异均达极显著(P<0.01)。功夫菊酯各浓度组在各采样点抑制酶活力均达极显著(P<0.01)。转氨酶则随两种攻毒农药浓度增大、作用时间延长活性均呈升高趋势,各浓度组与对照组比较酶活力升高均达极显著(P<0.01)。

Effects of beta-cypermethrin and cyhalothfin on activities of serum lysozyme （LSZ） and glutamic pyruvie transaminase （GPT） in common carp （Cyprinus carpio L） injected at a dose of 6, 60,600, 6000μg/kg were determined 0, 24, 48, 96 h, and 168 h after administration. The results showed that the GPT activity increased significantly at high dose of beta-cypermethfin and cyhalothfin and prolonged administration （ P 〈 0.01 ）. The LSZ activity increased significantly at low dose of beta-cypermethfin （6 μg/kg and 60μg/kg） 24 h and 48 h after administration（ P 〈0.01 ）, but decreased significantly at high dose of beta-cypermethfin （600 μg/kg and 6000 μg/kg） 24 h and 48 h, 96 h and 168 h after administration （ P 〈0.01）. For cyhalothrin, the LSZ activity decreased significantly at all dose and various periods after administration.
