丁草胺与胡子鲶肝胰脏淀粉酶及脂肪酶活力的影响

Effects of Butachlor on Hepatopancreatic Amylase and Lipase Activities in Clarias fuscus

本实验研究3种不同浓度(0.1、1.0、2.5 mg/L)的丁草胺对胡子鲶肝胰脏淀粉酶、脂肪酶活力的影响.结果表明,暴露2 d的高浓度组(2.5 mg/L)及暴露4 d的各浓度组淀粉酶活力显著提高,暴露6d的低浓度组(0.1 mg/L)及较高浓度组(1.0 mg/L)仍保持激活特性,而高浓度组(2.5 mg/L)淀粉酶活力则受到显著抑制;丁草胺暴露期间胡子鲶肝胰脏脂肪酶活力始终呈现显著的抑制作用,特别是高浓度组(2.5 mg/L)随着暴露时间的延长(6 d)则呈现极显著抑制.

In this investigation,we studies the influence of butachlor at different concentrations level（0. 1,1.0 and 2. 5 mg/L）on digestive enzymatie aetivities in eatfish（ Clarias fuscus ） during hepatopanereatie 6 day experiment. The results shows that the amylase activity increases only in the 2. 5 mg/L butaehlor treated group on the second day. And on the 4th day, all of the treated groups exhibits enhaneed amylase aetivity. On the 6th day, the amylase enzymatie aetivity is still indueed in both of the lower eoneentration （0.1 and 1.0 mg/L） groups, but in the 2.5 mg/L eoneentration group the enzymatie aetivity is signifieantly inhibited. Aetivity of lipase is signifieantly inhibited by butaehlor at 0.1, 1.0 and 2.5 mg/L eoneentrations during the experiment.
