摘要
本试验研究了溴氰菊酯对草鱼鱼种的急性毒性效应以及溴氰菊酯对草鱼鱼种脑ＡｃｈＥ及ＡＴＰ酶活性的影响。结果表明，溴氰菊酯对规格Ⅰ（平均体重８．２１ｇ）、规格Ⅱ（平均体重６６．６ｇ）草鱼鱼种９６ｈ半数致死浓度（９６ｈＬＣ５０）分别为２．１６μｇ／Ｌ、４．２６μｇ／Ｌ，９５％置信区间分别为１．９３～２．４２μｇ／Ｌ、３．８２～４．７５μｇ／Ｌ，离体条件下对草鱼种脑Ｍｇ２＋－ＡＴＰ酶活性抑制显著，呈一定的浓度－效应关系，回归方程ｙ＝５．８９＋０．３２ｘ（ｒ＝０．９２）；对离体、活体脑ＡｃｈＥ、离体脑Ｎａ＋Ｋ＋－ＡＴＰ酶活性无显著影响。
The
paper studied the acute toxicity of decamethrin on grass carp fingerlings and the effects of
decamethrin on brain AchE and ATPase.The 96hLC50 of type and type fingerlings were 2.16
g/L and 4.26 g/L. The 95 percent confidence limits were 1.932.42 g/L and 3.824.75
g/L.Decamethrin caused significant inhibition of brain Mg2+ATPase activities of grass carp
fingerlings with certain concentrain dependence in vitro. The regression equation was
y=5.89+0.32x and the regression coefficient was r=0.92.There were no significant changes of
brain AchE when grass carp (Ctenopharygodon idellus) fingerlings were exposed to
decamethrin in vivo or in vitro as well as brain Na+K+ATPase in vitro.
