| Abstract: | 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. |
