Characterization of Smed-AChE activity in planarian homogenates. Evaluation of Smed-AChE inhibition by insecticides and the associated enzymatically-generated degradation products in planarian homogenates. Blue and red bars represent the inhibition of Smed-AChE by insecticides and their degradation products respectively for paraoxon-ethyl (a), parathion-ethyl (b), diazinon (c) and fenitrothion (d). The values represent the mean ± SD (standard deviation) of three replicates. Black stars (*) indicate a significant difference between insecticide and degradation product for a given concentration (one star to indicate p < 0.05; two stars to indicate p < 0.005; three stars to indicate p < 0.0005 according to Student’s t-test).
