| Popis: |
The inducibility of the freshwater crayfish (Astacus astacus) bio-transformation enzymes with model inducers (Aroclor 1254, β-Naphthoflavone, Phenobarbital) were investigated three days after intra cephalothoracic injection in the fasting crayfish at 5 °C. Of the monooxygenase activities, 7-ethoxycoumar in 0-deethylase increased in the hepatopancreas significantly (p < 0.05) after s-naphthoflavone administration. Benzo(a)pyrene hydroxylase did not change. Aroclor 1254 and phenobarbital injection elevated hepatopancreatic glutathione S-transferase activity (p < 0.05). |
