Resumo
The influence of exogenous triiodothyronine (0.25 ng/mL) on the activity glycosidases (maltase, amylolytic activity) and their sensitivity to Cu, Zn and Pb ions (25 mg/L) has been studied in the whole organism of juvenile blue bream Ballerus ballerus (L.). We have found that the treatment of fish with triiodothyronine resulted in an increase in amylolytic activity. Maltase activity is not affected. In addition, the exposure to exogenous triiodothyronine results in a decrease in the sensitivity of glycosidase to the in vitro action of the ions of biogenic metals Cu and Zn and in an increase in the sensitivity of the maltase to the action of Cu, Zn, and Pb ions.
