摘要: The in vitro metabolism of tributyltin (TBT) and triphenyltin (TPT) by the hepatic microsomal cytochrome P-450 system enzymes of Dall's porpoises (Phocoenoides dalli) was comparatively elucidated with those enzymes of the Sprague Dawley rat in the present study. Our results suggested firstly a limited metabolic capacity for TBT and especially TPT to their metabolites in the Dall's porpoises, and documented a similar mechanism of a relatively stronger metabolic rate of TBT to its metabolites than that of TPT in the micro-some of porpoises and rat. However, the metabolic capacity to degrade both TBT and TPT were much lower in the microsome of porpoises than that in the rats.
