In this work we studied in vitro and in vivo the protective effect of captopril on the deleterious effect of Hg(++)-induced nonspecific membrane permeability changes to Ca++ and membrane de-energization. In vivo the administration of captopril prevented the toxic effects of mercury poisoning on membrane permeability, oxidative phosphorylation and Ca++ homeostasis. Moreover, captopril preserves kidney tissue morphology from Hg(++)-induced damage. The protective effect of captopril is most likely related to the existence of a sulfhydryl group in the drug. ER -
