RESUMO

Mancozeb is a fungicide of the ethylene bisdithiocarbamate (EBDC) class complexed to the metals manganese and zinc. Nabam is the sodium salt of the EBDC backbone. The purpose of this study was to determine if these EBDC compounds alter essential metal homeostasis and glutathione status in Sprague-Dawley rats. Our findings indicate EBDCs caused accumulation of copper in kidneys, but not liver. EBDC compounds also increased glutathione reductase activity in liver, but not kidneys, whereas only mancozeb increased glutathione peroxidase activity in the liver. Mancozeb and nabam increased total glutathione in liver, but only mancozeb increased total glutathione in the kidney. Neither mancozeb nor nabam altered glutathione ratio in either liver or kidney compared to control. Our data suggest that the EBDC backbone of mancozeb, and not the zinc or manganese moieties, is responsible for changes in glutathione status and alteration of essential metal homeostasis in rat liver and kidney.
