Renal lesions and tissue concentrations of zinc, copper, iron and manganese in experimentally zinc intoxicated sheep.

Renal lesions were produced in three out of 10 sheep dosed with large quantities of zinc for two to 14 weeks. Administration of the zinc resulted in significant increases in the concentrations of zinc in the kidneys, liver and pancreas, and of copper and iron in the kidneys and pancreas, and a significant decrease in the concentration of manganese in the pancreas. The sheep with kidney damage had increased plasma creatinine concentrations and significantly higher mean concentrations of zinc in their livers and pancreases, and of copper and iron in their kidneys, than the sheep with no kidney damage.
