The effect of zinc on the toxic action of lead after administration of ethanol to rats.

The aim of this paper was to investigate if zinc may counteract toxic symptoms of poisoning with lead and ethanol in rats, reflected by some biochemical changes in the blood. Wistar rats received lead in drinking water (500 micrograms/ml) for 6 weeks, followed by zinc (240 micrograms/ml) for 2 weeks. During the last 108 h of the experiments the rats received every 12 h an intragastric dose of 5 g/kg of ethanol.

The interactions of copper, lead and ethanol in rats: effects on some biochemical parameters of blood.

The aim of this paper was to investigate the action of copper on some biochemical parameters of blood of Wistar rats exposed to a combined action of lead and ethanol. The animals received lead in drinking water (500 micrograms/ml) for 6 weeks, followed by copper (12 micrograms/ml) for 2 weeks. During the last 108 h of the experiments the rats received every 12 h an intragastric dose of 5g/kg of ethanol.
