Nickel toxicity and interactions of nickel with zinc, copper and lead were studied in growing chicks fed supplement diet. Feed intake and growth rate of the chick were reduced by 250 mg nickel as a sulfate salt per kg of feed. The toxicity of nickel was decreased by zinc or copper supplementation, but not lead. High nickel feed increased nickel level in kidney and decreased zinc levels in tibia and plasma. However, low zinc levels in tibia and in plasma were reversed by zinc supplementation. Hemoglobin, packed cell volume, and aortic elastin content were increased in chicks fed nickel

This study was designed in order to clarify the effect of ethanol drinking on the mineral contents on liver, kidney, muscle and hair. Forty-five rats were divided into 2 groups and a control group. The control group received tap water and the other 2 groups were given 8 % and 40 % ethanol as drinking source. Liver, kindney, muscle and hair samples were taken and analyzed for zinc, calcium and copper contents by atomic absorption spectrophotometric methods. The zinc content of muscle showed significant (P0.01) decrease in both groups. The calcium content of hair showed significant (P0.1) increase in 8 % ethanol group. The copper contents of kidney and muscle in 8 % ethanol group and liver in 40 % ethanol group showed significant (P0.1) decrease
