Abstract
Estimation of copper, zinc, calcium and magnesium was done in plasma, erythrocytes and urine of twenty patients with chronic renal failure of diverse aetiologies. Twenty normal individuals formed the control group. Significant plasma hypozincaemia and hypozincuria was observed in uraemic patients, though the concentration of zinc in erythrocytes was significantly higher than in controls. The copper content of the erythrocytes was significantly higher in patients when compared to controls, while the reverse was true for its excretion in the urine. The increased level of copper in the erythrocytes showed a correlation with increasing severity of renal failure. Significant hypocalcaemia was seen in the erythrocytes and plasma of uraemic patients, though magnesium level was elevated. Urinary excretion, however, of both calcium and magnesium were markedly reduced in these patients. The magnesium levels in plasma and urine showed a significant correlation with the severity of renal failure.
