MAGNESIUM, ZINC, AND COPPER IN SERUM, ERYTHROCYTE, URINE AND DIALYZATE FLUIDS OF HAEMODIALYSIS PATIENTS

Abstract

Copper (Cu) Zinc (Zn) and Magnesium (Mg) in serum, RBC, urine and dialyzate fluids were studied in 39 patients, who have been undergoing chronic haemodialysis treatment. They were divided in to polyuric , oliguric and anuric depending on their urinary output. Elevated serum and RBC Mg was observed before dialysis, while decreased serum and RBC level was noticed except serum Mg of polyuric patients. Before dialysis elevated serum and RBC Zn were observed. While after dialysis these parameters were increased. Normal RBC Cu value before dialysis was observed. While low serum Cu was noticed. After dialysis serum Cu showed raised value, while RBC level decreased in oliguric and increased in polyuric patients. Zn / Cu ratio found to be high in those patients. All these results were discussed in relation to urine content and also to the dialyzate fluid. Key words: Trace elements, Haemodialysis, Renal failure
