The various membrane abnormalities of sickle erythrocytes may result from excessive accumulation of oxidant damage. We measured the sera levels of malondialdehyde, products of lipid peroxidation, Na+-K+/Mg++ Adenosine 5’ triphosphatase (ATPase) and Ca++/Mg++ Adenosine 5’ triphosphatase, erythrocyte membrane enzymes, in patients with sickle cell anemia and compared their levels with that of normal controls. MDA, Na+-K+/Mg++ and Ca++/Mg++ ATPase levels of control groups were 0.90 ± 0.04 nmol/mL, 168 ± 12.9 and 140.6 ± 8.2 nmol Pi/mg prot/hour, respectively. MDA, Na+-K+/Mg++ and Ca++/Mg++ATPase levels of patients were 2.02 ± 0.01 nmol/mL, 127.0 ± 8.4 and 110.0 ± 9.6 nmol Pi/mg prot/hour, respectively. Our experimental results showed that there was a significant increase in MDA levels of patients with sickle cell anemia as compared with that of the controls. However, erythrocyte membrane Na+-K+/Mg++ and Ca++/Mg++ ATPase levels of patients with sickle cell anemia were significantly lower than the, Na+-K+/Mg++ and Ca++/Mg++ ATPase levels of normal controls. Keywords: MDA, ATPase, Sickle cell.
