Abstract :
Background: 5 -Nucleotidase (5 -NT) is an established plasma membrane marker in many mammalian cells where the enzyme presents a~ an ectoenzyme and has its active site facing the external medium. The leukemias are the most common form of childhood cancer. They account for about one third of new cases of cancer diagnosed each year. The acute lymphocytic leukemias make up about 76% of cases, with a peak in incidence around the age of 4 yr. Serum 5 -NT activity varies between different children with leukemia. Activities of this enzyme were determined in sera from 25 cases of normal children ,21 children with ALL, 5 children with NHL,4 children with ANL, and one case with CML.
