We have studied purine metabolism in mononuclear and polymorphonuclear cells from uraemic patients using microradiochemical enzyme assays and high-pressure liquid chromatography. In mononuclear cell lysates the mean activities of adenosine deaminase (EC 3.5.4.4) and 5'-nucleotidase (EC 3.1.3.5) were significantly diminished. The activities of adenylate kinase (EC 2.7.4.3), purine nucleoside phosphorylase (EC 2.4.2.1),
adenine phosphoribosyltransferase
(
EC 2.4.2.7
), and hypoxanthine phosphoribosyltransferase (EC 2.4.2.8) were not significantly different in the two groups. The activities of adenosine deaminase and
adenine phosphoribosyltransferase
were reduced in the polymorphonuclear cell lysates. No clear differences emerged in the concentration of adenine nucleotides in the mononuclear cells. The significance of these changes, which are less marked than those in erythrocytes, is discussed with reference to the immunodeficiency associated with
uraemia
