trace metals were measured by neutron-activation analyses in purified nucleic acids and histone ( s ) of lymphocytes from patients with acute lymphocytic leukaemia or infectious mononucleosis and from normal donor dna isolated from lymphocytes of a patient with infectious mononucleosis and a normal donor showed a high a high content of cr2+ , sb2+ , fe2+ , and zn2+ , whereas dna of lymphoblasts from a patient with acute lymphocytic leukaemia had a lower content of these trace metals , but the co2+ content was 20-fold higher than in dna or normal donor lymphocytic cells .
