β¦ Synopsis
Serum concentrations of lactate dehydrogenase (LDH), alpha-hydroxybutyrate dehydrogenase (HBD), phosphohexose isomerase (PHI), leucine aminopeptidase (LAP), beta-glucuronidase (beta-gluc) and angiotensin-converting enzyme (ACE), were measured in 107 cases of untreated acute myeloid leukaemia which were classified by morphological, immunological and cytochemical criteria. The results show that serum LDH was increased in most cases, irrespective of leukaemic subtype, serum PHI and LAP were significantly higher in monocytic variants and serum beta-gluc and ACE levels were generally within normal limits. In addition, significant (p less than 0.05) relationships were found between serum LDH, PHI, LAP and beta-gluc concentrations and the numbers of circulating leucocytes.

A total of 412 cases of acute leukaemia were examined for the presence of nuclear terminal deoxynucleotidyl transferase (TdT) by indirect immunofluorescence. Of the 129 cases of acute myeloblastic leukaemia (AML FAB groups M1/M2) examined, 18% (n = 23) had significant proportions (greater than 10%)
## Abstract Chromosome analysis in two cases of acute myeloid leukaemia are reported. On the basis of slight aberrations in the banding pattern marker chromosomes were observed in both cases. In one case a widened Cβband of an additional D chromosome, and in the other case an unusual negative fluor
