Ultrathin sections containing Auer rods from cases of acute myeloblastic leukaemia (AMyL) were tilted in the goniometer stage of the electron microscope and the resulting series of electronmicrographs analysed in an optical diffractometer illuminated by laser. The results showed that Auer rods of AMyL show a truly three dimensional crystal structure. Measurements from the optical diffraction pa...

The BCR/ABL1 fusion gene, usually carried by the Philadelphia chromosome (Ph) resulting from t(9;22)(q34;q11) or variants, is pathognomonic for chronic myeloid leukaemia (CML). It is also occasionally found in acute lymphoblastic leukaemia (ALL) mostly in adults and rarely in de novo acute myeloid leukaemia (AML). Array Comparative Genomic Hybridization (aCGH) was used to study six Ph(+)AML, th...

Background: Metronomic chemotherapy is based on antiangiogenic and immunologic mechanisms obtained by the administration of traditional cytotoxic drugs at lower concentration without rest periods. The low dosage induces fewer or no side effect compared to classic maximum tolerated dose administration (MTD). At present, no treatment related acute leukaemia was reported in cyclophosphamide-based ...

OBJECTIVE To investigate whether risks of leukaemia are related to occupational exposure to magnetic fields. METHODS The mortality experienced by a cohort of 83 997 employees of the former Central Electricity Generating Board of England and Wales was investigated for the period 1973-97. All employees were employed for at least 6 months with some employment in the period 1973-82. Computerised ...

A cytochemical study of the lysosomal enzyme beta-glucuronidase in 60 cases of acute leukaemia has shown a qualitative difference in the cytoplasmic distribution of the enzyme between blast cells of the lymphoid and myeloid cell series. This difference provides a useful additional method for cytochemical classification of cell type and is superior in this respect to the other lysosomal enzymes ...

The work reported in this paper was an attempt to elucidate the pathology of a case of acute leukaemia in a workman engaged in an operation which exposed him to a notable inhalation of benzene vapour. Chronic intoxication with benzene is classically regarded as a cause of aplastic anamia, but the fact that atypical cases arise referable to the same cause has made it necessary to extend the toxi...

The lung function of 21 patients with leukaemia (11 with acute myeloid leukaemia, six with acute lymphatic leukaemia, four with chronic myeloid leukaemia) and of five with severe aplastic anaemia was tested before and after allogenic bone marrow transplantation. Vital capacity (VC) was lowered in patients with leukaemia before transplantation. VC and FEV1 fell significantly after transplantatio...
