The Ca2+-induced expression of the primary response genes egr-1 and c-fos was investigated in the murine erythroleukaemia cell line ELM-I-1. Exposure of the cells to the Ca2+-ionophore A23187 led to a rapid transient rise in egr-1 and c-fos mRNA production followed by an increase in Egr-1 and c-Fos protein levels as well as an increase in Egr-1 and activator protein 1 (AP-1) DNA-binding activit...

Zygomycosis is not often diagnosed in the United Kingdom, and so the possible importance of the findings in a patient with disseminated zygomycosis who had been treated with chemotherapy for erythroleukaemia was not appreciated until histological examination of specimens obtained at necropsy provided a presumptive diagnosis. No attempt had therefore been made to identify the organism by culture...

Pyoderma gangrenosum at the site of sternal marrow aspirate was observed in a patient with acute myeloproliferative disease characterized by a high peripheral blood basophilia. Lesions with a similar appearance were also seen on the palate. No other disease known to be associated with pyoderma gangrenosum could be demonstrated. A review of the literature suggests that myeloproliferative disease...

NK cell cytotoxicity against the erythroleukaemia cell line K562 was studied, during and after the in vitro exposure to clinically-used concentrations of the general anaesthetic agents nitrous oxide, halothane and enflurane. Each of these agents produced a dose-dependent reduction in cytotoxicity. At approximately equipotent doses nitrous oxide produced less suppression than either halothane or...
