Ecstasy-induced very severe aplastic anaemia complicated by invasive pulmonary mucormycosis treated with allogeneic peripheral blood progenitor cell transplant.

Very severe aplastic anaemia (vSAA) is rare. We report a case of Ecstasy-induced very severe aplastic anaemia which did not respond to immunosuppressive therapy, developing invasive pulmonary mucormycosis. The patient underwent an HLA-identical sibling peripheral blood progenitor cell transplant (PBPCT) with rapid neutrophil engraftment. During engraftment he developed life-threatening adult respiratory distress syndrome (ARDS). This case serves to illustrate a novel aetiology of vSAA where the infective complications responded to prompt haematopoietic engraftment.

Floral expression of a gene encoding an E2-related ubiquitin-conjugating protein from Arabidopsis thaliana.

An Arabidopsis thaliana gene (UBC6) encoding a homologue to ubiquitin-conjugating enzymes has been isolated which is capable of encoding a protein of 183 amino acids of ca. 21 kDa. Northern analysis indicates that the gene is expressed in flowers, seeds and, to a somewhat lesser extent, in 10-day seedlings but not in mature leaves, callus and pre-flowering plants. This pattern of expression is confirmed using transgenic Arabidopsis plants containing a UBC6 promoter-GUS gene fusion construct. These plants display GUS activity in mature anthers prior to dehiscence, in developing embryos, sepals and the style after pollination.
