A substance inhibiting Escherichia coli motility was isolated by "motilometry" assay from the culture broth of Streptomyces sp. strain NR9GG8 and was found to be identical with desferrioxamine B. Its inhibitory effect was reversed by cyclic adenosine 3',5'-monophosphate (cAMP), while the motility stimulation by cAMP was diminished by this inhibitor. Its effects on various enzymes involved in cA...

Background Combination therapy with deferipron and desferrioxamine (DFP+DFO) seems more effective than DFP and DFO in monotherapy in removing myocardial iron. However, no data are available in literature about prospective comparisons on cardiac iron and function in TM patients treated with DFP+DFO versus DFP and DFO in monotherapy. Aim: The aim of this multi-centre study was to assess prospecti...

Septicaemia occurred after accidental oral overdoses of iron in two previously healthy children. Yersinia enterocolitica serotype 0:3 was recovered from blood and stool cultures in both patients. Enhanced growth of Y enterocolitica in the intestine combined with damage of intestinal mucosa may have been of major importance for the development of generalised infection in these cases. Iron and th...

Cardiac failure or arrhythmia are the dominant causes of death in patients with thalassaemia major and other transfusion-dependent refractory anaemias. Each unit of blood contains 200–250 mg of iron and body iron stores are normally only 0·5–1·5 g. Since the body has no physiological mechanism for excreting iron, repeated blood transfusions result in iron accumulation in the reticuloendothelial...
