| Abstract: | Five Swiss subjects with hereditary acatalasemia (4 homo-, 1 heterozygous) were studied by a series of neutrophil function tests. H2O2 was added to a polymorphonuclear neutrophil leukocyte-suspension to produce a metabolic stress; neutrophil functions related to membrane deformation were subsequently found to be depressed, i.e., chemotaxis, membrane potential, and chemiluminescence. This mechanism might be one pathogenetic factor in the formation of mucosal ulcers in acatalasemic individuals. |
