title: [Dysfunction of Granulocytes in Children with Frequent Infections].
abstract: Eight children with various diseases, who has frequent infections were examined for abnormalities of serum proteins and leucocyte function. Inborn or secondary defects could be recognized by the tests for chemotaxis, the intracellular killing of bacteria as well as yeast and the oxydative metabolism of the granulocytes. The defects were serum- or cell-dependent and they could be detected alone or in combination with other dysfunctions. Three children showed a reduced stimulation of the lymphocytes in addition to the impairment of chemotactic activity or fungicidal cavity.
