A number of functional studies were performed on essentially pure eosinophil preparations obtained from the ascitic fluid of a patient with eosinophilic gastroenteritis. These cells responded to chemotactic factors including a bacterial factor, partially purified C5a, and factors generated from serum or ascitic fluid. The chemotactic activity generated in the patient's ascitic fluid was capable of attracting both neutrophils and eosinophils, was dependent on the presence of complement components, and was identified as C5a. Metabolic studies demonstrated that particle ingestion by eosinophils was associated with a marked increase in hexose monophosphate shunt activity ([1-14C]glucose oxidation), H2O2 formation ([14C]formate oxidation), superoxide anion generation, chemiluminescence, thyroid hormone degradation, iodination, and estrogen binding. This postphagocytic metabolic burst by eosinophils was qualitatively similar to that observed in neutrophils, but for several parameters the eosinophil response was greater than the neutrophil response.
