title: The observation of complement activation and polymorphonuclear neutrocytopenia during cardiopulmonary bypass.
abstract: By determining the plasma levels of C2, C4, factor B and polymorphonuclear neutrophils (PMNs) of the patients who received CPB, the path of complement activation and changes of PMNs were studied. The results suggest that complement system was activated through alternative pathway during CPB and was activated through classic pathway after CPB. The anaphylatoxin, the products of complement activation may be responsible for the polymorphonuclear neutrocytopenia.
