Abstract:
Animal mast cell models demonstrate direct histamine release by protamine. Investigators have proposed that protamine also releases histamine in man. We studied the effects of protamine alone and heparin-protamine mixtures on minced lung tissue for evidence of histamine release. We were unable to demonstrate the release of histamine despite positive anti-IgE controls. Nonimmunologic histamine release from human lung appears unlikely as a mechanism for protamine reactions in man.
