title: [Mast-cell rosettes in the immunized rat].
abstract: After stimulation by ovalbumin + Bordetella pertussis, rat peritoneal mast cells can form rosettes with antigen-coated erythrocytes. This phenomenon is inhibited by previous incubation of mast cells with antigen; it is attributed to apparition of membrane-bound anaphylactic antibody. The variations of percentage of rosette forming mast cells during the course of immunization are reported and compared with P.C.A. titers.
