Induction of a protective immune response in rats by injection of live or killed S. mansoni worms.

abstract：:Factors governing the sensitization or desensitization of basophils and mast cells are discussed. Mathematical models are proposed which illustrate the effects of rising or falling specific or non-specific IgE titres on the tendency of these cells to degranulate. The models presented are consistent with the hypothesis...
