[Experimental allergic encephalomyelitis as a model for the study of therapeutic concepts for encephalomyelitis disseminata].

The induction of immunological tolerance with, and for, the caused organotypical antigen is a conception for a specific therapy for neuroimmunological diseases with at least a partial autoallergic pathogenesis. Appropriate to a set step-by-step programme for the development of antigen-specific therapy preventive tolerance experiments were carried out at the model of experimental allergic encephalomyelitis (EAEM) with allogenic myelin basic protein (BP) prepared from rabbits. The result is: 100 ug BP given intravenously simultaneously with 100 ug BP in incomplete Freud's adjuvant given intracutanously twice a week and 40 mg Cyclophosphamid given daily during the minor clinical incidence rate and no signs of EAEM pathomorphologically. A longlasting tolerance for the BP could be obtained as a test proved after 100 days. Hints are given for further potential therapeutic treatments, such as the use of antigen bound chemically to the immunosuppressive drug or the use of chemically modified BP for the induction of a specific tolerance.
