title: [A method for the experimental determination of the doses of antigen protecting 50% of animals from a series of doses of pathogenic material].
abstract: A new immunological regularity has been discovered mathematically. Proceeding from this regularity, a simple index characterizing the pathological reactivity of animals has been proposed and a new (universal) method for the determination of the D50 of the antigen, i. e. doses protecting 50% of the animals receiving a series of doses of pathogenic material, has been developed and checked according to experimental data.
