<p>This invention relates to biologically active copolymers and compounds which can safely be used to increase the size of the thymus in an animal or a human being, thus resupplying the population of T-lymphocytes. When injected into an animal or human being with an antigen, the biologically active copolymers produce immunosupression of the antigen. The biologically active copolymers are also useful as growth promoters in animals. The compounds with biologically active copolymers according to this invention are effective tumoricidal agents. The biologically active copolymer according to this invention is a formulation which offers safety and is non- toxic and can be effectively administered to animals or human beings. The biologically active copolymer can be mixed in oil and water emulsion and administered to an animal or human being by injection.</p> |
