The present invention relates to biologically-active copolymers and to compounds that can be safely used to cause the thymus of an animal or human to increase in size, thereby replenishing the T-lymphocyte population. When injected into an animal or human with an antigen, certain of the biologically-active copolymers cause immunosuppression to the antigen. When injected into poultry, certain of the biologically-active copolymers modulate immune responsiveness. The biologically active copolymers are also useful as growth promoters for animals. Compounds within the biologically-active copolymers of the present invention are effective tumoricidal agents. At low concentration, certain of the biologically-active copolymers can cause dedifferentiated cells to differentiate. The biologically-active copolymer of the present invention is a safe and non-toxic formulation that can effectively be administered to animals or humans. The biologically-active copolymer can be mixed in an oil and water emulsion and administered to an animal or human by injection or by oral administration.
