[Action of the polytissular antitoxic principle (PATP) on the genitically leukemic AKR mouse treated by para-di(2-chloroethyl)-L-phenylalanine (PDCPA)].

An antitoxic polytissular principle extracted from various tissues, improves the survival time of the AKR genetically leukemic mouse and protects it against the toxicity of an antimitotic, the para-di-(2-chlorethyl)-1-phenylalanine, used in leukemia and myelomae.
