摘要: Equitoxic doses of 5-(3-3-dimethyl-1-triazeno)imidazole-4-carboxamide (DTIC) and aryl-triazene derivatives (compounds all capable inducing a marked increase in murine tumor cell immunogenicity) were studied for their effects on the host immune system. At different times after drug exposure animals tested allograft responses, competence producing lymphocytes active lethal graft-versus-host disease, delayed-type hypersensitivity, humoral antibody production, mitogen responsiveness. While some aryl-triazenes (DM-COOK DM-NO2) showed pattern immunodepression similar to that DTIC, others less (MIC, MM-COOK, MM-Cl) or far (DM-Cl, MM-NO2) than DTIC impairing immunocompetence, although retained even augmented ability induce chemical xenogenization.
