title: Asimple test for immunogenicity of colloidal infusion solutions- the draining lymph node activation.
abstract: The increasing number of lymphocytes with nucleoli synthesizing RNA in the mouse lymph nodes, draining the site of injection of infusion solutions, was used as a marker for their immunogenicity. The percentage of "active" lymphocytes significantly increased 3 days after the administration of preparations based on bovine serum or human haemoglobin which were found immunogenic when testing for antibody formation. Such a reaction was not elicited in mice treated with Physiogel, Dextran and Duxon which do not cause any production of antibodies. The described test may serve as a rapid and economical assay for the immunogenicity of infusion solutions and other substances.
