Inbred mice--C57BL, A, C57BR, C3H and CBA strains with a high, medium and low response to sheep red blood cells (SRBC) were injected with polymeres--poly-4-vinylpyridine (P-4-VP) and polyacrilic acid (PAA), and were immunized with SRBC; production of antibody-forming cells in their spleen was determined. It was shown that the administration of P-4-VP to C57BL mice was followed by a 5--fold increase of the immune response and injection of PAA--by a 4-fold increase. Injection of P-4-VP and PAA to CBA mice increase the immune response 2.5- and 2.8-fold, respectively. In the C57BR mice P-4-VP increased the immune response 4 times, and PAA--4.7 times. Treatment of C3H mice with P-4VP was followed by a 2-fold and with PAA by a 2.4-fold increase of the immune response. Injection of P-4-VP and PAA to CBA mice had no effect on the immune response. Thus, with the increase of the immunological reactivity to sheep erythrocytes in the mentioned strains of mice there was observed a reduction of the enhancing effect of the polymeres to the immune response.
