  • Title: [Immunomodulating activity of p-hydroxyphenyllactic and ascorbic acids].
    Author: Sergeev AV.
    Journal: Biull Eksp Biol Med; 1984 Mar; 97(3):327-8. PubMed ID: 6231064.
    Abstract:
    p-Hydroxyphenyl lactic acid (PHA) in a concentration of 5 . 10(-5) M produced a significant inhibition of cell proliferation in response to alloantigens in a one-way mixed lymphocyte culture (MLC) in colonic cancer patients and in blast transformation in response to suboptimal doses of Con A. Multiple administration of ascorbic acid in an optimal concentration to the culture increased the proliferative response of lymphocytes to alloantigens and Con A. PHA and ascorbic acid did not exhibit any immunomodulating action during the use of healthy donors' lymphocytes or lymphocytes from colonic cancer patients, transformed with optimal mitogen doses. PHA did not affect the production of cytotoxic T lymphocytes in the MLC of the spleens of allogeneic mice but inhibited lymphocyte proliferation in response to alloantigens in the MLC of the spleens obtained from B6 and vitamin A deficient animals.
