title: [The effect of heparin and a human heparin precipitable plasma fraction on antibody producing cells in vitro].
abstract: A study was made of the effect of heparin and heparin-precipitable fractions of human blood plasms (HPF) on the capacity of the cells of mouse spleen immunized with sheep erythrocytes to plaque-formation in vitro. It was found that heparin and HPF produced an inhibitory effect on the reaction of plaque formation as a result of interaction with lymphocytes. It is supposed that a possible point of application of heparin and HPF action are surface cell membranes of the antibody-forming cells.
