title: [Effect on helper activity of synthetic polyelectrolytes introduced into an in vitro system of interacting macrophages and thymus cells].
abstract: Our experiments have shown that the joint incubation of thymocytes and syngeneic macrophages in vitro for 60 minutes is accompanied by a certain increase in the helper activity of thymocytes. The presence of polyacrylic acid or the copolymer of acrylic acid and N-vinyl-pyrrolidone, containing 56 mol% of acrylic acid, in this system ensures a considerable increase in the helper activity of thymocytes, incubated jointly with marrow cells and sheep red blood cells and then transferred into a cell culture in vivo.
