Effects of acetylsalicylic acid on lymphocyte subpopulations in peripheral blood.

Abstract

The in vitro and in vivo effects of therapeutical doses of acetylsalicylic acid on lymphocyte subpopulations in peripheral blood were investigated with the following results: Acetylsalicylic acid caused both in vitro and in vivo a reduction of complement receptor bearing lymphocytes and of lymphocytes identified with fluorescent rabbit antibody to human Ig (polyvalent) and to human IgG. Sheep red blood cell receptor bearing lymphocytes, and lymphocytes identified with antibody to human IgM and IgD were unaffected by acetylsalicylic acid.
