JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 731 OP 735 DO 10.1136/jcp.39.7.731 VO 39 IS 7 A1 A J Freemont A1 C Rutley YR 1986 UL http://jcp.bmj.com/content/39/7/731.abstract AB Synovium from 142 patients with 12 different arthropathies was examined for the distribution of alpha, delta, gamma, and mu immunoglobulin heavy chains. A high proportion of plasma cells in the superficial subintima in all diseases reacted for alpha heavy chains. Only in rheumatoid disease did the synovium contain more than 10% of plasma cells reacting for mu heavy chains.
