THE CHANGES OF T-CELL AND PLASMACYTOID LYMPHOCYTE IN PERIPHERAL BLOOD OF LYMPHADENITIS AND IMMUNOBLASTIC LYMPHADENOPATHY

—INVESTIGATION BY ALPHA-NAPHTHYL-ACETATE-ESTERASE STAIN—

Abstract

We investigated here Alpha-Naphthyl-Acetate-Esterase activities of lymphocytes in the peripheral blood of 30 cases of chronic nonspecific lymphadenitis, 10 cases of specific granulomatous lymphadenitis, 8 cases of immunoblastic lymphadenopathy (IBL) and several lymphadenopathies except malignant lymphomas and leukemias. Comparing with chronic nonspecific lymphadenitis, remarkable decrease of ANAE-Droplet positive cell was shown in IBL. Increase of Droplet positive cell was most prominent in specific granulomatuos lymphadenitis. The granular positive cell (plasmacytoid lymphocyte) was shown almost the same value between IBL and specific granulomatuos lymphadenitis, but it may be indicated that increase of plasmacytoid lymphocyte of IBL might suggest a paraneoplastic phenomen differing from the lymphadenitis which reflexes reactive nlasmacvtosis.
