T-CELL REST POPULATION OF DIFFUSE LYMPHOMAS OF B-CELL TYPE

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

Abstract

By using Alpha-Naphthyl-Acetate-Esterase-Staining (ANAE), we investigated the rest population of T-cell in diffue lymphomas of B-cell origin, which consist of 15 cases of CLL, 30 cases of IC, 5 cases of PRL, 17 cases of CC and 16 cases of IML. The percentages of Droplet cells changed from case to case, but the highest percentage was seen in IML (19.90 %), on the contrary, the lowest CLL (7.80%) . It may be suggested that even diffuse lympho-mas of B-cell type have relatively many T-cell Rest Populations, considering there is seen the fact of absolute number increasing of Tγ-cells in B-cell neoplasms and in addition, some parts of T-cell are ANAE negative.
