title: [Lymphocyte changes in patients with Graves's disease accompanied by hematocytopenia].
abstract: The aim of study was to investigate the lymphocyte changes in peripheral blood of patients with Graves's disease accompanied by hematocytopenia and to explore its pathogenesis. The quantity and ratio of Th(2), Th(1), CD5(+) B, Bcl-2 level in 24 Graves's disease patients with hematocytopenia were detected by FACS, and 18 adults were selected as normal controls. The results indicated that the percentages of Th(1), Th(2), ratio of Th(2)/Th(1), CD5(+) B, Bcl-2 level in peripheral blood of the patients were (0.81 +/- 0.45)%, (6.83 +/- 3.02)%, (20.55 +/- 6.15)%, (20.89 +/- 1.62)%, (80.25 +/- 15.56)%, respectively, and were higher than those of normal controls [(0.39 +/- 0.24)% (P<0.05), (0.28 +/- 0.15)% (P<0.01), (0.52 +/- 0.12)% (P<0.01), (7.89 +/- 0.38)% (P<0.05), (36.49 +/- 6.79)% (P<0.05)]. It is concluded that the pathogenesis of Graves's disease with hematocytopenia may be related to unbalance of Th(1)/Th(2), increase of Th(2) inducing over-expression of CD5(+) B and Bcl-2 on B cell.
