[Immune function and abdominal surgery in blood stasis syndrome in patients with gastrointestinal diseases].

ABSTRACT

52 Patients with Blood Stasis Syndrome (BSS) in abdominal surgical diseases were divided into 3 types according to their symptoms, signs and natures of diseases. Peripheral blood T lymphocyte subsets of these BSS patients and 12 healthy persons were studied with Flow Cytometry and monoclonal antibodies. The immunoglobulins and complements of these cases were also studied. There were no difference in T cell subsets, immunoglobulins and complements between Qizhi-BSS group and normal control. The Shire-BSS group showed that CD8 cell, IgG, IgM, and C1, C3c were increased. These results showed that the immune response increased in this type of BSS patients. In the Qixu-BSS group, the CD3 was nearly normal, and the CD4+, CD4+/CD8+ ratio, and CD16+ were statistically decreased. However, the CD8+ cells markedly increased, the IgG, IgM and IgD were also lowered significantly in this type. The marked morphologic abnormal changes in ultrastructures of T lymphocyte were found in 6 patients with Qixu-BSS group. These results showed that the Qixu type of Blood Stasis Syndrome patients were in the immuno-suppressive status.
