Bone marrow scintigraphy is a technology which is used in bone marrow mononuclear phagocytes may swallow colloidal imaging agent which is injected by intravenous, and the red bone marrow hematopoietic cells are consistent with mononuclear phagocytes. So it can indirectly observe the red bone marrow distribution. This technology can overcome disadvantage of the traditional biopsy which can only be partially drawn and can provide functional body imaging of bone marrow, simple and noninvasive. So it is used widely in the treatment of disease in the blood disease.
ABSTRACT
Thymus derived CD+4; CD+25 regulatory T cells (Treg) are thought to be specific T cells that play an important role in controlling autoimmunity, preventing transplant rejection, restraining anti-infectious immune response, suppressing allogeneic immune respons. More recently, these cells are reported to have the ability of suppressing antitumor immune response. Foxp3 are the most specific protein of Treg. In this review, we will discuss the expression of CD+4 CD+25 Treg in patients with hematological malignancies and its implication for immunotherapy.
ABSTRACT
Objectives To investigate the ratios of peripheral blood CD4+CD8+ and CD4+CD25+ regulative T cells, and explore the association with hepatic damnification and anti-AMA-M2 antibodies.Methods The percentage of CD4+CD8+T cells and CD4+CD25+T cells in peripheral blood from patients with primary biliary cirrhosis(PBC) (n=27)、26 patients with other hepatic desease、30 normal individuals were measured by flowcytometry.Results Patients with PBC had statistically higher levels of CD4+CD25+T cells than the patients with other hepatic disease (P
ABSTRACT
Objective To evaluate characteristics of hematopoietic and immunologic reconstitution in mixed cord blood transplantation. Methods Single, 2 human HLA-haploidentical or HLA-mismatched cord blood units were transplanted into sublethally irradiated severe combined immunodeficiency (SCID) mice, respectively. The characteristics of engraftment, multilineage hematopoiesis and immunologic reconstitution among the three guoups were compared. Results Single or 2 cord blood units could engraft SCID mice and reconstitute human hematopoiesis and immunologic functions. No significant differences in engrafting rate were observed. Cord blood cells were apt to differentiate into NK cells and B lymphocytes. One or 2 cord blood units could be implanted in SCID mice simultaneously as shown by HLA-DQB1 gene detection. The cord blood containing more hematopoietic progenitor cells and higher colony forming potentiality was apt to engraft. Moreover, in less HLA disparity group, 2 cord blood units were prone to engraft simultaneously. Conclusions Co-transplantation of two cord blood units can reconstitute hematopoietic and immunologic functions in SCID mice. However, imbalance in multilineage differentiation existed.
