[Comparative study on in vitro lymphocytotoxicity and mitogenicity of different antilymphocyte globulin (ALG) preparations]. 1989

Y Kawano, and Y Takaue, and T Watanabe, and T Ninomiya, and Y Kuroda, and C Nissen, and A Gratwohl, and B Speck

The lymphocytotoxicity and mitogenicity between six different ALG preparations on the clinical use world wide were compared. No significant difference in the lympholytic activity was observed between preparations and 100% cell lysis was achieved at a concentration of 50 micrograms/ml in the presence of complement. On the other hand, four preparations now in use in European countries and USA showed variable mitogenic activities on lymphocytes in the absence of complement, whereas two ALGs used in Japan did not. As the stimulatory effects of ALG on lymphocytes may contribute to the clinical outcome in the treatment of severe aplastic anemia (Kawano et al, 1988), these date can explain the poor clinical results of ALG therapy with those two preparations in Japan. Careful measures should be paid in the construction of treatment protocol and selection of ALG preparations to yield the best results.

UI MeSH Term Description Entries
D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION. Blast Transformation,Blastogenesis,Lymphoblast Transformation,Lymphocyte Stimulation,Lymphocyte Transformation,Transformation, Blast,Transformation, Lymphoblast,Transformation, Lymphocyte,Activation, Lymphocyte,Stimulation, Lymphocyte
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell
D003602 Cytotoxicity, Immunologic The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitized T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement.
