The effect of histamine on the induction of experimental autoimmune hemolytic anemia on OF1, BALB/c and SJL mice.

Erythrocyte autoantibodies can be elicited in mice by injection of rat red blood cells (RBC) which are cross-reactive with mouse RBC. In this report, we show that histamine injected in vivo delayed the production of autoantibodies among BALB/c and OF1 mice. In contrast, the induction of autoantibodies in SJL mice was not affected by histamine.

Immunomodulation induced by immunoglobulins. I. Action of placental immunoglobulin on in vitro spontaneous synthesis of IgE in man.

The IgE contents of various therapeutic immunoglobulin (Ig) preparations of placental or plasmatic origin were measured. Their effects on spontaneous IgE synthesis by lymphocytes from healthy and atopic subjects were also studied. Whatever their origin, Igs contained IgE in varying amounts, depending on the batch.

[Evaluation of erythrocyte survival by the determination of glycosylated hemoglobin. Clinical value].

In normoglycaemic subjects the haemoglobin glycosylation rate primarily depends on duration of erythrocyte life. Measurements of glycosylated haemoglobin therefore can be used to evaluate erythrocyte life. Indeed, glycosylated haemoglobin is significantly reduced (p less than 0.

[Hemolytic disease of newborn infants caused by anti-Diego antibodies].

A native Cambodian woman delivered a third full-term female baby who had a strongly positive direct antiglobulin test. During the pregnancy and after the delivery, the woman had a negative irregular antibody screening test using standard red blood cell panels, but the indirect antiglobulin test between the mother's serum and the father's red blood cells was strongly positive. The antibody could be eluted from the baby's red blood cells and its was identified as an anti-Dia (Diegoa).
