The cellular sites of formation of gammaglobulin in lymphatic tissues of man and in a representative human lymphoid infiltrate have been studied by fluorescent antibody technique. The findings indicate that gamma-globulin is formed in the germinal centers of lymphatic nodules and in the cytoplasm of mature and immature plasma cells of two types-those with and those without Russell bodies. The g...
BACKGROUND Antithymocyte globulin or human Jurkat T-cell-line-derived antilymphocyte globulin is used in allogeneic stem cell transplantation to induce in vivo T-cell depletion to facilitate engraftment and lower graft-versus-host disease. In vitro studies suggest that antithymocyte globulin, besides causing T-cell depletion, has strong anti-myeloma activity. DESIGN AND METHODS We evaluated t...
Studies on antibody formation "in vitro" have supplied information concerning the site of antibody production (1-5), the rates of antibody synthesis per unit weight of tissue (6-7) and the percentage of active cells in lymphoid tissue during the primary and secondary antibody response (8-9). In vitro experiments have also been used in attempts to elucidate the mechanism of induction of antibody...
Previous experiments (l-3) have shown that following hypophysectomy the serum globulin concentration of dogs and rats increases and at the same time the serum albumin level falls. In the above studies serum albumins and globulins were separated by salt fractionation (4). With the aim of checking our earlier results and of obtaining more detailed information regarding the changes in serum protei...
The colloid or protein osmotic pressure (Pi) is a function of protein molarity (linear) and of Donnan and other effects. Albumin is the major osmotic protein, but also globulins influence Pi. Equations based on concentrations of albumin and nonalbumin (globulin concentration + fibrinogen concentration) protein approximate Pi better than albumin alone. Globulins have a wide range of molecular we...
ONSIDERABLE TIME AND EFFORT has been devoted to the problem of fractionating serum protein simply, reliably, and rapidly, and at the same time in conformity with the free electrophoretic separation into albumin and a-, fi-, and 7-globulins. Much progress has been made, but discrepancies remain, especially in connection with aand -gIobulins. A few years ago Wolfson, Cohn, et at. (1) devised a re...
The effect of highly purified rheumatoid factor on the precipitin reactions of various antigen-antibody systems was determined. The amount of nitrogen precipitated was increased over a broad range when the factor was added to ovalbumin, human albumin, or human gamma globulin, and the corresponding rabbit antibodies. In the zone of antigen excess, soluble antigen-antibody complexes were precipit...
It has been shown (Holmes, Stanier, Semambo and Jones, 1951) that the concentration of y-globulin in the serum of apparently healthy adult Africans is considerably higher than that of Europeans. It is also known (Longsworth, Curtis and Pembroke, 1945) that, in white infants, the level of y-globulin of the serum of umbilical cord blood is higher than that of the maternal blood taken on the day o...
OBJECTIVE To investigate the value of serum globulin levels before treatment in predicting the prognosis of patients with nasopharyngeal carcinoma (NPC). METHODS A total of 127 patients with non-disseminated NPC were recruited between January, 2009 and December, 2013 at Nanfang Hospital. The pretreatment serum globulin levels were analyzed with the receiver-operating characteristic (ROC) curv...
Refractory cytopenia of childhood is the most common subtype of myelodysplastic syndrome in children. In this study, we compared the outcome of immunosuppressive therapy using horse antithymocyte globulin (n=46) with that using rabbit antithymocyte globulin (n=49) in 95 patients with refractory cytopenia of childhood and hypocellular bone marrow. The response rate at 6 months was 74% for horse ...
