A number of diseases in man are associated with markedly increased gamma globulin levels in the serum and an even greater increase in total gamma globulin pool. The most striking of these is multiple myeloma, but elevations are also seen in cirrhosis of the liver, certain of the collagen diseases such as lupus erythematosus and rheumatoid arthritis, and a variety of chronic infectious processes...

Both synthetic and catabolic processes determine the serum gamma-globulin level. The rate of gamma-globulin synthesis appears to be the primary factor determining the amount of serum gamma-globulin. Increase of gamma-globulin synthesis (as may occur following immunization or development of plasma cell tumor) elevates the serum gamma-globulin level. This, in turn, accelerates the fractional rate...

Immunization of guinea pigs with denatured autologous gamma globulin results in the development of delayed hypersensitivity to some form of gamma globulin. When the autologous gamma globulin is subjected to denaturation with alkaline treatment as employed in this study, guinea pigs regularly develop reactivity to the immunizing material and occasionally to some form of heterologous gamma globul...

1. Gamma globulin metabolism and distribution were studied employing rabbit gamma globulin (RGG)I(131) 24 times in 13 control rabbits. Similar studies were performed before and during the ananmestic response in 4 rabbits previously sensitized with a polyvalent pneumococcal vaccine. 2. During the ananmestic response, gamma-globulin levels increased from 1.0 to 6.0 gm/100 ml, and the gamma-globul...

Electrophoresis of urine to evaluate different urinary proteins has been used in recent years veterinary medicine, as it can be a useful laboratory tool the early detection kidney damage. However, capillary electrophoresis (UCE) not reported healthy cats. In dogs, reference intervals have established and compared with pathological samples these provide an easily interpretable pattern. The elect...

The immunologic response of graft recipients to antilymphocyte globulin has been studied. The clearance from the serum of (125)I-labeled antilymphocyte globulin was studied in 15 graft recipients previously treated with antilymphocyte globulin and in 4 control patients not previously treated with antilymphocyte globulin. The mean serum half-life of antilymphocyte globulin was 7.2 days in contro...

In rabbits hyperimmunized with pneumococcal vaccine high concentrations of gamma globulin are produced. In such rabbits, plasma volume was determined with (131)I-labelled rabbit albumin and red cell volume with (51)-Cr-labelled autologous red cells. It was found that the plasma volume increased with increasing gamma globulin concentration, the highest values observed being about 10 gm. per cent...

Various preparations of gamma-globulin homogeneous in the ultracentrifuge showed a similar content of hexose, hexosamine, fucose, and sialic acid. Subfractionation of Fr. II gamma-globulin by zone electrophoresis revealed multiple components of different mean mobilities but containing similar amounts of carbohydrate. Gamma globulin isolated directly from normal serum by zone electrophoresis sho...

The serological and physicochemical properties of the following three forms of human anti-gamma-globulin factors were compared: (a) rheumatoid factors; (b) Milgrom type anti-gamma-globulin factors; and (c) factors directed against an antigen in human gammaG-globulin that is hidden in the intact molecule and revealed by enzymatic digestion at low pH. The property common to these factors is abili...
