[Total protein and immunoglobulin levels in the body fluids of healthy and Rh-incompatible pregnant women].

The content of total protein and immunoglobulins in blood serum, saliva and breast-milk of healthy pregnant women and of pregnant women with anti-D-antibodies has been determined by the biuret-method and radial immunodiffusion. The values of immunoglobulins in every body fluid are typical and they respond to pregnancy. The investigations vindicate theory of local antibody synthesis. The differences of immunoglobulins from healthy pregnant women and from patients with antibodies were discussed.
