[Salivary immunoglobulins G, A and M in liver cirrhosis].

Mixed saliva of the patient with cirrhosis of the liver contains often large quantities of immune globulins. IgA and M transport is facilitated, but whereas IgA globulins are present in all cases, the IgM appear in the saliva only where plasma concentration is greater than 200 mg %. Owing to a simple passive diffusion mechanism, the IgG reach high saliva levels in all subjects studied.
