[Local and general humoral immunity in peptic ulcer patients]

The content of immunoglobulins (IgM, G, A) and secretory IgA in the saliva, gastric juice and blood serum was studied in 83 patients with duodenal ulcer. The secretory IgA in the saliva, gastric juice and blood serum was found to be reduced in patients with a protracted course of ulcer disease. Healing of ulcers was not accompanied by normalization of indices of general and local immunity in the gastric juice and saliva.
