title: [Effect of an operation on the immunoreactivity indices, their postoperative dynamics and the effect of 3-HAA-antigen on these indices in patients with gastrointestinal tumors].
abstract: The following parameters were studied in cases of gastrointestinal tumors: 3-hydroxyanthranilic acid (3-HAA)-antigen in blood serum; antibodies to 3-HAA-antigen; immunoglobulins G, A and M (after Manchini); 3-HAA-antigen effect on blastogenic reaction of lymphocytes; 3-HAA-antigen effect on leucocyte migration; blood serum effect on cells producing antibodies to ram erythrocytes, and levels of T-lymphocytes and their subpopulations. The studies were conducted before operation, 4-6, 7 and more months after operation. Tumor removal as well as tumor recurrences and metastases were shown to have an effect on the first 4 parameters. 3-HAA-antigen stimulated the formation of specific antibodies, suppressed blastogenic reaction of lymphocytes but failed to affect leucocyte migration significantly.
