[Inhibition of leukocyte migration after concanavalin A and phytohemagglutinin in patients with ulcers].
An attempt of the assessment of T-cells function in patients with gastric or duodenal ulcer has been undertaken. The studies involved 60 patients with gastric or duodenal ulcers and 47 individuals of the control group. Lymphocyte reactivity to different concentrations of concanavalin A and phytohemagglutinin has been assessed with leukocyte migration inhibition test. Lymphocyte T function has been examined also in patients with gastric or duodenal ulcers in reference to the theophylline-dependent and theophylline-sensitive subpopulation of T-cells. Leukocyte migration index values after phytohemagglutinin and concanavalin A did not differ significantly in patients with gastric or duodenal ulcers and theophylline-sensitive T-cells. Differences have been noted in the migration inhibition deficits. This phenomenon has been least frequent in case of phytohemagglutinin in the control group (5.8%) and most frequent in patients with gastric ulcer (62%). Percentage of patients responding to higher concanavalin A concentration (40 micrograms/ml) with leukocyte migration inhibition has been the highest in patients with duodenal ulcer. This index value has been significantly lower (p < 0.05) only in patients with duodenal ulcer and increased number of theophylline-dependent lymphocytes T. Increased reactivity of T-cells to higher concanavalin A concentration in patients with duodenal ulcer with theophylline-dependent T-cells in peripheral blood probably indicates increased the suppressor lymphocytes activity.
