Abstract
Thirty-nine patients with Crohn's disease and 17 normal people were tested for hypersensitivity to sarcoid and normal spleen suspensions using the leucocyte migration test. In 26% of the Crohn's cases migration was inhibited, whereas inhibition was not significant in the control group. Migration inhibition did not appear to be related to duration or activity of the disease. Sixty-two percent of the Crohn's patients showed migration stimulation against normal spleen, a phenomenon that did not occur in the control group.
