Abstract
The numbers of immunoglobulin-containing cells in the mucosae of the small intestine and rectum were counted by a direct immunofluorescence technique in biopsy specimens from children. Immunoglobulins in the intestinal juice of the same patients were quantified by electroimmunodiffusion. In all biopsy specimens IgA-containing cells predominated. These cells were more numerous in the specimens from children over 2 years of age than in those of younger ones. The cells seemed to be fairly evenly distributed along the intestinal tract. The number of IgM-containing cells did not change with age in the group studied.
