RT Journal Article SR Electronic T1 Lamina propria mast cells in biopsies from children with Crohn's disease. JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 279 OP 283 DO 10.1136/jcp.39.3.279 VO 39 IS 3 A1 Sanderson, I R A1 Leung, K B A1 Pearce, F L A1 Walker-Smith, J A YR 1986 UL http://jcp.bmj.com/content/39/3/279.abstract AB Biopsies from actively inflamed areas of terminal ileum or colon in children with Crohn's disease were examined both for lamina propria mast cell density and histamine content. These were reduced in comparison with those of normal controls. The release of histamine from biopsies of inflamed tissue did not differ greatly from that of normal tissue, either spontaneously or after receiving an antihuman IgE challenge.
