title: Immunohistochemical identification of lysozyme in pseudopyloric gland metaplasia in Crohn's disease.
abstract: Using an immunoperoxidase technique lysozyme (LZM) was identified in the ileum of patients with Crohn's disease in inflammatory cells of the lamina propria, in Paneth cells and in pseudopyloric gland metaplasia. These observations demonstrate a further analogy of pseudopyloric gland metaplasia with true pyloric glands, and may offer an additional explanation for the raised concentration of serum-LZM in patients with Crohn's disease.
