title: Surface staining of small intestinal biopsies.
abstract: Small intestinal biopsies are most often by routine examined under a stereo-microscope, prior to embedding for histological examination. This is done in order to get a view of the appearance of the mucosal pattern, especially villus configuration. The distinctness of the surface pattern however, is improved considerably if the biopsies are stained with Alcian Green and/or PAS before they are examined. In the present paper a detailed description is given of staining of small intestinal biopsies as whole mounts. The difference between the unstained and the stained biopsies is illustrated by a few examples.
