title: Alcian blue method for the museum display of squamous metaplasia in the larynx.
abstract: The Alcian blue method is described as an alternative to the use of pyronin for the immediate post-mortem demonstration of squamous in the larynx. Alcian blue-stained specimens can be stored for prolonged periods in 4 per cent formaldehyde in normal saline without loss of contrast and used as wet specimens for teaching purposes. Alcian blue-stained larynges showing squamous metaplasia can be permanently mounted for museum display in either Kaiserling's or Wentworth's fluids.
