Summary Histochemical studies of the nervous system of Fasciola gigantica and Fasciola hepatica were undertaken. Neurosecretory cells were detected by Gomori's aldehydefuchsin, Bargmann's chrome hematoxylin-phloxin, Mallory's triple stain, periodic acid-Schiff, Heidenhain's Azan and alcian blue after potassium permanganate oxidation. Two types of neurosecretory cells were recognized and designated as “A” and “B”. Type “A” cells occurred in small numbers in the brain and subesophageal mass and type “B” cells were ubiquitous in distribution. The reactions of these cells to the standard stains for neurosecretory substance generally, were less intense than the neurosecretory cells of other animals such as crustaceans and insects. The structure, organisation, distribution and cytochemistry of neurosecretory cells in Fasciola gigantica and Fasciola hepatica is discussed.
