Cytochemical characteristics of the neurosecretory cells of Ceylonocotyle scoliocoelium (Trematoda: Digenea).
Two types of neurosecretory cells (NSC), large alpha cells and small beta cells were detected on the basis of their size and characteristics as shown by aldehyde fuchsin and chrome haematoxylin-phloxin staining. A histochemical survey of the neurosecretory material indicates that it is a glycoprotein. Phosphatases and esterases present in NSC probably help in the transfer of metabolites and their hydrolysis and in the control of secretory material produced in a NSC, while SDH provides the necessary energy for the synthetic activity of the latter. The role of neurosecretion in governing the reproduction of this parasite is discussed.
