TLDR
The chemical nature of neurosecretory material of the brain and lateral nerve cords in the heteronemertean Cerebratulus marginatus has been examined by a variety of histochemical methods and it appears that the secretions of the cell types are characterized by a content of cystine and tryptophan or other 3-indolyl derivatives.About:

Ultrastructure and histochemistry of neurosecretory cells and neurohaemal areas in the pond snail Lymnaea stagnalis (L.)
TL;DR: Seven types have been distinguished within the class of Gomori-positive cells on the basis of different staining reactions with the alcian blue/alcian yellow technique, which revealed that each of the histochemically distinguished secretory substances consists of elementary granules which differ in size and appearance from each other and from the neurosecretory elementarygranules which have been described in the cerebral ganglia and in the lateral lobes.

The evolution and comparative physiology of terrestrial and freshwater nemerteans
Janet Moore,Ray Gibson +1 more
TL;DR: The relationships between the known terrestrial and semi‐terrestrial nemerteans, comprising seven genera and 15 species, are defined and their geographic distribution is discussed.

Cellular Dynamics in Invertebrate Neurosecretory Systems
TL;DR: This chapter discusses the cellular dynamics in invertebrate neurosecretory systems and the techniques of electron microscope autoradiography and chromatographic and electrophoretic microtechniques have the potential to provide valuable information on granule processing and transport.

The nervous systems of Pilidiophora (Nemertea)
TL;DR: Although in H. dubia some characters of the nervous system show the plesiomorphic state, the morphology of the cerebral organ provides an apomorphic character for a taxon Pilidiophora, which is now supported as the sister group to heteronemerteans.
Journal ArticleDOI
Histochemical observations on the localization of some enzymes associated with digestion in four species of Brazilian nemerteans.
TL;DR: The processes of digestion have been investigated histochemically for several nemertean species and results so far obtained suggest that although the fundamental digestive sequence is essentially similar for all the species, differences in details can be related either to their systematic position or mode of life.

TL;DR: A new histochemical test for protein and peptide, based on the liberation aldehyde groups by ninhydrin or alloxan oxidation, and subsequent demonstration of aldealdehyde by reduced fuchsin, has been described and proved to be preferable in many respects.
