title: Caudal neurosecretory system of a fresh water percid teleost, Colisa fasciatus (Bl. and Schn.): a histocytochemical study.
abstract: Histocytochemical aspects of the caudal neurosecretory system of C. fasciatus have been studied. Caudal neurosecretion is proteinaceous and contains free-NH2 groups. It does not contain-SH/-SS groups and carbohydrates. Dahlgren cells show positive reaction for RNA, and Nissl bodies. Small amount of lipid may be associated with the secretion. Neurosecretory axons are nonmyelinated.
