This report seeks to extend the existing information on the relationship of regulatory neuropeptides to neuroendocrine and pituitary function through a longitudinal study of the distribution of FMRF-amide, galanin (GAL), and neurotensin (NT) in the brain and pituitary gland of three species of Xiphophorus from birth to sexual maturity. In the pituitary(More)
Immunoreactive (ir) lamprey (l), mammalian (m), chicken II (chII), and salmon (s) gonadotropin-releasing hormone (GnRH) and ir-coho salmon beta-gonadotropins I and II (GTH I and GTH II) have been localized in the brain and pituitary gland of Xiphophorus maculatus, the platyfish, at various stages of development from birth to sexual maturity. Ir-GTH I was(More)
The androgen receptor (AR) was localized immunohistochemically after different hormonal treatments in the ventral prostate, coagulating gland, seminal vesicle and epididymis of the adult rat. In the untreated controls AR-immunoreactivity was confined to the cell nuclei. One week after castration or treatment with the gonadotropin-releasing hormone(More)
Immunoreactivity to gonadotropin-releasing hormone (GnRH) and gonadotropic hormone (GTH) was studied at the light-microscopical level in the brain and pituitary of rainbow trout at different stages of the first reproductive cycle using antisera against synthetic mammalian GnRH and salmon GTH. GnRH perikarya were localized exclusively in the preoptic(More)
The light microscopic analysis of serial sections of the subcommissural organ (SCO) of the rainbow trout (Salmo gairdneri) shows that the form of the groove-like (in cross section) organ varies over its total length. Its rostral origin is a tunnel-like structure anterior to the orifice of the hollow pineal stalk. The SCO forms the dorsal wall of the brain.(More)
