Ovine prolactin has been shown to initiate porphyropsin synthesis in “second metamorphosis” of the eastern red-spotted newt ( Notophthalmus viridescens ). Prolactin activity is demonstrable in both terrestrial juvenile efts and aquatic adults. In

Fishes display a variety of anatomical relationships between brain and pituitary to a degree unique among vertebrates. This group is pivotal for understanding evolution of functions of hypophysiotropic peptides. We review information concerning occur

An immunocytochemical unlabeled antibody enzyme technique has been applied to localize mammalian-like immunoreactive luteinizing hormone-releasing hormone (ir-LH-RH) in central nervous tissue of Pacific lamprey (Entosphenus tridentata; anadromous spa

Testes from 1-day old mice were implanted bilaterally into the inguinal fat pads of young adult mice in order to characterize the initial vascularization of grafts. Implants were permitted to remain in the transplantation site for varying periods of

1. 1. Prolactin, which has sodium-retaining activity in some teleost fishes in fresh water, was examined for similar activity in leopard frogs ( Rana pipiens ) and California newts ( Taricha torosa ). 2. 2. Adenohypophysectomy of R. pipiens and T. to

To assess a possible role of the adenohypophysis in photorefractoriness, photosensitive and photorefractory adult male white-crowned sparrows (Zonotrichia Ieucophrys) were treated with single intravenous injections of 0, 0.5, 5, 20, 35, 50 or 500 ng

The relationship between prolactin-thyroxine antagonism and the metamorphosis of visual pigments in larval amphibians has been investigated using bullfrog (Rana catesbeiana) tadpoles. Although prolactin-thyroxine antagonism is demonstrable by morphol

Hagfish ( Eptatretus stouti ) thyroid tissue co-cultured with pituitary tissue increased thyroxine (T 4 ) concentration in medium relative to thyroids incubated alone. Synthetic thyrotropin releasing hormone and arginine vasotocin failed (a) to augme

1. The distribution of visual pigments among the Amphibia has been reviewed and the relationship between the porphyropsin-rhodopsin visual pigment systems and metamorphosis has been discussed. 2. Retinas of larval California newts (Taricha torosa) an
