1. Efeitos sequenciais do treinamento físico sobre a plasticidade de vias ocitocinérgicas centrais em ratos normotensos e hipertensos. / Sequential effect of aerobic training on the plasticity of central oxytocinergic system in normotensive and hypertensive rats.
Nós investigamos o efeito sequencial do treinamento aerório (T) nas vias ocitocinérgicas (OTérgicas) em áreas centrais autonômicas, utilizando o fator neurotrófico derivado do cérebro (BDNF) como um indicador de plasticidade neuronal. Ratos normotensos (WKY) e espontaneamente hipertensos (SHR) foram submetidos a T ou sedentarismo (S) por 8 semanas. T

2. Reversible fatigue of stimulus-secretion coupling in the rat neurohypophysis.
Single rat neurointermediate lobes were impaled on a stimulating electrode and continuously perifused with oxygenated medium. The secretion of oxytocin and vasopressin into the medium was measured by specific radio-immunoassays. The temporal profile of vasopressin release during a 20 min period of 13 Hz stimulation was compared with that of oxytocin. The res

3. Oxytocin mediates atrial natriuretic peptide release and natriuresis after volume expansion in the rat.
Our previous studies have shown that stimulation of the anterior ventral third ventricular region increases atrial natriuretic peptide (ANP) release, whereas lesions of this structure, the median eminence, or removal of the neural lobe of the pituitary block ANP release induced by blood volume expansion (BVE). These results indicate that participation of the

4. The ACTH cells in the pituitary gland of the nine-spined stickleback, Pungitius pungitius L.
The ACTH cells form a layer 1-8 cells thick, dorsal to the prolactin cells in the rostral pars distalis. They react only mildly with a variety of stains including PAS-lead haematoxylin. Their nuclear diameters vary seasonally in a manner that closely parallels that of the prolactin cells. The relative volumes of the ACTH and prolactin cell zones are remarkab

5. Australian lungfish neurohypophysial hormone genes encode vasotocin and [Phe2]mesotocin precursors homologous to tetrapod-type precursors
In view of the well-established role of neurohypophysial hormones in osmoregulation of terrestrial vertebrates, lungfishes are a key group for study of the molecular and functional evolution of the hypothalamo-neurohypophysial system. Here we report on the primary structure of the precursors encoding vasotocin (VT) and [Phe2]mesotocin ([Phe2]MT) of the Austr
