The effects of 17β-estradiol (E2) on sympathetic activity were examined in conscious unrestrained ovariectomized rats, instrumented under methohexital anesthesia to record mean arterial pressure (MABP), heart rate (HR), renal nerve activity (RNA), a

The greater pressor response to vasopressin in male than in nonestrous female rats results from a greater increase in total peripheral resistance in males. The present study was performed to identify the vascular beds that contribute to this differen

The present study was carried out to investigate whether prostaglandins (PG) are involved in the mechanism that contributes to the sex difference in the antidiuretic and pressor actions of vasopressin. The experiments were performed in conscious male

We have examined whether the cardiovascular effects of 7-nitroindazole, a reportedly selective inhibitor of neuronal nitric oxide (NO) synthase, are induced without inhibition of endothelial NO synthase. A significant increase in mean arterial blood

Increased plasma osmolality results in increased central as well as peripheral release of vasopressin. Experiments were carried out to determine whether, in this circumstance, vasopressin can act centrally to modulate its peripheral release. Prior to

Vasopressin, a nonapeptide, is synthesized in magnocellular neurons of the paraventricular and supraoptic nuclei. Its release is stimulated by increased osmohiity, sensed by osmoreceptors in the Iamina terminalis, and by reductions in blood volume an

Neuropeptide Y (NPY) and norepinephrine are co-localized in the noradrenergic projection from the A1 nucleus of the medulla to the vasopressinergic magnocellular neurons of the supraoptic and paraventricular nuclei. Because this pathway is involved i

It has been demonstrated that the neurohypophysial hormones can be released intrahypothalamically by the paraventricular (PVN) and supraoptic nuclei. The present experiments were undertaken to determine whether a physiological stimulus for vasopressi

Experiments were carried out, using the technique of in vivo microdialysis in conscious rats, to determine whether hemorrhage, a potent stimulus for the release of vasopressin from the posterior pituitary into the circulation, would also result in a

A possible gender difference in the antidiuretic activity of vasopressin was studied in male and female Sprague-Dawley rats. Infusion of vasopressin (3-100 pg.kg-1.min) into conscious, chronically instrumented water-loaded rats resulted in a dose-dep
