To determine the effect of diabetes mellitus on the levels of substance P (SP), calcitonin gene-related peptide (CGRP), and vasoactive intestinal polypeptide (VIP) in the rat cornea and iris.Corneas and irides from control and diabetic rats were proc

The sensory innervation of the rat kidney and ureter was investigated in wholemount preparations and sectioned materials by labeling the afferent nerve fibers with wheat germ agglutinin-horseradish peroxidase (WGA-HRP) transported anterogradely from

We characterized the influence of high pressure and low pressure intravascular receptors on renal nerve activity in the pentobarbital sodium-anesthetized nonhuman primate Macaca fascicularis. Epinephrine-induced increases in arterial pressure were us

To investigate the role of endogenous prostaglandins in renin release stimulated via adrenergic pathways, isoproterenol, norepinephrine (NE) and NE in the presence of phentolamine (PTA) were infused into conscious sodium-replete rats and dogs. Isopro

Neuropeptide Y (NPY) is a potent vasoconstrictor peptide contained in sympathetic nerve terminals and is co-released with norepinephrine. Previous studies in the rat have suggested that NPY influences renal sodium reabsorption and renin release. Howe

Prostaglandins have been implicated as important regulators of vascular resistance during high-renin states, and they act as potent stimuli for renin release. This study examines the effects of prostacyclin (PGI2) in conscious sodium-replete and -dep

Experiments were performed in chloralose-anesthetized cats to characterize intravascular mechanoreceptro input to renal nerve activity in the intact and vagotomized sinoaortic-denervated states. High-pressure intravascular mechanoreceptors were stimu

Experiments were done in the nonhuman primate Macaca fascicularis to determine the extent to which low-pressure receptors modulate renal nerve activity (RNA). Left atrial pressure (LAP) was increased either by inflating a balloon in the left atrium o

In anesthetized Macaca fascicularis monkeys renal sympathetic nerves were stimulated electrically while changes in renal function were measured. The range of stimulation frequencies was 0.25-4.0 Hz. In the primate the stimulation threshold for change
