Influence of renal sympathetic nerve stimulation on renal function in the primate.

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.

Renal actions of neuropeptide Y in the primate.

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. However, little is known about the physiological effects of NPY on the kidney in the human.

[125I]SCH 23982: the ligand of choice for identifying the D-1 dopamine receptor.

[125I]SCH 23982, [125I]8-iodo-2,3,4,5-tetrahydro-3-methyl-5-phenyl-1H-3-benzazepine-7-ol, binds reversibly and with high affinity (Kd = 0.7 +/- 0.05 nM) to specific binding sites (maximum binding = 108 +/- 3.

Dopamine receptor agonist activity of some 5-(2-aminoethyl)carbostyril derivatives.

The potency of beta-adrenoreceptor agonists, e.g., isoproterenol, is strikingly increased by substitution of the meta catecholic hydroxyl group with the NH group of a carbostyril system.

Orally active and potent inhibitors of gamma-aminobutyric acid uptake.

3-Pyrrolidineacetic acid (1a), certain piperidinecarboxylic acids--i.e., 3-piperidinecarboxylic acid (2a), 1,2,5,6-tetrahydro-3-pyridinecarboxylic acid (3a), and cis-4-hydroxy-3-piperidinecarboxylic acid (4a)--cis-3-aminocyclohexanecarboxylic acid (5a, cis-3-ACHC), and gamma-aminobutyric acid (6a, GABA) itself are among the most potent inhibitors of [3H]GABA uptake by neurons and glia in vitro.
