We measured changes in plasma renin activity (PRA) and used angiotensin-converting enzyme blockade with captopril to evaluate the role of the renin-angiotensin system during hemorrhage and after opioid receptor blockade in conscious rabbits. The incr

We tested the hypothesis that the pressor effect of naloxone during acute hemorrhagic hypotension is mediated in part at peripheral sites. Experiments were performed in conscious, chronically prepared rabbits. First, we compared the hemodynamic respo

Serotonin (5-HT) receptors in the myenteric plexus mediate contractility in vitro and may regulate gastric emptying in vivo. This report examines the pharmacology of three benzamides, ML-1035 (4-amino-5-chloro-2-[2-(methylsulfinyl)-ethoxy]-N-[2- (die

We tested the hypothesis that enkephalins or some other compound(s) released by the adrenal medulla during hemorrhage were responsible for the resultant hypotension. We compared the hemodynamic and plasma catecholamine responses to hemorrhage and sub

The hemodynamic and plasma catecholamine response to hypotensive hemorrhage and subsequent opioid receptor blockade with naloxone were evaluated before and after complete sinoaortic denervation (SAD). This study was done to test the general hypothesi

The isolated perfused guinea-pig heart prelabeled with (-)-[7-3H]-norepinephrine was used to examine the effects of increasing concentrations of ouabain on the sympathetic nerve stimulation-evoked release of endogenous norepinephrine and [3H]norepine

The isolated perfusion cat spleen prelabeled with [3H]norepinephrine was used to study the effects of morphine and Met-enkephalin on the exocytotic release of norepinephrine from sympathetic adrenergic neurons after nerve stimulation. The overflow of

The hemodynamic effects of i.a. [met]enkephalin were studied in the hindquarter vasculature of chronically prepared, conscious rabbits. A new method allowed i.a. injection while simultaneously measuring blood pressure and blood flow to this vascular

The involvement of the sympathetic nervous system in the cardiovascular response to hemorrhage and subsequent opiate receptor blockade was studied in conscious rabbits. Plasma catecholamines were measured by high-pressure liquid chromatography to ind
