Aims: The interplay between natriuretic dopamine and antinatriuretic angiotensin II represents an important mechanism for the regulation of renal sodium and water excretion. Monoamine oxidase is the main metabolizing pathway for dopamine in the renal

Aims: Acetylcholine (ACh) is known to reduce the contractility of the heart by acting on myocardial muscarinic M2 receptors. ACh induces also an endothelial-dependent vasodilatation by causing the release of nitric oxide (NO), prostacyclin and endoth

Renal vascular resistance is increased in essential hypertension, as in genetic models of hypertension. Here we review the evidence that this is at least in part due to structural changes in the afferent arterioles. Rat studies show that the renal af

Aim: Hepatic xenotransplantation from guinea-pig to rat has not been established. This failure is partly ascribed to differences in hepatic vascular characteristics between two species. However, the differences in hepatic vascular resistance distribu

The factors involved in maintenance and reversal of mean arterial blood pressure (MAP) in the chronic two-kidney one-clip hypertensive rat (2K1C-RHR) are still debated. The reduction in MAP after reversal of 2K1C hypertension has been ascribed either

The vasoconstrictor effects of noradrenaline were studied in spontaneously hypertensive rats (SHR) compared with Wistar Kyoto rats (WKY), and in Wistar rats with regional hypotension (WH) compared to control Wistar rats (WC). The abdominal aorta was

The importance of nitric oxide in regulating basal arterial blood flow has been examined in several different vascular beds by intra-arterial infusion of inhibitors of nitric oxide synthesis, but not in the arterial vascular bed of the liver. In the

We investigated the effects of hydralazine on renal sympathetic nerve activity in anaesthetized heart failure rats. Sham-operated rats (group 1) received 0.5 mg kg -1 of hydralazine as bolus and were then infused with 0.3-0.5 mg kg -1 h -1 for 3 h in

The purpose of this study was to evaluate the effects of short-term sympathetic inhibition with clonidine on blood pressure and renal responses to central hypervolaemia induced by thermoneutral head-out water immersion. Eleven healthy subjects were r

To elucidate the role of adenosine in coronary vasoregulation, we studied the effects of adenosine antagonism (by theophylline) on coronary blood flow at different levels of adenosine formation (stimulated by hypoxia and exercise). Six healthy subjec
