In 13 normotensive subjects on a normal sodium diet, we studied hormonal, blood pressure, and renal vascular changes and dextran sieving profiles induced by infusion of exogenous angiotensin II (Ang II) (5 ng.kg-1.min-1). during baseline conditions and after 5 days of administration of the angiotensin converting enzyme inhibitor cilazapril. Cilazapril induced a renal vasodilative effect without...

BACKGROUND Angiotensin converting enzyme (ACE) inhibition has been shown to prevent neointima formation after vascular injury in rats. However, clinical results evaluating restenosis after angioplasty have been negative. The goal of the present study was to evaluate the influence of the renin-angiotensin system (RAS) status on the effect of ACE inhibition on neointima formation. METHODS AND R...

BACKGROUND Antihypertensive agents differentially influence the plasma adiponectin concentration and the effects of fixed-dose combination regimens remain unclear. The influence of a combination of an angiotensin-converting enzyme inhibitor (ACEI) and a thiazide-type diuretic or an ACEI alone on plasma adiponectin concentrations in patients with essential hypertension was evaluated in the prese...

BACKGROUND The aim of this study was to find out whether angiotensin-converting enzyme (ACE) inhibitors, enalapril and cilazapril, affect the anticonvulsant action of some second-generation antiepileptics, lamotrigine (LTG), topiramate (TPM) and oxcarbazepine (OXC). METHODS The effects of ACE inhibitors on antiepileptic drugs were examined in the mouse model of maximal electroshock. RESULTS...

1. The pharmacokinetic and pharmacodynamic properties of the angiotensin converting enzyme (ACE) inhibitor cilazapril were studied in 30 hypertensive patients with various degrees of renal function. 2. After a single oral dose, apparent cilazaprilat clearance was dependent on renal function being 16.0 +/- 3.0, 11.1 +/- 3.0, 8.7 +/- 3.7 and 6.7 +/- 2.1 l h-1 (means +/- s.d.) in patients with cre...

To elucidate the contribution of the renin-angiontensin system (RAS) to glomerular injury in salt-sensitive hypertension, we investigated the chronic effects of the angiotensin I-converting enzyme inhibitor cilazapril and the angiotensin II type 1-receptor antagonist (AT1a) TCV-116 in Dahl-Iwai rats. Dahl salt-sensitive (S) rats receiving 8% salt diet for 6 wk were simultaneously treated with c...

The Dahl salt-sensitive (DS) rat, a genetic model of salt-induced hypertension in humans, is more likely to develop severe vascular injuries than a rat with spontaneous hypertension. We designed an experiment to scrutinize the effects of renin-angiotensin inhibition on cognitive dysfunction in the aged, normotensive DS with a passive avoidance test. Eighteen months of treatment with a very low ...

INTRODUCTION Ghrelin is a polypeptide hormone secreted mainly by the stomach cells, stimulating food intake and growth hormone release. Decreased plasma ghrelin concentration was found in obese subjects. Clinical and experimental data suggest that ghrelin also exerts a blood pressure lowering property. The influence of antihypertensive medication on plasma ghrelin concentration has not been stu...

BACKGROUND The effect of balloon injury on the arterial signal transduction pathway has not been examined. In vitro studies show that extracellular signal-regulated kinases (ERKs) and c-Jun NH2-terminal kinases (JNKs), belonging to the mitogen-activated protein kinase (MAPK) family, play a critical role in the activation of transcription factor activator protein-1 (AP-1) and cell proliferation ...
