We assessed whether acute intra-arterial infusion of exogenous ghrelin can improve endothelial dysfunction by restoring nitric oxide (NO) availability in the forearm microcirculation of essential hypertensive patients. The effect of ghrelin on endothelial dysfunction (pressurized myograph), vascular oxidative stress generation (fluorescent dihydroethidium), and phosphorylation of p47phox (western blot), an index of NAD(P)H oxidase activation, in isolated small arteries taken from essential hypertensive patients (subcutaneous biopsy) were also investigated.

Abstract
We assessed whether acute intra-arterial infusion of exogenous ghrelin can improve endothelial dysfunction by restoring nitric oxide (NO) availability in the forearm microcirculation of essential hypertensive patients. The effect of ghrelin on endothelial dysfunction (pressurized myograph), vascular oxidative stress generation (fluorescent dihydroethidium), and phosphorylation of p47phox (western blot), an index of NAD(P)H oxidase activation, in isolated small arteries taken from essential hypertensive patients (subcutaneous biopsy) were also investigated.File in questo prodotto:
