Does chronic alpha1-adrenergic blockade improve hypertension and renal injury in L-NAME and low-renin L-NAME-DOCA hypertensive rats?
Alpha1-adrenergic tone plays an important role in the increased BP and renal injury of L-NAME hypertension. Our results also indicate that when PRA is suppressed by DOCA in L-NAME hypertension, the increased BP and renal injury are largely dependent on the alpha1-adrenergic tone.
The particular etiopathogeny of these lesions is been discussed. The treatment, medical and of rehabilitation could achieve a partial recovery. In the event of surgery, an access to the lesion through a cordotomy and not directly by removal with microcissors is advised.
