[Use of fondaparinux during hemodialysis in heparin-induced thrombocytopenia. About a new observation].

Several alternative anticoagulation drugs are now available for patients with heparin induced thrombocytopenia type II (HIT II). However, their indication is not yet reaching a consensus. Moreover, some of them have not yet their marketing approval.

Chronic treatment with the angiotensin I converting enzyme inhibitor, perindopril, restores the lower limit of autoregulation of cerebral blood flow in the awake renovascular hypertensive rat.

Chronic hypertension shifts the lower limit of cerebral blood flow autoregulation to a higher pressure level. Although acute administration of angiotensin converting enzyme inhibitors restores the lower limit of cerebral blood flow autoregulation the chronic effects have not received much attention. We studied the effect of the angiotensin converting enzyme inhibitor, perindopril, on mean arterial pressure, basal cerebral blood flow and cerebral blood flow autoregulation in renovascular hypertensive (two-kidney, one clip model) and normotensive male Wistar rats.
