Inhibition of nitric oxide synthase activity improves focal cerebral damage induced by cerebral ischemia/reperfusion in normotensive rats
Introduction: Nitric oxide seems to play a dual role in ischemia/reperfusion injury. Few studies have investigated whether it exacerbates or improves brain edema. In the present study, we inhibited the activity of nitric oxide synthase by L-NAME and evaluated the cerebral infarct volume, tissue swelling and brain edema, alongside the measurement of blood flow of the ischemic region. Methods...
متن کاملThe effect of nitric oxide synthase inhibition on infarct volume after reversible focal cerebral ischemia in conscious rats.
BACKGROUND AND PURPOSE Previous in vitro and in vivo studies of the effects of nitric oxide synthase inhibition in the central nervous system have yielded conflicting results concerning the role of nitric oxide in the events that lead to ischemic injury. In this study, we tested the hypothesis that preischemic inhibition of nitric oxide synthase increases infarct volume after reversible focal c...
متن کاملContribution of Nitric Oxide Synthase (NOS) Activity in Blood-Brain Barrier Disruption and Edema after Acute Ischemia/ Reperfusion in Aortic Coarctation-Induced Hypertensive Rats
Background: Nitric oxide synthase (NOS) activity is increased during hypertension and cerebral ischemia. NOS inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (BBB) disruption and cerebral edema formation during stroke in acute hypertension. Here, we investigated the role of NOS inhibition in progression of edema formation and BBB d...
متن کاملL-NAME and 7-Nitroindazole Reduces Brain Injuries in Transient Focal Cerebral Ischemia in Rat
Background: The role of nitric oxide (NO) of endothelial or neuronal origins in cerebral ischemia and reperfusion injuries are far from being settled, extending from being important to not having any role at all. Objective: To investigate the role of NO of endothelial and neuronal origins in ischemia/reperfusion injuries in focal cerebral ischemia, L-NAME, a non selective NO synthase inhibitor...
