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 کاملComparison of inducible nitric oxide synthase activity in pancreatic islets of young and aged rats
Objective(s):Some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. Incidence of these condition increases with aging. On the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (NOS) activity is also altered in diabetes. In this study, modification in the enzyme activity associated with aging a...
متن کاملNitric Oxide Synthase and Coronary Vasospasm
Nitric oxide (NO), the molecule of the year in 1995 and theme of the Nobel Prize in 1998, started its career as endothelium-derived relaxing factor (EDRF) almost 20 years ago.1 An unusual observation in the rabbit aorta, ie, the unexpected relaxation to acetylcholine only in preparations with endothelium, stimulated the scientific community because of its obvious physiological and clinical pote...
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 کاملPomace olive oil improves endothelial function in spontaneously hypertensive rats by increasing endothelial nitric oxide synthase expression.
BACKGROUND The effect of dietary pomace olive oil, which has the same concentration of oleic acid but a higher proportion of oleanolic acid (OA) than olive oil, was examined on animal models of hypertension for the first time. METHODS During 12 weeks, Wistar Kyoto (WKY) and spontaneously hypertensive rats (SHR) were fed with either a control 2% corn oil diet (BD), or high-fat diets containing...
