Portal hypertension is a major complication of human cirrhosis that frequently leads to central nervous system dysfunction. In our study, rats with prehepatic portal hypertension developed hippocampal mitochondrial dysfunction as indicated by decreased respiratory rates, respiratory control and mitochondrial nitric oxide synthase (mtNOS) activity in(More)
The aim of the present study was to characterize the neurophysiological profile of cognitive impairment associated with patients with chronic alcoholic and nonalcoholic liver disease. The authors evaluated 43 patients with cirrhotic liver disease: 19 patients with chronic alcohol ingestion and 24 nonalcoholic patients who had been infected with hepatitis B(More)
Peripheral noradrenergic activity is enhanced in portal hypertension and correlates with the progression of the disease. However, little is known about the status of central norepinephrine (NE) in portal hypertension. The aim of the present work was to study the uptake of NE in several areas rich in NE in experimental prehepatic portal hypertension. The(More)
Several evidences support the hypothesis that central catecholamines may play a significant role in the production and/or maintenance of different alterations that characterize portal hypertension. The aim of the present work was to study the possible modifications in norepinephrine (NE) metabolism in several telencephalic and diencephalic areas rich in NE(More)
