Brain edema in acute liver failure and chronic liver disease: Similarities and differences
(2013)
Hepatic encephalopathy (HE) is a complex neuropsychiatric syndrome that typically develops as a result of acute liver failure or chronic liver disease. Brain edema is a common feature associated with HE. In acute liver ...
Oxidative stress: a systemic factor implicated in the pathogenesis of hepatic encephalopathy
(2013)
Although ammonia is considered the main factor involved in the pathogenesis of hepatic encephalopathy (HE), it correlates well with the severity of HE in acute liver failure, but not in chronic liver disease. Oxidative ...
L-ornithine-L-aspartate in experimental portal-systemic encephalopathy: therapeutic efficacy and mechanism of action
(1998-06)
Strategies aimed at the lowering of blood ammonia remain the treatment of choice in portal-systemic encephalopathy (PSE). L-ornithine-L-aspartate (OA) has recently been shown to be effective in the prevention of ...
Loss of noradrenaline transporter sites in frontal cortex of rats with acute (ischemic) liver failure
(2001)
There is increasing evidence that central noradrenaline (NA) transport mechanisms are implicated in the central nervous system complications of acute liver failure. In order to assess this possibility, binding sites for ...
Role of manganese in the pathogenesis of portal-systemic encephalopathy
(1998-12)
Amongst the potential neurotoxins implicated in the pathogenesis of hepatic encephalopathy, manganese emerges as a new candidate. In patients with chronic liver diseases, manganese accumulates in blood and brain leading ...
Neuropathological changes in the brain of pigs with acute liver failure
(2010-08)
Abstract Objective. Cerebral edema is a serious complication of acute liver failure (ALF), which may lead to intracranial hypertension and death. An accepted tenet has been that the blood-brain barrier is intact and that ...
Systemic oxidative stress is implicated in the pathogenesis of brain edema in rats with chronic liver failure
(2012-04)
Chronic liver failure leads to hyperammonemia, a central component in the pathogenesis of hepatic encephalopathy (HE); however, a correlation between blood ammonia levels and HE severity remains controversial. It is believed ...
Effect of portacaval anastomosis on glutamine synthetase protein and gene expression in brain, liver and skeletal muscle
(1999)
The effects of chronic liver insufficiency resulting from end-to-side portacaval anastomosis (PCA) on glutamine synthetase (GS) activities, protein and gene expression were studied in brain, liver and skeletal muscle of ...
Hypothermia in acute liver failure
(2004)
The development of encephalopathy in patients with acute liver injury defines the occurrence of liver failure. The encephalopathy of acute liver failure is characterized by brain edema which manifests clinically as increased ...
