45CaCl2 uptake at low (5 mM), and high, depolarizing (65 mM) KCl concentration was measured in a fraction enriched in astrocytes, a crude mitochondrial-synaptosomal (P2) preparation and in purified synaptosomes derived from normal rats and from rats with thioacetamide-induced acute hepatic
Portal-systemic encephalopathy (PSE) is associated with an increased brain tissue turnover of serotonin (5-HT). Despite increased 5-HT metabolism, brain 5-HT release in rats with a portacaval shunt (PCS) seems to be unaltered. Although this may indicate that the overall 5-HT output is unaltered in
The effects of depolarizing stimuli; high (50 mM) potassium ions and the glutamate receptor agonists N-methyl-D-aspartate, kainate and 2-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA) on the release of newly-loaded [3H]dopamine were studied in frontal cortical and striatal slices from control
OBJECTIVE
Minimal hepatic encephalopathy (MHE) is one of the possible complications of liver cirrhosis. In this study, a potassium-iron-phosphate-citrate complex was analyzed for its efficacy and safety in the treatment of MHE, as this complex is supposed to bind to the major pathogenic factor of
Renal function was evaluated in 80 patients with hepatic coma stage III-IV (24 patients had acute fulminant hepatic failure, 48 patients chronic hepatic failure, 8 patients had a mixed form). Urea, creatinine and electrolytes were measured in plasma and urine as well as creatinine clearance and
OBJECTIVE
The aim of this study was to investigate whether hypokalemia prognosticates outcomes in hepatic encephalopathy. We also examined other potential prognostic variables such as serum pH, systemic vascular resistance (SVR) and serum ammonia levels.
METHODS
Patients with cirrhosis who were
One year prospective study of 25 cirrhotic patients with portal systemic encephalopathy (PSE) admitted to the Emergency Care Centre in Belgrade was performed in order to investigate the significance of clinical, biochemical and electroencephalographic (EEG) parameters and blood ammonia in the
The possible involvement of taurine in the pathogenesis of hepatic encephalopathy was studied in rats injected with thioacetamide. Spontaneous release of exogenous labeled taurine was not affected in any brain area studied, but the potassium-stimulated release was enhanced in the striatum in
A 54-year-old man who had been administered chlormadinone acetate 3 months after prostatectomy for prostate cancer, acutely developed disorientation and memory disturbance. Six days later, he experienced high grade fever and epigastralgia. He was suspected to have hepatic encephalopathy, because the
BACKGROUND
Cirrhotic patients who were hospitalized due to acute variceal bleeding and subsequently developed hepatic encephalopathy during hospital stay had dreadful outcome and high mortality rate. Recommendations regarding management and prevention of encephalopathy in these patients are not
BACKGROUND
Hepatic encephalopathy may be initiated by many factors such as gastrointestinal bleeding, infections, fluid and electrolyte disturbances. Hypokalemia is one of the most commonly encountered electrolyte abnormalities causing hepatic encephalopathy in patients with cirrhosis.
METHODS
We
