the mechanism of L-dopa to treat hepatic encephalopathy is?

to increase normal neurotransmitter
to decrease false neurotransmitter
to decrease ammonia
to increase GABA

exogenous hepatic encephalopathy result from?

carbon tetrachloride intoxication
phosphorus intoxication
TNT intoxication
hepatic cirrhosis

hepatic encephalopathy is?

coma result from hepatic failure
neuropsychiatric symptoms occur in hepatic failure
necrosis or degeneration of neuron in hepatic failure
brain edema occur in hepatic failure

what do the false neurotransmitter play on the brain?

disturb the transmit of nerve pulse
disturb the synthesis of neurotransmitter
disturb the energy metabolism of brain
more GABA formed

insufficiency of the ammonia elimination may result from?

urea is decomposed to form ammonia
decreased ammonia secretion of renal tubules
decreased urea syntheses
muscular tic result in hyperammonemia

the precipitating causes of hepatic encephalopathy is?

uptake too much carbohydrate
uptake too much lipid
uptake too much protein
uptake too much water

the major pathogenesis of decreased production of energy in the brain result from hyperammonemia is?

disorder of anaerobic glycolysis
disorder of citric acid cycle
disorder of synthesis of lipid
disorder of urea cycle

endogenous hepatic encephalopathy?

take place slowly
process longer
break out again and again
without precipitating factor

endogenous hepatic encephalopathy may result from?

portal cirrhosis
postenecrotic cirrhosis
acute fulminate hepatitis
primary carcinoma of liver

increased ammonia content in brain leads to?

decreased production of ATP
decreased tyrosine
decreased phenylalanine
decreased GABA
