Can hepatic coma be caused by a reduction of brain noradrenaline or dopamine?

چکیده
Intraventricular infusions of octopamine which raised brain octopamine concentrations more than 20 000-fold resulted in reductions in brain noradrenaline and dopamine by as much as 90% without affecting the alertness or activity of normal rats. As this reduction of brain catecholamines is much greater than any reported in hepatic coma, we do not believe that values observed in experimental hepatic failure have aetiological significance for the encephalopathy that ensues.

متن کاملEFFECTS OF CATECHOLAMINES ON DOPAMINE AND SEROTONIN SYNTHESIS IN RAT BRAIN STRIATAL SYNAPTOSOMES: THE ROLE OF PRESYNAPTIC RECEPTORS AND THE SYNAPTOSOMAL REUPTAKE MECHANISM.
The regulation of dopamine and serotonin synthesis in rat brain striatal synaptosomes has been studied using HPLC methods. Noradrenaline was shown to markedly inhibit both the synthesis of dopamine and serotonin. The response of the synaptosomes to the concentrations of noradrenaline appeared to be biphasic, a very effective inhibition occurring at low concentrations (1-5 µm) and a relativ...
متن کاملChanges in brain catecholamine levels in human cirrhotic hepatic encephalopathy.
Hepatic encephalopathy (HE) is currently felt to be secondary to a disturbance in the metabolism of cerebral catecholamines with a decline in dopamine and noradrenaline and a rise in the false neurotransmitter octopamine. The aim of this study was to evaluate brain tissue levels of dopamine, noradrenaline, and octopamine in patients with cirrhosis and HE. This study includes 34 patients: 22 wer...
متن کاملSome neurochemical effects of amphetamine, methylamphetamine and p-bromomethylamphetamine in the rat.
1. Low doses of D-amphetamine increased brain noradrenaline concentrations in the rat; doses greater than 5 mg/kg, however, caused a decrease. Methylamphetamine also showed this dual effect, but a reduction in brain noradrenaline concentration only occurred when doses greater than 10 mg/kg were administered. p-Bromomethylamphetamine did not significantly reduce brain noradrenaline concentration...
