Ethanol is a powerful generator of oxygen free radicals, when metabolized in the liver or in other organs. Isoenzyme 2E1 of cytochrome P450 and aldehyde oxidase are the main mechanisms for the generation of these radicals. A consequence of free radic

Previous studies have investigated putative alterations in histamine and histamine receptors in schizophrenia, and evidence in favour of the role of this amine as a neurotransmitter or as a neuromodulator was found. In the present study the activity

The effect of different concentrations of aluminum sulphate on the nonenzymatic oxidation of dopamine was studied in order to evaluate the action of this metal on neuromelanin synthesis. Data shows that under the studied conditions, aluminum partiall

The oxygen uptake during the reaction of dopamine autoxidation was studied and it was found that it may occur through two distinct oxidative pathways. One involves the univalent reduction of oxygen, forming the superoxide radical, the other involves

Oxygen free radicals may be generated during ethanol metabolization by cytochrome P450, or due to the formation of xanthine oxidase by ethanol effect on xanthine dehydrogenase. After transformation into acetaldehyde, the metabolism of this compound b
