Journal ArticleDOI
Measurement of catalase activity in tissue extracts.
Journal ArticleDOI
The generation of hydrogen peroxide, superoxide radical, and hydroxyl radical by 6-hydroxydopamine, dialuric acid, and related cytotoxic agents.
Gerald Cohen,Richard E. Heikkila +1 more
TL;DR: The results point to a reaction between H2O2 and O2- (Haber-Weiss reaction) as a major source of the ·OH radicals and to a combined action of blocking ·OH formation as well as accelerating its removal.
Journal ArticleDOI
Studies on the distinction between uptake inhibition and release of (3H)dopamine in rat brain tissue slices.
TL;DR: It was possible to conclude that, in the tissue slice system, an experimentally observed release was real, whereas a releasing action evoked an apparent inhibition of uptake equal in magnitude to the releasing action.
Journal ArticleDOI
Alkaloids from Catecholamines in Adrenal Tissue: Possible Role in Alcoholism
Gerald Cohen,Michael Collins +1 more
TL;DR: Condensation reactions occurred in cow adrenal glands perfused with dilute aldehyde solutions at 37�C to form 1,2,3,4-tetrahydroiso-quinoline alkaloids, which could play a role in altering an individual's behavior during and after the ingestion of alcohol.
Journal ArticleDOI
6-Hydroxydopamine: Evidence for Superoxide Radical as an Oxidative Intermediate
Richard E. Heikkila,Gerald Cohen +1 more
TL;DR: Observations demonstrate the formation of the superoxide radical during the autoxidation process, which may be relevant to the mechanism of adrenergic nerve terminal degeneration caused by 6-hydroxydopamine.
