Alterations In Rat Brain Norepinephrine And Dopamine Levels And Synthesis Rates In Response To Five Neurotoxic Chemicals: Acrylamide, 2,5-Hexanedione, Tri-O-Tolyl Phosphate, Leptophos, And Methyl Mercuric Chloride, Charles N. Aldous

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Acrylamide, 2,5-hexanedione, Tri-o-tolyl phosphate and leptophos belong to three fundamentally different chemical classes but all four chemicals cause central-peripheral distal axonopathy. Some of these compounds have been shown to alter brain steady state levels of neurotransmitters or to inhibit the activities of adenosine triphosphatases which are involved in the uptake and storage of biogenic amines. Tests were performed to determine alterations in steady state levels of rat brain norepinephrine and dopamine in response to doses of the above chemicals and of the central nervous system toxin, methyl mercuric chloride sufficient to cause ataxia. Catecholamine synthesis rate constant estimations were performed. …
