【 摘 要 】

Omega-3 fatty acid administration can affect the release of neurotransmitters and reduce inflammation and oxidative stress, but its use in traumatic brain injury (TBI) has not been described extensively. We investigated the effect of 7 day oral fish oil treatment in the recovery of potassium evoked dopamine release after TBI. Sham rats and TBI rats were given either olive oil or fish oil by oral gavage and were subject to cerebral microdialysis. Olive oil treated TBI rats showed significant dopamine release deficit compared to sham rats, and this deficit was restored with oral fish oil treatment. There was no effect of fish oil treatment on extracellular levels of dopamine metabolites such as 3,4-dihydroxyphenylacetic acid and homovanillic acid. These results suggest the therapeutic potential of omega-3 fatty acids in restoring dopamine neurotransmission deficits after TBI. Published by Elsevier Ireland Ltd.
