Summary
Background: Sepsis-associated encephalopathy (SAE) is defined as a diffuse or multifocal cerebral dysfunction that generally occurs early during severe sepsis. The complete pathophysiology of SAE is unknown, but several mechanisms including endotoxins, inflammatory mediators, the alteration of amino acids and of neurotransmitters, apoptosis, oxidative stress, and blood-brain barrier dysfunction have been suggested. The aim of the present study was to explore the relationship between behavioral stereotypy and plasma levels of tumor necrosis factor-alpha (TNF-alpha) and malondialdehyde (a marker of lipid peroxidation), and brain homovanillic acid content (a marker of dopamine turnover) in a surgically induced sepsis model in rats.
