Abbreviations: CA, cardiac arrest; EET, epoxyeicosatrienoic acid; DHETE, dihydroxyeicosatrienoic acid; HET0016, N-hydroxy-N'-(4-n-butyl-2-methylphenyl)formamidine; HETE, hydroxyeicosatetraenoic acid; ROSC, return of spontaneous circulation.
Eicosanoid levels (pmoL/g tissue) at 5 minutes after ROSC were compared with the vehicle-treated group. HET0016 inhibited 20-HETE levels in the cortex and subcortical region at 5 minutes after ROSC compared with vehicle treatment and did not change the levels of other metabolites, indicating the specificity of HET0016 inhibition for 20-HETE.
P<0.05 HET0016 versus vehicle.
