Abstract
Background: Epoxyeicosatrienoic acids (EETs) are cytochrome P450 metabolites of arachidonic acid produced by the vascular endothelium and act as important regulators of vascular tone.
Objectives: to study the effect of soluble epoxide hydrolase inhibition AUDA on endothelial function in hypercholesterolemic rats.
Methods: Hypercholesterolemia was induced by using Matos diet for 8 weeks and it significantly increased TC, TG, and LDL-C and decreased HDL-C. AUDA, was used with a dose of 0.35 mg/ kg for 10 weeks via gastric gavage every other day.
Results: AUDA treated group has significantly lower total-C, TG, LDL-C and higher HDL-C as compared to untreated group. AUDA also improved vascular reactivity and vasodilatory response to different doses of Acetyl choline. Histopathological examination of aortic rings showed reduced development of atherosclerotic changes in the vascular wall with no effect on e-NOS expression in vascular endothelial cells.
Conclusions: We can conclude that AUDA treatment has improved lipid profile and protect against development of atherosclerotic histopathological changes.
