Value of Caffeic Acid Phenethyl Ester Pretreatment in Experimental Sepsis Model in Rats

Abstract EN

Background and Aim.

The aim of this study was to determine the actions of caffeic acid phenethyl ester (CAPE) on the changes of endothelin-1 (ET-1) level, tumor necrosis factor- (TNF-) alpha, and oxidative stress parameters such as superoxide dismutase (SOD) activities and malondialdehyde (MDA) levels in experimental sepsis model in rats.

Materials and Methods.

Twenty-four rats were randomly divided into three experimental groups: sham (group 1), sepsis (group 2), and sepsis + CAPE (group 3), n = 8 each.

CAPE was administered (10 µmol/kg) intraperitoneally to group 3 before sepsis induction.

Serum ET-1, serum TNF-alpha, tissue SOD activity, and tissue MDA levels were measured in all groups.

Results.

Pretreatment with CAPE decreased ET-1, TNF-alpha, and MDA levels in sepsis induced rats.

Additionally SOD activities were higher in rats pretreated with CAPE after sepsis induction.

Conclusion.

Our results demonstrate that CAPE may have a beneficial effect on ET and TNF-alpha levels and oxidative stress parameters induced by sepsis in experimental rat models.

Therefore treatment with CAPE can be used to avoid devastating effects of sepsis.
