Effects of sesame oil on oxidative stress and hepatic injury after cecal ligation and puncture in rats.

Abstract

Oxidative stress is known to be involved in the development of organ failure and death in sepsis. Sesame oil attenuates oxidative stress induced by endotoxin; however, whether sesame oil is still effective in rats with sepsis has never been investigated. The aim of the present study was to determine the effect of sesame oil on oxidative stress-associated hepatic injury in cecal ligation and puncture-induced rats with sepsis. We examined the effect of sesame oil (4 mL/kg daily for 1 week) on lipid peroxidation, hydroxyl radical, superoxide anion, and nitrite levels in rats with sepsis. In addition, hepatic injury was also assessed by blood biochemistry. Sesame oil significantly decreased lipid peroxidation and serum nitrite levels, but affected neither superoxide anion nor hydroxyl radical in cecal ligation and puncture-treated rats. Furthermore, sesame oil significantly attenuated cecal ligation and puncture-induced hepatic injury in rats. Nevertheless, oxidative stress and hepatic injury were not affected by corn oil or mineral oil in rats with sepsis. Thus, attenuation of oxidative stress and hepatic injury may be associated with inhibition of nitric oxide in sesame oil-associated protection in rats with sepsis.
