Melatonin protects from, but does not reverse, the effects of mediators of sepsis on liver bioenergetics

摘要

Reactive oxygen species (ROS) have been reported to play a significant role in the pathogenesis of sepsis and liver dysfunction. In particular, neonates are at risk for sepsis and have less protection against oxidation. Melatonin has been reported to reduce the oxidative stress status in neonates with sepsis. Little is known about the effect of melatonin on liver bioenergetics. The aim of this study was to investigate the protective effect of melatonin on hepatocyte oxidative energy metabolism against hydrogen peroxide (H2O2), a free radical mediator of septic damage.
