Protective effect of beta-glucan against oxidative organ injury in a rat model of sepsis.
Sepsis leads to various organ damage and dysfunction. One of the underlying mechanisms is thought to be the oxidative damage due to the generation of free radicals. In this study, we investigated the putative protective role of beta-glucan against sepsis-induced oxidative organ damage. ⋯ The results demonstrate that sepsis significantly decreased GSH levels and increased the MDA levels and MPO activity (p<0.05-p<0.001) causing oxidative damage. Elevated plasma TNF-alpha levels in septic rats significantly reduced to control levels in beta-glucan treated rats. Since beta-glucan administration reversed these oxidant responses, it seems likely that beta-glucan protects against sepsis-induced oxidative organ injury.
