d-Allose Attenuates Overexpression of Inflammatory Cytokines after Cerebral Ischemia/Reperfusion Injury in Gerbil

Background The present study investigates the effects of d -allose, a rare sugar, on the inflammatory response after transient forebrain ischemia in the gerbil and whether it reduces oxidative stress (8-hydroxyl-2′-deoxyguanosine levels) and behavioral deficits. Methods Transient forebrain ischemia was induced by occlusion of the bilateral common carotid arteries for 5 minutes. d -Allose was intraperitoneally injected immediately after ischemia (400 mg/kg). Inflammatory cytokines and oxidative damage in the hippocampus and behavioral deficits were examined 3 days after ischemia. Results d -Allose administration reduced ischemia-induced cytokine production, oxidative stress, and behavioral deficits (motor and memory related). Conclusions The present results suggest that d -allose reduces brain injury after transient global ischemia by suppressing inflammation as well as by inhibiting oxidative stress.
