Reactive microglial cells and macrophages appear after trauma to the brain. To investigate the accumulation patterns of reactive microglial cells and macrophages after cortical incision, these cells were stained immunohistochemically with anti-ED1 antibody in the brain sections before and 1, 3, 5, and 7 days after incision. And to ascertain the participation of oxygen free radicals in these cellular reactions, a synthesized free radical scavenger, (+/-)-N,N'-propylenedinicotinamide (AVS) was administered in this model. Rats were administered AVS (300 mg/kg, i.p.) 30 min before, 2.5 h and every 24 h after incision (AVS group), while only saline was administered in the same manner as a control (saline group). In the saline group, both reactive microglial cells and macrophages had already appeared on day 1 post-incision. The former continued to increase in number during the following days, whereas the latter increased in number up to day 3 and thereafter decreased. Both the numbers of reactive microglial cells and macrophages were significantly decreased (P < 0.05) in the AVS group on days 5 and 7. The results suggest the participation of oxygen free radicals in the reaction of microglial cells and macrophages in traumatic brain injury.
