| Outline of Final Research Achievements |
The efficacy of cholinergic stimulation for hypoxic-ischemic brain damage was evaluated in newborn rats. Cholinergic stimulation showed a marked reduction of brain damage, on the other hand, cholinergic inhibition showed a marked exacerbation. Regional specificity was observed for both microglial activation and susceptibility to cholinergic stimulation after hypoxia-ischemia. IL-1β production was also noted on hypoxic-ischemic brain. Regional microglial activation and IL-1β production was significantly reduced with timely cholinergic stimulation. Thus, we demonstrated that cholinergic stimulation reduced brain damage with a suppressive effect on microglial activation and IL-1 in a newborn rat model of hypoxia-ischemia. Under hypoxic-ischemic environments, activation of the cholinergic inflammatory response is effective against perinatal brain damage.
