Outline of Final Research Achievements

In the present study, we revealed that oligodendrocytic apoptosis occurred in corpus callosum after severe traumatic brain injury, and that hydrogen gas inhalation therapy which could scavenge toxic free radicals suppressed axonal injury in corpus callosum and oligodendrocytic apoptosis. Further, hydrogen gas inhalation therapy combined with glycyrrhizin administration which could suppress HMGB1 revealed more suppression of axonal injury and oligodendrocytic apoptosis. The combination therapy including hydrogen gas inhalation and HMGB1 suppression might be novel therapy for severe traumatic brain injury.
