| Outline of Final Research Achievements |
The aim of this study is to evaluate the effectiveness of free radical scavenger (edaravone, EV) combined with hypothermia (HT) for hypoxic-ischemic (HI) brain injury, and the safety of hydrogen gas inhalation in neonatal piglets. The following results had been reported. At first, there was a positive linear correlation between changes in cerebral blood volume and low-amplitude aEEG duration during 12 h after the insult in the no-therapy group, but a negative linear correlation between these two parameters in the HT group. Secondly, both HT and HT+EV groups showed lower histopathological cerebral damages compared to that of no-therapy, especially in gray and white matter. However, HT+EV did not show lower damages compared to HT. Lastly, hydrogen gas inhalation had no effects on circulatory and metabolic activities, especially cerebral hemodynamics and oxygen metabolism, and cortical electrical activity. Therefore, hydrogen gas is likely to be used safely in neonatal medicine.
