| Outline of Final Research Achievements |
NO inhalation is now known to have protective effect even in distant organs. The purpose of the present study is to prove the usefulness of perioperative NO inhalation therapy for the central nervous protection. Thus, using the spinal cord ischemia animal model, the effect of NO inhalation (80ppm) on spinal cord tissue oxygen partial pressure (PspO2) and spinal cord blood flow (r-SCBF) was examined. As a result, PspO2 in NO inhalation group was significantly improved compared than that in control group (non-NO inhalation) at ischemic period (after aortic clamping to aortic de-clamping). However, in reperfusion period such differences were not found. r-SCBF also showed the similar change with PspO2 that maintained significantly by NO inhalation during spinal cord ischemia. After reperfusion, the effect of NO inhalation was attenuated because of aerobic environment.
Therefore, NO inhalation therapy could be suggested to contribute on the protection of central nervous system.
