| Outline of Final Research Achievements |
The objective of the present study was to clarify the effects of inhalation of either nitric oxide (NO) or hydrogen gas, or simultaneous inhalation of both gases for a mouse model of lethal septic shock due to severe lung injury.
NO gas inhalation provide beneficial effect such as inhibitions of neutrophil infiltration and vascular permeability increase, but adverse effect such as interleukin-6 (proinflammatory cytokine) increase, and resulted in the no change in the survival. On the other hand, hydrogen gas inhalation cannot inhibit neutrophil infiltration but inhibit vascular permeability increase and did not change interleukin-6 level, and resulted in the improved survival. Simultaneous inhalation of both gases will be a good strategy to reduce adverse effects of NO without eliminating the beneficial effects of NO.
