| Outline of Final Research Achievements |
Recently, the cardioprotective effect of nitrite has been reported, but the effects of nitrite in sepsis is unknown. In this study, we administered nitrite to rats with severe sepsis model by cecal ligation and puncture, and examined its cardioprotective effect and safety.
We elucidated that 1mg / kg of nitrite improved a cardiac contractility and myocardial mitochondrial function. Furthermore, in vivo hemodynamic, blood inflammatory cytokines, and myocardial nitrating stress were not exacerbated by nitrite. Nitrite administration also significantly improved the survival rate of septic rats.
In the present study, our results showed a potential of nitrite for cardioprotection in severe sepsis.
