AbstractThe objective of this study was to directly assess NO flux in response to intense renal ischemia-reperfusion process. For real time monitoring, endogenous hemoglobin was employed as a natural spin-trap, and HbNO signal for renal venous blood was observed by ESR spectroscopy. We found that after an intense renal ischemia (1 h), blood NO concentration increased and could be detected by ESR hemoglobin trapping during 6 hours of observation. NO release gradually increased during reperfusion, and reached a plateau approximately from 2 h reperfusion. This result may aid to clarify the precise role of postischaemic NO and the relevant mechanism.
