Abstract:
:A mechanism has been proposed in which nitric oxide (NO) may bind to cysteine beta93 and be transported by haemoglobin from the lungs to the tissues and modify vascular tone. In addition, it has been reported that treatment of sickle cell anaemia blood with 80 p.p.m. NO gas in air shifts the oxygen affinity, as measured by P50 to the left. We exposed normal and sickle cell anaemia blood to 80 p.p.m. NO in air for 1 h in vitro and found no change in P50 of either normal or sickle cell blood. In addition, we exposed normal and sickle cell blood in buffer to aqueous NO (NO gas dissolved in buffer) at varying concentrations and found that the induced left shift in P50 correlates strongly and linearly with methaemoglobin formation. We also treated normal and sickle cell blood with other nitric oxide donors, such as sodium 2-(N, N-diethylamino)-diazenolate-2-oxide (DEANO), S-nitrosocysteine (CysNO) and sodium trioxodinitrate (OXINO, or Angeli's salt). In all cases, we found a dose-dependent increase in methaemoglobin that was strongly correlated with the dose-dependent P50 reduction. Our data do not support the report that low NO concentrations can selectively increase the oxygen affinity of sickle cell blood without affecting methaemoglobin levels significantly. NO, however, may have benefit in sickle cell disease by other mechanisms.
