Abstract
Nitrosylhemoglobin can be produced by introducing gaseous NO into an aqueous solution of hemoglobin. It has been demonstrated that nitrosylhemoglobin in aqueous solution can be converted to SNO-hemoglobin upon introduction of oxygen to the solution, as is postulated to occur in the lungs. Nitrosylhemoglobin can be used in methods to produce the physiological effects of NO, for example, to reduce vasoconstriction and to inhibit platelet aggregation.
Claims
exact text as granted — not AI-modified1 . A method for increasing delivery of oxygen and decreasing delivery of NO in a mammal, comprising administering to the mammal a composition comprising a low molecular weight thiol and isolated hemoglobin, wherein the thiol is cysteine or N-acetylcysteine.
2 . A method for increasing delivery of oxygen and increasing delivery of NO in a mammal, the method comprising administering to the mammal a composition comprising a low molecular weight nitrosothiol and isolated hemoglobin, wherein the low molecular weight nitrosothiol is S-nitrosocysteine, S-nitrosohomocysteine, or S-nitrosocysteinylglycine.Join the waitlist — get patent alerts
