    Abstract: Herein it is shown that hemoproteins (e.g., Ascaris hemoglobin, myoglobin, flavohemoglobins) have NO-consuming and deoxygenase activities. The invention provides a method of reducing the concentration of oxygen and/or nitric oxide in a mammal. The method of the invention comprises administering a therapeutically effective amount of a hemoprotein having NO-activated deoxygenase activity or an enzymatically active fragment thereof to a mammal. The method can be used to treat a mammal having pathologically proliferating cells, such as a tumor. In one embodiment, the hemoprotein is administered to reduce the oxygen concentration of a tumor. In another embodiment, the hemoprotein is administered together with a cytotoxic agent to treat a mammal having a tumor. The invention also provides a method of enzymatically generating toxic reactive oxygen species in a mammal for therapeutic purposes. The method comprises administering a therapeutically effective amount of a hemoprotein to a mammal. The invention also provides a composition comprising a hemoprotein having deoxygenase activity or an enzymatically active fragment thereof and a physiologically acceptable carrier. In one embodiment, the composition further comprises a cytotoxic agent and/or a reducing agent. The invention further provides a method of treating a mammal infected with Ascaris sp., comprising administering to said mammal a therapeutically effective amount of an inhibitor of NO synthase. The NO-consuming activity of a hemoprotein (e.g., a flavohemoglobin) can be used in a treatment where constriction of blood vessels is desirable, or where it is otherwise desirable to reduce NO concentration, as in inflammation.

    Abstract: Disclosed are novel polymers derivatized with at least one nullSNO group per 1200 atomic mass unit of the polymer. In one embodiment, the S-nitrosylated polymer has stabilized nullS-nitrosyl groups. In another embodiment the S-nitrosylated polymer prepared by polymerizing a compound represented by the following structural formula: 1 R is an organic radical. Each Xnull is an independently chosen aliphatic group or substituted aliphatic group. Preferably, each Xnull is the same and is a C2-C6 alkylene group, more preferably nullCH2null, nullCH2CH2null, nullCH2CH2CH2null or nullCH2CH2CH2CH2null. p and m are independently a positive integer such that pnullm is greater than two. The polymers of the present invention can be used to coat medical devices to deliver nitric oxide in vivo to treatment sites.

    Abstract: Pulmonary disorders in which the GSNO pool or glutathione pool in the lung is depleted and where reactive oxygen species in lung are increased, are treated by delivering into the lung as a gas, agent causing repletion or increase of the GSNO pool or protection against toxicity and does so independently of reaction with oxygen. Agents include ethyl nitrite, NOCl, NOBr, NOF, NOCN, N2O3, HNO, and H2S. Optionally, N-acetylcysteine, ascorbate, H2S or HNO is administered in addition to other GSNO repleting agent to potentiate the effect of said agent.

    Abstract: A blood-flow decrease preventing agent is used to negate or reduce the decreased oxygen delivery in abdominal organs caused by insufflating gas. Preferably a gas is delivered into the abdominal cavity consisting essentially of the insufflating gas and the blood-flow decrease preventing agent. Very preferably, a gas is used consisting essentially of carbon dioxide as the insufflating gas and ethyl nitrite as the blood-flow to abdominal organ decrease preventing agent.

    Abstract: Red blood cells can be loaded with low molecular weight nitrosylating agents, such as S-nitrosothiols, to act as a delivery system for NOnull groups to tissues. Loaded red blood cells can be used in methods of therapy for conditions which are characterized by abnormal O2 metabolism of tissues, oxygen-related toxicity, abnormal vascular tone, abnormal red blood cell adhesion, or abnormal O2 delivery by red blood cells. Such treatment of red blood cells can be extended to in vivo therapies, with the object to achieve an increase in the ratio of red blood cell S-nitrosothiol to hemoglobin.
