  • Patent number: 6986984
    Abstract: Red blood cells are purified by defibrinating whole blood and then filtering the defibrinated whole blood, whereby at least a portion of a plasma component is separated from the red blood cells to form a suspension of red blood cells, thereby purifying the red blood cells. Whole blood is defibrinated by, for example, using a chemical coagulating agent or mechanical agitation. Separation of the plasma component from red blood cells can be completed by, for example, diafiltration. The suspension of red blood cells can then be employed to produce a hemoglobin-based oxygen carrier.

  • Patent number: 6936423
    Abstract: Lethal Toxin Neutralizing Factor has been isolated in purity from opossum serum by high pressure liquid chromatography (HPLC) fractionation. The amino acid sequence from the N-terminal for the first fifteen amino acids of LTNF-n is: Leu Lys Ala Met Asp Pro Thr Pro Pro Leu Trp Ile Lys Thr Glu. Antibodies to LTNF-n and synthetic peptides consisting of fifteen, ten and five amino acids from the N-terminal of the above sequence, designated as LTNF-15, LTNF-10 and LTNF-5 were produced by immunizing Balb/C mice to produce Anti-LTNF-n, Anti-LTNF-15, Anti-LTNF-10 and Anti-LTNF-5. The anti LTNF-n, anti-LTNF-15, anti-LTNF-10 and anti-LTNF-5 react immunologically with all types of toxins derived from animal, plant and bacteria and can be assayed by immunological in vitro test such as ELISA tests. Anti-LTNFs react roughly proportional to lethal dose of biological toxins under in vitro immunological ELISA test similar to the mouse bioassay test.

  • Patent number: 6855691
    Abstract: Nitric oxide (NO) interacts with hemoglobin (Hb) at its metal centers, whereas S-nitrosothiols (RSNOs) can donate the NO group to ?93 cysteine residues, thereby shielding the NO functionality from heme inactivation. S-nitrosylation of Hb is under the allosteric control of oxygen and the oxidation state of heme. NO group release from S-nitrosohemoglobin (SNO-Hb) is further facilitated by intracellular low molecular weight thiols, forming RSNOs which can be exported from the erythrocyte to regulate blood pressure. Hence, a dynamic cycle is established in which S-nitrosylation of Hb is initiated in the lung following oxygenation of red blood cells and is completed by SNO-Hb metabolism during arterial-venous transit. SNO-Hb can be formed by reaction of Hb with S-nitrosothiol. This procedure avoids oxidation of the heme.

Sensitive organisms include Gram-negative bacteria such as Escherichia coli and Pseudomonas aeruginosa, Gram-positive bacteria such as Staphylococcus aureus and Streptococcus faecalis, and the fungus Candida albicans. Methods for preparing the compositions also are provided.

  • Patent number: 6291424
    Abstract: Nitrosylation of proteins and amino acid groups enables selective regulation of protein function, and also endows the proteins and amino acids with additional smooth muscle relaxant and platelet inhibitory capabilities. Thus, the invention relates to novel compounds achieved by nitrosylation of protein thiols. Such compounds include: S-nitroso-t-PA, S-nitroso-cathepsin; S-nitroso-lipoprotein; and S-nitroso-immunoglobulin. The invention also relates to therapeutic use if S-nitroso-protein compounds for regulating protein function, cellular metabolism and effecting vasodilation, platelet inhibition, relaxation of non-vascular smooth muscle, and increasing blood oxygen transport by hemoglobin and myoglobin. The compounds are also used to deliver nitric oxide in its most bioactive form in order to achieve the effects described above, or for in vitro nitrosylation of molecules present in the body.

  • Patent number: 6284871
    Abstract: The present invention relates to biologically active peptides which specifically inhibit the Factor IX-dependent pathway of blood coagulation. These peptides are based on a specific motif which represents a sequence of Factor VIII (amino acid 1811-1818) involved in binding to activated Factor IX as well as to the intact Factor IX zymogen. Binding of said peptides to Factor IX or activated derivatives thereof effectively inhibits complex assembly with Factor VIII. These peptides thereby specifically interfere in the Factor IX-dependent pathway of thrombin formation, while leaving other haemostatic pathways unaffected. By virtue of this unique specificity, the peptides of this invention are particularly useful in novel pharmaceutical compositions for the treatment of thrombotic disorders.

  • Patent number: 6197745
    Abstract: S-nitrosothiols (RSNOs) can donate the NO group to the &bgr;93 cysteine residues of hemoglobin (Hb) without inactivating the heme. S-nitrosylation of Hb is under the allosteric control of oxygen and the oxidation state of heme. NO group release from S-nitrosohemoglobin (SNO-Hb) is further facilitated by intracellular low molecular weight thiols, forming RSNOs which can be exported from the erythrocyte to regulate blood pressure and platelet activation. SNO-Hb can be formed by reaction of Hb with S-nitrosothiol. This procedure avoids oxidation of the heme. Other methods can be used which are not specific only for thiol groups, but which nitrosate Hb more extensively, and may produce polynitrosated metHb as a product or intermediate product of the method.
