    摘要: Methods for preparation of a heat stable hemoglobin based oxygen-carrier-containing pharmaceutical composition such that beta-beta cross-linking is favored are provided. Using the methods of the present invention, the oxygen affinity of the resultant molecule can be controlled so that hemoglobin based oxygen carriers tailored for specific applications can be produced. Lower oxygen affinity crosslinked hemoglobin is useful for applications requiring rapid tissue oxygenation (e.g. hemorrhagic shock) while higher oxygen affinity cross-linked hemoglobin is useful for applications requiring a slower rate of oxygenation (e.g. cancer adjunct therapy). A highly purified and heat stable crosslinked non-polymeric tetrameric hemoglobin having beta-beta cross-linking of greater than 40-60% and suitable for use in mammals without causing renal injury and vasoconstriction is produced. A high temperature and short time (HTST) heat processing step is performed to effectively remove any undesired dimeric hemoglobin, non-crosslinked tetrameric hemoglobin, and plasma protein impurities.

    摘要: A highly purified and heat stable cross-linked nonpolymeric tetrameric hemoglobin suitable for use in mammals without causing renal injury and vasoconstriction is provided. A high temperature and short time (HTST) heat processing step is performed to remove undesired dimeric form of hemoglobin, uncross-linked tetrameric hemoglobin, and plasma protein impurities effectively. Addition of N-acetyl cysteine after heat treatment and optionally before heat treatment maintains a low level of met-hemoglobin. The heat stable cross-linked tetrameric hemoglobin can improve and prolong oxygenation in normal and hypoxic tissue. In another aspect, the product is used in the treatment of various types of cancer such as leukemia, colorectal cancer, lung cancer, breast cancer, liver cancer, nasopharyngeal carcinoma and esophageal cancer. The inventive tetrameric hemoglobin can also be used to prevent tumor metastasis and recurrence following surgical tumor excision. Further the inventive tetrameric hemoglobin can be administered to patients prior to chemotherapy and radiation treatment.
