    • The present invention concerns a process for inactivating an extracellular lipid enveloped human pathogenic virus and/or an intracellular human pathogenic virus which may be present in a blood cell composition containing ≧1×109 cells/ml by contacting that composition with a virucidally effective amount of at least one photoreactive compound having an absorption maximum of ≧630 nm, light and oxygen and/or a quencher. In one embodiment of the invention, the process is conducted under conditions whereby a structural integrity of greater than 80% of at least one type of blood cell contained within said composition is retained. Another embodiment of the invention relates to a process for inactivating an extracellular lipid enveloped human pathogenic virus and/or an intracellular human pathogenic virus which may be present in a composition containing at least one coagulation factor while retaining at least 77% of said coagulation factor by contacting said composition with a virucidally effective amount of at least one photoreactive compound, light and a quencher. The processes of the invention can be used to prepare blood products, which, in turn, are suitable for transfusion into a recipient in need of such transfusion.
    • 本发明涉及一种灭活细胞外脂质包膜的人类病原体病毒和/或细胞内人类病原体病毒的方法,该方法可以存在于含有≥1×10 9个细胞/ ml的血液细胞组合物中,通过使该组合物与病毒有效量的 至少一种光吸收最大值> 630nm的光反应性化合物,光和氧和/或猝灭剂。 在本发明的一个实施方案中,该方法在保持所述组合物中所含的至少一种类型的血细胞的大于80%的结构完整性的条件下进行。 本发明的另一个实施方案涉及用于灭活细胞外脂质包膜的人类病原体病毒和/或细胞内人致病性病毒的方法,所述细胞外脂质包封的人类病原体病毒和/或细胞内人致病性病毒可存在于含有至少一种凝血因子的组合物中,同时将至少77%的所述凝血因子保留 使所述组合物与杀病毒有效量的至少一种光反应性化合物,光和猝灭剂接触。 本发明的方法可以用于制备血液制品,血液制品又适合于输血到需要这种输血的接受者中。
