- Therefore, the present approach for making blood substitutes is to use hemoglobin extracted from red blood cells. 因此,目前制备血液替代品的方法是利用从血红细胞中提取血红蛋白。
- Further more, blood substitutes can be stored for more than one year, as compared with about one month for donor blood stored using standard methods. 再者血液替代品能储存一年多,而捐献者的血液利用标准方法仅能储存大约一个月。
- Therefore,the present approach for making blood substitutes is to use hemoglobin extracted from red blood cells. 因此,目前制备血液替代品的方法是利用从血红细胞中提取血红蛋白。
- Had there been a serious development effort in the 1960s,blood substitutes would have already been available in 1986. 如果从20世纪60年代起就开始全力研究,那么到1986就会获得血液替代品。

- Concentrated efforts to develop blood substitutes for public use only seriously started after 1986 because of public concerns regarding HIV) in donor blood. 但是真正集中精力开始开发血液替代品并用于公众,是在1986年之后,因为人们关心着供体血液中的HIV病毒。
- All the above modifications also result in blood substitutes that have a greater ability to release oxygen to the tissues than do red blood cells. 所有以上的修改,也使血液替代品释放氧气给组织的能力比血红细胞大得多。
- Thus, researchers are working on more complicated, third-generation blood substitutes that will encapsulate hemoglobin and the required enzymes inside artificial red blood cells. 因此,研究者研究出了更复杂的第三代血液替代品,它将血红蛋白以及在人造血红细胞内所需要的酶包裹起来。
- Unlike red blood cells,blood substitutes can be pasteurized,filtered and chemical-cleansed to make them sterile. 不像血红细胞,血液替代品能进行巴式灭菌、过滤和化学净化使之无菌。

- Hemolink is just one of a half-dozen blood substitutes that are nearing the market after decades of research. 血链只是经过几十年的研究后即将投放市场的6种血液替代物之一。
- The present,first-generation blood substitutes are mainly effective for short-term uses because of their brief circulation time. 目前由于第一代血液替代品短暂的循环时间,因此它主要对短期应用有效。
- Further more,blood substitutes can be stored for more than one year,as compared with about one month for donor blood stored using standard methods. 再者血液替代品能储存一年多,而捐献者的血液利用标准方法仅能储存大约一个月。
- In addition to the hemoglobin substitutes discussed so far, there is another type of blood substitutes based on perfluorochemicals, synthetic fluids in which oxygen can dissolve. 此外对血红蛋白替代品更深人的讨论,在于能有基于全氟化合物的血液替代品,氧气能溶解在这种合成液体中。
