项目摘要

We aim to understand the toxicifies associated with the acellular hemoglobin (Hb) in the circulation by applying in vivo microvascular tools and methods. Our results will expand the knowledge and therapeutic alternatives to hemolyfic pathologies, blood transfusions and Hb-based oxygen carriers (HBOCs). Toxicity will be analyzed in terms of microcirculatory phenomena measured by quantifying changes in funcfional capillary density (FCD) in a hamster window chamber model. FCD is a general functional biomarker that integrates systemic, cardiovascular, cellular, and biochemical changes resulfing from Hb-based transfusions. We will use Hbs generated by recombinant technology and chemical modificafions that emphasize each of the properties that leads to a

我们的目标是通过应用了解与循环中无细胞血红蛋白 (Hb) 相关的毒性体内微血管工具和方法。我们的结果将扩大知识和治疗替代方案溶血性病变、输血和血红蛋白载氧体 (HBOC)。毒性分析将在通过量化功能性毛细血管密度（FCD）的变化来测量微循环现象仓鼠窗室模型。 FCD 是一种通用功能生物标志物，整合了系统、基于 Hb 的输血导致心血管、细胞和生化变化。我们将使用 Hbs 通过重组技术和化学修饰产生，强调了每一个特性导致
