| Outline of Final Research Achievements |
Animal study is helpful to investigate therapeutic approaches to control increased vascular permeability, which worsens clinical outcomes in critically ill patients. However, conventional technique to quantify vascular permeability requires sacrifice of animals. We aimed to develop a non-invasive technique to quantify vascular permeability in mouse models, and then, investigated new therapeutic approaches to control vascular permeability. First, we found footpad fluorescent intensity assessed by an in vivo fluorescent imaging system had a strong correlation to lung fluorescent intensity, and had a same trend of severity of lung vascular permeability assessed by a conventional technique. Thus, the footpad fluorescent intensity assessment can be use to a non-invasive technique to quantify lung vascular permeability. Next, we found the erythropoietin may control vascular permeability in septic mouse. Further studies are warranted to establish ways to control vascular permeability.
