| Research Abstract |
We studied several biomarkers that could predict the mortality or efficacy of therapy in patients with acute lung injury or acute respiratory distress syndrome (ALI/ARDS). For this aim, we conducted clinical and basic studies. In clinical studies, we sampled blood and alveolar epithelial lining fluid which was facilitated by the method of bronchoalveolar microsampling in ALI/ARDS patients. As a result, we found significantly higher amount of amino-terminal fragment of laminin gamma2-chain in blood and in epithelial lining fluids of patients with ALI/ARDS. And also, neutral endopeptidase (NEP) activity in ALI/ARDS patients were significantly lower compared to control group. In basic studies we conducted the experiments in similar lung injurious settings. In addition, extracellular ATP and moesin expression in association with lung injury were studied using mouse model. These studies confirmed our hypothesis that these biomarkers increase or decrease in accordance with the severity of the disease. Thus these biomarkers should be examined in a larger clinical trial whether it could useful for the physicians.
