成人呼吸窘迫综合征(ARDS)是一种肺急性炎症性疾病。病变特点为肺毛细血管充血、肺泡透明膜形成和内皮细胞增生。有研究表明,ARDS 时补体破激舌,并在炎症反应中起重要作用。作者为确定脓毒血症病人ARDS 发作前和缓解前补体的激活途径,用ELISA 试难分别对补体激活经典和替代途径过程中产生的C_(1r)C_(1s)-C_1抑制因子复合物和C_(3b)P 复合物进 Adult respiratory distress syndrome (ARDS) is an acute pulmonary inflammatory disease. Lesions characterized by pulmonary capillary congestion, alveolar hyaline membrane formation and endothelial cell proliferation. Studies have shown that, when ARDS complement disrupt the tongue, and play an important role in the inflammatory response. To determine the pathway of complement activation before and after ARDS onset in patients with sepsis, it is difficult to measure the complement of C_ (1r) C_ (1s) -C_1 inhibitor complex during complement activation of classical and alternative pathways by ELISA C_ (3b) P complex into
