肺泡蛋白沉积症患者肺泡内充满富含表面活性物质成分,尤其是表面活性物质蛋白A(SP-A)。为明确肺泡蛋白沉积症的病因是SP-A分泌过多还是清除减少,或是两者皆有,作者对全肺灌洗后的支气管肺泡灌洗液(BALF)成分进行分析。
Alveolar proteinosis patients alveolar filled with surfactant-rich ingredients, especially surfactant protein A (SP-A). To determine whether the cause of pulmonary alveolar proteinosis is excess or clearance of SP-A or both, the authors analyzed the composition of bronchoalveolar lavage fluid (BALF) after whole lung lavage.
