近年的研究表明,嗜中性白细胞(本文简称白细胞)不仅具有“防御性”功能,在某些条件下受刺激并聚集于血管内的白细胞尚有损伤性作用,肺是最容易受其伤害的器官。白细胞除了释放溶酶体酶之外,新近发现它尚可产生并释放出另外的生物活性因子,参与导致急性肺损伤。 In recent years, studies have shown that neutrophils (hereinafter referred to as leukocytes) not only have a “defensive” function, under certain conditions are stimulated and gathered in the blood vessels of the white blood cells still have damaging effects, the lungs are most susceptible to injury organ. In addition to the release of lysosomal enzymes, leukocytes have recently been found to produce and release additional bioactive factors that lead to acute lung injury.
