细菌性肺炎嗜中性粒细胞渗出


高倍镜下,可见以嗜中性粒细胞渗出为主的肺泡。周围肺泡壁毛细血管扩张充血,血管内充满红细胞。这种渗出是细菌性感染的典型表现。渗出引起咳脓性黄痰,如细菌性肺炎。
At high magnification, the alveolar exudate of mainly neutrophils is seen. The surrounding alveolar walls have capillaries that are dilated and filled with RBC's. Such an exudative process is typical for bacterial infection. This exudate gives rise to the productive cough of purulent yellow sputum seen with bacterial pneumonias.
